What RAM is compatible with Xeon E5-2640 v3



What is the Xeon E5-2640 v3 Processor?

The Xeon E5-2640 v3 is a server-grade central processing unit (CPU) manufactured by Intel. It belongs to the "Haswell-EP" family of processors and was released in September 2014 as part of Intel's Xeon E5 v3 series.

The Xeon E5-2640 v3 is designed for use in dual-socket server configurations, which means it is intended to be installed in servers with two processors to provide enhanced computing power and performance for server workloads. This processor is suitable for various server applications, such as virtualization, data analytics, database management, and other demanding tasks where multi-core performance and reliability are crucial.

What RAM is compatible with Xeon E5-2640 v3?

The Xeon E5-2640 v3 processor supports DDR4 memory. Specifically, it supports DDR4 ECC (Error Correcting Code) Registered (RDIMM) and Load-Reduced (LRDIMM) memory modules. The ECC feature is important for server-grade processors like the Xeon E5 series because it helps to detect and correct errors in memory, enhancing system stability and reliability.

When choosing RAM for the Xeon E5-2640 v3, make sure to select DDR4 RDIMM or LRDIMM modules that meet the following specifications:

  1. Type: DDR4 RDIMM or LRDIMM (ECC)
  2. Speed: The processor supports various DDR4 memory speeds, including 2133 MHz, 2400 MHz, and 2666 MHz. It's essential to check the maximum supported speed for your specific Xeon E5-2640 v3 model. The maximum supported memory speed will typically be listed in the processor's official specifications or the motherboard's manual.

For example, if your Xeon E5-2640 v3 supports a maximum memory speed of 2400 MHz, you should get DDR4 RDIMM or LRDIMM modules with a speed of 2400 MHz or lower.

  1. Capacity: The processor supports different memory capacities, ranging from smaller modules like 4GB or 8GB to larger ones like 16GB, 32GB, and even 64GB per module. The maximum supported memory capacity will also depend on the motherboard and the number of memory slots available.

  2. Voltage: DDR4 memory typically operates at 1.2 volts (V).

To ensure compatibility and optimal performance, it's always a good idea to consult the motherboard's manual and refer to the official specifications of the Xeon E5-2640 v3 processor when selecting RAM for your system. Additionally, you can check the memory compatibility list on the motherboard manufacturer's website to see a list of tested and verified compatible memory modules.


1.How many cores does E5-2640 v3 have?

The Intel Xeon E5-2640 v3 processor has 8 cores.

2.Does Xeon E5 support DDR4?

The Intel Xeon E5 processors do support DDR4 memory, but not all models in the E5 series have DDR4 memory support. The introduction of DDR4 memory support was introduced with the "Haswell-EP" generation of Xeon E5 processors.
