Hi there,

I can get my 2600K (hyperthreading off) to 4.5GHz easily at about 1.3v and it runs Prime successfully.

I currently have it running at 4.8 @ 1.4 using the settings from this guide:

Unfortunately I always BLOD when running Prime, sometimes after a few minutes or up to an hour in. However so far my pc has run fine as long as I don't stress test it. I can play BF3 (probably the most demanding thing my pc will do apart from Prime) for a few hours. Maximum temp is 62 degrees with BF3, highest seen so far in Prime is 83.

My question is should I just stay at 4.8 which is stable for everyday use even though my pc can't cope with Prime or drop back to a completely stable 4.5? Also do you think my voltage is a bit high @ 1.4, temps seem to be ok.

Many thanks!
 
Prime95 proves that your processor functions correctly as a processor under the heaviest of loads.

Why run a processor unstably and with really high voltages just to get an extra 5-10% performance? you are not going to notice the difference outside of benchmarks and if you do you're looking too hard.

Also why turn off Hyperthreading when you've payed sixty odd quid for it?

+1 this makes sense to me
 
Prime95 is likely causing a BSOD at the moment another process kicks in. This will decrease overall load and voltage momentarily to a level your processor isn't happy with. Just because it doesn't appear to have issues during normal use doesn't mean it's stable.

Corrupted files are a strong possibility with an unstable machine. I'm certain it's why many overclockers find a re-installation of Windows solves their issues in the short term.
 
Put it to 4.5ghz because you won't notice a difference unless benchmarking.
Put it up if you want to bench your rig and get the best clock you can but 24/7 4.5 is more than enough

Clocking above your stable is only for bench tests and not for daily use

It might not crash running BF3 but if you run an unstable processor you're likely heading for future trouble's

I have a 2700k running @4.5GHz 24/7 fully prime stable (hyperthreading on) been no trouble at all for nearly 12 months now

Can bench @ 5.4GHz (hyperthreading off)

Top 3 Sandy Bridge 2700K
debs3759 5.500GHz - 6.800s 2700K
Cammy5477 5.487GHz - 6.801s 2700K
Wazz-1 5.421GHz - 6.900s 2700K

hehe wazz Im beating you :-)
 
Ha Ha yes fair play, must have been that extra .1 volt you put through it!:p
I see you have three chips on the board now, well done mate
