Your factory BIOS timings are strange ... it should go 55 to 77 to 99 to BB but instead it's like 55 to 77 to 99 to 77.

Meaning the timings gets pretty loose from 1125 to 1750 but after 1750 gets extra tight again unless we edited it?

Lets compare.

STOCK Timings on your BIOS

1750 - 999000000000000022559D0031627C4990551313BC0D060C004C04017D0714204A8900A00200712419123138C02D3D17

2250 - 777000000000000022AA1C00B56A6D46C0551017BE8E060C006AE6000C081420EA8900AB030000001B162C31C0313F17

Factory RX 480 timings can hold 2266mhz but like 2188mhz no problem minimal to no errrors

1750 - 777000000000000022CC1C00106A6D4DD0571016B90D060C006AE70014051420FA8900A0030000001B11333DC0303A17

Sapphire RX 580 has the best timings here...
