Industry Applications
Technical Overview
Two Ada Lovelace RTX 4090 cards deliver a combined 48GB of GDDR6X and 32,768 CUDA cores, linked through the Threadripper PRO 7975WX's 128 PCIe 5.0 lanes on the WRX90 platform. The 32-core, 64-thread Zen 4 processor pairs with 256GB of registered ECC DDR5 for sustained, error-checked workstation reliability.

Frequently Asked Questions
What scale of LLM can this fine-tune locally?
With 48GB of aggregate VRAM and model-parallel frameworks, it handles full fine-tuning of models in the 13B range and parameter-efficient (LoRA/QLoRA) tuning of substantially larger models entirely on-prem.
Why Threadripper PRO instead of a consumer CPU?
Its 128 PCIe 5.0 lanes give both 4090s full x16 bandwidth plus high-speed storage and networking, and ECC memory protects long-running jobs from silent data corruption.
Is this suitable for regulated, on-premises data?
Yes; keeping training fully local supports data-sovereignty and compliance needs in finance, healthcare, and government where sensitive datasets cannot leave the premises.
