I had issues with a gigabyte ep45-ds3r and a perfectly fine graphics card once, bios update fixed it, might be worth a try if you haven't already. Another thing you may want to try is upping the voltage slightly to your GPU and seeing if it keeps doing it if you can.
Wrong. The above mentioned configurations of 2x1GB + 2x512MB for dual-channel worked absolutely fine with some AMD x2 mobo I've had. Last one it worked on for me was a DFI lan party nf4 running Athlon XP cpu. I would consider this setup from a "few" years back.
Not sure what you think I said contradicts what you're saying but I've used a 2x1gb + 2x512mb with a p965 chipset board with no problem too. Matching pairs in same color slots was never an issue with dual channel. What was an issue with Intel boards of a few years ago (p4 boards, 865, 845 chipsets and others) was that dual channel was very finnicky. If different timings, capacities used in same color slots, dual channel will not work. I recall that well since I had difficulty finding a a 256mb module that would work in dual channel well with an older 256mb one I had. AMD may be an entirely different beast so cant really comment there.
Does anyone know what the problem could be? It's still locking up my computer. Temperatures are still fine and so are the drivers and Windows etc. :/
I've checked everything. PSU, CPU, everything. Ram sticks are fitted perfectly and ran benchmarks on them as well as the CPU and everything but running a benchmark on my graphics, it hangs. :bang:
try older driver 270.61 or 270.90tesla. ..... you can have 1+2gb and have Dual channel on "newer" mobo's, this is called Flex Mode. I got this from my mobo manual. So yea in his case its working in Flex mode:nerd:
I was aware that newer mobos were more flexible with dual channel configs, but didnt know it was called flexmode. Anyway Intel has a thorough explanation of dual/single channel and whats possible or not with with various dimm combinations: http://www.intel.com/support/motherboards/desktop/sb/cs-011965.htm
Same as Northo, the drivers didn't work for me. Don't think this can be solved. Might have to return this card for the GTX 560 I guess. :/
Yeah, I'm planning to return it. Thanks anyways guys, was really worth the time to try and see if the issue could be fixed.
If you really think it is the GPU use MSI Afturburner to bump the voltage a notch up from default and see if that fixes it. Unstable Video Cards don't hang the entire system up usually though. Did you test the memory with Memtest by chance?
Tested CPU with Prime95, Mem with Memtest. Everything. But running benchmarks on the gpu or playing games on it leaves it hanging.
