In terms of reaching your ROI back the 7950s are good with an average of 17MH/s per gpu it beats its power consumption with its mined cryptocurrency. Its hard to find a new one, also be careful when looking for a refurbished one. Test it out first before buying it.

The power consumption of the 7950 is too high. If you pay $0.2 /kWh, you will not ROI due to the increase in difficulty.

If that's true why do people still prefer the 7950s rather than the R9 280X? It's even hard to find a new one. Your best bet is to find a refurbished model in the market. Also from what I heard 7950s ran quiter than the other models.

hello, i need help, how i can undervolt my amd rig card?? i have one r9 290x 8gb, one r9 380 2 gb and one r7 370 2gb...

where a find good modded bios for flashing it? or where i can find good support for guide me to flash it?

thanks for help me

If you use the Windows, you can use the MSI afterburner and the Sapphire Trixx. Both are good, the former is more popular.

thanks, but what are the best setting for mining eth?

so it seems that the new 470 is better than the 480? same bus but less consumption

I definitely believe that. 470 is gonna be much better than 480 for GPU mining, with less than 50 watts of power consumption. 480 hasn't proved much to be too good for mining, but I'm pretty positive for the 470 and would definitely wait for it to arrive here at my place.

It depends on the memory frequency of the 470, if it is the same as that of the 480, then it is good for mining.

+1 for stay away chinese usb riser on ebay. I bought 5 and more than 50% of them are not working... Angry

I had the same problem in the past, Amazon is actually much better since you can read reviews. Ebay is more of a gamble.
Gpushack which made ethos sells risers, I never puchased them but I'd trust them more than chinese sellers on Ebay

There are roughly 150'000 Gpu's mining ethereum at the moment.

If the hash rate increases like it did not in the past, in 4 months, there will be 600,000 GPUs to do the hashing.

At the current rate of rise, in 4 months, most miners will be not profitable. So most of them are confident the price will rise.

same old, same old... The litecoin boom (and bitcoin obviously) followed the same pattern, people notice it is still profitable to mine, lots of people join, profit naturally drops. Only thing I see is different now is that profits where a lot higher then and dropped faster, now profitable mining lasted surprisingly long but profit was a lot lower also. Tells me something about what will come in the next wave, a year or two from now, less profit, less fluctuation. Any thoughts? Am I perhaps way out there in my prediction? Cheesy

I think you're dead on. Also this time we KNOW that mining will end when they attempt to move to PoS which has actually kept the difficulty from rising faster IMO. The bust is going to be ugly, lots of cheap GPU's for gamers is my prediction.

There is no best GPU for mining, only altcoin with enough market cap that is mined by GPU in decent rate, atm that is ethereum which hold at least ~70% of GPU mining altcoins, if that fall profitability in instant would go to zero

and depending what algo for mining that coin use you chose the GPU

I think the Ethereum holds at least 80% of all the GPU mining power. It will soon by 90% in the near future.

It depends on what is the limiting factor. If the memory bus is very fast, you need the 480, if it is slow, you only need 470.

From the information from early miners of the 480 RX, the memory is the limiting factor, the core frequeny does not matter much.

Will have to check GPU-Z to validate.

Also I got a 390 and 390X, sadly both volt locked. So my -100mv 290X can almost reach a 390 stock.
Windows 10, latest AMD drivers, getting 29-31MH, 33MH with extreme overclocking.
390X runs a bit cooler and can crank out higher engine OC, but I need to upgrade my PSU to make things safe to test long term.

I have not messed with memory clocks, as I'm happy with those speeds, but curious if anyone else has feedback.

You can use the HawaiiBiosReader to modify the voltage to be lower than the stock. It will save you lots of energy.
