From our conversation on a separate thread, I have a very similar work issued laptop, so if you'll post some instructions, I'll see if I can replicate the issue.

A cooling pad might be an option for some, but I use a docking station, so that makes it impractical. It's held off the desk, though.

See, I wouldn't have called that throttling. Speedstep/PowerNow! and friends, in my mind, aren't throttling, because they're voluntary. Every laptop I've owned for many years now performed some sort of clock modulation to increase battery life. My OP special takes itself down to 800MHz no matter how much battery is available, even while plugged into a 180W AC adapter. It's also impossible to bring back up off 800MHz until the temps have had time to drop. That's my personal definition of throttling. Clock modulation which you do not and can not control, counter to a workload, to ameliorate or eliminate a negative condition (heat in this case).

Power management that kicks in and reduces the clock because the system doesn't *need* the extra horsepower is a different thing because it does not materially degrade the user experience (assuming it is implemented properly).
Bottom line: Is the processing power you paid for available when you ask for it?

Plugging it into outlet causes it to reset back to 1.3 GHz immediately... Not sure if Samsung set the laptop to be locked at 800 mhz under battery mode, but I'm replacing this laptop during the summer.

I came across a similar problem with a friend's Asus laptop. The thing wouldn't go over 50% clock-speed no matter what I did in Windows power management. Figured out it was an Asus "energy saver" bloatware that was overriding Windows power management. As soon as I removed the bloatware, everything returned to normal. I would imagine there's something similar going on with your laptop.

It is akin trying to put a V12 into a typical compact 2-door sedan. The chassis simply cannot handle the engine. The average customer-grade laptop isn't design to handle desktop tier CPUs under heavy, long-term loads.
Why do OEM manufacturers do it? To make laptops look better on paper than what they are in practice. It is typical used car salesmen style tactics.
