Starting with stock clocks and everything at auto with the exception of XMP enabled, we first attempted to literally crank it to “11” via MSI’s game boost. We did notice right out of the gate that the MSI supplied CPU-z (as well as our own non-branded version) does NOT accurately read CPU Core voltage, so disregard that number through this testing period.
One reboot later, and we are humming along at a nice 5.4Ghz! That’s pretty darn impressive for an auto-overclock. Next we use MSI’s Command Center to push it a bit further.
Well, 5.5Ghz is really something. BIOS reports 1.450V Core voltage at this clock. We could cruise around windows, surf the web and do any light weight stuff we wanted, but a few seconds into a benchmark we would get a BSOD so it’s not stable. Still, bootable and lightweight tasks running at 5.5Ghz is something you don’t often see!
Jumping back to the BIOS to take over by hand since the MSI Game Boost functions the same via the knob on the board or the software mode from the Command Center, we tried to find the best stable clock we could run daily.
In the end, we settled on 5.33Ghz at 1.42V. This was fully stable in all benchmarks and stability tests like OCCT, and yielded hot, but not quite to the throttle point temps of mid-80’s (Celsius) under full load. This is uncomfortably hot for most enthusiasts, but well within safe limits per Intel and only under peak loads. Gaming and most other similar day to day tasks yielded upper 60’s to mid 70’s at these settings. For Cinebench R15, this yielded an impressive jump from 970 to a whopping 1140, roughly at 18% increase. With more time, I can see 5.4Ghz being daily stable with some more refined tweaking, but this far over 5Ghz, I’m not sure a few tens of Megahertz matter much anyway.
