55H8545 IBM System Board (Motherboard) for T-115

OEM IBM System Board 55H8545 for T-115

Designed for the T-115, the IBM 55H8545 desktop motherboard is the original-specification part for repairs and refurbishment. A like-for-like board helps keep standard OS images and drivers working across a fleet. It suits break-fix repair, refurbishment programs and IT asset recovery. Replacing only the board lets you keep the existing case, storage and peripherals in service.

Why an OEM Desktop Motherboard Matters

Using the correct IBM system board avoids the fit and compatibility problems common with generic replacements. Matching the part number on your current board is the most reliable way to confirm compatibility. The chipset sets the board's available features, from storage ports to USB and expansion lanes. System information tools show the installed CPU, which helps confirm the correct board variant.

Memory, Form Factor and Expansion

Memory and expansion options follow the original system design, so reuse modules of the same type where possible. Install memory in the configuration recommended in the system documentation for best performance. Supported memory modules give the most reliable results. Dual-channel memory configurations improve bandwidth where the platform supports them.

Benefits of This Desktop Motherboard

A replacement board is a cost-effective way to return a business or home desktop to service. A board replacement is a sustainable alternative to buying new equipment. Reliable hardware keeps users productive and support costs low.

Before You Install

Move the processor, memory, cooling and expansion cards from the old board and apply fresh thermal compound. Some OEM systems store the Windows product key and serial number in firmware, so check activation after the swap. Store the board in its anti-static bag until you are ready to install it. Power on with only essential parts connected before reassembling fully. Windows may need drivers reinstalled or reactivation after a board change.
