if the new 1.8ghz g5 is dual....then why does it max out at 4gb of ram?? whats the deal?

The new 1.8 G5s only have 4 RAM slots, the original ones had 8.

Speculation is that they might support 2GB sticks (therefore 8GB total). I don't know if this is confirmed either way.

RAM Expansion

The main logic board of the Power Mac G5 computer has 4 or 8 slots of DDR SDRAM expansion for unbuffered DDR400 (PC3200) dual in-line memory modules (DIMMs) for a maximum memory of 4 GB or 8 GB.

Each DIMM can contain 256 and 512 MB (also is capable of 128 MB, 1 GB, and has future expansion ability of 2 GB) of double data rate synchronous dynamic RAM (DDR SDRAM). At least one pair of the RAM expansion slots contains factory installed DIMMs. The Power Mac G5 supports CAS latencies of 2, 2.5, 3, 4, and 5.

Additional DIMMs must be installed in the slots in pairs of the same size. The slot pairs are numbered as indicated in Figure 4-1 and Figure 4-2. When installing additional memory, populate starting with the lowest slot pair numbers. The combined memory of all of the DIMMs installed is configured as a contiguous array of memory.

don't think it's cause of 2gb chips. its just a selling point. the new 1.8 is also the new low end. its just anothe factor to seperate it from the middle and high end machines.
