  • Slow cache without "dirty bit" chip installed

This motherboard uses a chipset that does not support a 7+1 bit tag system for cache, and requires a dedicated SRAM chip for dirty bit tracking. If this chip is not installed, all blocks in cache will always be marked as dirty and main memory latency will be significantly higher.
