Optimum SDRAM Settings
The optimum settings for your RAM are as follows:
DRAM Clock Host CLK (for PC100 RAM)
HCLK+PCICLK (for PC133 RAM)
Enhance Chip Performance Enabled
Force 4-way interleave Enabled
Enable DRAM 4k-Page Mode Enabled
Auto Detect DIMM/PCI Clk Enabled (this is an EMC setting and does not affect performance)
Bank x/y DRAM Timing - set as fast as you can SDRAM 8/10ns and Medium are the slowest
Normal and Fast, or Turbo is the fastest (you'll have to benchmark using Sandra: on some machines Fast is faster than Turbo!)
DRAM Bank Interleave Optimum is 4-Way
If not supported, try 2-Way, else Disable
Delay DRAM Read Latch Auto
With large amounts of RAM, you may need to increase this delay value for stability
MD Driving Strength HI is recommended for stability with most SDRAM types
If HI is unstable, try LO
This setting has no impact on performance
SDRAM Cycle length Set to 2 for CAS 2 PC133 SDRAM
Set to 3 for PC100 SDRAM, most unbranded PC133 SDRAM and PC133 CAS 3 SDRAM
Fast R-W Turn Around Enabled for maximum performance
Disabled for stability
Memory Parity/ECC Check ECC SDRAM is not supported and hence this BIOS option is not functional
