AMD HD Radeon 6870 Crossfire causes BSOD and Freezing in games

Hey everyone. I just recently bought another card to xfire for my rig. Since ive done this however my games randomly freeze or bsod, or freeze with a loud buzz until i shut my rig down.. i think its a driver issue, because it used to do it when i had 1 card and i bumped it down to like 11.10 and everything worked fine.. but when i got the new card, apparently 11.10 didnt support xfire.. so i had to update to 11.12.. and now i have my issue..

When having stability problems the first thing you want to do is not OC, don't start OC until you have the system running stabile.
Check you ram timings in BIOs and make sure they are correct.
Try bumping up you ram voltage and see if that helps.
Try upping your graphic card voltage a little.

Here is a screenie of my GPUZ



and here is a image of my CPUZ report... If someone can look at that for me and maybe tell me if my voltages are off for what i got it set as, i always get confused as to what they should be..

OK, so put my Processor back to 3.2ghz stock. and checked my memory, its at 1.5v recommended for 1600. and i tried running benchmark on arkham city. it ran fine, ive had physx enabled even though i dont have ATI cards, the benchmark finished with about 25fps ave with physx on and max of 55. but then when i went to exit the benchmark, game froze and a very loud noise persisted until i had to hard reset the comp....

i think that vcore voltage of 1.519 is set too high causing your system to overheat well playing games.
what do your temps look like ?

just found this on newegg maybe it will you.

Manufacturer Response:
Dear Valued Customer,

Sorry to hear about the issues. 16GB and 32GB functionality is very much processor dependant (Deneb CPUs have limitiations when it comes to memory frequency with high density modules).

In any case, relaxing some of the memory timings and increasing CPU/NB voltage can help stabilize the system:

1) Set DRAM Read to Read to 7

2) Set Command Rate to 2T (AKA Command Mode)

3) Set CPU/NB voltage to around 1.30V

4) Set DRAM VOltage (VDIMM) to the specified voltage of the memory used.

Regards
ASUS Customer Support

i will play a game soon and then screenie coretemp and post it. Lets close that door first, then i can try the voltage and timings on the memory etc. stay tuned!

Can you post a pic of your memory settings with CPU-Z.

here's a pic of the memory.. my Mother board initially had it set to 1300 but its 1600 stock, i read that some boards like mine for some reason always set it to 1300, so i manually changed it to 1600, but checked on my packaging for the memory that its supposed to be 1600 for sure.
