You cannot remove or add Direct RDRAMs to a RIMM because the Direct RDRAMs are soldered on and encased by another material. Do not mix RIMMs with different memory speeds. Performance will reflect the slowest speed RIMM. CAUTION: Static electricity can damage the electronic components of the workstation or optional boards. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object. CAUTION: Your workstation will not function if the above guidelines are not followed when installing RIMMs. CAUTION: When handling a memory module, do not touch any of the contacts. Doing so can damage the module. s s s s 2-6 Hardware Upgrades Installing RIMMs When installing RIMMs, you must use the configurations in the following table.
