Q6600 overclock unstable.

NeoVo · 21 Mar 2009 at 22:09

First off, im a complete noob to overclocking, but read all guides and stuff on the forum.

System specs are in signiture.
I managed to achieve 2.587ghz, which i know is far less than the capabilities of this chip. I tried raising the fsb speed more but i had an error on the boot screen, lowering the fsb cured this.

Iv tried a variation of games, since the overclock and depsite noticing a mild performance increases, the games close within 2 minutes due to a few problems.

Iv uploaded a screenprint of coretemp + cpu-z. Il take some pics now of the bios.

Thanks in advance.

You might need to increase vcore a little bit again. Usually when you increase fsb, and find you are unstable, try increasing fsb a little bit.

Keep and eye on your temperatures though. What heatsink (cpu cooler) are you using?

Also, what speed is your RAM rated to run at?

Maybe its overheating? Did you lock the memory ratio? If not it may be corrupt drives. But im a noob sorry

Probably a memory issue.

Is the memory running far past its advertised speed, or have you unlinked it?

I have Corsair 4GB DDR2 XMS2 PC2-6400C5 which runs at timings 5-5-5-18.

My vcore in bios is set to 1.300V but on cpu-z it reflects as 1.28, is that normal?

I have a zalman 9500 LED cooler, iv ran prime, and temperatures go to 50 after about an hour.

I have them linked, could that be why?

What settings should i use for say.. a 2.7ghz overclock?

Is 85 tj max right for a B3 ?

Set up the memory divider or unlink so that on a 2.7 overclock the memory doesn't go beyond the ram speed.

Do you know how to do that?

as silly as it sounds.. no, any walkthroughs/advice?

VortexA1 · 21 Mar 2009 at 23:01

It's ok..don't worry about it everyone has to start somewhere.

I'll have a look at your mobos instructions if I can.

VortexA1 · 21 Mar 2009 at 23:07

on Bios menus - Extreme Tweaker/fsb and memory tweaker.

Memory options on there - click on unlinked and then you can put in your chosen ram speed.

i don't use unlinked cos i don't have an option on my mobo - I have to run on a ratio.

so, on there i should put the memory timings of the RAM in?

VortexA1 · 21 Mar 2009 at 23:16

no not memory timing the speed the memory is running ..try this.

ah the good old P5N-E SLi, my experience of this board is very simple whack up the cpu voltage to 1.325 set the fbs to 1333 and the ram to unlinked and whack in 667 shoudl be stable as

i remember nights on end trying all the combinations and only that one worked i do not know why but thats about it

Forget about overclocking a Q6600 on a P5N32-E SLi, it's one of the worst overclocking motherboards for quads ever manufactured. Run at stock and be happy.

I set mine @ 100. Temps are to low otherwise.

Indeed - me too on my GO but in not sure about the B3

+2

But it can be done if you use the older 1203 bios for that mobo, I did and had it at 3.2 stable.

NeoVo · 22 Mar 2009 at 15:12

Ok, i managed to get the q6600 to 3.0ghz using the settings that 'siumatfung' recommended though still experienced crashes and instability. Now running at stock speeds until i buy a new motherboard.

Was planning on going down the i7 route, but not with current prices.

Can anyone recommend a good overclocking 775 board for my q6600?
(I personally prefer asus or gigabyte).
