BSOD's on Vista boot-up if take NB/HT to 2.6GHz, but to be honest, havn't really tried 2.2 or 2.4, but will give it a go soon. Will I notice much speed increase?

Also, is this voltage ok as a 24 hr voltage? Is it decreasing life by much?

1.4v is perfectly fine, because they run so cool I can't see 1.45-1.5 being too much tbh.
I run a higher NB instead of clock because it offers a greater performance boost - my trade off was 100MHz.

u will see a boost..
1.30-1.35v on the cpu-nb will/should get u to 2.6ghz.
amd site says max recommend voltage is 1.5v so u are fine.

It worked 
2.4GHz first time!
Will push for 4GHz soon!

Hmmm I thought HTT speeds didn't make that much difference whereas NB made a lot?

Faster NB is going to mean faster L3 cache so that is important ... though at some point HTT will become an issue if its slowing comms from core to NB/L3
yes but its better to run the htt the same as the NB speed if can.

Hmmm, time for some benchmarks because I found NB more important on my system and HTT made very little difference past 2GHz.

What is the MAX safe NB voltage on a 940?
nobody knows really but 1.30-1.35v is perfectly safe, which will get u to 2.6ghz.

What sort of 3DMark06 scores are people getting?
At 3.4GHz I got 15,552.
When I get a moment I'll run it at 3.9GHz and see the difference.

cpu at 3.7ghz, nb/htt at 2.6ghz, gpu at 745/1145
3DMark Score 15339
SM 2.0 Score 5733

Oddly AMD Overdrive now reboots my PC when I try and run it? 
Does anyone know how to 'reset' it because I've tried a re-install and that has failed.

Highest stable speed i can get is 3.5-3.55 on my 720BE can get into windows at 3.6 but all stress tests fail within minutes tried every possible combination of multiplier/ fsb i could seems like its the limit for my chip upped voltage to 1.5 and nb voltage was at 1.3 but that didnt make any dif
look in c:\Program Files\AMD\OverDrive\DefaultConfig.xml.. maybe try editing it or delete it.Oddly AMD Overdrive now reboots my PC when I try and run it?

Same as my chip!
