Failed Prime just short of 3hours, well PC blue screened after 2hours 55minutes

Load temps were 56-58c across 4 cores

That was at 4.1ghz :(

more volts needed or?
Normally BSOD = not enough voltage, but not after 3hours of prime, normally instant!

It can be a real pain getting the last few MHz, had loads of 3hrs+ at 4GHz just to crash out. Change a setting and start again, upping the voltage doesn't always help. Makes it worse sometimes. Moving to water I finally got 4.05GHz @ 1.61v with a cold night. 3.8Ghz was easy @ 1.48v (1.57v on air). Its an early week chip, it hated the extra 200MHz for 4 gig, temps were much higher. The GTLref helped me in the end.

1.488v under load

3870mhz

54-54-56-56 after 45minutes of Prime. Temps will stay at that for hours, just hope it doesn't BSOD or I'm going to have to faff around in the BIOS!

850/2125/2200 on your card, that's an absolute beast!

Mine was stable on air at 800/2100/2000 but under water it seems to get just below that strangely! Definitely can't hit 850/2125 though with this Asus one Ive got !

1.48v exactly the same as mine, volt modded my board to get rid of the droop. Temps are similar to mine as well, although opened my window after 8hrs to see the result and it dropped to 28C load:eek: Funnily enough my GTS is an Asus, still on the stock cooling. Temps don't seem to hold them back, I'd volt mod it, but I'm going to chop it in soon.

I get a straight reset in prime when at 4Ghz :( this is with my Asus P5K Premium.

Does that have a GTLref setting? I had the board but can't remember. On my IP35 Pro, gradually changing the GTLref from 67% to 70% (+71% was worse) stopped it instant resetting when prime started at 4GHz. I had the Maximus Formula, but that stopped at 63% and suffered instant restarts with this chip at 4Ghz as well.

run all my clocks @ 5-5-5-23 Timmings... that way you no if it fails is certainly not the RAM, can always tighten it up after once you no that the CPU is stable
 
Currently clocking my Quad, not going for it straight away - wanting to play with the board a bit. Nice having the option of separate die GTLREF settings and NB GTLREF settings. :D

Straight in at 3.6 without a sweat which I expected anyway, but GTLREF settings have pretty much let me keep all voltages down to default when it comes to VTT and vMCH. vCore I'm working on getting down too.

After that, Ill go for gold and once I get some separate sinks and NB block I'll lower performance level and phase adjusts :)

well if increasing vcore is having no effect i found raising my FSB Termination voltage 1 notch helped a bit :)

Must admit Ive left pretty much everything on auto, will try that :)
have been chatting to Devious and will be trying his bios settings out.
It my just need more vcore though.

Hum, cant get to my pc atm, but I dont recall it having a GTL ref voltage setting though.
 
I'm happy enough with these for now, mostly trade off for lower temps rather than higher clock speed.

CPU - Q6600
Revison - G0
FPO# - Unknown at this time (bought OEM version)
Clockspeed - 3.33Ghz (370x9)
Vcore (under load in windows) - 1.25v
Vid (core temp) - 1.2375
Motherboard - Abit IP35 Pro
Cooling - Arctic Freezer 7 Pro
Thermal paste used - Arctic Silver 5
CPU Temp - 60 under load
