Confirmed, I have 2x PS3's with Jailbroken Firmware on them and neither could even get close to 20 Mhash/s. The GPU's just aren't set up for mining at all. Might also pay to note if your PS3 isn't on custom firmware now, and you've been online since version 3.55 (so online within the last 2 odd years), then you have no way to go to CFW without opening it up and soldering in a hardware mod - not easy for most.
Vircurex probably safer, but BTC-E seems a lot more liquid. I seem to get in, make my trade, and get the coins out with BTC-E and never have issues...many claim to. It's run by Russians.
Hopped onto this new coin that came out about 12 hours ago called 'CHNCoin'. One guess as to what it stands for.... lol (China Coin). It's another Litecoin fork, but can't help but feel it will have merit amongst the Chinese alt coin community and wider crypto audience. Not to mention two of the larger alt coin exchanges Vircurex and Bter are both Chinese operated. Might be nothing, but we'll see.
Dammit! I forgot to leave my PC at home on today so I can't remote in to start on it. What mining pool are you using? Thanks.
There's only two P2Pools running at the moment, very flaky. Currently using altcoin.pw:1024 - just use your CHNCoin wallet address as your username and anything as a password. I ended up mining about 7000 of them overnight which I promptly sold 6500 of them for 75 Litecoins this morning whilst everyone is in mania phase. So that's 2.5 BTC for 8 hours mining. I am happy with that much return Now I am just mining them some more in case price rises.
I had a bit of a stab at it overnight, but like a lot of others found, all orphans (22 blocks found by client, none accepted by wallet).
One guy I chatted to must have aced the setup. He jumped on it with the same hashing power as I do when it was first released and ended up with 300,000 coins. Needless to say, he's rolling in about $8,000 now.
okay had it with ozcoin, they've shutdown their litecoin mining pool but my miners are still connected and hashing, it's just not registering -_- too much instability, i'll leave them as a backup from now on. I tried coinotron but I had a lot of instability with them as well? any litecoin pool suggestions?
I'm running --intensity 19 --thread-concurrency 24000 --worksize 256 -g 1 --auto-fan --auto-gpu --gpu-fan 25-80 --gpu-engine 600-1000 for the card. I had to read a few things before I figured out what thread concurrency should be (64 x memory bandwidth and then decrease to suit) the 7950 has a 384bit bus so thread concurrency starts at 64*384 then add or subtract to tune it
that gets me 605 kh/s There are 2 7950's though, I've got the gv-r795wf3-3gd revision 2 model I also updated the firmware (which you shouldn't need to do)
I have 2 gigabyte 7950s running @ 1200/1500 giving me 720kh/s. They draw 345W each though because they're voltage locked @ 1.25V. I tried flashing older bios to lower the voltage but it wouldn't post and i had to flash back. The first card was using 345W and I though adding the second might add another 250-300W but it doubled exactly to 690W. Clearly my motherboard and CPU use only the difference in efficiency. the only things i have in my config file is "intensity" : "20", "api-port" : "4028", "gpu-fan" : "85", "gpu-platform" : "0", "gpu-threads" : "1", "gpu-engine" : "1200", "gpu-memclock" : "1500", "failover-only" : true This is running on BAMT (linux) using cgminer 2.11.4 One important thing if building a system is getting a good PSU. The one I have is 80PLUS gold so the min efficiency (from memory) is 88%@20% load. When I first got my 7950 and PSU I tested the card with a cheap PSU and it was using 100W more. As for long term profitability, I expect that like any other investment I've made it will end in a loss, but at least this interests me as a nerd.
