Do I need to reformat when changing from one CPU Architecture to another. Such as from Phenom 2 x4 945 to a FX-8350

I currently have a ASUS M5A99FX Pro R2.0 MOtherbooard with 16GB of Ripjaws X @ 1866Mhz, a EVGA 9800Gt GPU x2 in SLI, Samsung 840 Pro 256GB x2 in Raid 0, and a Phenom 2 x4 945 CPU cooled by a Corsair H60 in push/pull. Ive been in the process of upgrading for about a month and a half now. I finally got my new CPU in today which is a AMD FX-8350. In the past I have upgreded few CPUs with no problem. However, those upgrades were minimal or maxing out the Mobo's CPU support and usually staying within the same Architecture of CPU. I have never upgraded from one platform to another. Example from Phenom to FX. My question is will it be necessary or even recommended to reformat and re-install Windows . Its not a big deal to do and doesnt take that long but I literally just re-installed about 2 weeks ago when I got in my SSDs. Any help/advice would be greatly appreciated,, Thanks in advance. ~Odizl

Obviously a reinstall after changing out hardware components is preferable, however shouldn't be necessary :)

best to make sure the BIOS that's currently on the board will support the new cpu............... and you should make sure that your board will actually support that cpu.



you need the 1006 BIOS

Yeah but a Windows reinstall shouldn't be necessary

no, you don't need to reinstall the opsys. it's just a cpu swap.

That's what I thought. The board supports the CPU and I already flashed to latest BIOS. I jus wasnt sure if changing the CPU to one that many generations newer could warrant a reinstall you know. Thanks for the speedy reply.
