TBR3 500 PIII RAM Upgrade
The TBR3 500 PIII was also known as the Performance 500. The Performance 500 was a series of desktop computers made by Gateway starting in 1999. These computers were equipped with Pentium III processors. This series is no longer available from Gateway. Gateway does not offer any support documentation for this series on its website. However, systems, parts, and upgrades for the Performance 500 are available from various online vendors.

The Performance 500 supported PC-100 SDRAM. The PC-100 SDRAM can still be purchased from online vendors to upgrade older systems.
Capacity
-
The TBR3 500 PIII came with 128 megabytes of PC-100. The Performance 500 had three motherboard sockets for DIMMs. The greatest amount of PC-100 that the computer could support was 384 MB, three modules of 128 MB each.
-
Densities
-
The PC-100 RAM comes in various densities. Density means the configuration of the black memory chips on the actual memory module. If a module consists of 128 MB, it may have eight memory chips of 16 MB each; or it may have sixteen chips of 8 MB each. The former would constitute a high density memory module, and the latter comprises a low density memory module. In general, low density modules cost more than high density ones. The Performance 500 did not require a specific density.
Size
-
The DIMMs for the TBR3 500 PIII had 168 pins. Pins are the gold stripes located at the base of the memory module. These pins are the mechanism that connects the module to the computer's motherboard. In order to fit into the motherboard socket and function properly with the system, the memory module must have the save number of pins.
Other Specifications
-
The memory modules for the Gateway Performance 500 did not have to be identical. You could install modules of differing capacities or densities. System performance could be altered only by a change in memory capacity. The modules must be non-ECC memory. Error correction code is typically used by server computers. The DIMMs must also be un-buffered or unregistered modules. The PC-100 DIMMs must be 3.3-volt DIMMs.
