I was activted Windows 8 Pro x64 with following confeguration:
Moder board: Gigabyte GA B75 D3H
CPU: Intel i3 2100
Ram: Corsair XMS3 CMX2GX3M1A1333C9
After that I replace/ upgrade CPU from Intel i3 2100 with Intel i3 3220, but no poblem from activation of Windows.
Now I am trying to upgrade ram from 2Gb to 4Gb, but my activation fail after ram upgrade. So I could not upgrade the ram.
If I place the same 2Gb (Corsair XMS3 CMX2GX3M1A1333C9) ram again, Windows reactivated automaticaly after restart.
Now can you help me how to upgrade ram with activation ?
