should be 16x for sure top slot

Thanks man, i ask cause on photos, the VGA was on the 1st one, and CPUz show 8X.

Thanks for all this great info !!! and send my BR to your little boy!

Would copper foil tape, with conductive adhesive, also be acceptable? Every silver pen I find is rated poorly. 

Yeah works now thanks, only minus at the moment is the limited multiplier to boot with from bios.

 

WTB better cpu :( .

But I can see why splave is only interested in bothering with the Micro ATX version though... because as an overclocker, the 2 dimm slots is much better. Wheras the regular ATX board was known to be somewhat problematic in regards to the memory.

Still, I don't happen to own the M-ATX version. Just the full atx myself. No idea where else / proper channels to ask about this since it is an unofficial mod BIOS. Will be getting a hardware flasher soon. :)

Good sharing Splave!

7.51D BIOS can also work with Kaby Lake ?or I need to flash 7.41D BIOS to do so?

Regards

Could you run some benches to verify the performance is there? I've seen some people on reddit who have modded bios to get cfl working and it even seems they can OC according to cpuz, however they score like stock.

Thanks Nick! Outstanding stuff. We are very grateful. I will also let my friend know online, who has same board. We were planning to make a mod BIOS ourselves but you saved us the work. BTW (and this is important) there have also been found a number of boards which did not change very much from Z270 to Z370. The design is much the same, including the VRMs and layout etc. These boards have been backwards flashed with Z370 BIOS succesfully. This then lets support FULL overclocking features and controls for hex core.

Since we noticed that you may have skipped / passed on updating super carrier / i7 professional / oc formula in z370. The any Z390 board with similar IR35201 and other design is going to be helpful as a backwards flash candidate. This may not be possible for such board as Z170 OCF here. But there is still others like Z270 supercarrier and it seems IR35201 is still used. Of course you may need  to change board design in future successor products for many other reasons and purpose. So not to worry about Just wanted to say / mention.. :)
