Looking for assistance with boosting an i7 920's performance?
Looking for assistance with boosting an i7 920's performance?
I have an asus pt6 deluxe motherboard with an i7 920 cpu running at 2.66 ghz and I wanted to overclock it to around 3.4.
I attempted adjusting the base clock from 133 to 160 but faced stability problems. Are there additional BIOS settings I should modify besides just the base clock?
I have 16 gigs of ddr3 ram, a gtx 960 4 gig, and a stock cooler.
Sorry for the delayed reply. Your RAM is configured at 1333 according to the XMP profile. The only adjustments made were to the CPU voltage and QPI/DRAM voltage, both fixed at 1.35 volts. I manually adjusted the RAM voltage to 1.65v, which matches what your RAM kit requires.
My BCLK is set to 190Mhz. Keep in mind that increasing this speed affects other system parameters like RAM, uncore, and QPI. Raising BCLK necessitates adjusting memory speed to maintain stability near the original 1333 setting. For memory speeds you choose, set your uncore accordingly—such as 2666 for a 2666 MHz memory. Be aware that the default QPI speed is 6400 MT, though this can vary depending on your BCLK configuration.
I wouldn't suggest high OC levels with stock cooler. Have you checked the OC sticky threads for some prior context on OC before beginning? Regarding your setup, what voltage are you using for Vcore and QPI/DRAM? I have the same motherboard with a 980X. Previously, this board had an i7 920 running at 3.8Ghz.
BIOS would be ideal. Also, what is your RAM configured for? For the 920, your uncore should match twice the RAM speed, and QPI must exceed the uncore.
I'll capture a photo of my bios upon returning. Appreciate your assistance.

My BCLK was configured at 190Mhz. Keep in mind that increasing this will raise other system speeds, including RAM, uncore, and QPI. Raising BCLK means you should increase memory speed accordingly to bring everything back near 1333. Adjust your memory speed if needed, and manually set your uncore to twice the manual value—for example, 2666 if using 1333. Be aware that the default QPI speed is 6400 MT, though this can vary depending on BCLK settings. I recommend setting both UCLK and QPI link rates manually. I believe I left all other parameters on auto. This was a relatively straightforward overclock if I remember correctly for this board and CPU. If you aim higher, that might be different.
Feel free to ask if you need further clarification.
