performance, and overall server power consumption. Therefore, choosing the right memory is the key to ensure high reliability and performance, and to deliver a faster return on your IT investment. HP SmartMemory is a unique technology introduced for HP ProLiant Gen8 Servers. Unlike third-party memory, HP SmartMemory has passed the rigorous HP qualification and test process. More important, verification of HP SmartMemory unlocks certain performance and high efficiency features optimized for HP ProLiant Gen8 Servers: HP SmartMemory uses up to 20% less power than third-party memory while achieving the same performance. At low voltage (1.35 V), HP SmartMemory operates at DDR3-1333 MHz with one and two DIMMs per channel and at DDR3-1066 MHz at three DIMMs per channel. In comparison, third-party memory requires 1.5 V to achieve the same performance. HP SmartMemory performance is 25% higher with Unbuffered ECC (UDIMM) memory and capable of supporting 1333 MT/s up to 2 DIMMs per channel at 1.35V. Third-party memory supports 1066 MT/s bandwidth at higher operating voltage (1.5V). In addition, HP SmartMemory will provide enhanced support through HP Active Health System and HP iLO (see ―Server management-HP iLO Management Engine‖). HP SmartMemory is ideal for HP ProLiant Gen8 customers who are looking to extract all the memory performance, dependability, and power savings that ProLiant Gen8 servers are designed to deliver. HP Advanced Memory Error Detection Technology Uncorrectable memory errors can cause applications and operating systems to crash, so they are costly in terms of downtime and repairs. The best way to prevent unnecessary DIMM replacements is to filter out superfluous errors and identify critical errors that can lead to a shutdown. You can no longer rely on simple error event counts on systems containing up to 14 trillion memory transistors. With HP Advanced Memory Error Detection Technology, we re-invented a precision system that pinpoints errors that cause downtime. HP Advanced Memory Error Detection Technology seeks out specific defects that either cause performance degradation or significantly increase the probability of an uncorrectable (nonrecoverable) memory condition. By improving the prediction of non-recoverable memory events, this technology prevents unnecessary DIMM replacements and increases server uptime.

Power efficiency and provisioning We developed HP Common Slot Platinum Plus and 750 W Common Slot -48VDC Power Supplies to be the most efficient server power supplies in the industry. We also added internal thermal sensors- HP Sea of Sensors 3D-to selected PCI Express option cards. Our provisioning tools reduce the uncertainty in determining expected and worst-case power requirements for servers. HP Common Slot Platinum Plus Power Supplies HP Common Slot (CS) Platinum Plus Power Supplies have 94% efficiency at 50% utilization, meeting 80 PLUS specifications for Platinum certification. In addition, our engineers increased power factor at lower utilization levels and made improvements to minimize total harmonic distortion (THD). CS Platinum Plus Power Supplies also support HP Power Discovery Services (Intelligent Power Discovery technology) to minimize certain power distribution problems and wiring errors. 5
