Resellers, managed service providers and integrators rarely buy memory for one machine. They buy for fleets of different makes and ages, and they need the same part to be reorderable next quarter. This guide sets out a simple process for sourcing memory across client systems. For the overview and ordering options, see the reseller, MSP and integrator memory page.
Step 1: Inventory the systems
Record each distinct model once: make, model, installed memory, number of memory slots, and the memory generation (DDR3, DDR4 or DDR5). Ten identical laptops are one line, not ten. This list becomes your ordering sheet.
Step 2: Identify the module family
Desktops and many workstations use UDIMM, laptops and compact PCs use SODIMM, and servers use RDIMM, LRDIMM or ECC UDIMM. ECC and non-ECC modules are not always interchangeable, and modules from different generations do not fit each other's slots. If you are unsure, the memory by specification page groups the catalog by module type and speed.
Step 3: Match each model to a listing
Use the listing for the exact model. Start from the page for your kind of work: business fleets, servers, workstations, industrial and embedded systems, NAS, telecom and edge or rugged systems, or search by manufacturer.
Step 4: Standardize and reorder
Choose one listing and one capacity per model and use it for every unit. A standard kit per model keeps client fleets consistent, simplifies quoting, and lets you reorder the identical part for spares and growth.
Step 5: Populate correctly
Install matched modules, one per memory channel, of the same speed and capacity wherever the system has more than one slot. Mixing speeds makes the memory run at the slowest module, and mixing ranks or capacities can limit what the system supports. A two-module kit arrives matched.
Step 6: Pilot, test and document
Upgrade one unit first. Confirm in the BIOS or system information that the full capacity is detected, then run a memory test before rolling out to the rest. Record the part and the result against the model on your ordering sheet.
Step 7: Refurbishing and resale
Refurbishers handle more generations than most buyers, including DDR3. Check the generation and form factor before a bulk purchase, keep ECC and non-ECC stock separate, and confirm one sample unit of each model before buying the batch. The DDR3 SODIMM and DDR4 SODIMM collections cover common laptop generations.
Step 8: Warranty and traceability
NEMIX-brand modules carry a lifetime warranty. Register the purchase to activate it, and keep the invoice with the client's asset record.
Step 9: Buying and retiring hardware
Request a quote for fleet quantities, or open a net-terms account with the credit application on the quote page; purchase orders are accepted and volume, reseller and B2B pricing is available on request. When systems retire, NEMIX RAM offers IT asset disposition, including hardware buy-back, so the memory you pull can be returned to use.
