Low hashrate on RX 470

[ripper101]

So I am pretty new to mining and it is something I slowly wanted to get into to learn/mess around. I found some cheap mining rx 470s off eBay for $70. They came without the cooling shroud and were pretty heavily used. Anyways when I hooked them up with a PCI extender and switched them over to compute mode in the AMD drivers I ran them on Pheonix miner for ETH. Currently I am only getting 0.8 MH/s on these cards and I cannot really find the issue. I attempted to switch the BIOS but I am not sure what I am doing and the timing numbers do not match the videos I've watched. On top of that I am not really sure what the subvendor for the card is to switch the BIOS. It's obviously a card designed for mining as it only has one HDMI port. If anyone has any ideas to fix this I'd appreciate any help

Yeah you're not going to be able to mine ETH with a 4GB card, due to the DAG file being much bigger now.

it shouldnt be that low, but it will be lower tyhan when the cards were new b/c of the fact that its a 4gb model. You need more than that for pheonic miner now iirc.

my 480 4gb was getting over 10x that, it will be lower, but not that low.

Well the DAG file needed for ETH mining has grown bigger than 4GB now, so it's not gonna perform the best.

 

When were you mining and getting that performance?

Check out this article from Jan. 21 explaining what you need to do:

like a week ago. i mean, 9-10mh/s isnt the 21mh/s that the thing would've gotten when it was new, but its not .9mh/s

Yeah that's pretty strange then

Huh. I was using NBminer, but here (took just now with gaming mode and mc running in the backround)

are 8GB cards still feasible for mining then?

Yeah 8GB should work better, but you could still run the 4GB in zombie mode.

I just probably won't be getting 20MH/s right? Can pheonix miner do zombie mode?

Yeah you won't get 20M/h, and yeah pheonix mine does support it.
