Reviving old Dell Optiplex 780 MT - RAM problem
Hello, today i brough a kit of ddr3 memory to my old Dell Optiplex 780 MT but it doesnt work. Seller stated that the memory is OK, but trying to run it its giving me black screen and memory problem beep signal. I checked the other slots, every single one works fine with other memory but not with the one i brough. Is the memory incompatible with my Dell? Here is the problematic stick:

I am not mixing anything, i put this stick into DIMM1 slot while the rest of slot is empty, I'm curious if this stick is not working with Dell 780MT or if it is broken

You cant mix and match ANY OLE Joes crab shack ram and it works.
You also cannot mix ranks and Density.
The ram you have in the picture is dual Rank High Density and too slow ram and wont work.

Recommended Ram is faster and Low Density and works.

There is literally no difference between 1333 and 1600 on old hardware, that was tested and benchmarked a lot of times. But if its not compatible that answers my question, thanks
