I received my px-760sa just a few days ago. I get really bad performance. Burn speed (DVD) never exceeds 0.5X. Read speed is somewhat better at 2.5x.
I’ve been looking for a list of compatible motherboards, but mine (Asus A8V Deluxe with K8T800 chipset) is not present. I’m using the latest Promise SATA378 Raid Controller from 2003. I’m using Verbatim media and Traxdata. I’ve read another post with the same problems, but using an earlier firmware hasn’t helped me. Neither has the “trick” with holding the eject button for 5 secs changed anything.
Also, while performing the read test using Plextools, the CPU usage is 100% constantly. Weird.
Any other suggestions?
