Problems with non-solder mod chip

[BigLos]

I have a v5 ps2, bought the non-solder mod chip from lik-sang and, as far as I can tell, it's installed right (it's pretty simple) but the problem is...none of the ps2 backups will play. I've tried 4 different games and the closest i came was nfl gameday 2002 which froze when the 989sports screen came up. This is getting a little frustrating. Can anyone help with this !? plz...
