So yesterday i under volted the chip to 1,75

It still runs turbo on all four cores.

Now i punt prime95 blend on before i went to work and left teamviewer on.

Unfortunately i can't connect which means it probably BSOD'D

I have a question.

Should i set the ring voltage, vrin, uncore voltage to manual ? I'm not sure if the "auto" mode from the mobo can be trusted.

As soon as i get home i'm gonna try 1,85v Vcore and stress that.

If i get this thing stable...

And i want to overclock..

Can i increase the multiplier of the Turbo? instead of increasing the Base clock, Uncore multiplier, BCLK

1.75 is NOT an undervolt, it's an overvolt. Any auto voltage should be turned off, there might also be options like "adaptive" which overvolt too.

I'd suggest only bothering with the vcore, not the other voltages. In fact, I'd say just turn off turbo entirely and set it to run at 4.6ghz maximum on all cores at all times, at a typical voltage for that clock. You could use power saving features that drop the clock under light loads. You can search for 4790k overclock voltages. I would also turn off spread spectrum.

Since every motherboard is different, you're going to have to figure out what means what and what seem appropriate in your motherboard bios. Some even have utilities that allow you to make bios changes directly in windows.

I meant 1.175 volt

There is no adaptive voltage settings in the z97 gigabyte.

The options are auto or normal or i put it in myself.

As your temps go, vcore and core multiplier will determine your temps. If you want to mess with the other settings you can, or just just try 4.6 and find a stable vcore, and leave everything else on auto. You can tweak everything else after you find the stable core settings if you feel like learning some more.

I heard that leaving everything on Auto will trigger some kind of adaptive mode. and that is dangerous for your cpu.

Also i have a question that has been bothering me all day now.


Why do i overclock my base core multiplier? Why not my turbo?

What is the difference between running 47 Base clock multiplier and Turbo OFF Or running Tubo at 47 mutliplier?

With your windows power settings set up correctly, there really is no reason to run turbo as windows throttles your cpu down to 800MHz when not under load. If you want to turbo up to 46, then you need to find your stable voltages at 40 and 46, then turn on turbo and figure out the settings in your bios to get your mobo to boost to those voltages at the 46 mult. It's much easier to just make your core 46 and disable turbo all together. Hope that answers your question.

Yes it does !

I'm going to try this as soon as i get home from work (in 1 hour)

I left Prim95 on with my undervoltage 1.175 + Teamviewer so i could check up on it.

But when i got at the office i could not connect (aka it crashed hard)

So when i get home i'm gonna try ur method starting at 4.5 ghz at 1.2V

Just the vcore btw ? and multiplier ?

What about ALL these things ?


"Example of 4.5GHz OC with XMP and drop in CPU voltage and multiplier at idle (If you don?t see a setting below then assume it is ?Auto?):
Frequency:
CPU Clock Ratio: 45x
XMP: Enable
Uncore Ratio: 40x or 43x
C1E: Disable
C6/C7: Disable
CPU Thermal Monitor: Disable
C3: Enable
EIST: Disable
Voltage:
CPU VRIN Loadline Calibration: Extreme
CPU Phase Control: Extreme Performance
VRIN Override: 2.2v
VCore: 1.275v
Ring Voltage: 1.1v"


or this


"An Easy 4.4/4.5/4.6GHz Template:
Here are the settings I used; you can use them as a template for your settings:
Profile #1 Basic Profile:
CPU VRIN Override LLC: Set to Extreme (this is to make sure VIN doesn’t droop)
CPU VRIN Override Voltage: 1.7-2.0v (reduce if temperatures too high is causing instability, increase if temperatures are fine and you are unstable)
VCore: 1.24-1.34v
Ring Voltage: 1.15 or 1.2v
CPU Multiplier: 44x-46x
BCLK: Auto
Turbo: Auto
C1E, C3, C6/C7, and EIST: All Disabled (

You can set your llc and phase controll to extreme. I've read that helps.

Set your uncore manually to 40x. I've read that leaving it on auto can mess with your OC. I set VRING manually to 1.050v, but setting it to 1.150v may be a better starting point.

Start with your VRIN at 1.900v and your VCORE at 1.200v (maintain a 0.5v difference between the two for now)

Leave your c-states and eist on auto. Keep xmk on profile 1. Only change these if you are looking for your CPUs maximum limits.

Now set your core multiplayer to 46 and see if it passes 30 min stressing. If it passes, lower your VCORE by 0.010v and see if it passes. If it fails increase by 0.010v. Keep your temps under 85C

You're using the stock cooler still, right?
