Note: This review was from fall 2001 comparing G4/500 vs G3/500 vs G4/400 ZIF CPU upgrades to the original G3/350 CPU in my B&W G3. In 2003 I posted a review comparing the OWC G4/533-550 ZIF (at up to 600MHz) to the Powerlogix G3/800 upgrade as well as including G3/500 and G4/450 comparison tests. The latest reviews are listed at the G3 upgrade reviews page and G4 upgrade reviews page. (Original article text follows) Other World Computing sent review loaners of their G4/500, G4/400 and G3/500 CPU ZIF upgrades. This review compares the performance of the G4/500, G4/400 and G3/500 OWC upgrades in my B&W G3. Results of performance tests with the original G3/350 CPU module are also included for comparison. These ZIF upgrades are also listed as compatible with the XLR8 CarrierZIF cards for owners of CPU Card slot Macs such as the 73-9600 and many clones (see below for a complete list). For more information on the CarrierZIF, see the CPU Cards page for a list of several CarrierZIF reviews and articles. If you're confused about ZIF upgrades with the CarrierZIF see my illustrated Setup Guide to the CarrierZIF for more information and important installation tips. (That guide was written in 1999, using the original CarrierZIF card. XLR8 now offers a smaller/revised "MPe" version.) Although the Mercury ZIFs require motherboard jumper settings changes and come with no printed manual (online install guides are at OWC), the savings compared to some "name brand" upgrades could be used to a) add more RAM or b) add a better video card; therefore addressing two performance areas for the same price as a 'name brand' CPU upgrade alone. If you're not experienced with installing CPU upgrades make sure you read the guides linked on the installation page of this review. Models Reviewed:
For the latest pricing, check OWC's Site Specials page. (Prices lowered again - check the Site specials page for the latest pricing - I think the G4/500 now is near $200 as of April 2002 but check OWC's site for the latest pricing.) Review Table of Contents:
Is an OEM ZIF a Good Fit for You? There are two main things to consider when buying an OEM Jumperless ZIF CPU Upgrade like these.
As mentioned in all my past reviews of G4 CPU upgrades, without software that takes advantage of the Altivec core, a G4 runs most applications no faster than a G3 CPU of the same speed (all other factors being equal). Applications with Altivec support often show dramatic performance increases with a G4 CPU. For a partial list of applications that have G4 Altivec (what Apple calls the 'Velocity Engine'), see the FAQ's Apple G4 topic area.
System Compatibility: The OWC Mercury ZIFs are compatible with the following Mac models:
Using a ZIF socketed card (XLR8 CarrierZIF, CarrierZIF MPe, PowerLogix Zforce) as a base card, you can use the Mercury ZIFs with the following Mac models. (The list below is based on previous info I have, check with the vendor of your carrier card to verify system compatibility.)
* Catalyst based motherboard Macs cannot use G4 CPUs due to a motherboard hardware issue. You can use G3 upgrades in these models however. Other Owner Experiences: Many owners of Other World Computing Mercury ZIFs have posted their ratings, speeds and commenst in my searchable Rate Your G3 Upgrade database. Apple G3 owners should select 'Other World Computing' as the card brand and either Beige or B&W G3 as the Mac model. To see Mercury ZIF reports when used in a CarrierZIF (in older Macs), select 'XLR8 CarrierZIF' as the card brand and look for 'OWC ZIF' next to the CPU speed or in the report comments.
