 The joys of oddball configurations.

In 168 pin DIMMs you have 5 volt FPM, 5 and 3.3 volt
EDO and 3.3 volt SDRAM. There may be other
configurations. The 5 volt FPM and EDO have the same
notch configuration, but they're definitely not the
same as any 3.3 volt, and the 3.3 volt EDO and SDRAM
have unique notches.

What is irksome is the prices being asked now for the
5 volt EDO my Powermac 7300 needs. :P Hmmm, just
searched some and found it can support up to a gig
of RAM, but OUCH!

Pretty much covers the biege pci macs, the nasty 4400/7220 included 
while touching on new-world. 72-pin FPM and EDO are more confusing 
since they dont play well together.

FPM or EDO its all treated as FPM, once you get 2 or more the 7300 
will feel better to use. AU$50 per module, you must be able to do 
better than that. ;)

The 5V and 3.3V have different notch configurations but only slightly 
different.  If you aren't paying attention you could damage something 
trying to put the wrong device in.

5 volt EDO my Powermac 7300 needs. :P Hmmm, just

I just checked www.ramseeker.com and it showed 128Mb DIMMs from US 
$18 to US $69 with most being around US $25.  So sure it's more 
expensive than newer stuff but that's hardly surprising.  According 
to www.memoryx.net the 7300 can take either FPM or EDO.  Then again, 
do you really need to max it out???
