[. . . ] If you are using 512 MB DIMMs, all DIMMs in the system must be 512 MB. The memory must be removed in matching pairs (banks are interleaved). For example, if you remove a card from slot 1A, you must also remove a card of equal size from slot 1B. Chapter 1 13 SONY Visualize X-Class Parts Replacement System Board, BIOS and Memory Video Memory The SONY Visualize fx4+ and fx6+ video boards each have 18 MBs of SGRAM memory. They have an optional hardware texture accelerator module with 16 MBs of SDRAM added to them. The SONY Visualize fx5 and fx10 video boards each have 64 MB of installed SGRAM memory. This includes texture memory; consequently, there is no additional texture module accessory required. The ELSA GLoria II video board has 64 MB of installed SGRAM memory and the Synergy II has 32 MB. No switch or jumper settings are need to be changed (all jumpers should be left in the positions in which they were set by the manufacturer). Recovering the BIOS (Crisis Mode) If the BIOS is corrupted and the standard flash cannot be used, use the BIOS Recovery Mode (exceptional BIOS recovery operations) to restore the BIOS. Copy the BIOS files on to the floppy disk. Power off the PC Workstation and remove the power cord. Refer to "Recovery Boot Active Procedure" in the User's Guide for the detailed recovery procedure.

Main Memory The Personal Workstation has four DIMM slots on the system board for installing main memory. The memory must be loaded in pairs, and you can have a minimum of 128 MBytes to a maximum of 2GBytes of memory. When you install the memory, you have to use matched pairs (for example, two 128 MByte DIMM cards installed sequentially according to the memory loading order). When expanding the memory in your Personal Workstation, you can obtain maximum performance by keeping the size of all memory cards the same. If you are using 512 MB DIMMs, all DIMMs in the system must be 512 MB. The memory must be removed in matching pairs (banks are interleaved). For example, if you remove a card from slot 1A, you must also remove a card of equal size from slot 1B. Video Memory The SONY Visualize fx5 and fx10 video boards each have 64 MBs of SGRAM memory. They have an optional hardware texture accelerator module with 16 MBs of SDRAM added to them.
