Overclocking questions

Just an update. I decided to clean my computer today. It went from cleaning to rearranging the fans, adding a fan to the other side of the 212 EVO, 2 hours of pain in the ass and some ghetto rigging later and I'm at 64c socket after 10 minutes of OCCT. Also to note, I made some adjustments a week ago and I'm at 20.5 on the multiplier up from 20, I lowered the bus to ~216MHz, voltage set to 1.375 (1.368 actual idle and 1.344-1.356 actual under load), and LLC to High.This seems to give best performance compared to 20 on multiplier and 220MHz bus.

So now the temps are pretty good as far as a 212 EVO goes. BUT, if I wanted to overclock more, I'm going to need more voltage. It's already at the lowest voltage limit, If I raised anything, I would need to increase voltage. There's no point in raising it past 1.375 since it doesn't even reach that high, which leaves setting LLC to extreme. Is that even safe with my specs? Or is it best to call it a day at 4.4GHz and 64c socket temp under load?

I'm still curious to see what would happen if you pushed that bus speed higher, but LLC to extreme is fine as long as voltage is still happy under load. But the best performance to time/cost investment you could do is switch that TIM out to conductonaut, or at least kryonaut if your scared of liquid metal.

I just beat the national record with same cpu, smaller cooler, 22c ambient, same power supply like I had planned. 5th one down on this page.

haven't fine tuned it but if I put bus at 220MHz, it will blue screen under a stress test.

My bus was around my usual spot, 271.9MHz in this case, but it was a different motherboard.

Update: The reason I say switch paste, if your worried about that extra performance, is that these chips respond great to lowering temps, even if your chip before was unstable at say 60c 1.38v @ 4.5ghz (just an example), simply switching to liquid metal, because of the drops in temps, good chance you would be stable after the TIM swap w/o touching voltage. Not saying I recommend it in your case, but if you decide to go any further, I would definitely focus on TIM.

Won't be available for a while to respond.

That's a pretty good temperature on the 212, and your OC isn't bad either. I got more or less the same temps with an FX-9370 at 4.5GHz (205MHz bus, 22 multiplier) and 1.3875 vcore (which effectivle are 1.34v-135v in my LLC-less motherboard), but using a Kraken X60. I'm not surprised it is easier to get stability with lower bus speed, since even if the CPU speed ends up being the same, you distort the RAM speed less.

You can increase your voltage, and you'll get higher effective voltage, even if lower than the one you set. But temperatures would increase as well. You could handle a bit mroe than 64C socket, but for an everyday overclock, I'd settle for your current voltage settings, and see what is the best you can get stable with different bus and multiplier combinations, and then call it a day
