    Dear all,

    Just last night i installed an opteron 170 to replace my 144. Everything went as well as I could have hoped. I didn't touch my BIOS settings (which was at 299x9) and the 170 fired up to windows before it crashed (which is still bloody good seeing as it was quite a steep ovrclock).

    Anyway, I've got it stable at 2.725ghz so far, but I am limited by votage. Previously I had the option of going to 1.55v, now that option stops at 1.5v. Any ideas how to get it back? I figure a BIOS update is in order, but I don't know which one.

    Can anyone with the same motherboard and a dual core CPU let me know what they are using and how it works?

    according to asus its because you get a voltage increase of 0.1v over the standard which is 1.35 for an opty 170 and a small increase above that giving you your 1.5v. fo the 144 the default voltage is 1.4 giving you more volts higher voltage but the same relative range increase

    Interesting. Annoying, but interesting. Thanks very much.

    Is there any way to dupe it and push the range up at all?
