Heres the deal. My oc sometimes passes ibt/linx and sometimes it dont, without changing the settings in bios.... Ive been trying to stabilize it for weeks now, with no success. it doesnt crashes in games, even cpu more demanding ones... ive tried several settings in bios when it doenst passes the stress test...
My specs are:
q6600 g0 vid 1.3250 @ 3.6ghz
p5q bios 1406
teamgroup xtreem dark pc2-8500

This is what ive came up so far:

Same settings Always
400*9,
ddr's 1066 5-5-5-15 2.2v
vcore 1.50625
cpu pll 1.58
sbv 1.10 or auto
pci sata 1.50 or auto

Settings that changed:

Can anyone understand this ?? because i dont... i tried even with higher (1 notch - 1.51xxv) vcore.. but the same thing.. sometimes it passes and other times it dont with the same settings and without changing anything in bios.. :heink: :heink:
Can anyone help me please?

Splendid
Sounds like you've hit the OC limit of your chip. If you want to keep the CPU for a while, you might consider dropping the voltage, as 1.51V is pretty high for the q6600.

ok... :bounce: i think i got it :sol: already reboot twice and ran the test and it passed!!! these are the settings i changed:
cpu pll 1.64
gtl ref 0.61x
fsb term 1.32
nbv 1.30
sbv 1.10
pcie sata 1.50

I just had to change the cpu pll to higher value. thanks to another overclocker for the hint!!

Thank you for your help! :)

PPL value higher than 1.6 is extremely dangerous and the PPL is normally a bit higher than what is set. I'd watch out for any potential problems.
 
You're showing VCore Max of 1.54V on hardware monitor. I wouldn't push yoru Vcore that high, as Intel says the maximum setting is 1.5V. You could run into premature CPU death...

Also, 2 of your cores are showing temps of 75C. Intel set the thermal limit on the Q6600 at 70 or 72C as I recall. Granted you're likely not going to have 100% load on your CPU at all times, but it's something you might want to look at also.

Gratz on a stable 3.6Ghz though.

ok. you guys wont believe it, but yesterday i run ibt/linx and it didnt passed!! i thought raising the cpu pll solved it (even that i rebooted twice and run the test) but it didnt... im still with the same problem... using the same settings from the first post and with cpu pll at 1.64v this is what ive got:

Sometime it passes ibt and sometimes it dont... im desperate.. i dont know what to do more.. do you guys have any ideas?

Thanks.

hi i have a almost the same problem as you

i pass then ill try again say an hour or so later to confim its still working fine i blue screen... the way i do it fine your maxmus stable voltage that you once got before then prime 95 it over night to make sure its okay ,,, i dunno i dont get it maybe a bug in the app or something.

going to try primeing it to see the result... occt crashes after 20m, ibt/linx after 3m... the problem is that i had 8hrs stable prime large ffts at 450*6. should be just a matter of raising the multi and vcore. and maybe tweak the gtls...

Any idea guys?
