[Old School] Help Overclocking a Q6600 Please!

post #1 of 4
Thread Starter 
Hi,

Ive formed a computer out of an unusual mixture of old and new spare parts (specs below)... I have a GTX 760 installed but I dont think its living up to its full potential due to the old Q6600 processor. So I was thinking of overclocking it from its stock 2.4GHz up to around 3.0GHz which will bring it up to more of the requirements for modern games and hopefully wont be such a bottleneck.

The problem is Ive never tried overclocking before! Ive always bought pre-overclocked motherboard bundles for ease. So I was wondering if people could give me some advice please?

Theres actually a massive 41 page thread on this forum discussing overclocking this exact motherboard and CPU: www.overclock.net/t/300149/3ghz-q6600-oc-on-p5n-e-sli/ but it dates back to 2008 and the BIOS version has been updated since and are using much different hardware and OS (if that matters). Since Im new to this, some exact numbers to try would be best please and ideally where I could find them in the BIOS menus.

Secondly what would be a good cooler to buy to replace the stock one so I can overclock it?

Many Thanks! thumb.gif

This should give you the basics for such a minimal OC on that chip. For such a mild OC, on the C2Q, just raise the FSB, up your vcore, and set the divider. That was when overclocking took 10 minutes to do.

As far as a cooler, depends on budget and how much you MIGHT decide on overclocking in the future and what your case allows.

Before i left my LGA775 platform behind, i had a Q6600 @ 2.8Ghz with a GTX 560 Ti and the CPU was still a massive bottleneck, though the small overclock did help a little.
As soon as i changed over to a 2500k, the framerates jumped up. I reckon you need a more powerful CPU if you want to get more out of that GTX760 thumb.gif

Thanks for the help. Since my last post I have bought and installed a 'Zalman CNPS8900 Quiet Heatsink and Fan' which seems to work really well at keeping the temperatures down. I had a look at the thread you posted and applied the suggested settings (however am confused by the values in the 'FSB' row as they seems really low?).

I successfully overclocked it to 3.04GHz and ran Prime95 for nearly 2 hours and everything seemed fine with the temperatures never going above about 65 degrees. However, since overclocking unfortunately my system is blue screening a lot (various different errors) even when just idling. Please could you have a look at my settings below and see if you could see something to alter to make it more stable:


VOLTAGE CONTROL:
VCore Voltage [1.43750V]
Memory Voltage [2.353V]
NB Core Voltage [1.393V]
VCore offset Voltage [Auto]


FSB & MEMORY CONFIG:
FSB - Memory Clock Mode [Unlinked]
FSB - Meory Ratio Auto
FSB (QDR), MHz [1300]
Actual FSB (QDR), MHz 1300.0
MEM (DDR), MHz [800]
Actual MEM (DDR), MHz 800.0


CPU CONFIGURATION:
CPU Internal Thermal Control [Disabled]
Limit CPUID MaxVal [Disabled]
Enhanced C1 (C1E) [Disabled]
Execute Disable Bit [Disabled]
Virtualization Technology [Disabled]
CPU Multiplier [9.0]
Enhanced Intel SpeedStep(tm) Tech [Disabled]



One thing to mention is in the past my computer was blue screening a lot (stock settings) so had to manually set the Memory Voltage to 2.353V which fixed it. Maybe now the other voltages are higher the memory isnt getting enough voltage again and is crashing?

Thanks for any help! thumb.gif
