Lolliedieb
AMD HD 7950 was great GPU few years ago. I would replace it with some better GPU but situation on market is not good and I try to find how to mine with "Tahiti" card.
I run HiveOS and I can mine with lolminer on my HD 7950. It can mine ZELcash (EQ 125,4), about 12 H/s, it can run stable for days....
I tried to mine other coins but lolminer crashes when I try to mine coins with other algo. (HiveOS reboots PC after one or two minutes).
BTG & BTCZ (EQ 144,5) - cannot mine :-( AION (EQ 210,9) - cannot mine :-(
This is strange. HD7950 has 3GB of RAM, that is enough for BTG, BTCZ & AION but I cannot mine these, PC reboots. It looks like there is some bug in algo implementation EQ 144,5 and EQ 210,9 for HD7950... EQ 125,4 (ZEL) works good. I tried to mine with GMINER but that miner doesn't support such old card (it reports it doesn't have kernel for this chip). I have to use lolminer.
This is what I see in console of HiveOS when I try to mine AION:
HiveOS reports this: Kernel version: 5.4.80-hiveos AMD driver: OpenCL 20.40 GPU: R9 280 × 1
