Looks like the XMR fork is coming soon. About 3 weeks or so. And it doesn't look like Claymore will be updating his software to support the new algo.
Any miners out there that are stable for the AMD RX series and maybe the old Litecoin era GPUs like R9 280X/Radeon 7970 ?
XMR-STAK?
When I tried that program in the past, my speeds were much much slower than Claymore and if I added more threads it basically ended up in an instant freeze.
It seems to work better for newer GPUs but seems unstable for the older GPUs. Maybe will see if there is a newer version that is more stable.
As for now XMR-STAK 2.4.7 is a bit faster for Antilles GPU then the last Claymore that was compatible (9.7, now obsolete). But it really need fine-tuning and proper driver selection cause latest drivers for Antilles (15.7) do not report proper memory size. The problem was discussed in deep at XMR-STAK github
https://github.com/fireice-uk/xmr-stak/issues/472. In short you have to use 14.4 driver for optimal performance. Please note that it is impossible to use HD69xx and RX in a single system with optimal performance.
Do people still mine with the 69xx GPUs? I assumed since AMD drivers 15.7.1 was the last supported version that most algos unless it's the Claymore aren't supported anymore.
I had luck mining ETH with that beast when the DAG was less than 2GB. I think it hashed at 26MHs and pulled 350Watts for that 1 GPU.
Equihash would never work for that GPU and neither did the other algos.
I sure miss that GPU. Bought it off a guy who used to mine BTC with it. Then I mined LTC, then Darkcoin, then ETH and last algo was XMR.
It ran at 100C for 24/7 for years and never had any issues. Redoing thermal paste did nothing.
Still have a bunch of the cards, still working without any problems. Due to high power consumption (I managed to stay within 250W for Monero7 and do not allow more then 85C for core) I have to run them only in night when we have special (50% reduction) electricity tariffs so it is surely not the best choice for now. I have better luck redoing termal paste - usually 10 degrees core temp reduction :-). When Claymore drop support for them I seek for alternative and with help of XMR-STAK community we found a way to work around the bag in 15.7 AMD drivers that prevented decent performance for HD6xxx cards. Going to use them to heat my garage in winter - no profit but no expence also :-)
