This processor is unlocked, meaning that it can be overclocked if you wish, via settings such as the multiplier in the BIOS.

I am just using the stock heat-sink and fan which comes with the CPU. I am using it overclocked at 4.1 GHz (20.5 x 200 Mhz), which is probably a sensible limit, until I fit more substantial cooling.

Once overclocked it provides plenty of processing power relative to the price paid.

The processor is designed to automatically throttle, meaning it will run at a slower speed on lighter tasks, such as web browsing. This saves energy, and produces less heat. The speed will throttle up again, if a more demading task is started.

The included heat-sink fan is nice and quiet.

I have built a new budget system that I use for photo work, video editing and gaming. The important bits are: Antec 300 case, Gigabyte M68MT-S2 motherboard, AMD Bulldozer FX 4100 Black Edition, 8GB of Corsair Vengence 1600MHx RAM, EVGA GTX 550Ti Graphics, OCX 60GB SSD for primary drive and 4 x 1TB disks for storage. There are a number of other small modifications such as a card reader, fan controller and Arctic Freezer 13 heatsink and a 650w power supply.

I currently have this overclocked and the CPU is running as a steady 4.2GHz. The upgraded heatsink ensure that at idle I'm generally getting sub 20oC CPU temps and even when stress testing I've never had the processor above 36oC and that is with a 0.125v increase in the CPU voltage.

I love my new computer and I love the Bulldozer FX-4100 as it really does perform well and I run all games on max settings. I'm not playing things like Metro 2033 or Battlefield 3 but I play Starcraft on Ultra settings and get 59fps even during intense battles and it doesn't even break a sweat.

For the price I would recommend this chip, especially if you intend to overclock it as that will bring the performance up a lot. It won't compete with the newest and greatest the Intel have to offer in the benchmark tests but real world use it seems to be great and I look forward to a good few years of enjoyment to come.

I would definitely recommend an upgraded heatsink if you are overclocking this chip and be aware that it is a very large piece of silicon indeed and is bigger than the base plate on most coolers but that is not an issue. Use a good thermal paste such as Arctic Silver 5.

I finally got my new Bulldozer CPU; I am blown away, and this is why:

With my previous CPU, the Phenom II x4 965, I had considerable heating issues in-which at stock with four cores running, I would reach over 70c, which of course isn't good, so I resorted to tweaking the Vcore, disabling cores, and lowering the frequency, which is also not good. I'm aware that Phenom IIs apparently get rather hot, and I can second this, and some!

This amazing piece of technology runs at an overclocked 4.4GHz (stock Vcore) at an insane temperature of (whilst the fans* on max) 6c idle and 37c on max-load! I have of course disabled Cool 'n Quiet, along with AMD's new Turbo feature, which is to ensure the OC is stable and safe for the CPU.

I was blown away when I noticed the amazing temperatures, and currently, while typing this, with all my fans (including the CPU fan) are at an absolute bare minimum, my CPU is at 10c. I have no fancy water cooling device as you'd expect from these temperatures, but instead I have a mix of Arctic Silver 5 paste well applied and an impressive (yet useless for the Phenom II) Arctic Freezer 13.

I can't enough recommend this AM3+ socket CPU. This CPU will last me for many more years to come and shan't be a bottleneck for a long, long time.

The details of my OC are as follows:

Turbo OFF.
FSB at 200

Be prepared for bios update but works very nicely when sorted. Big improvement on athlon dual core.
Please support the only alternative to Intel while AMD lasts. You will be sorry if you don't. It may be slightly slower but much cheaper.

AMD regains the value option with 4100 FX and for those with a very limited budget it makes a reasoned and rational choice.

Firstly, it is cheaper then the alternative 2120, but offers an extra 3%-5% on average for performance.

Secondly, you're not paying for wasted GPU silicon on the CPU when you've got a proper graphics cards for gaming!

Thirdly, unlike the 2120 this CPU can be overclocked up to 4.6 GHz (4 GHz without voltage increases). An easy gain of 27% in performance, which puts it ahead of 980B, which costs an extra 60% over the 4100 price!

Fourthly, Windows 8 2012 release will see an extra 2%-10% gain in performance through more even threading between cores of workloads. This CPU family architecture is specifically designed for servers which have software with even spreads of workloads for the available cores. Desktop PC's tend to have a lot of software that pile workloads unevenly onto cores. Microsoft and AMD are working together to ensure the new OS has more equal loadings, which is where this extra performance will come from.

Mine's is running 4.2 GHz with no problems. No problems with video games with my Asus motherboard. However, I don't use Steam (I do have an account) and GameStop (formally Stardock Impulse) has not shown any of these problems.

A good value choice during these hard times!
