DDR2 Full Specs

[moonsond]

Hi everyone
got this mem recently, it was quite a cheap. OCZ DDR2 PC2-5400 Gold GX XTC Dual Channel 2 GB kit, nominal is 1.8/667/4-4-4-12. Currently stable on 3-3-3-9 with 2.0 and 1.9v, not really sure about stability @ 1.8v, no real testing was run on this voltage, but rig is able to start win then definitely
Any ideas of what the chips are there? Google, http://ramlist.ath.cx/ddr2/ - doesn't seem to know what the chips are.. I can't check myself, because i'm not sure that i'll be able to get heatspreader back so it wont be noticeable that i removed it... but chips are pretty small(NOT BT-3 definitely), 10*11 mm or about so, longer side perpendicular to mobo.
And last, is this mem a real crap? will I be able to reach 450 fsb 1:1 with it on a P5B Dlx? Or i'd better begin thinking of changing it for something better?
Thnx for any answers.
