How to have 7700k throttle back during Idle while overclocking

Hi all, just got 7700k. Began basic overclocking, but I noticed once I start overclocking my CPU now stays at the speed I have my cores set to even while Idle, according to CPU-Z

Before OCing, speed would drop when CPU was not needed to be at full speed. I thought this was a nice feature. Any way to still make use of that while overclocking?

Also, for my starting OC settings I have V.core set to 1.165 with all cores at 4.5. Temps float at high 60's low 70's after about 10 mins of prime95. Everything seem right there to you guys?

Lastly, anyone know what the Beta Runner > Real Thread option does in bios?

Never worked on MSI motherboards before so I am alittle unsure what you have changed that makes the CPU run at full speed even at idle.
But the Beta Runner part I belive is an MSI thing that lets people overclock non-k models with easy ( but I could be wrong )

Use HWMonitor for watching volts and temps: http://www.cpuid.com/softwares/hwmonitor.html

As for your temps they are fine for a non delided CPU.
Just stay below 85 celcius.

I can say with certainty that I did not touch anything to change the speed at full idle. The only thing i changed were the core speeds (4.2 to 4.5) and the voltage. I haven't touched anything else, so it must be that overclocking the cores overrides the CPU's setting to do that, which in turn means I must be looking for setting which allows that function to still be used even when OCing.

While on the subject, What does the speed actually do? I would expect the fact that my CPU is running at a high speed would mean my temps would go up, but my temps are normal idle temps despite CPU-Z reading 4500MHz. Maybe CPU-Z doesn't recognize that your MHz are actually temporarily lowered during idle while OCing?

Also I'm using CoreTemp. Is HWMonitor better for any reason?

So, weird. I downloaded HWMonitor and opened it up, its showing MHz floating betwen 800 and 4000. The weird part is, now all of a sudden so is CPU-Z.

Tides goes in, tide goes out.

On the flip side, running just 10 minute stress tests (will test for several hours later) I seem to be basically stable at 4.8 with 1.220 Vcore. That seems really good to me, no? Temps still only mid 70s at the very most (just spikes. Mainly sitting still low 70's)

Hehe could just be that CPU-Z did a hickup :D

4.8 @ 1.220 Vcore is not bad.
Mine is sitting at 5GHz @ 1.312 Vcore.

Keep in mind the 7700k normaly like a delid and liquid metal over the bad thermal paste intel uses.

I never go over 61 degree celcius with prime95 with AVX load running for 1 hour.
Gaming I stay around 42-51 degree celcius.
Without delid I was at 92 degree @ 5GHz.... Not good... shame on intel.

What is AVX load? and yeah I don't really want to delid. I bought this CPU with 4.8 OC in mind. I don't want to go too crazy with it, I'm already super happy with the performance over my 4.2 OC'd 6600k even without OCing at all.

What's your cooler btw? I'm using noctua D14

Now another question. I also would like to have my 2400 ram running at 2400, not 2133. When I simply enable XMP, that brings my temps up by almost 5 degrees just by itself. Is there a way to bring that up without XMP, and when I do, will it effect my CPU OC at all?

And any other settings I should be looking at that I'm not already? Should I be touching ring ratio? All I'm doing here is changing the OC up or down 1GH at a time, and adjusting the Vcore with it. I haven't been touching anything else

AVX = Advanced Vector Extensions
To keep it short it is just an extension from the x86 architecture, and just put a "harder" load on the cpu

As for my cooler I have a custom water cooled loop. So I got one 480mm radiator Hardwarelabs black ice nemesis GTX with an EK supremacy evo waterblock, D5 PWM waterpump, PETG tubing, 8 EK vardar 120ER in push / pull running at 460 - 500 RPM range ( so totaly silent )
So in a way total overkill when it comes to cooling but I want silence even when the system is running at full load.

About your RAM.
You are better off setting that manually in bios. Look up your RAM and find the timings ( also your ram modules have a sticker on them so you can get the info there) and just put in the correct MHz and timings in bios + volts and you are good to go.

XMP bios settings should configure the voltage and timings correctly but sometimes it misses. Best to check the "Memory" tab against the "XMP" profile in the "SPD" tab.
Also make sure your RAM is on the official supported list of your motherboard.


About ring ratio.
Ring ratio is the speed of the interconnects between the cores, cache, memory controllers, and some other parts.
As for overclocking if I remember correct its like this:
-Higher ring clockspeeds decrease stability (especially if cores and RAM are also clocked high).
-Higher clockspeeds improve performance, but not as much as overclocking the cores.
-Having a ring speed higher than the core speed does not improve performance

Basically, a 1:1 core to ring ratio is ideal, but can decrease stability. Having the ring clockspeeds slightly lower than the cores is good enough and should allow you to push the cores farther.

Ultimately, if you're running at 4.3 Ghz core and 4.3 Ghz ring, that's good. If lowering the ring to 3.5 Ghz allows you to push the cores to 4.5, it will perform better, even though the ring is slower.


There is not really any more setting you should pay mutch attention to that would increase the performance that mutch that it would be worth it.
Then it is more down to what you want to play around with just to see of you can. Maybe gain 1-2 fps in games, maybe get a 0.2 sec faster boot time etc.
