| Article Summary: | This article contains information regarding why my Precision Workstation T1700 won't POST, boot, or recognize memory correctly after upgrading the memory. |
Table of Contents:
| 1. | Maximum Size of Memory Supported in the T1700 |
The Precision T1700 supports up to 32 GB of memory of either ECC (Error Checking and Correction) or non-ECC DIMMs. A minimum of 2 GB of memory can be installed in the system, but it must be a single non-ECC module. The following chart provides supported memory population configurations:
The version of Windows installed on the T1700 will also affect the amount of memory the operating system can recognize. 32-bit versions of Windows will only recognize a maximum of 4 GB of memory, and there are further limitations with some 64-bit versions of Windows. Check the memory limits for the different versions of Windows
to ensure your version of Windows is able to fully utilize the memory upgrade. Back to Top
| 2. | Memory Population Rules |
The memory controller on the T1700 supports dual-channel memory bus architecture. To ensure maximum channel performance, memory modules should always be installed in pairs of matched size, speed, and technology.
If the system has only one DIMM installed, the system memory operates in single-channel mode. The system works normally in single-channel mode, but loses the benefit of increased memory throughput from the dual-channel configuration. The system board layouts below show where the memory slots and their corresponding channels are located.

| 3. | Memory Speeds Supported |
The T1700 supports DDR3 SDRAM modules with speeds of 1600MHZ. DDR3 memory provides a boost in access speed, and also allows for individual chip capacities up to 8 GB on each memory module. A motherboard which supports DDR3 can only support this memory type as it is keyed differently than previous memory modules:
