AI answer:
The Dell Precision T5810 is a workstation that was released before Windows 11 was announced, and as such, it's not officially supported by Dell for Windows 11. The main hurdles you'll face are:
Processor Compatibility: The T5810 typically uses Intel Xeon E5-1600 v3/v4 or E5-2600 v3/v4 processors. While some of the v4 (Broadwell-EP) processors might technically meet the core/speed requirements, they are generally not on Microsoft's official list of supported CPUs for Windows 11.
TPM 2.0: The T5810 likely shipped with TPM 1.2. However, Dell does provide a firmware update to upgrade it to TPM 2.0. This is a crucial step if you want to install Windows 11.
UEFI and Secure Boot: The T5810 supports UEFI boot mode and Secure Boot, which are required for Windows 11. These settings can be enabled in the BIOS.
Can you run Windows 11 on it?
Yes, it is often possible, but it will be an unsupported installation. Many users have successfully installed Windows 11 on Dell T5810s by taking the following steps:
Update the BIOS: Ensure your T5810's BIOS is updated to the latest version available from Dell.
Update TPM Firmware: Upgrade your TPM from 1.2 to 2.0 using the Dell TPM 2.0 Firmware Update Utility.
Enable UEFI and Secure Boot: Configure your BIOS to use UEFI boot mode and enable Secure Boot.
Bypass CPU Check (if necessary): Since the CPU is likely unsupported, you might need to use methods to bypass the Windows 11 CPU compatibility check during installation. This often involves creating a modified ISO or using registry tweaks during the setup process.
What are the potential downsides of an unsupported installation?
No Official Support: Microsoft and Dell will not officially support your Windows 11 installation on this hardware. This means if you encounter issues, you might have limited or no support.
Driver Issues: You might experience missing drivers for some components, especially chipset drivers, as Dell may not provide Windows 11 specific drivers for this older model. You might have to rely on Windows 10 drivers or generic drivers, which may not always work perfectly.
Future Updates: While many unsupported installations receive Windows 11 updates initially, there's no guarantee that future major updates will continue to install without further workarounds.
Stability: While many users report good stability, there's a slight risk of unforeseen issues or performance quirks due to the unofficial nature of the installation.
In summary: While the Dell T5810 is not officially supported for Windows 11, it's often possible to install and run it with some configuration changes and potential workarounds for the CPU check. Be aware of the potential for limited support and possible driver challenges. If you need a fully supported Windows 11 experience, a newer workstation would be recommended.
