Intel 8124m board compatibility

[RolloZ170]

now that the QL2K(also known as Xeon W-3175X ES) is running on my X11SPM...a few BIOS mods and Intel XTU started, voi·là
(don't want to hurt the VRM power stages, so limited to 205Watts)

QL2K

good for you and your friend. why are we only hearing about this now?
ElmorLabs $32 USD

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.

There were a lot of good stuff here, for example, a resistor mod to allow some X11 to support ES cpus. Just, by seeing fanboys defending their brands to the death, most of us no longer have enough motive to share the knowledge outside now. Sharing info could bring a lot of troubles while gaining nothing good now.

Of course, I always keep my PM channel open

thank god that is not required for LGA3647 ES.

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?

only the 8124M works on the EVGA. for the W-3175X ES (QL2K) you need to modd the BIOS.

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 ?

Yes, even the 240w ans 255w version of 50652 do not need that mod.

It needs 50652 microcodes. Then it will probably work, if not, I think hardware changes are needed.

Yes, Boards designed for 3175x can also support these 240W amazon cpus.

cascade lake non production ES works.
the BIOS must fully support Skylake and Cascade Lake processors, there is no space to add. skylake non-PRD ES support.
all modd avail. to make BIOS compatible with skylake non -PRD ES ist to downgrade the processor initialsation codes to an pre cascade lake one.
if you take a skylake only BIOS, i.e. at the supermicro X11SPM, skylake B0 ES are supported(most,not on all supermicro's)

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.

the BIOS 3.4 was still limited to 165W, but I wouldn't be me if I settled for that...

205W on X11SPM BIOS 3.5

How did this CPU hit 41 multiplier on an SM motherboard? Is 8124m unlocked?

sorry, this is not 8124M. its Xeon W-3245 ES
i have a unlocked 8124 ES laying arround.

Two 8124m's (SRD1Y) running great on the ASRock Rack RM237-C622LM, no bios or VRM mod. Also have a 8124m (SR37R) running smooth on EPC621D8a, no mods needed either.

here is the 8124 ES QLJ1 Overclocked a bit, some additional Core voltage required.

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.

How can I find this 8124 ES chip? I assume it is something special and cannot be found easily on EBay

 

[RolloZ170]

this board is made for W-3175X, the OC features are minimum, not much than ASUS Dominator/EVGA SR-3/Gigabyte AORUS XTREME.

I didn't know that ASRock motherboards can do that; that's pretty awesome.

the BIOS can be unlocked to make Intel XTU usable on boards without BIOS OC support like the EPC621D8A / supermicro.

How can I find this 8124 ES chip?

china second hand market. but recently there where QL2K (W-3175X ES) on ebay. you have to keep your eyes open.

 

[RolloZ170]

Wow that's amazing! I am really surprised how WC621D8a can set custom multiplier and voltage

i can do that on my X11SPM-F too with Intel XTU. but the VRM is not that massive than the one of the WC621D8A-2T.

is it supposed to be QLJ1? For example this one is QLJV:

QLJV is unknown to me, will be locked. newer saw a QLJ1 on ebay. but you can buy QL2K and disable 8 cores.

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.

You only need the pinout of TPS53659/TPS53679?
If so, it is available in Open Compute Intel motherboard schematics:




I took it from Project Olympus Intel XSP Motherboard -- Electrical Collateral zip file (page 163 and 171).
Is this enough?

I've got this exact motherboard and it has both TPS53659 and TPS53679, so they both need to be updated?
According to BOM, there are 7x TPS53659 and 2x TPS53679.
Also, this board has no support and no BIOS updates at all, so would it be possible to read BIOS, manually patch it and flash it back to support P-8124 SR2YS? Although it's from Microsoft, so if they had custom OEMs, maybe Amazon OEMs will work too? Or it doesn't work like that? According to some people, it does seem to support 1st gen ES chips... The docs say:

The motherboard supports two Intel Xeon Scalable processors for all server class SKU
