Phenom doesn't support DDR2-1066?

[KTE]

I'm aware that JEDEC hasn't even finalized/approved 1066 DDR2 spec yet.
RD 790 chipset supports DDR2-1066 perfectly.
MSI Platinum cannot run 1:2.66 divider which gives DDR2-1066 at stock HT ref for Phenom.
Gigabyte boards run 1:2.66 divider fine with RAM that is not SPD DDR2-1066 prigrammed, so you get DDR2-1066 at stock.

Crucail Ballistix Tracer that I have are not SPD programmed 1066 but EPP 1066 (attached). Like most people.

According to MSI HQ admin Phenom does not support PC2-1066 RAM (stock HT ref) which is not JEDEC approved/finalized. Which means no DDR2-1066 available yet is supported.

How can this be if I've seen people run DDR2-1066?
