It does the job, I'm delighted.
I have to say that it takes a while to boot win10 (on .m2), I must have missed something... when I put the "ultrafast boot" option on it, it screams at startup (5 beeps...)
After some problems with this card not supported by LDLC (my mistake). ASrock exchanged the card for 40€ (15 days delay).
Please do not hesitate to contact the manufacturers.
I have to say that I'm very happy with the quality of the product and the price of the card.
