syncmax VC166 PC166 CL2

just got 3 sticks of the above
what does the VC166 stand for and has anyone tried this mem yet?

'VC' is Virtual Channel. I am surprised that you found some, I did not know anyone made tham anymore. They were all the rage back when PC100 was the highest mem spec, they provided about 10% increase in apps. But the motherboard had to support them. I hope yours does!
