M2N-E SLI and TWIN2X2048-6400C4DHX not working


Recommended Posts

Dear all,


I having difficulty enabling my freshly purchased modules in my mb.


Here is the mobo:

Asus M2N-E SLI

Corsair 2x1GB DDR2 SDRAM PC6400 CL4.0 TwinX Dominator (TWIN2X2048-6400C4DHX)


This is what happens when plugging in the modules (same colour slots):

1 Computer starts up

2 An audio warning occurs before even seeing anything on the screen

3 1x long, 2x short (repeating)


I guess this means a memory fault


This is what I have already tried:

1 All possible positions and combo's

2 Bios update


-no result-

The "old" memory workes just fine (also corsair, but simple module).


What should I do?

These 6400C4's are high end modules and need more voltage than the lower end throughput modules.


Set your old modules into the motherboard. Enter the BIOS and set:


Jumperfree Configuration:


AI Tuning: Manual

DDR Voltage Control: 2.1V

Memory Configuration:


Memory Clock Frequency: Manual

Memclock Value: 800Mhz

TCL: 4


TRP: 4

TRAS: 12

1T/2T Memory Timing: 2T

Ok here's what i've done:


I have followed your first advice and entered all the settings in the Bios and restarted with new modules. No luck.


Then I have started with old modules and loaded setup defaults. Saved it and restarted with modules. No luck.


I am getting the fealing that I should request an RMA with my supplier :[pouts:

Hi Ram Guy,


I just received approval for a RMA from the store I bought the modules from. This would save us some shipping costs :biggrin:


I have seen that another topic was started for the same motherboard regarding the best modules to use, so I will post my comments there...


Thanks for the support!
