product. The reference use condition differs between workstation and server processor
SKU’s. Implementing processors outside of reference use conditions may affect
reliability performance.
1.1 Processor Features
Table 1-1 provides an overview the Intel Xeon processor 5600 series feature set.
.
The Intel Xeon processor 5600 series support all the existing Streaming SIMD
Extensions 2 (SSE2), Streaming SIMD Extensions 3 (SSE3) and Streaming SIMD
Extensions 4 (SSE4) instructions. Additionally, Intel Xeon processor 5600 series
support Advanced Encryption Standard-New Instructions (AES-NI).
The Intel Xeon processor 5600 series support Direct Cache Access (DCA). DCA enables
supported I/O adapter to pre-fetch data from memory to the processor cache, thereby
avoiding cache misses and improving application response times.
These processors support a maximum physical address size of 40 bits. Also supported
is IA-32e paging which adds support for 1 GB (2
30
) page size in addition to 2 MB and 4
kB page size support for linear to physical address translation.
Finally, these processors support several advanced technologies including Execute
Disable Bit, Intel
®
64 Technology, Enhanced Intel SpeedStep
®
Technology, Intel
®
Virtualization Technology (Intel
®
VT), Intel
®
Hyper-Threading Technology, and Intel
®
Turbo Boost Technology.
1.2 Platform Features
Various new component and platform capabilities are available with the implementation
of Intel Xeon processor 5600 series.
New memory subsystem capabilities include Low Voltage DDR3 (DDR3L) DIMM support
for power optimization. The Intel Xeon processor 5600 series also add features to
provide improved manageability of memory channels. The DDR_THERM2# signal has
been added to support high-temperature DIMMs and their 2X refresh requirements.
