Intel® Desktop Boards based on the Intel® 850 chipset supports up to 2.0 GB of system memory using PC600 (300 MHz) or PC800 (400 MHz) RDRAM* RIMM* memory modules.

Note: PC700 RIMM memory modules are not a supported configuration and may run at PC600 memory speeds.

Intel Desktop Boards based on the Intel® 850 chipset has two RDRAM* channels, with each channel having two RIMM* memory module connectors. Each channel must mirror the memory size & speed installed in the other channel. If two RIMM* memory modules are installed, RIMM* memory module and one continuity RIMM* module per channel. Or there maybe two RIMM* memory modules installed into each channel.

For more information, return to the main product page and select Technical Product Specification.

Note: See the picture below for the minimum memory configuration. Two 64-MB RIMM* memory modules in Bank 0 and two continuity RIMM* memory modules in Bank 1.

This example shows the Intel Desktop Board D850GB to have 128MB of system memory.

• Bank 0 must be populated first, ensuring that the RIMM* memory modules installed in RIMM1 and RIMM2 are identical in speed, size, and density. For example, the minimum system configuration would use two 64-MB RIMM memory modules of PC600 or PC800 RDRAM* memory.
• If the desired memory configuration has been achieved by populating Bank 0, then Bank 1 should be filled with two continuity RIMM* modules.
• If memory is to be installed in Bank 1, the RIMM* memory modules installed in RIMM3 and RIMM4 must be identical in size and density to each other, and match the speed of the RIMM* memory modules in Bank 0. The RIMM* memory modules do not, however, need to match those in Bank 0 in size and density.
