Gigabyte X58A-UD3R/ I7-930 need Overclocking Help

**Talaketu2** · 27-10-2010

I have X58a-UD3R with i7 processor from Gigabyte.I can clock upto 3.86GHz by referring to some guide on Internet. But I want to overclock to 4.0GHz. If any one can provide any suggestion to do this I would appreciate it. I am also having a Noctua CPU cooler. The settings which are stable 3.8Ghz is given below:
Advanced CPU Features:
CPU Clock Ratio : 19

I think your settings are fine.I would suggest you to just change this settings:
CPU Clock Ratio : [19 ] 21x
Intel(R) Turbo Boost Tech: enable
CPU Vcore : start with 1.3250v
QPI/VTT Voltage 1.150v :start with 1.35000v
Test it with this setting and if not get stable then try by raising CPU and qpi/vtt and Retest. keep on raising until get stable but do not go above 1.4v. Try and stay between 1.3 to 1.390000v for each.

When you set CR to 1T then there would be slight increase in performance rather then decrease.And RAM timings will be faster just lower the number apart from frequency. sometimes you may need to alter the RAM timings as RAM subsytem on i5/i7 is interdependent with the CPU. Sometime you might need to tune setting such as Round trip Latency or increase trfc. If your RAM is running at below rated speed then SPD timings would work in 95 cases.

If you are not using multithreaded program too much and if you are using your system to play mostly games then if you disable Hyper Threading then this may also help you to reach to higher overclock, try reduce heat and power consumption but this can decrease performance in games.Hope this would help to get max overclock.
