Is KHX3700K2/1G using BH-5 chip??

I know for Kingston HyperX KHX3200K2/1G is using BH-5 chipset since it is K2 not AK2 right??
And I find there is HyperX KHX3700K2/1G without the A as well, does that mean they are using BH-5 chipset as well??

KHX3700 does not have Winbond BH-5 chips. No new memory is shipping consistantly, or at all, with Winbond BH-5 chips.

K2/AK2 dealt only with Kingston HyperX PC-3200.
