I5 2500k DOWNCLOCKS DURING STRESS TEST???

post #1 of 21
Thread Starter 
Ok so pretty much what i stated in the title, i'm trying to overclock my cpu to around 4.6ghz-4.8ghz but my main problem is when i stress test it downclocks from say 4.8ghz to 4ghz. I toyed around in the UEFI bios but nothing. Oh and just so you guys know i did disable c1e c3 and c6 steppings to keep my clock at 4.8ghz constant. I have an Asrock Extreme3Gen3 Mobo. Also When i run battlefield 3 it doesn't downclock only when i use prime 95, its really been bothering me so if anyone has had the same problem please let me know. Alright well thanks for the help

What are your temps? Perhaps thermal throttling?

um i haven't been stressing for that long but it seems to be in the 50s-60's it doesn't get too hot. It almost instantly clocks down to the 3.9ghz 4ghz range. I'll go disable thermal throttling in the bios and get back to you.

disable speed step/turbo boost. set thermal power limit to 250. don't modify any of the C power states. use offset voltage for the CPU instead of fixed if your motherboard supports both.

Make those changes to stop the clock from down clocking. It needs sufficient power.
Has nothing to do with thermal.

Problem still persists, i tried it with and without the c steppings enabled. When disabled it seemed to go down from 4.8ghz to 4.4ghz minimum. When enabled it was right around the 4ghz margin. Also I had the C steppings disabled so my processor would run at a constant 4.8ghz..

Might be a long shot, but has it got anything to do with the version of prime your running?
