Post Code B7 after bios flash #50

Description : X99-F8 Motherboard BIOS Version : 1.0 Date : 2021-5-11

My system was working normally before I try to flash the tinkered Bios. Processor: E5 2620V3 Memory: Atermiter 2x8GB DDR4 3200Mhz ECC ( Slot A1 and B1)

First I've backup my original Bios using Mi899 procedure.

Then I tried to flash the "Stock Huananzhi X99-F8, TU PEI -50/50mv", process completed successfully. After reboot I've got stuck at posting code B7. I've tried to change slots, use only one memory card etc. As the code represent "B7 Reconfigure NVRAM settings." I've decided to try another memory card. I've used a GEIL 8GB PC4-28800 CL18-22-22-42 1.35V at slot A1. And after several different beeps (first 3 beeps and then a long beep) at different posting codes the system entered in the BIOS setup. I've saved and exited and computer booted up in Windows.

Then I've flashed back my original BIOS, shut down. Changed back to the atermiter memory as previous configurations and it all worked right.

The second time I've flashed either "Stock Huananzhi X99-F8, TU FSS" or "Stock Huananzhi X99-F8, TU FSS -50/50mv" I don't remember correctly. And the same results happened. Stuck at B7. So I did the same procedure changing memory card. And when entered in the Bios I've ended up rewriting boot, which resulted in a dead motherboard at posting code FF.

Now I'm in the process of flashing my original Bios with the CH341A programmer. BIOS Chip is MX25L12833F.

I don't know exactly but it seems that newer motherboard might have a complete different BIOS. hz-x99-f8-20211014-153945.zip

update: I've successfully flashed original Bios using CH341A and everything is working again. I've uploaded my original Bios dump. It might be be useful to you or someone else.

The latest revision of Huananzhi X99-F8 / T8 / TF is not compatible with the original BIOS, it also seems like the latest revision with the latest BIOS has better RAM compatibility.

Unfortunately, here I can't help much, instead I suggest you to follow this issue: Error F9 (possible a different cause to a previous reported F9 issue) #28.

I also plan to review the latest Huananzhi X99-F8 revision, but it's not gonna happen soon.

With this I close the issue, since it's not related to Mi899 itself.

How long do you think it can take until you do a review of the new revision? I don't mind waiting as I still don't have a good graphics card to take advantage of this processor (20-40% of use gaming with GPU at 99% XD), it's just to know.

Maybe a month or two.
