Has the default memory controller voltage been reduced in BIOS ver F6? I am pretty sure the default was 1.3 in F5, but it is 1.187 in F6. Can anyone confirm the F5 default for the Memory Controller Voltage? B.T.W. I took the measurement off AMD Power Monitor. The reason I am asking is that I routinely undervolted it in F5 and earlier by 0.200 volts, but when I did this in F6 it would not get through POST. However when I reset it and then undervolted it to 0.100 volts I got it to boot cleanly.

With what processor? The 9850 you have in your sig?

For me and my 9850 the Voltage goes from 1.3V in Bios F4 to 1.1375 in F5. It is now at 1.1875 in bios F6.

(Sadly F4 wasn't any betterfor me though... it crashed a lot. So far F5 was the "best".)

Sadhiq: I have no problems with my USB keyboard or mouse.

Yeah. It is with the 9850. Perhaps it was the BIOS F4 in which the voltage was at 1.3V and I just did not notice the change in the F5!
Also, I do not have any problems with my USB keyboard. Perhaps the USB settings in the BIOS need to be re-examined?

Sometimes when the F4 rebooted or booted... I got weird "stuff" on a few lines of the bios boot up screen and it would lock. That never happened in F5. It is now back for F6.

Sadhiq: Your friend might have to turn on the legacy USB keyboard stuff in the bios if you use the Windows boot loader and have more than one... or it won't "see" the keyboard until after windows totally boots up. Although you said mouse. I do think I've heard of various motherboards having issues with USB wireless mouse. (Mice?) I use a Razor Deathadder which is wired. (High resolution.)

Guys, my 9850 arrived today. I have a DS5.

Is it worth bothering or should I just send it back right away? I have the X2 6000+ now.

My board has an issue with Logitech MX510 mouse connected via USB. Not sure if its the case with all USB mouses or just logitech mouses,or simply my board/bios is flakey. If I plug-in the mouse before I plug in the PSU cable in the PSU,the mouse sensor starts to glow immediatly and cannot be recognized in windows. Re-plugging the mouse works. If I go by "first psu,then mouse" connecting method it works without problems. As u can assume,this only happens when pc is turned off and u need to reconnect all the cables so really not a big deal,but it is annoying to experience for the first time
