Hi All,

I recently installed new RAM in my two year old PC and I am now throwing a BSOD WHEA Uncorrectable error sporadically. I have tried updating all drivers, stressing the ram with memtest86+ for >10h ours (zero errors), ran sfc /scannow, turned off c-step in bios, reset cmos, ran chkdsk, ran HDD stress test, and ran RAM with XMP profile and with standard (no change in BSOD). In addition my power supply seems stable with the following readouts:

Powersupply
Vcore = 1.268V
DDR15V = 1.504V
3.3V = 3.376V
5V =5.053V
+12V=12.175V

I have tried reading the dump file but i cant make heads or tales of it. Any help would be greatly appreciated!

bugcheck 124 is called from the CPU most often a incorrect voltage and clock frequency applied to the CPU.
most often it is a incorrect volatage applied to the CPU memory controller that results in a CPU cache error.

so: update BIOS if you have a update or check the BIOS CPU voltage values are set correctly.
if I remember correctly it was VCCPLL setting being too high or too low. (for the i7 920 cpu)
some BIOS will set the value too high. (I think it should be 1.80v)

Thanks for the tips. I have the latest bios installed. I am not sure how to adjust the voltages that you have pointed out. An interesting thing is that if i take out the new ram and put the old ram back in, the error stops. At first I thought the memory was defective so I had a replacement sent to me but the same error started happening once I installed it.

Any other ideas would be greatly appreciated.
