bad TWINX512-3200XL modules

Recommended Posts

Under stress (i.e. gaming for 15minutes ca) my computer crashes. I've performed several Memtest runs and thousands of errors where detected. Currently i'm running on slower timings (3-3-4) in order to improve stability in normal "office-use". I'm sure the parts are defect; i've never overclocked them or exposed them to high physical stress.

 

Do i really have to send them to the USA? I live in germany and it's not that cheap to send them over there; isn't there a distribution center of some kind in europe?

 

thanks for any held, washed

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?

sry for the incredibly long delay.

 

The specs you requested:

 

ASUS P4C800 Deluxe

Pentium 4 3,0GHz Northwood (1MB L2 Cache) 800MHz FSB

BIOS Version: 1019

 

Settings:

 

Memory on SPD-Settings

PAT activated

Performance mode: turbo (it fails in normal mode, too)

Please try these settings after you load setup defaults.

AI Over Clock Tuner: Manual

CPU Freq: 200 MHz

Memory Frequency: 100%/DDR400

System Performance: Auto

Dim Voltage to 2.75 Volts (but if you over clock 2.85 Volts)

Resulting Frequency: 200MHz/400DDR

Legacy USB: Disabled

PAM/PAT/MAM: Auto

SDRAM CAS Latency: 2T

SDRAM RAS to CAS Delay (tRCD): 2T

SDRAM Row Precharge (tRP): 2T

SDRAM Active to Precharge Delay (tRAS): 5T

Then test the modules one at a time with http://www.memtest.org. And if you over clock the CPU it would be best to relax the timings to like Cass 2.5-3-3-7 and set the Voltage to 2.85 Volts and then increase the CPU Freq a few MHz at a time and see where it tops out then tweak the settings to enhance the performance. But using http://www.memtest.org to verify your settings are not causing errors.

Ok, I performed the test exactly the way you told me, here are the results:

L1 Cache: 8K 20969MB/s

L2 Cache: 512K 20969MB/s

Memory: 255M 1697MB/s

Chipset: Intel i875P (ECC: Disabled) FSB: 199MHz PAT: Disabled

Settings: RAM: 199MHz (DDR398) / CAS: 2-2-2-5 / Single Channel (64 Bits)
