Intel BV80605001914AG - Processor - 1 x Xeon X3430 User manual

Intel®Xeon™ Processor 3400 Series
Key Features of the Intel®Xeon™ Processor 3400 Series (codenamed “Lynnfield”)
Intel®Core™ Microarchitecture (“Nehalem”)
These processors offer users the benefits of the latest technology –Nehalem architecture –in a single-processor
configuration.
Intel ® Turbo Boost Technology
Turbo Boost delivers additional performance automatically when needed by taking advantage of the processor's
power and thermal headroom. This enables increased performance of both multi-threaded and single-threaded
workloads.
Intel®Hyper-Threading Technology
Hyper-Threading Technology, available with most Xeon 3400 Series processors, allows thread-level parallelism,
resulting in more efficient use of processor resources. With higher processing throughput, you enjoy substantially
improved performance.
Integrated Memory Controller (IMC) with 2 Channels DDR3 Memory
The move to DDR3 memory offers increased performance due to higher memory speeds, and reduced power
consumption compared to FB-DDR2 memory operating at the same speed. The 3400 Series supports up to 4
ECC / Non-ECC UDIMMs or 6 RDIMMs.
Integrated PCI Express I/O
16-lane PCI Express 2 port enables all input/output and manageability functions to be handled by a single chip.
Flexible configuration options include 1x16, 2x8, or 4x4.

Intel®Xeon™ Processor 3400 Series
Platform capability (6 DIMMs):
•Up to 2 channels per CPU
•Up to 3 DIMMs per channel
Memory types supported:
•DDR3 1333, 1066, and 800
•Registered ECC (RDIMM) and Unbuffered ECC (UDIMM)
•Single-rank (SR), dual-rank (DR), quad-rank (QR)
System memory speed (i.e. the speed at which the memory is actually
running) is set by BIOS depending on:
•CPU capability
•DIMM type(s) used (memory speed, U/RDIMM, SR/DR/QR)
•Number of DIMMs populated per channel
Both channels in a system will run at the fastest common frequency:
•Example: If you populate 1 DIMM at 1333 MHz in Channel 1, and 1 DIMM at 1066
MHz in Channel 2, both DIMMs will run at 1066 MHz.

Memory Population Scenarios
Maximum Bandwidth:
●DDR3 1333 across both channels
●2 DIMMs per channel (4 DIMMs)
Maximum Capacity:
●DDR3 800 across both channels
●3 DIMMs per channel (6 DIMMs total)

For maximum bandwidth, you want to fill only 1 DIMM per channel. Since 1333MHz memory is only supported at up to 1 DIMM per
channel, the maximum installation would be 2 DIMMs.
For maximum capacity, you want to be able to install as many DIMMs as possible. Populating 3 DIMMs per channel will result in the
memory running at a maximum of 800MHz, meaning you can choose slower DIMMs, but they must be registered memory.
For systems offering only 4 DIMMs, please contact your Silicon Mechanics sales representative.
