Title: [WTS] 3 USED 7950s (2 MSI, 1 Powercolor) & 2 powered PCI-e risers - 2mhash
Post by: twoturtles on April 09, 2014, 05:18:02 AM
Heya folks,

     In light of recent events (I was scammed out of 2.5 BTC by DarwinNexus) I'm forced to sell my GPUs.  I always kept them between 73-75 degrees or so.  There's no warranty due to me modifying them a little.  The reason for modification, was that after a lot of testing I found that removing the heat shroud and keeping it off along with the proper airflow+exhaust, these could be kept cool at 2mhash.  I also cleaned and reapplied thermal paste every month give or take.  If you're interested, I could clean them again and re-apply thermal paste before shipping.  I'll accept offers, so feel free to make them.  At the time I bought them I paid roughly $275 each.  0 hardware errors and mined with them 24/7 for about a year until now.  Below is a picture of them with the risers.  The dualminer USB stick honestly I bought about 3 weeks ago maybe and can't find software that'll work with it.  I have no idea if it works or not.  Feel free to contact me with any questions. =)

Why is there no cooling on the VRM's?

As far as cooling, I spent over a week and a half figuring out the best way to do it at the speeds I was having them hash at.  Put a good cool air source in front, a good exhaust fan in the back and you're as good as gold.

I would need proof they're real and handle this with escrow only but that's an interesting deal

I could come up with receipts showing they come from reputable refinery/mints, but the only real way to know is to hold one, get used to how it feels, sounds.. tastes.. It's not like gold where there's much to be gained by faking it.  Unless it was some kinda 'Franklin Mint' thing.. or a copy of a famous numismatic coin. Id stay away from any of that noise anyhow.  

Trust is earned, as well as lent. Eventually.
I'm in no hurry to part with Silver, but if you covered the cost of an intermediary shipper, Id consider that.
I suppose this persons going to benchmark/test them video cards..
I don't want to git no worn out Chinese knock offs!!  =p

I got me a single gridseed to hash my fav. meme/shitcoin.
It'll do till I need something to build/mine a test creation.
