When I contacted the brand JINGSHA (KINGSHARK), and asked about ECC support, they didn't even bother to reply. One of their other sellers said it was not possible.
I specifically bought this X99 board from Diego because he promised good support.. and he delivered. Above and beyond. After talking with him, he went out and hired a BIOS engineer to get ECC working. That's expensive.
Developing a product and resolving issues takes blood, sweat and tears. You're asking me to steal this persons hard work. I won't do that.
If you want working ECC on this board, you have a few options:
* develop it yourself. From my research, the ME does MC initialization so setting it to the server chipset should be enough.
* wait for an alpha release of open core (open source) I'm working on
* ask szmit for the BIOS.
* buy the board from szmzit. They have the best pricing, even on Taobao.
FYI - I don't receive any money from this. I'm only recommending a product I found to be useful from a stellar seller.
