I recieved both of my 165s that I ordered from Monarch about a month and a half ago Both are CCBBE 0610 DPMWs. I threw one in my Venus rig and the other in the expert rig. They are both priming away at about 6 hours right now, one at 352x9 and the other at 349x9. By all means the best opterons I have seen in my hands
