2 pairs of TWIN2X2048-8500C5D + Asus Crosshair II Formula = Problems ;)

Hi

 

I have the above mentioned motherboard and 4 sticks of memory.

Please note the revisions, it is in my specs.

Using my Asus motherboard none of them works, they all fail using Memtest 86+ version 2.11.

And they fail when installed individually, when installed in pairs and when they are all installed at once.

 

I have recently updated the motherboard to the most recent BIOS, 1703.

 

I have tested the four modules in another motherboard and they work just fine and I have also tested another module in my motherboard that works out fine as well.

The one working fine is a regular Corsair XMS2 6400C4 module.

 

What can I do to make these modules work?

I have tried giving them more voltage 2,2 V (didn't dare to go any higher) and I have also tested using default values in the bios. Nothing works out.

 

I am afraid I will have to get some new modules, but I have never experienced problems using Corsair memory before?

 

Btw the rig crash and burns when I try to activate the EPP optimizations, I have only tested this when OC'ing though, and it seems that it is a bad idea to activate it, when OC'ing. ;)

With 4 modules I would suggest setting the memory frequency at DDR667 or DDR800 and set the memory Voltage to 2.1 Volts and set the NB/MCH/SPP Voltage to +.2 Volts as well and test the system with http://www.memtest.org. In addition, with some MB's (Mostly ASUS) you have to disable legacy USB in the bios when running any memory test.

Hi

 

Sorry about the late reply.

But actually I ran into problems with my GFX as well, needed to get that sorted first.

Everything is working now, and I do not know why?

I am using four modules at 250 MHz right now, and they all pass memtest 86+ with flying colors.

I do not know what was wrong earlier, but no problems now.:p:
