dears, actually i have a modified Alienware M17x R3 with:

- Intel Core i7 Extreme 2960Xm
- Nvidia GeForce GTX 780m 4gb DDR5
- 16GB Ram DDR3

And playin games i saw that the FPS has low performance every some second and using the HWiNFO 64 i see that the CPU is unstable and down from 3,388 Mhz to 797,4 (aprox). Every time that the frequency down i have low fps.
How can i stabilize the CPU frequency?

Sorry, but heat and power are your problems. The original CPU was a 45w device. The new CPU is a 55w device. The new CPU runs hotter (and faster) and it is more than the heatsink can handle. You can try using a premium thermal compound and making sure your intake and exhaust ports are clean, but I really think you need to go back to the original CPU to have any chance of stability.
