Hoping someone can give me some advice or suggestions on manually OC'ing my Z87x-D3H, I5-4670K with 8Gig of Gskill Ram. I followed this guide closely using the two profiles listed on Page 1 as follows:
- Profile 1: CPU Freq. of 45, Vcore of 1.30, VRing of 1.15, CPU VRIN Overide of 1.8, CPU VRIN Loadline Calibration of Extreme and disabled C1E, C3, C6/C7.
- Profile 2: CPU Freq. of 44, Vcore of 1.29, VRing of 1.2, CPU VRIN Overide of 1.7, CPU VRIN Loadline Calibration of Extreme and disabled C1E, C3, C6/C7.
For both both of the above, I also had XMP turned on for my memory to Profile 1, which correctly matched my Mem of 9 9 9 24. I didn't change the Uncore or other items listed in the more advanced section.
However, at either of these settings my CPU would not even boot into Windows and would sometimes get hung up in the Bios load screen until I would do a cold boot. Disabling XMP did not help. I then tried the Auto Performance Upgrade of 40 and 80%. The 80% mode also failed to boot into windows but happily at 40% and XMP enabled to Profile 1 I could load windows. Ran Prim95 torture test for over an hour with no errors. Also did the 3DMark and PC Mark benchmarks and got about a 10% to 5% boost respectively in performance from stock (included OC'ing my GPU, which I only did after I got the successful system OC).
However, I feel I could still get more out of this. Going by my CPU Status in BIOS, this auto mode has me running at a CPU Core Ratio of 44 (not bad) but with high CPU Vcore of 1.404 and a CPU VRIN of 1.75. My CPU temp at idle in BIOS is 34. So... I was wondering if my problem with my manual OverClock was using a voltage too low for my system. Would one think that I could go back and manually set it to 45 or 46 with voltages somewhere between those listed in Profile 1/2 and those set by the auto OC?
Thanks for any advice.
