Overclocking has changed - a little guidance needed.

It's been... a while, 7 years since my last MB and CPU change. Back then things were simple. The BIOS on my new motherboard - Gigabyte Z97X-SLI - is so different, things have moved on somewhat in BIOS software eh!

Let's just assume I'm a noob (as I feel like it tbh), so I need an idiots guide for overclocking my i5-4690k. I also purchased 8GB of 2400mhz RAM (TeamGroup Vulcan Red), so want to get the best out of these too.

Any decent guides out there for this combo?
Also what monitoring and testing software should I be downloading to check for a stable overclock?

Any help greatly appreciated! :)
 
What sort of speed were you after?

If its a low'ish 4Ghz then just try setting the four Turbo boost ratios to what you want (such as 40X) and see if it boots up and is stable.
 
Not sure yet Stulid, still haven't replaced the stock cooler. What sort of speeds are people managing on air? Is 4.5 achievable? I'm happy to test 4Ghz out to begin with if it's just a single multiplier change and see how that goes. Then once I receive the brackets from Noctua, I can push for higher.

From what I have read it seems that RAM is no longer tied to the FSB (is that term even relevant any more?) like it used to be and the overclock on the RAM is independent. Is that right, or am I misinterpreting things?

The RAM I purchased is 2400Mhz rated and is currently running at 1600... so I'd like to push that up a bit.
 
4.5Ghz should be easy enough with a £20+ cooler and a willing CPU.

4.0Ghz should be as simple as adjusting the turbo ratios all to 40X and maybe setting vcore loadline calibration to Turbo/extreme, then whenever under load CPU-Z should show a solid 4Ghz no matter how many cores are being used.

The FSB is now the BCLK, you dont need to alter this from its 100MHz setting.

To get the RAM up and running, go into the advanced memory section and load the XMP profile, save+exit.

Then post up a pic of CPU-Z SPD and Memory tab to confirm its all set up correctly.
 
OK, thanks, I'll give it a shot this weekend when I have some time. I'll stick with 4Ghz for the time being too.
 
Followed your advice and loaded the XMP profile for the memory so that is now running at 2400, confirmed in CPU-Z.

I upped the the multiplier for the CPU to 40 so that is now running at 4Ghz. Haven't touched the 'vcore loadline calibration' that you mentioned though.

Ran a quick benchmark in Asus Realbench that was suggested my MrMD. idle temps are arounf 30 and max temps during the bench reached 73.
 
It's still mainly all about vcore and finding the cliff wall where voltage requirement for stability is much more volts and stay just on the turning point.

For example on my haswell pentium k 4.5 ghz requires 1.28 voltage but 4.6 and above needs 1.375 or more

I'd just play with cpu vcore don't be surprised if 4.6-4.8 ghz may require 1.35-1.40 voltage

An important thing to do is stress/game/stabilty test with power saving features all off and using manual voltage

Also you might have to use adaptive voltage when you find a voltage and clock you are happy with this is done by changing cpuvcore from auto or your manual number to normal and underneath it adding + mv so if your default voltage is say 1.1 volts adding 100mv =1.2 volts and so on

I say this as your voltages might not go down with power saving states on when the cpu multiplier drops in windows it doesn't on my gigabyte Z97P-D3 without using adaptive voltage

Just remember not to stress test when using adaptive voltage set it back to manual

set input voltage VCCIN to 2.0

Don't bother with uncore overclocking until later leave at 35x (not auto) and uncore voltage on auto

overclocking the uncore doesn't seem to add much in performance from what i have read
