Intel i7-8700k Asrock Z370 Taichi cpu frequency and voltage

[clubman]

Hi. I have Intel i7-8700k. Every setting in BIOS is by default, just as the settings the motherboard(mobo) came with. Are these numbers ok when on idle? I have noticed that it constantly hits 4444mhz exactly(not more,barely less) while just installing a game. I'm using A-Tuning which is software by Asrock and supplied with the mobo. It measures everything just like Aida64, so I can trust this software. CPU-Z was showing lower numbers, but from the posts I've read, CPU-z is not to be trusted. Also have this BCLK Frequency 101 or 100mhz, which I know is used to oc non-k, non-oc cpus. Should I check in BIOS and disable it if it's enabled? I think it is on Auto, which in most cases means it's enabled. Also I'm "affraid" of touching anything for now in BIOS, because Im new to it. I have the latest firmware 1.20 for this mobo. So is my cpu running by default(normal settings-3.7ghz up to 4.3ghz on all cores when in turbo boost), or is my mobo Bios sort of overclocking it by default and have to disable something-beacuse 4444 is more than the stated 4.3 and I assume i have a little OC, probably the BCLK +101mhz. My idea is to have every setting running normal for the moment I learn how to overclock my cpu and RAM by myself, because I've understood that overclocking with the supplied with BIOS automated methods is not welcomed - like xmp, ot multi core enhancement. Please,don't tell me I shoud have bought non-k CPU if not overclocking-I will, but not for now. I have attached a link to the picture. Just click ot the http, I don't know why it's showing only this part from the whole link. Thanks!

FYI, use some paragraphs and spaces after your sentences. This is a very hard to read post and you may push people away from helping you.

I would not use A-Tuning or any other software for overclocking. If you want to overclock, do it from the bios.

To make it easy, set the BCLK to 100, but do it from the bios. The BCLK is not just for overclocking non "k" chips, it is used for overclocking the system. But you should not mess with it if you don't know what your are doing because you will also be overclocking your RAM at the same time as your CPU. Plus, the math gets fuzzy with 101 instead of 100.

Your multiplier is set to 44. Your BCLK is set to 101. 101 times 44 = 4444. This is why you are seeing 4444mhz on your clock frequency. Why your multiplier is set to 44 is probably because of one of two reasons. 1, you inadvertently set it there. Or two, it is reading the boost at that point in time. The 8700k boost more on fewer cores. So if you only 1 core is being used, you would get 4.7ghz stock, or 4700mhz. So in that situation, if you were using 4 cores, the CPU clockspeed would be 4.4ghz. So your clockspeed will change, depending on how many cores are used.

If I were you, I would get rid of the A-Tuning software and download Intel XTU. Do not use XTU to OC your chip, use it to check your temps and clockspeeds. It is designed by Intel to be used on Intel CPUs. Intel knows a lot more about their CPUs than Asrock does.

Thanks for the correction. I will check Intel XTU.

Can you recommend me a link for overclocking my CPU and RAM that you think is safe and good? By safe, I mean the method, used for overclocking, is right. I know that in each case it depends of the silicon lottery. But I don't want to go sky high in numbers. About 4.8ghz on all cores would be fine. I hope the CPU will allow this frequency on a relevant normal voltage up to 1.35v and temp. I am using 16 gb ddr4 Corsair Lpx 3000mhz. I'm using air cooler by Noctua NH-D15. The case is Thermaltake View 71. Cheers.

Pretty much everything in this guide for Skylake should still be valid for Coffee Lake:

Manual overclocking of your RAM isn't really necessary though, just enable the XMP profile and it should be running at 3000 MHz no problem.

Here is a video from jayztwocents. He explains things pretty easy. You may not find a lot of info just yet on overclocking the 8700k because it is new. But there is not a big difference between the 6700/7700/8700.

It's Paul's Hardware. Did you mean the same video?

Haha! Oops. I clicked the wrong link. But I am sure it is good. I just like jayztwocents because he explains it pretty well.

Here is on from jay.

Here is another from jay that talks about CPU safety and overclocking. It is good to watch so you can learn a little bit about it.
