Interesting story here. I email Abit regarding the 1T issue. Look what they respond :
Good day, Sir
Thank you for choosing ABIT products!
Regarding this case(can't OC to 250), due to LDT value is a transfer rate between AMD Platform and Northbridge Chipset. The default value is setting 200 x 5 =1000. So when FSB is setting at 250 x 5 =1250. It is over the chipset's limitation.
So in BIOS please refer this setting:
1.CPU FSB to 250
2.DDR frequency:333 -> indicate CPU:RAM -> 6:5
3.LDT set 4x
you can add some voltages on CPU & DRAM
