Short version: server memory is the tightest component market of 2026. On 15 September the fixed contract price of a 64GB DDR5 server module stood at $1,500, 5.5 times the $272 of a year earlier, with spot trades reported at $3,100 (Seoul Economic Daily, 17 September 2026). Lead times on large orders run past 40 weeks and distributor quotes are valid for 48 to 72 hours (TechTimes, 7 September 2026). Below are the prices in our own catalogue on 20 September 2026, by generation and capacity, so you can compare before you buy.
What DDR5 and DDR4 registered modules cost at Memory Clearance today
Figures are the median online price across every single registered module (RDIMM) of that capacity that was priced and in stock in our catalogue on 20 September 2026. Kits and load-reduced modules are excluded. Prices change daily with the vendor feed; the collection links show the live list.
| Module | Priced, in stock | Median price | Median per GB | Lowest price |
|---|---|---|---|---|
| DDR5 32GB RDIMM | 101 part numbers | $1,792 | $56.00 | $1,325 |
| DDR5 64GB RDIMM | 69 part numbers | $3,186 | $49.78 | $2,807 |
| DDR5 96GB RDIMM | 8 part numbers | $4,716 | $49.13 | $3,734 |
| DDR5 128GB RDIMM | 21 part numbers | $6,188 | $48.34 | $5,136 |
| DDR5 256GB RDIMM | 14 part numbers | $9,212 | $35.98 | $8,888 |
| DDR4 16GB RDIMM | 718 part numbers | $193 | $12.06 | $107 |
| DDR4 32GB RDIMM | 637 part numbers | $358 | $11.19 | $97 |
| DDR4 64GB RDIMM | 208 part numbers | $929 | $14.52 | $292 |
| DDR4 128GB RDIMM | 45 part numbers | $1,354 | $10.58 | $543 |
Two things stand out. In our catalogue DDR5 prices step down per gigabyte as capacity rises, whereas the new-module tracker reports 128GB costing more per gigabyte than 64GB. And DDR4 is where the spread between OEM-branded and bare modules is widest: for 64GB, the lowest priced RDIMM in stock is $292 against a median of $929, because Dell, HPE and Lenovo part numbers carry a premium over the same Samsung, Micron or Hynix module sold bare.
How that compares with the market
- Contract and spot, 64GB DDR5 server module: $1,500 fixed contract on 15 September 2026, $3,100 reported on the spot market; TrendForce expects third-quarter server DRAM contract prices up another 13 to 18 percent (Seoul Economic Daily, 16 and 17 September 2026).
- New retail, DDR5 ECC RDIMM: $29.56 to $39.06 per gigabyte, a 64GB module about $2,064 and a 128GB module about $5,000, as of 16 September 2026 (Capital and Compute server memory tracker).
- DDR4: DDR4 ECC RDIMM prices rose roughly 60 to 80 percent between early 2025 and the first quarter of 2026; DDR5 ECC RDIMM prices rose 100 to 116 percent over the same period (DataCenterDisk, 17 August 2026). DataCenterDisk's server RAM market report of 23 July 2026 put new DDR4 ECC modules at a median of $8.33 per gigabyte, about $533 for a 64GB module.
- Supply: Samsung and SK Hynix held fewer than 10 days of finished DRAM inventory, according to a KB Securities report of 7 September 2026 (TechTimes, 7 September 2026). The three DRAM makers are steering wafer capacity to HBM for AI accelerators, and the shortage is expected to persist through 2027 and by some estimates into 2028 (CSIS, 17 September 2026).
Read together: our 64GB DDR5 median ($3,186) sits near the reported spot price ($3,100) and above new retail ($2,064), which is what an in-stock channel looks like in a shortage, and our cheapest 64GB DDR5 in stock ($2,807) is below spot. On DDR4 the picture is two-sided: our 64GB DDR4 median ($929) is above the tracker's new-module median (about $533 for 64GB), while our lowest 64GB DDR4 in stock ($292) is well below it, because OEM-branded part numbers carry a premium over the same module sold bare and each listing is priced to its stated condition.
What to do if you are buying this quarter
- Buy the capacity you need now, not the capacity you might need. Prices are forecast to keep rising through the quarter and the makers hold almost no buffer stock.
- Prefer two 64GB modules over one 128GB where slots allow; the per-gigabyte gap is roughly 17 percent on new stock, and some cloud and OEM configurations have begun shifting that way (TrendForce, cited by Capital and Compute).
- Consider DDR4 for platforms still on it. A 64GB DDR4 RDIMM from $292 keeps a third-generation Xeon Scalable or EPYC Milan fleet running without competing for DDR5 allocation.
- Get a written quote and ask for its price-valid date. Request a volume quote for anything above a handful of modules, listing the part numbers and counts.
