frequency, but report support for 1333 MT/s.The value in the DDR3 Maximum
Frequency Capability (CAPID0_A - Capabilities A Register Device 0; Function 0;
Offset E4–E7H; bits [2:0]) may indicate a higher than expected value of 110b,
specifying that the memory controller will operate at a maximum of 1333 MT/s. The
memory interface will operate as per the table below.

Implication: There may be a slight increase to power or thermal characteristics at the faster
memory speed. At the faster memory speed the processor still functions correctly and
within the published power and thermal specifications.
Workaround: None identified.
Status: For the steppings affected, see the Summary Tables of Changes.
BJ117. The Processor May Not Properly Execute Code Modified Using A
Floating-Point Store
Problem: Under complex internal conditions, a floating-point store used to modify the next
sequential instruction may result in the old instruction being executed instead of the
new instruction.
Implication: Self- or cross-modifying code may not execute as expected. Intel has not observed this
erratum with any commercially available software.
Workaround: None identified. Do not use floating-point stores to modify code.
Status: For the steppings affected, see the Summary Tables of Changes.
