Lenovo ThinkSystem SR650 V3
The DDR5 generation of Lenovo's 2U: LGA4677, 32 DDR5 DIMM slots, PCIe Gen5 and XClarity management. It is the platform that appears in our enquiries when a buyer wants a current-generation 2U without paying new-channel prices - and the memory is the reason it costs what it costs.

SR650 V3 is LGA4677 with DDR5-4800/5600 in 32 slots - a different memory generation from the SR650 V2 (LGA4189, DDR4-3200). DDR5 RDIMM pricing is the dominant cost line in a V3 build, so confirm the memory configuration before comparing quotes across platforms. Platform figures are the vendor-published specification for this model; confirm the exact configuration against the service tag before a large purchase. Memory for this generation: server memory range. Relative buying rules: memory upgrade guides. Range: Lenovo ThinkSystem.
Transparent Pricing
2026 Reference Pricing by Configuration
Pricing for SR650 V3 depends on configuration - CPU model and count, memory population, drives, risers and PSU. We quote the exact configuration against confirmed stock, with the date the figure holds until stated in writing.
Single unit
On Request
Configured to your bill of materials; condition and test record stated line by line.
Multi-unit build
On Request
3-20 units matched for configuration, with staging and export documentation prepared per destination.
No price figure is published on this page by design. Quotations state the configuration, condition and the date the figure holds until. Related comparison pages: all comparisons.

Quality Process
What We Check Before a SR650 V3 Ships
Service Tag and Configuration
Service tag checked against the as-built configuration: CPU model and count, DIMM population, risers, drive bays and PSU rating are all documented before dispatch.
Memory Population Test
All 32 DIMM slots are addressed, with the population verified channel by channel - a partially populated platform is reported as such rather than described as "full".
CPU, Thermal and Fan Check
Sustained load with per-core clocks, package temperatures and fan behaviour logged; throttling units or units with failing fans are rejected.
Drive, RAID and Firmware
Drive bays and RAID controller tested per the configuration, and firmware checked against the vendor's current supported release.
Condition and Cosmetic Grading
Condition (new, pull or refurbished) stated line by line, with rail kit, bezel and cable completeness recorded in the acceptance note.
Report in the Box
Every unit ships with its per-machine diagnostic report and warranty. Full process: inspection guide.
Frequently Asked Questions
What CPUs does the SR650 V3 take?
The SR650 V3 is the 4th/5th Gen Intel Xeon Scalable (Sapphire/Emerald Rapids) platform on LGA4677, dual socket. Dual-socket boards of this generation need matched CPU pairs (same model and stepping) to train memory correctly. Confirm the exact CPU SKU against the service tag before ordering parts.
How much memory can the SR650 V3 take?
The platform has 32 DDR5-4800/5600 DIMM slots. Up to 8TB (vendor-rated, configuration dependent) is the vendor-rated ceiling with the largest supported modules; the practical ceiling for a given build is slots x module size, and the speed can step down at full population. Send the population you are aiming for and we check the rank limit before quoting.
How does the SR650 V3 compare with its successor?
SR650 V3 is the DDR5 platform: LGA4677, 4th/5th Gen Xeon Scalable, 32 DDR5 slots and PCIe Gen5. SR650 V2 is LGA4189 with DDR4-3200 and PCIe Gen4. They are different generations with different memory - do not compare a V2 quote with a V3 bill of materials.
What condition are the SR650 V3 units in?
New, pull and refurbished units are all available, and the condition is stated line by line before you commit. Each unit ships with its per-serial test record and a 1-year written warranty; rails, bezel and cable completeness are recorded in the acceptance note.
How do you ship a SR650 V3, and can you match several units?
From the Hong Kong warehouse with full export documentation, typically 3-7 days by air, on a pallet for multi-unit orders. For 3+ units we stage them together, verify a consistent configuration (CPU, memory, firmware, drives) and ship as one documented batch so the rack comes up as a matched set.
Request a SR650 V3 Quote
Send the bill of materials: CPU model and count, memory population, drives, risers, PSU and destination. We confirm what can be built or sourced, then quote against confirmed stock with the date the figure holds until.
