memory causes crashes


neuen

Recommended Posts

Ive got a great computer but my Corsair ram just doesnt want to work right. While playing full screen games i get frequent crashes with and without the "memory could not be read" error. The ram is VS1GB400C3 and it is two sticks of 512 ram 2.5T and 200 fsb. When running at that speed i get crazy errors and it fails memtest while set to 8 3 3 2.5 200FSB, 11 3 3 2.5 200FSB, and at both those timings with 166 FSB. I dont know what to do. I lowered it down to 8 3 3 3T 166FSB and got no errors but i still crashed but i get a "cannot be 'written'" error.

Any ideas would be great thx in advance.

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?

Ever since i have installed the VS1GB400 set my computer has been experiences memory crashes. I will be in the middle of a program when the program will crash giving me an error, "The memory could not be 'read'". I get these errors when set on the the default 200FSB 7 3 3 2.5. I don't know if u need any more information if so tell me.

ok lets see here

Motherboard:Asus A78NX-Deluxe

CPU: AMD XP 2400

RAM: VS1GB400 (I was mistaken when i said it was VS1GB400C3)

FSB: 200Mhz

Multiplier: 11x

Memory Frequency: 100%

Memory Timings: 8 3 3 2.5

FSB Spread Spectrum: Disabled

AGP Spread Spectrum: Disabled

Cpu Volt: 1.650V

DDR Reference: 2.6V

AGP VDDQ Voltage: 1.5V

System Bios Cacheable: Disabled

Video Ram Cacheable: Disabled

tell me if there is anything else

im basically looking for an RMA unless u can think of a way to make em work

First thing, our hours are Monday Thru Friday Excluding Holidays 8:30 AM to 5:30 PM pacific time. That’s why your post has not been replied too. And that might be too much of an over clock for that CPU, please make sure that you have the latest bios and then load setup defaults and set these settings and test the modules one at a time with http://www.memtest.org.

CPU Freq: 133 MHz

Memory Frequency: 125%

Dim Voltage to 2.7 Volts

Resulting Frequency: 166MHz

SDRAM CAS Latency: 2.5T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Row Precharge (tRP): 3T

SDRAM Active to Precharge Delay (tRAS): 7T

alright ill give that a try thx for responding and sry didnt realize u werent working :P

 

edit: do you think that memtest would fail (because it did fail on the setting above very badly) if they cpu was too overclocked?

well it still doesnt seem to want to work at 133 FSB but i tried it at 166 with 12.5x and set memory to the settings u recomended and got no errors in memtest and no crashes so far. Although this ram is still suppost to run at 3200 not 2800 but i havnt tried it yet with the lower CPU FSB so maybe it will work now. :) I will let you know if it works. And if you have an idea how to get it back to the default 2400 settings that would be great but it doesnt register under auto as a 2400 but as like an 800Mhz.

No, if you have a 133/166 FSB CPU the memory speed should be set to DDR333. If you run the memory out of sync with your CPU it will cause a bottelneck in the chipset and may generate errors that are not the fault of the memory.
