I'll be adapting universal VRM cooling plates from Watercool, so no problem if there's no uniblock planned.

Hi Guys .

Here is the PWM info of Asrock X299 mobo.

Asrock X299 OC formula
Asrock X299 Professional Gaming I9
Asrock X299 Taichi

These 3 model use same 12 (Core)+ 1(VCCSA) phases

VCORE 12phase
ISL69138+ ISL6617*6 (pwm doubler) +ISL99227*12 (DrMOS)

VCCM 2phase on Both AB and CD channel .
ISL69138+ ISL6596*2 (driver) + FDPC5030SG*2 (dual-NMOS)


Asrock X299 Gaming K6
Asrock X299 Killer SLi

These 2 model use same 10 (Core)+ 1(VCCSA) phases

VCORE 10phase
ISL69138+ ISL6617*5 (pwm doubler) +ISL99227*10 (DrMOS)

VCCM 2phase on Both AB and CD channel .
ISL69138+ ISL6596*2 (driver) + FDPC5030SG*2 (dual-NMOS)


Asrock X299 E-Itx

VCORE 6phase
ISL69138 + ISL99227*6 (DrMOS)
VCCM 1phase
ISL69138+ ISL6596*1 (driver) + FDPC5030SG*1 (dual-NMOS)





So far X299 OC formula can handle 1000 watts loading by Cinebench R15 without any problems . It is confirmed .

Any idea when we'll be seeing the OC Formula released?

Infineon OptiMOS 5 BSG0812ND spotted on the ASUS Mark 2: https://www.hardwareluxx.de/community/f12/lga-2066-mainboard-vrm-liste-1167715.html#post25685397

Edit: Forgot about the way hardwareluxx handles guests, here are the photos:

I can't find a public datasheet but there are such for the 0811 and the 0813 and their efficiency looks awesome, especially when it comes to switching losses.
elmor or Raja, can anyone of you confirm if those VRMs driven by the ASP1405I do run in 7+1 or 8+0 configuration on the Mark 2?

how about other asrock x299? are they suffering from the vrm overheat?

This is simple math. If you try to have "none" air flow on PWM.

Then the balance temp of VRM will be determined by the size of heatsink and volume of heat.

But based on the regular AIO cooler . 300-350 watts from CPU side will be the maximum heat can be handled. or cpu will be overheat and reach Tjmax.

Replacing thermal paste by liquid metal will be the best solution with aircooling . CPU temp will drop lots and heat conductivity will be much faster.

It will also help for reducing temp of VRM.

Is the PCB layer count higher on the OCF by any chance?

8 layer is more than enough. key is the core material .

What about switching frequency for your boards Nick? I'm curious about it due to the fact you went for doublers in nearly every X299 design.
