Although not affected by the product, the replacement of the RAM module by numerous Youtube videos was done well understood and quickly.
The RAM module worked right away, was recognized by the BIOS / OS and produced to this day (after 6 months) no discernible error.
Corsair I was so far never been disappointed.
The product completely fulfilled my expectations, so 5 star and a strong buy recommendation, an upgrade of the installed RAM should be possible.
