Need Advice with 4670K OC

dave_trimble · May 20, 2014

I have a 4.4GHz OC on my 4670K (at 1.140v) that has been stable through stress testing and gaming for a couple of weeks now. One slight problem though - as far as I can tell, the CPU is running at 4.4 GHz constantly. By my understanding, this means that speed step is disabled. But I can't turn on speed step without also enabling turbo boost, which I've been lead to believe should be disabled for Oc'ing. Here are screenshots of the OC section of my BIOS:

So the question is, is it a problem to have it running at 4.4 GHz all the time? Temps certainly aren't an issue, but I don't want to risk unduly shortening the life of my CPU. I would appreciate any help/advice you guys can give me.

System Specs:

CPU: i5 4670K @ 4.4GHz, 1.140v
MB: MSI Z87 G45 Gaming
Mem: Gskill Trident 16GB 2400 CL10
GPU: Dual Sapphire R9 290 Tri-X OC in Crossfire
SSD: Samsung 840 Pro 256GB SSD (OS)
Crucial M500 960GB SSD (Storage)

You have the wrong ratio adjusted. Turn that back to default and put ring ratio to something between 34 and 40. (Lower allows better core clocks.) Now, go into CPU features and change the multi there.
Source: I own a g41.
(Also, that's a good chip. Mine does 4.4 with 1.3v.)

Here's a screenshot of my CPU Features Menu. I'm not seeing any options in there for adjusting the ratio.

I agree. If he's hitting 4.4 stable in 1.14, that's a good one. It may have a lot more potential available with good cooling.

dave_trimble :

Hm. What you did have adjusted was the minimum clock speed, so that obviously didn't work. Let me take a quick dive into my UEFI really quick.

I'm using a Thermalright True Spirit 120 cooler. It's not the most robust cooling solution out there, but I picked it for it's excellent cooling performance while being silent. Also, I'm sure I could do better on my OC, but not sure if the benefit would be worth the increased heat/hassle

icraft :

I think what you're missing is that I have the CPU Ratio Mode set to fixed, which may be the answer to my own question. The problem is, once I change that setting back to it's default, it turns on Turbo Boost, and I can't seem to disable it. SpeedStep also comes on, and by my understanding that's what allows the CPU frequency to drop during idle.

dave_trimble :

You got it perfectly. You will need to change it back to default and then those will appear. They limit the turbo boost to the multi you set, you will not need to worry about them.

Also, if you don't mind will you try to set your vcore over 1.3? You don't need to apply it, just see if it will show values over 1.3v. Mine will not.

Thanks, I was under the impression from some other places I've been reading that you don't want turbo boost on when OC'ing. But if what you're telling me is correct, then it doesn't actually matter at all.

I'll check on the voltage setting and get back to you.

dave_trimble · May 20, 2014

icraft :

OK, this is odd. I made the changes, and right now my CPU still reads at 4.4. With only a browser open, I would think it would drop to a lower frequency.

Re/the voltage question you asked - yes, I can go above 1.3. As soon as I go above it, the numbers turn red, but it'll still let me do it.

Turbo Boost and EIST are both fine while OC'ing. Enabling them will allow you to see the individual core multis in CPU Features Menu.

Dave - Be sure that you have selected the "Balanced" option in Windows Advanced Power Options, not "High Performance, IF you want your CPU to throttle back during low load.

dave_trimble :

I had the same problem and Y0GI has the solution. High-power also works if you tell it to be able to lower the CPU usage, but it isn't necessary.

Re voltage again. That is odd. Maybe it is the G41's built in safety against idiots. (It is budget after all.) I'll find that out.

dave_trimble · May 20, 2014

icraft :

How are you increasing the voltage? Using the +/- buttons? Or just typing in a number? If one doesn't work, try the other.

Thanks, Yogi. I didn't even think of the Windows power saving settings (obviously). That did it.

dave_trimble :

+/-, I'll try numbers.

dave_trimble :

Glad you got it going! Enjoy the luck the silicon deity's have given you!

I tested typing the numbers and it just reduces them by a couple points. Guess I'll ask MSI.
