Silver 4U rackmount barebone server chassis with front drive bays and redundant power supplies

ASRock Rack

ASRock Rack 4U8G-GNR2/RF barebone server dual LGA 4710 8 GPU 2700W

SKU CH-J2EQ-04ARS MPN 4U8G-GNR2/RF

4U barebone supporting dual LGA 4710 Xeon processors with eight full-height PCIe 5.0 x16 GPU slots and 2700W Titanium power supply

  • Enhanced airflow cools 600W GPUs and accelerators reliably
  • Dual LGA 4710 sockets support Xeon 6700P, 6500P and 6700E series
  • 80-PLUS Titanium 2700W 3+1 CRPS delivers redundant power
  • 16+16 DIMM slots accept DDR5 RDIMM and MRDIMM
  • 8 full-height PCIe 5.0 x16 slots for dual-slot cards

Dual-socket LGA 4710 barebone for 8 GPU workloads

The 4U chassis holds two Intel Xeon 6700P, 6500P or 6700E processors and eight full-height dual-slot PCIe 5.0 x16 slots rated for 600 W cards. It targets compute clusters that need dense accelerator capacity in a standard rack. Buyers who need more than eight GPUs or single-socket simplicity should look elsewhere.

3+1 redundant 2700 W Titanium power supplies

Four hot-swap 2.5-inch NVMe bays run at PCIe 5.0 x4, or the cage can be swapped for twenty-four hot-swap SATA/SAS bays when a RAID or HBA card is added. One M.2 PCIe 5.0 x4 slot is also provided. The redundant PSU arrangement keeps the system running if one unit fails.

Enhanced airflow design

Optimised internal airflow moves heat away from high-power GPUs and accelerator cards in continuous operation. The board exposes thirty-two DIMM sockets supporting DDR5 RDIMM and MRDIMM in a two-DIMM-per-channel layout. One extra full-height PCIe 5.0 x16 slot and one PCIe 5.0 x8 slot remain for networking or storage expansion.

Questions about this item

How often will the 80-PLUS Titanium 2700W CRPS units need replacement in continuous operation?

The 3+1 redundant 2700W power supplies are hot-swappable; a failed module can be replaced without shutting the server down.

Which component hits its limit first when all eight 600W GPUs run sustained workloads?

The enhanced airflow design is built to cool eight 600W GPUs continuously, so thermal headroom is the primary limit under full load.

What noise and heat levels should I expect when the system runs 24/7 with dual Xeon 6700-series CPUs and eight GPUs?

Redundant cooling targets 600W per GPU slot; expect data-centre noise levels and significant exhaust heat requiring proper rack ventilation.
