EA Games & GH015 Model Board problems

[E4x250]

Hi there !
I got a PS2 console and it has been modified with a Neo 2.2 chip & Action Replay 2. Copies of games i've made all work fine doing the swap trick except for EA Games. I've tried Gradius 3&4 and X-Squad but they won't start up in my PS2. I've tried different burning Methods (eg: CloneCD, Cdrwin & patch) but none of all the copies i've made worked
:-(
The installation pics & instructions i've found on the internet for the GH-015 board with Neo chip said that the chip has only be soldered to 5 points (instead of 8 as with older boards)as EA games swaapping is not possible with this board.
Is that true ?
Where can I find additional pics or instructions ?
Does anyone know a trick how to start EA Games with the GH015 Board ?

Thankx
