Question GTX1080 amp edition Memory clock stuck at 405MHz

[rc4922master]

well i think this was caused after a bios update im not to sure, but after finding why my frame rates were sucking in game i contacted zotac to see if i could get the corect bios for my GPU ZT-P10800C-10P and flashed my bios through fire storm
here is the link they gave me but my mem clock is still stuck at 405 after the flash.
