I bought these when I wanted to make a few rigs, but I ended up recycling old PC's so that never happened.
Two are from Micron.
One is from Samsung.
They are all 1 GB DDR3 PC-8500
I ran Memtest86+ and no errors were found after several passes. Mixing brands is not an issue.
1.65 BTC shipped for all 3 GB or I'm willing to sell individually for .5 BTC each + .35 BTC for shipping
paypal is also an option and I would be willing to ship outside the United States; however, shipping may cost more.
PM me if you're interested
