Yes, Sandy Bridge boards fully support DDR3-1600.
The speeds I have available for STOCK clocks on memory:
Plus you can of course mess with the BCLK as well. But with Sandy Bridge its GENERALLY +/- 5MHz. I can't get stable past 105.5MHz BCLK, and I can't even POST under 95MHz at all.

Well not natively. Thats what overclocking is for. Once you raise the FSB, you raise the ram clock. So if you overclock it, then you can get to 1600, or even higher.

FSB and bclk are the same thing in my experience.
Sandy Bridge natively supports almost all DDR3 speeds that are out (only one that's missing is DDR3-2000). And no, you do NOT raise the "FSB" seeing as how there isn't one. And you don't want to raise the BCLK either unless you know what you're doing and are willing to make that risk.

They completely different technically.
FSB is a system interconnect. BCLK is just a clock generator.
I believe with Sandy Bridge, the BCLK has turned into a full system interconnect now (please correct me if I'm wrong). Since the SATA, audio, PCIe lanes, PCI lanes, ethernet...EVERYTHING is tied to the BCLK. Which is why its so sensitive to adjustment.

running it at 1800mhz.
Actually, believe it or not, your Q9550 has nothing to do with what RAM you use. LGA775, the memory controller is on the motherboard. So swapping motherboards is what would allow DDR2 or DDR3 on LGA775. With anything newer than LGA775 though, the memory controller is on the CPU, which is why memory performance is a lot faster with newer CPU's.
