Four Powerful Processing Cores

With the Phenom II X4 series, AMD engineers have combined four cores into a single processor, giving you enough processing muscle for even the most highly threaded applications. Each core is equipped with 512K L2 cache, and all four cores share 6MB L3 smart cache between them. AMD has also included an ultra-wide, 4000MT/s bandwidth--enough to support all four cores effectively.

For users, this means that you'll be able to run all the latest software without the slowdown you'd experience with an inferior processor. Your computer will be able to handle multiple programs at once, and high-definition media players and video editors will run smoothly and efficiently. You'll also be able to enjoy next-gen games without any frame-rate hiccups.

Unlocked Multiplier for Powerful Overclocking

If you're an enthusiast looking to push the limits of PC performance, the Phenom II X4 955 makes it easier than ever to overclock your system. The unlocked multiplier allows you to manually increase the chip's frequency far beyond its stock values. You can achieve the best results by combining your processor with a reliable motherboard, high-performance SDRAM, and an effective cooling system. With the right combination, you'll be able to overclock your chip to unprecedented speeds.

Cutting-Edge Technologies for Faster Processing

The Phenom II X4 also makes use of several other performance-boosting technologies, including:

  • HyperTransport Bandwidth: Speeds up communication between the processor and memory, improving overall system performance.
  • Integrated Memory Controller: Actively scales bandwidth uses to match your computing needs, dramatically reducing slowdown.
  • 128-bit Floating-Point Unit (FPU): Allows processor to execute floating-point calculations with extreme speed.
Gaming without Slowdown

PC gaming continues to improve at a breakneck rate, with graphics, physics, and AI growing more realistic each year. But you'll need more than just a good graphics card to keep up with the latest games. For certain games that are heavily threaded, a slow CPU can quickly become a bottleneck for performance and can ruin your gaming experience.

Fortunately, the Phenom II X4 series has been specifically designed to handle CPU-intensive games. With its multiple cores, the processor can manage thousands of high-speed gaming calculations at once. The result is a smooth, immersive gaming experience, free of any stuttering or latency.

The Ultimate in Energy Efficiency and Cooling

AMD products are known for their stellar energy efficiency and the Phenom II X4 955 is no exception. The processor features AMD's proprietary PowerNow and CoolCare technology, which allow the processor to smartly regulate its own energy consumption. Having an energy-efficient computer doesn't just help keep costs down; it also generates less heat and helps your computer to run more quietly. It will even prolong your processor's life cycle, so you can enjoy it for years without having to worry about degradation.

The AMD Phenom II X4 955 Quad-Core Processor is backed by a three-year warranty.

The processor is good, and runs great, but be mindful of the watt requirements of the processor. Even if your motherboard documentation states the motherboard supports that processor model 955, there are 2 versions of it. The 125W and the 95W processor. My motherboard only supports the 95W processor, so this specific processor worked, but very slow. In the end, I traded it with a friend for a slower processor that runs at 95W.

That was my mistake (so no negative ratings), and if you plan to buy this processor, check your motherboard website for the watts supported by the motherboard.

Other than that, the processor runs great, and is very fast. At least it runs great on my friends computer, and he likes overclocking. He's really happy with 'my' purchase at least.

So the product is good, but be mindful of the watts required and do not make the same mistake as me.

I am impressed with this processor at this price/performance range. It scored 7.3 on the Windows 7 benchmark test on bootup of a fresh Ultimate Edition install (not overclocked). It's running at a cool 39 degrees celsius with the Zalman aftermarket cooler (my experience with AMD OEM cpu coolers is that they are loud and barely passable so I am leaving it unopened in the box). I highly recommend this processor with any of the equipment below which I would happily award 5 stars when paired with it:

I like AMD. This processor is the best I have had. Even though I've only built two systems, this processor was everything I wanted and more. I will say that when I first put it to use it seemed to do the same amount of work as my dual core, til I looked online and read how to unleash the beast. Now I convert whole movies in under ten minutes. Which took 30-40 under my dual core. Works through everything I want it to.

I recently did a major overhaul to my PC; upgrading from an AMD Athlon 64 3800+ 2.4 GHz single core to this was a huge leap in performance. Doing so required me to upgrade my mainboard and RAM as well.

Now, with my current specs, right out of the box, CPU usage while playing Batman - Arkham Asylum at full specs and resolution uses around 30% of my CPU resources. ME2 @ about 45% CPU resources.

Enabling AMD's "Cool'n Quiet" feature helps with the noisy OEM fan, reducing the core clock speed from 3200 MHz all the way down to 800 MHz and helps keep CPU core temp down as well. While in Windows 7 Ultimate 64-bit playing a movie in DTS at 1080p my core temp is about 35c. This quad core CPU is awesome.

Combined with expanded video, at least 4 GB of RAM and ample HDD space, you can have a pretty mean setup.

My overall rating? Awesome. Worth the $140.

CPUz reports the core voltage (stock) at 1.192 V, core speed at 799.9 MHz with a x4 multiplier. ( [...] )

Windows Experience Index reports the CPU at 7.3 (of 7.9).

Here's my system in a whole:
CPU AMD Phenom II x4 3.2 GHz 955 AM3 125w CPU
MSI 870-G45 ATX system board
4 GB (2 x 2GB) DDR3 1333 (667 MHz) RAM
2.5 TB HDD (2 x 1 TB SATA, 2 x 250 GB IDE))
nVidia GeForce 9800 GT (eVGA) 512 GB GDDR3 (GPUc @ 600 MHz, Mem @ 900 MHz, Shader @ 1500 MHz)
BFG Tech 650 ATX PSU

For gamers like myself, an up to date processor is essential to an optimal gaming experience. I could've paid an extra hundred for a i5 or i7, but this AMD Phenom II 955 BE processor works great.

I'm using a ASUS M4A88TD-V EVO/USB3 - AM3 - AMD 880G - DDR3 - USB 3.0 SATA 6 Gb/s - ATX Motherboard for the processor. I like the ASUS motherboards because they have good programs that make it easy to manage the fans, clock speeds, and more.

I have nothing but good things to say about this processor. I haven't experienced any problems thus far :

- Using a Cooler Master V8 Nickel Plated Copper Base Aluminum Fins 8 Heatpipes Core i7 1366 CPU Cooler - (RR-UV8-XBU1-GP)and about four 120mm fans in my Cooler Master HAF 912 Mid Tower ATX Case (RC-912-KKN1), the temperature of the processor only reaches 40C on rare occasions. I run games like Crysis 2, Bulletstorm, and Call of Duty Black Ops and the temperature hovers around 36C. Keep in mind that you should invest in a good CPU cooler or 120mm fans.

- 7.5 windows score. For just $140? Awesome.

- The processor rivals those of Intel core 2 quad cores, I5, and I7. Yes, those intel CPUs may be more reliable and efficient, but $140 is well worth it.

*** update ***

After nearly two months this CPU is still running great! Stays cool and never passes 42 degrees Celsius at maximum load witwh a v8 cooler master cooler and 3 fans.
