Prime95 one core failure
Prime95 one core failure
Running the test now, everything looks fine and I'm well over half through after an hour ten. It seems slower with a 16gb RAM, though. Haha
Looking into some research confirms my observations about timing being consistent in the BIOS for RAM. Still puzzled by how .5x leads to such issues. Also, after leaving the computer overnight at 4.01, the FFTS test got much hotter—from 54c to 63! I stopped quickly because it was concerning. What could cause such a big temperature rise without any changes?
Note: My log showed temperatures staying near 26°C with almost no variation during inactivity. That makes it hard to explain the sudden jump compared to the blend test.
The test ran for two hours without any issues. My RAM appears to be functioning correctly according to the manufacturer's specifications. I'm still puzzled about these readings. The minimum voltage needed for stability at 3.81 is 4.62500 with a .03 variation, and for 3.9 stability (lasting 2 hours) it should be around 1.472. It seems that 1.49 or 1.50 would be appropriate for stability. However, Prime95 doesn't seem to agree with this. I'm not sure what's going on.
As a side note; I went back to stock and was able to run 100% stable at only 1.33v with a .02 variance. My temps were AMAZING. 25c min 41c max. Really love this cooler, and as the clocks and cores go up with the build and size going down. I expect this cooler will last me through the end of the AM3+ series which is just getting off the ground! All in all I'm happy with my performance and heat. I will take what I can get and call it good. Afterall, a successful overclocker knows when the limit is reached, right? Then again, I have yet to move to clock tweaking. Any good guidance for taking what I have to make it better through clock tweaks?
Hey, just thinking about it again. Maybe my PSU isn't providing enough power? I checked some online calculators and found that my PSU's maximum rating matches what my computers are drawing. Could it be that the system is just being stressed too much? For example, pushing more power to the CPU during tests or load when memory isn't supplying enough, leading to failure because of the memory issue? Might the PSU itself be the problem?
Is there any method to evaluate a single core? It seems tricky in Prime95 configurations. [strike]I managed to launch Prime95 on designated cores via Task Manager and set the process affinity to run on 1 during the blend test. The two cores involved passed Test10, which gives me confidence the hardware is okay. This suggests the issue might be related to voltage settings. Adjust your LLC (load line calibration) in your BIOS to extremely high or ultra values—I encountered a similar situation where two cores failed but didn’t crash. LLC with assistance from VDroop and correcting core errors could help.
