TWIN2X2048-6400G some errors with memtest


Recommended Posts



I've got an E6600,

P5N E-SLI motherboard

8800 GTX

PSU HPU-4B-580-MU.

Bios is version 803.


I have tested my system 2 days ago with the bios setting 5-5-5-18 at 1.8v.

I have got a set of errors(500-600) at 98% of test5 after 8 minutes.


I have tested it also one day ago with as setting 5-5-5-12 at 2.013V during 10 hours. I have got around 20 errors for 20 complete tests.


I have tested it today with as setting 5-5-5-18 at 2.013 v an my proc overclocked to 2.7 ghz. Test has been running for 10 hours. I have got 10 errors.


This pair of memory is the second one I have. With the first one, I have got an average of one error every 3 seconds with standard settings from the



SO, can you please give a hand and tell what I have to modify, to test or to read ?

Please make sure that you have the latest bios and load setup defaults and then set the memory Voltage to 2.0 Volts then set the timings manually to the tested settings for the specific module you have, and test the modules one at a time with http://www.memtest.org to be sure one is not failing. 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! However, if you get errors with both modules that would suggest some other problem and I would test them in another system or MB to be sure. In addition, with some MB's (Mostly ASUS) you have to disable legacy USB in the bios when running any memory test.


Please not with this MB you will also need to set Command Rate to 2T manually and set the TRC if it's listed to 24.

Many thanks for your quick reply.


Today, I have reset the bios and set the timing to 5-5-5-12 2T 24 tRC and 2.013V. I have run memtest during 12 hours for 27 runs. I have got 11 errors of type 5.


What should I do next ?

Hi Ram Guy,


many thanks for you quick reply. I have brought back the memories to the shop I bought them. They have replaced them without any problem.


If you want, you can close Tech Support Express Case [408346] and RMA #1043254 as a solution has been found.


Best regards,
