your temps are very high but its a good clockers, my temps are low and i have an okl clocker
@ Threepwood
Unstable at 5ghz, and would not boot and anything over 5ghz on 2 or 1 cores
insufficient water cooling
but there are going to be some changes soon

My voltage is 1.336 and it's on 4.6Ghz stable shall I put up? it crashes on 4.7ghz with the same voltage in prime.

Ah, shame. Can often get a couple of multipliers higher before further tweaking to stabilize.
It all depnds on your mobo, cooler and temps you get
I dont use prime, run a few tests with LinX, then game and use your system.
there is no situation where you PC is at 100% for hour's on end, i had a system running prime for 8hr then when i stopped prime and opened firefox i got a blue screen
I am now running 4.8Ghz @ 1.425v i will not be going and higher i am happy with that.
Just been gaming for 1hr and temp on the cores are 52 53 56 57. and now idleing at 30 28 32 32. That will do me just fine.

cough
* New case, tonnes of radiators *
cough
* setup, i want to attempt 5.5Ghz, as over time, a lot of people have been pushing the 2500K harder and harder 
well.... Turbo mode enabled, so 3.7Ghz 
well a new day brings a new addition to the clocking HEAT and lots of it.
Last night i was maxing out in the low 60's, this morning i decided to stress it a bit just so i know its 100% stable and i just hit 76c, and i am not happy with that. I did think my temps was very low but i just went along with it, all i can think is there was a bug of some sort.
as soon as the thermal paste starts to degrade, it wont stop
(unless you run very cold
)What thermal paste are you running and how old is it? as well, heat slowly kills the thermal paste, i can go up to 100.C before it starts to degrade.
Keep an eye outas soon as the thermal paste starts to degrade, it wont stop
(unless you run very cold
)
I am using EK stuff and its about 8 days old as i only just got the CPU.
I will buy some better stuff but i am getting a new case soon and didnt want to waist some expensive stuff
thats what you get from cheap CPU thermal paste.
Just finished stress testing using IBT. 4.8GHz at 1.435v was stable, 1.43v was not.
Using stooeh's suggestion to raise VCCT to 1.15 seems to have helped quite a bit.
Does anyone touch the PLL Voltage as mine is on auto and I don't really know what to do with it.

you can lower pll to 1.65v,it help slightly with temps and maybe less cpu voltage
Just PLLnot sure on msi boards
anything that shows 1.8v in bios?
