randall_l Posted May 8, 2005 Share Posted May 8, 2005 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: Tsunami: Mobo: ECS Group K7S5A Proc: AMD Athlon XP 1600+ RAM: 1x 512MB DDR400 AzenRam (Infineon chips) in DDR0, 1x Corsair Value Select VS512MB400 Lot# 0416225-0 in DDR1 HDD: /dev/hda: Maxtor DiamondMax Plus 9 EIDE 160GB ATA-133 7200RPM 8MB; /dev/hdb: Maxtor diamondMax Plus 9 EIDE 160GB ATA-133 7200RPM 8MB Video: Generic NVIDIA Riva TNT2 M64 32MB OS: Debian Sarge (SID) - 2.6.10 kernel Duties: Firewall, NFS server, MythTV box (2x Hauppauge PVR-250) Earthquake: Mobo: Soltek SL-KT880E-RL Proc: AMD Athlon XP 3200+ RAM: 2x XXX PC-3200 DDR400 Premier Series 1GB (2x512MB) Dual Channel Kit CAS2.5 (XXX4001024PDC-K) HDD: /dev/sda: Western Digital Caviar SATA (WD2000JD) 200GB 7200RPM 8MB Buffer Video: MSI VTD256 NVIDIA GeForce FX5700 256MB OS: Debian Sarge (SID) - 2.6.10 kernel Duties: Primary PC - media playback, web browsing, gaming Magma: Mobo: ASUS A7V880 Proc: AMD Athlon XP 3200+ RAM: 2x Corsair Value Select VS512MB400 (Lot# 0437014-0 ind DDR0, Lot# 0745204-1 in DDR2) - Dual Channel mode HDD: /dev/sda: Western Digital Caviar SATA (WD2000JD) 200GB 7200RPM 8MB Buffer Video: ASUS V9520TD NVIDIA GeForce FX5200 128MB OS: Debian Sarge (SID) - 2.6.10 kernel Duties: Secondary PC - media playback, web browsing 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", Randall Link to comment Share on other sites More sharing options...

randall_l Posted June 3, 2005 Author Share Posted June 3, 2005 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.
