q6600 OCing probs

steveg123 · Dec 15, 2008

hello there i just tried to oc my q6600 from stock 2.4 to fsb333x9(3.0ghz magic number for q6600 go) in easytune6 and windows froze and i had to reset my comp so i went back into bios and got a red error box saying my pc was unstable cos of oc,voltage change etc.so i tried 300x9 instead in bios,saved change and exited bios and the gigabyte mobo rebooted as usual as it does when changing a cpu setting but this time it powered up and off continuously each time for a second or two over and over until i turned it off by psu switch at back.the cpu is reading 1.1625 in real temp and core temp,cpuz etc.i know every cpu is different but common hearsay is that the go model can be put upto 3ghz piece of cake so what am i doing wrong here? i been reading about and read mention of ram timings needing adjusting?

Try changing the FSB from the default of 266 MHz to 400 MHz in the BIOS (don't use Easy Tune for the time being), change the CPU Clock Ratio to 7.5 (400 MHz FSB w/ a 7.5 mult. = 3.0 GHz clock), change the NB Strap (MCH Frequency Latch) to 400, and change the System Memory Multiplier to 2.66 = Memory Frequency (Mhz) of 1066.

steveg123 · Dec 16, 2008

thanks for the reply redduc.ive managed to change all the settings u said except how do i change the cpu clock ratio to a 7.5? i cant input a decimal in the box and putting 75 doesnt work either.sorry for being such a noobie.

just had a browse around google and apparently cos my q6600 is a 65nm size and not 45nm it hasnt got the option to fine adjust the clock ratio so i cant get a 7.5 on the multiplier only a 6 7 8 or 9.

redduc900 · Dec 16, 2008

Sorry, my mistake. Change the multiplier to either 7 or 8 w/ the same settings I posted above. With a multiplier of 8 (400 MHz x 8 = 3.2 GHz), you may have to increase the Vcore somewhat depending on the VID of your chip.

steveg123 · Dec 16, 2008

i think my vid is at 1.3250 is that high enough to go for the 3.2ghz? 8x400mhz

redduc900 · Dec 16, 2008

It's a high VID, but 3.2 GHz shouldn't be a problem... lower VID chips normally OC better than a higher VID chip.

steveg123 · Dec 16, 2008

well i gave it a go on 7x400 and that seemed fine so i tried 8x400 and it worked but when i loaded up crysis warhead i was getting all weird artifacts in the game so i put it back down to 7x400 and it seems solid there,game runs perfect maxed out.one question tho would my system be more stable with a 333 fsb or 400? disreguarding the cpu speed

jjw0782 · Dec 16, 2008

umm from my knowledge the fsb was the cpu speed times the multiplier. everything runs different for everyone. its safer in the long run to keep your vcore at the lowest possible setting to get the most life out of the chip. i run mine at 333fsb 24/7 with no issues.

CPU clock speed = FSB x multiplier.

If I had the choice, I would go for the 400 MHz FSB... it's not really a matter of stability, in regards to either an FSB of 333 or 400 at the same clock. In your case w/ Crysis for example, the issue isn't w/ the difference in FSB, but instead the difference in clock speed (2.8 GHz vs 3.2 GHz). Since the VID of your quad is 1.3250 at the default 2.4 GHz clock, a clock speed of 3.2 GHz (an 800 MHz overclock) will very likely require more Vcore / Vcc. Other voltages like PLL, VTT, and vNB for example can more than likely be left at their default voltages because of the somewhat low 400 MHz FSB. On the other hand, since you have 4 x 1GB sticks of RAM installed (as compared to 1 x 2GB or 2 x 2GB sticks), you might need to increase the vNB somewhat, but that should be about it.

steveg123 · Dec 17, 2008

thanks redduc.if i went for the 3.2ghz 400x8 option can you suggest some settings to change to keep it stable? i was getting around 38-40 celcius at stock settings in warhead and 45ish with 2.8ghz.the vid of the chip seems to be 1.1625 idle and it jumps up to the 1.325 setting when its doing stuff,is that normal?

redduc900 · Dec 17, 2008

Yes that's normal... 1.1625v is what's called the Min. VID, and 1.3250 is the Max. VID. Since you have EIST (SpeedStep) / C1E enabled in the BIOS, Min. VID is the voltage you'll see when the CPU is idling, and Max. VID is the voltage when the CPU is under a load (like when playing a game, running Prime, or when running SuperPI for example). If EIST / C1E were disabled in the BIOS, then the voltage you would see at all times (discounting Vdroop / Vdrop) would be the Max. VID of 1.3250v.

Post up all of your current voltages using this tempate for the DS4...

Give these settings a try for 400 x 8 = 3.2 GHz...

Leave these four settings at default (for the time being):
CPU Clock Drive: 800 mv
PCI Express Clock Drive: 900 mv
CPU Clock Skew (ps): 0 ps
MCH Clock Skew (ps): 0 ps

Performance Enhance: Normal

Use these two settings for the time being...
Memory Multiplier: 2.0
DRAM Frequency: 800 MHz

Leave all RAM sub-timings on AUTO for the time being (SPD)

CPU Vcore: 1.4 - 1.42v (depending on the amount of Vdroop, shoot for 1.4v in Windows - this is only temporary)
CPU Termination: 1.25 - 1.30v (considering 4 x 1GB sticks of RAM)
CPU PLL: 1.500v (leave at default)

Leave CPU vRef's at default for the time being
CPU Reference1: 0.760v
CPU Reference2: 0.800v

MCH Core: 1.3 - 1.4v (just for the time being)

Leave NB vREF's at default for the time being
MCH Reference: 0.760v
MCH/DRAM Ref: 0.900v

... and there's no need to adjust SB voltages
ICH I/O……………….....1.500V............: v
ICH Core…………...……1.100V............: v

steveg123 · Dec 20, 2008

ok i changed all the settings you suggested redduc,just to note that the cpu clock drive and pci express clock drive settings were at 700 default,was it still ok to change them both to 800 and 900 respectively? anyway things seem ok at these settings so far

redduc900 · Dec 20, 2008

Yes, leave the frequency amplitudes for the CPU/NB and NB/PCI-E buses at 800mV and 900mV respectively. Make sure to run Prime small FFTs at these settings before calling it stable, then we can move on to increasing the clock speed and DRAM frequency.

steveg123 · Dec 20, 2008

ok redduc i know i havnt ran it properly but i ran prime 95 small ftts for bout 20 mins and seemed alright for that short time although temps seemed a bit high in the pic below or is that fine for those temps?.will run prime properly and see what happens.crysis hasnt glitched on me yet

redduc900 · Dec 20, 2008

Those core temp's aren't that bad (low 60'sC), considering the 1.4 - 1.42 Vcc being applied. When the core temp's reach 70 - 75C, then it's time to start worrying about your cooling. What are you using for a HSF at the moment, and how's your case cooling?

Looks like the PSU may not be enough, with a higher core frequency! (400x8 vs. 400x7) just increased the core frequency, thus it looks like the 65 nm chip may be taking power from your video card.

Your issue don't look like the Vcore. It looks more like the PSU isn't enough. Because all you did was raise the core frequency.

Your response totally confuses me...

How did you come to this conclusion? Why is it taking power from the video card? Usually when you raise the core freq you need to raise the vcore...

ive got a ocz vendetta 1 sitting on the cpu and i have four case fans in the case,the cosmos has a nice vent finish on the top where i have two top fans venting the hot air out the grills
