Topic: Worth buying cheap 6950s for mining 2017? (Read 287 times)
You can also mine ETH type of coins like EXP or MUSIC or whatever other coins are out there if you got the 2GB model. Speed is like 13mh/s
I get ~515 H/s @ 105 W on XMR with a Powercolor HD 7850 and ~195 H/s on ZEC for ~140 W with the AMD blockchain drivers.
Woa! Thats nice! My cards Gigabyte are clocked 975MHz core. And 1200MHz memory (I think)
One of the cards is very easy to overclock but the other one have worse ASIC Quality and don't like clocking of the memory at all.
I think I could get both cards Core up to 1200MHz at some point before. On the other hand they run really cool now 40-46C.
So you raised the core to 1.2V and GPU to 1225MHz and Memory 1500MHz -10% powerlimit

Drivers for the 6xxx series isn't an issue - 15.12 works FINE on them.
The TERRASCALE is the issue - a lot of current miners are GCN specific and won't work at all with older cards.
78xx cards are GCN - not comparable for mining.
IMO avoid the bloody Relive drivers unless you HAVE to use them - horrible bloatware that do not offer ANY performance improvement (except in narrow cases using the "Blockchain" drivers).

HD 6XXX is a TeraScale 3 GPU, which is Pre GCN, so you can't use the latest Crimson Relive drivers. Finding miners that work will be a challenge. If you're going to go old school, at least get a HD 7XXX series. HD 7850 get ~195 H/s on ZEC and 500 H/s on XMR with the current series of drivers and miners.
Actually I have 2x7850 today. The 7850 does 150H/s equi and 400H/s XMR and they run really cool.
The 6950 modded with 6970 bios does 360h/s XMR at 140W (possibly even lower)
You dont want to buy them.
Also you dont want to Vega for mining, they are terrible.

Hello
I can buy some 6950 really cheap. I know they perform decent in NeoScrypt and Cryptonight.
Don't know if there is other algorithms that could be interesting?
I was thinking of buying 4-5 cards and use for mining.
Electricity is cheap where I live but these cards consume quite much power since they are old.
What do you think?
If you think it is a bad idea I will probably wait for Vega 32 (if fair priced) or Volta/Navi.
