Ultimate Upgrade
|
||
|
||
That Baby-Blue ZIF socket you may have seen sprouting like
|
||
mushrooms on 486-based systems boards lately is Intel's latest effort
|
||
at standardizing the upgrade market. But whether you can upgrade your
|
||
system to a Pentium-like CPU may depend up on which blue socket you
|
||
get.
|
||
|
||
Intel, which pioneered the why-sell-one-CPU-to-a-customer-
|
||
when-you-can-sell-two? strategy, developed a kitchen-sink socket that
|
||
system makers can install on system boards. This 238-pin baby-blue
|
||
socket will accept DX2 and OverDrive chips (which are the same
|
||
internally), as well as a derivative 32-bit bus version of the Pentium
|
||
(code named P24T), which won't be available until early 1994. A full
|
||
64-bit bus Pentium system requires a system board overhaul.
|
||
|
||
Intel will actually promote two different blue upgrade
|
||
sockets. A 169-pin version is designed for 486SX-and DX-based systems
|
||
and can't accept the P24T, while the 238-pin version is for DX2
|
||
systems and can take the P24T, but system manufactures don't always
|
||
follow this rule. Zeos International, for example, is shipping the
|
||
238-pin socket in its entire line of desktop systems, from the 486SX-
|
||
25 to the 486DX2-66, and is staying away entirely from the 169-pin
|
||
version.
|
||
|
||
As long as system makers design the memory subsystems to
|
||
support the Pentium, there's no reason why most systems would not be
|
||
able to use the 238-pin socket. While we commend Intel for making
|
||
upgrading easier, why couldn't the company simply color-code the
|
||
sockets for us? Make the blue socket for the OverDrive, and the
|
||
purple socket for Pentium. Is that too difficult?
