MSI K9N SLI Platinum + 4 modules of Twin2x20486400C4


Recommended Posts


at first sorry for any language mistakes... ^^


I have a Problem with my computer system. I have upgraded my mainboard with 2 new memory modules and my system gets very unstable. I got some bluescreens (INTERNAL_POWER_ERROR, IRQ_NOT_LESS_OR_EQUAL and the undifined STOP ERROR) and I decided to reinstall my os. But the setup fails to. I tried to strip down my system that only The Mainboard, CPU, Memory, HDD, GPU, and DVD was pluged in (I thought that my PSU my isnt strong enough) but the Bluescreens didnt stop.

Then I decided to remove two of the memory modules and YEAH system runs fine. I changed them so that I tried the "old" and the "new" and both are running fine. Only if all memory modules are inserted the system runs very unstable.


I had a colseup on the memorymodules and noticed that they have two different versions 2.1 and 3.1 ... Is that maybe the problem ?


Mainboard settings are at default.

Memory is inserted right (old and new memory is not crossed in banks).


At last my system specs:

I would try setting your Memory (Vdimm) voltage to 2.1V. If that does not work, then you probably need to set your Dram bandwidth to 667Mhz. This is because most motherboards/bios's are not yet optimized to run at full Dram speed with four Dimms. Usually you have to drop a speed bin or raise timings (or both) to get a system with all four ranks populated to work.


Test for stability with Memtest http://www.memtest.org


Set Ram to 2.1Volts and test for stability. If unstable, then set Ram bandwidth to 667Mhz and retest for stability.
