Is KHX3200K2/1G using Winbond BH-5?

Is this ram uses Winbond BH-5 chipset FOR SURE??
Kingston HyperX 512MB x2 KHX3200K2/1G
I heard alot of people say they are, but I need to confirm are all of them use BH-5 or just some of them?
Thx.

Yes, the 1GB kits of KHX3200 Non-A use BH5 chips. As far as I know, there are no 3200 Non-A modules out there that contain anything other than BH5. My set of KHX3200K2/1G was in fact BH5, and it is doing quite well for the moment. I just need more VDimm.
