Ooooook. I just recently picked up an AMD Phenom II X6 1090T Black Edition processor, which is a Socket AM3 processor, which I was told was compatible with an AM2 socket.. I currently have an AMD Phenom X4 9500 processor, which is an AM2+ socket processor.
Looking around, it seems that AM3 processors are usually compatible with AM2 and AM2+ sockets, just needing a BIOS update sometimes. I connected the processor but low and behold it doesn't power up (the heat-fan spins and the comp makes all the beep noises and power seems to be on, but the power button just flashes and the monitor won't work). I have been tearing my hair out trying to find an appropriate BIOS update that will make my Socket AM2 compatible, but for the life of me I can't find any, and quite frankly I don't understand any of the documents describing how to "flash" your system and such.
So I need some help finding this BIOS update, if it even exists, and on how to install it correctly. Here's my CPU-Z stuff.
You got me quite excited when I saw the post on Google search because I have the same problem, but turns out your problem might be unsolved. I recently purchased an AMD 1090T as well for my Gateway RS780 motherboard, however it doesn't boot with the new processor. If you find a way around it, please let me know how you did it! Thanks!
From the look of things, there is no way. Gateway responded and said there was no bios update for the motherboard, and I doubt they plan to create one. You will just have to get a new motherboard like I have to. No more gateway comps for me.
