VS512MB400 Crashes memtest86--other same model sticks pass


Recommended Posts

I recently purchased my 3rd VS512MB400 from Canada Computers (March 05, 2005--DOP from receipt). After installation, my Debian Sarge (SID) box freezes after approximately 4 days with intermittent issues (segmentation faults during program startup [Mozilla Firefox, AbiWord, Bluefish, wxvlc, XMMS]--no others tried) throughout--Windows freezes after 9 minutes with the same hardware (just seems to stop).

 

I have 3 boxes:

I swapped out the DIMM (Lot# 0452074-1) with both my other DIMMs (Lot# 0437014-0 and Lot# 0416225-0) in Magma without incident (DIMMs were installed Sunday Evenings--lasting 7 days each). To be thorough, I downloaded and burned the latest version of memtest86 (v3.2 from http://www.memtest86.com/) and burnt it to a CD-RW.

 

I thought, "Hmm. Maybe this is a Linux issue."

 

I installed Lot# 0452074-1 in Magma and wiped out the partitions on /dev/sda then installed MS Windows 2000 SP1--the system halted after 9 minutes--even during install. I rebooted several times with the same results (eventually getting Windows to install). I installed SP4 and any other updates from Windows Update with the same results.

 

I installed Lot# 0452074-1 in Tsunami--using an old Western Digital Caviar 13GB ATA-66 IDE I had and rebooted with the Windows 2000 SP1 CD in the drive. The system halted after about 9 minutes--during the install.

 

I installed Lot# 0452074-1 in Eartuquake--using the Western Digital Caviar 13GB ATA-66 IDE and rebooted with the Windows 2000 SP1 CD in the drive. The system halted after about 9 minutes--during the install.

 

I powered Magma off (including the power supply) and inserted Lot# 0745204-1 in DDR0 and powered the system on--booting with the memtest86 CD--after 34,000+ errors (27% on the first pass), the program halted with an "Unexpected Interrupt" error.

 

I powered Magma off (including the power supply) and installed Lot# 0437014-0, then powered the system on--booting with the memtest86 CD--the test completed (running over-night) with 0 errors. I think I should note that this DIMM had previously been in Tsunami which had been up since September 13, 2004 without incident.

 

To be sure, I installed the third DIMM (Lot# 0416225-0) in Magma and repeated the test--again completed (running over-night) with 0 errors.

 

I was quite sure at this point that Lot# 0452074-1 was bad, but working in a tech support call centre I knew I had to be certain. I installed Lot# 0452074-1 in DDR0 of Earthquake (removing all other DIMMs) and booted normally (into Debian Sarge [sID])--again, it froze after about 4 days of use. I placed the memtest86 CD in /dev/hdc and--I terminated the test after 87,000+ errors (somewhere around 56% of the first pass).

 

I contacted the POP (point of purchase)--they said that because it's beyond 30 days from DOP (date of purchase), I would have to contact the manufacturer for support.

 

I'm quite certain at this point that I've got a bad DIMM. What I'd like to know is, if you agree?

 

If so, great--I will follow the procedures outlined elsewhere in these forums. If not, what have I missed?

 

In hope of a "yes, your DIMM is bad, we'll replace it",

I received my replacement module 10 days ago--I wanted to thoroughly test the RAM before I posted anything.

 

The replacement came a lot quicker than I expected and I've hammered the RAM for the past 10 days--it's working perfectly.

 

Thank you RAM Guy and Corsair!

 

Cheers!

Randall

 

P.S. Feel free to use this as a testimonial.
