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
Are you using PP Table mods? Looking at your settings, it doesn't appear so. Your power draw is probably through the roof which may lead to throttling due to temps.
I encourage you to read through the following threads/guides:

No im using sapphire default overclocking tool.
Also the temps are between 65-68 C & TDP is 850-920 for 3 cards (inclusive of cpu+board)...........should these figures be a matter of concern or are they normal ?
