He is mining LTC not BTC.

Yeah I can't believe the difference in hash rates between the green and red team. I think it is interesting that the 680 and the 7970 trade blows across lots of games but the difference in hashing is unbelievable. I luckily was never a fan of the green team anyway and have always used AMD. I think my first AMD card was a 9200 Pro lol.

I personally use LastPass but my password for LastPass is a 20 character random pass with symbols included so I highly doubt it will be getting cracked very easily.

Yes Balthazar is correct, I am getting 1500 Kh/s with the 6950 in my wife's computer, 6970 & 6950 in mine and a 4890 in the kids computer. I am hoping to build a dedicated miner with 4 7970s sometime soon.

I don't know why I didn't tell you but the video card I am talking about is a 6950 and it does 432 Kh/s at the settings in my previous post. I can't really tell you if 7950s are the best because I don't own one. It does seem from all the reading I do that at least 80% of the new rigs being built seem to include the 7970. I personally would like to build a rig with the Gigabyte 990FXA-UD7 and 4 x Msi or Sapphire reference 7970s so I don't have to use any riser cables.

My HAF 922 has 3 6970s and they all run around 80 - 85C. I think it is because I have a 200mm fan blowing air in the side of the case, basically right on the cards and then I have a 200mm fan that exhausts the hot air out of the top of the case. Maybe you could modify your case to put some 200mm fans in? Hope this helps.

I am using the testing branch on p2pool with my 3 computers doing 1500 Kh/s and it is working fine. All computers have Windows 7 x64.

They did used to be unlocked so not sure. I can tell you that voltage unlocked is nice, I mine LTC which is picky about memory speed but @ 885 core and 1375 memory I get the best hash rates and was able to lower my voltage from 1175 to 1145 which actually made like an 8C difference on temps.

The Gigabytes are indeed voltage locked now.

These are the 7950s I have found that still seem to have the voltage unlocked.

I do understand what your saying but I can mine at an 18 intensity on my 6970s and they don't break 80C, I suppose if a fan suddenly died you would be totally screwed but most of the cards I have had started clicking or something to let you know the fan was going bad. I am wondering if a lot of people don't care and just run their cards at 100C all the time or something.

   I was looking at a thread in the marketplace where the poster wants to buy cards that are not working or have problems etc.


 It has page after page of people with fried cards, this makes me wonder if mining does some damage to them that gaming does not? If anyone has an idea about this please discuss because I am wanting to build a rig for LTC or NVC but if I am gonna be frying cards all the time it may be more expensive than I thought. Thanks in advance!

Hello everyone! I have actually been into mining for a little over a year but I started with litecoin. I wanted to be able to post here and ask questions if needed. I figured it is likely I will run into some problems that the members here will easily help with. Since most of the forks of bitcoin is so similar to it I guess this is the best place for a lot of those questions. Anyway sorry for rambling but nice to be here and hope I can offer something to this community.
