X9000 works in a Portege M700

Right now I am running prime95 and with RMClock undervolting the CPU to 1.2375 at the 14x multiplier (2.8ghz!) it is running 72c-75c (as reported with RMClock) with an ambient temp of 26c. This is about 3-5c above what I was running with the T9300. Other notables are that the CPU cannot be overclocked through the BIOS (no big surprise there, not that I would do it *much* anyway). Also, when idling before undervolting it seems to run about 10c above where it did before, but I think with some RMClock tweaking I might be able to bring this down a bit.

*Don't ask why. I don't game and doubted that I could overclock it. I did this to prove that it could be done, and doing these things makes me happy*

 

So, the day after...


Well, I've gotten RMClock to undervolt the CPU to 1.1125v (as low as I can take it) at the 6x multiplier and my temps are still hovering at 36c so I think I'll just have to accept the slightly warmer temps (which is still not hot by any stretch of the imagination). Interestingly, I've been able to drop the 14x multiplier to 1.1500v and this makes a significant difference. When running Prime95 I am back at about the same temps that I was with my T9300 (68-70c). What I assume is going on is that my CPU is running 50% "faster" when idling (1200mhz vs 800hz) but is only running 12% "faster" when being stressed. Since I never tested my laptop for battery life with the t9300 I don't have a way to accurately gauge the difference, but according to the RMClock battery monitor, I lost about 40 minutes dropping from about 4 hours to about 3 hours 20 minutes. I'm not sure how accurate these numbers are, but I would assume that I would lose battery life... not that it makes much of a difference to me since I have my laptop plugged in 95% of the time, and the other 5% I am never even close to totally draining my battery so even a 25% drop in life would not impact me much if at all.
