I've got an i5 2500K in my MSI Z68A-GD65 (G3).
It was sat at stock for a while waiting for me to get around to OC it.
Then after a while I thought I'd use the OC Genie settings.
Then today I created a new profile based on the OC Genie setting and managed to get it running at 4.4GHz @ 1.35v and complete 10 runs of IBT set to Maximum. Temps were pretty good at around 61ºC across the cores.
While I was in the BIOS I noticed the DRAM voltage setting I had brought over from the OC Genie overclock was set to 1.666v. I thought this was pretty high considering the RAM was running at 1600MHz using the X.M.P. profile. So I set the RAM voltage back to Auto.
I think I also set the VCore voltage from 1.35 to Auto so I could see if it might run lower (I know I should've manually experimented...). Then I saved changes and rebooted.
It was at this point the problems began.
The PC hung while starting up. I think it had got past the post screen and was just about to start booting windows but it sat there with a blinking cursor. Since I hadn't increased any overclock I was surprised that Windows wouldn't even boot, so reset and tried again. But it continued to act strangely until I believe it booted from the secondary BIOS. It would boot ok at stock but once I tried overclocking it started playing up again.
I wondered if the BIOS had gotten corrupted so flashed the BIOS again. Also seemed to go ok, but then I restarted it did some sort of Multi BIOS update. When I eventually got into Windows one of the MSI apps told me I wasn't using the first BIOS. So I rebooted and went into the BIOS, but it was showing as the current version. I thought the secondary BIOS would remain at the BIOS version that came with the board, but it sems I've maybe somehow updated that one to be the same version as the primary BIOS.
Now i'm not sure what BIOS I'm running off. It also seems to turn the PC off, then after a few seconds back on again when I tell the PC to restart. It also occasionally does the Multi BIOS update thing again. I thought I'd found the setting to disable this in the BIOS and disabled it, but it keeps getting turned back on.
Now when I go into the BIOS it seems to be random as to whether I get the default looking BIOS or one that seems to have the 4.4GHz overclock settings in. I'm sure I'd cleared the CMOS and flashed the BIOS since setting that OC.
I'm really not sure what's going on now. It seems to be able to boot into Windows at stock settings, but I'm not sure on which BIOS. There have been no more messages to tell me I'm not using the primary BIOS.
I don't want to try overclocking again until I get the random BIOS switching and other behaviour sorted.
Does anyone have any idea what's going on?
