Re: Asrock Z68 Pro 3 Overclock Help
Z68 Pro3-M, i2600K, Corsair H60 cooler Gskill 1600 7-8-7-24 runing stable a 44 multiplier with a manual voltage offset of .040. Temps hover in the 65C range on Blended Prime test.
Initially I could not get it over 42 no mater what but after I replaced my Kingston hyperX Ram with the GSkill I was able to get over the hump. I first bumped the multiplier to 43 and ran Prime for a couple of hours. Than I just bumped it again to 44 with no changes to voltages (all AUTO) but got a crash after 14 min. I started tweaking the voltage offset and got much better results. Still testing and tweaking but:
What I currently have as stable configs are
44X with a manual voltage offset of 0.040
45X with a manual volatge offset of 0.050 - only tested for 1 hr
Now to my question/oddity
While runing Prime test I was looking at CPUID for applied voltage and multiplier. I noticed that whe runing with the 44X multiplier the processor was actually jumping between 41 and 44 but staying at 44 most of the time.
When runing Prime test with the 45X setting the processor was jumping between 39 and 45 (wider range) and staying at 45 only about 20% of the time. Just for grins I ran a video encoding test using Handbreak and indeed the setting at 44 finished quicker then the setting at 45. What's up with that?
