Low hashrate Msi HD 7990, Eth mining

Getting 20H/s on nicehashminer maybe it's not fully tested and config isn't set up properly but 150 is unreal (possible with some cracked bios or something maybe) (exp 47mhs with little overclock, after watercooling we can go for more overclock and maybe 50mhs+)

I found that mining EXP results in a faster speed however you usually make less with the coin so in the end it balances it out. Just a waste of electricity

Don't worry we have free limited electricity so that's not a problem Grin

You should use the Claymore miner, it is quite fast in the old cards like the 7970, 7990 or 280x.

It is more profitable to mine the ZEC for those old cards. They are very slow in the mining of the Ethereum.

Yes he should get at least 150H/s with ZEC.

That is right. It is better to mine the ZCash now with the 7990 or old cards. They are more efficient there.

You should mine expanse. Smaller dag buffer. And get 40+ on the 7990

Thanks man, we got 45mhs right now (pool showing 50) These are great stats for now, do you change config on your exp miner like local/global work?

These days 16 MH/s per core is normal for ETH

Thanks, I was worried that the settings aren't set up properly, so it's because of dag right?

Hello everybody, recently we managed to get radeon msi hd 7990, we were expexting to get at least 37mhs on eth mining some sources provide also 43+ mhs, firstly we tried latest drivers and went through different miners nicehash, claymore... we get around 28mhs which was disgusting (os - win10 pro) , later we tried catalyst 15.12 which wasn't working and the card wasn't recognized as opencl device, so we installed crismon 16.1.1 , and tried ethminer from dwarfpool, we set a little overclock and also local work in config - we got max 32.5 and stable 31.5 now which is better according to this card should be something like 2x hd 7970 which gives at least 2x 17-20 mhs... (maybe is because of big dag file...! , but now I discovered that stats on pool doesn't match the miner stats, we are getting 32mhs in miner and 36 - 45mhs in the pool statistics, I don't understand - it's calculated on how many shares we have submited or how? you can see it in these photos

and

at least maybe the eth proxy can help to increase the share rate, but it's quite hard to set it up, is there some basic guide?

Thanks
