Every Chines Clone Card above 32MB makes some trouble regarding my experience with them. They don't boot allways, etc. but do their job most of the time. I recommend to their users to switch to a "brand" card like MaxMemory if they have some spare money, because they work much better.
Slim PS2 SCPH-70004 (v13) w/ FMCB, 3x Sony 8MB, 1x MaxMemory 16MB (Backup card)
I'm not available for FMCB installation service until I can guarantee a processing time of a few days again, sorry.
