post #211 of 19296
I have some questions regarding 4770K overclocking...

I'm running a 4770K on MSI Z87i, and the maximum Vcore is somehow locked to 1.300v.
Is this just a motherboard restriction ?
or is there something wrong with this cpu ?

I would appreciate the answers much!
Thanks!

That's odd. Try updating your bios?

I did updated the bios, but nothing changed.
The maximum Vcore is still 1.3v.

By locked do you mean it just can't go higher or is it set at 1.300V completely?
Very odd.

On air, max VRIN is 2.0-2.2V. Now, raising VRIN cannot grant higher overclocks. It can only stabilize an OC that you are very close to being stable at. Say for example, you get a BSOD after a few hours of Prime95. You might be able to stabilize it by increasing VRIN by 0.1V. Cache ratio that doesn't have adequate voltage can make you think you need more vcore than you really do. That's why I leave mine on auto, because it doesn't increase performance anyway.

Raising VRIN can also allow you to lower vcore in some cases, but it isn't a guarantee.

I have noticed this behaviour but I have a question... VRIN feeds the FIVR which feeds vCore, vRing, vCCIOD/vCCIOA, and System Agent. Bumping up VRIN has stabilised an overclock in the exact scenario you describe above. Would the same result occur if we bumped all the post-FIVR voltages by +0.01 while trying to keep the VRIN-vCore value as close to 0.4v as possible (as suggested by the ASUS ROG blog post)? In other words, is this a duty cycle and/or ripple issue or is it something else? I ask because it seems like, anecdotally (and I could be totally wrong), high VRIN and/or VRIN-vCORE delta is causing early degradation of Haswell CPUs. Thoughts?

I can't go any higher.

unless there is a setting limiting the max somewhere else in the bios, I am unsure have you contacted MSI about this?

Try using the MSI Intel Extreme Tuning Utility and see if you can go above 1.3v with that.

I wanted to make sure if this is really an abnormal situation before I contact them.
Now it looks like I should!
