PHS-memory 32GB RAM memory for ASRock H270 Pro4 DDR4 UDIMM 2666MHz PC4-2666V-U

This 32GB RAM is 100% compatible with the ASRock H270 Pro4. What should you consider when upgrading RAM? The fast dual channel mode operation is optimally supported when the memory is installed in pairs. If you are using a Core i5 or Core i7 processor, you can only use UDIMM memory. If you are using a Xeon processor, you can use either ECC UDIMM memory or UDIMM memory without ECC. The ECC function is only supported if all installed memory modules are UDIMM ECC memory.
