you didn't change it, you left the MCH @ 1.1v and IC also @ 1.1v? So what could i be doing wrong? I disabled all the right things maybe in need to up that MCH skew setting? Do you think you can post some of your bios settings or maybe a screen shot of your ET6? Thanks for any input you could share.

My mch is @ 1.3 and ICH is @ 1.1. Comparing my settings to yours isnt going to help since you have a 65nm Quad and I have a 45nm Quad so the voltages are gonna be different. Your Q6600 may not be a great Overclocker or your hitting a FSB hole.

I have just start to play around with my Q6600 and so far I´m at 450 3600 1200 555 15 tRD7 Turbo.

I notice that when I went from 1:1 to 3:4, I couldn´t boot with MCH core higher then 1,28, with 1:1 i could boot up to 1,40, it runs okey at 3.4 with MCH core between 1,22 and 1,26, so be careful with MCH volt and try lower value.

I also need at least 1,34 CPU Term and CPU PLL 1,57 otherwise it couldn´t boot when it´s cold, when it´s warm I can boot fine with 1,30 and 1,50.


This P45 chispet is a bit senitive if I compare to P35, X38 and X48.


Right now I running 450 3600 1200 555 15 tRD7 Turbo with this setup

Load-Line Calibration........:Enabled
CPU Vcore.........................:1.48750
CPU Termination...............:1.34
CPU PLL............................:1.570
CPU Reference..................:63,5% (0,76 in ET6)

MCH Core..........................:1.220
MCH Reference..................:63,5% (0,76 in ET6)
MCH/DRAM Reference........:Auto
ICH I/O.............................:1,500
ICH Core...........................:1,100
DRAM Voltage....................:2,300
DRAM Termination..............:Auto
Channel A Address Vref......:Auto
Channel B Address Vref......:Auto

I hope this can help you.

What RAM config do you run?

Thanks a lot for your help. When you test your FSB do you set your multiplier to 6? I usually do that and only mess with the MCH core, the reference is set like yours at .76 all else is manually set to stock values. Well right now i m running 356 at stock 1.1 MCH so i really think i could go higher, maybe it was something i did earlier. Thanks again for your support.

Setting the multi to 6 is a good start when test for high FSB, I do the same.

In my case I needed CPU PLL 1,50, CPU Term 1,30 and MCH core 1,20 to reach FSB 400.

For FSB 450 I needed CPU PLL 1,57, CPU Term 1,34 and MCH core 1,22.


Make sure that your RAM don´t hold you back when you go FSB 400+.

Set Latch 400 Multi 2,00D Static tRead Value to auto (0) in both channel.

anyone else finding a hard time to get drivers for this board....I spent a good 30 minutes hunting down the GSATA raid drivers....sheesh

@Ghostleader, so even though the cpu is underclocked(sometimes) when setting the multi to 6 you still need to raise the pll and term voltages? i didn't know that, i thought you only raised that in order to fine tune the vcore.. Thanks alot. +rep for you

Nope, the Windows drivers were all on the nice DVD that came with it. I really hate open box.

Well here we go.

With higher FSB you need higher PLL to be able to boot into Windows.

With higher FSB you need higher VTT (CPU Term) to be able to run that higher FSB stable in Windows.

But there´s a combination between those also, proper PLL and to low VTT don´t always work and the other way around.

And then you have CPU ref, MCH ref and MCH core to consider also.


I´m not 100% sure so someone with more knowlegde in this area have to put it right if I´m wrong.

thanks that should be more than enough for me to start messing around with.. About after how much of a pll and term increase should i know i need to increase the MCH core and leave the PLL and Term alone? In other words how much PLL and Term increase is enough or safe? Thanks
