The IBM 40K7535 (40K7535 - IBM Memory Card with 2.2GHz CPU for x3755 Type 8877 Server) is a Memory Boards component engineered for sustained enterprise-class workloads. This part addresses common procurement scenarios where exact-match replacement, capacity expansion, or new-build deployment is required. Technical specifications include clock speed of 2.2 GHz. Common deployment scenarios include database server upgrades (in-memory caches, SQL buffer pools), VMware ESXi / Hyper-V virtualization host memory expansion, GPU compute scratch pools, and HPC node provisioning. Pro Disk Network sources the 40K7535 through reputable distribution channels and applies a verification check against the OEM compatibility matrix before each unit is added to active inventory. Each unit ships from a US fulfillment hub (Hillsboro OR, Atlanta GA, or Phoenix AZ) with same-day dispatch on in-stock orders before 3pm ET. 90-day Pro Disk Network functional warranty included; free US ground shipping on orders over $150.
The 40K7535 is a IBM memory boards component with clock speed 2.2 GHz. Pro Disk Network sells the 40K7535 for $262.54 with same-day US shipping and a 30-day return guarantee.

Quick Answer: What servers is the 40K7535 compatible with?
The 40K7535 is a IBM memory boards module. Confirm DIMM rank, voltage, and speed against the target server's supported memory list before deployment - mixed configurations may downclock to the slowest installed module. For server-specific population diagrams, email sales@prodisknetwork.com with your server serial number.
How fast does the 40K7535 ship?
40K7535 orders placed before 3 pm ET ship the same business day from US warehouses. Delivery is next business day to most metro ZIPs via FedEx/UPS overnight; ground delivery covers remaining US in 1-4 business days.
The 40K7535 is deployed by US enterprises, MSPs, government, and education customers across multiple infrastructure scenarios. Below are the most common deployment patterns Pro Disk Network sees in real-world orders.
In-Memory Database — SAP HANA, Redis Enterprise, Apache Ignite, Aerospike — workloads that scale linearly with DRAM capacity.
Hyper-V Cluster Node — Windows Server 2019/2022 Hyper-V hosts with Storage Spaces Direct. Dynamic memory allocation makes higher-density DIMMs cost-effective.
AI / ML Training — PyTorch and TensorFlow workloads benefit from large host memory pools for dataset preprocessing and CPU-side feature engineering.
Tanzu / Kubernetes Workers — Worker node memory expansion for high-density container deployments. Plan for 8–16 GB per moderate Pod baseline.
What is the 40K7535?
The 40K7535 is a IBM server memory module with clock speed 2.2 GHz, manufactured by IBM. Pro Disk Network ships this part new and certified-refurbished from our US warehouse with same-day dispatch on orders placed before 3 PM ET, backed by a 30-day return guarantee.

Pros
RDIMM / LRDIMM clearly labelled for population-rule clarity
Cons
Server-grade DDR module — does not work in consumer desktops
Buffered (RDIMM) modules require server motherboards
Confirm voltage and channel rules before mixed-density installs
Frequently Asked Questions about 40K7535
Is the 40K7535 a genuine IBM part?
Yes. Pro Disk Network sources every 40K7535 as factory-original IBM inventory. New units arrive sealed in OEM packaging; refurbished units are pulled from decommissioned IBM servers, surface-tested, and re-warranted by Pro Disk Network for 90 days.
What servers is the 40K7535 compatible with?
The 40K7535 is a IBM memory boards module. Confirm DIMM rank, voltage, and speed against the target server's supported memory list before deployment - mixed configurations may downclock to the slowest installed module. For server-specific population diagrams, email sales@prodisknetwork.com with your server serial number.
How fast does the 40K7535 ship?
40K7535 orders placed before 3 pm ET ship the same business day from US warehouses. Delivery is next business day to most metro ZIPs via FedEx/UPS overnight; ground delivery covers remaining US in 1-4 business days.
What is the warranty on the 40K7535?
New 40K7535 units carry the full IBM manufacturer warranty (typically 1 to 5 years depending on product line). Refurbished and bulk-OEM units include a Pro Disk Network advance-replacement warranty (90 days refurbished). DOA replacement is free within 30 days of receipt.

Compatibility: Rank, Density, and Channel Population Rules
Quad-rank modules behave differently from dual-rank: most modern Xeon platforms support 1-2 DPC (DIMMs per channel) at full speed with single- and dual-rank modules but downclock with quad-rank above 1 DPC. RDIMM and LRDIMM are not interchangeable in the same channel. ECC and non-ECC cannot be mixed. Server motherboards expect server DIMMs — the 40K7535 is a server module and will not work in consumer desktop boards.
Pricing Strategy: New, Bulk, or Refurbished
If you are buying 16 or more modules at once, request a matched-lot quote: sequential manufacturing dates and serial numbers, which reduces variance in observed memory speeds across the channel. Pro Disk Network ships matched-lot orders for free on volumes of 16+.
