PHS-memory RAM suitable for HP Pavilion 595-p0002nl

This 8GB RAM is 100% compatible with the HP Pavilion 595-p0002nl. What should you consider when upgrading RAM? The fast dual channel mode operation is optimally supported with paired installation of the memory. 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.
