Waiting for DDR5 to get cheaper means waiting past 2026. One Samsung DDR5-5600 16GB stick costs about five times what it did a year ago on Danawa, Korea’s main price comparison site, and TrendForce says PC memory supply could shrink in 2027. If your PC is broken or the memory is soldered, buy now. Otherwise, check that you’re really short before choosing either way: when my dev PC ran out of memory, the fix was two WSL2 settings, not new RAM.

I kept 32GB and changed two settings
In mid-September, a Gradle build in WSL2 on my Windows dev PC died with five containers running. dmesg showed “Out of memory: Killed process” next to java.
That evening I priced an upgrade from 32GB to 64GB. The PC uses a Gigabyte A620M GAMING X with four DIMM slots, and two hold 16GB sticks; Task Manager’s memory tab shows “Slots used: 2 of 4”. Filling the empty pair was the cheaper option, and I dropped it: four sticks usually can’t hold the EXPO 5600 speed my 7800X3D runs at now, and new sticks may not match the old ones.
That left pulling both sticks and buying two 32GB ones at about ₩750,000 each, over ₩1.5 million in total. A roundup post put the same stick a year earlier at about ₩160,000, so the pair would have cost about ₩320,000 then, by my math.
I closed the tab and looked for the cause instead. WSL2 gives its VM 50% of host memory by default, 16GB in my case, plus swap equal to 25% of host memory, per Microsoft Learn. I set memory=22GB and swap=8GB under [wsl2] in %UserProfile%\.wslconfig, ran wsl --shutdown, and the build passed. It took about an hour.

From mid-September to early November, no build was killed and dmesg logged no out-of-memory event. I keep five containers or fewer and shut down everything but the database during a Gradle build. Swap is there for emergencies, and free -h shows it barely touched.
My other machine is an Ubuntu workstation with an RTX 4090 and 64GB of DDR5-5600 (2×32GB), bought around March 2024 for ₩220,000–250,000 combined. On that workstation, channel layout matters more to me than capacity, because system RAM only comes into play when a local model spills past the GPU’s 24GB of VRAM.
Fourteen months of prices and forecasts
Waiting only pays if the line turns. Here is what happened to it, with the forecasts made along the way. The retail prices come from Danawa’s lowest-price history; the older points were posted by Korean buyers on Naver blogs and cafes, so they’re their purchases, not mine.
| Date | What happened | Source |
|---|---|---|
| 2025-08-11 | Forecast: DDR5 to fall in early 2026 | Digitimes |
| 2025-09 | 16GB stick at ₩69,246 | Danawa via Naver blog |
| 2026-01 | Korean “RAM price” searches peak | Naver DataLab |
| 2026-06 (end) | 16GB at ₩324,900 | Danawa via Naver cafe |
| 2026-09 | 16GB at ₩349,910, 5.1x in a year | Danawa via Naver blog |
| 2026-09-30 | Forecast: contract prices +10–15% in Q4 | TrendForce |
| 2026-10-26 | 16GB at ₩349,500 | Danawa, checked directly |
| 2026-10-29 | 32GB at ₩790,970, same as Oct 18 | Danawa, checked directly |
| 2026-11-07 | 32GB at ₩788,020 | Danawa, checked directly |

The early-2026 drop Digitimes expected never came; the price roughly quintupled instead. Since the end of June the 16GB stick has added only 7.6%, and the 32GB stick dipped 0.4% in nine days.
Naver DataLab’s relative index for 램가격 (“RAM price”) and two related terms went from 100 at that January peak to 9 by October. Prices didn’t fall in between, so I read that as fatigue, not relief.
Europe looks similar. Germany’s 3DCenter index puts DDR5 kits at 5.6 times their July 2025 level, and a 32GB DDR5-6000 kit starts at €447, per overclocking.com on October 19, 2026.
Supply points the wrong way for 2027
Memory makers shifted production to HBM and server DRAM for AI, so PC DDR5 gets what is left. TrendForce says PC DRAM supply could decline in 2027 as capacity moves to servers.
Contract price is what PC makers and module brands pay chip makers, and retail follows it with a lag. That is why shelf prices keep creeping up after headlines say the gains are “cooling.”
China’s CXMT adding capacity is the downside risk mentioned most, though nobody puts a date on it. Nor is DDR6 a way out: JEDEC hasn’t published a final desktop DDR6 standard, and TrendForce reported on May 5, 2026 that commercialization may start in 2028–29, servers first.
The guesses for “back to normal” run years out. AMD’s David McAfee said DDR5 should take about two years to normalize (Wccftech, June 9, 2026). A Barclays forecast points to 2029, and an SK hynix executive mentioned 2030, per overclocking.com. After the Digitimes miss, I treat all of these as guesses.
When I would buy now
Buy now if the machine is broken, you need it for work, or the memory is soldered. Otherwise wait, but plan in quarters, not weeks, and first check memory pressure and swap.
| Your situation | What I’d do |
|---|---|
| PC broken or new build needed | Buy what you need now |
| Buying a Mac or soldered-RAM laptop | Choose memory now |
| 16GB or 32GB that feels short | Check the real cause first |
| Desktop you can upgrade later | Wait, set a price trigger |
| Tight budget, one 16GB stick | Accept single-channel until the pair |
Checking the cause takes a minute. On Windows, open Task Manager’s memory tab for slots used and speed. On a Mac, watch Memory Pressure and swap in Activity Monitor.
Soldered memory changes the math. When I bought a Mac mini M6 in late September, the 32GB upgrade cost ₩680,000, while one DDR5 32GB stick for my Windows PC was around ₩750,000. Even at 32GB, I ran short about four times in my first month on that Mac.
Some buyers start with a single 16GB stick at ₩350,000–400,000 and accept single-channel bandwidth until a matching second stick arrives. DDR4 only makes sense if you already own an AM4 or other DDR4 platform; for a new build, current platforms take DDR5 only.
In a sample of about 40 relevant Naver posts, 9 asked exactly this wait-or-buy question, and 2 came from people who stockpiled RAM and now regret it.
Black Friday and used sticks
I’m not waiting for Black Friday. From ₩788,020 on November 7, a 32GB stick would need to fall more than 36% to reach ₩500,000. Retail RAM is following contract prices right now, not sale dates, so a discount is a small bonus at best.
Used prices move faster than new ones. A Korean price post on October 20, 2026 put used DDR4 16GB at ₩102,136, down 17.1% in a week, and a Joonggonara listing offered DDR5-4800 16GB for ₩250,000. Dealsite (Korean) reported the same day that Q3 smartphone and PC shipments fell more than 20%, with more used-parts trading.
I still don’t buy used RAM. A bad stick looks like a good one, and a mismatched pair can cause dual-channel trouble.
If the same build died tomorrow
I’d open .wslconfig before Danawa again. The fix took an hour and no money, and the ₩1.5 million upgrade would only have covered for a default setting.
So I’m waiting, but with a trigger: six to nine months with no purchase. I’ll revisit when one 32GB stick drops below ₩500,000, or when I need seven or eight containers running alongside a build.
When I do buy, I’ll start from Danawa’s lowest-price list, where about 240 sellers carried that 32GB stick on October 29. I’ll compare two or three officially distributed sellers on the real total: rating, shipping and card discount. At close to ₩800,000 a stick, a few percent is tens of thousands of won. The two 16GB sticks I pull out go up for sale.
Prices here are as of November 7, 2026. I’ll update this post after TrendForce’s Q1 2027 numbers.
