Specifications
The TI5TT is a high-performance, Pentium-powered PCI motherboard with an ATX form factor. It is highly flexible in CPU frequency, L2 cache type and size, and main memory type and size. The ATX form factor of the TI5TT allows easy access to main memory sockets and expansion by using full length add-in cards. The board supports Modem ring-on function that allows powering on from remote via an external modem connected to COM1 or COM2.
The main features are listed as follows:
Main Processor

Hardware Description
This chapter briefly describes each of the major features of the TI5TT motherboard. The layout of the board is shown in Figure 1, which shows the locations of the key components. The topics covered in this chapter are as follows:
The TI5TT is designed to take a Pentium Processor with a bus speed of 60 and 66MHz. Since the internal clock of the CPU can be multiples of 1.5, 2, 2.5, 3 and 3.5 of the bus clock, the CPU frequency can be 90, 100, 120, 133, 150, 166, 200 and 233MHz.
The onboard CPU voltage provides support for CPUs Vcore which require voltage other than 3.3V such as 2.8V, and/or power consumption higher than 10 watts. One example is a P6 based Over Drive.
3.2 L2 Cache Memory
The TI5TT supports P.B. (Pipelined Burst) Synchronous Cache. The P.B. Synchronous Cache boosts the system’s performance 10% higher than regular Asynchronous Cache.
3.3 Main Memory
The TI5TT provides two 64-bit memory banks, up to 256MB. Each bank consist of two SIMM sockets, SIMM1/SIMM2, and SIMM3/SIMM4. Both EDO and Page Mode DRAMs are supported. The size of the SIMMs can be 4MB, 8MB, 16MB, 32MB, and 64MB.
Each 64-bit memory bank can also be populated by using DIMM (Dual In-line Memory Module). The DIMM size can be 8MB, 16MB, 32MB, and 64MB. The DIMM types can be FPM, EDO or SDRAM (synchronous DRAM). SIMMs are not available in SDRAM.
The following should be noted when populating the SIMM sockets:
1. SIMM1/SIMM2, SIMM3/SIMM4, DIMM1 and DIMM2 bank can be populated first.
2. Each bank should consist of the same size SIMMs.
3. Each bank should consist of the same type SIMMs. For example, SIMM1 and SIMM2 are both be EDO or Page Mode.
