I just got an Albatron KM18G Pro mATX motherboard based on the NForce 2 IGP chipset. I removed the northbridge heatsink/fan to replace the thermal pad with white goop and found that the northbridge was the older A3 stepping, not the newer C0 that supports 200MHz bus. WCPUID identifies it at as an A2 but the chip says A3, I have no clue what the difference is.

From what I have read this chip should not be able to get past 180MHz or so. Strangly I was able to run my new 1.4GHz Applebred at a 200MHz bus speed in the BIOS. I need to replace the PC2700 with PC3200 today and see if I can boot into Windows at a 200MHz bus.

So what are your highest overclocks with an A2 or A3 NForce 2 IGP chipset? I was not expencting this much of an overclock due to the stepping and was just curoius what others were getting.
