    These monitoring programs are constantly polling the system, so you will get different things happening sometimes when they are running. For example a lot of people with sound cards get DPC spikes with certain software.

    I usually use HWINFO and Real Temp for monitoring when I do any stress testing/benching.

    Conners,

    Yeah, I almost did that and I would have wasted 4 or 5+ hours and ended up in the same place. It was CPUZ that was causing the "problem" with IBT performance. I'll wait for W8 for the fresh install. The 3770K running at 4.2GHz appears to be about as fast as my 2600K running at 4.5GHz.

    Now that I am an "Offset"/"DVID" convert I have another question on the way ASUS (P8-Z68-V Pro BIOS 3402) and Gigabyte (GA-Z77X-UD5H BIOS F14) implement OC'ing. My ASUS system (2600K) is running at 4.5GHz and all the settings are Auto. A bit more Vcore and heat than if I did it myself but acceptable. It appears that in order to get the Gigabyte (3770K) system to run much beyond 4.2GHz I have to start playing with the LLC, Vcore and DVID settings? Does ASUS do it "better" for dummies by handling the Vcore based on clock speed?

    I had to prove to myself why all of a sudden CPU-Z was the culprit. I ran IBT on the 3770K GHz system @ 4.2GHz for 10 passes with CPU-Z 1.61.5 running in the background - time 174.72 seconds to complete. I reran IBT with CPU-Z 1.61.3 running in the background - time to 155.83 seconds to complete. Task Manager says CPU-Z 1.61.5 uses ~3% of the cpu and CPU-Z 1.61.3 uses ~0% of the cpu!
