the only problem is...
as you start getting higher clocks or fsb's, the LDT can't be maintained...
on my shuttle, i have to drop the LDT to 2.5x when i'm doing 1:1 overclocking above 225 fsb or else the computer won't load windows...

I was thinking actually raise the CPU FSB to 250, keep it at 10x mult and have a 5:4 divider for the ram so the ram will run at stock FSB! What do you think?
that way can I keep LDT at 3? Thanks.

Think of it this way.. the nforce3 has stability issues with it's HTT bus going beyond 700mhz, therefore you can have a 250fsb, but in order to maintain stability, you would have to drop your LDT multiplier (which controls actual HTT speed) to 2.5 or 2 in order to keep your HTT bus under 700mhz. Some boards with voltage mods are capable of 750mhz and some stock nforce3 boards can't even go past 650mhz. It all depends on luck. So far, my GA-K8N Pro won't do anything higher than 232fsb with 3x LDT and it won't even post with 200fsb and 4x LDT. I will try dropping LDT to 2.5 and then try for 275+fsb.

I can run a fsb of 289 but I can't use an LDT of 2.5 with the 5:6 ratio.... I have to drop it to 2x...
anyway...
5:6 ratio Irene... not 5:4

Thanks stardust, now I understand more but just wonder why you get the Gigabyte instead of the Shuttle board. Going back to my original topic, I was wondering which board to buy and these two are the choices I have in mind. Just don't know which one is better, can you tell me why you choose Gigabyte?
