OCCT memory usuage hit 99 percent then system lock

Gphish · Dec 13, 2013

This morning starting playing BF4 as usual with no problems or crashes until now. When playing the crash makes all my system devices loose power until restart. When upon restart a BIO's error states that power surge detected and shut down or restart (forgot). Please enter setup to continue. SO I switched to BF3 for a while then it happened again.

I just used OCCT. I selected the PSU tab and clicked to run the benchmark. I left it on infinity. I used Logitech G19keyboard with display and used the cpu/ memory applet and EVGA precision to monitor. On the 65 sec mark I noticed memory usage peak to 99 percent that's when it did its thing. Now that I seen what happened the power supply didn't loose power nor did the M/B or CPU,GPU's or fans or Corsair LINK/Light. What did loose power was all external usb devices and it locked up where I had to restart.
.
Should I have had a lock as soon as I hit 99% with OCCT?
Does this sound like memory or PSU problem?

To test memory simply download memtest86+ burn it to the CD and run test for 12 hours if there dont come any error i will assist you after. Good Luck

Faruk Aksamija :

This only occurs in the PSU benchmark, the other benches use 99 percent memory/cpu and haven't crashed. Also this only occurs in BF4 and only been able to duplicate by using the PSU stress test on OCCT. Just try to eliminate other possibilities (which there are)before tying up my pc on a 12 hour test.

Well with memtest you will find out is your memory OK! if it fails that is the problem of lock ups. But if it pass it then your psu may be the problem. Can u say me what are your temparatures on idle and on stress/load test. Good Luck

OK, this morning I ran memtest86 version5.01. one pass took 2 hours and 3 minutes. Pass completed without errors running at 1866 Mhz.I took a pic of test results but seems you can post attachments. Im not surprised due to the issue only comes up on BF4/BF3 and only when I ran PSU stress test in OCCT.

I do have another power supply to use. It will take me a hour or two to switch out. After I do that ill try to play it again. But im worried I might screw that one up. My AX1200 now and HX1000 after that it too risky right? I can use my phone to respond to this thread.

Problem with psu can only be solved with changing it and testing.If you get same lock up again i will lead you throught more tests to finaly find out whats the problem.

Yes, it seems to have been the power supply. So far no issues.

Yeah PSU is one of the main factors of lock-ups. There is many cases why acutally PSU go bad. One of them is bad electricity installations, heat or 24/7 pc usage. I am really happy that you have fix that problem Good Luck!
