Common 问题

OCCT 代表 OverClock Checking Tool（超频检测工具）。它是一款适用于 Windows 和 Linux 的免费一体化稳定性测试、压力测试、基准测试与系统监控应用。OCCT 已持续开发超过 20 年，全球下载量超过 7000 万次。

OCCT 用于对计算机硬件进行压力测试、基准测试与监控。它可在高负载下验证 CPU、GPU、RAM 和 PSU 的稳定性，检测过热、电压跌落、频率降频和硬件缺陷。对超频、PC 组装 QA、RMA 诊断和工业 burn-in 测试至关重要。

是的。OCCT 是免费软件。核心稳定性测试、监控、基准测试和证书功能均可免费使用。针对不同专业需求提供多种版本，但基本诊断能力对所有用户免费。

OCCT is designed for gamers and overclocking enthusiasts, custom PC builders, RMA technicians, system administrators, data center operators and industrial computing environments. Anyone who needs definitive proof of rock-solid hardware benefits from OCCT.

OCCT is safe, legitimate diagnostic software. It contains no malware, adware, spyware or hidden payloads. With over 70 million downloads and 20 years of development, OCCT is one of the most trusted stability testing tools available. Always download from the official occt.cc page and verify SHA checksums. See our trust and security policy for full details.

压力测试软件会在低系统层级有意操控 CPU、GPU 和内存，从而触发 antivirus 引擎的启发式误报。这是影响所有硬件诊断工具的行业共知问题。请使用 SHA-256 校验和和数字签名验证下载文件。验证通过后，将 OCCT 添加到排除列表。请参阅我们的antivirus 故障排除指南获取分步说明。

下载 only from the official occt.cc download page. After downloading, compute the SHA-256 hash of the file and compare it to the published checksum. Additionally, right-click the installer, open Properties, and verify the Digital Signatures tab shows the official publisher certificate.

OCCT 是本地硬件诊断工具。测试报告和监控数据存储在您的计算机本地。OCCT 不包含 adware 或数据采集组件。您选择分享的稳定性证书由您自行生成和分发。

For basic hardware checks, 30 minutes per component is a reasonable minimum. For overclock stability certification, run each test for at least 1 hour. Professional PC builders and industrial burn-in processes often run multi-hour or overnight test sequences. Longer tests increase confidence in stability.

OCCT 本身不会损坏正常工作的硬件。但压力测试会将组件推至热力和电气极限。散热不足、组件故障或极端超频可能导致不稳定，在极少数已有缺陷的硬件上可能加速故障。请始终监控温度，并在散热充足的情况下负责任地使用 OCCT。

OCCT offers multiple CPU test algorithms optimized for different detection scenarios. The standard OCCT mode provides the fastest error detection for most use cases. Linpack mode stresses floating-point units more aggressively. Choose based on your checks needs; the standard OCCT mode is recommended for general stability testing.

稳定性证书是可分享的证明，表明您的系统通过了一系列严格的预设测试。PC 组装者将其用于客户交付文档。超频爱好者分享它们以展示已验证的配置。证书包含测试参数、时长和结果，确保完全透明。

是的。OCCT 支持同时并行测试多个 GPU，即使来自不同品牌，且无需连接显示器。非常适合 multi-GPU 工作站、render farms 和无头 GPU burn-in 测试。

是的. OCCT brings its full suite of stability testing, monitoring and benchmarking features to Linux. It is suitable for data centers, embedded systems, high-performance computing and any Linux environment where hardware reliability checks is essential.

Windows 10 或 11（64-bit），现代 x86-64 处理器，至少 4 GB RAM（建议 8 GB+），支持 DirectX 11 的 GPU 用于 3D 测试，OpenCL 1.2+ 用于 compute 测试。Linux 需要 64-bit 发行版及合适的 GPU 驱动。建议管理员或 root 权限以获取完整传感器访问。完整要求请参阅下载页面。

当前稳定的 Windows 版本为 16.1.10.99。OCCT v17 beta 也已发布，包含重大内存测试改版、性能优化和新功能。最新版本和发布详情请访问下载页面。

是的。OCCT 是用于合法硬件测试、诊断和质量保证的合法软件。全球个人、企业和工业运营都在使用。用户必须遵守当地法律，且仅在自有或获授权测试的系统上使用 OCCT。

是的. OCCT is widely used in commercial PC building, prebuilt system QA, RMA technician workflows and industrial burn-in processes. Stability certificates provide professional documentation for customer deliveries and warranty checks.

OCCT must be used ethically for hardware checks and diagnostics on systems you own or are authorized to test. Do not use OCCT to intentionally damage hardware, disrupt services or test systems without permission. Users bear full responsibility for their testing activities. Read the complete policy on our trust and security page.

OCCT 是免费 freeware，以透明方式开发，提供公开发布说明、可验证校验和和开放的开发实践。虽然并非传统意义上的完全 open source，OCCT 通过公布的 checksums、签名二进制文件和持续的公开开发沟通保持透明度。
