HP Workstations · Z-Series
The HP Z4 G4 is HP’s single-socket Z-series tower, built around Intel’s LGA2066 platform. Unlike its dual-socket siblings (Z6 G4 and Z8 G4), the Z4 G4 puts all its performance into one CPU socket — making it an efficient, budget-focused entry point into professional-grade CAD, engineering, and content-creation workstations. TekBoost stocks the Z4 G4 configure-to-order, refurbished and functionally tested, with your choice of three CPU-platform configurations so you can match your build to the CPU generation your software and budget actually need.

Choose Your Platform
The Z4 G4 isn’t one fixed spec sheet — TekBoost offers it in three CPU-platform configurations, and each one changes what CPUs, memory, and ECC support you get. Pick the platform that matches your workload, not just your budget.
| Xeon W-2100 | Xeon W-2200 | Core X-Series | |
|---|---|---|---|
| Socket | LGA2066 | LGA2066 | LGA2066 (Intel X299 chipset) |
| CPU options at TekBoost | W-2123 to W-2195 (8 SKUs) | W-2223 to W-2295 (8 SKUs) | i9-9820X to i9-10980XE (4 SKUs) |
| Cores (max) | Up to 18 (W-2195) | Up to 18 (W-2295) | Up to 18 (i9-10980XE) |
| ECC memory | Yes, Registered ECC | Yes, Registered ECC | No |
| DIMM slots | 8 × DDR4 | 8 × DDR4 | 8 × DDR4 |
| Max memory* | Up to 256GB (8×32GB Registered DIMM) | Up to 512GB (8×64GB Registered DIMM) | 256GB |
| PCIe slots | 2× Gen3 x16, 2× Gen3 x4, 1× Gen3 x8 | 2× Gen3 x16, 2× Gen3 x4, 1× Gen3 x8 | Varies by CPU — up to 2× Gen3 x16 |
| TekBoost configuration upcharge | Included (base) | +$99 | +$149 |
*Per HP’s official QuickSpecs documentation for the Z4 G4, 64GB Registered DIMMs are qualified only on Intel Xeon W-2200 family processors. That’s why practical maximum memory differs between the W-2100 and W-2200 platforms even though both share the same 8-slot DDR4 layout.

Professional Graphics & Expansion
The Z4 G4 chassis is built to carry serious GPU horsepower for CAD, visualization, and content-creation work. Per HP’s official documentation, the chassis supports up to two graphics cards across its PCIe x16 slots — dual-GPU configurations require the 750W or 1000W power supply (the base 465W tier supports a single card). TekBoost’s configurator offers professional NVIDIA Quadro (M- and P-series), Quadro RTX, and RTX A-series cards, plus consumer-class GeForce RTX 30-series options for teams that want gaming-adjacent rendering performance on a budget. All three power supply tiers — 465W, 750W, and 1000W — are genuine HP factory options for this chassis. Storage is configurable with a mix of SSD and HDD bays, and networking can be upgraded with Intel or Broadcom 1GbE/10GbE adapters at build time.
Built And Tested Before It Ships
Every TekBoost Z4 G4 is inspected, configured to your exact specification, and functionally tested before it leaves our facility. Every build includes a 3-year TekBoost warranty standard, with a 5-year extended option available at checkout.
How The Z4 G4 Compares
| Model | Sockets | Starting price | Best for | Configure |
|---|---|---|---|---|
| HP Z2 Tower G9 | Single | $949.00 | Compact single-CPU workstation with current-gen Intel platform | Configure → |
| HP Z4 G4 | Single | $299.00 | Budget-focused CAD, drafting, and engineering — this page | Configure → |
| HP Z6 G4 | Dual | $299.00 | Rendering, simulation, larger assemblies needing more cores/RAM | Configure → |
| HP Z8 G4 | Dual | $999.00 | Maximum core count, heaviest professional workloads | Configure → |
The core trade-off versus the Z6 G4 and Z8 G4: the Z4 G4 gives up a second CPU socket (and the Z6/Z8’s higher DIMM counts) in exchange for a lower entry price and a smaller footprint — a good fit when your software scales more with single-core clock speed and GPU performance than with raw core count across two sockets.
Frequently Asked Questions
What’s the difference between the Z4 G4’s Xeon W-2100, Xeon W-2200, and Core X-series builds?
TekBoost offers the Z4 G4 in three CPU-platform configurations. The Xeon W-2100 and W-2200 configurations both support Registered ECC DDR4 memory; per HP’s official documentation, 64GB Registered DIMMs are qualified only on the Xeon W-2200 platform, which is why practical max memory differs between the two (see the platform table above). The Core X-series configuration uses HEDT Core i9 processors instead of Xeon and does not support ECC memory, per HP’s own published specifications.
Is the HP Z4 G4 a single-CPU or dual-CPU workstation?
Single-CPU (single-socket) only. If your workload benefits from a second processor, see the dual-socket HP Z6 G4 or HP Z8 G4 instead.
How much RAM can the HP Z4 G4 hold?
All three platforms have 8 DDR4 DIMM slots, but practical maximums differ. Per HP’s official QuickSpecs, the Xeon W-2100 configuration supports up to 256GB (8×32GB Registered DIMMs), the Xeon W-2200 configuration supports up to 512GB (8×64GB Registered DIMMs — HP qualifies 64GB DIMMs on the W-2200 platform only), and the Core X-series configuration supports up to 256GB.
Does the HP Z4 G4 support dual graphics cards?
Yes. Per HP’s official documentation, the Z4 G4 chassis supports two graphics cards across its PCIe x16 slots. Dual-GPU configurations require the 750W or 1000W power supply — the base 465W tier supports a single card. Tell us your target GPU pair when you request a quote and we’ll confirm compatibility for your exact build.
Is the HP Z4 G4 a good workstation for AutoCAD or Revit?
Yes — see our full guide to choosing a CAD/BIM workstation, where the Z4 G4 is recommended as a strong single-CPU platform for CAD, drafting, architecture, and engineering applications.
Does the HP Z4 G4 support Windows 11?
Builds on the Xeon W-2100 and W-2200 platforms are generally Windows 11 compatible; exact eligibility can depend on TPM and firmware configuration on a given unit. Ask us to confirm compatibility for your specific configuration before you order.
