Have you ever seen a riser that stop working before cos I've not, most times it's always the usb cable that follows the riser, changing that will solve the problem instantly unless the riser is a victim of burnt case
Up until late the version 009s has been the best for me and I am still using them.Some of my friends though are using these new risers,new version 010 without any letter behind and they have four led lights for easy troubleshooting,my friends have said to me these are the best risers,I do not have any of these myself but I think I should trust them as I have only seen good reviews about these latest generation risers.Usually good versions come with good quality cables
There is that saying that I got 99 problems and a bad riser is all of them though which indicates that best motherboards without such problems are branded (not chinese non branded) motherboards with 6 x x16 Pciex slots for eliminating the riser problems.
