RAM help - new RAM freezes my system?

So I bought two new RAM sticks... and they're freezing my computer.

I'll use it for about ten minutes and the system just freezes for no reason. I have no clue what's going on, so far things are going well. I'm reading that I have to disable Dual Channel RAM to fix this, but the bios doesn't mention anything about it. ARGH! *hits head on desk* What the hell am I doing wrong? (I installed the two new sticks on two slots, and the old RAM is now in the third slot.)

My board's an Abit NF7-S. :\ And yes, it's the latest bios. :(

Check and see that they are full seated in the slots and one just didn't pop up on one side. <img src=smilies/magbiggrin.gif>

Oh I checked, everything's fine. I cleared the CMOS and things seem fine, but I have a question.

I checked the RAM settings with CPU-Z, and it said this about the new RAM:

CAS# Latency: 2.0
RAS# to CAS#: 3
RAS# Precharge: 3
Tras: 7

But, my old memory says this:
CAS# Latency: 2.0
RAS# to CAS#: 2
RAS# Precharge: 2
Tras: 5

Will this be an issue later on?

I have no idea, my motherboard automatically does that for me. Does your motherboard have autodetect for that because it sounds like the motherboard and ram are working at different speeds to me.

I'ld check the motherboard homepage and see if there's any info there or google each item individually and see what results you get on those settings. <img src=smilies/magbiggrin.gif>

as long as your ram was actually manufactured to do 2-3-3-7, then it shouldn't be an issue. double check the packaging/website/whatevz.
that's probably fine, though.

Try running <a href=http://www.memtest86.com/>memtest86</a> and see if any errors pop up. If so, try swapping out modules until you've isolated the defective one.

Notice: It might not be a RAM issue, but a mobo or CPU issue. Hell, maybe even be a PSU issue.

I would except I don't have a new CD burner yet. :p

Anyway, clearing the CMOS seems to have fixed things. ^^

Memtest86 results

No errors.

I left the system running for five or six hours. It ran through the tests seven times, and I got no errors whatsoever, so that's a relief. :)

I did notice that my old RAM was PC2100... but the new RAM is PC2400 (it runs at PC2100 though). Weird. Ah well. :)

I noticed you mentioned in another post, the old ram is slower speed. Try removing the old slow ram and see what happens with the new fast stuff running by itself. Different speed rams == bad news. 9 times out of 10 it's usually the mixing of ram that causes dumb freeze errors like that.

Good luck.
