Hi Folks,

I have just upgraded my pc and I'm looking to squeeze a little more power out of it while keeping it stable! My spec is as follows;

Q6600 g0 @ 2.4ghz
Arctic Cooler
Asus p5n-e SLI
4gb Ocz platinum ddr2 6400
7800gtx x2 SLI
Coolermaster 620w modular
Raptor hdd's
akasa eclipse case (great cooling)

I would like to squeeze about 3.0ghz out of it if possible? My temperature for the CPU is low 30's ok a 1.25 vcore.

Is it just a case of increasing the FSB and upping the vcore upon a crash? Do I leave the memory Fsb unlinked with the CPU or should the be increasing together?

I assume I'm just aiming for fsb1333 to give 3.0ghz but as I'm sure you can tell things have changed a little since I overclocked my athlon xp 2500 to 3200 speeds.

Any help would be appreciated!
thanks
 
Leaving the RAM linked with the CPU will mean that it will be underclocked so shouldnt be an issue when you raise the FSB. If you leave it this way then you wont start clocking your RAM till you hit 400FSB, which with the standard mulitplier on the Q6600 being 9, would be 3.6GHz.

To hit your 3.0GHz speed, i wouldnt have thought you would need much of an increase, if at all, to the vcore, so you could go up in stages all the way to 333FSB or just go straight in at 333.

As you say, if there is a crash during stress testing then you would need to increase the vcore slightly until it stops crashing.
 
cheers mate....

Could anyone shed any light on this fsb buisness? Where does the 1333 come from as opposed to the standard 333 Fsb???

I see what your saying with regard to the ram being rated to 400fsb so I won't have to worry about that. But I'm sure when I leave the fsb linked it ups my ram to 1333fsb???

Im a little confused...
 
1333FSB means 333mmhz quad pumped (x4) for intel CPUs. Also, linking RAM would give 333x2=666 (or DDR2-667 as they like to call it). It's x2 as its DDR meaning Double Data Rate.
 
Yep, your board has official support for both 1333fsb CPU's and 800Mhz DDR2 so it's no strain for your board whatsoever. You would need to set the divider to 5/6 (333/400)
 
I used a lower multiplier, dropped it by one, which meant i could hit 400 mhz on a 1:1 ratio and achived 3.2ghz for my quad, i had to up the vcore about 2 notches to get it stable..

I found this OC worked better for me decent OC 1:1 ratio and a cpu that doesnt go over 60 degrees.
 
I got my q6600 clocked to 3.0 by upping the FSB to 333 and changing the memory multiplier to 2.4. Didnt have to touch the Vcore at all.
 
Ok guys some results...... Or not as the case may be......

I tried upping the FSB of the cpu to 333 and ran it 1:1 with the memory clocked down at 333 also. This failed to boot so i upped the vcore to 1.4v and it still refused to boot!

I then tried running the CPU FSB at 333 and the Memory at 400..... Same problem im affraid. My computer would hang just before booting into windows.

Any ideas? Does this mean i cant get 3.0ghz out of my cpu?

Cheers
 
P5N-E SLI has terrible VRM so not the best board to oc a Q6600, a lot of people can't get above 3Ghz on this board IIRC. I used to have the same board and this is the only reason I side stepped to a P5B Deluxe.

It's not your cpu a G0 is more than capable of reaching 3Ghz and a lot more.
 
small result....

anything over this seems to instantly crash......
