6450c had 16 PCIe lanes cut, leaving 64 lanes remaining.
Quite enough though

Thanks everyone, alright then, ordered CPU from kuaka03 for $119 incl. delivery/taxes
(then I think it will be extra +3% for FX from my bank,
there's no import duty chargeable because import value is less than £135 as per UK customs rules).
Should arrive in first week of November.

Hey Rollo, thanks so much for such detailed high quality information. Is it not wise to get a Dell F4Y1M T5860 Precision W790 motherboard for use with Xeon ES? They are $260 right now on eBay, which is suspiciously low for a 4677 board. I don't care about the all-core OC, I just need the multiple cores and single socket design. Right now the E stepping Xeons are around $500, beyond what I'd want to pay for an ES CPU unless there are sub $200 ones. The D0 ones are so cheap, nearly $100 for 56c/112t QYFQ D0 Step 3.
imho not wise. D0 not supported. early E0 maybe, not tested.
no Dell warranty, to use with serial/licence of your defective board.
Dell = all propretäry parts.
don't work. only ASUS/ASRock W790
tried to get cheap ram by buying "used/untested" for Asus w790 ace. one of the sticks gives an error code 29, the other gives error code 53 which is "
Memory initialization error. Invalid memory type or incompatible memory
speed
"
SK Hynix pc5-4800b-ra0-1010-xt both 64gb sticks anyone else tested these?
i assume theyre broken and im getting burned for trying to cheap out lmao

i bought form ebay first too. 2x 16GB both DOA (missing SMD parts)
no but should work.
yeah guess theyre both just dead then if they should work i tried like 4 different bios versions, ordered some of these on amazon https://www.amazon.co.uk/dp/B0BYSS6M8K
Got LGA4677 Xeon Gold 6450C 30C/60T SRMHJ (low-frequency 1Ghz) couple of weeks back,
just had no time to test, today plugged in and so far seems all is fine
(although there were some mechanical defects, including slightly damaged capacitors on edges {falling off shelling/soldering, one end even almost without any soldering left} on MB contacts side),
detected instantly with BMC results below
Upd - HWInfo64 attached. Looks like it at least has QAT and DLB accelerators.
p.s. please note - I've disabled lots of features in BIOS for initial run to reduce number of potential issues to deal with,
therefore some extra functionality might be actually available but reported as not.
Upd2 - added screenshot with HWInfo64 sensor status during benchmark (Power limits / Frequencies / Temps)
CPU Package Idle/min <=20W
Upd3 - generally it looks like Xeon 6450C SPR CPU model offers (CPU-Z bench in spoiler below) same multi-core performance as parallel Golden Cove based product for desktops (12th gen Adler Lake) model i9-12900K which has 8 P-Cores (Golden Cove) at 3.2 Ghz base (3x times higher than 1Ghz) and 8 E-cores. This is with two RAM sticks (can plug all 8x RAM modules but doubt it will make much of a difference).
Current price for this desktop CPU is 3x times higher (£270) than that similar bench-points (in multicore mode) Xeon (of course MB+RAM reverses scales back) costing me £95.

I have an Asrock W790. My current CPU is a W3-2423 that I got for $40 to test the system (got it cheap and repaired bent pins), so I can only go up from here. If I want to use this system as my daily driver/workstation, should I stick to W-type Xeons and spend the money for one of those as appropriate to my workload, or would one of the D0 Xeons work just as well or better?
I was considering the Q071 Platinum 8462Y+ for speed+cores or the Q079 Gold 6444Y for the fastest base speed SPR I could find. I also looked for 6416H ES/D0, but I couldn't find it. Another one I saw but don't have any information on is the Q2Y8 Emerald Rapids, but I don't know if that would even work at all like the D0s might. My main interest in that one is that it may have generational improvements, but it seems to be a 4516+Y Silver if I had to guess.
Are there any pitfalls I might encounter? Are these CPUs not recommended for any reason? Thanks!

keep in mind SPR-SP D0 XCC support can be dropped by any new BIOS.
avoid MCC models(E1B), seems they don't work on ASRock ( many negative reports )
EMR (WS/SP) is not supported by W790. D0 and early E0(e.g. Q03j,Q08S) is only SPR-SP stepping working.

Then it seems that I haven't done enough research yet as I wasn't aware of the Asrock incompatibility with the MCC. 8462Y+ is listed as XCC according to Intel's sheet despite having E1B on its IHS - is that one still likely incompatible/reported as incompatible anywhere? Is there a spreadsheet somewhere with D0/E0 and motherboard+BIOS version compatibilities?
I also found a QY0E that doesn't appear to have any hits on this thread when I searched it - I wasn't considering buying it especially since it seems damaged, but I'll link it for documentation: Intel ES Engineering QY0E Xeon Gold LGA4677 2.2GHz Processor Sapphire Rapids | eBay

8462Y+
E1B = MCC.
ES brand string = "0000" so don't compare "0000" vs "8462Y+"
MCC came very late, there some ES models in both XCC & MCC.
Q071 not work on ASRock. retail 8462Y+ work only on C741 motherboards
never seen working: no data except D0 stepping and base clock.
if you need high clocks take a 48/56core model and disable half of the cores.
yes,
EMR-SP gold Q30G 48C A0 ES2 330W,
EMR-SP plat-N Q2T7 52C A0 ES2 300W,
EMR-SP plat Q2SR 64C A0 ES2 350W.
edit: there was a typo at the first one, sorry.
