Hi, I found a bunch of DDR1 modules laying around and I wanted to put them to good use. Will these work together?

1) 1 x 1GB DDR1 PC2100 Kingston Ram (266Mhz)
2) 2 x 512MB DDR1 PC3200 Samsung Ram (400Mhz)
3) 1 x 512MB DDR1 PC3200 Elixtir Ram (400Mhz)

Total = 2.5GB Running @ 266Mhz

Will all four work together? The motherboard supports dual channel, it has 4 DDR DIMM Slots. From the PDF manual I gathered the following, please let me know if my config I want set up will work:


"DDR Population Rules
Install at least one DIMM module on the slots. Each DIMM slot supports up to a
maximum size of 1GB. Users can install either single- or double-sided modules to
meet their own needs. Please note that each DIMM can work respectively for
single-channel DDR, but there are some rules while using dual-channel
DDR (Please refer to the suggested DDR population table on p.2-8). Users may install
memory modules of different type and density on different-channel DDR DIMMs.
However, the same type and density memory modules are necessary
while using dual-channel DDR, or instability may happen.

Please refer to the following table for detailed dual-channel DDR. Other combination
not listed below will function as single-channel DDR.
DIMM1 (Ch A) DIMM2 (Ch A) DIMM3 (Ch B) DIMM4 (Ch B) System Density

128MB~1GB 128MB~1GB 256MB~2GB
128MB~1GB 128MB~1GB 256MB~2GB
128MB~1GB 128MB~1GB 128MB~1GB 128MB~1GB 512MB~4GB"



Thanks!!

I think the dual-channel mode will have to be disabled - assuming it doesn't do that on its own. Other than that, I believe they will work fine as single channel RAM.

And they should all run fine as 266.

As you said, you're trying to make some use of them, not break any speed records.

I'd run memtest86 on them for at least overnight to make sure all is well.
