System power-efficiency is crucial for businesses looking to increase their computing strength
to spread the workload without outgrowing their current data center. With the power-efficient AMD
Opteron dual-core processors, increased performance-per-watt improves compute capacity
within the same infrastructure space. By replacing old Opteron processor-based servers with new
x3755 M3 servers using the new power-efficient processors, you can reduce the number of
servers needed by up to 67.5%, with equivalent performance and as much as a 534% power
reduction. Or, you can nearly double the performance in the same space while still saving on
power, when implementing a one-to-one server replacement.
HyperTransport technology is a high-speed, low-latency, point-to-point link, designed to
increase the communication speed between circuits. It permits the fastest possible access to
CPU and memory. The x3755 M3 incorporates the latest version of HyperTransport technology
(3.0) which provides coherent bandwidth (among processors) of up to 6.4 gigatransfers per
second (GTps) and noncoherent bandwidth (between processors and I/O) of up to 5.2GTps. Go

AMD PowerNow! technology with optimized power management dynamically reduces processor
power draw based on workload. This can result in a power savings of up to 55% per processor at
CPU idle.
DDR3
ECC Memory with Chipkill Protection
x3755 M3 servers use registered double data rate III (DDR3) DIMMs and provide Active Memory
features, including advanced Chipkill memory protection, for up to 16X better error correction
than standard ECC memory, and optional online memory sparing. In addition to offering triple
the memory bandwidth of registered DDR2 or fully-buffered memory, DDR3 memory also uses
less energy. DDR2 memory already offered up to 37% lower energy use than fully buffered
memory. Now, a generation later, DDR3 memory is even more efficient, using 10-15% less
energy than DDR2 memory.
The x3755 M3 supports up to 32 RDIMMs (512GB using RDIMMs; 128GB using UDIMMs), with
8 DIMM slots assigned to each processor (four memory channels with two DIMM slots and one
memory controller per channel). Therefore a 2-processor system is limited to 16 DIMMs. Four
processors are required to use all 32 DIMM slots. Memory types supported include single-, dual-,
and quad-rank, 1.5V and energy-efficient 1.35V DIMMs. 1.35V DIMMs consume up to 18% less
energy than 1.5V DIMMs.
