Impeccable
I wanted to give my old Gigabyte EX58 UD5 based CM with a valiant i7 950 and 6GB of RAM a bit more air. I'm not disappointed, it doesn't do anything other than install these strips to replace the 3 x 2GB I had before.
I'm running Linux and often run another Linux VM that I was allocating 2GB to. This is a bit short in some cases. Now I've allocated 4GB without it sacrificing the main OS, it's perfect.
As usual, the seriousness of LDLC, from ordering to delivery, means that I haven't changed suppliers in over 15 years.
