HP Compaq dc7700 SFF PC can be upgraded to support a 2.66 GHz Intel Core2Duo (E7300) processor?

My HP Compaq dc7700 desktop PC small form factor is equipped with a processor replacement of Intel Core2Duo 2.66 GHz (E7300), Stepping/CPU ID 10676, but I now have a start-up error message: "1801 - Microcode patch error.»  Missing or not valid processor updated Microcode.  "Please contact Hewlett - Packard Company for a new firmware update to support the new processor Stepping.

(The computer start in pressing 'F1', but performance deteriorated due to invalid processor Microcode Update).

I sent to HP, but have yet to receive an answer.   (They may have bigger problems right now!)

The HP documentation for the dc7700 is ambiguous about whether if an E7300 processor would be sustained.  In this regard, the documentation recommends against editing processors more than 95W, but the E7300 is only a 65W processor (exactly the same as the original processor E6300).

I've updated the PC system BIOS (786E1, Rev 1.16, the most recent available on the HP relevant support Web page):

http://h20000.www2.HP.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=en & cc = us & prodNameId = 3232108 &...

"(mais malheureusement, il semble que Rev 1.16 n'inclut pas une mise à jour de Microcode valide pour le processeur E7300)."

It seems that I may need to wait and hope that HP will issue a valid and new Update Microcode for the E7300 dc7700 support page.  (With luck, the update of firmware would be included in an update of the BIOS which can be implemented through the windows, not via a legacy floppy!) 

(I note that Intel provides an easy firmware update, but it is not easy for those who are running a Linux Enterprise operating system.  I am running Windows Vista Business 64-bit).

This is my first post.  Thanks for all the tips on the problem that I outlined above.

Thank you Paul and Frank,

The evidence you presented against compatibility has begun to address substantial.

Furthermore, it is probably not conclusive in itself, but Intel motherboards with a chipset Q965 (at least the names of the Council containing the string '965') also do not appear to support beyond E6700 processors...

I'd be happy to call my request 'resolved' - has answered in the negative.   Thanks again and well done! to each of you.

With gratitude,

Robert...

  • Compaq dc7700 sff: motherboards latest include the compaq dc7700 sff case?

    I want to use the case of an old dc7700 sff, but the layout of the Panel back looks like it is the inverse of all the motherboards I've found. Is there any motherboards that support DDR3 RAM and have at least three connectors SATA (SATA 3 preference) that will be adapted to this case (PCI ports on the left instead of right of ports)?

    Hello:

    Unfortunately, there is not.

    The dc7700 was the last model that used the case that has also been used d530, dc7100, dc7600.

    When the dc7800 came out, they used a completely different case, which was also used on the dc7900.

    Then the case was changed again when the 8xxx models Elite have been introduced.

    The first business office of HP in this class that came with sata ports 3 was the 8200 Elite SFF/CMT.

    Hello

    I'm sorry, but you cannot use the Core i5 - 2540M. You must use the processor Core i5 - 480 M. Some laptops series G6 such as ones of G6-1200 use chips from the second generation, so the manual you have is a general for all laptops to G6. The first generation Intel processors use a different socket than the second. A possible compatibility for Intel processors is when you have an Ivy Bridge chipset third generation) and you can use a Sandy Bridge CPU (2nd generation)...

  • Compaq Presario CQ56-115DX: can I upgrade to Windows 10?

    I have a laptop Presario CQ56-115DX, bought October 2010 (5.5 years) and running Windows 7. Considering the free update of Windows 10, I am concerned about the graphics card (ATI Mobility Radeon HD4250). I can't find an answer consistent and simple as to if it will work with Windows 10. Some sources claim a flat No., while others say No Problem, and still others say it's possible, but I'll have to pass through many creoles, manual installation of upgrades/downgrades of device drivers before, during and after the upgrade of the OS.  Maybe a BIOS update, too.

    So, can someone give me the history of right? When all is said and done, I at least will be no worse off as I am today on Windows 7, for graphics and video capabilities? I do more than very light animation and card games - no heavy action or stuff VR Council. This laptop has the power to do this kind of things anyway. If there is clear instructions somewhere for the manual steps that must be done before pulling the trigger on the upgrade of Win10, I can follow them. I don't want to risk in bricks during the upgrade! Supposedly, for 30 days after the upgrade, I can return to Windows 7, but it's no good if I can't get on the machine in the first place.

    I realize that this machine is getting quite long in the tooth, so a hardware upgrade (if that's even possible) is out of the question. If I have to stay on Windows 7, I'll run that, until the support is gone and then switch to Linux or something (maybe dual boot) until the material finally die.

    Are there any other known folds in a Windows 10 upgrade, in addition to the graphics? I've seen complaints about wireless, keyboards, optical drives and other things does not work properly after the upgrade.

    PPerry57

    My advice, after these uprades and seen THEM fail miserably on the old PC (like yours) are NOT to do the upgrade.

    Sorry to be the bearer of bad news, but the problem, that you are facing is that Microsoft provides only pilots with the most basic features and what you really need for these features in laptops is the specialized drivers written for the specific material found in laptops - and unfortunately, there is no HP Win10 laptop driver.  HP only guarantees the compatibility of Win10 for machines manufactured after August 2013. HP is not no matter what timetable indicating when, or IF, they will produce drivers for older machines.

    This means that your PC is probably NEVER going to be fully functional under Win10 because the pilots is needs for all features simply do not exist!

    Also, there is no upgrade for the BIOS of your PC because it has not been compiled with Win10 in mind.

    While Microsoft tells you there is no risk in the upgrade of Win10, because they allow you to believe that you can always return to your BONES and the original installation program within 30 days, the ugly faction of the matter is that the Win10 GoBack feature turned out to be unreliable - and when it fails it can leave machinery in a State corrupted - that does not always happen , but it happens often enough to be a problem and you will get no warning beforehand that he goes to the trash your PC!

    Thus, people who tell you that you are no worse off the power if you upgrade to level do not take account of the reality of the situation - you'll be no better off and will be certainly less well off, how much, nobody knows.

    However, if you are willing to do some work and are determined to try to upgrade, then read on...

    You think about the amount of work that you want to post just to run Win10.  Seriously.  Old machine Win7 tend to come in two flavors when it comes to upgrading Win10 - really easy and really difficult.

    The really hard to upgrade computers fall into two categories: (1) those who are expandable to Win10 and works OK, (2) those who are not.

    Computers laptops HP, especially old Win7 machines, often came with two different graphics - and Intel chips and then either a processor AMD or Nvidia.  This was known as switchable graphics card or hybrid.  You have run using the Intel chip most of the time, but when you need additional graphics power, as in the game, the PC automatically switched over to the use of the AMD or Nvidia graphics chip.

    Problem is, this requires special graphics drivers to work, and while that those that are preinstalled on laptops Win7, these drivers simply do not exist for Win10.  These drivers are not available from Intel, AMD or Nvidia.  One way to tell if your PC has two different graphics chips is to look in under Graphics Device Manager.  If there are two different cards in the list, an Intel and AMD/Nividia, then you have this problem - and if you force an upgrade to Win10, you will have serious graphic problems and your machine will not work.

    However, if you do not have this problem, to CAN pass to Win10, but you must be willing to do four things:
    (1) do a full image backup of disk external drive or USB stick, capacity
    (2) changes to the reserved system partitioning hard disk recommandΘes mΘthodes,
    (3) use a different approach and maybe more than one, as Windows Update to do the upgrade,
    (4) prepare for a clean install.

    ---------------------------------
    1: backup of images:
    This is VITAL, because the machine is doomed to failure of the upgrade, and when that happens, you will learn that GoBack to Win10 function is NOT reliable, and that can leave you with a corrupt machine that will require the factory reset and lose all that on it, to get it working again.

    You can avoid this by making an image backup to an external hard drive or a USB drive using Macrium reflect (MR), which provides a FREE version that can be used to image and restore partitions or drives together.

    What I recommend is the following:
    (1) download and install Macrium reflect (MR)
    (2) run M. and choose the option: "Create an image of the partition (s) required to backup and restore Windows" to write a full backup to an external drive or USB key
    (3) use the option to create a CD or a USB startup key

    NOW, you have the means to restore a full system that works for the external hard drive or USB key in a few minutes.
    ---------------------------------
    2: System reserved for resizing:
    There is a small partition on the HDD with Win7 preinstalled machines known as system reserved.  It is something known as the boot loader code.  There is 100 MB format: all that is necessary for Win7.  But Win10 needs 350 MB and, in some cases, is NOT able to resize it on its own.  IF this happens, you must manually use a partitioning tool to resize it yourself.
    ---------------------------------
    3: use a different approach to upgrade:
    Windows Update is the simpler, but less reliable, way to do the upgrade from Win10.  A much better and more reliable way is to use Microsoft Media creation tool: http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install?ocid=ms_wol_win10 choose the upgrade this option now PC.

    After all this, you know that MS install drivers with only the most basic features.  Given that HP does not have drivers for your PC Win10, this limited functionality is the best you're going to get.  HP does not actively write new drivers from Win10 for the old PC Win7.  To keep all the features of your PC, your best shot is NOT to upgrade to Win10.
    ---------------------------------
    4: be prepared to clean-install:
    If you do all this, and after the upgrade, your PC works partially, this means that the upgrade is not well and stuff is still there the previous OS corrupt the functionality of Win10.

    You MIGHT be able to solve the problem in fact a clean install of Win10. Problem is that, often, a clean-install does not recognize prior activation, even if it should. So, before doing the upgrade, follow these instructions on the community forums Win10 on creating a genuineticket.xml file: http://www.tenforums.com/tutorials/23354-clean-install-windows-10-directly-without-having-upgrade-first.html

    You need more later to activate your pc Win10 after the installation of clean.

    -----------------------------------------------

    Good luck

  • HP Compaq DC5850-SFF: Why can I not overclock my processor?

    Hello. I have purchaced a 9600 B AMD Phenom Quad-Core CPU. Everyone can overclock, but I can't. My motherboard is an HP 3029 H. So could someone let me know why I can't overclock, would be great. Thank you for your time.

    (PS) I tried several overclocking programs, even those made by AMD.

    Hello

    It is locked in the BIOS. If you want to overclock build your own machine, do not use the machines of the brand. Reason: overclock machine will generate more heat and can fried a machine at any time. No seller would send customers machines returning due to lack of material.

    Hope it makes sense.

  • Can I run After Effects with 2.4 GHZ Quad Core i7 Processor, 16 GB of RAM and a new SSD hard drive?

    I have a 2011 Mac Book Pro with 8 GB of RAM and The RAM Preview plays in 10 second Incraments. I want to pull out my hair! I don't have the sum of $ to buy a new computer. If I switch to 16 GB of RAM and get a new drive SSD will work After Effects, or I lose my $$. Please help, I have a very important project. It is about 12 minutes long and I need to add a lot of sequelae to complete my project

    First of all, you have optimized your system: Optimizing after effects of performance - Support Adobe

    Second, it looks like you are fairly new to AE and that your workflow is not very effective. Here's the deal. After effects is not an editing application, it is a graphics and compositing designed app to create shots or short sequences. In addition, I would say that more than 90% of my AE projects are less than 10 seconds, because I created shots (with handles - extra images) I'll change in the body or some other NLE. Some of these comps second 10 have a hundred layers or more. If I had to do 12 minutes into a movie I would fuck the cut first in Premiere Pro to understand what was the best way to tell the story, then each shot than necessary effects would become a separate AE comp. At the very least each scene must be a model. In most of the stories that are told, as a film, a scene are only a minute or two. The average is probably less than 6 seconds. I can't imagine putting together 12 minutes in a single model AE, not because I couldn't, but because I would probably change the "timing" of some of the cuts, edit audio or make some other change before I made and changes in the middle of a project of 12 minutes would be a nightmare.

    Here's how a work on almost all editing projects.

    • First installation in a NLE such as Premiere Pro until the story is logical
    • Put the shots in AE requiring animation or effects
    • Inside AE, I first make a test pencil to check the overview and animation timings with the Panel of the model to 50% or even 25%, and automatic resolution scheduled to ensure that the timing is ok
    • Effects are added and critical frames are checked 100% for color and everything else but I rarely to ram preview several frames because I'm already happy with the calendar
    • The model is sent to the SOUL (Media Encoder) or sometimes the cue to render to render in a production format appropriate (usually 10-bit or better, often a sequence of images)
    • If the model is sent to the SOUL I continue to work on the next shot until I finished all the effects work
    • The effects of rendering images are reduced in the NLE to replace shots in the rough cut and editing is polite
    • The project is then added to the hearing for the final mix
    • The final color ranking is made - usually in the category of speed or resolution
    • The final product is made to a production for archiving format and a format of distribution (usually h.264 mp4)

    There are a lot of bounce back, but it's the most effective way to work on any project. Have you noticed that an overview of full resolution RAM full length does not at any time?

    If installation requires only a few short shots or sequences to AE, I will occasionally use Dynamic Link, but most of the time all the effects work is made. It just makes it much more efficient.

    I hope this helps.

  • DC7700 SFF BIOS support

    My father has just bought a PC HP Compaq DC7700 SFF (Small Form Factor) used and refurbished and we get an error whenever the computer places.  It reads "BIOS ME Extension stopped Module.  I did some research on Google, and it seems that the error indicates that the BIOS and the BIOS Extension ME are out of sync, which means that their versions do not match.  We are a bit surprised, it was not addressed prior to packaging for resale upward, but nevertheless we are here.  The computer came with Windows 7 Home Premum 64 - Bit.  It is the source of the problems.  Everything I read says to use a BACK program called "FlashBin" to Flash the BIOS with the latest version.  Whenever we try to run the program, it errors saying incompatile architecture (he wants to x 86).  We tried other things is manually creating a BOOT partition on a USB Flash drive and try to run the program to start BACK, but it does not, saying no found BOOTMGR or something.  Another option I found is that the BIOS has a setting called something like "Flash BIOS update" and asked where to find the file. CD-ROM or USB.  When we put on the USB flash utility, BIOS indicates the key USB is corrupted or damaged.  This also happens when we just updated BIOS. BIN file on the USB key with nothing else.

    We are really lost here.  As I said, this is a factory refurbished PC and we would really like to get this annoying error message to go outside every time we start.  Can someone help me please?  Thank you!

    Hello:

    You can read some of the posts offered on reset the cmos on your PC.

    Reset the cmos works the same on the dc7700.

    If you want to try the update the ME firmware suggestions, you must use the files to download on the dc7700 under section BIOS support page and I wouldn't update the firmware if you have to do in Windows for the same reason that you would not run an update of the BIOS under Windows.

    I hope that the reset cmos will work for you.

    I have never had this problem on any of my dc7xxx as PC, if unfortunately I won't be able to help you with specific measures to be taken regarding the update the firmware.
