    Well DDR2 1000 at CL5 is better than DDR2 800 at CL4. That PC-8000 may do DDR2 800 CL3 at 2.2v Vdimm.

    What is the definition of "bad ram"?

    And how could one tell that their ram is bad?

    RAM upgrade

    I read your article re RAM and followed the points carefully. I have replaced the 256Mb RAM with 1 Gb from Crucial. It appears to run OK but I get several blue screen crashes. Suspect the RAM may be faulty so I downloaded Memtest ISO and burnt it onto CD. When I reboot, I get a DOS screen saying mouse driver has been installed but Memtest does not run. The screen then sits at A:\

    Hello all!

    I just installed a new mobo, RAM, and PSU in a emachines T2824 (I had the new PUS and if all else fails the RAM could be used in a new system mobo processor combo. The processor is a Celeron D 325, 2.53 GHz, 256K L2 Cache, 533MHz FSB. The new mobo is a Biostar P4M900-M4 Socket 478/FSB 800MHz with PCI-Ex16/SATA and DDR2-667. I bought (2) 1 GB sticks of Corsair DDR2 533 PC2 4200 RAM to go with the new mobo. I have it up and running with XP Pro SP2 and it seems to run fine except that with both stick of ram is it only shows 1.75GB of RAM and with only one stick in it only shows 768MB of memory, in either slot, with either stick of RAM. Any ideas? Thanks in advance!

    This is my mobo http://www.biostar.com.tw/app/en-us/mb/content.php?S_ID=283

    if you are using integrated graphics, your video "borrows" RAM.

    This is really not a running thread, it was meant to be a FAQ. Next time start a new thread. take care.

    If I remember what I read, its always best to put the same size RAM together.. (i.e: If you have 512 memory, its best to add another 512 memory, if you are going add anything. At least thats what I have read. I have 512 in my new laptop, and I have another 512 on the way for it. I am eventually gonna pull them both out and upgrade each one to 1 gig, making it a total of 2 gig. I just couldn't beat the price on the 512 memory, so I will stick that in and use it for a while.

    yes. You are only repeating my guide. Use the same brands, types, sizes, etc...

    Yeah, I read it here, and elsewhere, and it stands true. Like Tedster says, when all else fails, RTFM :D

    thanks dear for your informative response. i opened and found there are two slots, one is empty and other has one 256MB DDR PC 333 sr. no. ZHY333256RAM. The MOBO is Intel (R) Pentium 4 CPU 2.66GHZ and OS is Windows XP Mediacenter edition. Pls adv how much upgrade is possible on this set up and how much is really needed. I do not run any heavy applications on it just routing MS office work, mails, some very very basic games Does 256 mb Ram really make the system slow or the reason is elsewhere? on booting up i even get an error in MS OFFICE.EXE and low disk space warning on C drive. Does it call for re formatting also?

    Now See What You've Done.....

    Great, profound, and timeless post! Kudos!

    It can never go far enough. When I was in electronics sales I constantly muttered to myself, "just when I think I know all the answers, the customers change all the questions". Like a Mantra. Perhaps for brevities (and clarities sake) you could edit it down to "RFTB".

    Anyway, Happy New Year......!

    Please be aware I'm joking, I hope I'm laughing WITH you!

    actually my manual provided by Zenith does not give any useful specification etc. anyway,basis your helpful replies i have added today one 256mb DDR1 RAM on the 2nd slot of my comp which was having one similar RAM on it but instead of getting 512mb that i was expecting, i got 484 mb! is this OK. how do i see the difference in may have made to my system. normally i am running just basic ms office, net surfing and outlook.

    Actually, Windows 32 bit XP has an upper limit of 4GB. Since we're splitting hairs.

    I have DDR1 RAM with 4 slots of DIMM memory.
    My PC came with 512mb of memory and a year or so later i added a single sided chip of DDR ram. Those 2 worked perfectly and i hav had it since.

    A few days ago I baught anothe 1gb of ram. It is DDR 400 like the others and is double sided. I tried installing it but my pc didnt boot up. I later discovered that my motherboard cannot have 3 memory modules.

    I tried the new 1gb ram on its own and it doesnt work and with 1 of the old ones. I have tried many combinations using the four slots.

    Can you help me
    Thank you
