Defective RAM


Recommended Posts

I purchased a matching pair of RAM from Newegg last month. (2x512mb, ValueSelect, PC3200 - Part VS512MB400 Lot 0440029-0)


Everything was able to load correctly until I began running games. I had occasional lock-ups which required hard reboots. I thought it could possibly be the RAM and sure enough, after playing around with memtest for several hours, I found the bad stick.


I originally ran memtest overnight with both DIMMs installed and it found 31 errors in an 8 hour time span.


I then ran each DIMM individually and almost immediately one of the DIMMs showed errors. The other went through the test fine.


For the record, here are my other system specs:


AMD Athlon 64 3000+ (939)

MSI K8N Neo2 Platinum

ATI Radeon 9800pro

Antec Sonata (with 380w Antec Truepower PSU)

Seagate SATA 7200.7 80gb


All settings are stock with no overclock/changes. BIOS is updated to the latest revision (1.4 I believe).


Anything else I should try before RMAing??? Also, will I need to RMA both sticks since I purchased them as a twin pack? (I hope not, or I will be computerless for a while!)

Please make sure you have the latest BIOS installed in your MB and load optimized/optimal default settings, and try the following BIOS settings;

Advanced Chipset:

Memclock Mode: Manual (400)

Bank Interleaving: 4/Enabled

Burst Length: 4

SDRAM CAS Latency: 2.5T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Active to Precharge Delay (tRAS): 8T

SDRAM Row Precharge (tRP): 3T

Frequency Voltage Control:

Spread Spectrum: Enabled

CPU FSB Clock: 200

DDR Voltage: 2.7/2.75 Volts

All other settings should be set to default settings!

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!
