@ IamMed: I only use the nVidia 5.10s, have done since release on my old Asus A7N8X-E, but thanks for the tip.
Nah, the SATA port in question is hosed, it looks like a B-grade board that I got back as well, thermal paste on the plastic HSF retention bracket and only 1.3 BIOS! I run a Winchester chip godammit.
I did have to update the firmware on my 2 Maxtor Diamond Max 10s though so that this board could restart effectively while they are attached, how bizarre!
On another note, I don't seem to be getting notifications from the OcUK forum admins for new posts in the threads that I am subscribed to, is anyone else experiencing this?
