Key takeaways
- Between 22 September and 17 October 2026 (25 days), the median price change across 1,803 matched server RDIMM part numbers in the Memory Clearance catalogue was 0.0%: 581 rose, 689 fell and 533 were unchanged.
- DDR5 256GB RDIMM: 13 of 14 matched part numbers rose between 22 September and 17 October 2026, a median change of +65.16%, and the catalogue median on 17 October 2026 was $14,294 against $9,212 in the September table.
- On 17 October 2026 the Memory Clearance catalogue median for a 128GB DDR5 RDIMM was $48.34 per GB, below the $51.36 per GB median for a 64GB DDR5 RDIMM.
- On 17 October 2026 the catalogue median for a 64GB DDR5 RDIMM was $3,287 and the lowest was $3,039, both above the $2,245.00 lowest new 64GB DDR5 module on the DataCenterDisk tracker updated 18 October 2026.
- For a 64GB DDR4 RDIMM on 17 October 2026, the median for server-maker part numbers (Dell, HPE, Lenovo and others) was $1,008 against $732 for memory-brand modules, a premium of 37.8%.
Short version: between 22 September and 17 October 2026, the typical server RDIMM in the Memory Clearance catalogue did not change price, yet individual part numbers moved a long way in both directions. The exception is 256GB, where 13 of 14 DDR5 part numbers rose. Chip contract prices are a different story: Barclays figures reported by Wccftech on 12 October 2026 show DDR4 contract prices up 24% over three months and DDR5 up 20%. Those are memory chip contract prices, not module prices.
The same part numbers, 22 September to 17 October 2026
We compared 1,803 part numbers that carried a price on both dates. The median change was 0.0%. 581 rose, 689 fell and 533 were unchanged. Individual prices still moved a lot: 670 part numbers moved by more than 10%, of which 321 went up and 349 went down.
| Module | Part numbers compared | Rose | Fell | Unchanged | Median change per part number | Median 22 Sep | Median 17 Oct |
|---|---|---|---|---|---|---|---|
| DDR4 16GB RDIMM | 705 | 218 | 253 | 234 | 0.0% | $196 | $196 |

| DDR5 96GB RDIMM | 7 | 2 | 1 | 4 | 0.0% | $4,651 | $4,651 |
| DDR5 128GB RDIMM | 21 | 9 | 1 | 11 | 0.0% | $6,188 | $6,188 |
| DDR5 256GB RDIMM | 14 | 13 | 1 | 0 | +65.16% | $8,655 | $14,294 |
The 256GB modules are the exception. All 7 DDR4 256GB part numbers rose, with a median change of 18.08%. Of the 14 DDR5 256GB part numbers, 13 rose and 1 fell, with a median change of +65.16%.
The two medians in the table measure different things. The column "median change per part number" takes each part number's own change and finds the middle one. The two median price columns take the middle price on each date. DDR4 128GB shows the gap: the median change per part number was 0.0% (14 rose, 15 fell, 16 unchanged), while the median price moved from $1,354 to $1,535, a rise of 13.3%.
The 17 October catalogue table
This table uses the same method as the September edition: the median online price across every single registered module (RDIMM) of that capacity that was priced and in stock on 17 October 2026, next to the September table. Seven of the nine medians are within 3.2% of September. DDR5 256GB is up 55.2% and DDR4 128GB is up 13.3%.
| Module | Priced, in stock | Median price | Median per GB | Lowest price | September median |
|---|---|---|---|---|---|
| DDR5 32GB RDIMM | 104 part numbers | $1,836 | $57.39 | $1,386 | $1,792 |
| DDR5 64GB RDIMM | 76 part numbers | $3,287 | $51.36 | $3,039 | $3,186 |
| DDR5 96GB RDIMM | 8 part numbers | $4,716 | $49.13 | $4,024 | $4,716 |
| DDR5 128GB RDIMM | 21 part numbers | $6,188 | $48.34 | $5,381 | $6,188 |
| DDR5 256GB RDIMM | 14 part numbers | $14,294 | $55.83 | $9,593 | $9,212 |
| DDR4 16GB RDIMM | 805 part numbers | $196 | $12.25 | $81 | $193 |
| DDR4 32GB RDIMM | 681 part numbers | $358 | $11.20 | $141 | $358 |
| DDR4 64GB RDIMM | 233 part numbers | $939 | $14.66 | $292 | $929 |
| DDR4 128GB RDIMM | 50 part numbers | $1,535 | $11.99 | $933 | $1,354 |
A catalogue median depends on which listings are priced and in stock on the day. The count changed between editions: DDR4 16GB went from 718 to 805 priced part numbers, and DDR5 64GB from 69 to 76. That is why the index above compares the same part numbers on both dates. DDR4 256GB has no catalogue row: the September table had none and it has no collection page.
One per-gigabyte fact about this catalogue on this date: a 128GB DDR5 RDIMM has a median of $48.34 per GB, which is cheaper per gigabyte than a 64GB DDR5 RDIMM at $51.36 per GB. This is a statement about catalogue prices on 17 October 2026 and is not compatibility advice.
Server-maker part numbers against memory-brand modules
We split the same 17 October catalogue into server-maker part numbers (Dell, HPE, HP, Lenovo, Supermicro, IBM, Fujitsu) and memory-brand modules (Samsung, SK hynix, Micron, Kingston). At 16 to 64GB, the server-maker median is higher in every row. At DDR4 128GB the premium reverses: the server-maker median is $1,415 against $1,965 for memory-brand modules.
| Module | Server-maker part numbers | Server-maker median | Memory-brand modules | Memory-brand median | Server-maker premium |
|---|---|---|---|---|---|
| DDR4 16GB RDIMM | 244 | $220 | 561 | $193 | +13.8% |
| DDR4 32GB RDIMM | 242 | $414 | 439 | $347 | +19.4% |
| DDR4 64GB RDIMM | 91 | $1,008 | 142 | $732 | +37.8% |
| DDR4 128GB RDIMM | 16 | $1,415 | 34 | $1,965 | -28.0% |
| DDR5 32GB RDIMM | 18 | $2,087 | 86 | $1,721 | +21.3% |
| DDR5 64GB RDIMM | 15 | $3,734 | 61 | $3,186 | +17.2% |
| DDR5 128GB RDIMM | 8 | $7,677 | 13 | $5,381 | +42.7% |
The premium is +37.8% for DDR4 64GB and +17.2% for DDR5 64GB. DDR5 128GB shows +42.7% on 8 server-maker part numbers.
How that compares with the market
- Chip contract prices (not module prices): Barclays figures reported by Wccftech, 12 October 2026: DDR4 contract prices jumped by 4% monthly and 24% on a three month basis in October, and DDR5 prices jumped by 3% and 20% during the same period.
- Forecast: TrendForce, 30 September 2026, projects conventional DRAM contract prices to grow 10 to 15% quarter on quarter in 4Q26 and says server DRAM is expected to remain undersupplied in 4Q26. TrendForce gives no separate server DRAM percentage and no DDR4 against DDR5 split.
- New 64GB DDR5 module: DataCenterDisk, updated 18 October 2026, lists the lowest in-stock module as a Samsung at $2,245.00, or $35.08 per GB, and three in-stock new modules from $2,245.00 to $3,109.55. Our 64GB DDR5 median on 17 October 2026 is $3,287 and our lowest is $3,039 (a refurbished Samsung), so both sit above that tracker's lowest new module. Our 64GB DDR5 catalogue holds 64 refurbished and 12 new part numbers.
- 256GB DDR5: DataCenterDisk, updated 18 October 2026, shows one in-stock module, a V-Color at $7,519.99, or $29.37 per GB, sold on Amazon. Our 256GB DDR5 median is $14,294 and our lowest is $9,593 (a new HPE part number).
Read plainly: on 64GB DDR5 the tracker's lowest new module is cheaper than any 64GB DDR5 module priced online in our catalogue on these dates, and the one in-stock 256GB DDR5 module on that tracker is below our lowest 256GB listing. The comparison is of one tracker's lowest in-stock module against our median and lowest, on dates one day apart.
What to do if you are buying this quarter
- Check the price on the day and ask for a dated volume quote. Prices in this report are for 17 October 2026. Request a volume quote for anything above a handful of modules, with part numbers and counts.
- Look at per-gigabyte prices at 128GB. In this catalogue on 17 October 2026, a 128GB DDR5 RDIMM has a median of $48.34 per GB against $51.36 for 64GB.
- Compare the server-maker part number with the memory-brand module of the same specification. At DDR4 64GB the server-maker median is $1,008 against $732.
- For 256GB, compare before buying. 13 of 14 DDR5 256GB part numbers rose between 22 September and 17 October 2026, and the DataCenterDisk tracker, updated 18 October 2026, shows a lower price, $7,519.99, for its one in-stock module.
Browse by specification: DDR5 server memory, DDR5-4800, DDR5-5600, DDR4-3200, DDR4 RDIMM and LRDIMM, or the full collections index. Last month: Server memory prices, September 2026.
Method: the catalogue table uses the same query as the September edition: single registered ECC modules (RDIMM) in the Server Memory category whose name states DDR4 or DDR5 and a capacity, with load-reduced modules (LRDIMM) and kits excluded, counted only when the price is shown online, above zero and the listing is marked in stock; the figure is the median of the online price. The index compares every in-scope part number that shows a price online and is marked in stock today and carried a price above zero in both the 22 September 2026 and the 17 October 2026 vendor price export (the first and latest daily exports since the vendor feed took over pricing; 21 daily exports in that window). A change within half a percent counts as unchanged. Catalogue prices come from the vendor price export applied daily at about 13:10 UTC. The latest applied export is dated 17 October 2026; the catalogue query ran on 18 October 2026 before that day's export was applied, so it reflects 17 October prices. DDR5 16GB is excluded: one in-stock listing is a DDR4 part number titled DDR5, so that group is unreliable until fixed. Market figures are quoted from the sources named, with their dates.
