Istalled my new I5 2500k....seems fine. running at about 34c, but the clock speed is around 1600mhz. Multiplier at x16. Downloaded CPU-Z and its showing the clock speed at the same....around 1580. Is this an "idle" speed? And if its running at ~35c idle @ 1600mhz, then going to 3300mhz or the advertized stock speed would DOUBLE the temps right??? Please tell me Im not working with a faulty CPU....!!!

Looks like you have speed step enabled which will make that idle speed. It will not double the temp, the fan will speed up as temp rises!

How should I stress the CPU so I can see what kind of temps I get @ higher speeds? Im on the stock cooler so Im not looking to OC yet. Just want to see how warm it gets stock at full load. Any ideas?!

Right on...I have it running now. Clock speed not increasing but the heats up to 45c...guess Ill let it run for a while.

Prime95 stresses your CPU to 100%. I have the i5 2400 at 3.10 Ghz. I installed CPU-Z since your post reminded me its not a bad program to have installed anyway, I already had Prime95 as well, so I fire them both up just now and clock speed reads at 3100 Mhz under the Core #0 section of CPU-Z. And it shouldn't take long at all, it happened for me in like 2 seconds. Check your BIOS settings to make sure the CPU hasn't been underclocked or anything like that. For tests using Prime95, make sure blend is selected. Note though, its normal for it to say like 1598 Mhz on idle under the Core #0 table. However, under specification, your processor should say something along the lines of Core I5 2400k @ 3.10 Ghz. If it says anything lower, most likely its a settings issue in BIOS. Also note after running Prime95, for some reason it wouldn't refresh the Core #0 table, so start Prime95 first, then open CPU-Z and see what it says.
