Because I do not always go to forums now. Actually we were trying to modify the BIOS to support 240w back in 2017, then some time after we admitted failure, our contacts in Gigabyte told us that this can't be achieved by modding the bios, but by reprogramming the PWM. Now people have already been selling PWM modding service on Xianyu like a year ago.good for you and your friend. why are we only hearing about this now?

only the 8124M works on the EVGA. for the W-3175X ES (QL2K) you need to modd the BIOS.IIUC, 8124m and W-3175X ES are failing to run on Supermicro motherboards due to the limitation on the power. I have the EVGA SR-3 motherboard which has been configured to deliver high power to overclock W3175. Does this mean I can use these CPUs on my EVGA SR-3 board?
Wow thanks a lot for sharing this information. So IIUC, 8124M works on SR-3 because PVM on this motherboard is already beefed/configured to support higher TDPs.only the 8124M works on the EVGA. for the W-3175X ES (QL2K) you need to modd the BIOS.
It needs 50652 microcodes. Then it will probably work, if not, I think hardware changes are needed.Wow thanks a lot for sharing this information. So IIUC, 8124M works on SR-3 because PVM on this motherboard is already beefed/configured to support higher TDPs.
QL2K/W-3175X ES does not work on SR-3 because motherboard refuses to boot on non production CPUS. Is this correct, @RolloZ170 ?

the BIOS 3.4 was still limited to 165W, but I wouldn't be me if I settled for that...Guess it would be possible to diff 3.4 and 3.5 and look for a module that reads port 610H MSR_PKG_POWER_LIMIT and fix that latest check up. Or just implant the old module from 3.4 into 3.5. But why, looks like Supermicro no longer wants to be an enthusiast brand.
Wow that's amazing! I am really surprised how WC621D8a can set custom multiplier and voltage. I didn't know that ASRock motherboards can do that; that's pretty awesome.
this board is made for W-3175X, the OC features are minimum, not much than ASUS Dominator/EVGA SR-3/Gigabyte AORUS XTREME.I am really surprised how WC621D8a can set custom multiplier and voltage
the BIOS can be unlocked to make Intel XTU usable on boards without BIOS OC support like the EPC621D8A / supermicro.I didn't know that ASRock motherboards can do that; that's pretty awesome.
china second hand market. but recently there where QL2K (W-3175X ES) on ebay. you have to keep your eyes open.How can I find this 8124 ES chip?
You only need the pinout of TPS53659/TPS53679?asked Texas Instrument for a pinout of the TPS53679, it's not included in the short PDF public available.
got answer now:
"We will need an NDA between your company and TI to share this full datasheet. Is that something you would like us to initiate?"
by the way: got the Datasheet MP2955A from MPS without NDA.
The motherboard supports two Intel Xeon Scalable processors for all server class SKU
