It was only the wind.
Don't have time any longer for mining -- I was averaging 1,880kh/s using these GPUs.  Make me an offer in LTC or BTC and I will ship to anywhere in US.  Not looking to scam or get scammed, so we'll exchange info, skype, phone, tracking info and all that.  

Would prefer offers via PM (easier to find).  

You're doing it wrong. You should have been averaging a little over 2MH/s.


It sounds like you are really underclocking them,. How much ram do you have? From my personal experience of running 3 different brands of 7950s I've found they all run at a different hashing speed. My Gigabytes are the quickest at about 650KH/s whereas my sapphires I can't seem to get them above 580KH/s. My VisionTeks are typically 600-610KH/s. I'm still tuning the VisionTeks. I'm pretty sure I can get more out of them.

I don't know what I'm doing wrong with the sapphires. I have 16GB RAM on all the boards. I didn't struggle with 8GB of ram on the board, but it did seem to help when I went to 16. 6GB was a no go for 4xSapphires.


My Sapphire 7950 pulls 650+kh/s.

Greetings.

Perhaps 1,880 MHash/s and not 1,880kh/s, am I right?

Good luck with the selling.


1,880 KH/s mining scrypt-based coins like LTC.

Are ฿itcoins Radioactive?
