Green ATX motherboard with silver CPU cooler, two black memory sticks, 24-pin and 8-pin power connectors

Atermiter

Atermiter AT-X99 Intel motherboard with Xeon E5-2640V3 and 32GB DDR4 REG ECC RAM

SKU CH-QMVW-GY6WJ MPN AT-X99

X99 motherboard paired with an 8-core Xeon E5-2640V3 and 32 GB DDR4 REG ECC memory

  • CPU Socket TypeLGA 2011-v3
  • CPU TypeIntel Core 5th gen (LGA 2011-v3)

Option X99-2640V3-32G 3200Mhz(16GB x 2pcs ECC)

Struck-through versions exist but are not stocked here.

  • Xeon E5-2640V3 delivers 8-core performance for multi-threaded workloads
  • 32 GB DDR4 REG ECC memory protects data integrity in critical tasks
  • X99 chipset on LGA 2011-v3 socket supports scalable Xeon upgrades
  • Four DDR4 slots allow expansion up to 64 GB capacity
  • 24-pin plus 8-pin power inputs provide stable delivery for sustained loads

Ready-to-run Xeon workstation base

This bundle pairs an Atermiter AT-X99 board with a Xeon E5-2640V3 and 32 GB of DDR4 REG ECC memory. The LGA 2011-v3 socket and quad-channel slots arrive populated, so builders can assemble a multi-threaded station without sourcing parts separately.

Compact board with server-grade wiring

The 235 mm by 185 mm PCB fits mid-tower chassis while exposing a 24-pin plus 8-pin power arrangement and a full-length PCI-E x16 slot. Four DDR4 sockets accept REG ECC modules only; mixing with unbuffered desktop RAM is not supported by this design.

Steps up from consumer dual-channel kits

The included 16 GB sticks run at 3200 MHz, though the fitted processor caps the controller at 1866 MHz. Users moving from standard non-ECC dual-channel kits gain error correction and higher capacity headroom for virtualization or rendering workloads.

Questions about this item

What memory speed does the Xeon E5-2640V3 actually run the 3200 MHz DDR4 REG ECC RAM at?

The CPU's memory controller tops out at 1866 MHz, so the included 3200 MHz modules will run at that lower speed.

What are the exact board dimensions and mounting holes for the AT-X99?

The motherboard measures 235 by 185 mm and uses the standard LGA 2011-3 mounting pattern.

How do I install the 24-pin and 8-pin power connectors without bending pins?

Align each connector's keyed notch with the socket, press straight down until the latch clicks, and avoid angling the plug.
