Intel 8124m board compatibility

[Rand__]

I recently got a 8124m at Ebay and totally did not realize its not a regular CPU (apparently Amazon AWS by an earlier comment in another thread).
So I bought an Asus Z11PA-U12 to run it in since that has 12 Dimm slots and its a 1.5T CPU after all, seemed like a good match

However - when pluggin the CPU in all I got was a red catastrophic error light with no details whatsoever what the cause might be - nothing on Asus page, no documentation, no comments to be found. Tried another CPU in the board - works fine.

So I asked the seller and he mentioned that this is a 240W TDP CPU - at least that's what he found. O/c there are no 240W TDP mainboards out there since the old Scalable CPUs were only rated up to 205W so I asked the seller which board he used to verify functionality.

He said they work on a X11DPI-N, a GA MD71-HB0 and an Asrock he can't remember.

I happen to have a X11DPI-NT (rated 205W) which didnt work, I also tried a X11SPH-nCTPF (205W) which also didnt work...

Now I am at a loss what to do - seller says he tested it and its working fine, but I can't get it to go. Its a nice CPU (18x3GHz with an 3.4 all core turbo) so I am not too keen on returning it (although seller offered), but I am also not too keen on trying a bunch of boards to see if I can get it to work on any of them...

So I found an official CPU that has similar TDP - the Xeon Platinum 8274...
but still have not found a board officially supporting that TDP

Or anything else that can handle a W-3175X, I suppose.

Ah good idea - havent looked in that direction at all, thanks

In my opinion, return it ... As you said. It's a feature stripped version just for Amazon. Other ppl reporting to have these CPU's, never answered questions about how they got it working with boards compatible with the common 8124's. I suppose they might have never got it working. Otherwise, you would need the boards used at Amazon with all the necessary 'hacks' around connecting PSU's, storage, and so on. But what do I know It will be a never ending story.

All boards compatible with 8124's do not have 8124(m) in their list. For a reason I suppose.

EDIT: Check out Asrock Rack EPC621D8A. They are sold on Taobao as compatible with the 8124 and (m) (Link: 铂金8124 8124M正显 18/36 3.0满载3.4睿频3.5 拼6150 6154-淘宝网)
EDIT: I just remember my E3 2673 v3's are on no support list and are working. They were sold just to and for Microsoft Azure
EDIT: According to screenshots from China Supermicro X11DPU-Z+ seem also to work with these CPU's. Not sure smthg (BIOS with microcodes) was modified

I asked SM support whcih board would run the 8274, good chance it would run the 8124m too... unless they removed tohe microcode to save some room... hmm.

For scalable xeon, I recommend use asrockrack EPC621D8A and EP2C621D12 WS (WC621D8A-2T or EP2C622D16-2T or EP2C621D16-4LP may possible support them)due to they support all scalable xeon which we have known include OEM and early ES models. But as we know some motherboard which comes from SM or ASUS, they support up to 255W tdp models but can't sure they can support those 240W or 210W TDP models as those vendor never encourage us to use these CPUs.

I guess Xeon Platinum 8222L this model (200W TDP) can work well with your board if you can find it easily.

Any luck with the gigabyte C621-WD12?

Any luck with the gigabyte C621-WD12?

this board can run 8124M 8259L 8171M 8175M 8179M and other High TDP OEM processors.
edit: looks like only the IPMI version supports high current OEM CPU.
the Gigabyte C621-WD12 VRM can be updated to support TDC=255A which is required to run 8124(M)

 

[111alan]

Almost all Asrockrack board, newer batch of Gigabyte C621-WD12, the 270w version of SM X11DAI/X11DPI, or any 3175x motherboard can do the job.

There are also some Amazon special form factor motherboards which support this on the market, but they always have one problem or another so don't recommend.

Also notice that 8124 and 8124M are different when come to BIOS support. They both require the same kinds of boards(listed above), but 8124 is stepping 3, meaning you need to add a 50653 microcode to the BIOS, while 8124M with stepping 4 doesn't need that.

 

[RolloZ170]

i can confirm the Platinum 8124M SRD1Y H0 works on the following boards:
Gigabyte MU71-SU0
Gigabyte MD71-HB0
ASRock Rack EPC621D8a
PIC

you refer to the Plat P-8124 SR2YS (SKL B1 50653)
there is also the Plat 8124M SR37R (SKL ?? ?????)
________________ Plat 8124M SRD1Y SKL H0 50654)

the Gigabyte MD71-HB0 BIOS R10 includes microcode SKL B1 50563
the Gigabyte MU71-SU0 BIOS R7(and up) includes microcode SKL B1 50563

So I found an official CPU that has similar TDP - the Xeon Platinum 8274...
but still have not found a board officially supporting that TDP

on taobao are some supermicro boards with 270W(up to) support. X11DPi X11DAi X11DPH with VRM upgrade.

i had a X11SRM-F before and this board don't run a Xeon W-2295(165W) even the board supports 165W.
the cascade lake 165W xeon have higher Thermal Design Curent(TDC).

i would open a case at supermicro with your board serial and ask for a VRM upgrade to support the 8274, its worth a try:

Well did not have the best experience with SM in the recent days...
problem is my boards are all out of warrant y so I doubt they'll do that for free

but for the W there is no official compatibility with the regular SM boards anyway, is there?

If this is only a VRM issue - I have an Asus Pro WS C621-64L SAGE (currently running a Xeon W), you think that might run a SR2YS/8124?
just "accidentally bought one and dont even have a board to test it

X11SRM-F LGA2066 suports only Xeon W-2xxx

SR2YS is SKL B1. stock BIOS Asus Pro WS C621-64L SAGE lacks this MC.

Ah my bad, confusing all the SM SKUs

SR2YS is SKL B1. stock BIOS Asus Pro WS C621-64L SAGE lacks this MC.

And too bad Thanks for the info though

Is it just me or did the 8124m fall in price somewhat over the recent months? I see below 400 prices on ebay from China for non-ES/QS parts. This is an Amazon off-roadmap part, right? Are they dumping 1st gen Skylake-SP for 3rd gen Xeon or Epyc in larger numbers?

 

[RolloZ170]

Are they dumping 1st gen Skylake-SP for 3rd gen Xeon or Epyc in larger numbers?

this processors are not needed anymore because the platforms are replaced by 3rd gen scalable or rome/milan.
the price of the 8124M(and other OEM 240W) is so low because there are almost no standard motherboards supporting it.

It's at this price for almost a year now in China if I remember. There's also a 18-core 6139 model at even lower price and support all motherboard types, but the performance is 15% lower due to lower TDP.
