Tested Memory
Memory testing has been performed under the following category:

Advanced Tested Memory*
Intel provides the Advanced environmental test procedures, test software and necessary hardware to an independent test lab to perform Advanced testing as requested by the memory vendors.

Memory tested by Computer Memory Test Labs (CMTL)*.

Intel Internal Tested Memory
Intel's has a limited amount of memory tested for the desktop board. These part numbers may not be readily available throughout the product life cycle.

System Memory Features

Note

Remove the AGP video card before installing or upgrading memory to avoid interference with the memory retention mechanism.

Note

The Intel® Desktop Board D845PT board has been designed to support DIMMs based on 512 Mbit technology for a maximum onboard capacity of up to 2 GB, but this technology has not been validated on this board.

The Intel® Desktop Board D845PT has two DIMM sockets and supports the following memory features:

2.5 V (only) 184-pin DDR SDRAM DIMMs with gold-plated contacts
Unbuffered single-sided or double-sided DIMMs
Maximum total system memory: 2 GB; minimum total system memory: 64 MB
200/266 MHz DDR SDRAM DIMMs only
Serial Presence Detect (SPD)
Suspend to RAM
Non-ECC and ECC DIMMs

Note

To be fully compliant with all applicable DDR SDRAM memory specifications, the board should be populated with DIMMs that support the Serial Presence Detect (SPD) data structure. This allows the BIOS to read the SPD data and program the chipset to accurately configure memory settings for optimum performance. If non-SPD memory is installed, the BIOS will attempt to correctly configure the memory settings, but performance and reliability may be impacted or the DIMMs may not function under the determined frequency.

Note

For ECC functionality, all installed DIMMs must be ECC. If both ECC and non-ECC DIMMs are used, ECC will not function.

The following table lists the supported DIMM configurations.

DIMM Capacity	Number of Sides³	DDR SDRAM Density	DDR SDRAM Organization Front-side/Back-side	Number of DDR SDRAM Devices
64 MB	SS	64 Mbit	8 M x 8/empty	8
64 MB	SS	128 Mbit	8 M x 16/empty	4
96 MB	DS	64 Mbit	8 M x 8/4 M x 16	12^{1, 2}

256 MB	DS	256 Mbit	16 M x 16/16 M x 16	8 ^{1, 2}
256 MB	SS	256 Mbit	32 M x 8/empty	8
512 MB	DS	256 Mbit	32 M x 8/32 M x 8	16 ^{1, 2}

Notes

If the number of DDR SDRAM devices is greater than nine, the DIMM will be double sided.
Front side population/back side population indicated for DDR SDRAM density and DDR SDRAM organization.
In the second column, "DS" refers to double-sided memory modules (containing two rows of DDR SDRAM) and "SS" refers to single-sided memory modules (containing one row of DDR SDRAM).
