I just want to thank everyone for being so helpful in this thread. Special thanks to Hellae for his reddit guide and Oldcomer's hardware for his YouTube guide. Just set up my two rigs today running 8 Vega 64s. I am at a combined 15300-15600 hashrate (pool just shows random numbers but calculated total hashes over 7 hours turn out around these numbers).
Running fine for 7 hours. Each system is consuming around 700watts from the wall, one has a killawatt and the other the Corsair RM1000i with Corsair link showing 700W and 93% efficiency on 230v. Hashrate seems a tad low but I had to leave shortly after putting them to work so I had no time to tinker.
One has a running monitor plugged in but I started the second one through TeamViewer (had disconnected the monitor while off) and seems to be running as well as the one with the monitor, maybe HDMI dummies aren't required after all!. I still ordered two and I am waiting for them. Both have onboard gpus as primary. I got two i3-4170s just because I might use them for other projects in the future (AES-NI support). 1000watt PSUS seem just fine so my advice is buy them if they are cheap instead of 1300+.
Have fun, I am!
would love to know how you are managing to run 8 Vegas on 1 x PSU. an only 1 Corsair RM1000 even.. Most of my rigs with 7/8 Vegas 56 are suffering from PSU issues and I have to power them with 2 x 1200/1000 or 1200/1600 etc etc.
sure you can tweak the cards to lower voltage but i think the initial bump at the start makes them a tad bit unstable.
Cheers
I think he is running 2 rigs with 4 vegas each
Otherwise hasrate would be a lot weaker than just a tad low (975h/s). Also 700W seems like a normal consumption for 4 vegas, even a bit high if aiming for 150w per card.
So im running 2 vega 64s and 2 vega 56 flashed to 64 bios.
Did soft power play registry.
Im getting about 7700-7900. but some times it seems to drop to around 7600.
Other problem being my total power at the wall ATM is 940W seems high to me.
my sysem idle is around 50-60w.
Any ideal on howto bring the power down to the 130w even 150w each?
SO i did have everything up and running wattage was still alittle high but i can live with that.
then some how i lost everything.
Have done:
---DDu
---Reinstall blockchain driver
-- it took a few uninstall and reinstalls to pick up all cards again, Some showed up at RX vega(tx) in device manager.. any reason? now they are all back to just RXVEGA
i have 9 folders in my registry now.... do i need to remove some?(and how)
