February 21, 2026 - The CPU-Upgrade website will be moved to a new server tomorrow, on Sunday, February 22. The move will start at 8 AM and will take about 2 hours. The new server will have the latest software and about the same hardware. I anticipate minimal downtime during the move.

December 9, 2020 - The CPU-Upgrade.com website will be moved to a new server today (Wednesday, December 9). Our new server will be faster and more responsive. The move will start in the second half of the day. We do not expect any downtime during the move.

June 10, 2020 - The CPU-Upgrade.com now uses https (SSL) protocol to make all connections to the site more secure and safer. If you bookmarked any http:// pages or posted http:// links on other sites we recommend to change them to https:// if possible. However, old http:// bookmarks and links will still work, as our site automatically redirects all http:// requests to SSL-protected pages.

October 26, 2016 - I started cleaning up CPU support data. It's a long and tedious process, which includes correcting CPU family and model names, expanding or fixing CPU features, and confirming processor compatibility by matching CPU and motherboard sockets. The CPU-Upgrade site has more than a million CPU support records, so going through them will take a while. In the end, we should have more accurate CPU information.
