Risc PC - VRAM

The amount of VRAM determines the maximum resolution and number of colours. It has its own dedicated slot on the Risc PC Mainboard. If it is single sided then it is only 1 Mb if it is double sided then its 2 Mb.

Risc PC - Power Supply (PSU)

If your planning to run extra hard drives the larger power supply is useful. I had issue's when running 2 hard disks and a CD drive with the low power supply.

Low Power Supply (0197,110)

5V = 7.9A, 12V = 2.05A RISC PC - Power Supply - Low Power

High Power Supply (0197,010)

5V = 11A, 12V = 3.6A RISC PC - Power Supply - High Power

Risc PC - Overclocking StrongARM

Note: The StrongArms speed is written on the processor (not really sure if it is any use tho!) RISC PC - StrongARM CPU Closeup Note: The StrongArm is by default locked by tracks on the back of the board forcing two switches to be on. To overclock it these tracks must be cut. Careful not to cut other tracks and tracks deeper in the board ! RISC PC - StrongARM Overclocking Switches
