Bad modules (Twinx 2x256MB 3200 Low Latency)

Recommended Posts

Hi,

 

I think I have a pair of bad twinx CMX256A - 3200LLPT (x2).

My computer reboots sometime alone.

I tested a couple of times with Memtest86 and there are two failing addresses detected:

0x00015f65700 abd 0x0000201cbd8.

 

I recently bought another pair of twinx of the same model.

I replaced the "apparently failing modules" and launched a couple of tests under Memtest86. NO ERROR.

 

To me, this suggests that the first two modules are bad.

 

What should I do? (proceed with a RMA?).

 

I have already contacted the reseller from whom I purchased but since the purchase occured more than 1 year ago, he invited me to contact the Corsair support directly.

 

Thank you for your help.

Can you tell me the make and model of MB you have along with 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?

Can you tell me the make and model of MB you have along with 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?

 

Here the details:

 

Motherboard:

Asustek P4P800

CPU speed 2.6Ghz FSB800 (it's a P4 2.6Ghz 'C')

 

Everything is set to default in the BIOS (no performance settings, no overclocking)

 

CPU External Frequency 200Mhz

DRAM Frequency [AUTO]

CPU VCore voltage [AUTO]

DDR Reference Voltage [AUTO]

 

Ratio = 13

Hyperthreading technology [Enabled]

 

DRAM Timing is choosen by SPD and is 2.5-3-2-6

 

As advised by friends, I tried to modify DDR Reference Voltage to 2.65V but this does not change anything in the Memtest86 tests.

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

TwinX1024 or TwinX512-3200C2

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: 2T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Row Precharge (tRP): 3T

SDRAM Active to Precharge Delay (tRAS): 6T

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!

I installed the latest BIOS for my Asus P4P800 (Bios 1019) and tried your suggested settings. I ran the tests under memtest (more than 3 passes).

The results are the same.

 

With my new "Twinx" modules, I have no error.

With the suspicious ones, there are always the same errors.

 

Do those tests confirm that I have bad modules?

 

Thank you.
