HI OCPete,
I updated the bios on my UD5 last night.
I could not find a way to keep the overclock settings so I took photo's of all the bios screens to refer back to.
I then updated the bios to revision 13f and all went well but didn't keep the settings.
I refered back to the photo's and entered the settings, which was a bit more difficult because all the screens had changed format so had to interpret them a bit, but finally got them all in.
Booted up and all worked fine. Ran for 5 hours last night and did not experience the problem of random lockups I was having. Ran Prime and furmark, game benchmarks and played a little games, and was O.K
Just take photo's of all bios screens and all should be O.K
Someone may have a way of saving the settings, but as I said I couldn't find it.
My system was running really well up until a few weeks ago when it started ranomly freezing.
I wasn't sure if it was the waterblocks I had just fitted, but having checked all of them to be O.K, now thinking it is something else, which is why I updated the bios.
What problems have you been having?
