I've been here for a while and have tried to learn OCing. Could you confirm if I have a suitable setup for 3.8GHz? I ran Prime95 (self-test "blend") for six hours using the settings listed, and everything worked fine with no issues. My core temperatures during peak usage were between 71-70-68-66, averaging around 70-68-67-65 as measured by OCCT on the monitor. In idle mode, they stayed at about 41.
My configuration details:
- AI Overclock Tuner: XMP
- Profile Info: 1600MHz-8-8-8-24-2N-1.65V-1.35V
- CPU Ratio: Auto
- Speed Step: Disabled
- BLCK Frequency: 190
- PCIe Frequency: 100
- DRAM Frequency: DDR3-1523MHz
- UCLK Frequency: Auto
- QPI Line Data Rate: Auto
- CPU Voltage: 1.225V
- CPU PLL Voltage: Auto
- QPI/DRAM Core: 1.26875V
- All others AUTO except:
- DRAM Bus Voltage: 1.65V
- Line Load Calibration: Enabled
- PCIE Spread Spectrum: Disabled
Please let me know if this setup meets expectations or if further adjustments are needed. Thank you.
It looks great! Seems like you've mastered the basics so far. I'd suggest running prime 95 with small ffts just to verify stability. You've got a solid chip here. I think pushing it a bit further would be wise.
Overshocked: Looks great man! It seems you've mastered the process so far. I'd suggest running Prime95 with small fft's (rounded) for about two hours just to verify stability. You definitely have a solid chip here. I think pushing it a bit further would be wise. Submit your overclock details to this new thread, thanks: I decided to run Prime95 using the small fft's (rounded) for approximately two hours without any issues. Temperatures stayed consistent compared to those using the "blend" test. However, my "auto" CPU ratio setting has shifted from 20 to 21, which means my clock is now exactly at 4.0. Should I be worried about running this at such low voltages (1.225 and 1.26875)? Wouldn't a higher clock speed require more power to operate safely? Thanks again!
Running at a faster pace and lower voltage won't cause any issues. It's safe as long as the system remains stable.
I was testing my i7 920 at 2.66GHz with a voltage of 1v, which was the default in desktop mode. This setup worked well with Prime95 for extended periods. But as another user pointed out, reducing the voltage caused more current to rise, leaving power usage unchanged. Eventually, I raised the voltage to about 1.1v and discovered an optimal balance for minimal idle power at roughly 35 watts (versus 42w at 1v, ~45w at 1.2v, and ~38w with stock settings).

Chuck, with the same motherboard and processor (DO stepping), your settings are working well. Trying to push the CPU to 4.0 by increasing the block reeq to 200 and voltage to 1.25, how much more would you need to boost the QPU/dram core?
