2500k gaming question

post #1 of 19
Thread Starter 
Hey guys.. I recently overclocked my new 2500k to 4.8 ghz using the turbo boost multiplier. I've noticed that under CPU-Z it shows that its running 1.6ghz while playing some games and it will occasionally jump to 4.8.. I thought that when my computer wasn't idle it would run at 4.8.. is it normal to see my clock speeds changing during games although it works fine when im stress testing with prime?

Run prime and see if it's still 1.6. Chances are, since you alt tabbed outside the game, the CPU clocked down. Either that, or your GPU is severely gimping your performance.

Yes, but this is fine if it's stable. I've managed to keep speedstep on with my 2500k and it saves ~30W at idle... can't complain there.

I also think it's simply downclocking when you alt-tab out of the game. If you are concerned, I would recommend a graph of your CPU clock so that you can check the history after gaming... (someone else chime in with a program that'll do this? I've got a mind blank)

I don't understand this mentality. You'd continuously waste 25W (or more) and dump that heat into the room just to see ___ghz? If it's stable with speedstep on, use it.

I run a dual monitor so i had cpuz running on my secondary monitor so i dont think the alt tab thing affected my speed.
@ joemaniaci I've tried with both speedstep on and off doesnt seem to change anything. it still runs at 1.6 idle and 4.8 underload with prime.. but in SC2 particularly it still runs at 1.6 and jumps up sometimes to 4.8

somewhat since he wants 4.8ghz 24/7 if you put in power saver/balance it down clocks it. Right now I'm on power saver and just running at 800mhz x4
