Finally: Overclocking EPYC Rome ES

[mafon]

afaik only with SPI programmer.

Is there any manual how to downgrade with SPI programmer?

 

[RolloZ170]

my H11SSL-i with custom BIOS. What should I do?
How can I find BIOS chip? There are too much 8pins chips.

in the manual it is shown in a socket. between PCIe Slot6 and DIMMD1

Is there any manual how to downgrade with SPI programmer?

you flash what you want.
millions use ch341 - 1000 manuals out there.

It's really strange: the motherboard starts with Epyc 7502 but does not with Epyc 7742 ES with costom BIOS from the archive (on the 1st page).
I have flashed with SPI flasher.
Maybe the problem is here:

Firmware Revision: 01.52.21
Redfish Version: 1.8.0
CPLD Version: 02.B4.02

ZS1406E2VJUG5. The seller told it worked.

So, I think, now I need to find BMC chip to downgade.

 

[mafon]

I found winbond 25q80dvsig chip, but don't think it used for BMC
And also two MXIC 25L512E. Which one is for BMC?

check manual again, there are two in a socket, one SOP16, this is BMC chip.

Rome_H11DSI_Rev1 (16mb chip)
or
Rome_H11DSI_Rev2 (32mb chip)
???

after SPI flash you need to (localy) boot IPMICFG.efi(or other tool) to set correct BMC MAC to get LAN access.

do you know if you try with H11DSi you need two(2) ES right ? one ES does not work, only on H11SSL

He try boot on H11Ssl. And get FF post code with 2.0 Bios and 1.52.21 ipmi firmare.

FF = no life.

Rome_H11DSI_Rev2 (32mb chip)

No. I have 1-socket H11SSL-i, so Rome_H11SSLI_Rev2

 

[RolloZ170]

No. I have H11SSL-i

ok then you need ...
Rome_H11SSLI_Rev1 (16mb chip)
Rome_H11SSLI_Rev2 (32mb chip)

check manual again, there are two in a socket, one SOP16, this is BMC chip.

What manual? I did not find what I wanted.

 

[mafon]

Rome_H11SSLI_Rev2 (32mb chip)

This one, 32 mbytes.

What manual? I did not find what I wanted.

manual of the motherboard (PDF supermicro page)

What manual? I did not find what I wanted.

BMC SOP16 chip below the AST2500 chip. In the bottom left corner of the motherboard.

Nothing about IPMI chip here https://www.supermicro.com/manuals/motherboard/EPYC7000/MNL-2085.pdf

 

[mafon]

MXIC MX25L25635FMI-10G
So, I need 16-pin SOP clip for SPI programmer
