What did we have before Double Data Rate Memory? (DDR)
What did we have before DDR ram in computers?

I believe it was called SDRAM. It ran at sigle stick speeds. DDR ram works twice as fast because both sticks can be accessed simultaniously, hence double the latency.

SDRAM (66 / 100 / 133 Mhz) (Intel Pentium 2 / 3, AMD Slot-A)
RDRAM (Designed for Intel Chipset; had to be installed in pairs)
DDR (266 / 333 / 400 Mhz) (Intel Pentium 3 / 4, AMD Socket-A / Socket-754 AMD64)
DDR2 (533 / 667 / 800 Mhz) (Intel LGA-775, AMD Socket-939 / AM2)
DDR3 (1333 - 3200 Mhz)
DDR4 (2133 - 3400 Mhz)

Generally with DDR, these when installed in proper paired configs; then allow for Dual-Channel Mode (128-bit (twice as much data per read/write cycle); instead of 64-bit Single-Channel)

Yea look up that sort of stuff in Wikipedia; lots of in-depth info

how about the good old edo ram

and the dip ram chips
had good times replacing those and findng out which were bad

Good to see someone else remembers those; what a pain they were.

Now we look "old" for sure... :csgogun::csgohelmet:

and rambus (rdram), that lasted about a year?
0m ram moodules, yay (because all slots had to be filled)

All DDR are also SDRAM (synchonous dynamic as opposite to SRAM - static RAM). Before DDR it was SDR, but noone really used this name.
