CMD16GX3M4A2800C12 Issue with Asus Maximus VI Extreme and Intel Core i7-4770K


Recommended Posts

Hello everyone, I have a new computer build and I'm having some issues with it. I understand that the XMP timings for my RAM is too much for my CPU to handle even though my motherboard supports it. In addition I'm using the latest BIOS for my motherboard and latest drivers for my hardware. However, I'm not sure what timings I should use to have a stable gaming platform. I would appreciate any feedback or advice to help me come up with a solution. Here is my current problem.


Problem 1: Windows 7 crashes after about 10-15mins when I use two or four sticks of ram in my PC and set the Ai Overclock Tuner setting in the BIOS to XMP.


Problem 2: Windows 7 crashes while in a game for about 10 to 15 mins when I use all four sticks of ram in my PC and set the Ai Overclock Tuner setting in the BIOS to Manual /Auto.


Current Status: Windows 7 doesn't crash (as much) when I use two sticks of ram and set the Ai Overclock Tuner setting in the BIOS to manual.


*NOTE* I did run Memtest86+ with all four sticks of RAM for about 21hours straight and had no errors. Although, I do have another issue where my System won't keep the correct time after a few mins. of being on.

Do you have the latest BIOS for your MB?


I would expect the crashs at 2800mhz. That is a HUGE memory overclock for your system. I would try something more reasonable like 1866 or 2133mhz with DIMM voltage set to 1.65v.


I do have the latest BIOS installed on my motherboard. Last night, I installed all four sticks of RAM in to my motherboard and set the Ai Overclock Tuner to XMP. However, I changed the MHz to 1866 and it still crashed. So, I set it to 1600 MHz and it still crashed.


There was no blue screen, just a hard shutdown and it restarted on it's own. I had all the other settings set to Auto in my BIOS. I'm not sure what's causing it to crash. I haven't overclocked the CPU yet.
