Intel Extreme Tuning Utility issue

[themyst]

Hey guys, put together my 4770k the other day, and I was trying to utilize the subject application for overclocking, but I'm running into a peculiar issue where the CPU does not utilize at 100% when benchmarking.

It will go from 97% to 50, to 99 to 46, in an oscillating pattern, which I'm sure is hindering results or the ability to use it in any meaningful way. It happens both stock and with increased multiplier.

I'm not sure if maybe the utility doesn't play nice with my motherboard? It's an ASrock Z87 Extreme4.

I'll post a screen shot of the issue when I get home.

hi, here is a screen shot of the oscillation. There is no CPU throttling evident.

you have to have chipset drivers and Intel Management Engine installed
I'd recommend against using it..
Use the AsRock lightweight utility if you must OC in OS..
but you really could do it in BIOS..

I happen to like the Intel utility. Make sure you're stressing all 8 threads.

How do I stress all 8 threads in the Intel utility?

This happens at 100% default settings in the BIOS as well. I don't understand why. Even my Passmark CPU scores are bad.

Interesting.

Try Prime95 with "Number of torture test threads" set to 8 and see if it does the same thing.

EDIT: I just ran the benchmark in IETU and it was the same - not a consistent 100% load. I suspect that's the nature of the test.

See below. Ran Prime95, baked all cores consistently and frequency did not vary at any point in the 6-7 minute test, no errors. This is at 4400, 1.25v, air cooled. This CPU even posts and sometimes gets into Windows at 4.6 1.25v which is the Acer "method" of determining a good Haswell.

I guess it's a decent chip for clocking at least.

It's just the way XTU works, mine always does that to but if you use prime95 or other BM it should be fine .

XTU works good but you maybe limited on settings available , but it seems very stable and solid .
