Questions about this item

Does the ASUS ROG Strix B850-E Gaming WiFi and Ryzen 9 9900X combo include a CPU cooler in the box?

The cooler is not included with the Ryzen 9 9900X, so a separate AM5-compatible cooler must be purchased. The motherboard provides a 16+2+2 power solution rated for up to 90A per stage with dual ProCool connectors to handle the 12-core processor.

Which DDR5 memory speed does the Ryzen 9 9900X officially support on this B850 board?

The Ryzen 9 9900X lists DDR5-5600 support. The board also features AEMP to simplify setup and improve performance with compatible DDR5 modules.

What does the 5.6 GHz max boost figure mean for everyday workloads on the Ryzen 9 9900X?

The 5.6 GHz max boost is the highest single-core frequency the 12-core, 24-thread Zen 5 CPU can reach under load, giving strong burst performance in lightly threaded tasks while the 64 MB L3 cache helps sustained multi-core throughput.
