All - I'm baffled. I have the HP Elitedesk 800 G2 tower PC, with i7 6700. It came with 2 Kingston 8GB sticks of 2133 RAM which worked fine.. I bought my Dad the Elitedesk 800 G2 SFF and swapped the Kingston into that as he needed something ASAP. The SFF came with 2 Hynix 4GB sticks which worked fine in my tower. Then when I tried to upgrade my tower back to what it was, I went with 2 8GB G.Skill Aegis sticks using the NewEgg memory finder, and the fun began. That memory wouldn't work at all. I got an error, I think 2E1, memory size error. Then, after I tried to put the Hynix modules back in, it would only recognize the 4GB in DIMM 1. I swapped the sticks and it didn't matter; it only saw DIMM 1. Then I used Crucial's memory finder and bought 2 8GB 2400 sticks, and again it will only see DIMM 1. CPUID does show the speed there as 2400. The BIOS seems to give no functionality to change anything regarding the RAM settings. Any data I found online basically left me with only the option to swap the Mobo. For $20 I did that, and with the Crucial sticks, it gave 3 nasty beeps then 2, and wouldn't boot. I played around and if I left the Crucial 8GB stick in DIMM 3 only, it booted and recognized it. With a Crucial stick in DIMM 1, no joy. Huh? I'm lost, Is the BIOS stuck in some weird loop? Both boards are using the most recent BIOS. Mobo is called Spitfire Rev A.
