      Nitrous For The M17x!

      Upgraded a M17x with this QX9300 processor as it is the fastest extreme quad with a unlocked multiplier. I have it on default on multiplier selection on bios and haven't tried any overclocking yet. Slapped on some Cruise Missile thermal paste. Runs real cool for every day computing with Windows 10 Pro, picture editing programs, video editing programs and DJ programs. I did notice a boost higher than the previous Q9100 processor. I'm happy with it. In the near future I will overclock to see what's my highest stable clock. My M17x boots Windows 10 Pro in less than 10 seconds with the QX9300, SSD, PC3 10600 8gb memory. Not BAD for a decade old laptop.

      Put pep back in my laptop's step

      I have an ASUS G72GX, which was originally equipped from factory with a Q9000 quad core @ 2.0ghz. Finally decided I wanted a little more for a dated machine, and bought this CPU to slap in, and I couldn't be happier. With the higher frequency and unlocked multiplier, as well as more adequate cooling, I was able to overclock my laptop to 3.06ghz with this CPU. With the overclock, the performance is great, as well as the temps.

      Efficient CPU Upgrade for Core 2 Duo Dell m4400 Laptop

      The Intel QX9300 was a nice upgrade for the m4400 Dell Business Laptop. This Quad Core QX9300 CPU idles quietly around 3% CPU usage, as compared with 75% with the OEM Intel p8700 CPU, or 60% with the OEM Intel Q9100 Extreme CPU. The QX9300 only supports 4 threads, as compared with 8 threads used in an Intel i7 class CPU, but it still handles most operations efficiently in both Win 7 Pro x64 and Win 10 x64 platforms.

      Experiment

      Tried to install this CPU into a laptop with the PM965 chipset which is 800MHz and it failed miserably. I gave it great ratings because this processor was never intended to be installed in a 800MHz system.

      Good CPU for light overclocking

      Good CPU, but marketed as "open box" meaning unused. It had clear indications of thermal paste, therefor it had definitely been used. Either way it does the job well. Overclocks well.
