• Memory Ram on XPS 8500 64-Bit Installer

  Hello

  Today I installed an another 4 GB Ram in addition to the original 4 GB that she already had.

  However it is said installed memory (RAM): 8,00 (3.48 GB usable) GB

  System type: 64-bit operating system

  Processor: Intel Core i5-3450 CPU @3. 10 Ghz 3.10 Ghz

  Manufacturer: Dell

  Model: XPS 8500

  I had a peek in as well and I don't see any arrangement about the memory.

  3.48 GB usable he showed also when I got only 4 GB installed and I went with the assumption that half of the concert is used by the video card even though it is supposed to have 1 GB of dedicated memory. My graphics card is Nvidia GeForce GT 620 dxdiag.

  My question is how can I get windows to recognize and use all 8 GB of RAM.

  P.S. A moderator can move my post to-> Hardware Forum général Desktop

  Thank you

  I managed to understand.

  I know it's maybe a common thing, but I'll still write my solution here just in case.

  The problem was with reserved Windows hardware. that took like 4.6 GB.

  In difficulty who go to run (windows key + R) and type msconfig and enter.

  In the Startup tab, click the advance Options and deselect maximum memory.

  Restart and now my computer shows all 8 GB of RAM.

  Good luck

• XPS 8500 RAM UPGRADE

  My 8500 XPS came with 4 x 2 GB of ram [total 8 gb] I wanted to update and seen many things on 2 x 8 GB modules.

  When it happens, should I remove the 4 x 2 GB and replace the 2 x 8 GB, or can I let 2 of them in place send me a 20 GB total?

  Assuming that the answer is Yes, are there any order, should I install the new ram, that is to say 1 and 2 housing, or is - this not important?  Also I am on windows 8, I tell him to use more ram?

  s thank you for any help with this.

  According to the data sheet for the XPS 8500, the configs of RAM supported are: 2, 4, 8, 12, 16, 32 GB.

  Assuming that is correct, you will need to remove all four 2 GB modules and install only the two new modules 8 GB for a total of 16 GB.  2 x 8 GB modules must be installed in accommodation for motherboard 1 and 2.

  According to the owner's manual, the slot 1 is SECOND of CPU and slot 2 is FORTH of CPU and their retention fees must be the same color.

  Assuming that the BIOS recognises the new RAM, Windows should know how to use it.

• XPS 8500 - replacement HDD and SSD

  I'm looking to upgrade of storage on my my Dell XPS 8500... My question here is twofold:

  1. I want to replace my current 2 TB HDD (disk storage) with a 4 TB or 5 TB of HARD drive. I will be able to use and see the full 4-5 to? Or is this a case where I will not be able to use the entire disk or will need to score? Y at - it an update of the BIOS that will allow me full access to training?
  2. I am also looking to replace my mSATA 256GB SSD (boot drive) with a 500 GB mSATA SSD... will it be any problem read this disk after installation (plan to do a clean install of Windows and reload my programs)?

  Thanks for your help. Hoping to update soon, but did not buy until I knew what I was getting myself into.

  Its a fairly recent machine with a UEFI BIOS, so it should be good... If you have already upgraded to Windows 10 then your system is already a unit of 10 windows and you should be able to clean the Windows 10 installation on the new SSD. If you haven't you should upgrade now as free upgrade expires tomorrow. #

  You must use the SATA AHCI operation. I assume you have your system already set up this way as you already have a 256 GB mSATA.

• New 750TI of nVidia and XPS 8500 card?

  Wow!

  I had been worried about the power supply power when buying a video card more powerful for my XPS 8500.  700 series from nVidia is the beach, I hope to choose, to replace my 'right' TG 640 card oem.

  The new GTX 750 it looks really good. It's a new radical design and functionality has pointed out, is its low power requirements.

  "Twice the performance and half the energy consumption of the previous generation cards."

  It is now on sale for less than $200.  It's a double-wide.  My question today is: what is the best way to sort the different suppliers of package?

  Dell performs several cards from PNY nVidia in the inventory, so on that ground alone, it will probably be my choice.  Does anyone have experiences of good/bad with them?  What other major suppliers such as: MSI, EVGA or Gigabyte?

  I thank the previous suggestion about the GTX 660, that he would work with the budget of power - but this 750 TI deserves a thorough review for any owner of XPS 8500, wanting a better map of the game. If one cannot not have shoe horned in the case, I'll think hard about installing one in my XPS Gen 3 old faithful!

  You don't have to buy a brand PNY, just because Dell sells because it doesn't mean anything. Any brand will do.  I have the EVGA 750 it. EVGA is probably the best selling partner of Nvidia.  If I bought one today, I would certainly consider getting the MSI HERE.  The reason is that the fan accelerates only execution around 32% compared to my EVGA clocked at 42%, which makes it much more quiet and nothing you can do to reduce the fixed fan speed used by the manufacturer.

  These new chips run very cool, so there is no reason to have fans operating at 42% in my opinion.  The MSI card does not require an additional power of 6-pin connection.  Some do it including the EVGA I, but this isn't really a concern.  This is only a concern for those who do not have the power on their power supply connector.

• XPS 8500 added second HDD and second optical drive

  I'll order a XPS 8500 with a HARD drive and an optical drive (at the same time TBD).  I'll add an additional HARD drive and an additional optical drive.  If I understand correctly, there one Sata3 connector which I assume is already occupied by the main HARD drive.  There should be three Sata2 connectors, one occupied by the primary optical drive.  The remaining Sata2 connectors are available for my new additions?

  What additional data / power cables will I need?

  Thank you!

  Hi Husker77,

  Welcome to the community.

  The system has two bays of 5.25 inches for loading tray SATA DVD +/-RW or Blu - ray drive (option) disc (optional) writable Blu - ray disc and two Bay 3.5 inches for SATA hard drives (internally accessible).

  An mSATA SSD drive (available internally). There are four connectors 7-pin (1 x SATA III, 3 x SATA II) where you can install the drives. A SATA 3 connector is occupied by the main hard drive and a SATA 2 connector is occupied by the optical drive. So yes, you can install a secondary hard drive and an optical drive in the system. Power connectors, ideally it should be there in the Tower system, however in case they are not present, you may need to power connectors to be ordered separately.

  Let me know any conclusions, glad to be useful.

• XPS 8500 and Windows 8.1

  In December, I improved my 8500 to 8.1 Windows XPS (I got the banner "do you want to level" within the BONE, so why not?) and about 3 days after upgrading my XPS couldn't find the HARD drive.

  After a painful 3 weeks of work with support, receiving 2 recovery USB keys and finally the DVD to reinstall the OS, drivers and software (which have all failed to recover the HARD disk) Dell's Support convinced me the problem was the 8500 with Windows 8.1 for the hybrid SSD/HDD RAID drivers (which I couldn't find any mention of in the literature of the machine when I was doing) the original purchase,...)

  Long story short: Dell Support had me reformat the disk, reinstall the OS, the data has been lost (luckily I backed up to NAS) and finally my XPS 8500 was back running with Windows 8.  I learned to avoid the upgrade to 8.1 "until drivers are available".

  Well, my support is now expired and I don't see any new drivers XPS 8500 available on the support pages.

  Has anyone successfully upgraded to WIndows 8.1 on their XPS 8500 yet?  Are you still running with the hybrid propulsion system?

  Thanks in advance!

  Greg.Fenton

  Has anyone successfully upgraded to WIndows 8.1 on their XPS 8500 yet?  Are you still running with the hybrid propulsion system?

  I've updated all the way to Windows 8.1 update 1 on my XPS 8500 (SSD/HDD + Radeon HD 7870) without any hardware problem. That said, I believe that what can happen is you install a bad driver from Windows Update or too many updates installed at the same time.

  Try this:

  -Install all the updates of Windows 8 except the 8.1 update and hardware driver updates.

  -When the above is complete, install the 8.1 update.

• What is a simple but effective update to the XPS 8500 video card? (Computer complete Newb)

  What is a simple but effective update to the XPS 8500 video card? (Computer complete Newb)

  
  Hello Dell Community. I read through the sticky XPS compatibility and some discussions on upgrading video cards. However, I couldn't find something that fits my needs. If you all can help me with this, would be great!

  Characteristics of the computer:

  • Dell Xps 8500
  • Intel Core i7-3770 CPU @ 3.40 GHZ
  • 16 GB of Ram
  • 64-bit operating system
  • AMD Radeon HD 7570

  Needs:

  • Run newer games of 2014/2015 without lag on medium to high heat (GTA V)
  • Relatively easy to install (remove some screws and paste the video card in and voila!)
  • No need to upgrade the power supply

  Budget is $ 200-250:

  • Obviously the lower the better and if need be, the budget is flexible. Depends on if the gain is important for the payment of the sum.

  Look forward to your answers!

  Thank you

  Richard

  A card that I know works is $200 would be

  EVGA GeForce GTX 960 SuperSC ACX 2.0 + 2GB GDDR5 128 bit 02 G-P4-2966-KR that it comes with a 2 X 6 pin cable 8 pin Y so the stock power should be good.

• Dell XPS 8500 needs new motherboard; All recoverable parts?

  Okay, it looks like my Dell XPS 8500 which is only 2.3 years needs a new motherboard.  I was quoted $350 to fix it (90 day warranty) by Dell.  I asked Dell how much it would cost to return the warranty once I fixed it and it is $ 200 per year.  Not sure I'll go along with this.  A local technician gave me his estimate and it's $250 parts and service which includes 90 day warranty.

  Rather than take the option repair, I think to recover the coins for my next computer purchase.  My XPS 8500 has 12 GB ddr3 sdram [1, 600 mhz (2 gb x 2) + (4 x 2 GB)] and a 2 TB hard drive and the hard disk of 1 TB (from 8000 of my XPS Studio who died after 2.5 years).  All other recoverable parts here?

  All models Dell that are compatible with the latter?  8000/8500 are no longer sold.  Dell sells XPS 8900 8900 SE using DDR4 Rams.  I don't know the compatibility of the hard drive.  Dell Outlet still sells XPS 8700 expandable up to 10 windows, which uses ddr3 chips and is is compatible with the hard disk probably.

  Should not be XPS.  Actually, I prefer not to buy another XPS because I had this terrible luck with them.  I think maybe like OptiPlex business models which can have options of compatible extension of hard drive and RAM.  Anyone direct me to the configurations of these models?  Thank you.

  Some confusion here. There is none of these models as Studio XPS 8500. Amazon is the inscription incorrectly. There's a XPS 8500.
  The 8500 XPS and Vostro 470 use same motherboards =.
  XT4TM = card mother NW73C, DPK for Windows 7

• Dell XPS 8500 scalability

  Hello

  I am wanting to maybe update the graphics card or power supply in my XPS 8500 but I want to make sure before I do it.

  Basically, I asked around on some forums and nobody seems to give me a solid and reliable response.

  I want to know is the Corsair power supplies would be compatible with my system and adjustment. Ideally, I want one that will test of the future me so I can upgrade video card in the future. that is with good connectors.

  I've been watching this Corsair power please, it'll work? and can you suggest more?

  This Corsair CX750 - http://www.amazon.co.uk/Corsair-CX750-Builder-Series-Bronze/dp/B008RJZR40/ref=sr_1_3?ie=UTF8&qid=1402292411&sr=8-3&keywords=corsair+power+supply

  Work the GS Corsair series will also be / adjustment?

  What about graphics cards

  Once again, without helpful answers to other forums,

  What are graphics cards nVidia would work in my current stock machine (I have an Intel i7 3rd gen, 8 GB of ram)

  and what card I could if I we're to upgrade to a more powerful power supply.

  Thank you

• XPS 8500 does not turn on, power supply problem

  XPS 8500 shipped on 18/01/13 so only a little more than 1 years. does illuminate, check psu and it's fine. reduce mobo or power button module. want to try to bypass the module by jumping pins on the mobo, problem is that I can't find any list of the pins for mobo or power button. Any help would be greatly appreciated since comp is barely over the years and cannot afford a new right now. Called Dell but no help it cause guaranteed missed, which took them 5 transfers and 45 minutes to tell me that :)

  If the green light on the power supply goes off, it detects an anomaly. So, it is not the power button that does not work.

  1. Visually check all ports USB for damage, misshapen or twisted for example contacts
  2. Try to turn on with nothing attached (no keyboard, no monitor, no mouse, etc.)
  3. Setting power off unplug and power button press / hold for ~ 15s open the case and carefully reconnect all RAM modules and PCI cards in their locations. Check the power cable from the power SUPPLY mobo and CPU. Cable control to all readers, video card etc... Pull the mobo battery and power press on/hold button for ~ 30, replace the battery (right-side-to the top).
  4. Check the cable to the module button before (F_PANEL connector on the mobo)
  5. Check before USB cable to motherboard
  6. Etc.

  The manual is hereif you need information about all of these connectors.

• SSD boot drive upgrade for XPS 8500

  I want to add a new SSD 128 GB as boot on my XPS 8500 drive when using my original 1 TB hard drive as a data reader.  Questions: Is there a set of instructions on how to better fulfill the new OS install and configure both hard drives?  Can I do a clean install of Win 7 using the Dell XPS 8500 Windows reinstall DVD on the new SSD? The XPS 8500 supports SATA III drives?  Thanks for any help on this.

  An additional question: the processor can be upgraded (from i5 to i7) using the motherboard the original XPS 8500?

  Hi DoctorDED,

  8 GB of memory is sufficient for a machine dedicated to the photo or video editing. However, if you run multiple applications with a lot of resources at the same time especially treatment image or video, CAD or 3D modeling (for example, Premiere Pro, Photoshop and After Effects), then you will surely be benefited by 16 GB of RAM. With more than 8 GB also comes in handy if you make heavy use of virtualization such as Microsoft Hyper-V or VMWare Workstaton tools, especially if you are running multiple operating systems simultaneously.

  Answer please if you have any other questions.

• Dell XPS 8500 - memory upgrade problems

  I bought a Dell XPS 8500 nine a couple of years.  It came with 8 GB of memory (2-4 GB DDR 3 1600).  Recently, I picked up two sticks of 8 GB, DDR-3 new, 1600.  In total, this should give me 24 GB of memory.

  Currently, housing 1 and 3 are using 4 GB sticks and slot 4 has a key of 8 GB.  If I try to stick the other stick in slot 2, the system does not start.  I assumed it was because a bad stick, so I went back to the store and I replaced it, but the problem persists.  I can get a total of 16 GB, which is recognized in the system.  According to Dell, and Crucial, this system should support up to 32 GB.

  This system only supports the memory to some total amounts, as the 16/08/32?  I checked my BIOS is updated as well.

  I'd appreciate any comments on it.  Thank you!

  If you consult the technical data sheet, the only supported RAM configs are: 2, 4, 8, 12, 16, 32 GB.

  Read this.

  EDIT: And modules are best installed in pairs, so 2 x 4 GB + 1x8GB is not an optimal config.

• XPS 8500 card video, power, upgrades

  I see several threads looking for upgrades XPS 8500 graphics card that can be used with the stock PSU 460w or improved power supply.   However, in upgrading the GPU for this machine, there are a few cards that are not compatible and will result in a black screen.    Even with a correct video card installation, an appropriate power supply and/or upgrade video card fans are going to work, but there is no video.   The problem lies in the BIOS to 8500 XPS motherboard does not recognize the video card and it is a known issue that has carried over from the XPS 8300 to the current XPS 8500.

  There was a video BIOS updates of some card manufacturers to fix this problem for some cards, but there are many old maps that do not work.  The safest bet would be to use a new card with the PCI 3.0 specifications.

  In the sticky in this forum, a link to the current Dell drivers shows the following video cards that support drivers for Windows 8:

  Video

  GeForce GT 545 | GTX660 | GTX555 | GeForce GTS450 | GeForce GTX 590 | GeForce GTX 460 | GTX680 | GeForce GTX 580. GeForce GTX 560 Ti | GTX 480 | GTX690 http://downloads-us.dell.com/FOLDER00753042M/3

  Since it's cards Dell OEM that are supported, there are also specific questions from manufacturer where a given video card model may or may not work according to its configuration.  Considering that an XFX HD 6870 will work in the XPS 8500, the same map made by another manufacturer may not work.

  Please consider this when you do upgrades of the PSU and GPU and, hopefully, BIOS upgrades in the future will answer these questions.

  It would be useful if you have a SPECIFIC card that does or does not, to indicate the manufacturer and the model number full in this thread.

  Operating system information and the Bios would be also useful, and if you use the power SUPPLY Dell or a block upgrade of power.  Specific model please!

  Edit:

  Please include following and other useful information

  Manufacturer number and model of graphics card:

  BIOS:

  Operating system:

  Power supply manufacturer otherwise Dell 460w PSU:

  Compatible: Yes or no

  Original card with the system that has worked:

  I just installed a GTX 970 in my Dell XPS 8500 with questions for the first time.

  It's pieces:

  • Updated my XPS 8500 Motherboard Bios to version "A12" while you wait for my parts arrive
  • EVGA NVIDIA GTX 970 Superclocked Graphics Card (EVGA 04 G-2974-KR)
  • EVGA SuperNOVA 750B 1 750W power supply (PSU) (110-B1-0750-VR)

  Note that I have chosen the 'Return of the fan' version of the card, rather than the version dual fan ATX 2.0.  This is because the design of the housing of the 8500 XPS is not 'Great' traffic.   The style of 'Référence' (shell solid video card with a single fan - which pulls air from the case in... and vents at the rear of the PC) is better suited to the XPS.

  

  Put a new power supply in a Dell XPS 8500 is a little something.   All ATX power supplies were about the same height and width (150mm or 5.09 ") and (86mm or 3.38").    The problem is the depth.   How deep into your PC can reach (extending to the back of your CD/DVD).   Don't forget, you have this tiny USB/headphone jack thing sunk to half way:

  

  I did some steps and realized that MAX PSU depth that would work would be approximately 165mm or about 6.5 ".     It's difficult because I wanted a 750w power supply more power and its REALLY, REALLY hard to find good food slot with less than (180 mm/7.09 "").   And who didn't come home.

  I have scoured every Watt 700 +, 80 + certified PSU carried by Newegg (from 01/12/2014).   Then, I checked cross the specs from newegg for each prospect with the manufacter to audit Web site.  I focused only on PSU at least 8 comments and then only if they have averaged a 3.5 rating (unless the low notes were for trivial things like discount).

  After having looked up the plug on more than 200 of the PSU (over a period of 5 hours), I only came with 5 potential:

  • EVGA SuperNOVA 750B 1 $69.99
  • MARINE RX-1000AE 1000W $119.99
  • SeaSonic SS - 750KM 3 750W $139.99
  • CORSAIR AX series AX760 $159.99
  • Coolmax 1200W ZPG-1200 b $282,35

  I also want to remind the reason why you MUST make sure that your power supply is 165mm or less in depth, and you can't say anything by looking at a a particular series.   Many unique models factory in a series which is just 'smaller '.   You have to look at the specifications of each individual model.

  For example, all except a psu on 700 wats EVGA are (180 mm/7.09 po).  Only 750B 1 is about 165mm.   You will also see that he is a 'Bronze' rather than 'Gold' or 'Platinum' unit 80 +.    I suspect it's "BRONZE" side has something to do with the size.   I they omitted huge heat sinks and a little efficiency to achieve the reduction of 15mm in size.   The quality of the PSU is always more than enough for my needs, and the price can not be beat.

  Now for the installation.   I won't say it was EASY to get the power supply into the case.  I had to unplug all my SATA power supply and cables.  I had to bend the cables on top of ATX case a little, and I had to be very patient reconnection.

  I also had to reroute the wire connecting the top of the case to the Mini PCI (?) card slot.   I didn't honestly it only those who were (they sit behind the rear USB sockets on the motherboard), and they snap on with small quotes as the clichés about the Jeans.  I tried to not interrupt them (because they look fragile), but I accidentally their popped.   Thank God they fix on.  There are even small arrows above each terminal (a black solid, outline to indicate white) so get back you them on in the right order.

  I found it very convenient for stuff a lot of cables in the vacuum "floppy" spot below the CD player.   I also found that I had to plug in the cables in a certain order - because some cables blocked the access to the terminals for others.   (SATA/Power to the CD player, for example is right behind UAP.  I had to do these first, because I would never get my fingers here if I saved that for the end).

  Now for the pre-installation preparation.   I updated the BIOS to A12 and downloaded the installer for the GeForce drivers before moving on my hardware.

  Driver Bios A12 two years ago, but they allowed detection of my GTX 970.  Someone asked me for the version of the drivers, so this is:

  Dell XPS 8500 / Vostro 470 system BIOS
  A12. EXE
  Release date October 29, 2013
  Last updated October 31, 2013
  Version A12

  As I said at the beginning, I was on the A09, but A12 is cumulative and takes you all the way (including all versions in the meantime).

  I uninstalled all my old ATI drivers until I stopped the first time.  I did install the Geforce drivers until after I went on my hardware.  (I wanted just the installer on my desktop - ready and waiting).

  Overall - it worked.  The map spans 2-4 "later in the case, but it fits.  The power supply is approximately 4 "away from the back of the CD, but it fits.   And it starts.

  I just finished playing "Far Cry 4' on the Nvidia setting 2560 x 1080.   The new parameter (beyond ultimate) appeared after I plugged on the map.  I also played Assassins Creed Unity (which is what I chose as my free with the card game - since I already had 4 Far Cry).   The two seem to play 60 fps with no problems.

  Because of the fan on the power SUPPLY and the evacuation from the rear video card, my machine works currently more cool now.

  Hope that helps.   My total cost was about $435.  $349 for the card and $69 for the power supply (taxes extra).

  Sincere greetings,

  Andrew Russell

  P.S. If you have questions about this weird brace to the right of the PSU...   I added a 3rd hard drive under the CD player.  There is only the 'Front holes' so I'm a little creative and put up one of the "PCI mounting plates" from an old ATX case.   I folded the right-hand curve and he the perfect length to attach as a cross tube to keep the hard drive in place.

• Conflicting responses from the Dell on Radeon HD rep 7870 GPU switch to my xps 8500!

  OK, I'm a little confused as to this what are my options. First of all, here are my PC specs:

  Dell XPS 8500

  Intel i7 3770

  GPU GeForce GT 620

  1080 p @ 60 GHz Dell moniter 24 "

  460 Watt power

  Windows 8

  1 TB HD

  As you can see a GPU upgrade is in the defined order. After some exhaustive research, through these forums and elsewhere, I came to the conclusion that an AMD Radeon HD 7870 is a level accepted for the 8500 XPS is based on the fact that it is an upgrade option during the build process when ordering as well as recommendations specific to Dell in these forums. I understand that the card requires a minimum of 500 watts and my computer only has a 460 Watt power supply. I can only speculate that Dell has tested and approved this set upwards. So, I ordered a Powercolor Radeon Hd 7870 high grade of my system.

  Here's the problem: I am concerned that the 8500 XPS accepts only HD 7870 from a manufacturer so I was chatting online with a Dell representative this morning that not only told me that the Powercolor will not work, but also, the AMD Radeon HD 7870 will not work. I'm really confused. Who is right and who is wrong. The representative of Dell, I chatted with that also informed me that food is not up-dimmable (which, I have to disagree). He also gave me a link to a generic list of the dell offers GPU on its Web site that was unnecessary.

  I need some clarification on this. At any improved successfully / unsuccessfully to either of these two GPU with a similar setup as mine?

  Any help would be greatly appreciated!

  Thanks HanoverB,

  Here is the link to the map of power supply, I ordered. www.NCIX.ca/products

  I agree with Chris M response too. All frustrated by the lack of knowledge of the other REP should have just asked in the forums instead.

  I appreciate your efforts!

  AX7870 2GBD5-2DH is a reference map of running at stock speeds and should work on the supply POWER Dell as he pulls ~ 175W of what I was able to research.

  Here is a close-up of the back of the card and Powercolor uses the PCB of the AMD, so as long as it is not a video bios problem (and there won't be that Dell supports this map of Pitcairn XT in list of Chris') it will probably work

  I would say, install it and give it a go!
