I recently upgraded to an FX-8320e and am trying to stress test it prior to attempting any overclocking. I'm getting errors on various threads of the prime95 stress test. I'm using the small FFT test to basically keep the test to my CPU.

The computer keeps running, but various threads stop after a while with rounding errors or other "expect XYZ, got ZYX" errors. This takes about 20 minutes.

I'm currently running at stock speeds, stock voltage, etc. I reset my BIOS to "optimized defaults" before testing. (Cool 'n Quiet is on, as is turbo core, though that shouldn't be kicking in with this test.)

The rest of my system is as follows:
Gigabyte GA-78LMT-S2P (rev. 5.0 - BIOS version F4b)
EVGA 16GB DDR3-2133 (2 x 8 GB)
ASUS STRIX-GTX960-DC2OC-4GD5
Samsung Evo 840 250 GB SSD for main drive, and some assorted hard drives for others
Cooler Master RS-460-PMSR-A3
Cooler Master TX3 cooler

I don't think I'm coming anywhere near overheating. Core Temp is reporting about 36 C after a while at load, and AMD Overdrive is saying I have 34 C to go before the thermal ceiling.

Thanks!

Thanks. I didn't want to start playing with voltages yet, as it surprised me to have issues at stock.

I've got no issue using the stock cooler if that would perform better.

I'm also fine just leaving it as is and not trying any OC or anything, but I don't know if I need to be concerned about the errors in the test.

Yeah. I was trying to squeeze a little bit more out of my current setup. I had a Phenom 965 in there before, which shouldn't have even worked (it's not on the support list).

I was trying to avoid a motherboard change, due to all the reinstall commotion, and one of those situations where once you're buying a board, then you have to look at PSUs, and at that point, why not just go Intel, and costs balloon.
