Safe Overclock for my set-up?

EagleOC · 23 Dec 2007 at 21:50

Can someone give me an idea of what settings I need to change in order to (safely) overclock by machine?

Yes, I've read the theory and I'm still none the wiser. :confused:

Just about to install Call of Duty 4 and I want the best possible performance out of it!

• Q6600 G0 (2.4 stock)
• P5K-E WiFi
• 4Gb Corsair 6400
• BFG OC2 8800GT
• Corsair 620W PSU
• Vista 64 Ultimate

depends on your definition of "safe"

but should do 3 - 3.2 on stock volts... enter bios go to jumper free config enable manual overclocking (AI or something they call it) assumming your Ram is rated @ 800mhz set your FSB to 400 and CPU multiplier to 8.. set your vcore to 1.35v save and exit... load into windows and run prime95 (keeping an eye on temps no higher than 70c) used to run mine on stock cooler on those settings.

let prime run for an hour if it fails go back into the bios and drop your memory timmings and try again.. if it still fails raise the vcore by the minium amount and try again.. keep doing this until its stable

'Safe' to me just means faster with no danger of killing anything.

...assumming your Ram is rated @ 800mhz

Sorry, it's 6400MHz. Will those settings still apply?

[edit] how the f* do you get 4GHz on air! Nah, don't tell me.

its 6400 RAM which should be 800mhz rated so yes

4ghz took and open window and help of mother nature

but 3.906 was doable with this

Now I's confused. :eek:

6400 is the "type" of ram and is rated @ 800mhz

Lol. Of course!

Thanks for the tips.

you would have to try very hard to break it

On that machine at stock you could run CoD4 on max settings with 4x AA / 16x AF and not get any slowdowns

Ok, had a dig around and...

FSB = 400 (changed ok)
CPU Mult to 8 (can't find this setting - are Intel's locked?)
VCore to 1.35v (is this 'CPU voltage'?)

My FSB is currently 1066MHz... :confused:

2 secs let me just go check my bios

Ok you will have to excuse the flash on these pics

AI Overclocking: Manual
CPU Ratio Control: Manual
Ratio CMOS Setting: *8
FSB Fequency: 400

RAM: Whilst clocking set the RAM to 5-5-5-23 you can tighten these up after

All you need worry about is

CPU Voltage: 1.35v
CPU Voltage Dampner: Enabled

When you run the prime95 to stress test the setup keep a close eye on the load temps.. download coretemp to do this... 1.35v from memory is a little high for the clock and might produce you so high temps on full load... this can always be reduced if your temps are going over 65/70c
