Anyone Try crucial 2x1 gig PC3200 ECC with -5B D??

[ilgreco1974]

I would like to buy and try these 2 gig modules with -micron 5b d chips ... these are unbuffered ECC mem modules compatible with my opteron 165 and my Dfi ultra-D but i dont know if should be ok overclocking them because of ECC ...
There is any option to disable ECC from bios for better overcklocking results?
What do you think?
Thanks

i haven't used the ECC ones, but back in april or so, i tested out a normal crucial value 1gb stick that used 5b D, it managed to pull off 263mhz at 3-3-3, 2.9v
