• About Testing Levels
• Use SIMMS with Similar Metal Contacts Only

System Memory Combinations
The Advanced/RH motherboard provides six 72-pin SIMM sites for memory expansion. The sockets support 512 KB x 32 (2MB double sided SIMMs only), 1M x 32 (4 MB), 2M x 32 (8 MB), 4M x 32 (16 MB), and 8M x 32 (32 MB) single-sided or double-sided SIMM modules. Minimum memory size is 8 MB and maximum memory size, using six 32 MB SIMM modules, is 192 MB. Memory timing requires 70 ns fast page devices or, for optimum performance, 60 ns EDO DRAM. 36-bit SIMM modules may be used for parity or ECC generation and checking.

The six sockets are arranged as Bank 0, Bank 1, and Bank 2. Each bank consists of two sockets and provides a 64/72-bit wide data path. Both SIMMs in a bank must be of the same memory size and type, although each bank may have different types of memory installed. It is even possible to have 70 ns Fast Page DRAM in one bank and 60 ns EDO DRAM in the other, in which case each bank is independently optimized for maximum performance. Any combination of the banks may be populated. There are no jumper settings required for the memory size or type, which is automatically detected by the system BIOS. The Advanced/RH motherboard supports only tin-lead SIMMs.

• EDO DRAM
  Extended Data Out, or Hyper Page, DRAM is designed to improve the DRAM read performance. EDO DRAM holds the memory data valid until the next CAS# falling edge, unlike standard fast page mode DRAM which tri-states the memory data when CAS# negates to precharge for the next cycle. With EDO, the CAS# precharge overlaps the data valid time, allowing CAS# to negate earlier while still satisfying the memory data valid window time.

• Supported Memory SIMM Sizes and Configuration
  8 MB is the minimum memory size supported by the Advanced/RH motherboard. 512 MB is the maximum memory that can be supported in any combination of SIMMs from the table.

  Supported SIMM Sizes   	Bank Size	Note
  512K x 32 (2 MB)	4MB           	1
  1M x 32 (4 MB) 		8MB            	
  2M x 32 (8 MB) 		16MB         	
  4M x 32 (16 MB)  	32MB           	
  8M x 32 (32 MB) 	64MB           	2
  
  Note 1: 512K x 32 SIMMs are supported, however, they must be double-sided SIMMs
  Note 2: When using single-sided high density SIMMs such as 32 MB single-sided, 
  	SIMMs that have less than 32 MB per side will NOT be recognized in the system.
  

Tested SIMM Vendors - Fast Page SIMMs
The following tables list SIMMs that have been tested. SIMMs that are not listed should also function properly as long as their specifications are compatible with the devices listed below. In general, SIMM devices that are faster than those specified for a given platform will work, although no extra performance will be realized.

All Sizes: Tin-lead contacts.

In general, SIMM devices that are faster than those specified for a given platform will work, although no extra performance will be realized.

Note: 60ns EDO SIMMs are required when the external CPU clock is set to 66 MHz (e.g., for the 100, 133, 166 and 200 MHz Pentium processor). Either 60ns or 70ns SIMMs can be used for external clock frequencies of 50 MHz and 60 MHz, but no additional performance will be seen with the 60ns SIMMs.
