Q6600 @ 3.8ghz - But plenty BSOD's

Gibbo_GTI · 17 Jan 2009 at 12:18

Currently idling at 20-21 degrees C, ambient in room is 15 degrees C.

toon_mad · 17 Jan 2009 at 12:30

thats insane, ive seen the pics myself but it doesnt seem real to have such low temps

Gibbo_GTI · 17 Jan 2009 at 12:34

I've just installed RealTemp 2.90 and the tjmax has been increased to 100 from 95 in version 2.70

toon_mad · 17 Jan 2009 at 15:36

ive got 2.70, i manually set the tjmax to 90 - i think thats right?

toon_mad · 17 Jan 2009 at 17:46

another loss to the toon

just read that if you overclock the pci-e frequency from 100mhz it can help overclocks, im going to try 110mhz see if it helps..

robert.brookes@ · 17 Jan 2009 at 19:21

beinterested in the outcome toon

ive been inspired, ive got mine at 3.5 atm

toon_mad · 17 Jan 2009 at 19:29

ok, so i set the pci-e frequency to 110mhz and low and behold it did have some good, although not sure if it will have a negative effect on anything but with it set at that, im now at 3.7ghz, on a vcore of 1.540v according to cpu-z, its done prime95 since last post seems pretty stable, at least in that short time.

I also noticed setting the pci-e clock from 100mhz to 110mhz give me a couple frame per second quicker, tested on the same 3.6ghz as before.

Give it a go if you have that option, i guess like with anything, dont go crazy and set it something like 180mhz and zap your gfx card

So far so good though, im at least 4 vcore options less then i was before at 3.7ghz, but im stuck in the situation of should i pass the 1.55vore mark just for the extra 100mhz? I think i might call it a day @ 3.7ghz - its too tempting though for that extra bit

whats your setup rob? ..dont matter, just seen your sig

Gibbo_GTI · 18 Jan 2009 at 11:46

I'll give that a go and see if I can reduce my vcore. Should have my water cooling fitted sometime next week as well and the overclock big time we go

toon_mad · 18 Jan 2009 at 12:06

sweet, i would have went watercooled but i like the TRUE's too much

what kind of a overclock you looking for?

Gibbo_GTI · 18 Jan 2009 at 12:08

Over 4GHz would be sweet but will still be happy with anything over 3.6 really

toon_mad · 18 Jan 2009 at 12:26

i always said 3ghz but started getting power hungry for more

willy · 18 Jan 2009 at 13:11

What's your temp?

Gibbo_GTI · 18 Jan 2009 at 13:55

With tjmax set at 95, i'm hitting 70c during prime95 with air cooling

willy · 18 Jan 2009 at 17:27

Do you use core temp as well? I found it core temp for quad core more accurate than real temp as core temp gives the same output with everest, HWmonitor, etc

I just put up my FSB to 380 to 3.4GHz and vCore 1.443, with intelburntest hit 70c 100%. Gonna try hit 3.5GHz later if i can as when i tried with vCore 1.46250 got BSOD when did intelburntest.

toon_mad · 18 Jan 2009 at 20:06

i know you can use intel burn test, prime95 etc for stress testing - but i honestly would never have my quad running nearly 80% or higher for a long time, under load my cores reach about 47c-50c, its just my vcore is at 1.56v which has not been reccomended, its down to me if i want to increase this i know, i just wish someone would come on here and say 1.6v is fine, i can hit 3.8ghz then

willy · 18 Jan 2009 at 21:10

Well if you want someone just to say 1.6v is fine then, it is fine if you prepare for another cpu

Tbh mate, 3.7GHz on air for Q6600 is brilliant actually

Why do you think 1.6V isn't OK?

Have a look at the [URL="http://forums.overclockers.co.uk/showthread.php?t=17790550]Official SuperPi thread[/URL] and you'll see people running Q6600's with massive volts. As far as I am aware there are no reported electron migration issues with Q6600's or the older E6xx0 series CPUs. You are far more likely to damage the CPU by running too high a VTT rather than Vcore.

I said that many people on here including myself wouldn't feel that comfortable running 1.6Vcore through a 65nm chip for 24/7 usage.

I really don't want to get in your face over this, but what are basing that statement on?

Agreed, but if the load temperatures are OK and the system is stable, then what's the problem?

But based on what evidence of CPUs failing? I've got 8 machines here in my SAP test suite, all running at least 3.6GHz and all are running 1.5V plus. They literally run 100% 24/7 and none of them is showing any evidence of problems. The early G0 Q6600's had much higher Vids that the current ones and most of them need big volts to hit 3.6GHz, let alone 3.8GHz+. I've never heard of a Q6600 failing after being overclocked, or even E8x00 and Q9x00 CPUs other than the first couple that were reported on Extreme Systems.
