Q6600 Problem Core?

[Guest2]

The higher clock speed does make a lot of difference. All i was highlighting is the fact that even a small increasing in mhz can need a lot more voltage.

This. Voltage and tweaking other stuff like memory settings. Have fun with this point "I reckon I could push it up a wee bit to 3.6Ghz easily if required"

3.2ghz - 3.4ghz was a massive increase for me. I needed a new chip to get me past 3.4

I'll give it a go up to 3.4 and see how things are then.

May aswell head straight to 3.6, if it works try for 3.7 I meant it was a massive increase in terms of getting it stable at 3.4, not performance wise. 3 - 3.6 is quite a big step though

Okeydoke. Well I'm reasonably new to all this o/c'ing lark to be honest but I'm learning all the time by reading these forums. Can't think of a better place to be asking advice from folks like yourselves.

What is your vcore setting for 3.2GHz? I have the same motherboard, but I can only get 3.2GHz with 1.450v

Did you do the pencil mod?

I take it you guys are compensating for the FSB increase by upping relevant board voltages too right?

Just thinking cus P45 can do 400 FSB on stock volts.

 

[Draeger]

Haven't done the pencil mod, no. I should really look into that.

Vcore at present is set in BIOS at 1.400v and shows in CPUZ as 1.352v with droop :-

That looks quite good compared to mine. I'm not at my computer now, but I think CPU-Z shows the vcore as 1.2xxv, whereas the vcore in the BIOS is set at 1.450v.

board voltages? I have a P45 board. I have increased things like CPU PLL and MHC Core if thats what you mean. There arnt too many board volages to alter really, most of the different voltage settings are related to memory (RAM)

 

[Justintime]

Shouldn't really need to touch the other voltages on a P45 for 400FSB, only RAM and cpu mainly.

When you guys talk about your CPU does X.XGHz at x.xVolts are you tlaking about real votages displayed by CPUz or what you are setting in the BIOS?

e.g I have set Bios to 1.4v but in reality its 1.3v to run 400x9.

 

[alexp999]

on my deluxe, with LLC enabled, whatever I set is what got applied, even under load.

Wish my C4F was like that, overvolts by about 0.035v under load

I always talk about volts relating to BIOS. However my P45 has terrible Vdroop. 1.56v bios is something like 1.34 in cpu-z when loaded. I'll have a look in bios and what it is in cpu-z load tonight and report back.

Probably best we go on CPU-Z load volts to aviod confusion.

I always refer to the voltages set in the BIOS, unless otherwise stated.
