install one at a time
We sell single banked simms. Double banked simms may also be used, but you can only install one double banked module and nothing else.
The K2600 can use 5 volt or 3.3 volt SIMMs. If 3.3 volt SIMMs are installed, a jumper must be moved. (This is documented on the inside of the panel which is removed in order to install the SIMMs.)
