Bad twinx1024-32000xlpt memory module


Recommended Posts

I believe one of my memory modules is bad. The system is:

  • Asus A8V-Deluxe (Via K8T800PRO)
  • Athlon 64 FX-55 (2600MHz)
  • TWINX1024-3200XLPT
  • Asus V9400-X/TD/64 video
  • Antec case with 350W power supply

Bios settings are defaults (no overclocking, standard voltages).


I am testing with Memtest 86+ v1.40


With DIMM A in slot A1, DIMM B in slot B1, I get multiple errors within 4 hours.

With DIMM A in slot A1, I don't get any errors reported in 24 hours.

With DIMM B in slot A1, I get multiple errors in 8 hours.


The results are the similiar if I use slots A2 and B2. The system won't boot if I have a single DIMM in slot A2 or B2.


What else should I try?

Please put the memory modules on either slots 1&3 or 2&4; make sure that you have the latest BIOS installed for your MB; load optimized/set up default, and set the following BIOS settings;

TwinX512 or TwinX1024-3200XL

Advanced CPU/Memory Configuration:

Memclock Mode: Limit

Memclock Value: 2:1 (DDR400)

Bank Interleaving: 4/Enabled

Burst Length: 8

SDRAM CAS Latency: 2T

SDRAM RAS to CAS Delay (tRCD): 2T

SDRAM Active to Precharge Delay (tRAS): 5T

SDRAM Row Precharge (tRP): 2T

2T Command Rate: Disabled

Jumper Free/Frequency Voltage Control:

AI Overclock Tuner: Manual

CPU FSB Clock: 200

DDR Voltage: 2.8 Volts

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

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!
