I always found that odd.
That is really weird....

Mine's at 1.106 idle, and 1.406 load. When I first start up Prime95, it would show 4789mhz, then after about 30min, it would drop and stabalize at 4679mhz.

Set to 4.8ghz in bios.

I have the power saving options on but it shouldn't mess with voltage really.

Mines not a true 4.8 ether bclk is default around 98.8 or something so you get a little under. I would set it so it's normal but i would probably need more voltage and I'm not pushing my luck.

Well my bclk's at 100 even so I don't see why my OC would start at less than what I set, and then drop a little.

Whats the BCLK when you first start and what's it at when the speed drops?

Try disabling spread spectrum if it isn't already.

I set the bclk to 100 in UEFI. How can you tell w/o restarting PC and go into UEFI? I'll have to try to find the speed spectrum option later tonight.

CPU-Z will tell you what it's running at.

Okay. Went home and tweaked around. Set multi to 47 manually and disabled spread spectrum and now running prime for stability testing.

I'm seeing the multiplier change during prime testing. Vcore is maxed at 1.336v and the multi is changing from 44-47. hmmm...

Which multiplier are you changing in the bios? Sounds like turbo is kicking in. Manually set all your turbo multipliers to 47 as well. That will not allow turbo to down clock when all 4 cores are in use.
