Hi guys. as the self-explanatory title says, my system is unstable due to memory issues.

Let me reproduce the message I've sent to tech support:

Dear GEIL team:

I have recently purchased 2 GB (2 packs of 1GB) from your GeIL Ultra Platinum PC3200 400MHz Dual Channel DDR Kit (http://www.geilusa.com/proddetail.asp?linenumber=18# ), and installed them in my DFI Lanparty NF4 SLI-DR (http://www.dfi.com.tw/Product/xx_pr...jsp?PRODUCT_ID=3449&CATEGORY_TYPE=LP&SITE=US).

I'm getting, due to that, several instabilities. The system works, but reboots occasionaly, after long periods on (long, as in a several hours in a row). Except if I try to run games (I used Doom3 and Half-life 2 with your memory in)... than the system locks or reboots (either as usual or bringing a blue screen with white text, too fast to read), and all the instability shows up in a matter of half an hour at most.

I tried using the only two modules, the problem remains with every combination of my four. I tried using only one module (to see if the problem was with the dual mode), and the instability is still here, though it takes a little longer to occur. Any of the four models, used alone, will cause it.

While evocative of a defect in the memory, I decided to ask you guys if the memory is supposed to be compatible with the moderboard in question (I had little doubt that it is, but than again I have not seen it in your compatibility list), and, if there is, if it happens to have any kind of known issue or special configuration that I am supposed to make in order to solve it (because I find too much a coincidence that ALL FOUR modules are defective).

I should also point out that I am running the system, right now, with generic memory models (and in dual mode), and it is working just fine, including with the very same games installed (and the very same instalation I used when I was getting the reboots, didn't need to reinstall them, just swiched the memory modules).

Any assistance on the matter will be most welcomed.

Your costumer,

Frederico Chagas.

I'm still waiting the reply, but I figured I should post it here as well, and see if anyone has had (and solved, hopefuly) a similar issue with the same parts.

Regards :).

Umm isn't GEiL memory for apples?

Nevermind, only GeIL chips I had seen before were the apple series at newegg.com . I would check the voltage in BIOS as the page says it requires between 2.55V and 2.95V which I believe is a little higher than standard.
 
Well, it required a little more than that, but you were in the right track.

What happened was that the version of the chipset BIOS had a bug which reset the memory back to 2.6 volts even if I set it to the specified voltage. A simple BIOS update has apparently solved everything, now. I'll have to test a bit more throughtfully to be completely sure, but I just have had a 2 hours Doom3 session, and a 40 minutes HL2 session, both without any difficulties whatsoever, to hint me in that direction.

Anyway, thanks for the tip.

Regards :).
