hi, got a bad ram module


Recommended Posts



i'm running an asus a7n8x deluxe board with an amd barton [333mhz] 2500+ and installed two cmx512-2700c2 sticks in dual channel mode about 6 months or so ago.


then i started experiencing some crashes but not right away and the post report would give me the occational bad ram error but upon reboot it was cleared, thought it was my vid card and replaced it [upgraded anyway]. then the crashes still were happening but it was so infrequent i thought it was simply a silly windows error but with some of the newer software i've been using [games] i've been experiencing alot of crashes and decided to finally memtest 86 my ram...


started in dual channel and ran the complete battery of tests for 100 passes and kepy getting errors in test 5 in the same memory area...


so i pulled one chip and tested in single channel mode and came up with errors in almost every pass of test 5, from one error a pass to 86 errors in a pass...


then i tested the other chip and it came up clean after 100 passes...


oh i ran the test with the optimal memory timings, 2-3-3-3-7


so i definatly have a bad ram chip, since only the one presents with errors in the number 5 memtest...


and going back to my reseller is more hassel than it's worth, would rather do this directly through the mail as i am disabled and in a wheelchair..


oh and my bios is the latest version and everythings up to date.


what do i do now?


fill out an rma form?


thanks for your reply in advance,

ok, filled out the RMA form...


will be waiting for a reply.


thank you and corsiar rocks!




edit: hey brivers! thought i recognised that handle...


how's it going? hehe 3 bad ram sticks? ouch!


funny thing about my bad ram is that ww2ol runs perfectly fine even though it's really suseptible [spelling?] to single bit memory errors, always has...


go figure!

Please make sure that you have the latest BIOS for your MB and load Setup/Optimized default settings, and try the following BIOS settings;


CPU Freq: 166 MHz (333 FSB)

System Performance: User Define

Memory Frequency: 100%

Resulting Frequency: 166 MHz (333 FSB)

Memory Timing: User Define

SDRAM CAS Latency: 2.5T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Row Precharge (tRP): 3T

SDRAM Active to Precharge Delay (tRAS): 7T

DDR Reference Voltage: 2.7 Volts

AGP Voltage: Default *unless you have ATI (9200 or 9600) or NVIDIA (5200 or 5700) then 1.6 Volts suggested!*

All other settings are motherboards defaults

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!

after i finally shipped my bad ram module [it got lost at the post office for like 2 weeks] and you guys got it. you sent me a working replacement within a day.


THANK YOU! your warranty policy is one of the best and has made me a corsair ram buyer for life.


one suggestion tho, an auto generated email giving the tracking number or at least that the ram was shipped would make the whole experience perfect. i missed my first attempt at delivery from UPS because i didn't realise it was shipped already and it actually arrived a day early! so i had to wait all of the 3 day weekend [due to new year's eve being a holiday] to get the ram...


ups provides a way to send other people the tracking info when sent, i realise this might take up a few extra minutes but it would make the whole experience with corsair absolutly perfect, even better than it awsomely is already...


thank you again!
