2 pairs of TWIN2X4096-6400C4DHX


Recommended Posts

Hi, I installed 2 pairs of this Ram on my P45 NEO 2 FR, but my system detect only 6go. I test all memory on all slot and that's the same problem.

I am a real noob with my Bios. I just put Voltage of my Ram to 2.1V.

I don't know what is the NB/MCH/SPP to configure +.2v and where to find its in bios. To lower frequency to 667, it s the same. I don't know to do that. (I saw that in previous topics)


Have you got an idea?

Sorry for my english, it's too poor.

With 4 modules I would suggest setting the memory frequency at DDR667 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.


And NB = North Bridge, MCH = Memory Controller Hub, SPP = System Platform Processor, depending on the chipset the setting may be any one of these or a combination of the above IE NB MCH Intel or NB SPP for Nvidia.
