F Memory The dc5750 series computers with AMD-based processors come with double data rate 2 synchronous dynamic random access memory (DDR2-SDRAM) dual inline memory modules (DIMMs). Ä CAUTION: DDR and DDR2 memory modules are not interchangeable. DDR2-SDRAM DIMMs The memory sockets on the system board can be populated with up to four industry-standard DIMMs. These memory module sockets are populated with at least one preinstalled memory module. To achieve the maximum memory support, you can populate the system board with up to 8GB of memory configured in a high-performing dual channel mode. For proper system operation, the DDR2-SDRAM DIMMs must be: ■ industry-standard 240-pin ■ unbuffered PC2-4300 533 MHz-compliant, PC2-5300 667 MHz-compliant, or PC2-6400 800 MHz-compliant ■ 1.8volt DDR2-SDRAM DIMMs The DDR2-SDRAM DIMMs must also: ■ support CAS latency 4 (DDR2/533 MHz and DDR2/667 MHz) and CAS latency 5 (DDR2/667 MHz and DDR2/800 MHz) ■ contain the mandatory JEDEC SPD information In addition, the computer supports: ■ 256Mbit, 512Mbit, AND 1 Gbit non-ECC memory technologies ■ single-sided and double-sided DIMMS ■ DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not supported ✎ The system will not start if you install unsupported DIMMs. DIMM Sockets There are four DIMM sockets on the system board, with two sockets per channel. The sockets are labeled XMM1, XMM2, XMM3, and XMM4. Sockets XMM1 and XMM2 operate in memory channel A. Sockets XMM3 and XMM4 operate in memory channel B. Service Reference Guide, dc5750 437963-001 F-1
