First Time Overclocking CPU, Have a Few Questions About Uncore

Dear people of Tom's Hardware, I am going to attempt my first ever CPU overclock using a Gigabyte Z97X-Gaming 5 motherboard. My CPU is an i5-4690k, and my BIOS are up-to-date. I will be getting a Cooler Master Hyper Evo 212 before I attempt to do it, so don't worry about my current setup. (The rest of my computer specifications can be found here - http://textuploader.com/axlfq
). Anyway, my main question is this: how should I go about overclocking Uncore? I know its significance is way less than the core multiplier, but I want to do it anyways.

I am using this guide right here - http://www.overclock.net/t/1411077/haswell-overclocking-guide-with-statistics for all of my knowledge. I have read just about the whole thing and have a lot of notes taken from it. I also notice that it is rather old, and the guy who made it posted it over 3 years ago (not sure if he updated it).

Anyway, my questions about the Uncore frequency (which I'm guessing is calculated the same way as the core multiplier, baseclock x multiplier = X amount of MHz), are these:

1. In the guide I'm following, the OP said to set the Uncore to x33 for Gigabyte motherboards. I have re-read what he has said about it, but just want to check with other people who might've had similar experiences with this setting. Here is where I'm confused: will I still be able to overclock Uncore, because, unless I'm reading this wrong, I can't have it manually set to the stock value otherwise it will overclock automatically. Anyone else know anything about this?

2. Is it necessary to change Uncore voltage (Vring/Cache voltage) if I want to get a higher multiplier? If so, how much does it affect CPU temperature?

    Ahhh, Ring Bus. (No idea why people call it Ucore.)

    What they say is true, It's incredibly difficult to overclock the ringbus with the rest of the CPU.

    I'd recommend leaving the Ringbus ratio to default, and simply overclock the core.


    For your reference, my i5 4690K is currently running at 44x Core ratio with 1.260 static voltage. 39x cache/uncore/ringbus ratio with automagic voltage.

    Thanks for the response. Do you know how much increasing Uncore/Ring Bus affects CPU temperatures?
