***The Official Q6600 Overclocking Thread ***

D'oh... I didn't see that post either about no more money to be spent d'oh.

Was just thinking about my overclock with my Cooler Master 212 with two fans at 1800RPM that even at 3.4Ghz and 1.35V (1.3V at load), the temps seem rather high

Prime 95
Core 0: 73C
Core 1: 73C
Core 2: 69C
Core 3: 69C

Prime 95 and furmark
Core 0: 77C
Core 1: 77C
Core 2: 73C
Core 3: 72C

Just thought they would be lower, given the low-ish voltage. Really going to have to take a look at my air flow in the case (move the 5850 down to the lowest x16 slot), and replace the Akasa Amber 12CM 1300 RPM fan with something better!! Was also thinking that maybe I could put a 14CM fan on the side of my case to help airflow over the GPU's.
 
Yeah, I didn't use enough the first time I did mine and was getting 30-40 idle, reapplied using a pea sized blob in the middle of the chip and dropped down to where I am now.

Might be worth a go.

thats helped quite a bit thanks :) ill just ease the Bus clock up 20 a time then and see how much i can do it before changing the voltages/multiplier

That’s definitely how you should go about it buddy, but you may find that your board won’t play ball at certain qdr frequencies. Asus 650i boards have ridiculous memory holes! DDR 830mhz might not work but an extra 20mhz might run perfectly. bios updates might have helped with this though.

Assuming the 650i P5N-D is very similar to the P5N-E bios wise this is how I would go about overclocking yous.

how I setup my P5N-e.....

"To manually setup your ram get into your bios and go to 'Memory Timing Setting' in the advanced section, you may have to change AI tuning to manual to allow you to change ram latencies.

You want to manually set these values for your ram to the correct timings, leaving it on auto is a no no! Command Per Clock (CMD) should be set at 2t regardless.
You are ok to leave advanced memory setting all on auto though.

Go to your 'Voltage Control' tab in the bios and set 'Memory voltage' to the correct voltage specified by your ram manufacture.

Finally go to "FSB & Memory Config" and set to unlinked and set 'MEM (DDR), MHz' the correct ram frequency. Unlinking you ram will lock it at its stock frequency thus factoring it out when overclocking.

now you should be able to gradually up 'FSB (QDR) MHz' from stock 1066”

I hope this helps ya, but as I said these boards are a pain in the but and at times you can get stuck at a pathetic 200mhz overclock if not setup correctly.

Even with a perfect setup your 3.2ghz is a little optimistic, I wish ya good look getting close though :)

Give us a shout if you get stuck

Last night I spent a few hour's taking the machine apart and applying new paste to the cooler (pea sized blob i the middle technique this time), trying to figure out how to take off the northbridge cooler to apply more paste (didn't manage it), and sorting out general airflow.

The northbridge cooler screws were not particulary tight so, after trying to remove the cooler (i didn't have a pair of small pliers for Asus's push pin's d'oh) I settled for tightening the screws up instead (They are on springs). Even though I also removed the small 50mm fan from the northbridge, temps seem to have improved, and it was at about 52C with prime 95 running compared to it's previous 60C. Might be ambient temperature difference but it didn't feel cold in the small room. It also is not shooting up so quickly, so hopefully a positive affect :-) Given the positive affect on the Northbridge I may put a small fan on there again to get temps under 50 :-)

The CPU temps seem to be the same or a little worse :-( I'm using some Artic Silver 3 I got donated so possibility of getting some better stuff, but I doubt it will make things 'that' much better. The CPU was tightened down more than before as well.

I moved an HDD to the bottom of the case to allow air to flow up past the 5850, but I haven't moved the 5850 for the moment, so potentially room for improvement.

I still think that getting a better rear fan is going to help as with 2x 120mm's push/pull through the HSF I expect air isn't getting out of the case quickly enough with the slow moving fan on the rear. Will probably get a 2nd akasa apache to match the front fan :-)

Ive got my new 750W power supply because i got a new GTX 480, so want to attempt overclocking my Q6600.

Dont want to go overboard, 2.8-3.0 Ghz would be good enough for me.

Was just doing a Benchmark using Resident Evil 5 and task manager was showing CPU going crazy!

I have a PN5-E-SLI board and a Freezer 7 cooler.

Current temps are 44C on the standard settings.

How do i get started? What are 'safe' settings to get me started with and then checking the temps.
 
There is no "safe" setting, all systems respond differently to overclocking and it doesnt help that the p5n-e is a fickle board.

Check out my above post, I explain how to configure the p5n-e board and start overclocking it.

Any overclock will help reduce the bottleneck caused by your stock clocking quad when paired up with a gtx480, so it’s worth a punt.

Is the correct RAM voltage and frequency listed on the RAM modules?

Is the 'FSB (QDR) MHz' the overclocking? How much should i increase each time before i reboot?
Do i need to apply fresh thermal paste on my cooler to CPU before i even begin? What temps are to high?
 
Can I get an okay OC with a G31 chipset? I feel tempted to get it to perhaps 3GHz, I've gotten up to 3.6 before, if I remember correctly, and higher got a BSOD when testing, can't remember voltages.

3GHz without major voltage increase on a G0 Q6600, on a GA-G31M-S2L, Tuniq Tower 120 for cooling. Can do?
 
i need some advice.
i have my q6600b3 at 3.3ghz, 413 x 8.
my ram is at 5-5-5-18 CR is 1T @495 mhz 5:6
ignore the geekbench score, its for somewhere else ;)

is it worth me trying to tighten the ram timings? the default is 5-5-5-18, but could i run it at 4-4-4-12?

is the CR of 1T affecting the overclock?

also this is stable (20 runs of ibt with custom ram) but max temp is 70.c so i know i cant go higher, with my present cooler (tuniq tower 120)

but if i put the divider at x 9 i can only get 3.0Ghz stable (333 x 9) and cant get any higher :confused:

yes, my old mobo was a g31 chipset, and i got it to 2.9ghz on it, with my b3 q6600
 
1t cr at near as damn it ddr1000? certainly doesn’t seem to be affecting your oc!
I would be surprised if you could tighten the timing.

I would have thought you would be able to run 366 x 9, why you are hitting a wall at 3ghz on that 9 multi is a bit of a mystery to me. could be an nb strap issue maybe.

I wouldn't worry about those temps tbh, you'll probably never see them go that high unless you're stress testing again. They are quite typical for 65nm quads.
