I work in e-waste recycling. Ever since the TurboQuant paper in March, I haven't been able to sell any DDR3. I'm guessing that the DDR2 and 3 this article is referring to is the actual memory chips, not modules/sticks that servers, desktops, laptops, etc. use, because the latter aren't moving.


Yep. Don't expect to sell those sticks on ebay at great price. Those new chips will be likely soldered to appliances like low end routers/APs, set top boxes, various adapters, low end systems, PLCs, IPBX, NVRs and various embedded devices.

I sold 7,2 Kg of DDR1/2/3 sticks two month ago, for gold recovery. As well as expansion cards, hdd PCBs and a few other things. Got about $600 from this.


Did you cut the gold fingers off or "as-is"


Wild guess, but maybe China has something to do with that? They've got a huge "recover->break down/strip->recondition->sell refurbs to manufacturers" industry pipeline that doesn't seem to much exist outside of China.


Indeed, I was lucky that my PC is old enough to use DDR3 sticks, when I decided to upgrade a couple months ago. I think it's still cheaper to max out your RAM than to buy a new PC.


I thought the same until I calculated the cost of running DDR3. We’re at 0.35€/kWh so it adds up fast. Upgrading the motherboard and getting LPDDR4 sticks would be a net positive before the RAM prices soared.


Is it really that significant? We're talking watts difference and over a year maybe 100kWh difference? $35/year?


I don’t recall the exact numbers, and it’s not apples-to-apples but:

We have 4 sticks of DDR3 totalling 24GB. From what I remember, our home server uses about 70kWh/year to drive the memory. Buying 2 sticks of LPDDR4 would bring that down to about 5kWh (?).

At the time, I remember that a new motherboard and a couple of sticks would’ve paid for itself in 3 or 4 years, IIRC.


Maybe you have priced it wrong? I just checked Ebay, a 16GB 12800 Registered ECC module goes for 40-50USD ea. That is crazy! Last year they were like 5 USD each.


Except almost nobody buys them, even last years for 10 bucks each. That's almost useless ECC Reg memory for HPE Gen 8 servers and workstations (from before late 2015 / start of 2016 with the introduction of the Gen9 using DDR4).

ECC unbuffered DIMMs (9 memory chips per side, no reg buffer/controller) is less available, quite widely used on level entry systems and thus costs a lot more even second hand.


Agree. I was buying DDR3 16GB sticks for some laptops at $5/pop on eBay, now $60+ each.


Do you have any links? I remember DDR3 sodimms being maybe $.25-$.50/gb for low capacity (4gb), but 8gb+ sticks were always $.80-1+/gb.


I misremembered, it was $5 for 16GB DDR4 (not DDR3) sticks that I was paying on eBay. That might change the pricing.

Here's one I found in my email:

That's a great price for either, especially for DDR4. Only one stick though, right?


Yeah, I only bought single sticks at a time as I saw good deals on them. I only needed six sticks for three laptops. Just stuck a bunch of low bids and grabbed whatever I could. At the time there were tons going for $5-10 every day. Trying to stick to ones with free postage otherwise the postage would cost as much as the RAM back then.


That’s crazy, I bought a couple trays of DDR3 2 years ago for under $100 each.
