BAd Module

[SDANGE]

I recently purchased 2 VS512MB400 modules and now my pc will not boot with the suspect module installed in any of the RAM slots on my new ASUS P4P-800E Deluxe motherboard. I am looking for a warranty replacement. Thank you for your time.

Please make sure that you have the latest BIOS for your MB and load Setup/optimized default settings, and try the following BIOS settings;

VS1GBKIT400 or VS512MB400

Advanced/Jumper Free

AI over clocking: Manual

CPU Freq: 200

DRAM Clock: 400 MHz

Memory or Dim Reference voltage: 2.75 Volts

System performance: Auto

AGP Voltage: Default *unless you have ATI (9200 or 9600) or NVIDIA (5200 or 5700) then 1.6 Volts suggested!*

Advanced/Chipset

Configure Dram timing by SPD: Disabled/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): 8T

SDRAM Burst Length: 8

Memory Acceleration Mode: Auto

USB Legacy Support: Disabled

All other settings should be set to default settings!

Then please test them one at a time with http://www.memtest.org and let’s make sure it's not some other issue! I would run the test for at least 2-3 passes to be sure!

When the module in question is installed, the PC does not post. When I remove that module the PC functions fine. I did however use your recommendations for the BIOS settings and it didn't help.
