I'm really trying to get a stable 4.4Ghz out of my CPU, but I'm having a heck of a time. I'm pretty sure I am the problem because even thought the 860k isn't known to be a world class overclocker, 4.4Ghz SHOULD be achievable. I haven't even come CLOSE to uncomfortable heat levels.
Here's where I'm at. I can get 4.3Ghz without batting an eye. Prime95 temps sit in the mid to high 50s after several hours. That's without touching anything other than the multiplier setting.
When I try to bump that last 100Mhz is where I hit my knowledge wall. As soon as I set the CPU voltage to manual to raise the voltage, strange things happen. If I lower the volts, it becomes unstable as one would expect, but if I raise the volts, two things happen. First thing is the volts displayed in OHWmonitor are higher than I set them, ie, I set them to 1.5 and they reach as high as 1.55+. Scary. The second thing that happens is the CPU throttles even though the temps are barely in the 50s. When I display all the temps in openhardwaremonitor, none of them look any more unusual than normal.
So, I am making the assumption that 4.4Ghz is within my grasp because my temps are so low, but I have to be missing a setting I need or I'm setting something incorrectly.
I would think the VRM's might be limiting things, but I have one of the best FM2 boards available besides the crazy expensive Crossblade Ranger which has the same 8 phase power with exceptional cooling that mine has.
I know it's in there. I just need help finding it. Ideas?
Here are the bits I'm working with.
CPU AMD Athlon X4 860k
MOBO Asus A88X Pro
RAM Crusial Ballistix Sport 1600Mhz 8Gb 2x4Gb
PSU Sentey 850w 80+ bronze
Case CM HAF XB Evo
2x140mm front fans, 1x120mm rear exhaust, 1x120mm on the Freezer Xtreme Rev. 2 cooler, 1x200mm ceiling fan.
