Question about Corsair Vengeance LPX

I think it's a Dell Optiplex 7040, isn't it? But Dell motherboards are unfortunately known to be relatively painful in terms of RAM, so no guarantee I would say. Maybe a RAM from Crucial would be safer as they guarantee to work with the Dell 7040: https://www.crucial.com/compatible...)
I'd have to look into getting a reference from Digitec which is on this Crucial page and that should work.

Hello,
I can't find the reference of your DELL. It is a tower format and not an all-in-one?
If I have found your current RAM, it is compatible.
Just check:
1: That it doesn't look like ! this one in terms of width: HyperX Impact (2x, 16GB, DDR4-2666, 260-pin SO-DIMM)
2: That there is room for a few more millimeters in height.

If so, it's all good :D
