Rent an NVIDIA A40 for 48 GB ECC in proper datacenter form factor. Passive-cooled, NVENC-equipped, ISV-certified — the rack-friendly workstation-class card built for 24/7 batch renders, 34B FP16 inference, Omniverse pipelines, and DreamBooth on SDXL with bit-flip-safe weights. Billed per-minute, paid in BTC, USDT/USDC or CLORE. Server-grade passive thermals for unattended overnight jobs that simply can't tolerate fan failure.
A40 is the workstation-grade 48 GB card — twice the memory of a 3090, all with ECC, all on certified drivers. Mid-tier in price, no-nonsense in production.
Passive cooling, server-rack chassis, no fan-failure surface area — the A40 is the A6000 spec built for 24/7 unattended batch jobs. Render farms, Omniverse pipelines, and SaaS inference tenants prefer this form factor when uptime matters more than NVLink topology.
48 GB is enough for production-scale Houdini scenes, Blender Cycles with full geometry, and 8K video pipelines. OptiX accelerated.
48 GB hosts 13B FP16 + 7B FP16 on the same card with batched serving. ECC catches the bit flips that crash long-running endpoints.
When 24 GB is a constraint and you don't need HBM bandwidth, A40 is the answer. The cheapest path to a single-card 48 GB workstation on the marketplace.

When ECC + datacenter form factor matter and your workload doesn’t need NVLink. A40 is server-rack-friendly (passive cooling, NVENC), A6000 is a workstation card. Same 48 GB ECC, similar bandwidth. A40 is more available in DC fleets, A6000 in studios.
ECC memory catches single-bit errors silently in flight - mandatory for production CAD pipelines, V-Ray and Octane farms, regulated medical or financial ML, and any research where bit-flip integrity affects results. Pro cards (A4000/A5000/A6000/RTX 6000 Ada/A40) also carry ISV certifications consumer cards do not. If your client SLA references ECC or ISV validation, the consumer 4090 disqualifies.
The NVIDIA RTX A-series and RTX 6000 Ada carry full ISV certifications: V-Ray, Octane, SolidWorks, Rhino, DaVinci Resolve, ANSYS, COMSOL, and the Adobe Creative Cloud chain. Consumer Ada cards (4090/5090) are not on those lists. If your renderer's support matrix excludes GeForce, you need a pro card - which is exactly what CLORE.AI lists in this tier.
Yes - the A5000 and A6000 expose NVLink in pairs (no Switch fabric), giving 112 GB/s peer bandwidth and unified memory across two cards (48 GB on A5000 pair, 96 GB on A6000 pair). Filter by 'NVLink' in the marketplace to find listings. The RTX 6000 Ada and A40 do not have NVLink connectors but pair via PCIe with FSDP.
Pro cards (A6000 / RTX 6000 Ada / A40) give you 48 GB ECC at one-quarter to one-third the rental price of an A100 80GB and one-fifth of an H100. You give up HBM bandwidth and FP8 tensor cores, but for production rendering, virtual workstations, and 13B-34B inference under ECC the pro tier hits the price-performance sweet spot.
The cards themselves run cooler and quieter at lower TDP - A4000 is single-slot 140W, A5000 is dual-slot 230W, A6000 is 300W with a blower-style cooler designed for rack airflow. CLORE.AI is a remote rental platform, so the noise question only applies to your own studio if you're hosting; pro cards are explicitly the quieter pick there.
48 GB ECC in datacenter form factor — the rack-friendly cousin of the A6000 for render farms and Omniverse.
Passive cooling and full server-rack form factor — ideal for 24/7 batch render fleets without active fan failure.
