I'm looking to hopefully upgrade my PC's CPU to the "new" line of Bulldozer CPUs by AMD. Right now I'm running a AMD Phenom II x4 3.4 GHz 965 Black Edition processor that uses the AM3 socket on my GIGABYTE 790FXTA-UD5 motherboard. Unfortunately for me, the Bulldozer CPUs required the AM3+ socket. I head somewhere that you could use a Bulldozer CPU in an AM3 socket with a motherboard BIOs flash, but I'm not sure if my board would support it.
So I guess my main question is: Can I upgrade my CPU to a Bulldozer CPU without upgrading my motherboard?
Any help is highly appreciated!
I'd hate to say it, but most likely no. According to http://www.gigabyte.com/products/product-page.aspx?pid=3258#bios
the latest BIOS F3J was released in 2010/10/15. I 'm disinclined to think that your m/b would support either the Bulldozer/Piledriver processor unless a BIOS update is released for it. What you heard is right, as an AM3+ processor would physically fit the AM3 socket but it would be constrained by the BIOS being able to recognise it. ASUS and Gigabyte had released an update for their boards but unfortunately it seems that your particular model isn't supported.
PS: I do hope I'm wrong and that there's more hope left but coming from a similar position with an AM3 board but no BIOS update for AM3+ processors, I can sympathise with your predicament. What's worse, I'm vendor locked to just 7 official options and even further limited to a 95W TDP processor.
