ES Xeon Discussion

[RolloZ170]

I guess source of confusion is coming from what I read on ebay, some sellers advertise their QS having model numbers starting with Q1xx but some publish actual pictures of units having model number in SRxxx format

Qxxx is ES or QS. SRxxx is production unit,never QS. the chinese re-print the IHS to hide the original customer of the processor.
i have asked one seller with blind SPR CPU in the listing which QDF/Sspec it is. he anwered that he print the IHS on request.

 

[RolloZ170]

I've tried to ask seller but unfortunately they're reluctant putting CPU into the socket on every random request, receiving a bare picture of FPU from them was the max I could get.

must not be the report, screenshot of this area shows all you want to know.

I see x4 each of DSA+QAT+IAX/IAA, looks like any of 8490H/8468H/8454H
but my problem is getting this data on off-roadmap (private/customer/oem) CPU models they drop onto the second-hand market.

Looking at Intel' consolidated specification sheet it feels like all models having [ V , + , P ] index do have all accelerators, some of H models do as well, Y - only with [+] index (therefore covered by first block), haven't seen much data on C or B index (except for Alibaba's 8475B presumably having all), all the rest aren't good for me (lacking IAX/IAA or QAT)

there is no unofficial BIOS 1.0 for this mobo, no way.
but any stepping D0 (step 6) will work.

Hey everyone, thanks for all your help. I went on vacation for a little bit. Turns out it was a socket problem and I didn't screw the screws tight enough using my cooler.

I finally got around to build up the 8461V @Kizune sent me in August and seem to be in a situation where four (!) of my eight RDIMMs fail to POST on this X13SEI. Two throw "failed component" errors, one says "signal too marginal", and one "fails to train".

I am beginning to suspect this eBay vendor MICRON 32GB 1Rx4 PC5-4800B DDR5 4800MHz ECC Server Memory (MTC20F1045S1RC48BA2) | eBay was less than scrupulous - I paid $40 a DIMM which is like 1/3 of street price and the 50% failure rate could be explained if the DIMMs he sent me were his customer returns, but before I complain to my credit card company is there anyone in the US with a test setup who would be willing to check the DIMMs in question for me?

It may also be CPU seating? The error follows the DIMM, not the slot, but maybe there's some voodoo going on where signal integrity is overall marginal due to some human error...I tightened the screws in a star pattern until then bottomed out which has worked for me in past platforms, can someone with a working system confirm 4677 is the same deal?

bought 2x DDR5 16GB used Hynix from ebay too(other seller) both came DOA with missing SMT components.

aha, spot on. three of the bad DIMMs were missing resistors (?) near the pins and the fourth had a decoupling capacitor ajar.
anyone know what value the 0201 resistors near the edge connector should be or should I just ohm it out?

you could check micron/hynix dataheets, they have mostly schematic and resistor values shown.
these resistors have one open end to the slot, ohming out will work too.
i guess 15 22 or 33 ohm

 

[bayleyw]

thanks. do you know if the other end of the resistor is ground or the data line?

 

[bayleyw]

too lazy to walk over to the microscope but phone camera seems to do ok.

 

[RolloZ170]

i don't see where it is located. another picture pls.

don't find a datasheet from Micro with resistor values,
but Kingston(Hynix) uses 15 ohm there and JEDEC schematics force to use 15 ohm too.

QQ87 is A0 50655, microcode not supported by intel since 2019
Intel / HP latest BIOS lacks this microcode.

Would the 8280 ES QQ87 28C be good for a supermicro Super X11DPG-OT-CPU server? If so what bios version do I need to get right microcode?
What about a SRF81 Intel Xeon Platinum 8273CL? (I've seen some threads with microcode discussion on it too) or
8272CL 2.60GHz 26-Core 35.75MB LGA-3647 SRF89. -- best price on ebay but I've not found much about which microcode.

supermicro still includes A0 stepping microcode. you need only BIOS 2 3.x or higher.

What about a SRF81 Intel Xeon Platinum 8273CL? (I've seen some threads with microcode discussion on it too)

can have issues, but SM BIOS is moddable.

8272CL 2.60GHz 26-Core 35.75MB LGA-3647 SRF89. -- best price on ebay but I've not found much about which microcode.

this is B1 stepping, nothing special. But TDC is 255A, maybe you need a VRM reprogram.
EDIT: with a little chance the X11DPG-OT-CPU does not need VRM modd.

Great info thanks. I noted that supermico says "BIOS version 3.2 or above is required to support 2nd Gen Intel® Xeon® Scalable processors (codenamed Cascade Lake-R)"

So should I be aiming for just the newest if its in all of them.

For the 8280 ES.. any known problems. Is the A0 stepping subject to MDS vulnerability?

sure 3.x i made a typo.
