Help getting 3.6ghz on q6600 and p5q

I've been able to overclock it to 3.4ghz with the following bios configs:

FSB: 425
MULTI: 8
DDR's: 1066Mhz
Vcore: 1.4000
CPU GTL: AUTO
CPU PLL: 0.58
FSB TERMINATION: 1.40
DRAM VOLTAGE: AUTO
NB VOLTAGE: 1.36
SB VOLTAGE: 1.20
PCI SATA: 1.50

Which values to do 3.6ghz??

FSB: 400?
MULTI: 9?
DDR's: 1066Mhz
Vcore: 1.4750 ?? more?
CPU GTL: AUTO
CPU PLL: ??
FSB TERMINATION: ??
DRAM VOLTAGE: AUTO
NB VOLTAGE: ??
SB VOLTAGE: 1.20 ??
PCI SATA: 1.50

The cpu as a vid of 1.325

I appreciate any help you experts can give me..

Thanks.

Ive seen cpus with the same vid and on air hitting 3.6....

Heat is not a problem if you have even a half decent air cooler. I get 57-60C(variable among cores) at 3.6ghz and 66-69C at 4ghz.

For 3.6ghz on high vid g0 q6600, use 1.45-1.5 vcore, 1600mhz fsb, 9x multiplier. P45 runs at 1600mhz fsb natively, don't increase chipset voltage. Turn on loadline calibration if it's supported by the board.

Stop being so pessimistic. My Q6600 easily does 3.6 (stable) on air.

My settings are something like this (VID = 1.3000V):
FSB: 400mhz
Multi: 9x
CPU voltage: 1.48125V
FSB: DRAM : 1:1 (DDR2 800)
RAM Voltage: 2.1V
RAM timings: 4-4-4-12

I left everything else on automatic.
You will probably need more voltage than me because your VID is slightly higher. I recommend 1.5V.

If your objective is to see how high you can overclock, and the accompanying bragging rights, then go to it. Your results will be determined by your skill, bank account, and how lucky you were in buying an exceptional chip. They do vary.

If your objective is better gaming performance, then anything over 3.0 or so won't make much difference in almost all games. The vga card is much more important.

If you have an application that is cpu bound, and uses all 4 cores, then overclocking can be good.

Otherwise, don't bother much.

Quad vs dual in gaming.

I like that link.

You have to keep in mind, none of them test overclocking. The Legionshardware one overclocked some chips, but not q6600 for comparison. Guru3d just tested stock 2.4ghz q6600 against 3.0ghz e8400, and end up with a few fps gain in some games, none in others. Only the xbitlab one I linked earlier tested both dual and quad core clocked at similar rates, which illustrates how duals/quads behave.

Run cpuz during stressing and see how much of a vdroop you get. Also keep eye on temperature.

Also, decrease ram to 800 at 1:1 ratio to rule it out as possible cause of instability.

Ummm, that is strange. That looks more like vUP, lol. It could be that CPU-Z isn't reading properly or that you don't have any droop. vdroop means that your vcore decreases during load.

For example, my mobo has pretty bad vdroop and during SuperPi 1M will drop from 1.56v to 1.51v.

My PQ5 Deluxe does the same thing. Instead of going down the vcore is raised during a load. I do have Loadline Calibration on. The max FSB on the PQ5 seems to be about 490.

As for your problem, looks like your ram is a bit high on 5-5-5-15 for PC6400:

RAM : 4096 MB DDR2 Dual Channel
RAM Speed : 531.3 MHz (4:5) @ 5-5-5-15
Slot 1 : 2048MB (PC2-6400)
Slot 1 Manufacturer : Team Group Inc.
Slot 2 : 2048MB (PC2-6400)
Slot 2 Manufacturer : Team Group Inc.

You might have to set your timings manually or lower your ram speed (it will probably be your ram speed that you need to slowdown). On my "auto" setting the BIOS will set it at 5-5-5-18 no matter what. It doesn't compensate for the higher FSB. The is odd, because my other boards will relax them when going higher.

My B3 Q6600 will not stay stable at 3.6 on this board or any board. I can manage 3.33 which is in a good safety range. As for my Q9450, I was able to squeeze another 240 mhz by using the deluxe version of the PQ5.

Okay, the info was taken from your CPU-Z screenshot.
