AMD Phenom X4 9550 Quad Core Processor
Now that quad-core processors have been successfully launched in the desktop computing market, people are eying the switch to these powerful multi-core CPUs more seriously. These processors deliver the performance of four processors, and with the AMD’s introduction of affordable quad-core processors like the Phenom X4, everyone has an attractive upgrade path for their existing Socket AM2 system. Like the rest of AMD’s Phenom series, the AMD Phenom X4 9550 Quad Core Processor is capable of clock speed increases and improved memory performance.
A Better Quad-Core
For less than $200, you get to finally experience true quad-core performance. If you want great power for less price, then you should definitely consider the AMD Phenom X4 9550 Quad Core Processor. Its quad-core architecture is largely different from what the competition offers, because four of its execution cores sit under a single die. Like its other Phenom brothers, the 9550 features a built-in North Bridge with a memory controller and L3 cache working at their own frequency and voltage. This ability distinguishes Phenom processors from the previous-generation Athlon 64, in that the older generation’s memory controller and L3 cache are dependent on the frequency and voltage of the main processor core.
The AMD Phenom X4 9550 Quad Core Processor has 512 KB of L2 cache per core and 2 MB of shared L3 cache. The L2 cache provides enough memory for running multi-threaded operations, and the L3 cache enables faster operation in single-threaded code. These caches work so well that they deliver incredible performance for both multi-threaded and single-threaded applications.
Aside from its noteworthy architecture, the AMD Phenom X4 9550 Quad Core Processor has a processor speed of 2.20 GHz and a 1800 MHz Front Side Bus speed. These specs allow seamless processing of data even when running demanding applications. Sure, these may not be the most impressive numbers; however, the true strength of this processor lies on its true quad-core nature. The 2.20GHz speed might be misleading: the AMD Phenom X4 9550 is running at 2.20GHz per core. And even though it’s made through 65 nm manufacturing technology, AMD claims it is capable of some 45nm processing power. For instance, the 9550 has a thermal design power of 95w, which is in terms of power efficiency, well above average.
The AMD Phenom X4 9550 Quad Core Processor also has HyperTransport 3 Technology that regulates the amount of power coming from each core for greater computing efficiency. 
Other technologies like AMD Cool ‘N’ Quiet 2.0 and CoolCore further enhance computing efficiency by working together to conserve power when the system is in idle.
With all these capabilities, the AMD Phenom X4 9550 Quad Core Processor promises to give you advanced performance quality and reliability in both games and digital media applications. Tweaked to perfection, this capable quad-core processor is an obvious choice for those AMD fans out there finally ready to go Quad-Core.

I would like to get some more info on this PCU along with what motherboards and video cards are compatable with it. If you can help me I would really thank you by buying the complete set if the price is right.
Thanks a million.

Hello, I just bought an AMDX4 9550 and replaced my Dual core. However I noticed that I no longer have dual channel capability in my physical memory. I have a GA-MA790FX-DQ6 Gigabyte mother board which allows this. I had dual channel when I was using my dual core. Now in the BIO rather than dual channel it shows ‘Unganged Mode’. Could you please help me to get it back to dual channel. I have 4 x IG of RAM per slut. Thanks
