Prepare to join the ranks of happy OC'ers!!

That is really weird, but it is an alpha/beta BIOS, after all.

Oh, and I pulled out 4GB or RAM, too.

Right now I´m running Q6600 (VID 1,3125) 450 3600 4x1 1200 555 15 tRD7 with the following setup.

Load Line Calibration: Enabled
CPU Vcore: 1.4875v
CPU Termination: 1.40v
CPU PLL: 1.57v
DRAM Voltage: 2,30v
CPU Reference: 0,800 in ET6 (66,7%)
MCH Core: 1.52v
MCH Reference: (0,760 in ET6) 63,5%
ICH I/O: 1.50v
ICH Core: 1.10v

The ref volt is the most stable for me, can be different with your board and CPU but not by much.

Running HCI for the moment.

With 2x1 I´m stable (LinX 50 loop and 5hrs Prime blend) with CPU Term 1,38, CPU ref 0,760v (63,5%) and MCH core 1,34. Shall retest with higher CPU ref and see if I can lower some other volt.

Hope it can help some

My goal is 500 FSB multi 8 but with the settings above i could even post the computer. It beep many times then restart with a lower multi and when a get inside the bios it show me the red pop up alert about he overclocking and the voltages changes.

Any suggestions?

**Robilar** · 01-04-09

Bios 6 is buggy as heck. Roll back to 5 or the F7a beta.

Enyalius · 01-04-09

I must agree. The F7a BIOS seems to be significantly more stable.

Enyalius · 01-04-09

Well, it seems that I have hit a bit of a wall with my particular chip. I am able to get it solid at 3.4GHz with really low voltages (CPU-Z reads 1.312v with LLC enabled) and only a modest bump in the MCH (1.28, I beleive). All other settings are on auto and it seems to be working like a dream. If anyone else has any settings or suggestions that they would like to share, please do so, but I think i'm going to be stuck at 3.4GHz.

@GL: Your settings did not work for me at all, but thanks for trying. Actually, I tried your voltage settings with a 3.6GHz overclock, and all I got was a black screen. Oh, well.

If it tries to reboot like that it´s usually some thing with the memory setup.

Try to set "Drive Strength Profile" to auto on both channels and try again.

Set tRFC to ~45.

CPU Vcore: You know best
CPU Termination: 1.30-1,35v
CPU PLL: 1.50-1,57v
DRAM Voltage: You know best
CPU Reference: 0,720 in ET6 (63,5%)
MCH Core: 1.30-1,35v
MCH Reference: 0,720 in ET6 (60%)
ICH I/O: 1.50v
ICH Core: 1.10v

Well, sorry to hear that, trial and error then.

Hi Ghostleader, i did the changes you wrote and i get it! I could post and using windows normaly, but didn`t test the stability.
This is my settings

CPU Vcore: 1.3750 (but i run the intelburntest i got temps above 60 and decided low in ET6 to 1.3500)
CPU Termination: 1.30V
CPU PLL: 1,57v
DRAM Voltage: 2.140
CPU Reference: Auto
MCH Core: 1.32v
MCH Reference: 0.718 (ET6 = 0.68)
ICH I/O: 1.50v
ICH Core: 1.10v

Any suggestions to next step? i mean, what should i do to lower the voltages? and do you really think the 8x500 is better than 9.5x422(at lower voltages)?

thanks!!!

Yomny · 01-04-09

Guys is there any way to get the same effects of raising the vcore, i dont want to go above 1.5 actual windows vcore but i may need a tad bit more voltage to get my current FSB stable? I have vtt and pll at stock settings. Thanks
