To provide Intel's latest processors' unfettered access to memory bandwidth, we've reimagined motherboard trace routing from the ground up. Our OptiMem II tech carefully maps memory signal pathways across different PCB layers to reduce vias and also adds shielding zones that significantly reduce crosstalk. And to further enhance overclocking headroom for fully stacked memory configurations, we've employed a highly customized T-Topology layout that delivers time-aligned signaling.
Top layer – ground ring to prevent lateral interference
- Improved memory stability and compatibility
- Allows lower memory latencies at equivalent voltages
- Improved memory frequency margin
Tested by using Synopsys HSPICE simulation software
MemOK! II automatically fixes boot failures that arise due to memory overclocking and instability. When a DRAM-related POST error occurs, the motherboard adjusts memory parameters until the system is able to start.
