I have a DS3 v3.3 board and its perfect! No funny reboots, no RAM killing its completely stable
I havent played with any other conroe boards so I cant compare it to anything but in my opinion its a cracking little board for the money!
Vdroop would be my only concern but after attempting the Vdroop mod on my version 1 board and killing it I dont fancy attacking this one with a soldering iron just yet lol!
