What type of chips can do Cas 1.0?
I Know BH-5 can do it, but how much voltage needs?

Recently i got it a pair 2x256MB Geil Ultra Plat. PC3500 and with cas 1.0 over 200 Mhz works very well at 2.65V. I choose cas 1.0 with A64 Tweaker. Nevertheless, this memories can boot with cas 3.0, then are not BH-5.

Anybody knows what chip can be?

My system is:
A64 Winchester 3000+, MSI Neo2, PC3500 Geil Ultra Platinum

Thanks!
