Please help: Computer Freezing constantly

Hi everyone,

I built my first computer but I seem to be having a problem.

When I put in both ram in dual channel (dimm2 and 4), my computer freezes completely (mouse and keyboard lock up too) after approx 10 mins of use, no matter what i'm doing.

I've ran memtest on each ram individually (in dimm 2 for 12+ hours) and found no errors.

I then began testing the computer with Intel Burn Test, with different configs of ram. (each time the results column has been the same numbers).

These are the tests I ran (including intel burns
a) ram 1 in slot 2 (no freeze)
b) ram 1 in slot 4 (no freeze)
c) ram 2 in slot 2 (froze twice, but couldn't re-create it with several more tries)
d) ram 2 in slot 4 (3 tries; 2 freeze, 1 went a long time with no freeze)
e) ram 1 in slot 2, ram 2 in slot 4 (always freezes after 5-10 minutes)

I'm new to building computers, so this is baffling me considerably. Based on what has been occurring, I would blame RAM 2 for causing all these problems, but I ran it through memtest and nothing showed up.

(Note 1: When first trying to instal windows, i had both ram in dual channel mode slots 2 and 4, it froze on me every time, i then removed am 2 from stick 4 and installed easily on the first time with ram 1 in slot 2)

(Note 2: When i first ran memtest i had the ram in dual channel mode, and my computer shut down partway through memtest (2 hours in), then restarted by itself, then shut down again)

(Note 3: I also adjusted the settings for the ram in the BIOS, the numbers were not correct in the default or XML profile, so i manually set the ram to be 1600mhz, 1.5v, 9-9-9-24, and the command rate to 2.)

I have checked HWMonitor, and voltages seem to be good, temps are great, (26 min for idle cpu, 70 max when running intel burn test, and the CPU passes testing every time with no problems, even on high for 20 passes.

What could it be? please help.

Thank you.

  1. First of provide the serial/part number of the RAMs. have you tried Dual Channel 1,3? Apparently RAM2 seems faulty but can't jump to conclusion.

    Ram is G.Skill Ripjaws X F3-12800CL9D-8GBXL

    I have not tried Dual Channel 1,3. The user manual of the MSI z87 G45 (pg 29 here: http://www.manualrepubliccdn.com/pdf/msi/msi-z87-g45-gaming-owner-s-manual.pdf) shows an image of Dimm slots 2 & 4 populated for dual Channel, or all 4 slots populated. I may be misinterpreting this though.

    Dear,

    Populate the first dual channel (1,3 slots) and report back pl.
