The maximum memory capacity of this Shenzhou machine is 4GB. However, it should be noted that this Shenzhou machine uses the same mold as the previous F233T and the newly released F320T.However, this model has a disadvantage that it has only one memory slot, so it cannot be directly upgraded to 2GB memory.According to the disassembly test results, many users have tried to disassemble these three models and confirmed this fact.If you want to upgrade your memory to 2GB, please purchase a new 2GB memory and replace the original 1GB memory.
