APPLICATIONS
How our cards are used
The same hardware that handled production AI workloads in data centres — within the budgets of start-ups and laboratories.
Training and fine-tuning
Tensor cores and HBM2 memory for training your own models and fine-tuning open models.
Production inference
Cards with INT8 acceleration for serving models with low power consumption relative to performance.
HPC and simulations
FP64 performance for scientific computing, simulations and data processing.
Laboratories and universities
Build research and teaching systems without the cost of new data-centre accelerators.
GPU TECHNICAL QUALIFICATION
Qualification certificate — a 6-stage test for every unit
Every unit undergoes individual technical qualification before it can be offered for sale. Qualification comprises six stages and uses server-grade tools (nvidia-smi, cuda_memtest, gpu-burn). Each card includes a printed certificate with its serial number and actual measurement results.
Technical fingerprint
Unit identifiers and conformity with the stated model.
Memory
Full VRAM test — 0 errors required.
Burn-in
600 s at full load with temperature monitoring.
ECC
No uncorrectable errors after load testing.
PCIe interface
Link speed and bus errors under load.
Computational correctness
Verification of results in FP32 and FP16 modes.

Full test procedure on our blogVOLUME DISCOUNTS
Larger orders, better terms
We offer volume discounts tailored to your order — in response to an inquiry, after confirming unit availability.
Scale matters
We tailor terms to the order size — individual units and a complete node are priced differently.
Quote on request
Tell us which cards you need and how many. We will send a quote with a price applicable to the entire order.
Availability and lead time
If the full quantity is in stock, we can fulfil the order immediately. We source and quote for any shortfall in response to your inquiry — we always state the lead time.
We do not use discount codes or promotional price lists — each inquiry is quoted individually.

FREQUENTLY ASKED QUESTIONS
Before you send an inquiry
Do you sell to private individuals?
No. We sell exclusively to businesses (B2B), with a VAT invoice bearing the buyer's Polish tax identification number (NIP).
Are you buying privately or looking for individual units?

What does GPU technical qualification cover?
Qualification comprises six stages: the unit’s technical fingerprint, a full VRAM test, burn-in — 600 seconds in the gpu-burn test at full core and memory load, ECC error checks, a PCIe interface test and verification of computational correctness. A card is offered for sale only with a PASS result. A certificate with the qualification results is supplied with the hardware. Read about all 6 stages of used GPU qualification.
Do the cards require a special chassis?
Yes. These are server accelerators with passive cooling — they require a chassis with forced airflow and 8-pin EPS power. A dedicated cooling kit is required in a workstation.
What warranty is provided for used hardware?
We provide a 3-month warranty as standard. If a different period is stated for a particular model, the period in its specification applies. The qualification certificate forms part of the unit’s documentation and serves as a reference when making a claim.
Can I order a larger quantity than shown in the product listing?
Yes — please send an inquiry for larger volumes. We will confirm availability, lead time and pricing terms individually.
