Which OCZ Platinum Rev. 2?

I decided these sticks would be the best price/performance for my below rig, as the hyper-x isn't letting me push very far.
So I have a guy who is selling them for ~$140 per pair and he has two pairs. Here's a quote from him:

One pair is from January 2005 and the other from June 2005. They both have this info on the stickers:

PC3200
512 MB EL Dual CH
Platnium Rev 2
2-2-2-5
P/N: OCZ4001024ELDCPER2-K

However, the June 2005 has a slightly different heatspreader on it, a little thicker.

Suma says in his chip list:

-- DDR PC3200 Platinium Edition rev2 (2-2-2-6)
Samsung 4ns TCCD

But aren't the new chips tcc5? I.e. the june 2005 one? Is there any way to tell? By my understanding, this sticks will do near ddr600 at some pretty tight settings. Anyone care to chime in? Thanks!

TCC5 I believe has a small v1.1 on the sticker.

ahh. Much appreciated. Will ask the seller!
