Trying to install new ram, conflict with video card

I purchased a new stick of ram to put into my computer (motherboard is ASRock AM2NF4G-SATA2) as I only had 2gb in before (bought another 1gb...there are 4 slots). I plugged it in, it read it just fine (said 3gb), but there seems to be some issue with the video card, it would no longer recognize my video card, and I couldn`t select the proper resolution, I tried reinstalling drivers for it, but it said it was the wrong hardware (video card is PNY GeForce 210 PCIe 2.0). I shut my computer down and removed one of the sticks, and I turned it back on and it was fine. What is this issue here?

Sounds like your dimm slots need to have matched pairs of RAM installed in each slot. In my case with my old 32 bit system I had 4 slots as well. I had two 1 GB and 2 512 GB sticks installed to achieve my 3 GB total. Check with your mobo maker and see what there recommendations are for installing RAM.

Here is a screenshot of the ram:



I have another of the Kingston RAM (same as the one in there), but I pulled it and it's working fine, not sure if it matters or not.

Here is the motherboard:

That's your problem is your trying to run different speeds and timing Ram. Mixing and mismatching Ram will only cause you problems...

Fortunately, RAM is dirt cheap these days. If you can't get another stick exactly like the one you just added, I would replace them both. Even though it looks like your board has four slots I would not try to leave the old stick in there - you'll just end up with the same problem.

I'd check with the motherboard manufacturer to be sure about compatibility, but something like this looks like it would do the trick. (Assuming SIW is accurate.)

Well I already had 2 of the Kingstons (the one in the screen shot) and just purchased one of the PNY. When I put any combination of 2 sticks in, it works fine, when all 3 are in, that's when I get my problem.
