ES Xeon Discussion

[RolloZ170]

All i wish now is i can find it in the D0 stepping to put into my Asus WS until Xeon W7-34xx ES/QS/Prod will come down because W7/W9-35xx hit market and these will be replaced. This Gold is... well - pure gold

haven't found any MCC D0 350W ES
but Q071(MCC) is very close, only 270W goes to 3500 all 32 cores.

GIGABYTE MS33-CPA MB für Intel Xeon Platinum 8490H ES LGA4677 350w 60C/120T | eBay
I pay 380 Eur.
And 4 Kingston Fury renegade pro 4x32GB also 380 Eur.
And one QY36 for 105 Eur with VAT.

So how is your build. I am considering buying this board. Is it worth it? Not too many pcie slots! Is this a good motherboard?

except the 2 PCIe slots and the OCP3 PCIe 5.0 it is same than MS33-AR0 or MS33-CP0.
it runs any ES, D0, early E0, late E0 and all other.

Not work with the oc memory kit,2 week later coming another 8 micron 4800mhz standard module.
I think good board but if/or you want sound card,vga,ssd not so good.
I have another one this is Asrock W790ws very good board!
8480+ es working fine,with 4200Mhz turbo.

be fair. that's comparing apples and oranges.
btw. i have Kingston fury renegade pro 5600 and 6000s working fine but of course they run @4800 because server boards usualy don't support XMP or EXPO.

So is worth buying this motherboard for 370 euros?

wait, are those extra MCIO 8i slots? if so, can they be for anything other than system integration?

Um, a hundred people, a hundred opinions. Hard to advise. It depends on your options and preferences.

If you want now using D0 or buy now or in near future cheaper qs scalable pieces, so you must buy C741 boards. In my eyes looks best c741 maybe GIGABYTE GIGABYTE MS03-CE0 because I prefer more available PCIe5 slots.

But if you want OC and faster memory modules and few more additional bonuses (audio tons usb wifi etc.), and it is not problem stick with D0 and wait on lower price w-pieces sometime in the future, or buy now more expensive w-piece, so W790 boards are for you. One big minus for W790 boards is that not support cheaper qs scalable pieces. But for example this is not problem for me, I am happy with my D0 and I have not problem wait on lower price w-pieces. In my eyes looks best as w790 ASUS W790 SAGE or ASROCK W790WS (1rev).

U2_P0_4AC (2x 4 lanes)
U2_P0_4EG (2x 4 lanes)


U2_P0_5AC (2x 4 lanes)
U2_P0_5EG (2x 4 lanes)

U2 = NVMe devices. the connectors are not usable for GPU e.g.

summing up the slots and conns:
PCIE_7 = 16 lanes
PCIE_6 = 16 lanes
OCP1 = 16 lanes
U2_P0_4AC = 8 lanes
U2_P0_4EG = 8 lanes
U2_P0_5AC = 8 lanes
U2_P0_5EG = 8 lanes
80 lanes PCIe 5.0 total

In my case, I already have an 6438y+ xeon gold CPU, which I guess it is not compatible with W790 boards, isn't it? And for the price, the GIGABYTE MS33-CPA seems like a good deal, the only part I don't like it is that you don't have so many pcie ports!

correct: SPR-SP (EV-)QS or retail are not supported by W790

cool! is each of them pcie Gen5x8?

all are PCIe 5.0 (same on MS33-AR0, MS33-CP0 )
but U2 = NVMe

 

[painkoyo]

the fly in the ointment.
but at least for me, two GPUs are quite enough, so the expandability of this motherboard seems not that bad.

what cable to use for connecting u.2 nvme? Can you connect more u.2 nvmes to one port U2_P0_4AC ?

 

[RolloZ170]

what cable to use for connecting u.2 nvme? Can you connect more u.2 nvmes to one port U2_P0_4AC ?

yes: 8x U.2
U2_P0_4AC = U2_P0_4A(4i) + U2_P0_4C(4i)
MCIO 8i to 2x U.2
edit (SFF-TA-1016 8i to 2 NVMe U2 SFF-8639)
better search for a NVMe backplane with temp sensors like used in server chassis.

 

[painkoyo]

yes: 8x U.2
U2_P0_4AC = U2_P0_4A(4i) + U2_P0_4C(4i)
MCIO 8i to 2x U.2
(SlimSAS SFF-8654 8i to 2 NVMe U2 SFF-8639)

Ah, i'm not sure about whether SFF-8654 and MCIO are equivalent in some case. i've been puzzled for a while.
MCIO 8i SFF-TA-1016 vs SFF-8654 8i - are they mechanically and electrically interchangeable function-wise? (with loss of bandwidth)

i don't know exactly. most sellers write MCIO with SlimSAS SFF-8654 in one line thats the problem.
maybe ask gigabyte for a part number.
you need a fitting cable -> 2x U.2

top SlimSAS
bottom MCIO

 

[UhClem]

The more general problem, applicable to almost all tech products, is that most sellers (the vast majority) are either incompetent or deceptive/dishonest (or both).

you need a fitting cable -> 2x U.2

That (linked product page) is most likely a counterexample. [e.g., precise terminology, with no contradictions. and (bonus) legit-looking wiring diagrams]

also something like this:

MCIO PCIe gen5 Device Adapter x8/x16

two MCIO 8i inputs one PCIe x16 electrical/mechanical output PCIe gen5 - high quality Amphenol SMT slot, 85Ohm PCB, optimal traces the vertical model can be placed with single width spacing can work in x8 mode with one cable (input near the power plug) can work in x16 mode with both inputs...

c-payne.com

might convert mcio to pcie slot. Not sure if 2 x8 mcio would work as single x16 pci though. But mico x8 to pci x8 (mechanical x16) should work in theory.


I have to say, that's an awesome thread, lots of useful info. Thanks a tons guys for sharing it.
