As you say a 4GB DDR3 is around 6*4  =24$
I think I can find 4Gb DDR3 parts around 1.5$ in 10K units, so I need 8*1.5 =12$ worth of DRAM, also the PCB, Passives and EEPROM is around 0.5$, and considering the assembly etc, it would at most take about 2$ too, so the production price is around 15$, it has around 9$ or 30% margin on only 1K modules! of course the higher density Modules and laptop modules with smaller PCB size, has higher margin.
If you manage to produce it for $15 you will have negative margin because nobody with any clue will buy them for $15 in volume. And it's would make way more sense to buy existing stuff at $15 in volume, then resell it in low quantities rather than to produce your own and sell at low qty.
BTW you did not include R&D, test equipment, testing procedure (do you intend to sell them untested?) and shipping expenses.

How about 4GB for $13.80 @ qty of 1 with free shipping included? https://www.aliexpress.com/item/4000418955365.html
Or 8GB for $22.10 ($0.84 shipping for any quantity) https://www.aliexpress.com/item/1005002393607532.html

If you think you can not sell it higher to make a profit, then you simply would not make it, But I think I can find a customer for it.

What's the point in producing your junk RAM with dodgy parts and without expertise and proper testing, when you can buy already produced RAM for less? If you want your own brand of RAM, it makes more sense just slapping your stickers on RAM produced by somebody else.

I've just found a UK asset disposal company offering to trade and public sector buyers, 4GB SODIMM ram at £300 for 200 units. That's as low as CA$2.60 each. I am sure that price could be beaten down. Would it be better to use those labels and rebrand your SODIMM as 'second use' memory? Rather like printer ink carts. Bottom line, you cannot compete with a market that's already becoming saturated with scrap memory.

  • If you can buy it for 4$ on eBay, why design it?*

If you want to make money selling memory, make a clone of the Commodore REU chip and sell 16MB expansions for the Commodore 64 with a passthrough port. You'll get those vintage computing folks excited!
And no, I don't mean a GeoRAM clone: the much more capable Commodore REU.
There's some good money to be made supporting vintage computers.
*Except AC/DC adapters on eBay. Avoid them all!
