How do you know if a 512Mb RAM module is accepted? I have looked around the 4100+'s documentation and gone through the different screens on my unit and cannot see anywhere where it tells you how much RAM you have... just CPU usage.
I want to start using several different modules with mine in addition to Firefly: NFSd, Rsync, SSH, ML Donkey, the FTPaccess etc.. and I'm not wanting to compromise performance.
I did some research as I am planning to upgrade to 1GB of RAM myself If you are shopping for a 512MB or 1GB upgrade for your N4100pro and want the best performance make sure it meets these specifications:
+ DDR-400 aka PC-3200 *NOT DDR2-400 PC2-3200 or higher* + DDR-333 PC-2700 and DDR-266 PC-2100 should work, but are slower + 200 Pin SODIMM (laptop memory) *NOT 168, 184 or 240 pin DIMM (desktop)* + Voltage 2.5V or 2.6V *NOT 1.8V* + LOW Densty 64Mx8 *NOT the uncommon high density 128Mx4*
Note that anything marked higher than 3200 (4200/5300/8500) or 400 (533/667/800/1066) is DDR2 and will NOT work, in fact it won't even fit in the slot, they are NOT interchangeable. 3200 is available in both DDR and DDR2 however DDR2 should be marked PC2-3200, is much more readily available, and generally substantially less expensive, hence it would be easy to buy the wrong thing.

Thank Thecus for NOT supplying enough RAM as shipped, nor the information needed to purchase a proper upgrade, nor support for NAS RAM upgrades in general. If there is one thing I could say negative about Thecus from reading the forums, is that they do NOT support their products, and thus their customers, very well.
