Cant or wont go over 4.5ghz ?

Dillinja · 17 Jun 2013 at 21:33

I have a 3770k on a sabertooth z77 16 gb 1600mhz ram and ive got to that point on overclocking 4.5 @ 1.220v on manual with other settings of course but il keep it brief to start with

...and in aida after 2hr max temp is 70 and it runs in aida mid to high 60 under full load peeking at 70...

the problem is even if I set 4.7 and take the plunge I was going for 1.270v @ 4.7 with LLc and Phase power on extreme but when I boot into windows its still @ 4.5 under full load of course...and if I use turbo v evo leaving everything the same because it keeps voltage changes but not the frequency

....any help would be a great....ermmm....well help !

thanks guys

Ha no matter what I set in the bios it never goes above 4.5 ? anyone any ideas sorry im such a noob I don't even know if thas a noob question..

What you have is a stuck multi.
You will find going up or down in the BIOS makes no difference.

It was a common problem with ASUS Z77 boards which you have i believe.
You can get round it by resetting the CMOS.

Best way though is to update your BIOS, the latest versions have fixed the issue.

ok great thanks for the info...im on 1805 do most run the latest version then ?, I tend to not update bios unless I run into a problem which after I posted this thread using the software the multi " unlocked " its self because things are fine now.. 4.8 @ 1.310 peek temp mid 80's so im not really cool with those sort of temps on 24/7 oc but maybe with some work knocking things back till I know lowest limit temps may improve abit...but still have questions

@ 4.8 and 1.310v no load, under full load vcore says 1.320 but VID says 1.2209 so I understand it 1.320 - 1.2209 = 0.0991 round that up 100, does this mean I need a offset of around 0.0100 when I go to a offset voltage? or am I way ff the mark and it doesn't mean that at all ?

be carefull how much offset you use as each llc level will add a portion of voltage ontop of what offset adds,both those get added to the cpu's default vid(stock voltage)

best to try with small amounts of offset and a high/very high llc

maybe +0.050v and keep adding two clicks at a time until stable,stress the cpu and look in cpu-z to see what load cpu voltages are

stay below 1.4v cpu v and 80-85c if you can

by you above voltages you would need +0.100v =1.3209v but I would start low and work your way up just to be safe

nice 1 wazza !...thanks il give it a whirl tonight...sometimes I feel Im jus chasing setting all the time and getting no-where

.. I think not really knowing what im doing helps that situation...id love a walkthrough with a OC with someone who knows what they are doing....its good for 4.8 with nice ish temps (85max) but im not sure if how I got there was good...?? like u said wazza high llc with small offset...but until today ive only ever been messing with manual vcore...im lost and need help...

cheers..
