That's really good to know as it topped out at 40C sitting in the BIOS (I let it stay there about 3 hours and I knew it topped out when I saw it alternating between 39C/40C over and over). Before I realized the stock HSF had thermal paste on the bottom of it (preapplied), I removed it from the chip, realized what the stuff on my chip was, and reattached it. I didn't know if that might have messed up something, so I'm glad to see that it didn't (at least not catastrophically... I know the purpose of the paste is to fill any air holes and provide solid contact between fan and cpu).

What HSF are you running Gramps? Serpents advice is dead on for an easy OC but I wouldn't run 1.465 with the stock HSF. Then again, I'm pretty cautious about these things.
I'm running the stock HSF. I hear about folks buying replacement HSF's and then having trouble making stuff fit in their case. I'm not quite sure I'm ready for that drama yet. On the other hand, I really do think I could have tackled applying Artic Silver 5 (AS5), and it isn't that expensive. I haven't really read up on the benefits of it yet so I don't know if it's a "must do" thing or just something the really advanced folks do to squeeze out that last Mhz. Same goes with the replacement HSF's. I see myself getting a case with some 120MM case fans so overall, the case has adaquate cooling, but I don't think I'd ever get the most advanced HSF's if they are really expensive and/or require lots of contortions to use them. I've seen some HSF's that look like they belong on a drag strip.
Speaking of which, I really like how these computers can monitor so much! Fan speeds, multiple temperatures, etc. It's excellent information to know, especially when you're pushing things a bit. I never really had to worry about it before as I was always running a prebuilt machine from a major manufacturer. That brings me to my question on the 1.465. I'm a bit conservative too, but probably entirely too emboldened by my initial success following SR's instructions. What's the worse that can happen? If I'm understanding things correctly, the machine will either not boot (at which point I can reset things), or it will boot enough that I'd be able to get into the BIOS and notice that CPU temps are way too high and I need to drop down. Am I understanding that correctly? I've seen "heat is a chip's worst enemy" or something to that effect. Is there a relatively direct correlation between CPU temperature and stability? I've read I should be able to assume the chip is OK as long as it stays below 65-70C. If so, my way of being conservative would be to make sure I stay at 65C or below.
You guys have mentioned a few times that I shouldn't install the OS while overclocked. I haven't commented before, but I want to let you know you got through loud and clear. I was experimenting with OC's only in the BIOS just to see what would happen to CPU temps, then going back to defaults. It was a little baby step for me. "Jumping in" so to speak to get the apprehension out of the way.
Oh, one last thing. I know (from reading your link) that there are two types of "CPU" temperature, but I was reporting on the IP35-e's "CPU Temperature" on the "PC Health Status" page of the BIOS. I'm not sure which one that refers to, but I'd assume it's actually CPU temperature and not core temperature as there's only one there. I believe for a dual core machine, there would be 2 core temperatures.
Thanks to everyone for all the excellent advice and help. I don't know if there's a lot of old timers here, but in the early days of overclocking, it was fraught with peril since the clocks were ... "shared". What I mean is if you sped up the CPU, you also sped up RAM, I/O, and everything that depends on the clock since there was essentially only one clock. It wasn't uncommon to be able to speed up the CPU, but have trouble finding a video card that could keep up at the new (non-standard) clock. It was around that time I decided the hassle wasn't worth it. This is a whole new ballgame, and it's a lot more fun to play.
