Mine seem to crash a lot
Motherboards make a HUGE difference. I only use higher end ones. The little extra is worth all the time and headaches saved.
Powersupply is another big thing.
I went for an ASUS B250 Mining Expert and have a v64 and a v56 @ 64 along with a 1080 ti running stable. My main issue to date has been trying to get power draw at the wall to resemble hellae and everyone else's whilst maintaining high hash rates. I've found that the only way to curb power draw is to set core to go 1308/1100 @ 905 mV on both Vegas, 1408 core increases power draw at the wall by 100w for a ~200 h/s benefit. With the 1080 ti mining Zcoin (135w) total system power draw at the wall is 495w and the Vegas hash at 3650 h/s. That's not as good as I had hoped and I'm beginning to think the motherboard is the culprit. Power supply is rm1000x so I don't suspect that is the issue. Risers are 006c powered via 6 pin PCI-E, could they be causing higher power draw? Have followed all the guides and used hellae and my own custom power play tables - this has me stumped...
1408mhz causes thee high powerdraw. I am not sure why...
Dial it back to 1400 and you should be good !
Thanks. That strangely seems to have solved my issues for now. 3850 h/s for just over 500w with the 1080 ti now.
Welcome to AMD world' nothing is static or clear here :p Rember finding that stupid cause made me so angr after countless times overdoing everything correctly and still no powersavings
Is Anyone using watercooled cards here ? Have you testes how far you can push the HBM now with latest drivers eliminating tha wall for it ? On stock or maybe even at 1.4v... ?. I am guessing 1300mhz is doable with water but cant wind a watercooled for a decent price...
I will dedicate one of my air cards for being a guinnea pig whats the actual max you can do with adequete cooling. Stock card could npt even do 950mhz. With 64 bios its doing 1100mhz easy. I have a huntch that 1.4v might give us 1300HBM on the better silicon.
