EPC621D8A & Xeon-W CPUs

[Rand__]

Hey,

Has anyone successfully run a Xeon W 32xx on a EPC621D8A?

If so with which Bios version?

Its officially supported since P210, but its not working - just getting CPU Overheat, no screen, no boot.
Contacted Support but they dont have an idea yet whats causing this.
Tried three different Xeon W's (one ES, 2 retail) , regular Cascade lake Xeons work just fine.

Thanks.

should work. i have a 3245(205W) QS QRMM/QRD7 ran on
EPC621D8A P2.10
EPC621D6U-2T P2.20
WC621D8A-2T P1.10
X11SPM-F (modded BIOS 3.5)

Hm, any idea why it wouldnt? The cpus run fine in my Z11PA-U12 and C621-64L

 

[RolloZ170]

bad BIOS or bad mobo revision.
which BIOS ?

L22 - think 21 might work better? Got it from support for another issue with GPU (which turned out not to be a board issue, but windows 10)

Board Rev 1.02

Bat 0 Volts ?
have you at least one DIMM per MRC installed (A1/D1)?

 

[RolloZ170]

L22

check 2.10

Yes. 2133's

And as mentioned no issues with same config with 6230n

you don't want to know what it is ?

there is a Beta 2.22

Xeon W have 64 lanes.

 

[Rand__]

check 2.10

nope

Xeon W have 64 lanes.

I know, but mentioning it since the board at least boots with that one. Just not -W's

there is a Beta 2.22

You'd think support would have mentioned that... but I think they are as lost as I am

 

[RolloZ170]

last official is P2.10 so i would check it first.

 

[Rand__]

I just did, no go.

 

[RolloZ170]

I just did, no go.

checked pictures, i had rev. 1.02 too.
BIOS update Instant Flash or IPMI ?

 

[Rand__]

Instant Flash

 

[RolloZ170]

OK, are the NVDIMM Jumpers set to NVDIMM ? Xeon W don't support this.

 

[Rand__]

Both on 1-2 (I assume, its in direction to the cmos battery / board center)

 

[RolloZ170]

sorry but i have to ask. any motherboard standoffs shorting the pcie lanes 47-64 ?

 

[Rand__]

perfectly valid question - it resides on its box while i run tests
