im really stuck so far every time i run the small FFTs test in prime 95 my comp crashes cant seem to make it stable and worried if i up the volts any more i might fry cpu.

my cpu idles around 28-29 C

load upto 50C maybe abit over when running prime95

my stats are
amd 955 black edition C3
Asus M4A89GTD PRO mother board
Ripjaw 4gb 1600mhz ram ddr3 F3-12800CL8D-4GBRM
am using air cooling in push pull config

just used a program called turboV seems to of clocked my core to 3.8ghz stable at 50C running prime 95 atm if i leave it clocked at this speed with temp at 50C full load will it be ok?
 
You may should have done some serious research on the memory you chose to buy, that memory was specifically designed for an Intel motherboard and yours isn't in the list.

That is not to say you won't be able to still use that memory but probably with cas 9 timings like 9-9-9-24, it was rated at cas 8 for the Intel motherboards it was designed to run in.

Also run 1.60v on your DDR3 slot, that's what those modules run at.

And disable the CPU load line calibration, and really any load line calibration, or CPU spread spectrum and any other CPU function like cool and quiet, that will affect your end results.

ok cool thanks i was looking at diff memory but that was recommened by alot of people on the home built section of this forum so presumed it would work. also i have 3dmark06 have ugraded to the full version but every time i run it the cpu tests run at 1fps every other test runs fine it does this even at stock settings any reason for this that you could think of?
