As long as all the SIMMs are at least the minimum speed for the machine you're putting them in, speed is not significant. You can put different speeds in different banks, or mix speeds within a bank, without any problem. (However, you need to make sure all the SIMMs within a bank are the same *density* (e.g. 1M or 256K), and in all Macs prior to the IIci, if you have different density SIMMs in different banks, the higher-density SIMMs must be in bank A.) -- ====== jeanne a. e. devoto ======================================== jdevoto@apple.com | You may not distribute this article under a jdevoto@well.UUCP | compilation copyright without my permission. ___________________________________________________________________ Apple Computer and I are not authorized | CI$: 72411,165 to speak for each other. | AppleLink: SQA.TEST
