[Solved] Check Bios for the possibility of ECC support

Please can somebody help and check my BIOS file for the possibility of ECC support?
It is a InsydeH20 Bios for a sockel 1151 system with iNTEL c236 chipset (a DFi Mini-iTX SD106 variant).
If I use a XEON E3 1245v6 and ECC Memory (DDR4 ECC sodimms) with it system won’t boot …
Non ECC memory works without problems.

PS: Sorry for my poor english!

@test.it - either that memory is faulty, or is not compatible, I checked your BIOS and ECC support is already enabled by default

ECC Support, VarStoreInfo (VarOffset/VarName): 0x10D, VarStore: 0x2, QuestionId: 0x1A2, Size: 1, Min: 0x0, Max 0x1, Step: 0x0 {05 91 68 12 69 12 A2 01 02 00 0D 01 10 10 00 01 00}
One Of Option: Disabled, Value (8 bit): 0x0 {09 07 5E 12 00 00 00}
One Of Option: Enabled, Value (8 bit): 0x1 (default) {09 07 5D 12 30 00 01}

@Lost_N_BIOS - Thanks for helping me!

Mmh, I try two different types of ECC Memory that works on other boards (PC4-2133P-TG1-11 & PC4-2400T-TG1-11), unsuccessfully!
There are any hidden options in the Advanced BIOS Settings that can help me?


You’re welcome. Maybe only certain density will work, is both kits you tried single or duel sides? Ask the company for a list of known compatible ECC memory.
Here is all the BIOS settings from the setup module in textual form (IFR), hidden ones are in there too, scroll through and see if you see any you need changed for ECC to work properly.
ECC support setting is at 0xBA641. If you find any you need changed, make a list for me of the exact names of the setting and what you want them changed to and I can change for you.

Now it will be “funny”, I checked exemplarily the connection between socket and SODIMM slot (socket pin AY31=ddr0_ecc_[7] and SODIMM_0 pin 104=CB7) and no connection! Crosscheck with a board that works with ECC RAM, connection.
So, it looks like DFi doesn’t wired the necessary pins…

Make your own connection from backside of board?

16 wirings , no way at the moment

Make one connected at CPU, then long run to each memory bank area, then branch it off to each I know what you mean though, sounds like a tough mod to do!

I wonder why they have ECC enabled in BIOS, then hardware missing from the board, you should ask them in email (they seem responsive to customers usually)
