Ach! i5-2500k core 4 @ 100% during gaming, all other cores @ 30%

post #1 of 10
Thread Starter 
For some reason, whenever I play BFBC2 though Steam (non-steam version) core #4 on my I5-2500k maxes out at like 94%-100% meanwhile cores 1-3 are only at like 30% or so.

My overall temps are only hitting maybe 58C give or take 2C. (I also am usually running Chrome or some web browser in the background) I have 8GB's of ram, so I figure why bother to close all my tabs? biggrin.gif I haven't noticed core #4 acting strange during anything else like Photoshop, Sony Vegas, etc.

Although that shouldn't affect it so much. I even closed all other programs besides Steam and the game, and same results. I've had this CPU since July of this year.

Nope, same result. frown.gif

I tried COD: World at War too but it doesn't seem have have any bias towards CPU #4. I also tried Crysis: Warhead, and everything seems fine there too; maybe favoring core #3 a little, but only by like 8-12% more.

Well if I were in my dorm I'd check its usage... we'll see if others chime in.

EDIT:
Run prime95 and see if it has any errors. It'll use all your cores for sure. If it doesn't or errors out.. it may be your oc.

I just thought it was strange. I mean, is this anything to be concerned about? I had a 12-hour Prime95 run with no errors when I did this overclock (4.4GHz), and I literally haven't touched the BIOS since. This was maybe... almost two months ago now since I did the overclock?

With Real Temp 3.67, Core #4 doesn't seem to be running unusually hotter than the other cores... maybe like 7-10C hotter than the coolest core, which is normal.

OK... funny thing I noticed. Only core #4 is running at 98% during the BFBC2 home screen meanwhile cores 1-3 are at like 3%... but once I load up a match they even out way more. with cores 1-3 at like 50-70% while core #4 is still slightly higher usage at like 80-93%.

BC2 puts everything on the last core then overflows it to the others. My E8400 did it, my 2500k Does it, my friends Phenom X3 does it.

Perfectly normal in BC2.

Oh it's good to know that this isn't an isolated case, it puts my mind at ease. +Rep!

That is also how my 2500k@4.5Ghz behaves when playing BC2, core 4 is close to 100% with the rest hovering at 20-30%. BF3 beta was using all cores properly but still not maxing them out at 100%, GPU limits kick in way before the SB maxes out .
