Per-module testing before shipment

SN list ties evidence to your order

Photos before any payment

Testing workflow

Six fixed steps, every lot. Failures never ship.

Visual inspectionContacts, PCB and label condition checked module by module.

Spec verificationPart number, capacity, speed grade and rank verified against the lot list.

Memory testingMemTest86 or equivalent memory testing on every module.

Server POSTServer POST / live-system validation in representative platforms.

Failures removedAny failing module is pulled from the lot — it never ships.

Pre-shipment recheckLot recounted and rechecked against the SN list before packing.

The evidence package

Documentation that ships with your order — and the photos you see before paying.

Test report

The test report accompanying your order lists part number, capacity, speed grade, per-module result, test date and method.

Serial-number list

A per-module SN list ships with every order — the same list used for DOA verification and any return.

Part-number & brand information

Exact part numbers and brands (Samsung, Micron, SK hynix) stated per line item — no unlabelled mixes.

Photos before payment

Actual-lot photos and a sample SN excerpt are provided before any payment is made.

Condition wording

We describe condition in precise terms and avoid over-promising.

Pre-owned — Previously deployed in data-center service.
Tested — Passed the workflow above before shipment.
Server-pull — Pulled from decommissioned servers, not retail returns.
No repair history or visible corrosion where confirmed — Stated per lot where inspection confirms it.

We do not describe products as "new", "refurbished" or "zero-failure".

DOA & after-sales

Dead-on-arrival claims are verified against the SN list shipped with your order, and handled under the specific quotation and order terms agreed for that transaction. See Warranty & DOA and Returns & RMA for the process.
