I just stumbled on K10stat which has been discussed here quite a bit but I never saw it on an actual thread here. I actually saw a Toms Hardware site guide on undervolting desktop AMD CPU's on the 9th via K10stat. Finally got around to playing around with it on my Laptop and it worked but I got hangs when I tried to undervolt my 2400mhz processor. There was that original power underclocker for vista PumaStateCtrl I never really got my settings down to make it work reliably, and it never worked for me in Windows 7 either. The power states for these AMD mobile CPU's seem to be pretty bad and the performance doesn't feel snappy at all. They seem to have issues going into a useful state that doesn't make the fan blow like a vacuum cleaner. I think the issue is with the lowest power state. I don't think 600mhz is really useful for anything, Onenote really lags at that speed. Well what if I used my low power profile in windows 7 which keeps the processor at it's lowest state at all times not changing power planes and increase the CPU a bit, keeping the voltage the same. Here comes the good stuff. I started at 850 mhz which made basically all web videos stutter free. But I kept on going running prime after each try. 1000 thats great, 1200 wow that is as fast as the second P state normally is at 1.2v but it is running at .8v how can that be. But it passed prime95 torture test... kept on going all the way to the max allowable 1775. IT'S STABLE and I attached a CPUID screen print. I don't understand what is going on. I think it may have something to do with not changing the power planes which made my CPU unstable, when I was trying to undervolt previously? K10stat says CPU at 50c and laptop seems hotter but the fans never come on, maybe some kind of error from using K10Stat or maybe the fans are hardwired never to come on when you have the cpu at the lowest state. I don't want to ruin my like new computer never had any issues with it. Computer is stock other than Vertex 60g SSD, which other than bootup and hibernate times doesn't seem to make any difference. I don't think the SATA controller is actually making good use of the SSD. I was going to take apart my laptop and put some arctic silver on it but never got around to it. I don't even want to think about the battery life I will get now with my 8cell. You don't know how lucky I have been lately with AMD cpu's. I got a phenom II x2 and unlocked the two cores and overclocked it to 3.65 stable on the stock cooler. All I was thinking about next was getting a new laptop but now not a chance. It is silent no roar of the fan, I do have the fan always on in the bios setup but it just stays at that minimal setting no matter what.
