When you boot at lower memory speeds, the board will tighten the memory timings. Make sure you have active cooling on both your ram and northbridge. Any FSB over 333mhz really needs a fan over the northbridge. I've got an 80mm over mine, with nothing over the ram usually (1.9V doesn't even warm the heatspreaders.) When I bench, I usually bench in sub-freezing ambient temps...

Of course your pi times are going to go down when you set the FSB lower, you have an e6300 therefor the cpu will be clocked slower. You should be aiming for your max fsb (which is around 490?) with the multi set to 2.5x, which would result is a memory speed about 1180.
I have a HR-05 nb heatsink along with an 80mm fan on it, so i am pretty sure the nb is very cool. And while i was testing the memory, i let a 120mm fan sit over the memory.

My max fsb is 522, so you are saying to boot up at lower fsb and not test the memory through booting up in the bios, but rather use setfsb21a to overclock and test the memory in windows? I might give that a try later on today.

i will try to do that also.

thanks hutch, ill let you know if i get any more luck.
