trick fall Posted October 24, 2001 Share Posted October 24, 2001 Hey guys I'm running an AGP 450mhz G4 and I just bought 512 megs of ram from 0WC. I have 256megs already that are PC100. OWC sent me PC 133 and claim that it's totally compatible and wont give me any problems. Is this bs or what?

Dylan Posted October 24, 2001 Share Posted October 24, 2001 Most PC 133 DIMMS will automatically run at 100MHz when put in a system that has a motherboard that only supports 100MHz RAM, and/or RAM that is already present in the system that is running at 100MHz. -Dylan Link to comment Share on other sites More sharing options...

trick fall Posted October 25, 2001 Author Share Posted October 25, 2001 See, not that's the thing. I have two 128meg strips that are 100mhz. Though I did put the ram in this evening and so far so good. Though I've only really surfed the net. Link to comment Share on other sites More sharing options...
AudioMaverick Posted October 25, 2001 Share Posted October 25, 2001 In general, you should not have any difficulty mixing the RAM as you did. But, with prices as they are, I'd still suggest you get matching memory... if only to satisfy the mind. Some history... The really big issue with the clock rates is not getting memory rated as twice as fast. PC133 SDRAM will not work well in a 66MHz system, such as a Celeron. And, PC150 SDRAM (really exists) may cause intermittent timing issues. Faster memory will literally clock data out the other side too fast for the system. You send in a stream of data, and by the time the system expects the first one to come out, the second is already there. But, the latency introduced by the RAM you bought should be fine. Usually, technicians like to put the larger memory in the first socket. But, in the case of mixing memory speeds, the slower RAM usually goes first. "It's all about the... um-m-m, uh-h-h..."

Chip McDonald Posted October 25, 2001 Share Posted October 25, 2001 You can mix it, but you may have "intermittant" glitches seemingly unatributable to anything.... ... and if you're really concerned, don't mix brands. If you really, really want to be sure don't mix runs, either - check the chips and make sure they're from the same place and appear to have been made at the same time. ------------------ [b]New and Improved Music Soon:[/b] http://www.mp3.com/chipmcdonald Guitar Lessons in Augusta Georgia: www.chipmcdonald.com Eccentric blog: https://chipmcdonaldblog.blogspot.com/ / "big ass windbag" - Bruce Swedien Link to comment Share on other sites More sharing options...
