P5q deluxe problem?

[issepower]

So today I started to play Far Cry 3. Everytime after 5-10 minutes te game crashes and i hear the GPU (asus gtx570) restarting(fan spinning fast and then slower).

My Q8300 was overclocked so i thought it was maybe a bad overclock. I restarted my pc with cpu stock speeds and then windows alway got stuck at logo and crashed. My ram are 2x2gb G Skill F2-8500CL5D-4GBPK.

I started to search what the actual problem was so I removed one of the DIMMs. Then Windows did boot. 2 Dimms are working but separatly.

Now should I RMA the motherboard or is the problem somewhere else?

Any help is appreciated!

EDIT: I also resetted the CMOS, but nothing...

I would run memtest86+ before sending the board in. You don't typically expect freezes with bad RAM, but then bad RAM can run a pretty wide gamut of symptoms.

But the 2 dimms separately are working perfectly..

Memtest86 only works with 1 dimm( tested every slot). Tested two dimms

So motherboard not working properly then?

Did you try running the ram at DDR2 800 instead of 1066?

 

[issepower]

I run it 1:1 so at stock speeds its 667

nobody?

Have you tried putting the memory in slots 2 & 4 ? That is if you're currently using 1 & 3.

If running the RAM in dual channel freezes the system and single channel does not freeze the system, I would suspect the memory controller in the motherboard being faulty.

I think bumping up the nb voltage from 1.4 to 1.5 did the trick. Just because that 0.1v

Weird no? My board is now definitely unstable right?
