Setting for uncore

[Sulli989]

I'm overclocking my G3258 and stuck at 3.8GHz. I've been leaving the uncore at auto. Should I leave it on auto or set it to a specific ratio.

Yes, leave it at auto until you max out the core.

3.8 is low for a g3258. What board are you on? Cooling? vcore?

Gigabyte Z97X-Gaming 5, and a Corsair H100. It says right there in his system specs...

With that board and cooling, OP, you should hit 4.5 with relative ease.

What changes have you made in bios? When I had that chip for a hot minute, 1.3v out me at 4.5GHz w no other bios changes (other than setting XMP profile).

I have tried upping the voltage. I use intel burn test to check for stability. Anything higher and it won't pass. I've disabled speed step and the other power saving features that may cause a problems. Thinking maybe my chip isn't a good overclocker. Heard similar stories elsewhere. What is the max safe voltage for these chips? I bumped the voltage conciderably.

Just touch the user name. The mobile version brings up a user box. On there is profile page. Then you have tabs to see everything, including system specs.

Again, what are your current OC changes in bios? You can go up to 1.35-1.4v so long as temps stay in check (and they should with an H100i). I've only OC'd 1 G3258, but when I did, all I changed was voltage to 1.3 and multi to 45. Rock stable there and it was in line with the vast majority of others' results. You should de able to get to 4.2-4.3 easily, even with a dog chip.

I disabled the power saving features and raised the multi. When it failed the stability test at 4GHz I raised the voltage. No matter how much voltage I put it would not pass. Thats why I have posted in case I have overlooked something. Such as the uncore ratio or is there another voltage I need to look at( vrin?). I have overclocked chips in the past so I have a base knowledge of how it's done. I've changed no other settings.

During your stress tests, does CPU-z report the expect/increased voltage correctly?

What stress test are you using?

What did you raise the voltage to? A number. It's possible you think you're raising it, but you've actually set it below stock.

Is your RAM also overclocked?

I would reset bios to defaults and run the stress test at stock, just to get a baseline.

 

[Sulli989]

I increased voltage to 1.375. CPU-Z reported it. Ram is not overclocked. Already ran a stock speed stress test and it was stable. I'm using intel burn test.

 

[ninjacore]

That's certainly surprising. Definitely a well-below average chip. Sorry about your silicon lottery luck

If you bought it locally, you could exchange it?

Sounds like you've done all you can. I have no further suggestions. As to your OP question, increasing uncore speeds won't stabilize your core OC.

Thanks for your help. You confirmed what I thought. A little wishful thinking on my part.
