ASUS P5B-SE + Corsair CM2X1024-6400C4


Recommended Posts

I just a bought a new pc, with a ASUS P5B-SE motherboard, and CM2X1024-6400C4 memory.

And i am getting BSOD and crashes a lot.


I updated the BIOS, changed memery slots, run memtest (had a lot of errors.)


Now i found out that my motherboard doesnt support 2.1 V for the memory.

Only 1.9V (max). Any idea how can run my PC smoothly?

With the 4GB of memory system, you need to remove two sticks, setup your Vdimm to 2.1v, MCH (Northbridge) to 1.4V and the bandwidth lowered to 667 to facilitate the use of all four banks. Then install the second set. Restart.


This link might help you understand the issue. Please take your time when you go through it.


Edit: Link Fixed

With 4 modules I would suggest setting the memory frequency at DDR667 and set the memory Voltage to 2.0 Volts and set the timings manually to Cas 5-5-5-15 and TRC to 24 and write to precharge delay to 15 and test with http://www.memtest.org to make sure its stable but you also need to disable legacy USB when running any memory test on that MB.
