Why do you want to use such GPUs? They are mostly useless. Any GPU costs same as much as profit it brings. Try to search AMD RX470-580 with 8GB memory at least. Or may be 1060 with 6 GB.
In another way you can buy 3GB or 4GB GPUs, but you can`t mine the most profitable coins with them.

funny thing. I picked up a pair of AMD Firepro S9000 (6GB ECC RAM) passively cooled gpu's for $175 off of ebay. Popped one of them in to a test rig, fired up lolminer and off and running @ 23 MH/s. They do run hot currently, 74c. So I am redoing the thermal pads and paste on the second card. This card is the pro version of the HD 7950. But it was cheap, and I was interested to see if it would actually work. If anyone knows if I can control voltage and clock speed via parameter setting with lolminer, please post a link to the documentation.

Thanks,

Are you mining Ethereum or Ethereum Classic?
HD 79XX series hashrate dropped when increasing
Dag file, and so they were sold. Although these cards had 3GB of memory, except for the HD 7990.
These cards were very hot, if I'm not confusing anything, then they were heated up to 90 C. After 100 C, my farm turned off.

This is the professional version of the 7950 called the FirePro S9000. They are passively cooled and designed for high density servers and doing rendering/AI-ML type workload. They come with 6GB of ECC RAM as well, so I am mining Ethereum. The DAG generation is actually pretty darn fast around 3000 ms and one I have running has been rock solid at 23 Mh/s at 73-74c with a aftermarket mod from gpumod.com Here are some links to the card.

The biggest draw backs I have found is while 'lolminer' will work with the card, tweaking it seems to be hit or miss if the changes actually happen because the monitoring tools under linux are pretty limited. Oh and that it really does draw about 250w when running.

Update 4/22/2021 -- Complete redoing the thermal pad and paste on one card. It drop the temp 5c .. I have a universal mounting active cooler coming in. When I get that, I will test that. But for now a 5c drop works for me.

23MH per second for a 700$ gpu ? That's pure madness mate, not worth the money, even a 500$ worth rx580 8gb will give you 32MH per second, this is complete waste of money, it's always about the hashrate
