AM3+ cpu on a AM2+ motherboard ( with DDR3 controller )

post #1 of 32
Thread Starter 
So.. My motherboard is AsRock N68C-S UCC. I currently have on it a Phenom II x4 955, 8Gb RAM DDR3 and a HD7770 gpu. The motherboard can also use ddr2, but i never used the ddr2.
Will AM3+ CPUs work on my motherboard since i have ddr3 support ? I'm asking in a theoretical way, i don't want to consult the supported cpu list. I know that AM3 motherboards support AM3+ CPUs.
I want to get a AMD FX-8320 3.5GHz, vishera core (not the bulldozer). I know that AM3+ motherboards are like 40 Euros, but i don't want to get a new one.

No it will not. There are missing features that will not allow the chip to work. If you had consulted the CPU support list, which you are for some reason reluctant to do, you would know that it is not compatible. If it is not on that list it will not work. Not to mention that board doesn't support over 95w CPUs.

You need a new board.

I said in my first post that i don't care about the Supported CPU List. This is more of a theoretical discussion.

There is no theory. If the BIOS doesn't support it it won't run. If it's not on the Supported CPU list it will not run. As I said there are missing features on AM2+ which are required for AM3+.

I'm talking in a tehnical way. Let's asume that the BIOS support AM3+ CPUs, what would then be the missing features ? An AM3 motherboard will support am3+ cpus, why won't an am2+ supprt it? The am2+ has every feature of an am3 motherboard: ddr3, am3 cpus support etc.

Let's talk in general and not about my motherboard specifically.

I am not sure exactly on the missing features but the chipsets are not capable of supporting AM3+ CPUs and it simply will not work. AMD does not release info on why, all we know for sure is that it does not and will not ever work. It's not the outward features that are missing but the internal ones which are used to communicate with the CPU that will cause issues.

But the BIOS cannot support AM3+ because the hardware does not have the necessary features to support it. Not to mention, on your board, an 8350 would probably blow the VRMs right off the board. I don't know what you're trying to figure out. There is no way to get an AM3+ CPU working on an AM2+ board. If it was AM3 then maybe, depending on manufacturer support, but not an AM2+.

actually, if the cpu is on a similar socket, there is a 50/50 chance it will run.

I once ran an LGA775 Intel dualcore E5300 wolfdale on an ancient 775 Pentium IV motherboard.
the board only supported up to Pentium D 820 but it detected the E5300. Although its performance was slower than normal.

Anyway I wouldnt suggest that you do this andrej, because I only did it to test whether the board or cpu was killed by its faulty PSU.

I think what he's really asking is do the FX-Series processors have a DDR2 controller. If they did - they could technically run in a AM2+ motherboard. But they do not. AM3 processors work on AM2+ because they have a DDR2 and DDR3 controller in them. So really the best you could hope to work in a AM2+ motherboard would be a Phenom II X6. Most AM2+ boards only have BIOS support for the first wave of AM3 processors (Phenom II 955 x4, Phenom II 720 x3, Phenom 550 x2, ect)

So yes the board needs BIOS support for the processor but there are several forums where people will actually mod a BIOS file for you and add the CPU support. Flash at your own risk though!

It MAY work on that board with a modded BIOS BECAUSE it has DDR3 slots on it! You could try getting a modded BIOS worked out then test it.

This... I'm running an FX-8350 on a CIVF that does not have this chip on any support list and an AM3+ chip on an AM3 board never was supported by AMD yet it works flawless.
