Need help about CPU FSB

[remzy]

Hello everyone! I've found an xeon e 5472 for cheap with no need to make cuts on the mobo socket because im thinking about using it in a 775 socket. https://www.willhaben.at/iad/kaufen-und-verkaufen/d/cpu-177946101/
The problem is the my mobo supports only 1333 fsb and this cpu has 1600 fsb. Is that a actual problem? My mobo is ASUS P5G41T-M LX. I've found one site which says that this mobo will support this particular cpu on 775 socket with that little sticker on the bottom of it. I've found that info on this site http://www.delidded.com/lga-771-to-775-adapter/3/#asus searching for my mobo.

You'll have to see what others have done specifically with your board but generally speaking, if you put a 1600mhz FSB chip in a 1333 board and run it at 1333, the 3ghz Xeon will only run at 2.5GHz. Your board may or may not be stable at 400/1600.

Be aware that if you use ANY socket 771 CPU in a 775 socket, you'll need both a pin mod sticker and you'll need to break the tabs off in the socket. You may also need to create a custom BIOS with some added microcode. The few times I tried this, it didn't work, and I ended up with ~$60 wasted in CPUs and stickers that I nowhere near recouped after eBay fees. In retrospect I should've just moved to a newer socket, rather than dumping money into a socket whose best CPU doesn't even meet the minimum requirements for some games and programs now.
