Phenom II X4 965 core calculation speed.

acperience7 · Jun 13, 2010

Hello, I was running Prime95 to check my core and MB temps and noticed that core 3 had completed 1 more work thread than the other cores. I also noticed that core 1 was just slightly behind the others. Is this normal?

I was under the impression that since it's all calculation and all cores are doing the same calculations that they should be performing the same.

I may just be paranoid, but this is my first build and since it's pretty much new (May 12th) I guess I'm a bit nervous :ohwell:

.

Thanks for any help.

If it's at stock, my only guess would be RAM.

Mine does the same thing oc'd? With mine it's core1 that laggs behind ALOT i brought the same issue up in another thread because i didn't know wether to rma or not

I have had this issue with my Q6600 and my current Q9650 I see this not as an issue more as a lag from the program .

Even though prime is running, the OS still needs some CPU time occasionally, hence the difference in number of iterations completed.

It's always been that way.

I don't see any problems with your CPU or Prime95 it always been like that even on dual core some core will finish before others...

There is no way that the 4 cores will be use all at the same level or at 100% all the time
Remember that we still DON'T have good programing/coded softwares that will take FULL advantage of multi-core CPU's , probably not even dual-core

It is mostly Windows that takes "care" of it & some softwares will go for the less busy core at the moment of use so i wouldn't worry about it , it is the way it is now until we get real programing/coded softwares for multi-core use...

Anyhow do you have the latest version of Prime95 64bit?
