Add more memory. In the Electronics Shop we have 64MB in our NT workstation systems. DIMMs are 168 pin configuration. Not every combination is available. There is a further complication.
Most computers have two to four slots to hold memory.
If you wanted to add an additional 16MB of memory to bring your system up to 32MB, and all your memory slots are full, you would need to remove your old memory and buy 32MB of new memory. We keep a large selection of memory in stock at the Electronics Shop. If we need to order memory, we can usually get it the next day. The memory that we use has a lifetime warranty from the vendor. Remember this is only a guess .
