I think I found something: your new RAM is single side (SS), while in the official memory list there are only double side (DS) 4GB compatible DIMMs. Usually the SS DIMMs has memory chips only on one side, while the DS DIMMs has memory chips on both sides of the DIMM :

EDIT: it seems I was not right, because I found out that your Transcend is apparently a DS DIMM... In the pictures it has 16 chips, so 16x256MB = 4GB, but it the motherboard's manual (page 1=13) it says it cannot support DIMMs with 256 MB chips or less, so for 4 GB you must have a DIMM with only 8 memory chips on it (8 x 512 MB). The best solution is to test several different DIMMs from different manufacturers, so a visit to a PC repair shop.
