The modules make a high-quality impression. I have installed the modules immediately after delivery in my PC (Medion 8008). These were recognized after booting immediately and work. The increase in speed is really good and it is fun again with my old computer to work very reliable machine. I'll keep now still continue. I am annoyed that this time I have not made that investment sooner.
The instructions in this company for compatibility and for which machines the modules are suitable when selecting very helpful.
