Overclocking Results

 

CPU Overclocking

 

I have decided to reduce the CPU VCore to 1.4v applied (I will measure real VCore at the output capacitors), and see how high I can validate. On most boards it's 5.0. I have also decided to add real voltage levels compared to what is set for all motherboards, if they don't have voltage read points I will mark where I read the voltage.

The C7Z170-OCE overclocks better than the C7Z170-SQ because of the LLC and ability to disable idle voltage drop.

On the C7Z170-OCE, I was able to run 4.8GHz with XMP and 4.1GHz cache. The motherboard worked quite well, and if you leave all the c-states enabled and use override voltage mode, it actually will drop the voltage at idle (like adaptive mode).

I have measured VCore LLC on the board at 1.3v, beware that LLC "Enable" means that Supermicro's tweaked standard Intel specification with a droop is enabled, but disabling LLC forced an override and increased the voltage under load. Sometimes that increase is very high, so please use this table. I didn't mind using the LLC enabled since the voltage drop isn't that low, only about 30mv.

 

Memory Overclocking

 

Test 1: 4x8GB (16GB) Corsair Vengeance LPX 2666Mhz C16

This kit worked flawlessly in two DIMM and four DIMM configurations. I am waiting on a BIOS update for higher speed kits, and when I get it, I will update the review.
