Prime95

I dont know if this is in the right section so im sorry if its wrong

Im running Prime95 for almost 5 hours now and 1 of my cores is playing catch up on the testing its about 2 sometimes 3 tests behind the rest of the cores. Is this normal for this to happen ?

Thanks.

The overclocking and cooling forum would probably have been better, but I'm sure you'll get some answers here.

As far as I'm aware as long as prime isn't reporting any errors everythings ok.

Sounds normal, When I run Prime some of my cores tend to run behind.

Ok thanks guys was beginning to worry a little there.

Remember other things have to run on those cores at the same time, like windows... Primes quite good for picking out memory errors though, as it runs in the background leaving you free to game etc while it's on. Unfortunately it does a rather bad job of heating up the cores these days.

How could you run a game while your CPU is being maxed out?

fairly sure other than actualy setting your cpu on fire nothing else but running all cores at 100% will heat your cpu up as efficiently...

43 degrees under load here

Tbh that's one of the reasons people use prime, you can use your pc while it running in the background. It only maxes the core if no other process is on them and gets shunted down when something else comes along. That's why one of the ops threads is behind the other, windows (or any other program) needed that core so prime got demoted

There are people who put ocs through 24hr of prime blend and future mark (together) and they tend to prove quite stable.

Still, it might say 100% but it's not really pushing them. ITB/linpack max cores fully (try doing anything else while it running

). It's true many people say nothing you day to day will come close to itb temps - which are indeed higher than primes - but then I've found BC2 heats the core up more than prime, only 1/2c short of IBT so really comes down to personal preferences. Different programs for different jobs.
