Hi all, first of all, thanks for this fantastic thread: ~5 yrs ago, when i start to build the my first QA88 ES Xeon homelab, i compile info about it from the myriad different sources.
Now i'm start to build new system on QHV8 with X10SRH mobo. Luckily, the bios was 2.0 and it starts out-of-box, but some strange problems persists with memtest86 after some (4+ hrs run) with reporting, like
//
2018-04-05 06:39:28 - [MEM ERROR - ECC] Test: 7, (Col,Row,Rank,Bank): (N/A,N/A,N/A,N/A), ECC Corrected: yes, Syndrome: N/A, Channel/Slot: 0/0
2018-04-05 06:39:52 - [MEM ERROR - ECC] Test: 7, (Col,Row,Rank,Bank): (N/A,N/A,N/A,N/A), ECC Corrected: yes, Syndrome: N/A, Channel/Slot: 0/0
2018-04-05 11:38:50 - [MEM ERROR - ECC] Test: 11, (Col,Row,Rank,Bank): (N/A,N/A,N/A,N/A), ECC Corrected: yes, Syndrome: N/A, Channel/Slot: 0/0
2018-04-05 14:07:57 - [MEM ERROR - ECC] Test: 8, (Col,Row,Rank,Bank): (N/A,N/A,N/A,N/A), ECC Corrected: yes, Syndrome: N/A, Channel/Slot: 0/0
Now i disable the CPU PM features in BIOS (from "Energy efficient" to "Disable"), and suppose it can be useful.

Q1: If somebody have ideas about this type of ECC errors - w/o any reporting the row, col, etc - it can be good. I suppose it's originate in MSR(?) or in some other place in CPU - but not originate to memory.
I seen the some reports about ESXi host OS under v4 CPU configurations is unstable when enabled C6/C7 states in BIOS - i suppose it can be same/similar problem.
Q2: But my original question is around the BIOS update - it's the make sense for my case? I did't able to find earliest changelog in SM, except the official actual one.
Currently, i'm on 2.0, on half year before the v4 was announced:
---
2018-04-05 02:00:33 - SMBIOS BIOS INFO Vendor: American Megatrends Inc., Version: 2.0, Release Date: 12/17/2015
---
but two next updates which i find it - X10SRH6_920 (2.0?), X10SRH7_414 (2.0a), and the actual one X10SRH8_208 (2.0b) - all of them contain 0x14h rev of 406F0 microcode, dated as 02/07/2015. Looks it's the latest one.
Is the any successful runs here of X10SR* mobo with A0 CPU steppings under newest than 2.0 of bios release from Supermicro?
