CPU Model Gold 6134

  • Four-socket Xeon Gold 6134 CPUs deliver 32 cores at 3.2 GHz base
  • 512 GB DDR4 2666 MHz ECC memory across 16 DIMM slots
  • PERC H730P 2 GB controller supports RAID 0/1/5/6/10/50/60
  • Dual 400 GB SATA SSDs provide fast boot and application storage
  • iDRAC 9 Enterprise plus redundant 1600 W platinum power supplies enable remote management and uptime

Mission-critical compute platform

The Dell PowerEdge R940 is a 3U rack server populated with four Intel Xeon Gold 6134 processors running at 3.2 GHz with a 3.7 GHz turbo frequency. Each CPU provides eight cores, yielding 32 cores and 64 threads across the system. It ships with 512 GB of DDR4 2666 MHz registered ECC memory installed across 16 DIMM slots, leaving 32 slots free for expansion up to 6 TB. A PERC H730P controller with 2 GB cache manages storage, and dual 1600 W platinum power supplies provide redundancy.

Database and virtualisation hosts

This configuration suits organisations running memory-intensive databases, large-scale virtualisation clusters or analytics workloads that benefit from high core counts and large memory capacity. The four-socket design and 48 DIMM slots give headroom for growth. Buyers who need more than eight 2.5-inch drive bays or who require additional network connectivity beyond the provided dual 1 GbE and dual 10 Gb SFP+ ports should evaluate other platforms.

Four-socket scalability ceiling

The defining specification is the maximum of four installed processors, which is already reached in this unit. This means CPU performance cannot be increased by adding sockets; any future compute growth must come from memory expansion, storage changes or a platform migration.

Questions about this item

What rack height and rail kit does the 3U R940 require?

The server occupies 3U of rack space and ships with Dell Ready Rails for square-hole or round-hole cabinets.

How are the four Xeon Gold 6134 processors and 512 GB DDR4 memory installed, and what step is often missed?

All four LGA 3647 sockets are already populated; the 16 registered ECC DIMMs fill 16 of the 48 DDR4 slots, so the common omission is leaving the remaining slots empty instead of balancing them across the four memory controllers.

Which components will need replacement first — the 400 GB SSDs or the 1600 W power supplies?

The two 400 GB SATA SSDs have a finite write-endurance rating and will typically wear out before the redundant 1600 W platinum power supplies, which are hot-swappable and rated for longer service life.
