p5k-e Q6600 OC Help please

Cheers for the advice Pneumonic, I'll give that a go tonight when I get home or maybe at the weekend, given there is beer needing to be drunk :)

I'd hoped to get to 3.6 as this chip doesn't seem to need much vcore for 3.4 as far as I can tell. I think 1.5v on the core may well push the temps well above 70C but I'll try it and let you know, I think I'll disable the Q-control of the CPU fan in the bios and let it run at 100% for this test as it never seems to spin up that much with Q-control turned on even when the core hits >60C.

I'm running 2 sticks of this - http://www.overclockers.co.uk/showproduct.php?prodid=MY-072-OC&groupid=701&catid=8&subcat=813
 
what happens with your PC when you try for 3.6?

Annoyingly since trying for 3.6 I seem to get a random BSOD occasionally when rebooting my PC, a complete power-off cures this though :(

It does look like I got one of the higher VID chips, which is what I'd hoped I wouldn't get and kind of knew I would lol!

I'll try the 9x multi again, but (and this may be down to me being new to C2D clocking) I couldn't get it to work when trying any variation of OC with the 9x multi when I first started out. Will try to get some OC'ing today following yours and Pneumonic's advice, cheers.

Wonder why that was then? There is no reason that I am aware of where you can't overclock a chip using stock multi but can overclock it if you drop the multi?

Most likely my fault :o

Hey there, i have the exact same setup as you, great minds and all that. Have you tried running 440mhz fsb?

Not yet but I will do later today.

Have you got your ram to boot in dual channel?

Yep both running in the yellow slots.

sepulchre if you drop your multi to x6 and test to find the motheboards max FSB. (Save all your previous OC settings in the OC profile) and start the OC fresh using the x6 multi

can you post back your findings m8

Will do m8, just back after a days shopping with the wife :( and wont now get to do any clocking until tomorrow, will let you know then.
 
Found a bit of time (read as wife not ready yet!) So I'm running through the suggestions in this thread one at a time, first up Pneumonic's..

(Speedstep or whatever its called is disabled for the moment, CPU fan under bios control)

Ambient Temp - 23C

Idle core temp - 47-47-44-46.
Idle vcore - 1.480

Load under Prime after 15 mins - 71-71-69-69
Load vcore - 1.456

So that looks OK but I will need to dtop the vcore and tighten the ram timmings then do a full prime test.

After applying the bios settings I got the now comon BSOD stop code 0x00000005, a full power off at the psu seems to sort this but it is getting annoying, doesnt seem to happen when I boot to vista though :confused:

Next up Big.Wayne... x9 multi

Loaded up my 3.4Ghz OC profile and made the following changes -

9 x 378 - 3.4Ghz
All other settings on auto
Ram - 5-5-5-15 @ 2v
Vcore - 1.375

Booted up fine with a 9x multi at 3.4Ghz so it must have been me being a dougnut :D

Temps after 15 mins of prime -

Idle core temp - 40-42-37-40
Idle vcore - 1.352

Load under Prime after 15 mins - 61-61-59-59
Load vcore - 1.336

9x390 - 3.51Ghz
Vcore - 1.4125

Idle core temp - 43-44-40-43
Idle vcore - 1.392

Load under Prime after 15 mins - 67-67-65-65
Load vcore - 1.376

Thats about all I've got time to do now. I'll push further tomorrow and find the max FSB as well, got to go out again now though so will leave the PC priming at 3.5Ghz :D

Cheers fellas!

edit for HEX - I'm also on 0503, not bothered to update it yet as I couldn't get an answer on what the best bios to update to was.

edit 2 - no BSOD's using a 9 x multi with a lower FSB, might be on to something here??

Im not sure you would be reaching the boards limit as many people have had these well past 500fsb. Mine is sitting at 445x8 atm and will run 455 1:1 with a 7 multi. It is strange it doesnt like a different multi though.

I think it may be my memory rather than the board, or rather the combination of settings I'm running.

update: Prime has now run for 5 hours without error sitting at 66-66-65-65, I'll leave it going until the morning then up the fsb further.
 
I've got it now at 3.51Ghz prime stable for 13 hours :D Pushing a little further to 3.55Ghz (9x 395) after running prime for about 5 mins the PC just blackscreened and shutdown, temps at the time were 68C. Going to change a few settings and try again.

Well no matter what I vcore I select I'm getting a BSOD at anything above 9 x 395, so maybe 3.5Ghz will be my limit, still I'm very happy with that :D

Will find the max FSB later today...

x9 multi is fine up to 3.51Ghz m8, still not had a chance to work out the max fsb, sorry will do it just not had the time to put aside to get it done yet :(
 
I wish I'd been fortunate enough to pick up a low VID chip.....sniff lol

Meant to add this earlier :)

this sounds crazy, but 3.5 on a 9x multi feels slower in games than 3.4 on an 8x multi, would the higher fsb be better for gaming?
 
lol, with the number of reboots I've had between trying to sort out my front panel audio connectors no... cant seem to get my mic and headphone socket to work under vista, works fine under XP ??
 
As I understand it (and this is especially true of data hungry quads) if you achieve the same clock frequency then using a lower multi and higher FSB is preferable to a higher multi and lower FSB in performance terms as there is more data travelling to the processor across the fsb, although this does put more strain on the motherboard. Having said all that I could well be wrong :D
