Moving a manual voltage to an offset - Haswell

Hey guys,

I'm having problems moving my manual voltage OC to an offset voltage.

On a manual voltage I need 1.35v for 4.8Ghz, but if I try to move to the same voltage on an offset I get a crash also straight away after loading.

It seems to me that I'm getting voltage dips when using offset.

My Mobo is perhaps not the best, I don't seem to have control over LLC, unless this has changed name for Haswell?

Any ideas?
 
try slightly mre voltage for offset,all you have to do on haswell is set all power states from auto to enabled and it will throttle using a fixed cpu v

so c7/c1/c3/c6 eist,intel speedstep set to enabled and set to balanced power profile in windows
 
Why change it to offset though? I have the same board as you with the latest bios, the cpu voltage is set to manual but still drops to 0.736v at idle. All power states are enabled along with eist, speedstep and blanced option in windows.

LLC is under the Digi+ VRM settings.
 
You can also use adaptive voltage. You just put the voltage you want into the max turbo voltage field, then it will use the default voltage for all steps apart from when it hits max clocks where it will use whatever you want it too.

That's what I use on my 4770k at 4.5Ghz and it works a treat. Slightly more efficient as offset will apply the offset to all voltage steps.
 
I have just flashed my board to the new bios that's just come out. Now with the voltage on manual my voltage no longer drops at idle. Fair enough i thought, so i change to offset. Stock is 1.184v and i need 1.265v for 4.5Ghz which equals a offset of 0.081v. Enter this as the offset, save and reboot. Waited at desktop but now only drops to 0.800v at idle instead of 0.736v. Ran Linx to see what it was doing under load and it's just as well i did!! It breifly goes to 1.280v before heading to 1.385v!! How the hell is that even possible? Going to go back to the older bios i think.
 
Flashed back to the bios i was on before and the voltage no longer drops at idle with a manual setting. Why couldn't i leave things alone? Now i have to faff around trying to get the voltage to drop again.
 
it should drop with all bios's

maybe a cmos clear and loading optimised defaults after you've flashed might help
