Memory Repair

Repair timelines vary depending on the issue and parts availability. Simple repairs may take about a week, while complex cases requiring special parts can take up to 4 weeks. We'll communicate the estimated timeline clearly in your quote.

We repair DDR4 and DDR5 RAM of all types — server-grade RDIMM/LRDIMM (ECC) memory, desktop UDIMM RAM, and laptop SODIMM (ECC and non-ECC). Contact us with your part number if you're unsure.

If the damage is visible — a missing component, worn gold fingers, dents or scratches — photos alone often tell us a lot. But symptoms with no external signs, like a module that looks fine yet isn't detected, can only be understood through a full diagnosis. Send photos along with a description of the symptom and we'll outline the diagnostic approach and likely cost range first.

If you commissioned a full diagnosis and the repair fails against the quote we gave you, our diagnosis was wrong — so we return your module with no charge for labor or parts. The diagnostic fee covers finding the cause and working out the fix, so it still applies; it's what makes that guarantee possible — a kind of insurance. If you specified the repair area yourself, there is no diagnostic fee, but labor is billed regardless of the outcome. Note that traces of the diagnostic and repair attempt may remain, and if you approved donor use, that module is returned with the recovered components removed. If you prefer, we can also offer to purchase the module for parts.

Yes! We accept and return shipments worldwide. We recommend DHL, FedEx, or EMS; round-trip shipping is paid by the customer and quoted per destination. See our Shipping section for packaging and customs guidelines.

All repairs come with a 90-day warranty. If the same issue recurs within the warranty period, we will repair it again at no charge. The warranty covers the specific repair performed, not pre-existing or unrelated issues.

It depends on the type of damage. Chip-level faults and visible external damage tend to repair well, but when a trace in the PCB's inner layers is broken, repair can be impractical or meaningless. Even with the cause found, part prices or job complexity can make a repair not worth recommending. Either way, we tell you exactly where things stand after diagnosis — and you decide whether to proceed.

Yes. For repair requests of 5+ modules, volume discounts are available. For datacenters and IT providers, we offer custom quotes based on your volume and schedule. Please use the quote request form above to get in touch.

Not exactly. Rework can leave flux residue or slight discoloration, and label stickers cannot always be re-applied perfectly. Every module is cleaned and fully tested before it ships back — see our repair terms for the full details.

Total cost = diagnostic fee + labor + parts (when needed); Korean customers add 10% VAT. For example, a $12 diagnostic fee plus $35 labor comes to $47. Parts depend on what's replaced — DRAM chips run about ₩30,000 (DDR4) to ₩50,000 (DDR5), and server-grade (RDIMM·LRDIMM) parts can cost more. If you specify the repair area yourself, only labor is billed — no diagnostic fee. No work proceeds until you approve the quote, and payment is due after the repair is complete and the result is confirmed.

Yes — there is no minimum quantity. We accept single-module repairs, and orders of 5 or more modules automatically qualify for a volume discount.

Inbound shipping to us is paid by the customer. We cover return shipping when the diagnostic fee plus repair labor (parts excluded) totals ₩100,000 or more; below that, return shipping is on the customer (international returns are quoted per destination). There is no upfront payment — you pay by bank transfer, or PayPal for international customers, after the repair is complete and the result is confirmed.
