Now I'm taking my first crack at overclocking and want some input on my voltages and temps. I found some good guides and have been using Prime95 to test for stability. I'm playing it safe at 4.4 GHz for now, and want to make sure I don't do anything to compromise the CPU lifespan. I'm running with a fixed voltage input and LLC level 1. All tweaks were done through BIOS.
After some initial tweaking, I found that I was Prime95 stable for a 16-hour test at 1.220V, but then crashed a couple of times while idle because the voltage dropped to 1.200V. I then ramped up the fixed voltage to 1.235V, which upped my idle voltage to 1.215V. Hoping that helps the problem, but we'll see.
One more thing: I noticed that my CPU speed drops as low as 4.0 MHz while Prime95 is running. Any idea why it's not consistent?
Anyway, here are the CoreTemp and CPU-Z readings toward the end of my 12-hour test from last night:
And here's the AXTU with the relevant voltages:
Could use synopsis from a more trained eye. Any suggestions are welcome. Thanks.
You have quite a bit of overclocking headroom left.
Intel's max recommended voltage is 1.52 volts, although a lot of us feel 1.40 - 1.45 volts is a safer limit. And 70 C is a safe upper limit for load temps. That is if you want to see how far you can safely push.
On the other hand, there's certainly nothing wrong with 4.4 GHz.
