Realtek Generic vs. OEM Drivers: What’s the Difference?
When you search for a Realtek audio driver for Windows 11 24H2, you’ll usually find two options; Generic and OEM (Original Equipment Manufacturer) drivers. Both come from Realtek but serve slightly different purposes. Knowing which one to install can make the difference between crystal-clear audio and no sound at all.
- Generic Drivers (from Realtek’s site):
Work for most systems, great for DIY PCs or motherboards without brand support.
- OEM Drivers (from Dell, HP, Lenovo, etc.):
Customized for your exact model. Recommended for laptops or branded desktops.
Which One Should You Choose?
| Scenario | Best Choice | Why |
| You have a laptop or branded desktop | OEM Driver | Includes manufacturer’s sound optimizations and tools. |
| You built your own PC (custom motherboard) | Realtek Generic Driver | Offers the latest universal updates and fixes. |
| Your OEM hasn’t released a 24H2 driver yet | Realtek Generic Driver (temporary) | Works as a fallback until official support is released. |
| You’re troubleshooting audio issues | Try Generic First, Then OEM Reinstall | Helps isolate whether the issue is driver- or system-related. |
Expert Tip: The Safe Upgrade Order
When updating to Windows 11 24H2:
- Check your manufacturer’s support site first for updated OEM audio drivers.
- If no 24H2-compatible driver is available, download the latest generic Realtek UAD driver from Realtek’s official site.
Tip: Always prefer OEM drivers first. Only use generic ones if your manufacturer hasn’t released a 24H2 compatible version yet.
