You got it. Interleaving is when 2 matching DIMMS (size & type) are placed in corresponding slots (ie. A1 & B1 or A2 & B2 etc.). De-interleaving would involve making sure that corresponding slots (ie. A1 & B1) have two different sized DIMMs. Here are 2 quotes from Ryan Rempel's site concerning memory... 1) "If your computer freezes when you enable the cache, or if you have random freezes later, there are several steps you can take that may improve matters. You can increase the clock ratio for the cache (i.e. slow the cache down). It can also help to de-interleave your memory, if it is interleaved. Removing the original motherboard cache can help (if it is removable)." 2) "There are occasions on which RAM which is fine in Mac OS 9 has problems in Mac OS X. So you can try removing RAM DIMMs to see whether that helps." Troubleshooting can be a pain when your configuration seems as though it should work as it is. But trying things and narrowing down the possible causes of problems has it's rewards when you finally get OS X up and running. I only mentioned the de-interleaving as a precaution, as it is one more thing that may cause a problem. There are speed benefits to having all your RAM interleaved, around 10% or 15% as I recall, so it is preferable providing it doesn't interfere with the OS X installation/operation. Trial and error as they say, try it both ways. -Howie -- SuperMacs is sponsored by <http://lowendmac.com/> and...
