My goal is 4.2Ghz but I'll settle with 4Ghz  Can any of you that successfully OC this MoBo w 6800K share your settings with me? I'm tired of trying and still getting freezes all the time -ASRock Fatal1ty X99 Professional Gaming i7 -6800K -H80i Cooler -CORSAIR Vengeance LPX 32GB (2 x 16GB) 288-Pin DDR4 SDRAM DDR4 2800 -SAMSUNG 950 PRO M.2 2280 512GB PCI-Express 3.0 x4 -NVIDIA GeForce GTX 970 THANKS!!!!!

Broadwell-E is not a great over clocking processor, but 3.8 or 4.0 should be a given. Mine does that fine, and beyond, not exactly the same ASRock X99 board, but the differences are minimal and essentially none in the UEFI/BIOS.

First, have you tried setting your memory to 2133, to take it out of the OC equation? With your memory at 2800, using the XMP profile I assume, what is the BCLK set at?

I'd also like to check your memory for compatibility, exact model number please.

You should be able to set the Core Ratio/multipliers to 40/4.0GHz with VCore on Auto, and the BCLK at 100MHz. LLC at level 3 or 2 is plenty.

CPU Input voltage is at what now? What is the VCore you get using the OC presets?

What are you C State settings in Advanced, CPU configuration?

What is the CPU Cache speed set to?

Thanks Parsec!

Moderators Note.

I have consolidated all posts by moving the ones in "Intel Motherboards" to the OP's dupe Topic under "OC Technical Discussion"

I felt that this topic belongs in the OC section.

EDIT: And I just deleted a couple extraneous posts to keep it simple reading.


Carry on.
