ECC DDR5-4800 vs. DDR5-5200 Memory Performance For AMD Ryzen Zen 4
Back when looking at the AMD Ryzen 7000 series budget server performance last year, DDR5-4800 ECC UDIMMs were used with the ASRock Rack 1U4LW-B650/2L2T Ryzen server given that's what was broadly available at the time.
Recently I bought a pair of Kingston Server Premier 32GB 5600MT/s DDR5 ECC CL46 UDIMMs (KSM56E46BD8KM-32HA) and that's the focus of today's tests. The Kingston Server Premier 32GB 5600MT/s KSM56E46BD8KM-32HA ECC Unbuffered DIMMs have a CAS latency of 46 and rated for DDR5-5600 speeds. For this testing it's quite a straight-forward comparison looking at the DDR5-4800 vs. DDR5-5200 performance with an AMD Ryzen 9 7900 processor running with the ASRock Rack 1U4LW-B650/2L2T 1U server platform.
