memory could not be "read"/Physical memory dump

Recommended Posts



I recently built a computer and used a pair of TwinX3200XL pro (2x512).

my mobo is a Gigabyte GA-K8NXP-SLi

my hd is a Maxtor DiamondMax 10 300gb SATA

my Processor - AMD 64 3000+

my graphics cards- 2x Gainward "goes Like Hell" Golden Sample GeForce 6600GT's.

My Problem - every now and then it will come up with an error message saying that 'the Memory could not be "read."' this doesn't actually cause any problems, however, now it has started crashing and giving me the BSOD saying: "Machine_check_exception...Begging Physical Memory Dump".

it comes up with teh BSOD message everytime i leave the computer idle for a few hours, and occasionally when i am playing games (only Half life 2).

please could you help me with this.

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 TwinX512-3200XL

Advanced Chipset Features (Ctrl + F1)

DRAM Clock: 400 MHz

Configure Dram timing by SPD: Disabled/User define

SDRAM CAS Latency: 2T

SDRAM RAS to CAS Delay (tRCD): 2T

SDRAM Row Precharge (tRP): 2T

SDRAM Active to Precharge Delay (tRAS): 5T

SDRAM Burst Length: 8

SDRAM Bank Interleave: 4/Auto/Enabled

SDRAM Command Rate: 1T

Frequency Voltage Control

CPU Freq: 200

Memory or Dim Reference voltage: 2.7/2.75 Volts (+.2)

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!

If memtest86 found no problems or errors on the memory, then I will suggest you to look at other hardware/peripherals installed on your system. I do not think the problem is coming from the memory modules!
