The Umax "C" series represented the low end of Umax's lineup. Also in the C series were the C500's which also sported the same 603e processor as the C600's. The C500's, however, used a less expandable desktop form factor. The C600's had plenty of room for expansion with 4 free internal drive bays. Other offerings from Umax included the higher powered "J" and "S" series. The C600x/240 was the first in the "C" series to sport Umax's (then) revolutionary cache doubler card. The cache doubler card featured a 1MB cache which communicated with the processor at 80MHz, twice the rate of the 40MHz system bus. The presence of the inline cache boosted processor performance by 26% over the straight C600/240. The cache doubler card sits in the ZIF slot, between the logic board and the processor. Even with this innovative processor design the C600x/240 still featured only 1MB of VRAM which could not be expanded. Those wanting to use a larger monitor and/or higher resolutions would have to spring for an extra graphics card to operate at a reasonable color depth. Like its predecessors, the C600x/240 lacked on-board Ethernet. The internal CD-ROM was a respectable 12x, sufficient to run the bundled software and meet most user's needs quite nicely.

There are currently two different G3 upgrade paths for this machine, one via the ZIF slot and the other via the L2 Cache slot. Currently Newer Technology uses the L2 Cache and MacTell uses the ZIF slot. This poses an interesting question, is one option preferable over the other? Assuming you had two cards that are equal in all other respects (speed, ratio, cache size etc.) which would you choose? Visit our Discussion Board and tell us your thoughts on the matter... Whichever upgrade you choose it will, of course, render the cache doubler card useless and will probably conflict with it unless removed.

Below you will find the MacBench 4.0 results for most of the processor upgrades available for this machine. These results are what the individual manufactures publish for their cards. In other words the speed trials were run by the manufacturer. For an independent evaluation of these cards check the Processor Upgrade Page to see if we have results available. The bar graphs below express results as a percentage of improvement over the base machine, which receives a score of 100%. Further down the page you will find a table with the actual MacBench score.
