However, I have a problem. I don't know if I have K9A2VM-FD or K9A2VM-FIH and I don't know how to find out. I've opened my box and looked at the card, but it only says K9A2VM. By reading the specs and looking at pictures, I know it has to be one of them, or at least that it is not K9A2VM-F V2 since it only has two RAM slots and I have four of them installed. There are other obvious differences too, which I can easily spot by looking at the picture.
Now, looking at the CPU support page for -FD and -FIH, they seem to have differences in what CPUs they support:
-FD at least supports an X6: http://www.msi.com/product/mb/K9A2VM-FD.html#/?div=CPUSupport
Phenom II X6 Thuban HDT90ZFBK6DGR 1090T 200 3.20 3M 6M E0 125 7501v1B.zip
But the -FIH CPU support page is different: http://www.msi.com/product/mb/K9A2VM-FIH.html#/?div=CPUSupport
If I can use that processor, I'm really happy. But -FIH doesn't seem to support Phenom II at all. So provided that the information in the CPU support page is correct, it's fairly important to me to know which model I have. But in case nobody knows how I can distinguish between them; if I buy a Phenom II X6 CPU and it turns out that my motherboard doesn't support it; what is the worst thing that can happen? Will I break the CPU or motherboard, or will it simply not work, but the hardware will still be fine?
