Lower OC capability on M6F compared to GD65?

[kangk81]

I was previously using MSI's Z87-GD65. The reason I switched to the M6F is because no one makes VRM blocks for MSI or I didn't look hard enough.

But now I have switched, I'm finding that the M6F is only able to achieve 42x stable @ 1.333VID whereas previously I was able to achieve 45x stable @ 1.35VID on the GD65 on the same 4770k. While at 46x the GD65 BSOD the moment I boot to Windows, the M6F is able to at least hold for 1 cycle of Realbench 2.1 bench test. The is the part that it's weird.

Vin for both boards is set at 1.8V, LLC @ Lvl 8, voltages in override mode, cache clock in auto 39x, RAM in XMP 1600MHz 10-10-10-27.

I have also experienced random reboots with no failure while playing Bioshock 3. It's hardly a game with hardcore graphics given I'm running 2 GTX770 in SLI on stock clocks. It even reboots occasionally in Uniengine Valley.

I'm gonna try Crysis 3 and see how it goes. Meanwhile any help is greatly appreciated.

doesn't the thread title say that the maximums is the poor overclocker

But in you post you say the GD65

??

Hmm whatever the merits of either board...such a big difference is not going to be explained by the brand or how each board can perform. Must be failings in the particular board rather than the model if that is the case or differences in the way you have OCd on the last compared to this one...or some info missing maybe...

have you tried to transfer OS from one to another? Or done a clean install of OS on the new board?

I've not tried a clean OS install. this is my 3rd z87 board in 6 months. The previous 2 were not up to my expectations for 1 reason or another.

I have too many work files store in this hard disk. Maybe I should clean install when I have the time.

If you are transferring the OS between the different builds I would do a fresh install yes....at least reinstall the main drivers... Chipset driver (MEI driver too?)...LAN...graphics

Read up on the board and how to OC it http://rog.asus.com/forum/showthread.php?33488-Maximus-VI-Series-UEFI-Guide-for-Overclocking&country...

Things change between boards

Yup I installed the new driver and the Intel ME drivers..

Shortly after my last post, I went back to the drawing board and reverted to basic troubleshooting.... changing 1 variable at a time.

I did a CLR CMOS and set it to 45x and 1.4Vid and let it run F@H(I do folding 24/7) then reduce Vid by 0.01V 1 hr at a time. Now I'm @ 1.35Vid and everything has been stable so far.

I only changed the core mux and Vid and left everything to auto...maybe the rest of the voltage tweaks is causing the VRMs to be unstable given my less-than-average 4770k

OK understood...looks more promising...just keep experimenting....I guess the tweaking is half the fun..:)
