Bad Ram Module CMX5123500C2


Recommended Posts

Ram Guy,


I have an apparent Ram Module CMX5123500C2 gone bad. I have had this part for about 2 years (Same Config., No Problems, No Changes) with no problems.


It recently started crashing in Flight Sim Application.

Is also randomly failing power on self test with Asus A78NX Board

Also is showing errors in Mem86 testing.


Can I get an exchange replacement module please?

Can you tell me how many modules you have and 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?

CPU Freq: 166 MHz

System Performance: User Define

Memory Frequency: 100%

Dim Voltage to 2.7 Volts

Resulting Frequency: 166MHz

Memory Timings: Manual/User Define

SDRAM CAS Latency: 2T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Row Precharge (tRP): 2T

SDRAM Active to Precharge Delay (tRAS): 6T

And test the modules one at a time with http://www.memtest.org, and since you were over clocking I would suggest setting the memory voltage at 2.8 Volts and you might add a few tenths of a volt to your CPU as well.

166 vs 200?


RAM Guy,


I will follow your direction here and adjust some settings, however,


Are you suggesting/implying that I should not over-clock. If so, why did I purchase RAM (Expensive) that is designed to handle OC?


I am not trying to be sarcastic here, but I truly am confused by the 166 reply specs.


I also wonder why the problems now, when this configuration has run fine for 2 years. The problem seems to manifest itself now when stressing the system with heavy graphics use, i.e. Flight Sim, etc.


I forgot to mention I am using an ATI Radeon 9800 Video Card.
