Hi folks,

I appreciate some of this may have been covered before, however, I have found numerous conflicting comments on some of these settings and would really appreciate some definitive answers from the experts that are part of this community!

My rig contains the following:

4690k, with a 212evo cooler on it, Gigabyte z97-SLI, 16gb of corsair vengeance pro 2400 ram. OC cooler edition GTX 970

I'd just like some clarification on a few points.

As in a post below by someone else, I initially used gigabyte's "Easy tune" facility to produce an overclock of 4.3. However, after doing a little more research I had a look in the bios and realised it had upped the vcore voltage to 1.39v - a figure which looked quite high to me. Stability test was pushing up to 73 degrees on the CPU, which I thought was quite high. Also a few other settings didn't seem quite right and I just wanted some clarification before making any more adjustments.

Firstly - My base clock is at 100.00 and I have set the multipliers on each core to 43.

I also turned down the vcore voltage to 1.209v and the overclock is stable after 3 hours or so with max temps of 69 (this was on core 2) on AIDA64.

Now - the questions I need to ask.

Turbo boost - i've disabled this - is this the correct thing to do?

CPU Vcore offset - should this be set to auto, or just 0.00? What exactly does it do?

Are there any other settings i should consider changing? Any advice would be great.


Next noob question - i've set the memory to "XMP" - i don't really want to tweak ram voltage, so should the base profile for XMP be sufficient?

Many thanks in advance :cool:
 
Turbo boost off is fine if you can see its at the speed you want in windows.

Ofset voltage adds or takes away from the CPUs voltage table. This allows you to tweak voltage but allows the cpu to use less voltage at lower speeds. Or you can just manually set a voltage and it will sit at that 27/7

Just enable xmp and it's set to the rams advertised speed. It will be fine, very little to gain by tweaking ram.
 
Thanks - would leaving the offset to auto be advisable? I'm sure I read somewhere that leaving this, or turbo boost enabled could lead to unexpected additional voltage through the CPU as and when it demands it?
 
Offset cpu voltage can cause the cpu to draw more vcore that usual when you use prime95 or something based on that.

If you don't use that to stress test and use something like realbench instead, then it's a non issue.

I believe it was my post that you're referring to, right?

We have a similar setup, barring the cooler and your extra RAM.

Here's a HWMon shot of mine after 30 minutes of RealBench stress earlier.

*Note:- The VCore is actually being displayed in the VID section, for some reason



4.6GHz on 1.29v with max temps of 64c.

Tbh, from my limited knowledge, the EZ Tune wasn't too far different from the way I have it now. It just didn't set enough voltage, as can be seen in the screenshot I posted in my thread.

I'm a complete overclocking noob, but all I did was turn on XMP, set the 2400MHz profile, set all cores at 46x and upped voltage by 0.01 until it was stable. I didn't really notice whether Turbo Boost was on, actually. It's set to whatever the default is.

I'd say you've got a decent result, considering you're using the EVO 212 and I'm using the H110i GT. I have no clue if I could / should push mine any further.
 
Thanks for the reply Brocky,

I'll post my screenies when I get 5.

Along with the silicon lottery, your cooler is obviously massively more effective than mine. Worth -10 degrees even with more voltage and clock speed. I may have to invest!

Cheers

Do it! It's definitely worth it.

I had an EVO on my last rig. Cracking cooler for the money and was initially going to put one on my new build, but I'm so glad I spent the extra cash and went with the H110i GT. It looks good, performs great (even with the pre-applied thermal paste) and it's even easier to install than the EVO.
 
I got 4.5Ghz Stable at 1.22v and ~68°C stressed with an arctic freezer 13 pro.
don't know if thats of any use to you. I did nothing fancy at all in BIOS (MSI Z97 PC Mate) just adjusted speed and voltage. Thats all.
