I think I broke my computer (GA-X79S-UP5, i7 3930k)

post #1 of 4
Thread Starter 
Overclocked to 4.37, it was a little unstable and the temps were a little too hot (80+ on water cooling), so I dropped it back to 4.25. Still didn't feel very stable, so I reset everything to optimized defaults and rebooted. I have a feeling that this is when things went awry, but I didn't notice all day while working.

This evening, I reboot and decide to pump it back up to 4.37 for some rendering in After Effects. I also adjusted the dynamic vCore to +.005. During boot, system tells me that this config won't work with my hardware. I boot to BIOS and set it to optimized defaults instead.

Reboot, BIOS looks good 3.2 GHz on the chip.

Reboot, to MacOS, but then the system only reads 1.5 GHz on the processor. Reboot again to optimized defaults and now the system reads 1.2 GHz. Geekbench and the BIOS think it's running at 3.2 (the default for the chip, I guess), but system performance (sluggish at best), temps while rendering (50+ in stead of 70+), About this Mac (1.2 GHz), and geekbench scores (6.5k) all lead me to believe that the processor is running at 1.2 GHz.

Any help and/or advice is appreciated.

I did. Same result. HackOS still shows CPU at 1.2 GHz. No throttling up to higher values.

UPDATE:

According to the build post on tonymacx86.com, one of the steps the builder took was to disable EIST. I did and now I'm back to running at stock (3.2 GHz and 1.068 volts). Temps are in the high 50s at load.

Is this seriously all that was wrong? EIST!?!? I could have sworn that that wasn't disabled the first time around.
