I haven't overclocked anything since my old Barton cpu in an Abit NF7 mobo, so I will need a few pointers here.

I drove down to OcUK yesterday and picked up the following:

Intel Core 2 Quad Pro Q6600
Gigabyte GA-EP45-DQ6
OCZ 2GB (2x1GB) PC2-6400C4 Dual Channel Platinum
Tuniq Tower 120

I already had the other parts at home ;)

I just loaded everything up last night and installed a few games etc. So tonight I want to overclock this to at least 3Ghz.

What do I need to do in order to overclock my new system???

TIA :)
 
My Q6600 did 4.3ghz with my P45 P5Q Deluxe on the lowest chipset voltages (1.2v FSB, 1.1v NB/MCH and 1.5v PLL).

All I had to do was up the FSB and vcore. It really was a piece of cake.

Awesome chipset with the 65nm quads.

whoa can it do that on a p35 board or did the p45 made a difference?
 
P45 made a hell of a difference. P35 couldn't get it over 4.05ghz even with the chipset voltages set sky high.

With serious water no doubt ?
 
Of course.

But I was taking more about forgeting about juggling the chipset voltages and just concentrating on vcore.

Tho 3ghz should only need the stock vcore.
 
Just before I start my overclocking I have noticed in CPU-Z it shows my system as running at this

Core Speed - 1600.1Mhz
Multiplier - 6
Bus Speed - 266.7Mhz
Rated FSB - 1066.7Mhz

Does this look right, or is sumik wrong :confused:

looks fine, mystic. You have Speedstep enabled (C1E, EIST) in the BIOS. This drops your multi to 6 when idle, and back to 9 (or whatever you've chosen in BIOS) under load.

I prefer to leave this enabled, but opinions differ.

You need 333.33 * 9 to hit 3.0GHz - a lot of boards will do this on Auto/Stock volts. I'd recommend starting from 300 - in increments of your own choosing. Bashing with some memtest, prime95, etc. For Prime95 use 25.4 or higher, and don't forget to select Round-off Checking on the Advanced menu.

Best of luck, mate :).
 
I just tried hitting 300 * 9 with everything at Stock/ Auto volts and it told me that my system was unstable when I went back into the Bios.

Not a good start :(

He is a picture of my BIOS, can you assist me in what I need to change in order to start hitting at least 3Ghz :)

you might want to start by setting vDimm (DRAM Voltage) to 2.1v - at stock everything else. and run memtest on all your ram. Throw in a Prime95 test on small ffts, to ensure that you're at least starting out with a stable platform.

build from there. you may have to come off Auto CPU vCore - and I'm not sure about the Turbo setting - maybe knock it off while getting to your target o/c?
 
The first thing to do is set the System Memory Multiplier to x2.0. It will drop the memory speed below its rated speed, but it'll get closer as you raise your FSB.

Set Performance Enhance to Standard (or normal depending on what option it gives you). You can try tweaking it after you've clocked the CPU.

Set DRAM Voltage to 2.1v/+0.3v.

Now those options should take your memory out of the equation.

Then set PCI Express to 101mhz, CPU Vcore to 1.325v, and set CPU Termination, CPU PLL and MCH Core to their lowest settings (probably one setting above Auto).

I would expect you to get 3ghz on those settings. If not then up the CPU Vcore to 1.35v. In theory you shouldn't need to increase the other voltages.

Cheers for that, but do I leave the memory settings alone after I up the voltage?
 
upping vDimm is only necessary because 1.8v is usually not enough to do more than booting into Windows (if you're lucky!)

Cob has given a pretty comprehensive outline of the preliminary steps. I'd be inclined to follow his steps to the letter, and then run some stability tests. As he says, you may need to tweak some volts, but hopefully nothing more than a minor bump on vCore.

I have tried all those settings and it did not want to know, I had to reset the Cmos. So either I am doing sumik really back, or I have got a dud cpu :confused:
