stress-test modules
Processor, graphics card, RAM and the card’s VRAM. Every test computes its result twice and compares. A drop in performance is a warning; data that does not match is an error.

Service diagnostics for Windows 10 and 11
All of your service diagnostics in one window.
Instead of ten programs one after another: one file and one button. SybeTool loads the processor, the graphics card and both memories to 100 % at the same time, shows the live temperature and power draw of every component, and saves the results to the USB drive while the test runs. If the laptop dies halfway, the report is still there.
- No installationone EXE file from a USB drive, no account
- Everything at once, one buttonCPU, GPU, RAM and VRAM under full load for the time you set
- Live temperatures and wattshow much power the processor and the card draw every second
- Results saved as it goesthe report stays on the USB drive even if the computer shuts down
- Programs in one clickLenovo Vantage, Dell Update, Chrome, VLC from the vendors’ sites
- Report for the customerPDF and image with the verdict, plus a before/after repair comparison
A road through the program
Four numbers that say what a repair shop gets. Scroll, and the path takes you from the load test to the report.
0
blue-screen codes with their causes
The program reads memory dumps, the event log and Windows reliability history. For every crash it shows the driver at fault when it can be read, and the causes from the most likely one, with instructions on how to confirm it.
Plus 7 crashes without a code: sudden shutdowns, graphics resets, WHEA errors and application crashes.
0
component checks with ranked faults
Quick checks that answer the customer’s usual questions: why the laptop is slow, whether the charger is strong enough, whether the drive is healthy. Every check ends with a list of causes and “how to confirm, what to do”.

EXE file, one report for the customer
No installation, no account, nothing sent anywhere. After the test the program saves the verdict, a PDF, HTML and TXT report and a PNG image to hand to the customer, and for a repair a separate before/after comparison.

That is all it takes per computer. Type the ticket number, choose the duration, press start, collect the verdict.

Prepare
The hardware is recognised automatically: model, serial number, processor, card, memory, drives, battery. You type the ticket and choose the duration.
-
2
Test
Live: temperatures, hotspot, clocks, power draw, fans, a 3D scene and WHEA events from the Windows log. A crash during the test ends up in a recovered report.

Report
Verdict, results table, service recommendations you accept with one click, and the technician’s notes. The report is ready to print.
What the tests check
Each module answers one question: does the component compute correctly under full load. A missing reading is never passed off as a result.
CPU
- Load
- computation on every core, checksums compared with a reference
- An error is
- a wrong computed result, not a drop in performance
- Also measured
- throttling, clocks, power draw, cooler thermal resistance in °C/W
GPU
- Load
- the SybeSphere scene in Direct3D 11, the full-screen 3D City in DirectX 12 with ray tracing, and verified CUDA, DXR and video-decode workloads
- An error is
- a wrong frame or computed result, a driver reset from the log
- Also measured
- hotspot, VRAM, clocks, power draw, temperature limit, FPS
RAM
- Load
- algorithms known from MemTest86: own address, moving inversions, block move, modulo-20, bit fade
- An error is
- a bit that came back different from what was written; the report shows which bits
- Limitation
- tested from inside Windows, without physical addresses; we say so plainly
VRAM
- Load
- patterns written to the card’s memory and checked by the card itself, as in memtest_vulkan
- An error is
- a word read back differently than written, with the address of the first errors
- Also measured
- a short retention test and a CPU-side check of every eighth block
Beyond the stress tests
- Before and after maintenancesame ticket number, the second test is compared with the first; a new fault is never shown as an “improvement”
- Fans and temperaturesfan speeds from the card, the board and the laptop, a temporary boost and curves for the service
- Hardware report and BitLocker keysfull specification from SPD, SMART and NVMe; a copy of the recovery keys before a repair
- Function checkskeyboard with a key map, display, camera, audio, USB ports, Wi-Fi and LAN, Windows Update
- Driver cleaningremoves graphics and audio drivers completely, with a plan of changes and a confirmation, like DDU
- LAN stationswatch and start tests on other computers in the shop network from one place
- Programs and knowledge baseverified vendor installers and an explanation of how to read results and where measurements end
3D City: the graphics card loaded like in a game
New in 0.11.0, selected on the GPU test tab. A full-screen street at night in DirectX 12, built from realistic models of cars, buildings, street lamps and paving. Traffic lights work, cars drive with turning wheels, people cross on green, it rains, and the lights reflect in the puddles. A card with ray tracing traces reflections and shadows with rays. The program loads the card to full power while the processor does very little.
- Image artefactsa control frame rendered off screen and compared tile by tile; an error only when the difference repeats
- Verified ray tracinga ray self-test before the start; the report gives the exact reason when RT is off
- Power and throttlingload up to the power limit; reaching the power limit is information, not a fault
- Driver reset and WHEAonly a real loss of the card, with the reason from Windows; the program keeps running
Captured on a laptop with Intel Iris Plus graphics at full resolution. That card has no hardware ray tracing, so we verified the rays on the Microsoft WARP renderer.
Proof for the customer
Documents the program produces: the before/after maintenance comparison, the test report in portrait and landscape, and the hardware-and-checks report. These are exactly the files SybeTool saves, generated from demonstration data.
The customer report is shown in English; the other documents are shown in Polish. The program writes every document in the language it runs in.
