HM55 capable of 200mhz bus? (SLG PLL)

I have a Fujitsu with a P6200 (16x133=2133), HM55 chipset, and SLG PLL.

I understand the HM55 chipset supports ddr3 800/1066, so ram multipliers of 3x and 4x. If I program the spd for 800 only, I should be at 1200 if I run the bus at 200mhz.

Can the HM55 handle 200mhz bus? I'm imagining the cpu can handle 3.2ghz at stock vcore. And the ram is capable of 1333.

I'm trying to sift through the giant pll threads here, but most have to do with ics plls, and it's mostly the core2 platform.

If the HM55 can't handle 200mhz, how about 166?

Linked below is the most comprehensive PLL pinmod I've found using the HM55 chipset where a MSI GX740's PLL is clocked from 133Mhz to 166Mhz then to 200Mhz.

Thanks. I think I stumbled upon that from one of the threads. I just wonder how much he was limited by cpu vs bclk too high.

I suppose I'll do 166 for a while
