Validation links and privacy on valid.x86.fr
When you run CPU-Z and want to prove your hardware configuration to the world, the built-in validation feature uploads a snapshot of your system to valid.x86.fr. The result is a permanent, shareable URL that anyone can visit to inspect your CPU, motherboard, memory, and more. Validation links are the gold standard for overclocking proof, but they also raise important questions about what personal data you are making public.
This guide explains exactly what a CPU-Z validation contains, when you should use one, when a screenshot is a better choice, and how to protect your privacy along the way.
What is CPU-Z validation?
A CPU-Z validation is a digitally signed report of your hardware configuration, submitted directly from the application. To create one, open CPU-Z and navigate to Tools > Validate (or click the Validate button on the main toolbar). CPU-Z collects a comprehensive snapshot of your system and uploads it to the valid.x86.fr server. In return, you receive a unique URL that serves as tamper-proof evidence of your hardware state at that moment.
The digital signature ensures that no one can alter the reported values after submission, which is why validation links are trusted for competitive overclocking.
What data is exposed
A public validation page displays a thorough inventory of your system. The following details are typically visible to anyone with the link:
- CPU name, family, and stepping — exact processor model, revision, and microcode
- Core clocks and multiplier — base frequency, current frequency, and bus speed
- Mainboard model and chipset — manufacturer, board name, and chipset revision
- BIOS version and date — firmware identifier and release date
- Memory configuration — module count, capacity, frequency, timings, and SPD data
- GPU model — graphics adapter name and driver version
Privacy note
Some motherboard vendors embed serial numbers or asset tags in the BIOS strings that CPU-Z reads. These can appear in your validation. Always review the validation page after submitting to check for unexpected identifiers.
Validation vs screenshots
Both validation links and screenshots can communicate your hardware details, but they serve different purposes. Here is a side-by-side comparison:
Validation link
- Digitally signed and tamper-proof
- Single URL covers all hardware tabs
- Accepted by HWBOT and OC competitions
- Always public once submitted
- Cannot redact individual fields
Screenshot
- Easy to blur or crop sensitive data
- Can be shared privately (email, DMs)
- No account or upload required
- Not cryptographically verified
- May need multiple images for all tabs
When to use validation links
Validation links shine when authenticity matters more than privacy. Common scenarios include:
- Overclocking records — competitions and leaderboards require signed proof of clock speeds
- HWBOT submissions — the platform accepts valid.x86.fr URLs as official evidence
- Benchmark proof — when sharing benchmark scores in forums, a validation link adds credibility
- Quick hardware summaries — one URL replaces half a dozen screenshots
When to prefer screenshots
Screenshots are the safer option when you want control over what others can see:
- Tech support threads — support staff only need specific tabs, and you can crop accordingly
- Privacy-sensitive environments — corporate or enterprise machines may carry identifiable asset tags
- Selective sharing — blur serial numbers, MAC addresses, or any field you prefer to keep private
- Private channels — screenshots can be sent through encrypted messaging without leaving a public trace
Privacy best practices
Whether you use a validation link or a screenshot, follow these guidelines to minimize data exposure:
- Review before sharing — always check the validation page or screenshot for serial numbers, asset tags, and OEM strings
- Blur sensitive fields — use any image editor to obscure serials in screenshots before posting publicly
- Use private channels when possible — if the recipient does not need a public link, send screenshots via DM or email instead
- Limit your audience — only post validation links in trusted communities where the data serves a clear purpose
- Remember permanence — validation links on valid.x86.fr are persistent; assume they will remain accessible indefinitely
Privacy note
Once a validation is submitted, the data is publicly accessible and cannot be edited or deleted by the user. Treat every validation link as permanently public. If your system contains identifiable information in BIOS strings, consider using screenshots with redactions instead.
How to submit a validation
Follow these steps to create your own CPU-Z validation link:
- Download and run CPU-Z — grab the latest version from the download page and launch the application.
- Wait for detection — let CPU-Z finish scanning your hardware. All tabs should be populated before you validate.
- Open the validation dialog — click Tools > Validate in the menu bar, or use the Validate button if visible on the toolbar.
- Submit — click Submit to upload your report. CPU-Z will connect to the valid.x86.fr server and generate your unique URL.
- Copy your link — once the upload completes, copy the URL from the dialog. This is your shareable validation link.
- Review the page — open the link in a browser and verify that no unwanted personal data is displayed.
