Introduction
The RTX 4090 is the reference graphics card in the high-end GPU market, but not all versions are created equal. In recent months, “modified” variants with more VRAM have appeared , designed for those working with artificial intelligence, rendering or very large datasets . Let's see the differences between the original RTX 4090 Turbo 24GB and the Mod 48GB version guaranteed by IlNegoziodiLuserna® , and how to distinguish real OEM cards from unofficial ones .
RTX 4090 Turbo 24GB: The Solid, Proven Foundation
The RTX 4090 Turbo 24GB is an OEM version with a blower design , ideal for compact workstations or multi-GPU servers . This is NVIDIA’s reference configuration : powerful, stable, and optimized for maximum driver support.
Main features:
GPU: NVIDIA AD102 – 5 nm
VRAM: 24 GB GDDR6X (384-bit)
Boost clock: 2520 MHz
TDP: about 450 W
Cooling: Rear-expulsion turbine
Ideal use: Local AI, 3D rendering, compact workstations
💡 Pros: Reliability, stability, OEM warranty.⚠️ Cons: For projects that require large amounts of memory (LLM, 8K rendering), 24 GB can become a limitation.
RTX 4090 Mod 48GB IlNegoziodiLuserna®: More Memory, Same Stability
The 4090 Mod 48GB proposed by IlNegoziodiLuserna® was created to fill that limit. It is an advanced and verified OEM version , not a handcrafted modification : each unit is tested internally and covered by a 12-month Italian warranty .
Main technical specifications:
GPU: NVIDIA AD102
VRAM: 48 GB GDDR6X certified
Clock: identical to the original Turbo
TDP: ~470 W
Cooling: Reinforced industrial turbine
Test: 72h burn-in on TensorFlow, PyTorch, Blender
Real benefits:
+100% memory available for AI and complex 3D
Up to +30% performance in VRAM-saturated loads
Full compatibility with NVIDIA drivers
Warranty and direct assistance in Italy
Traceability and quality control
Why choose the 48GB Mod variant
Ideal for those who:
work with AI models or professional rendering that require a lot of memory,
wants to avoid the cost of workstation GPUs (RTX 6000, A6000, A100),
seek a balance between performance, reliability and price .
Beware of unofficial versions
There are cards on the market labeled “4090 48GB” at low prices. Many are unofficial mods , with:
unvalidated memories
Altered BIOS
no guarantee
unstable performance
➡️ IlNegoziodiLuserna® cards are OEM verified , tested and guaranteed in Italy, with direct technical assistance .

Professional alternatives
For those who require more memory or ECC , there are:
RTX 6000 Ada – 48 GB ECC
NVIDIA A6000 – 48 GB
NVIDIA A100 – 80 GB HBM2e
💡 However, these GPUs cost more than double , while the 4090 Mod 48GB is a more balanced choice for power and budget.
Conclusion
The RTX 4090 Mod 48GB IlNegoziodiLuserna® today represents the best compromise between performance, memory capacity and operational security . Thanks to dual VRAM , certified stability tests and the direct Italian warranty , it is the ideal choice for AI developers , render artists , researchers and professionals working with complex datasets , language models and advanced rendering .
Those looking for maximum power and real reliability without facing the high costs of workstation cards will find the 48GB Mod to be the most balanced and versatile solution on the market.
