Speccy displays different info than motherboard documentation

I have a GA-890GPA-UD3H rev 2.0 motherboard.

My documentation says it has a 890GX/SB850 chipset. Speccy reports I have a 785GX/SB750.

Ideas? Could other information be reporting different that what the hardware is advertised to be?

I'm using v1.01.132 on W7 Ultimate 32bit.
