"Overclocking past a max FSB"

ok, so my motherboard in one of my PCs has a 333mhz FSB. I just installed a 2800+ Barton into it (on a GA-7VAXP Rev1.1 Mobo).

Its on an FSB of 334 atm, never exactly on the said FSB as always.

Anyway, on a mobo with a 333mhz FSB, how much further over that could I get? I just raid in PC format I could put a better northbridge cooler on and put the excisting cooler on the southbridge to get further past the max FSB. This work!?

Thanks for any help.

I know that. I just wanted to know how far my new 2800+ would overclock.

Depends what core it is. Palomino core Athlons don't do anything much. T-Bred B cores will do 2.7 GHz in some extreme cases, most having FSBs (RAM permitting) of 200+ MHz.

dunno... probably. I running a 266 XP2000+ at the moment, so I aint got near 166.

Where do you type it in though? Type one higher than 166 then, and you've actually overclocked.

I just type in a number and press enter. Thats my overclocking technique.

Forget about the north and south bridges for a minute. Messing around with the bridge cooling is only done when you are either having stability problems or want that little bit extra. And just cooling the bridges won't make anything faster.

Remember, the DDR speed is 2*FSB. So your FSB is 166 MHz in reality. I don't think the board will do more than this, but I'm not familiar with Gigabytes.

To get a higher FSB, you have to set it higher some how. Some times this is by a jumper on the board that changes between 100, 133, 166, 200 MHz. Some times it is in the BIOS. You may be able to raise the FSB in much smaller increments as well. I don't know for your board.

What I do know though is that just cooling the bridges themselves won't make anything run faster. You need to set it higher for that.

how long is a piece of string? the speed you can get it from raising your front side bus all depends on the memory you are using and how good it is and how good the cpu is at overclocking, Putting a better heatsink and fan on the northbridge and putting the existing one on the southbridge will not really make much differance unless your memory\cpu is able to handle high front side bus's, try it and see what happens.
