So, based on the above and your feedback, if you are are up to trying a different RAM one more time (if your project was mine), I would consider this RAM option. Anyway, just the other day I ordered Samsung RAM for that reason, see my thread. On a number of occasions, Samsung RAM performed (much) better than other -even upscale so-called 'gaming' RAM. To provide some context here, I have been working on a number of legacy HP desktop Upgrade projects, and it so happened that only a limited number of RAM sticks can achieve to run at max RAM speed (2400 MHz) on an HP EliteDesk 800 G3 SFF (Small Form Factor) -Samsung being the best option based on personal previous experiences with RAM. To that end, if you could reinstall the 8GB RAM Samsung stick and run a freeware program called ' Speccy' (a very useful performance-measuring software utility anyway), you can get the free version here: and provide the actual RAM speed in MHz as well as the CAS latency -such as 19-19-19-43 as shown in the picture attached below. It would be most helpful to know at what speed it ran -runs. The Samsung 8GB RAM stick that worked for you is rated at 3200 MHz, and must have cycled down to work at 2400 MHz or 2133 MHz without any issues. plot thickens! Very interesting indeed.Business PCs, Workstations and Point of Sale Systems.
