Dear Jim and Paul: You apparently have forgotten that the 3rd and 4th slots could only be used with registered (buffered) memory. Since buffering adds 1 cycle to both RAS and CAS, registered PC2100 has a CAS of 3 or 3.5 not 2 or 2.5. In addition it is more expensive as it is normally sold in the higher densities (registered DDR will have up to 1GB per stick). Given these two factors, most OEMs and resellers probably are asking for only the two slots that can be used with unbuffered (normal) PC2100 CAS 2 memory (or slower) and leave off the expense of 4 slots and testing for 4 registered DIMMs (probably a highly used option on those boards that go both ways). For those who want it (workstations and servers), the ones with 4 slots are available (for a higher price of course). i820 couldn't work in some configurations and that is why it was dropped. Besides, 2GB configurations are unavailable for any RAMBUS boards out there (including i840 and i850). Whereas 4GB AMD760 solutions do exist. So do not confuse an option taken by buyers to an option required by bad engineering. Pete

Jim, <Your point is good except for one thing. Intel had to dumpster thousands of motherboards made before they figured this out.> Good thing Intel did. Now AMD can learn from Intel's mistake and pull off the exact same workaround with DDR 1.5 years after Intel did with RDRAM. Tenchusatsu
