Compaq EP Series manual System Memory, 4.15.1 440BX, Intel 810/810e

4.15System Memory

4.15.1440BX

The 440BX comes with at least 16 megabytes of synchronous dynamic random access memory (SDRAM) dual inline memory modules (DIMMs), upgradeable to 256 or 384 MB. The memory sockets on the system board can be populated with 16-, 32-, 64-, or

128-MB DIMMs. Self-refresh DIMMs are required on models with three DIMM sockets.

For proper system operation, the DIMMs must be industry standard 168-pin, 66-MHz or faster unbuffered SDRAM DIMMs. If your system processor has a bus speed of 66 MHz, Compaq recommends that any additional DIMMs also be 66 MHz. If the system bus speed is 100 MHz, the use of 100-MHz DIMMs is required. (Run Compaq Computer Setup to determine your system bus speed; see the Software Reference Guide for instructions.)

The SDRAM DIMMs must support CAS Latency 2 or 3 (CL = 2 or CL = 3). They must also contain the mandatory Joint Electronic Device Engineering Council (JEDEC) Serial Presence Detect (SPD) information.

DIMMs constructed with x4 SDRAM are not supported; the system will not start using unsupported DIMMs.

4.15.2Intel 810/810e

The Intel 810 comes with at least 32 MB of SDRAM DIMMs and the Intel 810e comes with at least 64-MB of SDRAM DIMMs, upgradeable to 512 MB.

The memory sockets on the system board can be populated with industry-standard DIMMs. These memory module slots are populated by at least one preinstalled memory module. To achieve the maximum memory support, you may be required to replace the preinstalled DIMM with a higher capacity DIMM.

For proper system operation, the DIMMs must be industry standard 168-pin, 100 MHz, unbuffered, PC100-compliant SDRAM DIMMs, depending on the model. The SDRAM DIMMs must support CAS Latency 2 or 3 (CL = 2 or CL = 3). They must also contain the mandatory Joint Electronic Device Engineering Council (JEDEC) Serial Presence Detect (SPD) information. DIMMs constructed with x4 SDRAM are not supported; the system will not start using unsupported DIMMs.

✎The Intel 810 does not support 66-MHz memory.

CAUTION: The DIMM sockets have gold metal contacts. When upgrading memory, it Is important to use DIMMs with gold metal contacts (not tin-lead) to prevent corrosion and/or oxidation resulting from having incompatible metals in contact with each other.

CAUTION: Static electricity can damage the electronic components of the computer or optional boards. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object.

CAUTION: When handling a memory module, be careful not to touch any of the contacts. Doing so can damage the module.
