Q6600 wont boot @ 3.5ghz and bluescreens @ 3.3ghz...

post #1 of 19
Thread Starter 
my Q6600
bluescreens on windows start up @ 3.3ghz,
bluescreens on Prime95 @3.2ghz
and won't even boot up at all @3.5ghz...
however, it seems to be stable @3.15ghz..
CPU idle temp is at 38-41c at this moment.

the mobo is " optimizing " the voltages so currently I havent changed voltage on cpu and ram yet. Should I overdrive this "optimizing" by changing the voltage manually ? if so, how high should I push it up to (on both ram and cpu).

(I posted it once before but I cant find the old thread....)

thank you very much for any of your help !!

You need to manually up the voltages, because the chip isn't getting enough juice.

These are the settings that I use. I have the same setup.(originally posted by Ericeod)

To get 3.4GHz-3.6GHz with your Q6600 assuming the CPU can handle 3.6GHz at 1.5v or less (this OC is very doable with these settings). These arent difinitive, it is all based on the CPU, but these settings are solid for the board itself and should get you started.

Advanced BIOS Features
CPU Enhanced Halt (C1E) Disable
CPU Thermal Monitor 2(TM2) Disable
CPU EIST Function (Note) Disable

MB Intelligent Tweaker(M.I.T.)
CPU Host Clock Control Enabled
x CPU Host Frequency (Mhz) 400
PCI Express Frequency (Mhz) 100
System Memory Multiplier (SPD) 800 (with your FSB at 400, it will 1:1)

System Voltage Control
DDR2 OverVoltage Control: +.03v (default is 1.8v)
PCI-E OverVoltage Control [Normal]
FSB OverVoltage Control +0.2v
(G)MCH OverVoltage Control +0.2v (This is your northbridge voltage, might need +0.3 when running over 400 FSB with quad)
CPU Voltage Control 1.40v - 1.5v (it might need less then 1.40v, or it might need a bit more... only testing will tell)

Depending on what bios you have, you might have to press [CTRL+F1] in the main bios menu to access advanced memory timing options.

I have a question about the Q6600 but I don't want to make a useless thread so I guess I'll ask here. My quad is running at stock with a tuniq tower and my temps under load are 55(core1)/52(core4)/48(core2)/47(core3). To me, the seven degree difference in cores isn't suppose to be happening.

This was happening earlier and I thought it was because I rushed to put the cpu in before I had to go to work. So I came home from work and reseated my hsf and I this time I know I did everything perfectly, so there is no way I messed up applying the tim or seating the hsf on the cpu. The hsf slid around just a little bit while I was trying to line up the holes, but it moved no more than 1/16 of an inch so I wouldn't think that was the problem.

Any help or suggestions would be highly appreciated.
For your health!

It's normal for the Q6600 to have a 5 degree difference between cores. A 7 degree difference is alittle too much. In most cases, the TIM isn't applied evenly or the h/s needs to be lapped.

noob question....will increasing the voltage shorten CPU's life ??

and I followed the steps in your post but it failed to boot up.....think I should lower the FBS a little huh ? (thank you again for the post btw)

Yes, anywhere above 1.5v will quickly kill your CPU.

My question; I cannot get my q6600 stable @ 3.6 (400x9) unless I go around to 1.5v and at that temp its too high! I'm already getting extra cooling to rememdy this problem, what is the best voltage for 3.6Ghz? Thanks in advance

like if I keep it around 1.4v ?

There is no set voltage, since every chip is different. What is your VID? You can find you VID in coretemp. The VID is the stock volts needed for your chip. This will give a rough idea if your chip is going to o/c to 3.6.

Edit: As long as you keep your vcore under 1.5v you will be fine. The safe limit on the Q6600 is 1.5v according to Intel.

I could just be the inbuilt heat sensors or not enough base contact. My TRUE didnt have enough base...

@OP, just do the washer mod and ireckon you will be alright. If that doesnt work then you may need to lap but try washer 1st!
