got my shiny dh-d14 not new 2 OC but never with a good cooler (:

any ways i got hard time's getting 4.8 2 work stable it's almost there crash after 1H+ of prime

volt's

4800.jpg

and vram

4800vram.jpg

am a little scared 2 go over 1.42 under load it can go as far as 1.43 juice the volt's more even although temp's r just scratching 70's

any ideas ?

well love reference that explain in detail all the bios option's btw

I wouldnt go higher then 1.4v. Even if the temps are fine...

Totally agree with you.

Maybe you can back down on the OC to around 4.6 - 4.7GHz and the voltage needed.
 
temps around 70s at 4.8? That seems a bit high to me bro. But just personal preferences i guess. My temps dont reach over 47c at load running 4.9 with 1.42 volts thats with a 33-35c idle. But it may just be the chip, if you want that high of a 24/7oc you might just like everybody else say need to be okay with running those volts. Or just stick with what you are getting now as that is pretty good in its self.

I think it's because your watercooling and he's using a NH D-14. 70 C is very good for a 4.8 OC on an air cooler though. Personally, I like to keep temperatures below 65 and Intel recommend not using anything above 1.38 - 1.4 V.

Yup, totally different area when it comes to watercooling. 70°C is reasonable for an OC ~4.8GHz with the high voltage. It boils down to whether or not you will want to keep these temperatures hypothetically in a worse case situation.

just 2 make things clear for may self

wen u talk abut volt's u mean the settings on the bios

or the actual reading from monitoring software under load with "load-line calibration" active ?

any ways' i made ""big"" changes

the stability problem solved bay setting VCCIO 2 1.2V but it caused frequency dancing so got PLL set 2 1.8125 fixed
cool.gif


also i removed the OC from ram just in case when am testing ....

for now prime runs for almost 2H with CPU volt set 2 1.39V , under load CPUZ show 1.414v (used 2 b 1.435 at previous setting's)

temp's went up it's maxing 73c instead of 71c

am not going 2 stress my CPU , most of these system work is playing rift and it cant stress the CPU at all

but it seem's that the more i OC the more FPS i get , weird crappy program i guess ...

so temp's even if reach 80's in prime whont b a problem for my need's just worried abut long term damage from the volt's TBH

safe enough for 24/7 or i should just give up on 4.8ghz ? ):
 
I would personally give up on 4.8GHz considering the volts your putting through the CPU. I would leave it at 4.5 - 4.6GHz at a voltage level lower than 1.38 with the CPU temperature below or at 65 C. The higher temps will most likely limit the lifespan of the CPU, but if you are looking to replace your CPU/motherboard every 2/3 years I wouldn't be too worried about the CPU hitting 73 C at its hottest core. If you want to keep the CPU long term (5+ years) then a lower voltage level/CPU speed would be ideal.

Yup, that's a great explaination. I totally agree.

Okay thanks a lot for all the help decided 2 go with 4.8ghz

am assuming ill change system 2 x79 basic one in 2-3 years any ways'

further twik'd the voltage and got a really good vdrop setup so it's fairly solid at 1.385v and 1.390v under load

use load line calibration on ultra high instead of extreme

and manually added volt's for turbo setting's under CPU power management ....
blink.gif


over night test Aida log'd only one change 2 1.393 all the rest of the time 1.390-1.389 temp's still 73c ...

and i did needed 2 get a 2 fan's blowing on the mbord from and back and front of the bord

it got fairly hot under load S:

foolish wen u think of it using turbo volt settings' 2 handle vdrop

the bios should allow u 2 set load-line calibration better S:

next time ill buy a better board so i don't need 2 play so much 2 get volt's stable that board is horrible honestly

well the board diode didn't show any thin over 35c but wen i touch

the the heat sink it felt really bad (hot) now it feel's okay

and over night test log show nothing over 32c

Cool OK. As long as the heat sink is not hot enough to cause damage when touched it should be OK. You said your going to upgrade in a couple of years so your components should last you that long

decreasing cpu pll will help in some cases..

also what are your vrm settings? (switching frequencies and such)

i recommend:

cpu switching frequency to manual--> 350

load line calibration-->75%

cpu current limit-->140%

should get it stable from what you said about your chip crashing after an hour or prime
 
Also to save you an hour, use intelburntest over prime95. It will pick up errors in seconds to minutes rather than hours.
