ASUS M4A79XTD EVO + Phenom II 555 X3 - need advice on stabilizing overclock

post #1 of 8
Thread Starter 
Here is my current system setup:
ASUS M4A79XTD EVO
Phenom II x2 555
A-data Gaming DDR3 1600
MSI GTX TwnFrzR II 560ti OC
XFX 650W PSU
Noctua NH-U12P CPU Cooler 120mm w/ GT AP-29


BIOS Version 2102 6/17/2010

Cool'n'Quiet: Disabled
C1E: Disabled
3rd core is unlocked

FSB: 200
Multiplier: 20
Core Speed: 4000MHz

NB speed: 2600MHz
HT Link: 2000MHz

CPU Voltage: 1.55V
CPU VDDA: 1.28V
CPU-NB: 1.25V
NB Volts: 1.25V

Ram Freq: 1333MHz
Timings 9-9-9-24-33-1T
DRAM Volts: 1.66V

(I didn't set it as 1600MHz b/c I remember my old Phenom 955 had trouble with anything above 1333MHz)

I don't think it's fully stable at 4GHz b/c I woke up with a BSOD after running prime95. Temperatures are very low. Any advice on how I can get my setup stable? I thought I would get higher overclocks b/c temperatures don't even reach 50C!

Ambient Temperature is: 31C
CPU Idle temperature is: 39C
CPU Load temperature is 46C

Core temps should be ~10C lower. I'm not able to see it b/c of my unlocking.

Looks like a solid overclock. BSODs usually relate to voltage on CPU or RAM - either not enough (CPU/RAM) or too much (RAM). Are you sure your RAM is rated for 1.66v at 1333Mhz? I've also found that using FSB and Multiplier like 250x16 helped with stability, rather than just the multiplier like 200x20. You also might try a slight bump in voltage to CPU-NB and NB.

Are you saying I'm putting too many volts for my ram? I think my RAM is rated for 1.65 at 1600MHz. I didn't think too many volts would hurt my OC.

I bumped the CPU-NB and NB...I think I might have to change the FSB and Multiplier combination.

It was a question, not a statement, and yes too much voltage can hurt.

What's the exact model of your RAM?

I ran this test awhile ago and everything was perfect.

I was going to run the test again but I cannot find a USB drive! I had so many of em and now I cant even find one. I don't have an optical drive installed either.

Going to update when I find a free USB I can use...

Alright...so there were 0 errors for the memory at 1333MHz 1.66V when my processor is overclocked at 3.8GHz. Should I do it again when it's at 4GHz?
