Introduction Memory is one of the most critical components in a computer. To maximize system uptime it is vital that memory modules operate correctly. HP is a wellknown and respected manufacturer of memory modules. HP memory is manufactured to the highest quality standards and undergoes the most rigorous of testing procedures to ensure 100% compatibility and reliability under even the most adverse conditions. Customers using HP memory can therefore have the highest confidence that they have minimized one of the most significant sources of data loss in their computers. The Importance of Memory Quality for Servers Server requirements for memory quality are considerably more stringent than those for desktop PCs. Keep in mind that the primary consideration in the manufacture of memory for desktop PCs is reducing cost. Consequently, memory for desktop PCs is designed and manufactured with the very minimum number of chips possible. This memory does not have parity bits and therefore cannot store the information that would allow the PC to detect and correct memory errors. Defects which exist or develop in the memory subsystem will eventually cause the PC to mysteriously crash. The stand-alone desktop PC user can periodically save his or her work to the hard disk to minimize the consequences of such an occurrence. But while purchasing lower-cost components and reducing manufacturing cost might be acceptable with some desktop PC environments, such practices can be catastrophic with servers. Servers typically process far greater amounts of data than stand-alone desktop PCs and must be available 24 hours per day, 7 days per week. For server applications, memory modules and other server components must withstand prolonged heat and electrical exposure. The slightest manufacturing defect can become a problem after continual use in such conditions, resulting in mysterious server crashes and irrecoverable data loss for multiple users. 1
