Ok, I know the times, and I know the difference between edo and fpm, but what about modules with chips on both sides vs modules with chips on just one side? What about modules that only have 2 or 4 chips, vs modules with several small chips?
Take a look at my blog: http://rikintosh.blogspot.com

I avoid those 2 chip/4 chip EDO. The chip density on them is often a problem with many chipsets/boards where they error but 8 chip do not..so I stick with 8 chip (per side) EDO.
But it does depend on the motherboard, some can handle those high density chip simms.... they also work fine with low density chip simms. I just do not want the hassle 😀

2/4 chips EDO modules are usually very low capacity (4-8Mb) and absolutely fine to use even on EDO aware 486 motherboards.
I must be some kind of standard: the anonymous gangbanger of the 21st century.
As with anything relating to memory, don't trust in rules of thumb but actually look up specs of mem controller (usually motherboard chipset in this era) and chips on the SIMMs.
One year's 'high density ' is next year's 'low density', and even overall SIMM sizes aren't always conclusive.
The only rule that is as universal as you can get is that an odd number of chips indicates a parity module. Even is usually non-parity unless chips of different type are mixed.

Yeah, about that universal rule...
It's not. 😀
you're right though on the "Even is usually non-parity unless chips of different type are mixed"
Right to repair is fundamental. You own it, you're allowed to fix it.
