Variation in CPU-Z readings due to BIOS settings on overclock voltage
Variation in CPU-Z readings due to BIOS settings on overclock voltage
Heya, in my signature I have the overclock listed, but my CPU and CPU/North Bridge LLC are set to high. The voltage is at stock levels (1.404 works fine for a 4.2 boost, barely affects performance). I'm running around 30-38°C, with some idle time showing only background apps, MSI Gaming App (Stock Gaming OC), Open Hardware and CPU-Z active. Voltage readings fluctuate between 1.416 and 1.428. No throttling even when under load (Prime95). Is this typical? Could it be the power supply issue?
that is just normal behavior during load changes and software voltage stepping calculations, seems typical to me. there is no vcore in between 1.416 and 1.428 you see, so the software simply chooses the nearest value between the two, even though the actual vcore is constantly fluctuating hundreds of times per second. you would notice this if you connected a good multimeter to it. evga 600w is exactly what you mentioned... and the only 600w power supply evga produces that I'm aware of is the 600b, which isn't particularly strong, especially for your setup. but that's not the cause of your vcore readings.

That's just typical behavior during load variations and voltage adjustment calculations, seems normal to me. There isn't a Vcore in between 1.416 and 1.428, so the software simply chooses the nearest value between those two, even though the actual Vcore is fluctuating hundreds of times per second. You'd notice this if you connected a good multimeter to it.
you can repurpose a quality power supply. choose a 650w evga g2, it comes with a 10-year warranty, offers ample power for any overclocked single cpu or gpu setup, and you can reuse the 600b for another machine or pair it with an fx8 core and a power-efficient GPU.
the 600b isn't terrible, it's actually reasonable compared to cheaper alternatives. however, when combined with your premium components and higher-wattage parts, it becomes less suitable and acts as the limiting factor.
