Not sure what ram I need to buy

I have an ASRock motherboard it's the P4VM800

Link to mobo: http://www.newegg.com/Product/Product.asp?Item=N82E16813157079

What ram should I upgrade too? I'd like to buy 1 stick of 1gb of ram but I'm not sure what brand and specs I should get? I'd plan on buying another 1gb stick next month when I can afford to. This is for a gaming computer so I'd like to get something that would help out in that department.

I have a Pentium 4 3.4GHZ processor on that board and I just ordered a 7800GS video card to upgrade my older card. So I thought I should upgrade the ram while I'm at it, current ram is 333 ram and not the 400 and I have two 512mb stick of it installed.


Hope that makes sense :? trying my best with this PC mumbo jumbo stuff and I'm pretty lost so feel free ot make fun :( .

  1. You have PC 2700 memory. The standard memory for your board is PC 3200. It should have capability of PC 4000, though you should check the manual to make sure. You may have to manually set the BIOS to get DDR 400 speed (PC 3200) or above. If you get new memory, be sure to get a 1 gig stick for better a upgrade path in the future.
  2. The memory description in my motherboards guide is confusing for me.. Here's what it says exactly:


    -----------------------------------------
    2 DDR DIMM Slots: DDR1 and DDR2
    1 DDR DIMM Slot Supports PC3200 (DDR400) Max. 1GB,
    2 DDR DIMM Slots Supports PC2700 (DDR333)/
    PC2100 (DDR266), Max. 2GB
    -----------------------------------------


    I don't see where it lists the PC4000 so I'm assuming that won't work? Also, will 2 x 1GB sticks of DDR 400 even work? After reading the memory description it looks like I can only run DDR333 if I want 2gb's total?

    Let me know if I'm wrong, I guess the description doesn't make much sense to me.

    I checked also the manual and i got that impression too. If you want 2GB you must install PC2700 modules.
    If you have the chance, i think you should try to install PC3200 and see if it works well. Probably it won't damage anything.
  4. Ok, it looks like your motherboard is set for older memory types. It can take 1 gig of PC 3200 memory, but it clocks it down to PC 2700 if two gig are installed. So, the best would either be to get 1 gig of PC 3200 or 2 gig of PC 2700. Since you want to upgrade to 2 gig, you might look at Kingston KVR333X64C25/1G, Corsair CM72SD1024RLP 2700, or Patriot PSD1G333H. Hope this helps.

    Installing 2 gig of PC 3200 won't hurt anything, but it just won't just to max speed. The advantage of PC 3200 is if you put in a motherboard later that can use it.
  5. Hmmm okay. I think I'll run 1GB stick of PC 3200 for now then. And if I feel the need/have the need for additional ram in the future I'll just opt out for a better board that supports 3200 on both or more slots.

    I'm guessing 1 GB of PC3200 is probably plenty for a PC gamer isn't it? I have a pretty good video card and a pretty good CPU to support it... so I'm hopinh for positive results when I get to the gaming!

    Anyway, thanks for the info certainly clued me in to what I need and what I can or cannot do.
  6. 1 gig of PC 3200 with fast timings would probably be a lot better than 2 gig of PC 2700. The upgrade path is a lot better too if you decide for a better mobo. If going to 3200, I'd suggest Corsair XMS CMX1024-3200C2PT. It offers a 2-3-2-6 timing, which is pretty fast.

    I plan on ordering a stick next week when I get my check!

    After I get the 1gb stick of DDR400 installed is it a bad idea/impossible to leave a 512mb stick of PC 2700 in the second DDR slot on my board?
  8. Leaving in the stick of 2700 is at best a bad idea, at worst, terrible. It can range from either dragging down the 3200 stick to 2700 levels or not recognizing the 3200 stick at all, to refusing to boot entirely.

    Well then I'll be ripping the 2700's out later next week when the good ram shows up. I'll put them in my linux box I'm building for website design and will use for my gaming servers I cpanel/FTP to many times daily.

    It's good thing I registered here and asked I'd either have the wrong ram or the right ram running at the wrong speed :oops:

    Thanks again.
