ASUS Pro WS W790E-SAGE SE + Intel Xeon Sapphire Rapids SPR-SP

[RZSN]

So one more question on the Asus Pro WS W790E-SAGE SE ... regarding PCIe lanes.

The manual is written only for the W-2400/3400, and these have 64 and 112 PCIe lanes. All of which are traceable in the manual - the 64L cpu can feed 4x 16L slots and no M2, while the 112L can feed all the 6x 16L+1x 8L pcie slots and 2x 4L M2 ports too. All clear here.

Now what happens when we use a D0 server cpu with 80L ? do we get lucky with M2 ports and the 8L slot, or there will be just one more 16L slot activated ?

Does the W-2400 series monolithic chip have any idle power consumption advantage over the multi-die assemblies?

sure. no EMIB vs. 10 EMIB.
but W-2400 have only 4 mem.channels.

@RZSN as Rollo said. Bottom PCIE slot 6 gets 8x lanes and the other M.2s now work (4x each).
The Layout of the 80 lane CPUs works really well IMO.

@RolloZ170 I've been searching this thread and I can not find info regarding using Optane Persistent Memory 300 series with this board and the QFYS chip.

I could have sworn I had seen it here that it does work. Any idea?

not here, not with W790 - but with QYFS and MS33
WS parts generaly don't support PMEM, so no BIOS options, no BIOS support.
i guess you have seen it here:

edit: post about MS33 and PMEM was deleted, i guess because user arabus was deleted.
