Help to identify Inventec board and supported HW

[ViltusVilks]

I have purchased board on ebay - System Board Dual LGA 2011-3 Socket Motherboard T2652401 | eBay
I know it is Inventec, some sort of B800xxx or B880xxx, but ... no any info on internet. Seller also do not know.

It does not have any vendor specific labels, only MACs and model number

I have working cpu E5 2680v3 (checked on other board) and which is in supported list (by socket/shipset), but not sure about RAM.

MB just do not boot (i have tried only Samsung DDR4 RDIMM. BMC led is blinking, LSB/MSB leds says that it has postcode FE or E7 (according to Intel web site). how to check IPMI do not know,.. should I know IP address (and how to find it)?

There were a lot of these motherboards from this seller, maybe somebody succeeded to boot them? Or know supported hardware list? Maybe I need try to use LRDIMM (locked by vendor) ?

PS: found on taobao one like this but only one 10Gbe - 英业达B880主板 支持X99-2011 V3 V4 DDR4 双路服务器 渲染3D建模-淘宝网

So,.. i do not have BMC debug port header, only desoldered! IPMB (which can be used to intereact with BMC?)

Q is how to get IP address.. just to see BMC board info
Q2 should I try ECC UDIMM 1.2V ram? Or try ECC LRDIMM 1.2v ram?

Ok, just have old router... and... switched on without CPU/memory, picked IP address from router web-ui and checked web-ui of the BMC works fine with default admin:admin

Now question is how to check supported HW, google has no information about it

Here is the G2 version, but it is for v2 CPU, eg C602 chipset
英业达B880G2说明书 - 图文 - 百度文库

B880G2 board supports all types of memory: 24X DDR-III slots, support 800/1066/1333/1600 RDIMM, UDIMM, LRDIMM and LVDIMM

C612 i think supports only RDIMM/LRDIMM because Intel dropped support of UDIMM with v3 Xeons, correct !?

What does these states mean?
POWER ON from BMC not working. eg BMC cant see motherboard even tried to POST

Cleared log and powered-on PSU switch.
i do not have m/b header attached, so no leds, buttons.
also do not have PMBus connected to PSU (have regular ATX PSU)

power-sw/reset button s on header does nothing.

Some little update, just the information for others.
Motherboard booted to BIOS settings even with E5 engeneering sample, problem was that pre-pre-pre-boot checklist waits for power on both CPU sockets (8pin connector), even when second CPU is not installed.

This is why BMC has no any reactions to power-on and event log has this entry, which means - no power
