Windsor 5200-X2 HTT question, MSI K9AG2 Neo 2 Digital

So, I recently became interested in overclocking my AMD 5200+, but I'm having trouble locating a place to update the HTT multiplier.

This is the motherboard that I have, and the screen shows images of the BIOS settings in the 'Cell Menu', which seems to be the menu related to overclocking on page 4.

Now, I've been told that the **** will hit the fan if my HTT speed goes higher than 1000MHz. Currently, I'm sitting at about 1140 MHz at a 228 'FSB' speed, and an implied multiplier of 5. Will 'bad things' actually happen? If so, what?

My RAM is the OCZ DDR2-800 5-5-5-12, shown here:

Would the setting for HTT multiplier be on the same 'cell menu' page, as I think that it probably should be? Is anyone familiar with this motherboard and its overclocking?

Any help and/or insight that you can provide will be most appreciated.
