I have had some probblems with the absolute bottom of the barrell in terms of price ram its generally worth a few extra $ to go up a notch. there is no real need to go all the way though. generally PC133 will run at 100 with no problems. -----Original Message----- From: pic microcontroller discussion list [mailto:PICLIST@MITVMA.MIT.EDU]On Behalf Of Alexander JJ Rice Sent: Thursday, February 26, 2004 9:47 PM To: PICLIST@MITVMA.MIT.EDU Subject: Re: [OT:] PC memory On Wed, 25 Feb 2004 22:27:18 -0500, Anthony Toft wrote: > Being in the market for some more memory in this PC, I looked up the > characteristics and ASUS (the motherboard maker) says that I can use > pc100, memory sellers say pc100 or pc66.

I believe that this _is_ the case - PC100 is a JDEC standard, the only other specification is the CAS which will either be 2 or 3 cycles for PC100 (CL2 gives about 5% better memory badndwidth), additionally PC133 will work quite happily at 100MHz in my experience. Anyone that tells you that the more expensive memory is more 'compatible' is talking rubbish as far as i know. You may well find that it is cheapest to get PC133 CL3 memory and run it as PC100 CL2 memory as PC133 is more recent, or just go down the nearest computer junk shop or swap meet or ebay.
