I want to know if it is possible for an 8320 to run the same way that an 8350 does? By this I mean the same speed AND with the same power saving features, and same Turbo boost (from 4Ghz to 4.2Ghz).
You can easily make a 8320 run on 4.0 (depending if u got a decent chip)
I have the exact same setup as you but a worse PSU. My 8320 is running at 4.4 ghz with 1.35v (max 55c temp under 100% load about 45c whilst playing games)
I think 4.5 is doable with my chip without going overboard with the voltages (haven't tried yet) with my current cooler.
You should be able to reach 8350 Specs on air cooling so a Hyper 212 might be all you need, but if you want to go higher I hear that it's difficult to get the 8320 stable over 4.5 Ghz which is weird, but happened to my friend who tried clocking his 8320 over 4.5, as well as many people I've read online.
Any FX8320 will run at 4Ghz without even changeing its voltage from stock even a cheap 212 evo can run it at 4.5ghz(going higher than 4.1/4.2 may need more voltage)
Mine runing at stock volts at 4.1Ghz all you need to do is adjust the multiplier turn off power saveing or dont turn off power saveing modes depending if yiou whant the chip to run in power saveing modes or not when not in use.
i have prop. one of the worst chips, already needing .1.4V for 4.5ghz and with that reaching already 67°C socket and 55°C core temperature on a custom watercooling loop...
4.6ghz already need 1.43V wich are running over 60°C core temperature!
and yes, pump is working and thermal paste is applied correctly.
