What RAM do you have?

I'm using the RAM in my sig. The 1066MHz G.Skills

Some of your settings are off. To get a higher TREF, you'll have to revert to bios 0308. 0219 also has a higher TREF. Under hardware, what voltages is your bios reporting?

So I should downgrade the BIOS to 0308 for the tREF. No problem.

Here's the voltages as reported by BIOS in the Hardware Monitor section:

CPU Voltage = 1.392V
CPU PLL Voltage = 1.568V
FSB Termination Voltage = 1.504V
DRAM Voltage = 2.144V
North Bridge Voltage = 1.648V
South Bridge Voltage = 1.136V
SB 1.5V Voltage = 1.648V
DRAM Controller Voltage REF = 1.072V
3.3V Voltage = 3.296V
5V Voltage = 5.040V
12V Voltage = 12.208V


I'll get back with any changes after I downgrade my BIOS.

THANK YOU for all of your help!! I can't wait until I have this thing stable and can stop bothering you guys.

EDIT: Updated Voltages to what I have set up now.

EDIT (2): So far, with 0308 BIOS, the updated voltages and mem timings fixed as instructed by Zucker2K, I've gone the longest on Prime95 so far. I've gone 20 minutes with no errors. I'm going to let it run overnight and hopefully I can sleep through the anxiety of wanting to check how it's doing every 20-30 minutes

I'll report how it does in the morning.

EDIT (3): Well, it BSODed about an hour into the Prime95 run. I can't complain about that, it's MUCH better than anything I've run before. I'm going to try bumping that Vtt up to the full 1.520 you suggested, Zucker2K. Hopefully that will be what I need.

EDIT (4): With Vtt at 1.520V, I BSODed in about 10-15 minutes. Not sure where I can tweak this to get that full stability.
