Hi All,

Vega 64 Update :

So finally after tons of frustration and repeated failure i decided to divide my vega 64 into (3 cards each) which is very stable when it comes to card detection.
Allthough 4 cards also can run together but at a price of instability because if for some reason the system/driver/power crashes, post reboot 1 card goes missing from device manager. Tried every PCI GEN combination from Auto to 3 but none can fix this instability. For all those who got 6 or 8 vegas running smoothly you guys are really blessed man !!

Present scenario :

Cast miner 0.8
Bloackchain driver Aug release
HBM2 ON
Clock - 1000
Clock Volt - 800
Memory - 1025
Memory Volt - 1100
Fan - 3000 - 4900
Power - -10/-5/+5/+7/+10

Using above changes i wast able to hit only 1950 h/s max in cast miner(+10%) power, 1898-1920 h/s (-10%) & 1920-1940 h/s (+7%) with the last one currently im running my vegas on.

Can anyone suggest me how did you guys achieve those extra 50-100 h/s breaking 2000+ barrier in cast miner. I tried almost every overclocking settings max i only reached till 1950 h/s that too it wasn't constant.

Except for the very first time when i tried running the miner without any proper knowledge of config idk what settings i changed or what clocking i did i got 2200 h/s but with errors.

Please suggest me to cross the 2000 barrier !

Thanks
