HP Elitebook 8540w RAM Upgrade

Hi,
I'm currently in the process of upgrading the RAM in my Elitebook 8540w. I have the Intel i7 M620 processor (dual-core) and bought the computer in August 2010. I also have Windows 7 Professional 64 bit and 2x2GB (total 4GB) of RAM.
I looked at this document to see what were the possibilities: http://www8.hp.com/h20195/v2/GetDocument.aspx?docname=c04150938&ver=25
Now, I see 2 conflicting statements in this document. On page 7, it says that 8GB modules are only compatible with quad-core processors (signified by two asterisks) and that it would only be possible to have 8Gb (2x4GB) total in my case. Then, on page 18, the table states that a 2x8GB (16GB total) configuration would be possible since there are no asterisks besides that configuration.
So which one is the maximum I can put in: 2x4GB or 2x8GB?
Thanks!
This question was solved.

Hi,
The document is for many products for the whole series. Looks like your machine is a dual core machine therefore it only it supports only 8Gb for 2 slots (the first ** indicates 8Gb each slot and for a quad core you can get up to 4 x 8Gb = 32Gb).

  • RAM upgrade on HP EliteBook 8730w

    Hi, I just bought two new hynix 4GB SODIMMs (4GB 2Rx8 PC2-6400S-666-12) and tried to install them into my laptop without luck. The computer starts with black screen and after a second or two the numlock and caps lock indicator LEDs starts to flash in blocks of three. The computer won't boot past this. From what I can gather 8GB RAM upgrade is possible and the mentioned RAM should be the correct one. Could either or both RAM sticks be faulty? Any help is greatly appreciated!

    Hi,
    Generally, it's best to upgrade memory with matching modules so a suitable upgrade can be seen on the following link.
    http://www.crucial.com/store/listparts.aspx?model=​Pavilion%20dv6-3225dx&Cat=RAM
    If your notebook already has 1 x 4Gb Module and you just wish to purchase an additional one, use an application such as CPU-Z to match the specifications to your existing memory ( check the Memory and Spd tabs ).

  • Can I change the HDD in my Elitebook 8540w to a SSD?

    Hi
    I've got a HDD that has started to make funny noises and I expect it to fail pretty soon. And while that is depressing in it's own right I feel I should do the best of the situation and and put in a fast SSD instead of the old thing. But before I go and buy the equipment I need to know that it can actually be done. I have read another thread on this forum about putting a SSD in the expansion slot (CD/DVD) but I want to replace the main HDD. So, my best guess is that it is possible but if there are any people here with experience, please guide me in how to proceed.
    I have made a backup of all my important files so really the only thing I want to do is remove my old HDD and put a new one in and then install Windows 7 from the discs that followed with the computer.
    Thank you very much for your time and help.

    Hi,
    Nothing to stop you to replace an old HDD with a faster "modern" SSD. In theory you can use ANY SDD but on the safe side please use SSD from vendor(s) who guarantees its product will work such as the following vendor:
        http://www.crucial.com/eu/upgrade/HP+-+Compaq-memo​ry/EliteBook/EliteBook+8540w+Mobile+Workstation+%2​...
    The upgrade process is very simple (I actually put one Crucial 960Gb to one of my machines today). My suggestion: before doing hardware stuff, backup all files/data and prepare for a "big bang" (in my case, I cloned my old HDD therefore very fast). Please read the following articles for more information:

    First go to the RIM web site and look to see if they have an uninstaller for the device you had.  Some times a reinstall of the application and then running the uninstaller is required for complete removal.
    If no uninstaller is available, then you will have to use Spotlight to find all items with 'Blackberry' and 'Rim' in the titles.  I would also download EasyFind and use that to locate such files.  Often it will locate items that Spotlight misses.
    Ciao.

  • HP Envy 13 1030nr. Windows 7 64-bit. RAM upgrade help.

    I just purchased a RAM upgrade for my Envy 13 and I was trying to figure out how exactly to access the memory module.  I couldn't find a youtube video for the Envy 13 and reading the maintenance manual provides only partial instructions to access the memory module.  It tells you what you need to do (Disconnect the TouchPad cable 2 from the low insertion force (LIF) connector on the system board) but not how to do it without damaging the computer.  I don't want to permanently sever a cable or anything so I'm looking for help via a link to a video or more detailed instructions on exactly how to safely access the memory module. 
    I was under the impression that this would be a quick replacement, but the more I read the manual, the more I think that this is going to be a little more complicated than opening up the bottom and removing the current RAM chip and replacing it with the one I have.  Any help would be appreciated.  Thanks!

    Here is the Manual:
    Manual
    Memory is indeed on the motherboard and getting there requires nearly complete disassembly. See Page 4-26. Not sure how this qualifies as "easy" and if you have not done this before you should get some help. And yes, keep careful track of those screws. 

  • Hard Drive and RAM upgrades for latest 15" MBP

    I'm minutes from ordering a new MBP. Only concerns are whether I get hte Apple upgrades or shop around.
    I like this Hard Drive...
    http://www.compu2000.com/index.php?l=product_detail&p=6433
    And this RAM upgrade...
    http://www.a-power.com/product-10937-311-4
    If these are equivalent to the apple options I can save hundreds and get a 320 GB drive, which will make a great portable.
    So, does my plan hold water?

    You're on your own for support when you do your own upgrades like this, but generally speaking, it works fine.
    Note that HDD is less risky than RAM. With RAM you run the risk of unstable behavior that is tougher to diagnose. That said, a quality RAM upgrade and some initial testing with any of many available tools is as good as a factory build.
    HDD upgrades are less risky, and I've upgraded (well, replaced after HDD death) ones in my MBPs many many times. I crunch my hard drives more than normal and have to generally replace them about every year. Some of the MBPs don't make this easy, and prepare to get all sorts of cozy with little 0 and 1 sized Phillips screwdrivers and some T6 as well, but it is doable (just not quite for the truly faint of heart).
    Again, you're on your own for support once you do this, so weigh that in your decision.

  • This is the regular status of the memory of my macbook pro. Do you think I need a RAM upgrade?

    Hi there,
    I'm hoping to seek the expert views of the community here.
    I have a MacBook Pro, Late 2011, 17 inch. Running latest version of Mavericks. Speed seems to have slowed somewhat, perhaps since I upgraded to Mavericks, but not certain about that. Based on my research of the Apple communities, I suspect that I may benefit from a RAM upgrade.
    Attached are a few screen shots to assist:
    Based on what I have researched in the community, the fact that I have used 3.99GB of 4.00GB, and have used 5.63GB of Virtual memory, seems to suggest to me that I have well and truly maxed out my RAM. Also there is a high number of read ins/outs (but it had been a wheile since I last did a restart on the MBP (if that has any effect on these numbers here).
    I have also read that my model of MacBook Pro is upgradeable to 16GB of RAM (2 x 8GB).
    Thoughts and views from the community would be greatly appreciated. Will additional RAM help the speed and performance of my MacBook Pro?
    Many thanks.

    More RAM is always a Prudent move...

  • Video will not play on Canvas or NTSC after RAM upgrade

    editing on a G5 v. 10.4.11, Dual 1.8 Ghz G5 with a recent upgrade to 4GB of ram. Have an AJA IO LA
    After the RAM upgrade, FCP timeline will play but video is black in the canvas and image is frozen on the NTSC. Video WILL play in Viewer but no audio.
    All cables have been checked to make sure they were put back correctly - will keep checking for errors in re-cabling computer.
    Have tried refreshing displays and other tests with displays. Any info would be greatly appreciated.
    Thanks!

    pull the ram, problem goes away? - bad ram
    you can pull 2 sticks at a time to isolate which chip it is.
    did you get it from a good source - Crucial.com is my favorite, OWC is popular too - both have lifetime warranty

  • 24" iMac (Primo 2009) strange RAM upgrade issue

    I have a 24" iMac (Primo 2009) at work. I been granted a RAM upgrade by the IT department and have received 2 indentical 4 GB modules.
    The 24" iMac (Primo 2009) uses 1066 MHz DDR3 modules and supports up to 8 GB RAM in 2 slots. I have purchased RAM from this source http://www.dustin.dk/product/5010642132/corsair-4gb-ddr3-1066mhz-1x4gb-so-dimm-i mac-macbook-macpro/#intcmp=searchProvider_SiteSeeker (Corsair Mac Memory so they SHOULD be fine.)
    Here's the issue:
    I had 2x 2GB modules. I have taken both out.
    I have inserted the new 2x 4GB modules but the machine refuses to boot. It gives off 3 beeps-interval-3 beeps-interval (repeats).
    I took out one of the 4GB modules from slot B. It boots.
    I inserted the one I removed in slot B again so we're back at 8GB. same beeps. No boot.
    I switched the 2 4GB modules from slot A+B around. Now beep-interval-beep-interval (repeats) No boot.
    I inserted one 4 GB in slot 1, and one of the old 2 GB in slot 2. It boots with 6GB RAM.
    I inerted only the one that won't boot when in slot B in slot A, beep-interval-beep-interval (repeats) No boot.
    OK - so logical deduction tells me one of the new 4GB RAM modules is defective. No matter what configuration, booting fails with that specific module inserted, though there are different beeps. I also know tha both slots work since the machine works with 6 GB RAM (2+4).
    So I called Dustin, and since we're a big customer they sent a new moduel for free. But, I have the same isssue with the new module!! What are the chances I have recived 1 working and 2 defective modules? not big right? So my iMac seems fine with the old 2GB modules and one of the new 4 GB modules, but says no to the 2 other 4GB modules.
    YES - I have tried resetting PRAM and SMC to no avail. Any clue?

    Switched the 2 modules around, so there's now a 2GB in slot A and a 4 GB in slot B. Still works fine

  • Kernel Power error after Win 7 and RAM upgrade

    Hello,
    I posted earlier on the subject of win7 and ram upgrades.  I did both and it seemed to go fine.  I did the ram first ... replaced a 667Mhz 1gb with a 800Mhz 2gb.  A couple of days later the computer just shut itself down and restarted.  Since then it has done it another 5 times, seemingly at random.  Yesterday I decided to spend some time looking into it and found the 'event log'.  All the shutdowns are recorded as 'critical'.  A search on the web/here showed other occurences of the fault associated with drivers as much as anything.
    After I did the win update I did update almost every driver with ones from this site.
    Other than the shutdowns the only issues I have which are of very mild concern are the length of time the fingerprint reader takes to be present and that occasionally the cursor is unavailable for about a minute after logging on. When you try and control it it jumps about anywhere but where you want it to go.   I rolled back the alps driver and that seems to have sorted the cursor issue.
    So, details of the shutdown from the event log are as follows.

    There's more (I've shown it all below) but it's not that important.  When I looked into it I found details of the problem on the microsoft knowledge base.  Its described here http://support.microsoft.com/kb/2028504.
    I believe I fit into scenario 3 for cause and resolution.
    So, it seems that win7 and mixed speed ram may be a problem on some computers ... probably only a tiny number, but it looks like the HP3507 is one of them.  I did see somewhere that I could down speed from 667 to 266 which might help with memory compatability but I can't see anywhere on the the insydeH20 bios where to do it.  BIOS is version F18 .... upgraded from F15 as part of the Win7/RAM ugrade.  
    Before I swap back to the 'old' memory I'll see if anybody here can come up with any ideas.  It may be that I have to sell off the expensive 2gb memory (ddr2 800mhz 200 pin) for £39.99 from maplin at a bargain price and get 2gb of 667Mhz from somewhere.
    The full 'detail' regarding the fault is below.
    Bye for now.

    Hi DWeiland and Schwede,
    Thanks for your replies. Yes I did the runtime engine registry change and also mass compiled the LV7.1 folder and my sourcecode. I still see the problem as I have set the LV adapter as Lv 7.1.1 runtime engine. Now I have changed it to LV7.1 development system. With this setting, it is not giving any error. Thus I don’t see any problem now. The older version of the code had the adapter as the runtime engine for some reason, now I have changed the setting to the development system. I hope that it shouldn’t be a problem.
    Thanks again!
    Thank you,
    Sasi

  • Mac pro 5,1 RAM Upgrade

    I am planning to give my Mac Pro (Mid 2010) another RAM upgrade. As the official Kingston/Crucial DIMMs do not include 16GB DIMMs, I think of choosing Kingston Value RAM: ECC Registered (3x, 16GB, DDR3-1600, DIMM 240). Has anyone here in the forum tried these?
    Thanks for your comments.

    The biggest official Kingston part is KTA-MP1333/8g which is a single 8GB module.
    For 16GB modules the main criteria are that
    It must be registered memory - not buffered, this is more because there aren't any 16GB buffered DIMMS
    You cannot mix registered and buffered so any other existing memory left fitted must also be registered, as it happens you are supposed to not mix 16GB with smaller sizes anyway
    It should be 1333Mhz DDR3 although in theory 1066Mhz DDR3 would work, again I don't believe there are any 16GB 1066Mhz DIMMS
    It should be ECC (error correcting)
    CL9
    The presence of a Thermal Sensor is apparently not compulsory, i.e. memory without it will work in a Mac Pro.
    I have not used any 16GB DIMMS myself but other than OWC as per the link provided by Illaass, the following might be suitable
    KVR13R9D4K4/64i - this is a kit of 4 x 16GB and this article has a post from someone who says they worked for them http://forums.macrumors.com/showthread.php?t=1493588
    If you can find a kit of 2 x 16GB of the same type then logically they should also work, they would probably be KVR13R9D4K2/32i. As a reminder to do 64GB or more you need dual processors. The single processor model Mac Pro 2010 is limited to 48GB.
    See http://www.kingston.com/datasheets/KVR13R9D4K2_32I.pdf
