Q6600/Abit IP35Pro questions again.


May 31, 2009
I had to make my own topic to finally find answers cuz my knowledgement about oc'ing is way too low and even my skills of english make it hard to understand to get the big pic from all the topics i have read. 4 weeks behind of hitting my head to wall so i begin to be pretty frustrated.

Anyways... Im trying to reach atleast 400x9 or any fsb x X to try to find max stable speed. I have stucked on 3333MHz

Here's my issue:

I cant go over 370x9 or 400x8 or dont kno how to go over them. I have tried core v from stock up to 1.490: fsb 370, 380... 400 (x9) (also 400+ x8). Every single combination of voltages gives a bluescreen or hanged on Windowns loading screen. 370x9 works fine, but even +1 (371x9) gives bluescreen. 400x8 works fine but again even +1 gives a bluescreen. I have set also higher ICH, ICHIO etc. (I have set voltages by small steps as quided)

Some1 told me about cpu vtt to set it higher when using higher fsb. For example 1.3V. But I dont see higher values than 1.20 and 1.23 on the list in bios. So how to set higher cpu vtt?

A questions abou dram divider:
I have read some threads about that but i didnt find the answer: what divider i have to use? Is there max value i should not exeed? Why different programs show different divider?

- bios 1:1
- Everest Ultimate 12:8
- CPU-Z: 2:3
(- bios default: (ddr2-1110): 1110 too high or anyway bad choice?) (Corsair Dominator CM2X1024-8500C5D DDR2 SDRAM 5-5-5-18 @ 400 MHz)

If some1 could write 'oc'ing for nub' instructions i would be more than happy.

Here's last settings, they work fine.

FSB 370
Core v 1.3850 Everest Ultimate: 1.37
Cpu vtt 1.20
DDR2 2.1
DDR2 speed:
(atm default in bios: (ddr2-1110)
Everest shows this:
- Memory Bus 555.0 MHz DRAM:FSB Ratio 12:8
- CPU-Z: see the pic below
MCH 1.25
ICH 1.05
ICHIO 1.50

You're pushing the ram way too hard. You need to back the divider down to lower the speed or relax the timings. Get the CPU stable first and then push the RAM. I have the same CPU, MOBO, and similar RAM.

I set divider to 1:1 (776) CPU-Z shows: DRAM Frequency: 380. This is good?

I dunno what i did different at this time than earlier when i got bluescreen after bluescreen. I started again from stock to set things higher. First FSB. Now i reached 380x9 = 3420MHz

Here's the voltages and temperatures from bios:

Temperatures (load)
Motherboard 26 °C (79 °F)
CPU 36 °C (97 °F)
CPU #1 / Core #1 45 °C (113 °F)
CPU #1 / Core #2 31 °C (88 °F)
CPU #1 / Core #3 37 °C (99 °F)
CPU #1 / Core #4 35 °C (95 °F)
PWM1 39 °C (102 °F)

Voltage Values
CPU Core 1.38 V (in bios 1.4250)
DDR2 2.100
CPU VTT 1.23 V
MCH 1.29 V
ICH 1.09 V
ICHIO 1.50 V

Setting anything lower or higher gives a bluescreen. So this is best i can get?

EDIT: When i pressed "Submit" to post this message I got bluescreen, so everything isnt ok yet.
