About this product

Product Information

You can experience the effect that a powerful processor can have on your laptop's graphics capabilities. With the Intel Core 2 Extreme QX9300 quad-core Penryn 2.53 GHz microprocessor, you get four distinct cores and threads. This benefit can enable your device to multitask more effectively, even when you have multiple applications running at the same time. The system can automatically delegate different tasks to each core with precision and ease. The Intel Core 2 Extreme QX9300 microprocessor can support some of the most demanding software. Possible applications include data analytics, complex 3D modeling, video editing, and multimedia entertainment. It can also play casual games. By overclocking the processor, you can achieve clock speeds much higher than the base frequency of 2.53 GHz.The Intel Core 2 Extreme QX9300 2.53 GHz microprocessor features a streamlined and improved microarchitecture. It is based on the Intel 4 Series Express chipset family. It can deliver quality results for laptops, notebook, and mobile platforms. With Intel's Advanced Smart Cache system, each core in these processors can dynamically access the 12 MB of cached storage space. That can keep data flowing smoothly, minimizing the risk of bottlenecks in the RAM. Moreover, the microprocessor features a 1066 MHz front side bus (FSB) architecture. This controls the transfer and flow of data between the different parts of the CPU. This 2.53 GHz chip also delivers 64 bit computing, which can handle more information than a 32 bit system.The Intel Core 2 Extreme QX9300 2.53 GHz microprocessor has been designed with many advanced technologies in mind. The Intel Dynamic Acceleration technology can allow for flexibility. The system can automatically increase the clock rate of one core if the other cores are idle. The Intel 64 system can automatically improve the processor's performance when it is running 64 bit software.Intel Virtualization creates multiple virtual machines on a single system. That can be especially useful for businesses that need flexibility, scalability, and limited downtime in their platforms. The chip also features an Execute Disable Bit technology for enhanced security. The chip can automatically close off certain parts of the memory in the event of a threat. It can then refuse to execute any malicious code that tries to infiltrate into those spaces.The Intel Core 2 Extreme QX9300 2.53 GHz processor can leave behind a smaller carbon footprint, power usage, and thermal envelopes than previous editions of this hardware. You can enjoy the versatility and efficiency of this tiny CPU. It can stay green by drawing slightly more than 1V of power for its high level functions. The Intel Enhanced SpeedStep system changes the voltage and frequency of the system in response to demand on the CPU. This can help the chip function at more efficient level. This can enable you to balance the performance and power saving needs of your laptop or mobile system.These CPUs are designed to work under many circumstances. The temperature of the processor's die will never exceed 100 degrees Celsius, or 212 degrees Fahrenheit, under normal conditions. It also has a thermal design power (TDP) of 45 watts. This is the amount of power that the processor dissipates under highly complex workloads. It's compatible with a PGA478 socket on your computer's motherboard.

      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.
