The Corsair New Factory Tour in Fremont, CA, USA was a September 30, 2005 Hardware Secrets report about a larger Fremont assembly plant—not a DRAM fabrication facility. Corsair assembled memory modules, screened and tested chips, programmed SPDs, added heatsinks and labels, then packed and shipped finished products. The site had six production lines, up from five.
Key takeaways
- Hardware Secrets published the new Corsair Fremont factory report on September 30, 2005; the page later displayed a February 24, 2023 update date.
- The newer building had six production lines compared with five at the earlier Fremont facility, plus additional testing, inventory, packing, and shipping capacity.
- Corsair assembled memory modules from PCBs, supplier-made DRAM chips, supporting components, and SPD devices; the Fremont site did not fabricate DRAM wafers or chips.
- The documented production sequence ran from solder-paste application and pick-and-place placement through reflow, inspection, depanelization, testing, labeling, packing, and shipping.
- A new chip-testing and sorting machine helped select chips for high-performance memory, but chip sorting was not the same as manufacturing better silicon or guaranteeing an overclock.
What did the Corsair New Factory Tour in Fremont, CA, USA document?
The Corsair New Factory Tour in Fremont, CA, USA documented a larger Fremont building that Corsair had moved into by September 2005. The report was a follow-up to an earlier Hardware Secrets visit to Corsair’s previous Fremont facility in July 2005, so “new” described the newer plant relative to that period—not a current expansion or a modern factory opening. The original report is available in Hardware Secrets’ September 30, 2005 factory-tour article.
The most important historical distinction is between memory-module manufacturing and semiconductor fabrication. Corsair’s Fremont operation assembled and tested memory modules. The available tour reports do not say that Corsair manufactured DRAM chips from silicon wafers. Semiconductor suppliers produced the chips, while Corsair combined those chips with memory circuit boards and other components, screened them, tested the completed modules, and sold them under Corsair’s product lines.
How did the new Fremont facility differ from the previous factory?
The newer Fremont facility increased both production capacity and the physical space available for testing and fulfillment. Hardware Secrets reported six production lines at the new site, compared with five at the earlier facility. The newer building also added a memory-chip testing and sorting machine, more module-testing stations, and expanded areas for inventory, packing, and shipping.

| Facility feature | Earlier Fremont site | Newer Fremont site in 2005 |
|---|---|---|
| Production lines | Five | Six |
| Chip testing and sorting | The earlier report does not document the newer machine | A new memory-chip testing and sorting machine was reported |
| Module testing | Existing testing capability | More module-testing stations |
| Inventory and fulfillment | Less space than the new building | More room for inventory, packing, and shipping |
| Historical role | Fremont assembly and testing operation | Expanded Fremont assembly and testing operation |
The expansion mattered because memory production is not only a board-assembly problem. A manufacturer also needs room to hold incoming chips and PCBs, route products through testing, package finished modules, and prepare orders for shipment. The 2005 report presents the move as a capacity and logistics upgrade rather than as the creation of a semiconductor fab.
Did Corsair manufacture the DRAM chips?
No. The 2005 Fremont operation described by Hardware Secrets assembled memory modules, while semiconductor manufacturers supplied the DRAM chips. The earlier Fremont report named Samsung and Micron among chip sources, and the newer tour reported seeing Infineon and Nanya chips at the facility. Those names are historical examples from the two 2005 reports, not a complete or current Corsair supplier list.
A DRAM manufacturer fabricates semiconductor dies on wafers and packages them into chips. Corsair’s documented Fremont work began later in the chain: with memory PCBs, DRAM chips, supporting components, SPD devices, and, for some products, heatsinks. Corsair then assembled, screened, tested, labeled, packaged, and shipped the modules.
This distinction prevents a common historical error. Saying that Corsair “made memory” is reasonable when referring to finished memory modules, but saying that Corsair fabricated the DRAM silicon would overstate what the Fremont factory tour described.
How were Corsair memory modules assembled in Fremont?
The 2005 tour described a conventional surface-mount assembly flow followed by programming, testing, finishing, and fulfillment. The sequence was broadly as follows:

- Solder-paste application: Solder paste was applied to the appropriate contact areas of a memory PCB panel.
- Surface-mount placement: Pick-and-place equipment positioned chips and other surface-mount components on the PCB.
- Reflow soldering: The populated panel passed through a reflow oven, where heat melted the solder paste and attached the components to the board.
- Visual inspection: Operators or inspection equipment checked component placement and solder joints for visible problems.
- Depanelization: The larger PCB panel was separated into individual memory modules.
- SPD programming and quick manual testing: The module’s SPD device was programmed, followed by an early manual check.
- Memory-module testing: The completed module was tested as a memory component.
- Functional testing: The module went through a further operational check in a test setup or system.
- Heatsink installation: A heatsink was installed when the product design required one. Heatsinks were optional, so this was not necessarily a step for every module.
- Labeling: Product labels were applied after the required assembly and testing stages.
- Packing: Finished modules were placed into their product packaging.
- Shipping: Packed products moved into the facility’s shipping process.
The newer tour said panels held five or six modules. The earlier report described six-module panels, but the two accounts should not be turned into a universal rule. Panel size can vary with the board design, panel layout, product configuration, or line setup.
Historical Fremont production flow: supplier DRAM chips and PCBs → solder paste → pick-and-place → reflow oven → visual inspection → depanelization → SPD programming → manual check → module testing → functional testing → optional heatsink → labeling → packing → shipping.
What was the chip-testing and sorting machine used for?
The new chip-testing and sorting machine evaluated individual memory chips and helped identify chips suitable for high-performance modules. The machine was particularly relevant to Corsair’s performance-memory business because chips with stronger test results could be selected for products intended to operate at speeds above standard specifications.
Chip sorting is sometimes described casually as “making better memory,” but that wording is misleading. The sorter did not manufacture new silicon, alter the physical design of a DRAM chip, or automatically overclock a module. The machine measured and classified available chips so Corsair could use chips with suitable characteristics in products aimed at higher performance.
Chip selection also did not guarantee a particular overclock in every computer. Final results can depend on the complete module design, memory settings, motherboard, processor memory controller, cooling, firmware, and the individual system. The historical report supports the narrower claim that the equipment helped sort chips for high-performance modules that might operate above standard speeds.
What did SPD programming do?
SPD means Serial Presence Detect. An SPD device on a memory module stores configuration information that a computer can read, including module parameters such as supported timings. During the documented Fremont process, Corsair programmed the SPD device before carrying out the later module and functional tests.

SPD programming is separate from manufacturing the main DRAM chips. It is also not the same claim as support for modern enthusiast memory standards. The 2005 source documents SPD programming and timing information, but it does not establish which later standards, firmware features, or performance profiles current Corsair memory uses. Modern XMP and EXPO terminology should not be projected backward onto this factory report without additional evidence.
What kinds of testing took place?
The tour described several checkpoints rather than one single test. Each checkpoint addressed a different possible failure:
| Test or checkpoint | What it addressed | What the historical source does not establish |
|---|---|---|
| Visual inspection | Visible placement errors, soldering problems, or board defects | Specific inspection technology, defect thresholds, or failure rates |
| Quick manual testing | An early check after SPD programming | Exact test duration, software, or acceptance criteria |
| Memory-module testing | Whether the completed module behaved as a memory component | Detailed electrical limits or test patterns |
| Functional testing | Whether the module operated in a functional test setup | Specific test platform, temperature, or error tolerance |
| Chip sorting | Whether individual DRAM chips were suitable for targeted performance grades | A guaranteed overclock or a universal performance rating |
The available reports do not provide modern-style quality-control statistics, test temperatures, error thresholds, production yields, or exact testing times. Those details should remain unknown rather than being filled in from assumptions about present-day memory manufacturing.
Why was Fremont strategically useful to Corsair?
According to the earlier July 14, 2005 Hardware Secrets factory report, the U.S. Fremont operation gave Corsair a faster response option for certain products and orders. The report said a large server-memory order could potentially be produced and delivered in two or three days. That was a historical example of the facility’s intended responsiveness, not a current Corsair delivery guarantee.
The earlier report also described a division of work between facilities. Fremont produced high-end XMS memory and server modules at that time, while a Taiwan factory produced entry-level Value-series modules. The description applies to the July 2005 account and should not be treated as a complete map of Corsair’s current supply chain.

| Historical location or operation | Role reported in 2005 | How to interpret it |
|---|---|---|
| Fremont, California | High-end XMS and server-module assembly and testing | A historical account of the U.S. operation |
| Taiwan facility | Entry-level Value-series module production | A historical account from the earlier report |
| Semiconductor suppliers | DRAM-chip manufacturing and supply | Separate from Corsair’s module assembly work |
The Fremont model therefore combined local assembly and testing with supplier-made chips. That arrangement could help Corsair react quickly to specialized or server-memory demand without requiring Corsair to own the wafer-fabrication process.
What should not be inferred about Corsair manufacturing today?
The Fremont tour is historical documentation from 2005. The fact that the Hardware Secrets page displays a February 24, 2023 update date does not turn its 2005 manufacturing observations into current operational facts.
- The available material does not establish that the 2005 Fremont plant still operates.
- The available material does not establish that Corsair currently offers public factory tours in Fremont.
- The 2005 supplier names—Infineon, Nanya, Samsung, and Micron—should not be presented as Corsair’s current supplier list.
- The six-line layout should not be presented as the process used by current Corsair factories.
- The 2005 XMS, server, and Value-series facility split should not be used to describe today’s product distribution.
- The historical process should not be assumed to describe current DDR5 or other modern Corsair memory products.
Corsair’s current official website shows modern product categories including memory, cases, gaming PCs, power supplies, coolers, and peripherals. The current site does not, in the reviewed material, advertise a Fremont factory tour or establish that the 2005 facility remains in operation. Current product categories are useful context, but they are not evidence of a present-day Fremont manufacturing process.
Then and now: what can a current buyer take from the tour?
The historical tour is useful for understanding how a performance-memory company added value beyond simply reselling DRAM chips. Corsair selected components, designed or specified modules, assembled PCBs, programmed SPD information, tested finished products, and created product grades. The report does not provide the modern pricing, compatibility testing, benchmarks, warranty comparison, or current availability needed to recommend a specific memory kit.
Readers moving from the historical factory story to a current build can consult Corsair’s present product and support information, but a modern purchase should be based on the system’s motherboard, processor, capacity needs, memory generation, supported speeds, and current compatibility documentation—not on assumptions about the 2005 Fremont plant.

Why the 2005 Fremont tour still matters
The key story is not that Corsair fabricated DRAM. The key story is that Corsair operated a U.S.-based memory-module assembly and testing facility that expanded from five to six production lines, added chip-screening capability, and increased space for testing and fulfillment.
The tour also shows why performance memory is more than a collection of chips on a circuit board. The production line combined automated surface-mount assembly, reflow soldering, inspection, depanelization, SPD programming, chip and module testing, optional heatsink installation, labeling, and logistics. In 2005, that combination helped Corsair target high-performance and server-memory products while relying on semiconductor suppliers for the DRAM itself.
Frequently Asked Questions
When was the Corsair Fremont factory tour published?
Hardware Secrets published the newer Corsair Fremont factory-tour report on September 30, 2005. The page later displayed a February 24, 2023 update date, but the manufacturing visit itself describes the 2005 operation.
Did Corsair make its own DRAM chips in Fremont?
No. The Fremont facility assembled and tested memory modules from supplier-made DRAM chips and PCBs; the available reports do not describe Corsair fabricating DRAM wafers or chips.
How many production lines did the newer Corsair Fremont factory have?
The newer Fremont facility had six production lines, compared with five at the earlier facility, according to the September 2005 Hardware Secrets tour report.
Did the Corsair chip sorter guarantee overclocking performance?
No. The chip-testing and sorting machine helped identify chips suitable for high-performance modules, but sorting did not guarantee a particular overclock in every computer.
The Bottom Line
The Corsair Fremont factory tour was a 2005 account of expanded memory-module assembly and testing, not a report about DRAM-chip fabrication. The newer site had six production lines, a new chip sorter, more testing capacity, and more fulfillment space. Its historical importance lies in how Corsair screened supplier-made chips and turned them into tested, labeled memory products.
