I received a X10SRH-CF earlier this week from the linked eBay posting in post 1, as well as a base e5-2603 v3 to test it with until i decided on what to get for a processor - was considering going with a v4, but they are too expensive still yet. Anyways, I tested the board/processor initially with a spare Non-ECC DDR4 Dimm I had available, but the system didn't post. I waited till today when I got in 2x 32GB Samsung RDIMMs (on the compatible list), yet the system didn't post. I swapped the board over into my main chassis with a different PSU thinking it was PSU related, the system didn't post. I have tried without memory, same result, no post.
For all the above cases, I plug the power in and the FANs start spinning immediately. It doesn't jump up to a high fan speed like one would expect to make sure things are working, it is mostly just a constant low speed. After a minute or so the fan seems to slightly slow down audibly, but that may have been my imagination.
Looking through IPMI, i see the "post snooping" code is "ff". Attempting to power-on via IPMI doesn't work. I have also attempted to update the BIOS from 1.0a to 3.2 (latest available i can find), the update says it completes yet the BIOS is not updated when I check the initial IPMI splash page.
Attempting to clear the CMOS by connecting the two headers/soldier points on the systemboard didn't help, nor pulling the battery and letting it sit for a 30 seconds.
Tomorrow i'm supposed to receive the CPU i settled on, a e3-2650l, and will test with it.
I'm afraid it might be a bad motherboard...
