Hi guys, i'm trying to make my i7 stable at 4.1ghz.

i can play every game, run vantage and just use it daily without any problems.

To me this seems like a stable system, but when i try to run prime or linx, i get blue screens after 45 minutes or so?

i've noticed how some people run prime and get errors, so it tells them it is not stable, but what does a blue screen mean?

the vcore is at 1.39v, and get no hotter than 82c under load, highest i've seen under gaming is 77c.

idle is around 40-42c

specs in my sig

Cheers
 
I'm no i7 expert but those temps seem a bit high mate ?
I run my e8400 with 1.375V @ 4ghz and my temps never go above 60 at full load
As far as your blue screens go it could be any number of issues really It took me a long time and many blue screens to get my bios totally stable @ 4ghz
 
Prime and IBT/Linx can't always stop before they cause an error. Your temps are fine, people on here have run much hotter (90Cs).
 
I'm in a similar situation mate, my e8500 can sit at 4.5ghz all day, encode stuff, game, you name it. However, within just a few minutes of prime I get errors.
 
They run hot - mine loads at 78c.

Blue screens are usually caused by memory or driver error....what voltage/speed/timings is your memory running at?
 
I'm at the office, so from the top of my head:
1563mhz
8:8:8:24
1.64v

I always assumed it was my voltages, the cpu not getting enough juice when it runs for a long time under load.

I can run it at 4.1 ghz with 1.32v, no problem, but just found that under prime, i could run longer without blue screens with a higher vcore.

The downside is with higher volts, the temps go up, and i'm not comfortable seeing it hit 90+c

i don't think the bluescreens are temp related because it seems to bluescreen around 80c after a while, which is definitely within the chips capability.

For reference, I had it overclocked to 3.6ghz with HT and it was prime stable for 15hours, with temps hitting 90c

I should have mentioned this before, but HT is off, very hot with it on, and fails the first vantage CPU test with it on.

Could I increase my QPI voltage, I’m not too sure what it is, but around 1.31v I guess
 
going by the older intel platform but that seems rather hot don't it :S unless I7 cpus can handle it which i hope they can or early grave :o

I have a Q9550 as shown in specs under full hard load it don't go *that* high and i hate to see it go past 70c anyway even if its only on one core

I think it's important to note that he has 2 X 280 GTXs in that case which would be pumping out ALLOT of heat.
