ASRock z170 MOCF lives on Coffee Lake Mods

I just found my way to this topic via another site and I m pretty excited about this MOD. Some quick questions though:

- so I boot regular (skylake or Kabylake), go to BIOS overwrite my 7.60 with 7.51D and the insert Coffe Lake CPU (modded)?
- does my Skylake work with the modbios afterwards, or not? I read somewhere above that Kabylakes work
- The 7.51 seems to not include the Meltdown/Spectre microcode, correct? So the CPU is not protected then?
- What exactly is those 2 pins that we are connecting? (on Kaby and on Coffee), so what am I connecting?
- do you see the chance that Windows will get an update/patch/Microcode that will prevent this mod from working ?
- I assume the power draw of the 8700K is something higher than 6700K (which I own), the OCF should be able to handle this, right? I dont suppose I need to connect the full 12 EPS-pins? (Currently I am only using the 4+4, but the OCFM does only have 4+4 anyway).

Thanks for answering this.

Hello flautze!

I've checked this Rev. 7.51A/D BIOS and it's updated with latest CPU micro-code for SkyLake (C2), KabyLake/CoffeLake (84) that Intel released to mitigate Meltdown/Spectre (https://newsroom.intel.com/wp-content/uploads/sites/11/2018/03/microcode-update-guidance.pdf) so you'll be able to use your i7 6700K and/or any KabyLake/CoffeLake and you'll be "protected". 

As stated by Splave you have to flash BIOS with a SKL/KBL CPU, shut down the MoBo, swap CPU and power-on.

Cheers,

KK

MB ASRock Z170 Extreme 4

CPU 8700k

BIOS mod: https://drive.google.com/open?id=1hvskCy4DWEEcQzInyh6ZfqwZNGBY4nhl

but the motherboard does not start.
Post code 00 and off.

Can someone help with the BIOS mod?

[Splave]

You will need to find the equivalent of this mod and solder the mobo. IDK if the extreme 4 VRM is strong enough though if you plan to overclock it.

[labeanchik]

This task is almost impossibleI. I hoped that everything would be more optimistic.

[labeanchik]

need to find these 2 pins on the board that come from the socket. after - connect them with a wire?

how will I find it?
I do not have a boardview.

This is it ?

Hey there. Photos show other way you can connect the SKT_OCC pins of the socket together: Either way does same thing, it tells the board that there is a coffee lake CPU inserted into the socket. (because that function moved in coffee lake to a different pinout location)

 

 

 

 

[labeanchik]

But SKT_OCC  and GND connected here:

i solder here. In doing so, removed the jumper on the processor.
But start post code 00 and off.

Maybe it's in the bios?
Could you make a BIOS under z170 extreme4?

[Splave]

You still need the mod on back of cpu

[labeanchik]

where exactly ?
Here ?:

if there, then I tried both options at the same time - the situation is similar.

Then it's not missing the SKT_OCC, which means it is not your problem.

I can not understand now, why so?
I found a link where worked 8700k on extreme4, but I'm not sure if it's true.

@labeanchik

Here is your bios, you have to flash with an SPI programmer to downgrade the ME region to 11.6:

Based on: 7.50 ME: 11.6.0.1126 Microcodes: 06EB(0x84), 06EA(0x84), 06E3(0xC2) Tested with: G3900, 8700K

Maybe someone will try an 8700k with a Z170 K4/D3. DDR3 OC on Coffee Lake?

That board needs a hardware mod for Memory voltage or a bios with 2.1 volt upper limit.

Not Worked. 6700k and 8700k not work.

the post code behavior is identical, both on the 6700k and on the 8700k.
now 8700k is not included in the post code 00.
Began to heat up, like 6700k.

Last post code 78 and cycle reboot
in manual: 61 - 91 Chipset initialization error. Please press reset or clear CMOS.

@Splave will Nick or anyone else do stability updates for the MOCF / OCF? Or nothing planed?

[labeanchik]

F**k.

- 2 contacts

This BIOS doesn't require any HW mod on the motherboard, you just have to short the 2 pin on your cpu.. Just clear cmos and bios settings. The 6700K still boots fine in the old BIOS? And this BIOS is based on the Z370 Killer SLI

[Splave]

Hey that is why you should cover these pins

6700k still boots fine in the old BIOS.

I somehow restored these contacts.
they do not play a special role.
6700k works well.

6700k works well and without these contacts.

I admire your determinantion. 

[labeanchik]

I asked for BIOS from z170m oc formula Z17MOCF7.51D_CFL
with it started, but because of bad contact with the socket - in some position of the processor - it does not load ..

with BIOS  Z17MOCF7.51D_CFL - a lot of things do not work on my z170 extreme 4
