Supermicro C7Z97-OCE Motherboard Overview and Overclocking Guide

Overclocking Results

 

In this section, I will go through the process of overclocking this board. This board is Supermicro's first attempt at an overclocking centered motherboard, and at the same time, it also carries their first UEFI.

 

CPU Overclocking

 

Max CPU Overclock can be found by setting the VCore to 1.4v, input voltage to 2.0v, cache voltage to 1.2v, CPU multiplier to 45x, memory and cache multipliers to 8x, and disabling any features that would result in CPU frequency fluctuation. After adjusting these settings, I proceed into Windows, and use software to increase the multiplier. In this case, I opted to use Intel's Extreme Tuning Utility, as it's the only software that can OC this board in Windows.

5.0 GHz is the maximum of our CPU on this board, and this is most likely due to the fact we had to use Intel's XTU, and it's not as light weight as other programs from other vendors.

 

Maximum AIDA64 Stable Overclock (BIOS settings below for this):

I was able to easily pull off 4.8GHz on the CPU with 4.2GHz cache, and a 2666MHz overclock on my memory by manually tuning the UEFI.

 

 

BIOS Settings for Overclocking

 

The UEFI lacks the ability to take a screenshot, so I had to take pictures with my camera.

Supermicro provides us with all of the settings we need to overclock; however, they are a bit scattered, and might be a bit confusing. For starters, you have to type in the values you want (make sure to click the "Expert" button at the top of the screen in different menus to show all options), but you must delete the previous values first. BCLK is in a weird format, the default value of 102.00 MHz is "10200," and if you want 100.00, you must delete "10200" with the backspace key, and type in "10000."

Voltages are also there, and are in units of millivolts, so "1300" is 1.3v. The System agent has a default offset of +0.55v to support the 102MHz BCLK. I would personally set 100mhz, and tune down the high SA offset.

The XMP values on my 2800MHz 16GB kit did not work. The board just wasn't able to boot at the 28x multiplier, but it was able to do 2666MHz with ease. One nice trick is that if you select XMP, and then immediately go to manual mode, all the XMP timings are still in place.

You can see the fan profiles above. The second image shows the save and exit menu. The reason I decided to show this is because you need to hit "Save & Exit," then boot into Windows, then shut down all the way, and start up again. If you do not do this, the OC settings will not take. This is because the board doesn't reset after exiting the UEFI, and if you restart unexpectedly from Windows, then all the BIOS settings automatically revert to default.

 

This becomes a hassle to deal with, but you won't ever hang up on POST, or really need to clear the CMOS, because it will just reset the settings for you if you don't boot properly, or if you reset abruptly. This makes the onboard clear CMOS button the same as a reset button (possibly why the board doesn't have a reset button). You can save some basic settings in the OC3 button profile, but not enough for some overclocks.
