Hello guys, I have a problem with one of my rx 470.
It's a MSI gaming 4gb, used to make ETH only 28,5 Mh/s with :
1500 straps, -60mV core, 1150 core, 2000 mem, claymore 9.4, crimson 16.9.2
Now, after trying ETH +SCI (that happened about a the same time that windows 10 downgraded the drivers to 16.6), it was doing 18 MH/s ETH + 560 SC, which i first thought was normal.
Now, i'm getting more and more gpu Watchdog hang problem. The miner restart the GPU works fine for 1 to 6 hours then hang again.
Played with -dcri and managed to get 25 / 400 once, but can't achieve that again. (and the hanging problem didn't disapear)
increased core voltage and speed, hang problem still there after about 1 hour of mining.
I went back to ETH only to see if the problem comes from the dual mining, but now the card mine at only 25 MH/s.
Uninstalled MSI afterburner, uninstalled drivers with DDU, installed 17.4.3 patched with atikmdag, reinstalled afterburner = same hashing speed.
Uninstalled 17.4.3 and reinstalled 16.9.2 = still 25 MH/s
Changed bios to 1750 straps, nothing changed.
System :
-Windows 10
-8 gb ram
-750W bronze corsair PSU
-also mining with a 7950 on another miner, never had a problem with this one.
All my other rigs with rx 470 are running stable with ETH for weeks (except one that the fan randomly hit 100% until I reboot, but that's another story less urgent)
Anyone has an idea?
(Edit : very stable 20 MH/s ETH only -18mV core 1050 MHz, 1750 mem , no hardware errors in 3.5 hours... but that's very low, my 1 fan XFX is doing 24.5 MH/s with the same settings)
