Q6600 G0 + Rampage Formula Overclocking

[Sticklyman]

Hi,

I have the Asus Rampage Formula with a Q6600 (G0 stepping). I have managed to overclock to 3.4GHz but I am unable to keep the system stable at any higher overclock.

My system:

• Asus Rampage Formula
• Q6600 G0
• OCZ Gold 2x2GB DDR2 - OCZ2G10662G
• Titan Fenrir
• Windows 7 Professional x64

I have stress tested my PC with both Linx and Prime95. It appears that Linx is a much more strenuous stress test as it produces core temperatures that are about 7 degrees higher than Prime95. I have run 20+ passes of Linx and 8+ hours of Prime95 & my system has remained stable.

I would like to try and push for 3.6GHz if I can, but I am unsure if my hardware (specifically my CPU) can cope. I have measured my temperatures using Core Temp. There is always a large temperature gap between the two pais of cores, with cores 0 & 1 being higher than 2 & 3. I believe this is faily common with this particular chip. Please correct me if I am wrong. Also, which temperature should I trust (if any)?

CPU-Z:

My Temperatures:

Idle:

After 30 minutes of Prime95:

After a few passes of Linx:

My voltages are:

CPU Voltage: 1.46875V (in BIOS)
CPU PLL Voltage: 1.50V (in BIOS)
FSB Termination Voltage: 1.20V (in BIOS)
DRAM Voltage: 2.02V in BIOS but the BIOS hardware monitor measures that as 2.08V
Northbridge: 1.25V (in BIOS)
Southbridge: 1.00V (in BIOS)
Southbridge 1.5V: 1.50V (in BIOS)
DRAM Vref: 1.040V (in BIOS)

I have been unable to get the CPU stable at less than that voltage. Could anyone give me some advice as to how I can try and improve my overclock?

Thanks a lot!

To be honest the rampage formula is't that good for overclocking quad's it's better for dual's. You might want to look at the asus forum site to see which bios is better for the q6600...

p.s you might want to up the n/b volts but keep a eye on temps.

best of luck.
