System Lock-Up When Using Dual Memory

Hello,

I have a Biostar Tseries TZ68A+ motherboard with 2x4GB sticks of Patriot RAM. Since I upgraded my computer to these parts (and a new graphics card and SSD) I have been experiencing at least one full system lockup requiring a hard reboot a day. These lockups don't display any error messages; the mouse and keyboard 'turn off,' whatever image is displaying on the monitor freezes, and the speakers emit a continuous noise till I reboot. These lock-ups are random and occur whether I am listening to music, browsing the web, playing a game, or the system is idle.

I have tested each stick of memory individually and everything was fine. When I put both sticks in again, the system crashed the same way almost immediately upon start-up. I assume this is therefore a motherboard problem, although I don't know quite enough about computers to rule out the problem being with the memory.

Hopefully I can find some help here, as Biostar's website (in broken English) did not fill me with confidence, although I did go ahead and email their tech support nevertheless.

Thanks,

Karl

  1. Your sticks have to be installed in slots DDR3_A2 & DDR3_B2
  2. They are. After I tested each stick individually, I put them both in again and I still get the same kind of lock-ups but they only occur immediately at start-up. Once I reboot the computer is fine for the rest of the day. I suppose that's a problem I can live with.
  3. Double check the memory specs. with the bios settings.
  4. What exactly should I be looking for? I have no clue when it comes to bios settings and the manual isn't very enlightening either.

    You cannot change your memory settings/timings with your particular motherboard.

    Bottom line is that your Patriot 4GB memory modules are not 100% compatible with your board. According to Biostar's website your board is only fully compatible with 1GB Patriot modules.

  6. Ah, well that's a bit annoying, especially because I bought the motherboard and memory on anandtech's recommendation (http://www.anandtech.com/show/4456/sandy-bridge-buyers-guide/4).

    As it stands now (crashing only a start-up), I can live with that. Thanks for the help, everyone.
