Intel i5 4690k 4.5Ghz OC help

[BiscuitMassacre]

I have a Asus Z97-AR with an Intel Core i5 4690k 4.5Ghz cooled by Hyper Evo 212, but I had to turn off the OC after I installed Asus Ai Suite III. It was originally at 1.25V, but it just kept crashing (after Ai Suite III). It would give these BSOD errors: Whea_uncorrectable_error and System_service_exception. So I turned it up to 1.3V, but then it would just crash without an error (or atleast it was took quick to read). Has anyone got their Z97-A(r) to OC a 4690k to 4.5Ghz? How did you do it? It was fine until I got Ai Suite III, but that may be a coincidence.

I hope you're doing the oc in the bios.

 

I used the bios. I got to 4.7 but that requires a lot more voltage than your 212 evo could handle. Don't go above 1.25v with an evo. I set llc to level 3. If it still bsod's, drop to 4.4 ghz. If that's stable, up to 4.5 with tiny bumps in voltage until stable. Keep your temps under 85°C

 

Your 1.3v crash was probably due to temps.

i used Intel Extreme Tuning Utility to get my 4690K to 4.7Ghz at 1.335V, cooler is a be quiet shadow rock 2 and it never goes above 65c when stress testing

I was using BIOS. I don't think the 1.3V was due to temps. It would never hit 80C. (60-75C is normal load). What do you mean llc?

Llc is a setting, stands for load line calibration. It adds more voltage as the load goes up to counteract vdroop, which is a dip in voltage that happens Asad load goes up. I found setting it to 3 was good for everything up to 4.7, which I used setting 4.

I can't seam to find llc in bios. Is there a different name for it on my board? There shouldn't be much no difference in Z97-A and Z97-AR. Thanks. Should I use adaptive mode for setting the voltage? Thanks

Give me a few minutes and I'll look for it in my bios. I remember having to dig for it.

 

Until you have your overclock rock solid stable, keep it on manual, switch to adaptive after you have it stable and add a small offset to be sure(i used 0.005). Turn on turbo and speed stepping as well.

I the bios advanced mode, click ai tweaker, then digi+ vrm. The first setting is cpu load line calibration, set it to 3 to start and bring it up 1 level at a time until stable. I wouldn't go past 5 though. Llc can easily put too much voltage through your cpu under high loads

[BiscuitMassacre]

right now I have it at these settings:

 

4.5Ghz all cores

Manual Voltage

1.275 overide (1.250 crashed)

 

I set llc to auto

 

Turbo and stepping is enabled.

 

Right now I am running OCCT stress test. current temps is 70C. 

 

This is what I need to do?:

 

Enable adaptive mode with 0.05 override , set llc to 2. If it crashes set it to three and so on. Is there anything I should know?

Don't touch adaptive mode until it is stable. Try llc at 3, run a two hour test for stability. If it passes then you should be fine. If not, bump up llc a level. Before playing with adaptive you want to be sure you're stable.

 

Then set voltage to adaptive, at 1.275v then add an offset of 0.005 and you should be fine.

 

Other than that it should be good to go.

That is what I do not understand.

 

I haven't tested it too much, but 1.290v is stable at 4.4Ghz. 1.3v at 4.5Ghz is too much for my cooler. (OCCT gives off some error about loads or something). How does adaptive mode work? I set it to adaptive to stress test, and then it wouldn't reach 1.22v (according to software), then of course it crashed. It doesn't make any sense. Does it 'adapt' to what was on manual? I left LLC to Auto, so that I could make sure it was stable with Adaptive. Should I jump to LLC3? or should I try other modes? What is the advantage of not leaving it at auto? Thank you

This is mine Maximus 7 Ranger board 4690k and a corsair H105 watercooling. Never had a crash or anything, running this for a year now, max temps maybe 60 on a hot day.

Get your overclock stable with manual voltage and llc not set to auto (So set it to 3, before doing anything else).

 

Keep your voltage on manual. Set it to 1.25v and set your multiplier to 44.

 

Stress test it our for two hours. If it passes, then it is stable. Increase the multiplier to 45.

 

Stress test again, if it fails to make it to two hours, slightly increase the voltage ( try 1.265v) and test again.

 

ONLY AFTER IT PASSES do you switch to adaptive voltage. Add a small offset. And it should be fine. Trying to stabilize an overclock on adaptive voltage is a losing battle.

Gotcha. I will follow your guide.  What exactly does adaptive mode do? Whats the point in stressing manual if Adaptive just chooses its only Voltage?

Adaptive ramps the voltage up and down as needed, up to the limit you set for it. It is essentially a power saving feature, and also helps to Kerri your cpu from degrading.

 

The reason you want to stress in manual is because it can be next to impossible to stabilize an overclock in adaptive mode.

What is the 'limit'? Right now I am running 4.4 at 1.26v. So far so good.

If you're referring to the adaptive mode limit, it is a limit you set, just like manual voltage. If you're referring to the max voltage limit for your cpu, 1.35, but you will have crazy high temps with that voltage.

This is what I did. I had to bump it up to 1.15V later, but it seems you may need higher. Just don't let your temps get above 80C or so.

How can you have 1.15v, what I am just now upping it up to 1.27?

I must have gotten a good chip. Try upping the VCCIN. That's what I had to do.

It changes the total amount of voltage going into the CPU.

Isn't that already of what I am doing? What's the advantage? @incarnate @EarthboundHero

Core voltage is how much is going to the core. VCCIN is how much is going to every component in the CPU. From what I've heard it might not help at all, but it worked for me. There's no harm in trying it, just keep an eye on temps.
