Hi all,
sorry i got sick and was laying for few days.
@Dzeronimo: E388 i guess is a part of GPU "series" numbering or so, these were delivered to use late 2017. Nowadays we get E387, its is part of P/N number.
@jmigdlc99/jillscarbrough: Why not backup? Its simple, at the time we got the i forced few of GPUs with other versions, it has no bad effect, but if you are going to give the product back due to HW errors ( normal warranty procedure ) they can easily find out if was BIOSed, because the P/N will not fit. Can be seen on the card label - middle part.
So the only reason to have it back at E388 is in case we will need to claim the warranty of product, to be on the safe side.
Thanks
