Have a look at the picture at this URL -- this is an :example of Micron's memory. : :http://images.micron.com/images/products/meetsorbeats2.gif : :Anyhow, if the ram dosn't function at PC133, get it replaced. : :- James I found a nice page describing drams. http://www.imagiq.com/RAMGuide.html In anycase, the Micron chips on these defective SDRAM simms are -75's, which means 7.5ns which == 133 MHz. But as the above guide indicates, that does not necessarily mean that the chips are PC133 compliant. When I lookup the part number, aka 48LC32M8A2-75, I get this (for example): http://www.wiredzone.com/items.asp?cartid=&cc=ME-SDRAM In the above list the SamSung part is specified at PC100, but if you go down to the Micron section their 48LC32M8A2 part is specified at PC133. So I'm inclined not to blame IDot. The chips do indeed appears to be PC133, or at least they are supposed to be. I'll get IDot to replace them. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
