All objects with Barcelona chip

Barcelona was launched on September 10, 2007 as Opteron 2348 and 2350 which frequencies of 1.9 GHz and 2.0 GHz.

In November it was discovered that the CPU's had a bug (the so called translation lookaside buffer or TLB-bug). In rare occasions this could lead to a crash. Using BIOs updates it was possible to disable cache for paging tables to avoid the bug, but at cost of 5% to 20% performance.

The new B3 stepping, launched in April 2008, included a fix for the TLB-bug.
