## FAQs  
### Q: What processors are compatible with LGA 1366?  
A: LGA 1366 supports Intel's Nehalem and Westmere microarchitecture-based CPUs, including the Core i7-9xx series and Xeon processors for servers.  

### Q: When was LGA 1366 released?  
A: While the exact release date isn't provided in the source material, it was succeeded by LGA 2011-0, which was released in 2011, suggesting LGA 1366 was introduced earlier.  

### Q: What replaced LGA 1366?  
A: LGA 1366 was replaced by LGA 2011-0 for high-end desktops and servers, as well as LGA 1356 and LGA 1567 for specific use cases.  

## Why It Matters  
LGA 1366 marked a significant shift in Intel's CPU socket design, enabling higher performance for high-end desktops and servers. It introduced support for Intel's Nehalem and Westmere architectures, which brought improvements like integrated memory controllers and QuickPath Interconnect (QPI). This socket was pivotal in transitioning from older designs like LGA 775 and LGA 771, paving the way for future advancements in multi-core processing and efficiency. Its legacy lives on in successors like LGA 2011-0, which continued pushing the boundaries of computing power.  

## Notable For  
- Supporting Intel's Nehalem and Westmere microarchitectures, which introduced major performance improvements.  
- Replacing both LGA 775 (desktop) and LGA 771 (server) sockets, unifying high-performance computing under one platform.  
- Being succeeded by multiple sockets (LGA 2011-0, LGA 1356, LGA 1567), reflecting its broad influence.
