    Help for you, with RAM, Here!

    Are you considering more RAM ??
    Edited...When thinking about more RAM (memory) I can not stress enough that putting any old stick of RAM in your PC is "BAD" you should / must, get matched RAM to your motherboard (MoBo)

    If more than one stick of ram is to be used then go with "MATCHED PAIRS" and sell your old RAM

    Are you considering more RAM ??

    To Help Find The Right Module for Your System>>.

    Well, if you are then you need to mach it to your motherboard (MoBo), because not any old sick of RAM will do.

    I suggest that you use a RAM manufacturers web site to help you choose and if you are unsure of the results Register yourself so you can post in the manufacturers forums use the forum and ask Questions there.

    Don't expect an instant result from the forum, make a note of the link/url where your post is, use your "User CP" after logging in to set up an E-mail with a page link to be sent to you when replies have been added / threaded to your post.

    Give only the information of the hardware you are going to put the RAM sticks in,
    "DON'T" buy RAM and put it into a different MOBO.

    This is Corsairs link where you put in your system information etc. and Corsair gives you the correct RAM for your rig.

    I like Corsair hence this post.
    There are other manufacturers of course and bright sparks may add them to this post.

    When fitting RAM to your MoBo (motherboard) check with your MoBo manufacturers hand book where / which slots to put your multiple RAM sticks (not any hole/slot will do)

    For those of You with 4 sticks of RAM Look
    !

    This is a "possible" explanation of why you "may" be getting issues if your PC has 4 sticks of RAM in it and why I have said in the past a single stick or a "matched pair" of RAM is the way to go. Plz look at the answer.

    Question from snagy....
    "I currently have the TWINXP1024-3200XL (2x512) in my system and would like to add another 1gig. My question is do I have to purchase another identical set of the above mentioned or is there other options available to me?

    I saw in the pdf file that Corsair shows my setup with the addition of 2 other memory chips installed. There is no need for an additional pair of LED's, I just need the modules. Thanks".

    Answer from RAM GUY Corsairs Number 1 forum Guru
    You could add a pair of Twinx1024-3200XL Modules, but I would not suggest it for few reasons.
    1. With 4 modules you may be limited to DDR333 and you will have to relax the timings to make your system stable.
    2. There is more loading on the memory controller and with 4 modules you would need to figure about 48 Watts just for memory so you may need to have a bigger PSU.
    3. We have never suggested using 4 modules in any system especially if you are over clocking. Many MB's just will not perform well when you have the fully loaded.
    4. That picture was just an example to show the size of the modules not to suggest you should run 4 modules.

    How do you change the BIOS settings for RAM
    This is a link to a guru bios set up ...... http://www.rojakpot.com/default.aspx?location=9

    You get into BIOS by tapping "Delete" constantly when PC starts up.
    Then make a list of all the bios settings that are set for your PC. >>
    Exit with out altering anything >>
    Go to this site http://www.rojakpot.com/default.aspx?location=9 and check read the \ bios>.
    Check for the "Bios titles" (headings) that are in your PC, against the ones in the above link>>.
    Right down the advised Bios settings suggested in rojakpots link, next to the ones you have written down, ("what they should be" advised from rojakpot link).
    Go back into BIOs and change,.... save changes and exit.

    Things you should know about when setting BIOS and RAM timings.
    When tampering with Bios and RAM timings IMHO you should "read up loads" "and" "print off" the information to what you are going to do.
    If when setting your RAM timings your PC dose not post (start up before going into windows)
    you can turn your pc off at the on off button then at the back of your PC case, turn off the "main power switch" leave off for 2 minuets and turn on main power switch then on / off button your PC should then post but to basic post in Bios. then go into bios as it is posting and alter the timings again until you get it stable to what you want.
    Find out how to recover from a "none posting PC".
    Find out how to clear "comos".
    Find out how to install an up to date BIOS.

    You can get "Unmodified Content" errors if you have a faulty stick of RAM.
    To test your RAM, to see if it is registering and working correctly, run "Memtest" on one or all sticks as they are now in your PC "then" take out "all" sticks and place one stick only (in the correct slot as per MoBo handbook) and "Memtest" test again for errors.

      I don't have matched RAM and I'm fine.

        I have matched, but at different timings, so i guess they aren't matched. I have a 1 GB stick of Corsair Value Select at 3-3-3-5 and then 2x 512 MB sticks at 2.5-3-3-5.

          I think it's cool of you to make this post GreatWhiteShark. Respect.

          His recommendation about matching DIMMS is the accepted general rule. As is the case with all PC performance and stability issues, your mileage will vary.

          I've been able to run 4x512MB with a matched pair and two other similar DIMMs. I had to tweak a bit to get it up to performance but the average user won't go through the trouble.

          His guide helps many avoid the often unknown pitfalls of upgrading RAM.

          Would you do me a favor and look to see if your memory is running at a 1T or 2T Command Rate? Everest Home Edition or CPU-Z will tell you.

                  Yep, a bit like this one m8, but i've added some stuff from my answers to others that keep getting asked, sort of bunched it together.
                  I can never find or remember what I said. One its for me so i don't have to spend all day looking for it. Two, to stop my small amount of grey matter (brains) from wearing out. Three, it's is like Shamus says so eloquently

                    Well, it means that the memory controller reverted the Command Rate from one clock cycle to two clock cycles before it executes. It does have some performance impact on AMD based systems but Intel systems default to 2T.

                    What does moving down to a 2T Command Rate mean for performance in BF2? In my extensive testing, I had to lower the speed to 333Mhz and loosen the timings while operating 2 GB on my ASUS A8V Deluxe and 3500+ Newcastle.

                    The performance difference between running BF2 using 1GB Corsair XL at 400Mhz at 2225 1T or 2GB at 333Mhz at 2336 2T resulted in an averaged increase of 12 fps using the 2GB configuration.

                    The Fraps log doesn't lie and I was suprised by my findings in that I actually got a performance increase considering I am using an aging 9700 Pro OC 411/333.
