Memtest86 [cpu error]

[SirDickltin]

My computer has been acting up lately​. I've been getting BSoD saying memory management problem. So I decided to use memtest86 to see what was up. I get a message saying [cpu error] could not start CPU 0.
Does this mean it's my CPU not my ram?

It could be a combination of both issues with ram and cpu. It gets really complicated when its both the ram and cpu having issues with stability. It would be best to start the overclock over again for either the cpu or the ram. I would suggest setting your ram back to stock settings, or just a lower frequency and looser timings. Doing so would, hopefully, allow your ram to be stable again and allow us to look into the stability of your cpu.

You should then test cpu stability with prime95 and run smallFFTs (30-45mins will suffice to find major flaws). Any errors you get in smallFFTs will either result in the cpu usage being below 100% or an out right BSOD. You would need to increase your voltages to have the cpu become stable, as higher loads will result in a bigger drop in voltage (to the point where the cpu will not be supplied enough and will spit out errrors).

What did you set for your voltage for your cpu? I remember they said that 1.30V is the recommended max voltage for that generation of cpu. If your voltage is higher than 1.30V, it would be best to reduce it to that. And if your cpu is both unstable AND already over 1.30V, you may need to reduce your overclock a bit.

Once you have gotten your cpu stability cleared, you can proceed to doing Memtest again. As your ram should be at stock settings, or lower, memtest should show no errors. If all is fine, you can proceed to ramp up your ram frequency again, doing Memtest each time to test for stability.
