Hi, i run a company called SWM Electronics Repair, I fix all kinds of Electronic Devices, Laptops, Desktops, Phones, Tablets, Gaming console's, (PS5 PS4, X-Box 360, series X, series one, slim lines, T. V's up to 43")
A-Tech ram is just as good as corsair, Quality of the A-Tech ram would be better if it has like a heat shield on it, idk if it would work all that well with it on but at least maybe give it a shot in the R&D Department.
Looks pretty good from my end, needed some ram for testing laptops and Chromebooks, Not the only set ill be getting ill have different values and variable speeds, and the condition is excellent.
