Oh that's unfortunate. The only thing left to try is to either get a retail cpu and flash the bios via the bios or get a bios flasher which can flash via the SPI header on the boardHi, That's what I tried . Operation is completed successfully but the latest bios is still there . Weird...
Is this confirmed, or just a guess?It seems can't be solved by microcodes,just bugs not fixed in es.
Hi, It seems they fixed BMC firmware (new version is available to download) , I flashed old BIOS 0302 (Seems it's there according to BMC info) but it still stays at post code D1 (As I said out-of-the-box it was working fine with bios 0302) , could they blacklist ESes? No clue for now , also can't check with retail CPU , maybe mobo is bricked hard.Oh that's unfortunate.

I don't think it's flashing the bios correctly.

Not sure if it will help you guys but I just flashed a KNPA-U16 across to get support for the Z ROME ES processors and it is working well. I stopped at version 0302 based on the previous messages in this thread.
There is a bridge bios with PDF instructions here:
Why can't I boot normally with ROME series CPU? | Official Support | ASUS Switzerland
Haven't been able to find the exact same thing for KRPA-U16 motherboards yet but someone on here may be able to work out how to do similar for that model.
Do you have the 0302 UEFI File around? Cant find it in the downloadpage.Not sure if it will help you guys but I just flashed a KNPA-U16 across to get support for the Z ROME ES processors and it is working well. I stopped at version 0302 based on the previous messages in this thread.

Goodmorning! I've also experienced a lot of weird stuff with the KRPA and the only way I was able to properly get a bios flash was via the SPI header. The D1 post code indicates that it's still using the 0501 bios. I know @EdwardTwiss was able to get it to work by flashing via the bios with a retail cpu, so that might be your best bet if you don't own a flasherGood morning everybody, I would like to ask to @ExecutableFix and @yesoos if they fix the Asus KRPA bios problem?
I'm in a similar situation, I have:
- AMD ES ZS1406E2VJUG5
- 8 x 32GB Samsung M393A4K40DB3-CWE (3200MHz) or 1 x Kingston KSM32RD8/16MEI (3200MHz)
- ASUS KRPA-U16 shipped with 0501 bios
I try to flash the 0302 bios via ipmi (with /bios_update in maintenance tab) and it shows correct completition, but if i check again it show up the 0501 version again.
Then I bought a OEM cpu (AMD Epyc 7262) and the system boot fine (also windows works) so I decide to flash the 0302 bios via AZ Flasher and it looks there.
Now the real strange thing: Bios info shows 0302 version, AZ Flasher shows 0302 version, ipmi shows 0501 and I get D1 post error with the ES cpu; the oem one works great.
I'm looking for a solution because i'm becoming crazy!! Was someone of you able to resolve this bios problem? Can you please explain me how to resolve it?
thank you a lot and sorry for my english!
I have some flashers (stuff for Arduino, and motorcycle's ECU) but i have never flashed a motherboard's bios.Goodmorning!

I would recommend the elmor evc because of the included SPI cables that you'll needI have some flashers (stuff for Arduino, and motorcycle's ECU) but i have never flashed a motherboard's bios.
Can you please tell me the flasher i need to use and the exact (and detail please) procedure?
I saw a bios dump in the other thread and @Brainbug spoke about a CH341, is the CH340 good too?
Thank you
Thanks man, at the end I did some homeworks, studied around the web and I figure out that I could flash my bios chip with a Raspberry Pi.I would recommend the elmor evc because of the included SPI cables that you'll need
Hi @setuid0 , I have a working AMD ES ZS1406E2VJUG5 on a KRPA-U16 motherbord. I'm pretty happy with that, the only sore point is the power mosfet heatsink.Hello all here at STH! I have been a lurker here for awhile, this is one of my favorite websites for computer/server info. I don't know anybody here on the forums, but I'm hoping some of you guys can help me out.
I am looking to build an AMD EPYC (home) server. I have NOT bought anything yet; I'm planning it all out first. I want to use the 64c/128t ROME EPYC. I actually need this many cores and I don't care about the low frequency (actually that makes it more power efficient.) This is what I want to build, I am 100% sure of that. I cannot afford retail EPYC 7702p; so I plan to build using the AMD ES "ZS1406E2VJUG5" CPU. Exactly that model number CPU.
I need your help deciding on a MoBo to buy. My requirements are simple: it must fit EPYC (SP3 socket), have at least 8 DIMM slots (for all 8 channels) and it must work with "ZS1406E2VJUG5" CPU! It absolutely must work with this CPU because I'm going to buy that CPU and it needs to work. I'm fine with flashing the BIOS if needed, but I would prefer to have a known working BIOS file ready to flash before I buy the MoBo. I couldn't care less about PCIe lanes or 10GbE internet (NIC.) I would prefer a smaller NIC (as it uses less power) I don't have 10GbE at my home anyways. I doubt I'll use any PCIe lanes. This is for CPU compute. The CPU and the RAM are the heart for me; that and a MoBo that works with ZS1406E2VJUG5 CPU.
I was originally planning on buying a Supermicro H11DSi (Rev 2) MoBo. The extra socket could be useful if I ever get the funds to expand. But after all I've read, it sounds like Supermicro BIOS is hit or miss with the ZS1406E2VJUG5 CPU I'm going to buy. I cannot afford hit or miss. I need this to work.
So I am now thinking about buying an Asus KRPA-U16 MoBo. That is KRPA-U16 (not KNPA-U16) as I cannot find any KNPA-U16 boards on eBay.
@Gabber you got your KRPA-U16 MoBo working with ZS1406E2VJUG5 (or close enough 64 core ES?) As I understand it the 64 core and 32 core are different. I understand the Rome and Naples difference. I want Rome for 7nm power efficiency.
Do the PDF instructions and BIOS zip posted by @EdwardTwiss for the KNPA-U16 board work just the same with the KRPA-U16 board? I really would prefer not to need to buy a Naples CPU because I'm stretching my budget as it is. I'm trying to stay under $2000 with this build if possible. Can I flash the BIOS without a Naples retail CPU? It looks like Gabber was able to do this with an rPi. Do you have that BIOS image from @yesoos ?
Maybe @ExecutableFix could help me? @nero243 had a "detailed guide" that (for some unknown reason) was removed!? A guide for H11 Supermicro board... I'm still open to buying that board if I can get a known working BIOS and some assurance.
The eBay seller of the ZS1406E2VJUG5 CPU just says: "Tested working on Supermicro Motherboard H11DSi, H11SSL-i. Need early BIOS version with Agesa version older before 1.0.0.3."
I couldn't find anything about AGESA for those supermicro boards, granted I started looking at Asus KRPA-U16 boards when I read Gabber's post that he got his working.
I would very much appreciate any help from anyone. I probably won't buy into this build if I cannot be sure that it will work with the EPYC ES CPU, I cannot afford to take that kind of risk.
Thanks!
