Get the performance you need at the price you want for today's demanding workloads. The AMD Opteron 4386 Seoul processor has 8 cores and supports U/RDDR3 up to DDR3-1866 and ULV (1.25V) RDDR3 up to DDR3-1333. It can be used in two-way configuration - to achieve up to 16 compute cores in a single system - great for servers and high-performance computing, especially with software that's built to run in parallel. Based on the second generation of AMD's modular core architecture codenamed "Piledriver", the Opteron 4386 delivers significantly higher performance per watt per dollar than previous generation processors.

Run your IT infrastructure, web, cloud and collaboration workloads on a platform built on an ideal balance of enterprise-proven performance and smart business.


• High compute performance with up to 8 cores using Straight-through Computing

• Scalability up to 2 sockets or 16 cores

• AMD Turbo CORE technology for increased performance by utilizing additional power headroom

• Memory bandwidth with 2-channel DDR3 memory controller

• Tremendous I/O bandwidth with three HyperTransport 3.0 technology links between processors and I/O

• Software compatible with existing AMD Opteron processors

• Platform compatibility with today’s AMD Opteron 4200 Series processor solutions



detailed view and application


Innovative “Piledriver” core architecture

Provides the right balance of price-performance per watt by sharing resources–such as fetch and decode logic–to help reduce power and die size, and increase execution units for improved performance. This redesigned architecture optimizes execution paths that help reduce the total power consumption by actually optimizing the way software runs.


New power management and power saving capabilities

New power management capabilities allow for larger parts of the processor to be almost completely powered off when not being used, dramatically reducing idle core power consumption and enabling active cores to run at a higher frequency.

New power saving features like TDP-based power capping put the customer in control of more aspects of power efficiency than ever before on AMD Opteron processor-based embedded platforms.

Consistent platform with Socket C32 and the AMD SR56x0/ SP5100 chipset offers a platform compatibility with existing AMD Opteron 4200 Series processor-based systems.


Reliable, scalable

Reliability is a key factor in selecting server system components. Select SKUs of AMD Opteron processors are NEBS (Network Equipment Building System)-friendly–either with higher Tcase support or p-state control during extreme temperature conditions–supporting telecommunications industry requirements for reliability.

The AMD Opteron 4300 Series processor provides multi-processing scalability options from one to two socket systems. This, combined with the reliability of AMD64 technology, helps enable an embedded design that may provide customers a long range plan for the life cycle of their systems.

5 out of 5 eggsWOW!

Pros: Installed a pair of these on a H8DCL-iF because I didn't like the prices on the xeon E5-2643's.

Was I shocked, for compiling with gcc, linking,running gzip (for packaging) and general integer work these things are incredible. This machine is literally the fastest thing in the lab beating out quite a number of significantly more expensive Intel machines.

Basically, the price/performance of these processors vs the intel E5s is crazy.

Cons: None yet...

5 out of 5 eggsGreat Little Powerhouse

Pros: This is an extremely powerful little processor that runs very cool. It keeps up with modern desktop processors by being able to max out at 3.8GHz when running fewer cores. I grabbed two of these very recently to build a graphics workstation and replace a single older quad-core Intel Extreme processor and I'm shocked by the gains in performance I get with these, and how much lower temp they are because my system is darn near silent (see Other Thoughts below). I would have to say one of the greatest Pros is clearly the cost. I didn't flinch at the cost of picking up two and now that I've seen the results (render times cut to a third from an Intel QX6850) I'm extremely pleased with my purchase. I would recommend this over a Intel Xeon or any of the 'Core' desktop processors simply because you can get more physical cores at a reasonably high frequency, and some programs while multi-threaded don't always play nice with Intel's Hyperthreading (like 3ds Max). So, if you're looking for a budget core-laden beast but don't want to sacrifice clock speed, this is really the best solution.

Cons: There really aren't any. It's just very well-priced for its feature set and capabilities.

Other Thoughts: I went with the Asus KMCA-D8 motherboard (which I don't necessarily recommend but I'll live with it) which fortunately came with the latest BIOS release already supporting the 4300/Seoul chips, so no problems there, just plug 'n' play. torsionbar mentioned there wasn't a great cooler selection but I beg to differ; sort of like his/her selection, I went with the Noctua, though I'm using the NH-U9DO (92mm instead of 120mm fans). This is an excellent cooler and even with two my system is whisper quiet and barely rises above the sound of heavy breathing during long renders, you really needn't look any further.

5 out of 5 eggsQuite nice

Pros: A fast chip with low power, perfect workstation or small server chip. A drop-in replacement for earlier 4200 or 4100 series Opterons, an easy upgrade!

Works perfectly and awesome performance under RedHat Enterprise Linux 6.3. As always, Linux "just works" with high-end hardware like this.

Cons: None really. I wish AMD would publish a product roadmap, so we know what chips are coming up in the next few years.

Other Thoughts: If you are upgrading from a 4100 or 4200 series Opteron, your motherboard *will* need a BIOS update. Visit your mobo manufacturers web site and do the BIOS update *before* you attempt to install this chip! My Supermicro H8SCM needed BIOS upgrade to v3.0 in order to use this chip.

Also, since there aren't many Opteron heatsink/fans out there, I'll share the one I'm using. It's a Noctua NH-U12DO. It's a BIG heatsink, but it's very high quality construction, and it performs well and is quiet.

5 out of 5 eggsVery Happy

Pros: 8 cores @ 3.1GHz
Quite energy efficient
Doesn't run very hot even at 100% load 53C (20F ambient)
Getting 30-35k ppd (with 2 processors) in folding at home on WS2008 R2 while running all my other services etc

Cons: Not many great heatsink options for socket C32
Price maybe?

Other Thoughts: I have 2 of these running in my server along side 8 hard drives and despite the 700W powersupplies that aren't even 80 plus, it currently only pulls about 300W running both CPUs @ 100%, plan to switch to 500W 80 plus plat power supplies which should shave off quite a bit.
