HP Vectra VA 6/xxx MT PC Series Main Memory The PC has three banks on the system board for installing main memory; banks A, B and C. Each bank consists of two sockets. The PC is supplied with 16 or 32 MB of main memory (composed of two memory modules installed in any bank). The PC uses 60-ns EDO DRAM. Memory modules must be installed in identical pairs, so that each bank with memory installed contains two memory modules of the same size and type (both EDO, or both FPM). Main memory can be installed up to a maximum of 192 MB. Video Memory The PC is supplied with 2 MB of video memory. An additional 2 MB of video memory can be installed by adding a D3557B module in the video memory socket. This will make a total of 4 MB. Alternatively, an additional 6 MB of video memory can be installed by adding an MGA-MIL/MOD6 module in the video memory socket (ordered from Matrox); this will make a total of 8 MB.
