ReadyNAS 426 memory upgrade (it is possible!)

Hi,

I just succesfully added a extra dim in my RN426 readynas. I have opend the black cover and remove the 4 black screws from the metal frame and you can get to the mainboard :) You can slide this side open. I saw 4 memory slots. I have added the same memory that was already in it from Transcend the TS512MLH64V1H. I paid 39,- euro's in Holland but you can get it for arround 26,- here also.

/home/admin# dmidecode -t 17
# dmidecode 2.12
SMBIOS 3.0 present.
# SMBIOS implementations newer than version 2.8 are not
# fully supported by this version of dmidecode.
