I was refering to all of the revisions from 1.3 to 1.7, and i said that are UTT, that means either BH UTT or CH UTT (i don't have detailed info on exactly wich revision uses BH and wich CH). This screenshot is taken with a pair of v1.4 sticks at 3.4V; i've also popped the hs' off them and they were Winbonds allright.

I've personally seen only v1.4, v1.5 and v1.7, and they were all Winbond chips; the rest is based on 2nd hand info. Also, it seems all the 3200C2PT 1.X and 2.X are Winbond, 3.X is Infineon, 4.X is Samsung and 5.1 & 6.1 is MosEl; Corsair is using different numbers for every chip manufacturer.
