an z390m ocf is planned ?

not planned no

I tried again last night and you can lower the volts a lot to more like coffee

1.7-1.72vcore seems to be the max of scaling on what ive tried, you can go higher but was less stable for me (1.7 vs 1.72 was almost a full degree colder load)

1.65 CPUPLL can try up to 1.80 there is some scaling (credit to BigBlock)

1.45-1.55 vCCPLL

1.4DMI

1.4VCCIO

1.34VCCSA

2.1CB Killer to help restart at -170ish and can lower to 1.800 in OS not sure it really helps that much

MOCF vrm can handle 9900k no problems. On ln2 no heatsink required, the cold from full pot is enough. However if you are pushing hard on ambient, or even SS then you should use heatsink. Can run without heatsink on air for quick tests fine, but if you benching hard then use heatsink.

EDIT:

Upon further testing from @Splave, its best to use heatsink on vrm at all times, even under full pot ln2

Is updated IGPU vBIOS the same as pcie patching ? "pcie_patcher.cmd biosname"

Just wanting to know if I can run discrete gpu at 16x and not be stuck at 2x

Thank you Nick, Splave and everyone else who made this possible. I have a Z170 OCF. I asked Asrock for a custom BIOS to add Secure Erase as a feature. Would it be possible to add Secure Erase to the custom BIOS? I have the custom BIOS if you need to analyze it. Here are some screenshots:

if it is required when the cpu is at fullpot with ln2 around -180C then i suppose its not a question to use it with aircooling in a pc case, there will be definately not cooler. btw I dont remember any situation when it was recommended to use any board without vrm heatsink when overclocking on air/water. if you dont need to insulate board to handle extreme conditions like condensation, i would never consider removing.

Nevermind, turns out pcie is just fine on MOCF. Problem seems to be my board and pcie_1
Sorry for adding to confusion but pcie patcher is NOT needed on MOCF

Damn. Secure Erase is used to erase SSD before formatting. Do you know how to copy a feature from one BIOS to another?

Just make yourself usb flash drive with HirensBootCD on it, boot into the linux rescue enviroment, and use Disk Eraser.

It accomplishes the same thing, is very easy to do, and you can use it on any pc. No special bios required.
