I have gigabyte GA-MA74GM-S2 with a 9750 AMD phenom 2.5mgz quad core.I recently got a good deal on an Athlon AM3 which my mobo is compatible for.The speed is faster than my phenom @ 3ghz,would this make my pc faster and would I notice any gains of speed with this cpu or not?I would have to flash my bios to have this cpu compatible with my mother board
Thanks

only you can find out what BIOS the board has............ but I would install the cpu first. if you have problems you can revert back to old and flash it........ i think gigabyte has an auto update tool (software) from it's site......... or included on the software cd that came with the board. fool proof. never had a mishap using it.

I have the bios from the cd and instructions say specifically the bios must be flashed first.Ive also never done a flash bios before (yikes)I have ready if you do it wrong you can kill your board so I may have somebody do it for me.

it is on track. try the new processor without doing a BIOS update. if it works it works.............if it doesn't you need to put the old processor back in and put the newest BIOS on your board............ when you go to the board site ........... read up on all the available BIOS'. you may have to do one or two incrementally.

I know there's an auto update tool. I've used them before.

It isn't an upgrade if your board won't boot because it needs an updated bios for the cpu microcode. The guy who replied is more knowledgeable than you and is only trying to help. As for your question. You need to be more specific. Is it an Athlon or Athlon II? How many cores? What is the specific model? There are literally dozens of models of Athlons and Athlon II's. Just like Phenom's and Phenom II's. Some two core some four core

I had no problem with upgrading from an AMD Athlon II 4850e (AM2) to a AMD Athlon II x4 630 (AM3) on my Dell Optiplex 740 DT edition with the Enhanced BIOS. While I had success there, am not sure it would had been the same in a non-enhanced system.

Oh, and the performance of a true quad core (no H/T) or gimmicks is like the difference between day & night. Windows 7 ran sluggish on the dual core 4850e (an 'energy efficient' CPU), on the 630 x4 is kicking some tail, though one of the specs (I believe HyperTransport) is not at full speed. Still, a true quad is better than a dual core, both operates at about the same frequency. BTW, the 630 x4 was among the first line of AMD quads, the 620 was $99, mine was $10 more, and there were a couple of others.

Gave Intel a run for their money!
