Your computer uses 1066 MHz and 1333Mhz DDR3 unbuffered or registered ECC SDRAM memory. DDR3 SDRAM, or double-data-rate three synchronous
dynamic random access memory, is a random access memory technology. It is a part of the SDRAM family of technologies, which is one of many DRAM (dynamic
random access memory) implementations, and is an evolutionary improvement over its predecessor, DDR2 SDRAM.
The primary benefit of DDR3 SDRAM is its ability to run its I/O bus at four times the speed of the memory cells it contains, thus enabling faster bus speeds and
higher peak throughputs than earlier technologies. This is achieved at the cost of higher latency. Also, the DDR3 standard allows for chip capacities of 512
megabit to 8 gigabit, effectively enabling memory modules of maximum 16 gigabyte in size.
DDR3 memory comes with a promise of a power consumption reduction of 30% compared to current commercial DDR2 modules due to DDR3’s 1.5 V supply
voltage. This supply voltage works well with the 90 nm fabrication technology used for most DDR3 chips. Some manufacturers further propose to use "dual-
gate" transistors to reduce leakage of current.
The main benefit of DDR3 comes from the higher bandwidth made possible by DDR3’s 8 bit deep prefetch buffer, whereas DDR2’s is 4 bits, and DDR’s is 2 bits
deep.

Memory Subsystem
The memory subsystem consists of three DDR3 memory channels attached to each processor. All single-processor configurations have six DIMM slots (two per
channel) attached to the primary processor located on the system board. Dual-processor configurations require an optional riser card that contains the
secondary processor and the DIMMs associated with the secondary processor. There are six DIMM slots on the riser, for a total of twelve DIMMs in the system.
Memory Slots
There are six memory slots on the system board. The slots are numbered DIMM1 through DIMM6. DIMM1 is furthest from the processor.
In addition, the dual-processor riser features three additional memory slots. The slots are numbered DIMM1 through DIMM3. DIMM1 is furthest from the
processor.

NOTE: If more than one Quad rank DIMM is installed within a channel (DIMM1 & DIMM4, DIMM2 & DIMM5, DIMM3 & DIMM6) then the maximum DDR3
speed is reduced to 800 MHz. Spreading Quad Rank memory modules across multiple channels is recommended.
NOTE: DDR3 DIMMs have 240 pins, the same number as DDR2, and are the same size, but are electrically incompatible and have a different key notch
location.
DIMM slot configuration for a single processor or a second processor on the riser.

Memory Population Rules
Your computer requires DIMMs within a channel to be populated starting with the DIMMs farthest from the processor first. This means the DIMM slots 1, 2 and
3 must be populated before DIMM slots 4, 5 and 6. In addition, when populating a Quad-rank DIMM with a Single-or Dual-rank DIMM in the same channel, the
Quad-rank DIMM must be populated farthest from the CPU.
To maximize available memory bandwidth, DIMMs within a configuration should generally be spread across as many channels as possible before populating
multiple DIMMs per channel. The population guidelines below help to achieve this.
Single CPU configurations (6 DIMM slots on MB)
lIf configuration contains DIMMs of all the same size, populate in the following order: DIMM1, DIMM2, DIMM3, DIMM4, DIMM5, DIMM6
lIf configuration contains DIMMs of mixed sizes, populate the larger DIMMs first. For example, for a 4GB configuration consisting of one 2GB DIMM and two
1GB DIMMs, the population would be DIMM1=2GB, DIMM2=1GB, DIMM3=1GB, DIMM4=empty, DIMM5=empty, DIMM6=empty.
Dual CPU configurations (6 DIMM slots on MB plus 3 DIMM slots on Riser)
lIf configuration contains DIMMs of all the same size, populate in the following order: MB_DIMM1, Riser_DIMM1, MB_DIMM2, Riser_DIMM2, MB_DIMM3,
Riser_DIMM3, MB_DIMM4, MB_DIMM5, MB_DIMM6.
lIf configuration contains DIMMs of mixed sizes, populate the larger DIMMs in the Riser.

NOTE: If any DIMMs are >30mm tall (possible early 16GB DIMMs), they must be installed on the system board only.

When errors occur during a boot routine that cannot be reported on the monitor, the computer may emit a beep code that identifies the problem. The beep
code is a pattern of sounds: for example, one beep followed by a second beep, then followed by a burst of three beeps (code 1-1-3) means that the computer
was unable to read the data in nonvolatile random-access memory (NVRAM). If the system loses power and beeps constantly when you turn it back on, the
