Ram Question

[Anubis]

Ok i was on newegg today lookin at the outragus ram prices and i noticed something funny.
Heres what they have

CRUCIAL MICRON 256MB 32x64 PC 2100 DDR RAM - OEM - 78$
CRUCIAL MICRON 256MB 32x72 PC 2100 DDR RAM - OEM - 114$

ok so what the difference between 32v64 and 32x72???? and why does this difference account for 36$ difference in price?

CRUCIAL MICRON 256MB 32x64 PC 2100 DDR RAM - OEM - 78$ = standard PC 2100 DDR RAM
CRUCIAL MICRON 256MB 32x72 PC 2100 DDR RAM - OEM - 114$ = ECC PC 2100 DDR RAM, with Error Correction Capability. (Mainly for servers/ high end workstations). For motherboards that support ECC.
