OEM-labelled memory
Keep Dell, HPE and Lenovo option or spare numbers on their own order lines. A Samsung, Micron or SK hynix manufacturing number can support identification, but does not replace the requested OEM number.
ASTER RACKIT / Server memory
More capacity. The right memory population.
Build a memory order around the installed server—not capacity alone. Compare OEM-labelled options, component-manufacturer modules and matched lots while keeping the full part number, module type and host generation together.
Server memory / product range
Choose the purchasing route that fits your project.
Build a memory order around the installed server—not capacity alone. Compare OEM-labelled options, component-manufacturer modules and matched lots while keeping the full part number, module type and host generation together.
Component-brand modules
Request a complete manufacturer MPN, capacity, memory generation, module organisation and speed grade. These are quoted as component-brand products, not relabelled OEM options.
Matched expansion lots
For repeat deployments, specify what must match across the lot: part number, revision, rank, speed or label. Share installed DIMM details before adding capacity to existing systems.
Part-number discipline
Same manufacturer does not mean the same part number.
OEM option numbers, service-spare numbers and component-manufacturer MPNs are distinct purchasing identities. Similar hardware is not an approved substitution.
OEM-labelled parts
Specify the server brand, full option or spare PN and exact target system. The manufacturer marking can be recorded alongside it; it must not replace the OEM number on your order.
Component-brand products
Specify the manufacturer MPN and required specification. These products are quoted under their own identity, with host compatibility and any proposed OEM alternative reviewed separately.
Selection guide
Compare server memory by the job they need to do.
Use this guide to prepare your requirement. Only the complete system and exact part identity can establish a suitable configuration.
| Requirement | Typical buying purpose | Confirm before ordering |
|---|---|---|
| Capacity expansion | Add memory to an existing server fleet. | Installed modules, CPU count, free slots and desired total capacity. |
| Like-for-like replacement | Replace a failed module without changing the platform plan. | Complete existing PN, module label and server generation. |
| New memory population | Prepare a consistent build for several servers. | Required capacity per CPU, module count and platform population rules. |
| Service inventory | Hold spares for a defined installed base. | Approved PN list, permitted revisions and minimum quantities per PN. |
Build the requirement
The details that prevent the wrong part arriving.
- Module type
- Identify RDIMM or LRDIMM and the DDR generation. Do not assume that ECC alone establishes compatibility.
- Population
- State the number of installed processors, occupied DIMM slots and planned additions.
- Module label
- Retain the full PN, capacity, rank or organisation, speed grade and revision where available.
- OEM requirement
- Tell us whether OEM-labelled parts are required or component-brand alternatives may be reviewed.
- Lot consistency
- Define which fields must match; the same capacity is not a complete matched-set specification.
- Test scope
- Request the agreed memory test, platform information and any available results for the offered lot.
Project use
Support the way your team buys and deploys.
Virtualisation hosts
Balance the target capacity across your host fleet and record the installed memory before planning additions.
Maintenance teams
Build a spare list around deployed part numbers and generations, with substitutions subject to approval.
Resellers & integrators
Group repeat orders by exact PN and lot requirements so modules can be allocated to the intended systems.
OEM part directory
Start with the exact number.
Examples from the parts directory, not a live stock list. Open an item for its description and applicable requirements; confirm the offered condition, host fit and availability with sales.

Product & operations gallery
A closer view of the products and preparation.
Specific product presentations and working environments are labelled separately. Ask for current photographs of the actual units offered to you.
Before dispatch
Agree the condition. Check the complete kit.
Set the inspection and packing requirements with your quotation. A scene photograph does not establish that a particular unit has passed a test.
- Identity & visible condition
- Request readable label and connector photographs of the offered units. Record the full PN, revision and any cosmetic limitations.
- Functional checks
- Agree category-appropriate checks and the available results. Drive health, memory tests and adapter checks are different inspection scopes.
- Complete accessories
- Confirm the exact carrier, bracket, cable, rail or mounting kit on the packing list. Unlisted accessories are not assumed to be included.
- Protective packing
- Specify protection suitable for the equipment. Servers need full-base support with thick pearl-cotton foam; keep loose metal parts separate from the chassis.

Buyer questions
Clear answers before you request a quote.
Can an OEM PN and a manufacturer MPN describe similar hardware?
Yes, but they remain different purchasing identities. We retain both where available and do not substitute one for the other without agreement.
Does a higher speed grade guarantee that speed in my server?
No. Confirm the supported operating speed for the complete CPU and DIMM population.
Can I request a same-PN lot?
Yes. Specify the quantity and any revision, rank, speed or label requirements. Availability is confirmed with the offer.
What if I do not know the installed module number?
Send clear photographs of the module label and the server model. Do not include management passwords or confidential customer information.
Can I send a mixed-brand parts list?
Yes. Keep each brand, complete PN, quantity, condition preference and target system on its own line. Identify whether alternatives may be considered.
Do you sell new and pre-owned parts?
You can request either condition. The offer must identify the supplied condition, inspection scope, warranty terms and included accessories for each item.
Will a request reserve stock or place an order?
No. The request is a draft for discussion. Availability, pricing and order terms are confirmed separately.
Can customers visit the warehouse and workshop?
Contact the team to arrange a visit and discuss which equipment or inspection process you would like to see. Access and demonstration details are confirmed in advance.
