1t cr at near as damn it ddr1000? certainly doesn’t seem to be affecting your oc!
I would be surprised if you could tighten the timing.

I would have thought you would be able to run 366 x 9, why you are hitting a wall at 3ghz on that 9 multi is a bit of a mystery to me. could be an nb strap issue maybe.

i might have another try with the x 9 multi. but i am happy enough with the 3.3 with the x8 for now.
i was told CR 1T is faster than 2T, but to be honest,when i put the ram into my mobo. the mobo set the ram at 1T. i didn't.

with my Q I tend to just try and keep temps under 81C

I've had no stability issues up to 81C

i have a b3 Q6600. they have a lower tjmax than the G0's
at 75.C in occt the linpac test will fail, as cpu is too hot

nice C64 :)
also good gflops, the last time i only got average of 39. :(
will have to try that free ram setting next time, that wingzero30 mentioned in another thread.

I have also not got around to cleaning my case yet.
hopefully if a get some of that C Diamond24/Perihelion4gm in the giveaway thread, it will give me a reason to give it a good clearout ;)
 
Decided to play around with my q6600. Normally I keep it at around 3.4ghz

Not bad for a cheap mobo and ram :P

The OC isn't very stable atm so I'll play around with it some more over the weekend. I've also managed to get to 3.96ghz but that's even less stable. Unfortuantely that's the highest OC my mobo will be able to do - voltage control maxes out at 1.6v
 
Installed my q6600 GO low vid chip yesterday, have it sitting at 3.2ghz with little vcore increase (think just over 1.25), seems stable but anymore one of the core fails in prime95. Also now the temps are idling in the high 30's, 50-55 in bad company 2, 60 or so in prime95. Might try for more later.

edit: currently at 3.4ghz with 1.31 vcore, will see how it is in prime,

Will 378x9 be the same performance as 425x8?

iirc the x8 is slightly faster than the x9 as you are running at a higher FSB.
also run intel burn test (IBT) this is better for testing stability than prime.
just make sure you adjust the threads to 4 and custom ram (use all the free memor) chech some of wingzero's posts above

if 3.4 is unstable, try adding another notch of volts
 
Yeah 1 core stopped working so added more volts, i tried it at x8 with 425 and it wouldnt even boot, maybe my ram (geil ultra) couldnt take the extra 50mhz :s.

Is it worth spending time trying to get x8 to work or will the difference be unnoticeable? So 3.4ghz at x9 will still be faster than say 3.2ghz at x8?

thanks.

not necessarily

depends on the mobo / chipset

if P965 - well on a P5B Deluxe Anyway >400mhz goes to a lower/slower strap for stability

therefore 380x9 for instance is a lot faster than 410 or whatever it works out at x8

:)
 
15 minutes now on prime95 at 3.4ghz, vcore is 1.36 which is still pretty low, although the temps are hovering between 60 and 65 so its a little toasty, the fenrir evo fan kicks in at full speed around 65 though which then brings it back down to 60 :) seems stable so far but will leave it on for half hour or so. I dont think there will be any performance gains from pushing it higher than 3.4, although i know the previous owner of this particular chip hit 4ghz :p

edit: For some reason 3.4ghz makes my graphics driver stop responding in games, but any lower its fine, why would it cause this? :confused: Could 4 x 1gb sticks of ram or NB volts be causing problems?

Been fiddling about today and managed to get 3.8GHz (423x9) running stable with speedstep thingy enabled! Automatically clocks itself down to around 2.6Ghz. Keeping my 4GHz clock and having that on just causes random bsod's unfortunately. Good for saving power and excess heat.

Settings on P45 Asus Maximus Formula with air cooled chipset and watercooled cpu/gpu.
CPU Core : 1.42v
NB : 1.20v
SB : 1.12v
CPU VTT : 1.29v
CP PLL : 1.70v

According to Everest in an ambient of 22c idle temps are;
Cores 31/30/22/21
NB and SB both 46c
Mobo 38c

Using Everest on stability test i'm showing 48/48/42/42 after about 30 mins testing (holds it at 3.8)

Who needs that extra 200mhz, it just causes slight issues and has no real world effect on performance. I can bench at 4ghz but for me it's just not worth that hassle to fine tune, not to mention the majority of time my cpu is practically idle! It works out having that speedstep enabled I save anything upto 15w on idle alone over running at 4GHz 24/7. Power savings wont be as much at full load, perhaps only 2-3w max.
 
My sentiments exactly realscot. I have [email protected] and going to 3.6Ghz isn't worth it for 2-4fps extra in games with the downside being more electricity consumption and higher temps.

Sure in benches going from 3.4GHz to 3.6Ghz will result in slightly better results but there won't be any noticeable improvements in real world usage especially in games.

I think I can go upto 3.5GHz easily on air cooling but again I am more than happy with [email protected] as it is 1GHz stable overclock and does everything nicely:).
 
reverted back to 3.2ghz, wasnt happy at 65c playing bad company 2, the thermal paste was put on perfectly and the cooler is good (Titan Fenrir Evo), does the paste need time to set? 3.2ghz is fine it idles in the 30's and is between 50-60 on full load.

3.2GHz is fine. It is 800MHz extra speed over the stock speed. What thermal paste are you using? It seems most Q6600 users run at 3.2Ghz, with some at 3.4Ghz and few at 3.6Ghz. After 3.6Ghz it is only a very tiny minority who run in the 3.6Ghz-4.0Ghz range. This is what I termed the Q6600 overclocks:).

[email protected] (stock speed)
[email protected] moderate overclock
[email protected] good overclock
[email protected] high overclock
[email protected] very high overclock
[email protected] extreme overclock
[email protected]+ insane overclock
