TC020702TB TECHNOLOGY BRIEF (cont.) ... Memory The ProLiant DL590/64 server supports up to 64 GB of industry-standard 100-MHz ECC SDRAM. Two memory boards provide 32 dual inline memory module (DIMM) sockets each to accommodate a total of 64 DIMMs (see Figure 3). One memory board attaches to the top of the processor board, and one memory board attaches to the bottom. Figure 3: Each memory board in the ProLiant DL590/64 server supports up to 32 DIMMs. Advanced ECC memory technology with single-bit error correction and double-bit and nibble error detection technology is integral to the Intel 82460GX chipset. Advanced ECC memory improves data integrity of servers and significantly reduces the probability of fatal memory errors. With fewer memory errors, overall availability of the server improves. The ProLiant DL590/64 server comes standard with 1 GB (733-MHz model) or 4 GB (800-MHz model) of memory. The 733-MHz model comes with one memory board supporting 32 DIMM sockets; the 800-MHz model comes with two memory boards supporting up to 64 GB of memory using 1-GB DIMMs. The 733-MHz model may be upgraded with an additional, optional memory board. Memory is expandable, four DIMMs at a time, to a maximum total of 64 GB. Compaq strongly recommends using DIMMs supplied by Compaq because of the rigorous testing they undergo in ProLiant systems. However, the ProLiant DL590/64 supports industry-standard 168-pin PC100 CL2 ECC Registered DIMMs with some restrictions1. The use of DIMMs that do not adhere to these restrictions may result in error messages and possible loss of data. I/O Additional performance for the ProLiant DL590/64 server is provided with a powerful 64-bit I/O subsystem. The server has eight 64-bit, 66-MHz hot-plug PCI slots and three 64-bit, 33-MHz slots (Figure 4). Slots 1, 10, and 11 operate at 5 volts and run at 33 MHz only. Slots 2 through 9 operate at 3.3 volts and will run at 33 MHz or 66 MHz. Figure 4: The ProLiant DL590/64 implements 64-bit PCI technology. 1 Check with your authorized Compaq representative for more information on these restrictions and correct memory usage. 6

Memory
The ProLiant DL590/64 server supports up to 64 GB of industry-standard 100-MHz ECC
SDRAM.
Two memory boards provide 32 dual inline memory module (DIMM) sockets each to
accommodate a total of 64 DIMMs (see Figure 3).
One memory board attaches to the top of the
processor board, and one memory board attaches to the bottom.
Figure 3:
Each memory board in the ProLiant DL590/64 server supports up to 32 DIMMs.
Advanced ECC memory technology with single-bit error correction and double-bit and nibble
error detection technology is integral to the Intel 82460GX chipset.
Advanced ECC memory
improves data integrity of servers and significantly reduces the probability of fatal memory errors.
With fewer memory errors, overall availability of the server improves.
The ProLiant DL590/64 server comes standard with 1 GB (733-MHz model) or 4 GB (800-MHz
model) of memory.
The 733-MHz model comes with one memory board supporting 32 DIMM
sockets; the 800-MHz model comes with two memory boards supporting up to 64 GB of memory
using 1-GB DIMMs.
The 733-MHz model may be upgraded with an additional, optional memory
board.
Memory is expandable, four DIMMs at a time, to a maximum total of 64 GB.
Compaq strongly recommends using DIMMs supplied by Compaq because of the rigorous testing
they undergo in ProLiant systems.
However, the ProLiant DL590/64 supports industry-standard
168-pin PC100 CL2 ECC Registered DIMMs with some restrictions

.
The use of DIMMs that do
not adhere to these restrictions may result in error messages and possible loss of data.
I/O
Additional performance for the ProLiant DL590/64 server is provided with a powerful 64-bit I/O
subsystem.
The server has eight 64-bit, 66-MHz hot-plug PCI slots and three 64-bit, 33-MHz slots
(Figure 4).
Slots 1, 10, and 11 operate at 5 volts and run at 33 MHz only.
Slots 2 through 9
operate at 3.3 volts and will run at 33 MHz or 66 MHz.
