Just to check out the veracity of the amount of AM2 phenom ready mobos being so low, I started to check each manufacturer website to find out what's going on.
In this research, I included only old AM2 motherboard, and release version -not the prerelease-. AM2+ is out of the challenge for obvious reasons. Most of the AM2 needs a bios update, but some AM2 asrocks are phenom compatible out of the box, as asrock has been using old chipsets more recently.
In alphabetical order:
Abit:
1 out of 12 motherboards are Phenom Compatible.
AN-M2HD - Geforce 7050 - uATX
Aopen:
0 out of 1

Gigabyte:
14 out of 17
I just visited each AM2 motherboard at www.gigabyte.com.tw
MSI:
11 out of 28
msi.com.tw -> service -> cpu support.
Sorry if I missed some manufacturers, actually. But lets talk about these contenders I temporary choose for this.
the winners are:
Asrock with 15 AM2 phenom ready mobos.
Gigabyte with 14
Asus with 13
MSI with 11.
In %:
gigabyte has 82% of their AM2 mobos ready for phenom.
Asus 65%
Asrock 60%
MSI 39%
TOTAL (all manufacturers in this test):
59 out of 162 mobos are Phenom ready, that's 36%
TOTAL (only Asus/Asrock/Gigabyte/MSI):
53 out of 90 mobos are Phenom ready, that's 58%
What I see is that the main reason for a motherboard to be incompatible with phenom is the lack of a 4MBit bios. In the case of Asrock alone as example, all incompatible mobos have that single difference face to face with the phenom ready ones. But of course, anyone can recheck if this is the case in all the rest of the manufacturers.
Of course not all the mobos are available, many are just out of stock/discontinued. But the point is that you can always find used ones on ebay or something.
