Silver 2U rackmount barebone server with eight front drive bays and redundant power supplies

ASRock Rack

ASRock Rack 2U4G8E-EGS2 barebone server 2U dual socket 16 DIMM 8 NVMe 4 GPU

SKU CH-RJ0E-91DQE MPN 2U4G8E-EGS2

A 2U rackmount barebone server supporting dual Xeon processors, 16 DDR5 DIMM slots, eight 2.5-inch NVMe bays, two SATA bays, four full-height PCIe 5.0 x16 slots for GPUs, two OCP NIC 3.0 slots.

  • Dual 4th Gen Xeon CPUs scale heavy workloads
  • 16 DDR5 slots enable massive memory capacity
  • Eight 2.5 NVMe bays deliver PCIe5.0 storage speed
  • Four full-height PCIe5.0 x16 slots fit 4 GPUs
  • Redundant 2700W CRPS power ensures continuous uptime

2U GPU barebone for dual Xeon builds

This 2U rackmount barebone accepts dual 4th Gen Intel Xeon Scalable processors in LGA 4677 sockets. It targets teams deploying dense GPU compute or storage nodes in standard racks. Builders who need single-socket economy or tower-form-factor footprints should look elsewhere.

Redundant 2700W CRPS and direct PCIe5.0 airflow

A 1+1 2700W CRPS supply feeds the chassis, with hot-swap replacement for uptime. Four full-height full-length PCIe5.0 x16 slots draw air front-to-back across GPU coolers. Eight hot-swap 2.5 NVMe bays and two hot-swap 2.5 SATA bays sit in the same airflow path. IPMI remote management lets operators monitor thermals and power without a local console.

Sixteen DDR5 slots and dual OCP 3.0 mezzanines

The C741 chipset exposes 16 DIMM positions at 2DPC for DDR5 RDIMM or RDIMM-3DS modules. Two OCP NIC 3.0 slots at PCIe5.0 x16 add high-speed networking without consuming GPU slots. Two M.2 connectors at PCIe4.0 x4 provide boot or cache devices. No rails, cables or operating-system licences are included in the barebone package.

Questions about this item

How do I install the four full-height PCIe 5.0 x16 GPUs in the 2U chassis?

Remove the top cover, align each GPU with the four full-height PCIe 5.0 x16 slots, press firmly until the retention bracket clicks, then secure the bracket screws. The step people miss is connecting all required 12VHPWR or 8-pin power cables from the 1+1 2700W CRPS units before closing the chassis.

Which components will need replacement first during long-term operation?

The 1+1 2700W CRPS power supplies and the system fans are the primary field-replaceable units. Drive bays support hot-swap 2.5-inch NVMe and SATA drives, so storage can be swapped without downtime. DIMMs and CPUs are socketed but rarely replaced unless capacity or processor requirements change.

What thermal or power limit appears first when all four GPUs run sustained workloads?

The shared 2700W redundant power budget and the 2U airflow path become the limiting factors. With four full-height GPUs and dual Xeon processors drawing continuous load, the power supplies and cooling capacity reach their design ceiling before the PCIe 5.0 x16 links or the C741 chipset do.
