Hello my first post here btw smile.gif

I just wanted to point out my silly situation where I was at 4.6 Ghz on 1.3V 3770K hitting 90+ with NH-D14.
My mistake was that i didn't screw the cooler mounting too hard on the mobo due to fear of breaking
some sensitive parts on my shiny new ultra expensive z77x-up7 but kept them rather loose. Once I
screw them down to death my temps went to 61 max on 12h prime95 torture smile.gif

I understand that its really hard on the NB (RUNS MUCH HOTTER) to step up FSB over 100.0MHz. Ivy is set to run 100.0MHz
(Host Clock Override (BCLK): 100.0 MHz
~BCLK stands for Base CLocK.
~Also known as Front Side Bus (FSB).
~Do NOT change this. leave it at 100, otherwise you risk damaging things.)

Thanks for creating this guide, it has helped me out so much! http://www.overclock.net/t/1247413/ivy-bridge-overclocking-guide-with-ln2-guide-at-the-end/940#

I have just OC'd my 3570k to 4.5GHz on my Gigabyte Z77X-UD3H (First time doing an overclock) and i have a Prolimatech Megahalems with 2xCorsair SP120 Quiet Editions strapped to it in push / pull, they are at their lowest speed possible by my fan controller.

I started with a VCore of 1.350 and lowered it bit by bit, and its settled at 1.310, any lower than that and i start getting crashes.





I am happy with them temperatures to be honest, however my CCPLL / CPUPLL is still on auto, would you guys recommend lowering this manually to help lower the temperatures even more? Is there a number someone can suggest to try and aim for?

Although i am happy to leave it on auto if you guys recommend doing so smile.gif


Thanks again for creating this thread!

you can try and lower pll to 1.7 and see if that does anything for your temps. some peep's it helps (I run 1.65 at 4.8 vcore 1.26V) and others it doesn't. Just have to see for yourself.

Hi - i just got up and running and need help to lower my temps - some adjustment tips -

i have the UD5H 3770K - antec 920 cooler - G skill sniper 16 gig - Profile one -

PSU is 750 Corsair TX -

all i changed was the CPU to 4.2 - and disabled the throttle - but it still adjusts the volts up and down - which other settings i need to disable to keep it at a steady volt ?

the ran intel burn test - passed them all - then i put it to 4.4 - i left everything Auto - it runs fine - i passed the test at high settings - but i noticed my temps are maxed out now - two of my cores were hitting 98 and 100 C during some of the testing at the high stress level - it passed and i stopped - not going to try any more till i get the temps lower


is there anything i can do in the bios to lower the temps - ?

i have put Cougar HP fans on the cooler - instead of original - i hear they are very loud - at idle it starts at about 31 C - slowly goes and stays at 34C - during the stress testing - it shows 38C

this is the Chill software showing the liquid temps - i am thinking maybe i should try different fans also ? my room is on the warm side -

i am looking to get the Corsair fans HP models - ? i think i read some people used them and work good -

i am looking to get a good 4.5 OC stable for 24/7 use - if i can get 4.7 OC - i take it - as long as temps are in check - i also just got the protection plan just to be safe smile.gif


thanks

one thing might work, dont use Auto for vcore, most of the time it will give more then needed,
lower vcore=lower temps
for 4.4ghz, try set 1.25V vcore to start with, its prolly to much, but after testing you can lower it some more,
lowering LLC can sometimes help with temps, amd make your oc more stable,
1.8V is default, some go down to 1.5V, 1.65-1.75 is what i used most of the time,
dont go over 90C with stress testing, or at least stay close to it smile.gif

did you try reseat your cooler, its a good one, but your temps seem a bit high to me at 4.4ghz,
could be just the chip, i couldnt run ibt at 4.5ghz without hitting 105C within seconds..

Ok i went in manually and i got 4.5 stable 7 hours prime -

now running IBT 4.7 - at Max settings for IBT - its on Round 8 of 10 - it feels good and i expect it pass

i have my Vcore at 1.325 for now - didnt want to starve it - if all goes well - i try 4.8 -

here are the pics - anyone can give me more suggestions - would be great -

this place has helped me alot - i did read each single page from page 1 - during the past month - my first attempt went very bad - with putting my system together - it was a A10 - FM2 board -

now i went with 3770k UD5H - G skill 16 gig kit - antec 920 seems better now - first one didnt pump full speed - this one is better - but my room is warm so hard to say

my temps are much better now at 4.7 then it was at 4.4 with everything on Auto

here are the pics - almost done with 4.7 - Round 9 of 10 smile.gif

i am hitting about 95 C with IBT Max stress settings - its almost done - and i tighten it down pretty good this time - it dosnt screw down any more -

i am running the cougar Vortex HP fans - noise isnt bad on full - but i think it could be better - changing them out for the Coolermaster Xtraflow - and then will try for 4.8

i think the new Fans will bring it down a bit in temps overall - well will see -

OK done with 4.7 -

what do you think with this OC
post #950 of 1508
Very nice results expresso thumb.gif Are you using any LLC in your bios? I'm looking around for the Corsair SP 120 fans as I have heard reports that the Static pressure is good for radiators and like you I have the 920.
