Error verifying data in RAM

[soomingooi]

Hi, I'm running the memory test (on DDR3) and i got a few errors after running for a couple of days.
From the log files, it doesn't provide me with any fail memory location or the data read and expected so i have no way to check which bit (data line) is giving me problem.
Is there a way to get more information out of the error log?

I've rerun the test with memtest86+ and i didn't see any failure at all, after running it for the same amount of days. Is that means burintest is more stressful that i can see the error but not on memtest86+?


Please help.

One more question is that can the Error verifying data in RAM caused by something other than the memory itself?

If you enable activity trace level 1 in the logging options there should be more information logged about the error when it occurs.

BurnInTest and Memtest often display errors the other doesn't, other factors such as CPU load and system heat can contribute to errors. There are several other posts on the forum regarding memory errors;
