4670K voltage question?

post #1 of 6
Thread Starter 
I've just started to play around with my 4670K (on Asus Z87-A) running a Cooler Master Hyper 212 Plus with a Scythe Slip Stream 140mm.
I've set the "Sync All Cores" to 42 and put the "CPU Core Voltage" at 1.069 (manual)
I've tested it by running Prime95 and it seems stable enough (sub 80C).

Before trying to get either higher clocks or lower volts I was looking at getting the voltage to not be constant.
Obviously having the voltage set to manual it stays at 1.069 even when the multi drops to 8.
Leaving the voltage on auto results in having it ramp to 1.28 and exceeding 90C (very quickly).
I've tried setting Adaptive mode (to 1.069), but this seems to go past the maximum that I set.
I've read that it is either supposed to do that, or a known issue, I'm not sure. Either way, not unexpected.

I'm looking to get a 24/7 overclock that retains the same characteristics of the stock settings: underclock & undervolt at idle.
Is Adaptive mode something I should be looking at?

You should trying setting your actual desired VCore in adaptive voltage (just like you mentioned), while keeping LLC at its max to eliminate any vDroop in terms of spikes.

If it still goes over your set volts, then Haswell surely needs a little more VCore when it pleases (however, not necessarily in normal apps).

You can read all about how to overclock your Z87 system here:

If you need further assistance, start your own thread in this same forum. Good Luck!

Taking this into consideration I've done some further testing and it seems that it is only during stress testing that the volts keep peeking past the adaptive point. In order to get a more real world orientated load I ran Handbrake and I'm just seeing voltages jumping up here and there, only for a moment. Temps are well in order and everything looks stable enough.

I'll switch back to constant voltage to push the multi up some more. Once I get a suitable overclock I'll switch back to adaptive for stability and temp testing. That should leave me with the kind of overclock I was looking for.

Thanks for your advice smile.gif
