Combo for AM5 builders
This bundle pairs an ASUS ROG STRIX X870E-H S MIKU motherboard with an AMD Ryzen 9 9900X processor. The 12-core, 24-thread CPU runs up to 5.6 GHz and includes 64 MB L3 cache. The board targets enthusiasts who need robust power delivery and extensive connectivity for demanding workloads. It fits the AM5 socket used by Ryzen 7000, 8000 and 9000 series chips.
PCIe 5.0 and DDR5 limits
The platform provides one PCIe 5.0 x16 slot and two PCIe 5.0 M.2 slots when a Ryzen 9000 or 7000 processor is installed; with Ryzen 8000 the primary slot operates at PCIe 4.0 x8 or x4. Memory tops out at 256 GB across four DDR5 slots, with dual-channel support and speeds beyond 8000 MT/s via overclocking. Four SATA 6Gb/s ports remain available regardless of CPU generation.
12 cores and 5.6 GHz boost
The Ryzen 9 9900X delivers 12 cores and 24 threads based on the Zen 5 architecture, reaching a 5.6 GHz max boost clock while unlocked for overclocking. This core count and frequency combination defines the performance ceiling for rendering, compilation and multi-threaded AI tasks. The CPU also brings 12 MB L2 cache and native DDR5-5600 support to the AM5 platform.
