Please identify my chip...

[Big GJK #11]

Hi all,

Almost 3 years ago now I purchased a messiah 2 pro v1.33 chip from charlie_ps2 and had it installed by someone here in holland on my us v7, but i keep getting strange rsod errors for some games. For instance mgs 3 and the new subsistence. They boot fine and everything, but when I choose the online function, this happens:
screen goes black,
disc reads a little,
drive spins faster and then slower,
i hear a "click" from my hd,
the "no-data" screen appears followed by..
RSOD!

Up until know I tried a few things. I read that a rsod alsoo could be caused by the tray hanging a bit to the side. As my tray also had this, i tried to lift it a little, but no luck. I also read that it could be a laser problem, but i personally dont think this is the case, cause all my other games work flawlessly. Then I decided to open up my ps2 system and check the original messiah 2 v7 diagrams and noticed that the solder points were very different! Could this indicate this is a clone chip? I googled for some pictures of the chip and some "clones" looked the same to my chip but my chip has written "datel" on it and on the picture it was "scenix".
Im clueless as what to do next, so if anyone can help please do so!

Anyway, heres a picture of the chip:
