The other day I've been testing my overclock stability(APU A10-7890 4.4GHz) in prime95 custom, out of place, FFT size 768kb and 12Gb RAM.
It's been stable about 4 hours, then I'm coming back and see the bios screen which says something about boot fail and the need to load optimized defaults, because your hardware have been changed. Then I don't do that but just select "go to bios", and see that all my settings are in place and XMP profile says "Profile 1" as always, BUT the frequency says 1333MHz instead of 1866. Again, I only overclocked CPU multiplier, didn't touch memory, NB or GPU.
Then I just have loaded "optimized defaults" and my saved bios profile with all my bios settings. And it's back to 1866Mhz. Ran memetest 13 hours, it's 0 errors.
I guess I need to raise NB voltage or DRAM(it's 1.5V currently, by the way, it says 1.488 in bios for some reason) and retest the overclock. Is this drop in frequency like the built-in protection in modules itself or the mobo? Did somebody encounter this?
