worth overclocking ?

Thats basically what i do for a 24/7 OC. Without the cut back bit, once i hit the 70, thats where i leave it.
My mobo warns me if i go over 90c, which is really handy because i will always know if my temps are getting to high

Not knowing what your ambient temp is I cannot say what to aim for, which is why I said <40c Delta, if your current temp is 15c and you overclock to 70c then that's too hot, if your ambient is 35c and you overclock to 70c then you should be fine, hope that makes it clearer.

1.2v @ 56c seems about normal so as long as you keep below 1.4v see how far you go, check ambient and compare to CPU temp to get delta and if it's less then 40 you should be fine.

Remember Prime does generate allot more heat then pretty much any other app so 40 delta is rule of thumb not definitive, you can creep over a bit if you want to.

Okay so i found a good guide i wanna follow but he refers to his LLC as a percentage and in my bios it's only got levels, so i tried to google it but i failed.
anyone know what is the corresponding LLC im looking for 75%

Alright well i ran 4.4ghz @ 1.24Vcore with a LLC of level 7 and was seemingly running stable (didn't test for extended time)
but the temps where higher then i liked 73-75 @ 100% load soooo i basically stopped it n thought id try for lower temps

and well i noticed that the Vcore was actually going to 1.3X something and i assumed this was due to the LLC
so i was like okay maybe bringing down the LLC will help to stop the Vcore going up under load so i put it down to level 1
and well then my computer wouldn't start up so it eventually reverted itself back to stock so it could start.

i read a guide where the guy some how managed to get 4.5 with stock Vcore using 75 % LLC
so basically either my cooling just isn't cutting it or maybe i'm getting this LLC thing wrong or
he left out some minor detail i'm missing.

It seems with my setup if i have to go to 1.3vcore i will most likely get temps i will not be happy with

[Brianf1971]

LLC is Load Line Calibration and it won't help heat, in fact it can raise it a bit if set too high, what it does is maintains steady voltage to avoid voltage droop on the Vcore, the higher the level the tighter the voltage (less fluctuation in voltage closer the what you set).

You used arctic silver 5 didn't you, if so remember there is a burn in cure period, I would set the clocks to stock and run 10hour Prime before overclocking on AC5.

At that point it should be set and you should get accurate temps.

Cheers for the Brain for the info

yeah its Arctic silver 5, also the amount i applied i think is normal but seeing as i've never seen how much anyone else puts on i've never been sure if i have been doing it right, maybe i should double check haha. but yeah ill burn it in and then try again.

Any idea if its normal for my Vcore to fluctuate to 1.33ish even though i had it set to 1.24 and running 4.4ghz @ about 75 degrees? i wanna minimize the Vcore to lessen the Temp and keep as much life to the cpu as possible

[Brianf1971]

1.33 isn't going to shorten the life chip max is around 1.5 from memory (it's actually a combination of heat and volts which is why LN2 & Watercooled can go higher on volts), I don't know your board but usually a lower number = higher LLC, check your manual, my experience is do not use the highest LLC go one down from that.

As to the paste there are allot of different opinions, most test show less is more, therefore a smallish blob the size of a grain of rice in the middle is usually best, however applying paste has been shown to make 2-3c diff only, burn in AC5 has been shown to make around 5c diff, combine the 2 and you could shave a decent amount off your temps, get better paste and a little more.

The biggest change your going to see in temps is upgrading your cooler, going to NH-D14 (comes with better paste) or H100 could drop 10-15c.

Combining all of the above you could see up to 20c drop in your load temps, this is not a guarantee mind you but you will drop heat following any/all of the above.

Edit : I'm not sure your home made mount is helping you (are you still using the supplied retention bracket), you need a firm amount of downforce, and while your case may not have cable management good airflow is also essential in air cooling system, make sure there is direct flow from the intake to the cooler, usually 2 intake fans in front, 1 rear exhaust at a min, if you can an extra exhaust on top would also help, if your power supply is there make sure the intake fan faces down, tie as much cable out of the way as you can, and adding an extra fan to cooler may also help.
