Dual Xeon Gold 6148 Tower

This HP Z8 G4 workstation pairs two 20-core Intel Xeon Gold 6148 processors at 2.40 GHz with 16GB of DDR4 memory and an NVIDIA RTX 5000 GPU. The tower chassis targets professionals running complex simulations, large-scale data analysis, or high-resolution video editing workloads.

Upgrade from single-socket systems

Moving from a single-processor platform doubles the core count to 40 threads and unlocks the Intel C622 chipset's full memory capacity of 3TB across 24 DIMM slots. The jump is worth it when render queues, simulation jobs, or dataset sizes exceed the memory bandwidth and parallel throughput of a single-socket machine.

2TB NVMe and 16GB VRAM headroom

The installed 2TB NVMe drive provides fast local storage for active project files, while the RTX 5000's 16GB video memory handles large textures and GPU-accelerated compute tasks. Memory-intensive workloads that exceed 16GB system RAM will require populating additional DDR4 slots to avoid paging bottlenecks.

Perguntas sobre este artigo

What size M.2 NVMe slot does the 2280 drive use?

The installed 2TB NVMe drive uses the M.2 2280 form factor and plugs directly into the motherboard.

How are the two Xeon Gold 6148 processors installed, and what step is often missed?

Both LGA 3647 sockets are populated; the common mistake is skipping the specific torque sequence for the CPU carrier screws.

When the 16GB DDR4 PC4-2666 memory needs expanding, what is the maximum capacity?

The system supports up to 3TB across 24 DIMM slots using registered DDR4 modules.
