r9 290/390 give 29-30 mh/s while mining on Ubuntu. For a serious increase in performance, you have to use Ubuntu version no higher than 16.04 (with new Ubuntu kernels these cards have poor compatibility). You have to install driver version 17.40 and AMD SDK kit. Switching to Linux-like OS gives additional 10 mh/s (50%). There is a guide how to do it (in Russian): https://www.cryptoprofi.info/?p=3313. Ubuntu will be useful for mining on all old cards including R9 280, 290, 295 and 390.

I will give Ubuntu a try for these old cards. But how about rx 470 / rx 570? Will they also have higher hash rates with Ubuntu?

No, AMD has good drivers for RX cards for Windows 10.

The speed is good for cards that are a few years old now.These cards consume more energy than the newer ones and with the actual mining performance you don't get a lot of profit if any at all.

If you are mining to keep the rewards and to wait when the price will be even higher than it is now that is a good thing to do.

I have rx 570 issues - 26-28 mh/s. before that, used for mining r9 290x speed was around 20-22. the new maps give a good performance

We have 4 r9 280x are doing mhs 17.88 each and a normal 18.730 ?
This dual MINING eth + dcr

Total 72.833 mh / s

I have old r9 280x cards doing nothing in the storage room. Finding this thread, I don't want them laid to waste. If I use them to mine ETH, can they still get around those hashrates nowadays?

No they can not. If I remember correctly they only have 3gig of ram and eth now needs at least 4gig.
You can however mine things like ubiq, Ella etc tha have low dag but you have to have free or extremely cheap electricity.
Best bet, sell them for 40-50 bucks, but your coin of choice and wait for it to go up.

Thanks for the response bro. I will just instead mine those old cards with low dag coins since electricity is not a problem here.

This thread sure brings back memories. At first I was confused why are people trying to mine ETH with an R9 280X but then I checked the date.

Back in 2016 you could mine ETH at around 20MH/s however as the Epoch DAG grew it slowed down more and more. I think about a year ago when I last tried mining ETH, it ran at maybe 8MH/s and consumed maybe 200 Watts. So very unprofitable.

AMD never issued a fix for the DAG issue unlike the Polaris GPUs (RX 470/570) so many of them were just powered off and sold to gamers. The same issue is happening with the R9 290 which can still mine ETH due to its 4GB of memory but the DAG slowdown, makes its very unprofitable.

Basically like the above poster said, just sell for $40 and get an Rx 470.

For r9 280x, I would set overclock to 1100 and powertune to 20.

79xx and 280x are 384bit memory interface so memory speed has very little influence with ethereum

Tonga 380, 480 etc have 256bit interface and there memory need more speed to get more hashes/s

voltage 1.09v 4x 79xx

GPU 1030Mhz

speed per GPU 19.3Mh/s, GPU which is primary and has monitor connected does only 17.9Mh/s

That is very good speed. You might want to reduce the core frequency a little bit. The memory speed matters.
