I know you can mix SDRAM in a PC because I have 128MB of PC100 and 256MB of PC133, because PC133 was half the price of PC100. The Motherboard bus speed is 100HMZ, and faster PC133 memory will happily run at the slower PC100 speed. I have not come across a speed mix causing the faster RAM to run at full speed. The only time you will get a problem is trying to run PC100 memory in a 133MHz bus. I thought it was the same with the Mac, so you should be able to mix PC100 and PC133 SDRAM too. Hopefully Mary or Charles will respond to this as they are more up on Mac hardware than I am. Pete
-----Original Message----- From: iMac List [mailto:[EMAIL PROTECTED] On Behalf Of Lauren Sauve Sent: Saturday, 1 May 2004 1:05 PM To: iMac List Subject: Mixing ram of different speeds Hi, I just bought some used ram on ebay to upgrade a 500 Mhz SE iMac. The guy had it in his 400 Mhz iMac. I bought both his Apacer 256 MB pc100 chip and a NCP 512 MB pc133 chip. Then I got an email from somebody who told me that I should not mix these two speeds,as the slower one will keep the faster one from running at top speed and who thenoffered to buy one of the chips off of me. Is this guy correct? Is it bad to mix ram speeds? I presently have 2- 128 chips, but I don't know their speed. What do you experts suggest I do? I was planning on using both the 512 and the 256, and selling or holding onto the 2- 128s. Thanks. Lauren -- The iMac List is sponsored by <http://lowendmac.com/> and...
