Central Processing Unit (CPU) The motherboard comes with an onboard Intel® Celeron™ Quad Core Processor and a specially designed CPU heatsink. Intel J3455 J3455M-E System memory J3455M-E CPU Overview This motherboard comes with two Double Data Rate 3 (DDR3/DDR3L) Dual Inline Memory Modules (DIMM) sockets. A DDR3 module has the same physical dimensions as a DDR2 DIMM but is notched differently to prevent installation on a DDR2 DIMM socket. DDR3 modules are developed for better performance with less power consumption. DIMM_A1 DIMM_B1 Attention: If only one DDR3 memory module is going to be installed, be sure to install it in DIMM_A1. Channel Channel A Channel B Sockets DIMM_A1 DIMM_B1 J3455M-E J3455M-E 240-pin DDR3 DIMM sockets • The default memory operation frequency is dependent on its Serial Presence Detect (SPD), which is the standard way of accessing information from a memory module. Under the default state, some memory modules for overclocking may operate at a lower frequency than the vendor-marked value. • You may install varying memory sizes in Channel A and Channel B. The system maps the total size of the lower-sized channel for the dual-channel configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation. • Always install DIMMs with the same CAS latency. For optimal compatibility, we recommend that you install memory modules of the same version or date code (D/C) from the same vendor. Check with the retailer to get the correct memory modules. • Due to the chipset limitation, we recommend that you use single-sided 4GB or 8GB, or double-sided 8GB DDR3 per DIMM slot. The maximum memory for the two DIMM slots is 16GB. • For system stability, use a more efficient memory cooling system to support a full memory load (2 DIMMs) or overclocking condition. • Refer to www.asus.com for the latest Memory QVL (Qualified Vendors List).
