How can a MoBo that doesn't support DDR2 support an AM2+ cpu???

I have an old Phenom II X4 920 (AM2+) processor and need to upgrade my motherboard.

Searching around, I found the Asus Sabertooth 990FX. Looks great and according to the "CPU Support List", supports my "Phenom II X4 920".

HOWEVER...

According to the "Memory Support List", this board does not support DDR2 memory.

As far as I'm aware, an AM2+ cpu won't work with DDR3 memory, so how can this MoBo claim to support old AM2 processors?

(all attempts to contact Asus via their abysmal website have ended in extreme frustration.)

Asus Sabertooth 990FX supports only AM3 and later chipset processors. It doesnot support a AM2+ processor.

The "920" is an odd-duck, but the CPU Support list includes every X4 from the 805 to the 980 (including the 910 and 925 by name). I rarely find the "920" mentioned specifically.

But that's immaterial. Every Phenom II X4 from the "965" on down is an AM2/AM2+ processor, and the Sabertooth claims to support it.

In this link if you look closely you'll see that at the end of the name of the processor it is written either AM3 or AM3+ chipset.

So it may have been listed wrong but I am sure than am2+ processor cannot be used on a AM3+board.

Thanks. Very weird, but it looks like my 920 fell between the cracks.

I knew I got it cheap for a reason. :)
