memtest failure


Recommended Posts

I had a mem test failure till I removed one of twins, TWINX512 3200LLPT CMX256A 400Mhz. What can I do? Do I need to replace both or just one.

Not sure why it was advised to buy a pair Would a single upgrade be better than keeping a matching pair?


Thanks for any help you may offer, Todd

please make sure that you install the memory modules on either slots 1&3 or 2&3 and also have the latest BIOS installed for your MB, load Setup/optimized default settings and try the following BIOS settings;

TwinX1024 or TwinX512-3200LL

Softmenu Setup

CPU Freq: 200

DRAM Clock: 400

CPU/Memory ratio: 1:1

Memory or Dim Reference voltage: 2.7/2.75 Volts

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


Configure Dram timing by SPD: Disabled/User define

SDRAM CAS Latency: 2T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Row Precharge (tRP): 2T

SDRAM Active to Precharge Delay (tRAS): 6T

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!

pass 3, errors 4, errors ECC 0


TST 7, Pass 2, Failing Adress 0000e6f2aa0 - 230.1MB, good 76c0473a, Err-bits 00000002,

Count 4, Chan ,


Test 2 with other memory in slot 1 (no failures) as of pass #5



Ever since this occured my pc freezes on the splash screen, is there a wat to fix this?

Desperatly seeking help, Todd

Thanks for your help!

Please set the Dim Voltage to 2.7 Volts and test the modules again. If you still get errors! Please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it!

errors on bad mem (1 of 2) after pass 11, I shut it off after 200+ errors listed.


Can I replace the twin pack, or can only peplace the bad one?

I originally bought the twin pack because I heard it's better to have twins, can i get another twin pack? can i pay extra for an upgrade?

What do you suggest?

Thank You for all your help, you are greatly appreciated.

Please email Customer Service with your RMA# and ask to check the status or call them at 888-222-4346 and Dial "0".[/quote



I lost my RMA since I returned my Mem, I wish I would've thought of having it signed for upon receipt. I would hope to hear it was at least recieved. Is there anything I can do to be reassured. Thank You So Very Much Again, Todd

p.s. Where can I find a customer service email link? would that be the (warranty department) link?
