System Board and Memory Optimizations (Windows 95/98/Me) Popular

These settings allow you to optimize the AGP and PCI buses along with the system memory by reducing the number of wait states (idle time).

This tweak can be easily applied using WinGuides Tweak Manager.

Open your registry and find the key below.

To decrease the PCI bus wait states create a new DWORD value called "PCIConcur" and set it to "1".

To decrease the AGP bus wait states create a new DWORD value called "AGPConcur" and set it to "1".

To decrease the DRAM memory wait states create a new DWORD value called "FastDRAM" and set it to "1".

Restart Windows for the change to take effect.

Note: Wait states are periods when the CPU or bus remain idle to allow other system components to catch-up. Therefore decreasing the wait states reduces the amount of time the CPU or bus stays idle.
