Hi guys.
I have this old Dell Optiplex 780 (model with largest case) that has 2 x 4GB installed by manufacturer.
The old functioning ram sticks: Kingston KP223C-ELD
Have been looking for compatible upgrade sets, I found that only Crucial seems to have a set of RAM sticks that is listed as compatible on Crucial web site. This is a pair of of 4GB DDR3L-1600 CT51264BD160B sticks.
However, when attempting to boot - I get this instant long beep (about 2 sec on, 2 sec on) that continues for about 6-8 cycles (roughly estimates) indicating ram is not compatible at all.
The original Kingston sticks were seated in slots 1 and 2, so the new Crucial sticks were seated the same. I also tested with only one stick in slot 1, but same results.
When I put the original Kingston ram sticks back, everything works normally.
According to various sources on web, including the Optiplex 780 service manual says it should not be necessary to reset bios so therefore I haven't done so.
So, this being a pretty old computer and upgrading it was always quite dubious from the start (latest available bios seems to be dated in 2011 and bios versioning system doesn't seems to add up) this is not being s serious project of any kind.
But the one thing that nags me is that I feel I should have been able to somehow figure out in advance that this pair of RAM sticks would indeed not work with my old Optiplex 780.
So the only question I'm left is this: Could I have draw the conclusion of the ram sticks not working on the Dell Optiplex 780 before purchasing? Preferable not resorting to user forums (because I assume probably very few if none at all that has ever attempting a similar upgrade)
[edit]
forgot to mention one detail: The bios version is A15, released late 2013.
