AMD Opteron (3)

Opteron recall

AMD has recalled some E4 stepping-revision single-core Opteron processors, including x52 (2.6 GHz) and x54 (2.8 GHz) models which use DDR memory. The following table describes affected processors, as they are listed in AMD Opteron x52 and x54 Production Notice.[5]Max P-State
Frequency Uni-Processor Dual Processor Multi-Processor Package-Socket
2600 MHz 152 252 852 Socket 940
2800 MHz N/A 254 854 Socket 940
2600 MHz 152 N/A N/A Socket 939
2800 MHz 154 N/A N/A Socket 939


The affected processors may produce inconsistent results in the presence of three specific conditions occurring simultaneously:
The execution of floating point-intensive code sequences
Elevated processor temperatures
Elevated ambient temperatures

A software verification tool for identifying the AMD Opteron processors listed in the above table that may be affected under these specific conditions is available only to AMD OEM partners.[citation needed] AMD will replace those processors at no charge

Future
Future Opteron processors will see an implementation of the Shanghai core based on a 45 nm fabrication node and codenamed Istanbul products in early 2009, later in 1H 2009- 2H 2010 the lineup will be replaced with codenamed six-core Sao Paolo and twelve-core Magny-Cours products manufactured using the MCM technique, utilizing Socket G34. Further, the server line of processors will incorporate the newly announced Bulldozer core with native 4 cores or more configurations on 32 nm process, each supporting SSE5 aimed at better HPC and cryptographic computations. Currently,[when?] Bulldozer-based products are expected to be released in 2011.
