Are your enterprise servers new and genuine?

Yes. We supply new and factory-sealed new-old-stock (NOS) servers from Dell, Lenovo, xFusion and Inspur, sourced through authorized manufacturer channels. New servers are covered by a 3-year warranty.

Can you ship GPU and storage servers to my country?

We export to 60+ countries across North America, Europe, the Middle East, Southeast Asia, Africa and Latin America, with door-to-door freight, customs documentation and insurance handled by our team.

How fast will I receive a quotation?

Most configuration lists receive a detailed quotation within one business day. For complex deployments, our engineers confirm compatibility and provide options before pricing.

Do you support system integrators and resellers?

Yes — system integrators, IT resellers, project suppliers and tender bidders are our primary customers. We offer multi-brand consolidation, neutral configuration advice and repeat-order account support.

How do I pay, and what terms are available?

We accept international bank transfer (T/T) in USD. Standard orders are confirmed against a proforma invoice, while established repeat accounts and project bidders can discuss agreed payment terms in advance.

What is the lead time for delivery to the Middle East or Southeast Asia?

In-stock configurations are normally built and tested within a few business days, followed by door-to-door air or sea freight depending on the destination. We provide a clear timeline and tracking once the order is confirmed.

How is warranty and after-sales support handled overseas?

New servers carry a 3-year warranty. Our support team coordinates with the manufacturer and arranges replacement parts and remote troubleshooting, so you receive the same level of service in any region we ship to.

Can you build a fully custom configuration to my specification?

Yes. Send your required CPU, memory, drives, accelerators, power and networking preferences — or simply describe the workload and target budget. Our engineers specify, assemble and burn-in test the complete system before shipment.

Overview

Standard: DDR5 RDIMM, 288-pin, 6400 MT/s, 1.1 V, ECC registered, 4Rank, 8Rank.

Capacity per module: 256 GB. DRAM die vendors include Samsung; the module is carried by multiple xFusion P/Ns.

Modules run at the highest common speed supported by both the CPU and the other modules installed; mixing speeds down-clocks the whole channel to the lower rate.

Part numbers (PN aliases)

These xFusion part numbers all belong to this module type. Different P/Ns reflect speed bins, rank, die source or dedicated customer codes – not a different function.

How to choose

Install identical modules in matched channels and balance DIMMs across all memory channels. The many P/Ns on this page reflect different speed bins, die vendors and dedicated customer codes rather than different function.

Frequently asked questions

What is the capacity and type?

256 GB DDR5 registered ECC RDIMM, 288-pin, 1.1 V.

Which speeds are supported?

6400 MT/s, depending on the P/N and platform.

Which DRAM vendors are used?

Samsung; function is identical across the xFusion P/Ns.

Why are there several part numbers for the same capacity?

They reflect different speed bins, ranks, die vendors and dedicated customer codes; all are the same 256 GB DDR5 RDIMM.

Can I mix sizes and speeds?

Sizes can be mixed, but modules run at the slowest common speed; matched modules give the best performance.

How should modules be populated?

Balance DIMMs across every memory channel and follow the server's population rules for maximum bandwidth.

RDIMM vs LRDIMM?

These are standard RDIMMs for mainstream workloads; choose LRDIMM only for very large, fully populated capacities.

Which FusionServer models fit?

5 models, including 2258 V7, 2258H V8, 2288 V8, 2288H V7, 5885H V7; full list below.

Is it ECC and genuine xFusion?

Yes, registered ECC and genuine (e.g. 0620Y044), supplied new/tested with a 1-year warranty.

How do I order and get a quote?

Send the P/N or server model and quantity; we confirm compatibility and quote (no public list price).

Can you supply full memory configurations?

Yes – tell us the model and target RAM and we configure, quote and, if needed, install qualified modules.
