Sonnet recommendation to de-interleave RAM in older Macs

Les Dodson was using a Sonnet 350MHz G3 card in a Power Mac 8600 with 128MB of RAM (two 64's in A1/B1 slots). Whenever he ran a Retrospect backup, he kept getting "data miscompare" errors pointing to files - but never the same two files. Dantz's web site made reference to this error and G3 upgrade cards, but the situation described did not fit Les' setup. So he contacted Sonnet Customer Service. They replied: If you have more than 100 MB of RAM (or even if you don't), and it is interleaved, please de-interleave it. Interleaving means that the RAM is arranged in pairs, with matching pairs in slots A1/B1, A2/B2, and so on. To de-interleave, re-arrange your RAM so that the DIMMs in corresponding slots are not the same size. Also try removing the Level 2 cache card from your computer. Note: Interleaving is not an issue in newer Macs (such as G3/BW and G4 Power Macs, as the RAM slots are not paired in any way.
