I think I may have a bad stick of RAM.

Recommended Posts

Well I have 2 sticks of corsair RAM. Once is a 256 stick and the other a 512 stick both are 266 mhz. Suddenly I started having random boots so I had Win Xp show me the error code and both error codes where due to bad ram according to win xp. I then downloaded memtest and ran both ram modules alone. The 512 stick gave me about 60 errors running the standard test which I ran for about 2 hours. I then ran the 256 stick for the same time and got no errors. I think my 512 stick may have gone bad. System specs are:


MB : Shuttle AN34[N] Ultra

Vid card: Sapphire 9600 XT

CPU: AMD 2400

On board sound, and LAN.


Edit: Forgot to put the RAM model :) for the stick that is not working.


Value Select





I also had problem running the Doom 3 demo when I had both sticks in the game would crash within 10 minutes of playing it. Once the 512 stick was removed the game ran for well over an hour with no problems. Thank you. :D:

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


CPU Freq: 133 MHz (266 FSB)

System Performance: User Define

Memory Frequency: 100%

Resulting Frequency: 133 MHz (266 FSB)

Memory Timing: 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

DDR Reference Voltage: 2.7 Volts

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

All other settings are motherboards defaults

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!

Ok so i updated my BIOS. I also set all the settings to that which you specified. I then ran Memtest86+ for each RAM module. I first ran the stick of 512 the one that was giving me problems. I got 59 error's in total from 3 passes.


Test 1: 6

Test 3: 11

Test 4: 42


I then ran the 256 stick for longer ( 16 passes ) and I got 0 error's.


I think I will have to RMA the stick of 512 RAM. Also those setting you gave me are those optimal settings for my RAM or are they simply testing settings? Thank you for your time.
