First board from B&H couldn't return because of their 30 day rule that I didn't think about because I was waiting on other components for the Tower 900 build. When I did open the box there was a very small screw floating around and the standoffs for the NVME.2 SSDs were missing. This board had bent and misaligned pins and with magnification found that a few of the pins were bent backwards which baffles me how the pins could be bent backwards by carefully installing the Threadripper 1950x. RMA the board back and am told it is my fault and need to pay $130.00 on top of my $30.00 shipping charge. Get a replacement board that will power up but won't even start the Live Dash (OLED display.) Returned that board and was able to coax them into giving me a brand new replacement board so I would at least get the standoffs that were missing in the very first box. Any with the inbox board I was able to get it up and running with 64GB of Ballistix Elite RAM flashed the BIOS to 0901. The system reported RAM = 64GB (31.9GB Usable) Followed tech support suggestions and disassembled the water loop for RAM and GPU unseated the memory and reseated one at a time until all eight sticks of ram were recognized and the Live Dash (OLED) display would progress to post the bios.This lengthy procedure made no difference. The system still reported 64GB (31.9GB Usable). Did a clean install of Windows 10 Pro 64bit and the System reported 64GB (41.8 GB usable). Someone informed that it appeared as thou Windows was not seeing two of 8GB sticks. Tech support instructed me to flash the BIOS to 0902 and this put the board back to where it would not post past the memory check. Now they asked me to fill out the RMA form for a return and can not get past the serial number requirement on the form. I started this build in October of 2017 and because of the ROG Zenith Extreme I still do not have a running Desktop. Has my patience been tested regarding this issue???
