Random crashes


Recommended Posts



I have a stick of


CMX512 - 3200C2 XMS3202v3.1

0427081 - 0

XMS3200 512MB 400MHz CL2


That is the lable.


I don't really know a whole lot about any thing but here's the problem. I will boot up my computer and it will get all the way up, and then at random times it will just shut off and try to reboot. Somtimes it will reboot, sometimes it hangs up at random points in the procese. From time to time I get wierd messages from the OS I can't remeber them somthing like check sum error and a thing that go's through and checks my hard drives for errors, sometimes just a blue screen. Like I said I don't know much. I tested the ram with mem test. The times that it didn't crash mem test says nothing and other times upon restart there is no info from mem test cause its no longer running. I have also put the ram into another computer. It did not boot at all. This may be because the bus max's out at 333MHz However the ram form that computer will run the one that crashes with out any problems. That ram is only 333MHz and the chip is 400MHz. I don't know if that makes a differince. I not sure if its the ram or what it might be but if you think I sould rma or you have a suggestion to help me that would be great. Thanks

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?

The motherboard is a Soyo KT600 Dragon ultra (platinum edition)

The processor is an AMD Athlon XP 3200+ speed is 2.20GHz and the frontside bus is 400MHz

The BIOS is Phoenix - AwardBIOS

The System proformance is set to NORMAL

CPU frequency is set to 200MHz

The DRAM is set BY SPD. It shows


DRAM CAS Latency 2.5

Bank Inter leave DISABLED

Precharge to activate(trp) 3T

Trans Non-DDR400/DDR400 7T/10T

Active to CMD (Trcd) 3T

DRAM Burst Length 4

DRAM Command Rate 2T command

DRAM Access Time 3T

DRAM Queue Depth 4 level


Write recovery time 3T

AGP Performance normal

AGP Fast Write Disabled


as far as I know all the other settings in the BIOS are Default I have not changed anything. If you need anything else let me know. Thanks.

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

TwinX1024 or TwinX512-3200C2

CPU Freq: 200 MHz (400 FSB)

System Performance: User Define

Memory Frequency: 100%

Resulting Frequency: 200 MHz (400 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): 6T

SDRAM Command Rate: 1T

Bank Interleaving: 4 Banks

SDRAM Burst Length: 4 Beats

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!

Well I'm pretty sure that the ram is dead now. My system will not boot at all. I didn't even have the chance to change the settings that you suggested or run any more tests, it dosen't even boot to the BIOS. I can run the system with other ram. I tried to change the settings useing the other ram and it still woulden't boot with the XMS and then when I put the other ram in I got an error but I just reset the BIOS and everything went back to working. So I don't know. I think now I will need an RMA. I'm trying newegg now. I don't know if you give me RMA or what but the web site said to talk to you then talk to reseller so thats what I'm doing. Thanks.
