since the advent of the earliest Pentium processors there has
been a need for older systems (486's in the case mentioned)
to be able to keep up with such speeds. Intel is usually the
one to bring out overdrives specific to their design but as
we moved into the long black board that is slot1 things started
to change. Now instead of overdrives Intel produces budget CPUs
that work with just about any Slot1 or even Slot2 Motherboard,
this has left a gap for Pre-Slot1 systems in need of additional
horsepower. In steps Evergreen Technologies a recognised competitor
in the overdrive department although not one that usually has
had the best performance. In the past Evergreen have had to
use lesser chip designs with their upgrade technology as Intel
already had their own line, however things have changed.
since Intel left the Socket7 scene there has been a gap for
Overdrives to fill and so far nobody has actually tried anything
of any great note. Thankfully Evergreen closely followed by
a couple of other developers (to be covered in future reviews)
has stepped in with their cement truck to fill up the gab. We
were able to get our hands on a Spectra400Mhz which is designed
to upgrade systems right back to the earliest of Pentium CPUs.
Spectra400Mhz is essentially a K6-2-400 CPU from AMD built onto
a small circuitry system, this allows you to adapt to older
voltage and pin designs. Previous Evergreen CPUs have only been
able to boost P75's and upwards to 200Mhz including MMX instructions,
a 400Mhz boost is a massive leap forwards. The difference is
obviously that being a K2-6 CPU you get 3Dnow! Instructions
on-top of existing MMX, in general a more up to date CPU. Included
in this package also comes a CD-ROM filled with bios updates
to get rid of Y2K problems and also make it ready for your CPU.
The CPU itself has 64K of Level1 Cache, is compatible with Socket5,
7 and Super 7 systems, Lifetime Warranty (always good) and a
bus that works at 66Mhz and 100Mhz.
