Question about DDR RAM

I am holding out for the Asus A7M266-D (anyone know when it is coming out). At any rate, I will be buying a gig of PC2100 (4x256Mb) soon before prices inevitably go up. At any rate, I am pretty sure that I have heard that with DDR mobos if you use more than two DIMMs you have to use registered DIMMs. Is this because of signal noise? Can anyone confirm this? I just want to know before I go out and buy a gig of RAM. Thanks in advance.
 
Depends on mobo. Read up on the one you got, and see what the reviewes found. My board only has 2 slots, so nothin to research.
 
wait, I am talking about the A7M266-D (Dual). Asus will not release a server/workstation dual board with only 2 DIMMs. I know that the A7M266 has 2 DIMMs but I rather doubt that the Dual version has only 2 DIMMs. Correct me if I am wrong.
 
That's okay. I was about to say, the MSI K7D Master (their dualie) even has 4 DIMMs and everyone is based on the Tyan reference design. Oh well, so what about register memory. 😉
 
I too am waiting for THIS mobo ...

XBit Labs reports ...



<< We learned a few additional details about the recently announced dual-Socket A mainboard from ASUS ? A7M266D. Just like ABIT and Gigabyte, ASUS will build its mainboard on the next chipset version in AMD-760MP family ? AMD-760MPX, which will provide the support for PCI64.

This board will have two Sockets A supporting 200/266MHz Athlon and Duron CPUs and 4 DDR DIMM slots supporting up to 4GB PC1600/PC2100 DDR SDRAM. ASUS decided not to follow in TYAN?s footsteps and made its solution support not only registered but also unbuffered DDR DIMM modules. In general, unlike TYAN, ASUS targets its mainboard not for Rack servers but for workstations and power users that is why A7M266D won?t have such a thing as bent DIMM slots, for instance. For the same reason such things as Ultra160 SCSI and 3Com LAN controllers are also optional for ASUS mainboard. Note that they may be implemented on an additional ASUS LS-module, which should be installed into a special ASUS proprietary slot similar to those we saw on some other mainboards from ASUS. Besides this slot, there is also 1 AGP Pro slot, 2 PCI64 slots, 2 66MHz PCI64 slots and 3 32bit PCI slots. Also there will be integrated 6-channel sound by C-media.

ASUS is planning to start shipping this mainboard together with dual-Socket A mainboards by other manufacturers, i.e. in August 2001.
