Overclocking Skylake Z170 with MSI: 24/7 Air, Water and Sub-zero Cooling OC Results by Martijn Boonstra

On MSI's Gaming blog we find a nice Skylake Z170 overclocking article posted last week. Martijn Boonstra, product marketing at MSI Europe, took the latest MSI Z170 motherboard for a spin and wrote down his thoughts on overclocking the latest Intel processor architecture. In his article, he compares air, water, and sub-zero cooling results.

The setup he uses consists of the MSI Z170A Gaming M7 motherboard, an Intel Core i7 6700K processor, a set of Corsair Vengeance LPX DDR4 memory, the MSI GeForce GTX780 Gaming graphics card, and it's all run on a Windows 10 Professional installation. The cooling gear used are the Cooler Master Hyper TX3 EVO air cooler, the Corsair Hydro Series H100i all-in-one water cooler, and the LittleDevil Phase Change PC-V2 single stage phase change cooling.

The results are interesting. On air cooling, Martijn achieves a 12% overclock; using the all-in-one this increases to 17%, and using sub-zero cooling we end up with a 26% overclock. There is no information on whether the cpu was delidded and based on the high temperature under load (+15°C), we assume it wasn't. For overclocking, delid is important with Skylake!

Delid is so important with Skylake ... I wonder if that will hurt their sales as I can imagine people backing off from a product that is "overheating" 10-20°C

Funny to see that 6700K is 50% more expensive than 2600K was, and Intel saves on TIM and decided not to solder HS which they did on SB. I binned more than 20 SB CPUs then, out of my pocket, but I see no reason to do the same on skylake at a) this price and b) with the knowledge that I have to take risk of delidding, which can kill cpu, and void warranty on top to get full potential out of CPU. I know lots of people who pay for their hardware think the same, so it will most likely hurt their sales indeed

Belgium Massman says:

That's what we're seeing as well ... adoption of Skylake is very slow. Much slower than Haswell, Ivy Bridge, and Sandy Bridge.

I'm surprised to see that frequency range on SS with Skylake, is that due to voltage limit assumed by testers or the CPUs stop scaling? I was able to reach 5500 benchable with random retail Haswell with 1.65-1.7 vcore.

Belgium Massman says:

It makes sense if you consider that Skylake really needs delid to take off :(

Hi guys, first of all, thanks for appreciating my efforts and sharing them.
As you already guessed, I didn't delid the CPU yet. I am saving this for part II where I will be showing a short tutorial on delidding and conduct the exact same tests after delid to compare temps and voltages. After that I will test to see how much of a speed increase we gain by delidding in the same scenarios, keeping the same temp. limits in mind, with the goal of a solid 24/7 OC. I will do some extra (non 24/7) overclocking on sub-zero as well.

Aha! Now we have a nickname to go with the real world name :D

Might be related to no availability in USA though but not entirely.There is also the memory factor,Sandy Ivy and Haswell all worked on DDR3 so you could get your platform up and running with existing ram then move to a better set later on,while now if you don't have any x99 platform laying around you have to get new ram as well,another expense.

Put that to the mediocre at best Skylake overclocking and there you go.

Asrock has a few ddr3 boards though so thats not really true. 90% sure its US availability theres still a good chunk of interest on OCN and such.

Anyways my temps arent bad predelid. 64c peak in xtu at 4.8ghz 1.41v dmm. 76c peak on wprime
MSI's presets are nice on this board.


One question though what type of hynix are the presets built around? C10 3200 seems tight for MFR

Netherlands t!n0 says:

Are you talking about the regular presets or MemoryTryIt? The regular presets are built around both MFR/AFR presets to run stable. It's just a matter of trial and error with your kit.
