1705 date code? Very early production code. Checking my records, I had a 602-V341-128SB1705002336 that had Hynix VRAM. It seems .650 is the most appropriate BIOS version since it has Hynix and was produced prior to May 2017. The BIOS linked below is an untouched retail copy and does NOT have tweaked timings or mining timings.
