4800+ X2 fails in super_pi & Prime95

[LOUISSSSS]

just build my new system and did some stress testing on stock settings
new rig in the signature.
in super-PI i get the error "not exact in round" when trying to calculate 2M
in prine 95 torture test i get a FATAL ERROR after about 5 minutes running Test 1, 4000 lucas-lehmer iterations in M19922945 using 1024k FFT length

i'm running 2 x 512 kingston value ram at 3-3-3-8.

any ways on how to fix this? or what the problem is?

There's a problem with your ram....check to see that your ram timings and voltage is set at the correct values, you could also increase the dimm voltage to attempt to make it stable; then run memtest86. Also, download cpu-z and make sure your motherboard isn't undervolting your cpu and check your fsb values.

Make sure you're giving the cpu >=1.35 v

Yup since you're on a DFI the board may be undervolting the CPU a bit.

Yup, my DFI undervolts by about .25v

it's large FFT and superpi errors...

therefore it's most likely mem error...

Run something like memtest86 to check for problems with your memory.

thanks guys but my new OCZ PLATINUM 2 x 1gb 2-3-2-5 will be coming from ZZF in about 2 days, might as well adjustt it then, btw when you say adjust, it is in the DFI bios right, as of now i think everything is in auto. can someone with exp with DFI pheonix bios help me adjust my CPU to the correct voltage?

My DFI board undervolts by around .5v.
