This is crazy. I ordered fifteen (15) cards from Newegg.com for $249.99/ea and that was in December!. The crappy part is how I had to order them in groups of three. Wait 48hrs. Order three more, etc. I did the BIOS mod and I'm getting 29.8 MH/s per card average for the Samsungs, 28.7 Hynix, and 24.66 with the crappy Elpida memory. Thank God that almost all were Samsung!
That's why I say the Nitro+ 8GB are the most sought after. I have 2 of them and they are both getting 31MH/s after BIOS mods with zero memory errors in HWInfo.
