Hello all,

I have a few questions.

First, I have a Sapphire r9 290x trix OC. I get about 30MH's with it using it to mine ETC. The fans are going bad on it. I bought it on Newegg in 2014 and have the replacement warranty on it. Newegg warranty wants me to send it to them and send me a Newegg credit for it for $319. I could take that money and then get a RX 580 4gb card(is it worth while to add a bit to the credit and get an 8gb version). Would you do that or would you just replace the fans yourself?

Second, I also have 2 XFX HD 7950 DD cards. I have one in my rig I put in last night and it is only gettin 10.8 MH's. It is at stock speeds. I tried OC ing it with Wattsman and I can get it up to 12.8 MH but that is all. I am using Claymore's Miner v10.

Third question, Using Claymores Miner, how do you change the intensity levels of each card separately? Card 0 is the 290x and card 1 is the 7950.

This is what my config file reads:

EthDcrMiner64.exe -ethi 10,13 -epool etc-us-east1.nanopool.org:19999 -ewal 0x4caba6b3cef*********5d20ad7.**/*********@****.com  -epsw x

I have also tried EthDcrMiner64.exe -epool etc-us-east1.nanopool.org:19999 -ewal 0x4caba6b3cef*********5d20ad7.**/*********@*****.com  -epsw x -ethi 10,13


Nothing changed in hash rate when I added the -ethi 10,13

Please help as I am reading that I should be getting 18 to 20 with the XFX 7950.

Thank you in advance for help and thanx for taking the time to read this.
