memory of HP elitebook 8440p upgrade question

Hi all

I have a quick question today, in fact I have a Hp Elitebook 8440p with core i5 and 2 GB of ram (samsung 2rx8 pc3-10600).

and I am running windows 7 x 64 bit.

so I decided to upgrade memory up to 8 GB and I install 2 x 4 GB (matched pair) (hynix 1rx8 pc3-10600). but it does not work. won't start and loop. and if I put original samsung 2GB new then its job well...

I tried several times with all possible combinations, but it does not work. and if I go to the bios Setup, it shows 8 GB memory installed in it but can't get thorugh inside.

I wonder what the problem of 2rx8 and 1rx8? because my old 2rx8 obtained original and new obtained 1rx8 on that...

I'm really worried about it... Please help me soon... Thanks in advance

I can't say 100% for sure, but yes, I think that the number of chips of memory to the Board of Directors may indicate density.

The symptoms you describe indicate a problem of density to a "t".

Memory shows in the BIOS, but the PC refuses to work with her.

I suggested this to several others and cause when they bought the memory of lower density with 16 chips to the Board of Directors, their problem has been resolved.

  • EliteBook 8440p: elitebook 8440p upgrade of windows 10 mess with boot

    Hello!

    I bought a refurbished elitebook 8440p with pre-installed windows 7, 8 GB of RAM, 2.40 GHz processor.  I continued to refuse the upgrade of windows 10 when he constantly jumped upward and then one day I turned on the computer and it updated in any cases without permission.

    Since the upgrade, if I shut down my computer, or try to put in standby or Hibernate mode, when I go to wake up or put on, I always get a white screen. In general, I have to turn power several times on and off until any startup screen. Then half of the time, when I get a splash screen, my cursor is stuck at the top of the page, moving only left or right whenever I try to move it. So I have to turn and turn until a new screen is displayed.

    I studied how to remove 10 windows and reinstall windows 7. I passed the period of 10 days or 30 days. Media creation tool asks for the product key which I type in the sticker on the bottom of the laptop, but do not pass the verification process saying to contact the manufacturer for help.  Apparently there may be specific drivers or something you took when it improved and the media tool does not allow me to create anything for me to do a clean reinstall of windows 7.

    I tried to find an option after pressing esc at the f11 reset start screen. There was no option to do so. The best I could do was to 'reset' of the computer, but he took back to the original Windows that it is firstly set at level 10 to. All my files are deleted from the computer. I just want to return to Windows 7, but could not find an effective way to do it.

    Thanks for any help you can offer.

  • EliteBook 8440p: problems of Expansion RAM HP 8440p

    I recently decided to upgrade the memory on my EliteBook 8440p. After reading the form of RAM required, I bought one of these: http://www.ebuyer.com/737970-kingston-4gb-1333mhz-204-pin-cl9-ddr3-sodimm-non-ecc-unbuffered-1-5v-me...

    Once the new RAM is installed in the expansion slot, Windows will not start and crashes just on screen "starting Windows." Then I tried a test of memory using the system BIOS diagnostic tool, but the laptop either hangs around 35% (I left it there for about two hours), restarts, or stops altogether. I thought that I would give to the system try, repair tool but which caused also just the laptop restart. Curiously, when I check the "System information" tab the system diagnostics, the two RAM sticks are detected with current and accurate information.

    I contacted eBuyer, they sent a replacement out there, but I'm having the same problem again. So, I thought I would try to install new RAM in the internal slot instead (under the keyboard), but now I have a BSOD during the 'Starting Windows' screen, give me code error, "IRQL_NOT_LESS_OR_EQUAL"

    I read on some forums tech upward. One of them suggested runs what is called 'Memtest' at startup via the CD, I tried, but the laptop restarts only during the first passage of the test of memory (and of course some loops over and over again until I remove the CD).

    I'm starting to lose hope! Any help/advice/suggestions would be greatly appreciated.

  • HP EliteBook 8440p: memory modules RAM that actually work for HP EliteBook 8440p?

    Hi everyone again. I scoured these forums and others and can't find a definitive answer to the upgrade of my RAM memory.

    My system:

    HP EliteBook 8440p

    2.8 GHz Intel Core i7 M640

    Professional Win7 64 bit

    133 MHz bus clock

    BIOS: HP 68ccu, worm. F.11 (2010)

    Dual core, hyper-threaded (4)

    (?) Mobile Intel QM57 chipset

    According to Belarc Advisor, I currently have a 4MB of RAM Samsung under the keyboard module. The second location is empty.  First of all, more memory RAM is not sold in the UK? I know that the computer is capable of 8 GB and the Kingston modules, I just tried to install were 4GB each.  Sticks of Kingston are 8 GB (2 x 4), PC3-10600, CL9, 1.5V, 204 pins SODIMM modules and they do NOT work on this laptop even if they should.

    Has anyone found the secret of exactly which modules memory will work with this specific model of laptop? It is issues of density? Problems of tension? Am I missing a driver. I have to sing the thing while I install memory?

    Seriously, any help at all will be appreciated.

    Hello:

    Please read this thread, and I posted the memory you need to NewEgg if you live in the USA/Canada.

    The 8440p uses the same memory as the 6550 b.

  • EliteBook 8440p: EliteBook 8440p has no RAM 8 GB upgrade

    I have EliteBook 8440p with i7 M620, 4 GB of RAM and WIndows 7 64 bit installed.

    I wanted to update my RAM 8 GB as suggested here and bought 2 x 4 GB RAM of:

    KINGSTON ValueRAM 4 GB DDR3-1333 (PC3-10600) SDRAM-DDR3 CL9-9-9 204pin 1.5 Volt

    I replaced the 2 GB card at the back of the laptop with the Kingston 4 GB and when I started windows:

    • The BIOS showed 6 GB of RAM
    • But blocked when Windows starts, your stay at the black screen with the "starting Windows" without the points colored forming in a window.

    I tried to restart, but no change.

    No idea which can try to solve this problem, or switch to 8 GB?

  • Where are the memory slots on the HP Elitebook 8440p?

    Hello, I have a HP EliteBook 8440p, with serial number: {deleted personal information} and the product number: SK119UC #ABA

    I have 2 memory slots. 2x2gb for a total of 4 GB of system memory. I found one of the memory slots on the bottom of the laptop (there was a small picture of a ramstick). I would like to find another, but I don't know where he is, so I ask help on localization.

  • EliteBook 8440p; DM1-3020us: 2x4gb 1600 MHz DDR3L works in Pavilion DM1 but not Elitebook 8440p? But both are supported than 1066 MHz RAM

    I have two Elitebook 8440p PCs that both run an Intel i5 520 m (although one of them has a discreet Nvidia NVS 3100 m, while the other does not and use the integrated graphics card Intel).

    I also have a Pavilion DM1-3020us with an AMD E-350 APU; It's the only other PC I own which takes SO-DIMM DDR3 modules.

    I just bought this Crucial DDR3L 1600 MHz 2x4gb hoping to use it with the 8440p without the graphics from Nvidia:

    http://www.BestBuy.com/site/crucial-2-Pack-4GB-1-6GHz-PC3-12800-DDR3L-so-DIMM-Unbuffered-non-ECC-lap...

    However, it causes crashes and BSOD as soon as he tried to start under Win7 64 bit on both 8440 p PCs.  Also when trying to boot Linux Mint 18 I empty a kernel panic, and run Memtest86 + just leads to restarting the PC within seconds.  Yet, I can navigate through the BIOS throughout the day and it will continue to work very well...

    But here's where it gets really weird - the RAM works perfectly fine in my laptop DM1 Memtest86 + and Win7 64 bit (I use it as I type this).  What's curious?  Because both the AMD E-350 and the Intel i5 520 m only support up to 1066 MHz RAM!

    The only thing I can think is that there is something wacky where RAM is unable to operate at 1066 MHz at 1.5V or is not able to run at 1.5V to all E-350 1.35v support (and 1.5V RAM so that the i5 520 m only supports 1.5V) which itself would be really strange that Micron (which actually manufactured the RAM) States on their website that their 1.35v and 1.5V RAM have actually the same die (a bit like mobile i7s quad vs quad I5S Office) and that both can operate at 1, 5V, implying therefore that the 1.35v product is simply a higher binning:

    https://www.micron.com/~/Media/documents/products/technical-note/DRAM/tn4114_ddr3_1_35v_1_5v_compat...

    Crucial live chat support, however, closed several hours for the day, so I thought I would at least make this post in the meantime.

    Hello:

    Please see this thread, and the discussion that I posted in this thread... and you'll have your answer.

    6550 b has the same chipset as the 8440p.  I posted the link to the site from NewEgg for the memory, you need to buy if you live in the USA/Canada in the discussion that I've referenced to the other person who had the 8440p.

    http://h30434.www3.HP.com/T5/notebook-hardware-and-upgrade-questions/RAM-memory-modules-that-actually-work-for-HP-EliteBook-8440p/m-p/5570634#M335108

    There are several discussions on this issue if you want to find even more.  Everything is solved by specific G.Skill memory I posted.

    The extent of why it works in the dm1 and not the 8440p, the chipsets are different.  The Intel chipset in the 8440p doesn't support voltage DDR3L.  Comparison of AMD and Intel chipsets are like comparing apples and oranges.

    I also believe that the chipset amd in the dm1 is more recent than the chipset in the 8440p and promotes low-voltage memory.

    I have just return from memory and use the gift card on something else.

    I doubt that Best Buy has this specific memory.

  • HP Elitebook 8440p WWindows7

    Hi I have a question, got this laptop (HP Elitebook 8440p) last month it came with 320 GB HD, 3 GB of RAM and Windows 7 Pro 32 bit installed (I also drive original windows 7 32 bit Pro that comes with it). Now, I intend to upgrade the RAM 8 GB, replace with a 128 GB Samsung SSD HD and install Windows 7 Pro 64 bit.

    My question is can I use the product key on the underside of the laptop for the installation of 64-bit?

    I phoned and asked HP, but I was told that it is not possible that the below key is useless without the original hp windows disc 7 with that he came.

    Hello:

    This is not true.

    But why not order a set of recovery disc from HP for $10? Then you don't need the product key.

    Tell them you want the floppy drive of W7 Pro 64 bit recovery game. That's what I did with my HP 6930p.

    Mine came with 32 bit also and I wanted maximum memory of 8 GB, but only had a 32-bit recovery DVDs.

    Call HP at 1-800-334-5144.

    Only, you must also provide the serial number of your PC.

    If you don't want to spend $10, then everything just this...

    If you can read the Microsoft windows 7 25-character product key, you can download simple Windows 7 ISO files to burn on a DVD for the version of windows that is installed on your PC, and which is listed on the Microsoft COA sticker on your PC case.

    Burn the ISO with the option to burn the ISO on your DVD burning program and burn it at the slowest possible speed that will allow your program. This will create a bootable DVD.

    Use 25 characters on the PC product key to activate the installation.

    The key will activate a 32 or 64 bit installation.

    Then go to the support of the PC and driver page to install the drivers you need.

    Link to downloads ISO of W7 is below.

  • Maximum supported size of HARD drive for HP Elitebook 8440p Windows 7 Pro 64 bit runing

    Hello, I just bought a HP Elitebook 8440p "off lease" of Tigerdirect and seeks to upgrade the two memory (from 4 GB to 8 GB) and put in the eligible of the biggest HARD drive I can. Either a 512 GB SSD or a 1 TB WD hybrid WD BLACK2 (1 TB HDD / 120 GB SSD Combo drive in a single package!). I would like to see more large disk addressable by using Windows 7 Pro 64 Bit OS since I don't seem able to find this info on the web. HP offers only only a 256 GB SSD in its specifications. but I didn't know if it was do limitations of BIOS or availability at the time of production, even for the HARD drive to 512 GB.

    Also, I would like to know if 9.5 mm compliant Bay that it needs to be for the WD drive. Can't find that either, and while the new laptop has not yet happen, all measure exactly the same way regarding what works and what simply cannot be "cheated".

    Thank you for taking the time to read this and NO information to that effect would be Greatl appreciated!

    Essentially the reason why you do not have a maximum size of hard drive is because there is not everything. Between SATA and 64-bit OS', worrying about maximum size of hard drive is a thing of the past. Are the biggest readers found in the manual, as you suspected him, just a function of the market at the time of manufacture. It was a few years ago now, it is so understandable that the offerings were "at the time" more thin than now.

    Here is the Service Manual:

    Manual

    Page 4-9 shows the procedure of the Bay and the replacement of the hard disk. The Bay is made for a 9.5 mm thickness 2.5-inch wide SATA hard but the new 7 mm readers also works. The black hybrid drive requires some software (included in the package) to treat the two drives in Windows and I read a modest amount of disappointment in the documentation about them. If you can afford the 512 GB SSD go in this direction and you will not be sorry. I use a Samsung 840 Evo and it has worked perfectly for me for almost 2 years and the most recent 850 I hear is even better.

    Hi @danielqk ,

    Thank you for visiting the Forums HP's Support and welcome. I looked in your question about your 8440p and problems with start-up Elitebook. You get the error message is a hard drive error. Means that the hard drive has failed.

    If the computer is out of warranty, most computer stores can help you select a replacement hard drive.

  • HP ELITEBOOK 8440p: operating system

    Hi guys

    I need an OS to my twowarcash computer hand laptop hp elitebook 8440p and is there a free download of this out there? THX

    Jjay00507

    The answer to your question is - MAYBE!

    That the PC is preinstalled with Win7 or Vista, and go do an install of OS would be buying HP recovery media to restore to the factory settings.  It's not FREE, but it is much less than the US $100 or you would have to pay to buy a copy of Win7.

    Two problems with this good (that's what makes this a maybe):

    (1) version of the OS

    (2) availability of the recovery media

    (1) that the PC came with Enterprise, Pro and Home Basic to Win7 - and given that activation is version-specific, you need to restore using the same version.  This info should be on the COA sticker on the laptop.

    (2) HP is no longer a recovery media stocks for the Win7 PC, so a couple of other sites that you can visit are: http://www.computersurgeons.com/ and http://www.restoredisks.com/

    Yet once again, that the media is not free, but the cost is far less than buying a copy retail.

    As for free - technically, Win10 is not free; Instead, it can be activated from an existing version of Win7, 8, 8.1 - if you need runtime access to a PC with one of these versions of OS to work in order to use Win10.

    Good luck
