Refurbished Memory Components FAQ

Short answers to what buyers ask most. For anything not covered, contact us or request a quote.

How does AURCAL supply memory parts?

We source to order. We do not show stock that has not been verified. When you send a part number, we check what we can source first and then reply by email with what can be refurbished, tested and supplied.

What information should I send with a request?

Send the exact manufacturer part number, quantity, the condition you require and your country. If you have a bill of materials, upload it as csv, xlsx or pdf (up to 5 MB). Application and target purchase time help us respond faster.

Does AURCAL supply chips and modules?

Yes. We source refurbished memory chips and memory modules to order. For modules, send the module part number, type and quantity so that we can confirm what can be supplied.

What does refurbished mean at AURCAL?

A refurbished part is a previously used or reclaimed component that has been inspected, restored where needed and tested before resale. We name the condition on every quote and do not describe refurbished parts as new.

What is reballing and do you do it?

Reballing replaces the solder balls on a BGA package so it can be soldered to a board again. We reball parts where needed using automatic flux dispensing, ball placement and ball inspection at our Shenzhen manufacturing base.

How are parts tested?

Parts get a visual inspection, electrical testing on dedicated DDR3, DDR4 and eMMC test machines, and burn-in. The test scope for each device type and lot is confirmed in your quote.

What is burn-in?

Burn-in operates devices under electrical and temperature stress for a period so early failures show up before shipment. Failed parts are separated and not sold as good stock.

Are parts shipped with documents?

Yes, with the documents you ask for. Every lot has an identifier linked to inspection and test data, and parts are packed ESD-safe and moisture-controlled.

Do you match the exact suffix of a part number?

Yes. Suffixes and punctuation are never merged. A part with a different suffix is a different part, and we tell you plainly when we can only offer an alternative.

Can you source end-of-life or obsolete parts?

Yes, discontinued memory is a core part of our work. We locate material, then inspect, reball, test and burn in what we find. If a part cannot be supported we tell you at once.

Is the part number list in the catalog your inventory?

No. The catalog is reference data from public manufacturer part lists, not a statement of our inventory. Availability is confirmed after you request a quote.

How long does a quote take?

A person answers every request by email. Response and delivery times depend on the part and are confirmed in the written quote.

What are the minimum order quantity and price?

Prices and minimum quantities depend on the part, condition and availability. They are stated in the written quote for your exact part number and quantity.

What is your returns policy?

See the Returns and exchange page for how to report a problem, what we need from you and how a claim is handled. Terms for each order are stated in the quote.

What is the difference between DDR3 and DDR3L?

DDR3L is the low-voltage version, running from 1.35 V instead of 1.5 V. Compatibility depends on the controller and board, so match the exact part number where possible.

Can I replace DDR4 with DDR5?

No. DDR4 and DDR5 use different voltages, interfaces and pin layouts and are not interchangeable.

How do I verify a refurbished part before I buy?

Ask for the full part number and suffix, date codes, test evidence, packaging details and written return terms. See our supplier checklist for the full list.

Are you affiliated with Samsung, SK hynix or Micron?

No. Manufacturer names are used only to identify part-number families. No affiliation, endorsement or authorization is implied.

Where are your offices?

Manufacturing and operations are in Shenzhen, China. The registered office is in Hong Kong. We also list contacts for Taiwan and other regions on the Contact page.

Can I upload a bill of materials?

Yes. Upload csv, xlsx or pdf files up to 5 MB on the quote form, or type several part numbers, one per line.
