Intel Core 2 Duo E6600 Conroe 2.4GHz
GIGABYTE GA-P35-DQ6 Latest BIOS F9b Broken and replaced with Asus P5Q p45 chipset
EVGA 320-P2-N811-AR GeForce 8800 GTS 320MB
G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 x2 total of 8gb of memory

My old Gigabyte P35-DQ6 motherboard just died and I replaced it with the Asus P5Q motherboard. With my old setup I was able to over clock it to 3.2ghz stable with FSB at 400 * 8 multiplier.

When I try to do the same with my new board I can't see to get it pass 333mhz FSB. The BIOS on the Asus board doesn't seem to have a lot of overclocking features such as the Gigabyte board IMO. Do I need to hit CTRL F1 to enable more overclocking features just like the gigabyte board?

Can some guide me on what to enable or disable in my Asus BIOS to achieve my old overclock using the same setup? Should I leave everything in the AI tweaker on AUTO and just raise the FSB? Also the highest multiplier for my e6600 core 2 duo is 9. I assume that my multiplier for this process is locked? I can only decrease the multiplier.

Thank you!

I have a P5Q-E board w/Q6600

Yes; highest mutiplier for Q6600 is 9

To unlock auto options which I presume you have already done is set the first option in AI Tweeker to manual. I have a bad memory so I forget what it is called and I'm at work so I can't look it up for you.

To get mine to 3.2GHs all I did was set multiplier to 9 and FSB to 357MHs. I left CPU voltage on auto. At 357 this automatically set my ram speed to 715 (357x2). I set my ram to the correct specs 4-4-4-12 at 1.9v. I also set PCI to 100.

I ran Prime95 for 23 hrs with no errors. CPU-Z showed vcore voltage at 1.4v.

I later went in and started backing off my voltage and if my memory serves me right I quit at 1.3v

Hope this helps

olddman: what type of memory are you using?

I am using PC6400 DDR800, I will try it when I get home and set it to the same FSB you are using 357*9

Should I manually set the voltage? I assume I should set the PCI E to 100mhz right? What is that by the way? Is that the speed for my Video card? I recall on my old Gigabyte board I set it to 102 mhz.

I use G.SKILL 4GB (2x2GB) DDR2 800(PC2 6400). Your timings and voltage should be on a chip. If I remember right the default voltage in the bios was set to 1.8v.

I set the PCIe to 100MHs because thats what was recommended in just about all the threads on here. This was my first overclock attempt and I kinda followed what was recomended. But yes, that should be the speed of the video card and you manually set it so it doesn't increase with the FSB of the processor.

It seems that most folks will reccoment you setting the CPU voltage manually but I left it on Auto. When I booted up and looked at the reading in CPU-Z it had 1.4v so I new I was not maxxed out but at the same time I figured it was high for 3.2GHs. I went ahead and ran Prime95 for 23 hrs. Everything was ok. No errors. I then went back in and lower my voltage a little at a time. I then tried to post. If it did I went back in and lower it a little more till I got to 1.3v. I thought this was a good voltage so I left it there. I may have been able to go lower but didn't try. I then booted back up and ran Prime95 again for about 22 hrs. No errors so I left everything at those settings.

Here again if remember right, temps only maxxed out at 62-62-55-57 so I thought i had a good Overclock and left everything at that.

I have the same memory you are using. I will try it when I get home and thank you for your help. So it's actually much easier to overclock with the ASus board since everything is set on Auto as with the gigabyte you would have to change all the settings

that's good OCing advice in general. use the auto settings and since they always run high start there with manual settings and work your way down.

i'm working on OCing my 8500, and have been trying to get some advice on where to start, but that makes so much sense!

Thank you Spidy.

This was my first attempt at building and overclocking. I did a lot of reading and took from all the threads what I thought would apply to me and then used what I thought was some common sense and proceeded. I could not have done it without all the excellent, wise posters on here.
