Sapphire RX Vega 56 sold by NewEgg.com on eBay w/free shipping: $419
I have 2 such cards. They can't work normally with 950 MHz HBM overclock... Should I maybe rise HBM voltage?..
no wonder they are so cheap.
if stupidly overclock just by moving sliders in any overclocking app - then yes - they cant hit even 950 (artefact all over screen 100%). with undervolting reg mods it works 1100 very good.
