System stability test fail

[dumpa]

PC in the signature. I'm using AIDA64 stress test and have a strange problem. I can select all of the tests at once and the system will lock up in about 3-5 min after slowly becoming less and less responsive. Every time. If I select every test BUT the "Stress Cache", the test can run for hours just fine. I can also only select "Stress Cache" and run that test with no issues. It locks up only if I combine this test with other tests. Otherwise I have no issues with the PC. Besides not being impressed by the performance/cost ratio. Any ideas? Thanks

I've never run all at once...cpu/fpu/cache/memory for cpu and ram, the rest i run alone.

I wouldn't worry about it if it's already stable for your uses.

I'm unable to run cpu/fpu/cache/memory without it locking up. Strangely, individual tests do just fine.

That's at stock with expo enabled only? Weird. Is it stable for your uses?

Running at 6400. Stable otherwise. Just want to eliminate any potential hardware issue before the return period expires. Thanks again.
