Computer crashes once ram-intensive programs are used.

So, I got a new computer the other day (Thursday) and I got it all set up but once i go to play a game (MW3) it crashes my whole computer. This also happens when I have multiple tabs open on mozilla firefox/nightly. I am unsure whether it is the mobo or memory, or if they are the culprit, if they aren't sorry for posting here.

When my computer crashes, the sound stutters, like it is replaying one sound constantly but then it moves to like 1 milisecond ahead, and replays that part of the sound over and over and so on. My computer completely freezes and I have to either A) Flip power switch on back of PSU or hit the small button on my tower for the restart. I ran Memtst86+ and i got 1 pass in 50 minutes, I plan on running it overnight to.

Specs:
i5-2500k @3.30gHz
GA-Z68AP-D3 mobo (gigabyte)
8 GB of Kingston ddr3 1600 mHz ram.
650W Corsair PSU
Nvidia GTS 450 vid card

Any feedback/help is appreciated! :D

  1. Also run Prime95 torture tests for a few hours. If Memtest86+ and Prime95 run fine, then test the video card.
  2. I have run Prime95 and it didn't have any errors and i tried MSI Kombuster and I passed 100% @ 62 degrees celsius.
  3. Manually set the RAM: Memory multiplier, CAS timings (use quick), same color DIMM slots, and don't use XMP. In some instances use Command Rate -> 2. Also, if the kit is 1.65v then set DRAM Voltage -> 1.64v.

    Thanks, I did all that and it stopped, for the most part... I can now play games and such but when I have a game like MW3 or CS:S minimized and havea few mozilla tabs open, my computer crashes. The sound no longer stutters if that affects it all.
  5. You need to make absolutely sure that the RAM isn't the issue. Decreases the memory speed to 1333 MHz to see if it resolves the issue. What Kingston kit do you have? Most kits are 1.65v which isn't ideal for your configuration.
  6. What EXACT Kingston set do you have? I prefer a link.

    Then I'll post the exact settings for your RAM + MOBO BIOS settings.
  7. Kingston HyperX Genesis 1.65v and i tried going down to 1333 didnt work.

    DDR3-1600 9-9-9-27-2N @ 1.65v

    First, 1.65v RAM isn't ideal for Sandy Bridge, 1.50v is recommended BUT I haven't seen or heard of it damaging the SB.

    DIMM Slots:
    CPU: | blank | RAM | blank | RAM | ; white DIMM slots

    BIOS:
    Load Optimized
    Extreme Memory Profile (X.M.P.) -> Disabled
    System Memory Multiplier -> 16 ; 16 * 100MHz = 1600 MHz
    DRAM Timing Selectable -> Quick
    CAS Latency Time -> 9
    tRCD -> 9
    tRP -> 9
    tRAS -> 27
    -
    Command Rate (CMD) -> 2
    -
    QPI/Vtt Voltage -> 1.15v~1.20v ; depends on stability
    DRAM Voltage -> 1.64v

    -
    PCH SATA Control Mode -> AHCI **

    Save & Exit = Yes

    Boot

    Windows verify AHCI divers are running. BIOS = AHCI <=> Start = 0 ; reference -> http://support.microsoft.com/kb/922976

    Manually set Start = 0 <or> run Fix It per link above.

    HOly crap thats lots of info! I will get back to you as soon as i do it, thanks for the fast response!
  10. Seems to be working, I will update if it stops.
  11. Cool! :sol:

    I'm keeping my fingers crossed.

    It crashed again >< but i went through, made sure i did everything. I noticed i hadnt switched sata to ACHI, when I did it would say "loading operating system" and about 2 lines of dots afterwards, it then restarted. So i switched it back and then I needed to restore it. Is the DVD suppsoed to boot after the HDD or before? AS of right now it is before the HDD.
  13. The AHCI is optional but it's faster so I 'thought' it's worth mentioning while you were in the BIOS. IDE is fine...

    Once I have a system running smoothly I make the OS drive the primary boot drive, use 'Quick Booting', turn-off (disable) unused ports/etc, and turn-off the Splash Screen or in some cases use a custom splash.
