The price is higher for the new 72-pin 1Mg/4Mg SIMM packaging that
Dell uses for it's 325D/333D 386 machines and above. From Dell, 1Mgx9
SIMM is $99. 4Mg is $595. Part of the price is not only the packaging
but tighter specs. These parts call out a Total Row Access time (TRAC)
of 80ns and a Total Column Access time (TCAC) of 20ns. This latter
spec is the deciding factor.
Most SIMMs are priced on the TRAC number. The TCAC can vary from
40ns to almost 80ns depending on the manufacturer. The higher the
TCAC the lower the price in most cases.
BTW, Kingston makes the 72pin SIMM modules for the Dell machines. I
purchased 2Mg at $99 a piece. The 4mg went for $407. Both from this
local vendor:
Memory Expanders (800) 999-7389
