FSB Limits on Intel 845E chipset

Ram and CPU FSB allowances can bottleneck a system, what about the FSB speed rating of a chipset? My chipset is rated to handle either a 400Mhz or 533Mhz Northwood CPU and only 266Mhz ram. Right now I am running the FSB at 133 pushing the CPU to 2.4Ghz and my ram FSB to 354Mhz. My ram is rated to run at up to 433Mhz so I know the ram is cool, but what about the mother board? The 845E chipset says that it only accepts 266Mhz pipeline for the ram, could I damage the motherboard by running the ram at 354Mhz or higher? System is stable and temps are cool.

Any advice is appreciated, I have searched the net but haven't found any 845E setups with the ram pushed so high.

My Setup:
CPU - 1.8 P4 400Mhz Northwood
Ram - PC3500 DDR433 CL2.5 PNY 512x2
MoBo - Gigabyte 8IEXP 845E Chipset
 
My Abit-BD7-II-Raid which uses the same chipset runs flawlessly 24/7 at 150MHz FSB. Unfortunately due to my Winbond CH5 memory and the problems it has with dividers it wont run 3:4 ratio for the memory. However as soon as I put in one of my Winbond BH5 sticks it will run 150MHz FSB / DDR400 all day long at 2-2-2-5.

Its very unlikely you'll damage anything by running the RAM using the 3:4 ratio, you'll just get higher performance, which is always a plus :)
 
When the 848/865/875 boards first hit the market, I remember seeing Asus release a few 845 boards that were rated for 800MHz FSB usage. I never used any, though ...
