Overclocking a Core i7-920
Overclocking a Core i7-920
Hello All,
I'm seeking some advice on how to overclock my system. I'm currently running stock and aim for either 3.5 or 4.0. I'm using a Core i7-920 on a Gigabyte UD3r v2 motherboard. Any suggestions would be appreciated, as I've never done overclocking before but feel confident in the BIOS. Also, keep in mind I'll be adding a Corsair H90 140mm liquid cooling system soon, so temperature shouldn't be a concern.
Have you gone through all the manuals and grasped the potential dangers? When I first used my i7 920, it was straightforward with just a few guidelines to follow. Your Uncore speed should match twice your memory speed, and your QPI multiplier must exceed your Uncore. I recall setting it at 3.8 Ghz with minor tweaks. I adjusted the Vcore and QPI voltage to 1.35v, configured RAM at 1.65 as per my system’s specifications (likely XMP timings), changed the BCLK from the default 133 to 190, and locked the CPU multiplier at a maximum of 20—though I suspect you could reduce it further. For RAM, I maintained the 2:8 ratio to achieve a frequency of 1520 MHz (190 divided by 2 multiplied by 8). Concerning Uncore, I used a multiplier of 16 and QPI of 18 for a DDR speed around 6.84GT/s. These were probably the main aspects of my setup.

These were the main configurations I applied, though it has been quite some time since this setup was active. At that time, I had a large air cooler installed. I disabled speedstep and C-states, keeping the frequency steady at 3.8Ghz under load. I continued running the 920 for about two years before selling it, and it’s still functioning properly today at stock speeds.
