So I was running prime 95 v25.8 build 4 for a few hours, and i realized core 0 was going faster than core 1... it was at a higher test number, although just a few.

Should i be concerned about this? Anyone know why it does this?

it was an e8400 @ 3.6ghz [1.2v w/ vdroop] on win7 x64 if that helps at all

It's fairly normal unless it is MUCH faster. Remember that Windows processes will suck some CPU cycles as will any background tasks.

Core 0 is the actual core thread, while core 1 uses hyperthreading. Hyperthreading makes use of what the actual core isn't using, so the hyperthreaded core will not have as much power at its disposal.

Post that in a thread where the OP is using Hyperthreading.
