I am a little new to overclocking and just need some help. I have my I5 2500k oc to 4.6 but when is use intel burn test/ prime 95 after 5 out of 10 runs (I know I am not testing very long but I get worried) my multiplier goes for 46, to 33 (and 16 between tests and i know this is normal). the same thing happens by test 13 (~ 10mins) into prime 95.
Again I know I should run prime 95 for like 10-24 hours but I am worried when I see my multiplier moving like that (46 to 33 to 16). Is this normal or not? I am running on a asrock z68 pro3 gen3, so i can't change my vcore itself (I can change the offset up or down) any help on this would be nice.
did an intel burn test (stranded 10 runs ~ 2 mins) lasted 7 runs with out dropping from x46 (cvolt 1.344) then dropped to x33 and Norton poped a warning about "high cpu usage". temp maxed at core#0 64 core#1 73 core#2 73 core#3 71 and package 76. Could Norton be causing the multiplier to drop back and forth?
76degC is Wayyyyyyyyyyy tooo hot! The temp is certainly what caused it to lower.
Personally 65degC is max.
Leave it clocked @ 4.4 until you get an after market cool on that bad boy, may I please suggest the very cheap, but outstandingly good Coolermaster 212 Evo, it can be picked up for as little as 25-40 dollars!
Ok thanks, I thought good temps were 70. I do actual have that cooler on it already (with a fan on each side). Maybe I should try reseating it on the cpu. but I will restart over clocking with 65 being the max I go for.
A 2500K shouldn't throttle until ~98C. I've had my 2500K up to 93C when stress testing with a OC on the stock cooler (pure stupidity, lol), and it didn't throttle, so temps aren't your problem, even if they're a bit high. 76C is above the recommended max, but just by 4C, so it's not devastating.
And 70C is OK (72C recommended max).
Don't really know what the problem is here, honestly.
i have downclocked to 3.8-3.9, 3.8 didnt dip after 15 min on prime 95. so I uped to 3.9 and left is sit and did some house work. and after 30mins came back and it was starting to dip to 3.3 again. temp was 63 max. I may have to look at bios more and see if i am missing something. still think I am going to re seat my cooler tonight.
I guess at the same time this only seams to happen on stress tests and not so much on games (hard to always tell tho). Would it be a good or bad idea to forget the stress test and just go for game stable ( temp stable)?

I supposes that's a band-aid for it, but you need to see if it's happening during gaming too. It's not really a great idea to completely abandon stress testing since you won't have a way of testing stability on the OC's, other than gaming.
This is a software issue of some kind I think, but I just can't think of what. Norton shouldn't cause it, I wouldn't think. I suppose that it's possible that it's a BIOS issue, but it would be a strange obscure one, if it is. This is already an obscure problem anyway, though, lol.
The only thing I'm SURE of is that it's not a temp throttling issue (not with temps in the 70's).
