Corsair Employees RAM GUY Posted August 6, 2007 Corsair Employees Share Posted August 6, 2007 With both of these systems you would need to manually configure the BIOS settings to like whats bellow, can you tell me the bios settings you have set for both CPU and memory and any performance settings that you may have set? With a 333 FSB CPU and A8N8X-E MB: CPU Freq: 166 MHz System Performance: User Define Memory Frequency: 100% Dim Voltage to 2.7 Volts Resulting Frequency: 166MHz Memory Timings: Manual/User Define SDRAM CAS Latency: 2.5T SDRAM RAS to CAS Delay (tRCD): 3T SDRAM Row Precharge (tRP): 3T SDRAM Active to Precharge Delay (tRAS): 7T Then test the modules one at a time with http://www.memtest.org.

The ram seemed to degrade over time. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted August 7, 2007 Corsair Employees Share Posted August 7, 2007 You would need to set the manually, what was the memory frequency set to on both MB's and on what test are you getting errors? Link to comment Share on other sites More sharing options...
