The IBM PC Server 500s support a maximum of 256MB of ECC memory or 64MB parity memory. All supported system memory is addressable through direct memory access (DMA). Maximum system memory can be achieved in all models by using 32MB ECC SIMMs. The IBM PC Server 500s support 4MB, 8MB, 16MB, and 32MB ECC memory SIMMs (70ns). All memory SIMMs must be installed in matched pairs.

High-performance BIOS uses 128KB of system memory and an additional 256KB is reserved for installing options that may require additional memory for BIOS shadowing.

Addtional specifications:
The PC Server 500 and Server 95 systems use the same base planar which includes the Real Time Clock. Its accuracy is +/- 3.9 second/day (or +/- 23.7 minute/year).

The PC Server 500 and Server 95 systems use the same base planar which includes the Real Time Clock. Its accuracy is +/- 3.9 second/day (or +/- 23.7 minute/year).

The speed of the 95/95A and PC Server 500 L2 cache is determined by the processor complex. The Processor Complex used on these machines does not use stand alone SRAMs. It uses Intel C5C'/C8C' cache chip set. It is a modification of the chip set used for our Pentium based Mod 95, to run at 3.3V with a P54 CPU. The C8C' chip is a data chip, that has the sram, as well as quite a bit of data buffers and some logic.

Because it does not used standalone SRAMs you cannot quote a typical RAM speed (such as the PC Server 300 which uses 15ns SRAMs). You should quote a cache hit speed which is much more representative of the actual performance you get. So, the L2 Cache size on a 95 or 500 is 256KB - write-back policy, 0 - 1 wait state. Cache is matched to processor speed i.e. 60MHz with the Pentium 90/60, and given a 90% cache hit speed is 33.3ns and 0 wait state.

If this machine did use standard SRAMs, an access speed of around 10ns would be required to run in 0 wait states. 25ns access sram is used for machines based upon Intel 486's running at 33MHz external frequency, such as a 486DX-33 or a 486DX2-66.
