Hey, I Recently purchased a new build and have been playing about with OC'ing the machine.

I firstly enabled XMP, Set the Voltage to 1.2 and boosted the clock speed to 4.5ghz. (100x45)
After I rebooted, the machine would boot up with a black screen which meant i wasn't able to access windows or the BIOS, I removed the battery and reset the BIOS but I think I need some guidance to get this right without screwing up my machine! Why did my machine boot up with a black screen?

I've left the clock speed at its default (Roughly 1.05) and changed the clock speed to 4.2ghz and am running a stress test using AIDA64, however the machine, every now and then is freezing up for less than half a second.. Is this normal because the CPU is at 100% load? Or do I need to up the voltage?

Also, I've left XMP off however Windows task manager is saying im running at 3000MHz but Speccy is saying I'm running at 1066MHz. Could someone explain this a little better to me?

What CPU cooler? your room temperature? your case and fans? if there're still room to maximize your cooling, do that first.
Depend what version you are using now, for me if there's no POST screen, I'd do clear CMOS, after that if you get POST screen, enter BIOS and follow instruction https://www.msi.com/page/biosflash.

It's a failed preset, either your CPU can only work on certain power preset, or your MSI isn't regulate proper power for your CPU. You'll eventually find best stable preset, I used to spend 2 or 3 hours a day to get my 6900K on Gigabyte X99 Gaming 5P stable @ 4.4GHz, I knew my motherboard wasn't meant for OC, is just that going for Xeon was out of question, after googling a bit I discover OCd 6900K could be four times...

So make sure your OC project is worthwhile for your profit.

Best for you is to contact the SPECCY guys, it doesn't matter because initially Broadwell E runs on 2133 and 2400, at the time of Broadwell-E/EP/EX development those two standard were used, later in Q1 2016 Intel release microcode updates to keep their architecture compatibility toward higher DDR4 clock rate initiated by Samsung, your RAM most likely use Samsung or SK Hynix ICs.
