Bad Sticks of VS DDR

[alexhanlei]

I have a pair of PC3200 Value Select memory and they are generating many errors in phase 5 and 8 of memtest86. My PC keeps crashing when they are equipped. OS is Windows 2000 and is usually rock solid when equipped with the XMS line. I've tried a lot of troubleshoot but looks like RMA is the only thing for me to do now.

Can you tell me the CPU speed and it’s FSB as well? In addition, please tell me the bios settings you have set for both CPU and memory and any performance settings that you may have set?

[alexhanlei]

CPU speed is Athlon XP 3000+ and FSB is stock, 200MHz. The Motherboard is an Asus A7N8X-E Deluxe, performance setting is "Optimal", all other settings are automatically set, timing settings are 2.5-3-3-8 as of right now.

[RAM GUY]

Please try these settings:

With the A7N8X-E please set the FSB jumper to pins 2-3 with the modules in slots 2-3 and then reset or clear the bios and load setup defaults and set the Dim Voltage to 2.7 Volts and set the timings manually. Then please test the system with http://www.memtest.org.

CPU Freq: 200 MHz

Memory Frequency: 100%

Dim Voltage to 2.7 Volts

Resulting Frequency: 200 MHz

SDRAM CAS Latency: 2.5T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Row Precharge (tRP): 3T

SDRAM Active to Precharge Delay (tRAS): 8T

 

I have had 4 of these exact MB's and this is what had to be done and a few other's had some success disabling Spread Spectrum in the bios as well. I would take a look at http://www.asusforums.org as well in the AMD section.

If you still get errors please test the modules one at a time with http://www.memtest.org to be sure its not a failing module.
