Dimms - Compaq 159715-002 - Deskpro EN - DT 6650 Model 10000 Configuration Manual

For proper system operation, the RIMMs must be industry-
standard 184-pin, PC600–, PC700–, or PC800–compliant
RAMBUS memory modules, depending on the model. They
must also contain the mandatory Joint Electronic Device
Engineering Council (JEDEC) Serial Presence Detect (SPD)
information (1.0 or later). Intel 820 chipset–based Deskpro
models have one Direct RAMBUS channel that supports a
maximum of 32 devices. The total number of devices on all
RIMMs must be less than or equal to 32. Each RIMM includes a
label that lists the number of devices contained on the RIMM.
RIMM upgrade kits are available as options from Compaq.

DIMMs

The memory sockets on the Intel 810 and 810e chipset–based
system boards can be populated with industry-standard DIMMs.
These memory module slots are populated with 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.
If you install RIMMs of varying speeds, the system will
run at the speed of the slowest installed RIMM.
