Balanced is really snappy, considering idle ~0.1-0.7vcore instead of >1.3vcore, seems no reason not to use it. I did not see any evidence of it affecting any of my benchmarks or games in an at all really notable way yet, though i ran high performance when i was squeezing individual points out of cinebench when running it from idle cpu state (1 point is nearly 1/10'th of a percent at this point)

I run Adaptive with no C states and High Performance with min. CPU @ 5% to max everything, while getting the nice drop to 0.7v and lower clocks. I don't care about the 0.1v whatever.

Back up and running.

I believe I might have to rma the psu now as cpu led hangs during POST now. So, since I won't be using any kind of sleep/hybrid sleep settings with the haswell, it should be fine to use an older, noncertified psu right?
C-states shouldn't pose any issue?

I'll have to check here in a bit, but I believe default setting on this board is disabled c6/7. Enabled 3, maybe. That's the only issue if I remember correctly, certified haswell for the low draw sleepy modes.

I forced C6/C7 on, made sure my PC could idle on my cheap PSU. Turns out it could so I keep it like that. Keeps the UPS running for a lot longer than portrayed on the web with the power savings.

Would I need to increase the input voltage if i am increasing the uncore cache voltage to 1.2? (default input voltage is at 1.79v) my vcore is at 1.23 stable and since im ocing the uncore i figured i might need to increase the input? maybe to 1.85-1.90?

Maybe a tiny bit

edit: forgot to post cpu-z


what should i do next? up my uncore or the core?
