I want to add more memory into my machine, but... I am not entirely sure what sort of memory comb I should be looking for. My machine is Dell Dimension 4400, and according to Dell's tech specs my memory type is DDR-SDRAM. I've heard of DDR, and of SDRAM, but not of DDR-SDRAM. This is what Dell says:

DDR SDRAM
Memory connectors: two
Memory capacities: 128-, 256-, and 512-MB non-ECC DDR SDRAM
Minimum memory: 128 MB
Maximum memory: 1 GB
Memory type: DDR (non-ECC)


I ran SiSoft Sandra, and it provided the following information about my current memory setup:

System Memory Controller
Location : Mainboard
Error Correction Capability : None
Number of Memory Slots : 2
Maximum Installable Memory : 2GB
DIMM0 - J5G3 : DIMM Synchronous DDR-SDRAM 256MB/64 @ 266Mt/s
DIMM1 - J5G1 : DIMM Synchronous DDR-SDRAM 128MB/64 @ 266Mt/s

Logical/Chipset 1 Memory Banks
Bank 0 : 128MB DDR-SDRAM 2.5-3-3-6CL 1CMD
Bank 1 : 128MB DDR-SDRAM 2.5-3-3-6CL 1CMD
Bank 2 : 128MB DDR-SDRAM 2.5-3-3-6CL 1CMD
Speed : 2x 133MHz (266MHz data rate)
Multiplier : 4/3x
Width : 64-bit
Refresh Rate : 7.80µs
Power Save Mode : No
Fixed Hole Present : No

Memory Module(s)
Memory Module 1 : 256MB 8x(16Mx16) DDR-SDRAM PC2100U-2533-750 (CL2.5 up to 133MHz) (CL2 up to 100MHz)
Memory Module 2 : Samsung M3 68L1713CTL-CB0 25C6A501 128MB 8x(16Mx8) DDR-SDRAM PC2100U-2533-750 (CL2.5 up to 133MHz) (CL2 up to 100MHz)

My question is, what sort of memory can I put into this thing? I've found some pretty cheap memory sticks on eBay, for example 512 MB DDR PC-2100, 184 Pin DIMM, 266 MHz Bus, Unbuffered, Non-Parity, Unregistered. Would this be acceptable? Am I supposed to be looking for DDR sticks or SDRAM sticks?

It's been a long time since I've had to mess with memory, so this is somewhat baffling to me off the bat.
