It's good policy to plan ahead so as to allow an increase in capacity to 32GB. I've noticed this effect too in Passmark baselines.ĥ. I had a z420 (E5-1620) that had 4X4GB + 4X 2GB and the memory benchmarks were noticeably better with 4X 4GB only. The best performance appears to occur when the modules are all the same capacity- I don't know why, perhaps something to do with the progressive memory saturation. Place the larger capacity modules in the 1st channel (black slots).Ĥ. The memory will work better if both channels are complete, that is: 4X + 4X. However, do not mix PC3 with PC3 L- the "L" meaning the RAM will run at a lower voltage when possible. Use only memory having the HP part number on it.Ģ. There is nothing that prohibits a 4X 2GB + 2X 4GB memory configuration in a z620.
