Summary: I too bought the Opteron 280s code OSP280FAA6CB. This product was needed to give me two CPU's in my Ultra 40. This workhorse of a deskside server is used for dual booting different O/S's and even does VirtualBox very well. No issues with this product.
Summary: The CPUs I bought were actually a pair of Opteron 280s code OSP280FAA6CB, which are the low Wattage processors and ideal for a game server workhorse. These 68 Watt CPUs are severely underrated- which run cool even with a passive heat sink!
Excellent price/performance upgrade for your dual Opteron motherboard.

Summary: Purchased as an upgrade to my Dell xw9300 workstation (upgraded from one single core opteron 252). Now have 4 cores (2 x 2 cores) vs. 1, and with an 8 MB memory upgrade, this workstation now runs Windows 7 without any slowdowns or hiccups. The upgrade pushed performance pretty close to that of my main PC which is running an Intel Core2 Quad Q9300 at 2.5 GHz. Price / performance is really good right now (as of Nov 2011).
Great CPU for the money, now and back in the day...

Summary: Purchased this product as an upgrade to a motherboard/cpu combo. I'm certainly pleased by the performance of these chips, rating 6.8 in Windows 7 WEI. They do tend to run a bit hot. I have mine paired with copper plated/heat-piped coolers and they idle one core at 50-55C. The other core runs a more modest 40-45C. On both CPUs it's like this. It's possible it has something to do with the configuration of my Tyan motherboard.
A good way to save when building a lower powered server with used parts.

Summary: An excellent CPU for its time. Its performance compares to the first generation Core 2 Duo from Intel. The DDR-400 registered memory that it uses can be found at quite a low price on eBay. It's basically the same design that AMD still sells today, but with a slower dual channel DDR-1 memory interface. That's why AMD is not want you want if you're looking for new hardware to make a high performance computer.
Summary: This set of dual core Opterons at 2.4Ghz are excellent value for money, very inexpensive and performing at the same level as any modern dual or quad core processor from AMD or Intel, I'm using them in a dual socket motherboard to add 4 cores in total, plus doubling the I/O performance compared to a single socket quad core processor, the work cool and overclock as crazy, being Opterons what else can you expect.
Summary: Performance vs Power consumption 5 to 8 Performance vs Maximum Heat Generated 2 to 7 Performance vs Price(Retail 2011) 6 to 9 Overall good performance,SUPER bad FSB bottleneck when coupled in multi CPU systems.Generates lots of heat and offers decent performance when engaged in multi CPU configs.Also does not have support for may new technologies (instruction sets) as the new cpu-s.
Summary: We chose this processor because it balances performance and price. Our budget to upgrade our server to a pair of Opteron 280s was $40, and the 285, the next step up, was something like $40 each. Considering the only difference between the 280 and the 285 was a 200mhz increment in clock speed, we decided that the 280 was best for us. We upgraded from a pair of Opteron 246 which are single core at 2.0ghz, so this is a doubling of our processing ability.
