I am having all kinds of issues with this combination of chip and board...particularly when it comes to overclock.

1) All of my attempts at overclocking have failed....very unstable P3D.  I have reverted back to stock....which I am ok with.

2) But even at stock settings, by cpu clock speed on core 1 (or zero, not sure), I cannot get the chip to overclock to 4.7 as it is supposed to.  It is stuck at 4.3.

Just wondering if you have this combination could you share your settings?  Thanks.

At stock that CPU should go to 4.7 all by itself. I'd look at getting it setup correctly first before checking into any overclocking. There should be plenty of good online tutorials.

maybe have a look at this thread. some boards disable the c-states in other cores by default, which keeps the cpu from turboing itself to 4.7. to solve it is just a setting to flip in the bios. not sure if this applies specifically to your situation but worth a look perhaps. http://www.overclock.net/forum/5-intel-cpus/1645297-8700k-doesn-t-exceeds-4-3-ghz-stock-3.html

Thanks I will give this a try. 

I not use apps like throttle stop, you have all settings in bios.

I run my 8700k at 5.4ghz all cores synced , men speed 4266mhz c17

Cooling aio x62 vcore 1.39v

All 8700k i tested have managed 4.9ghz all cores with less then 1.37v HT on , 75% 5.0ghz

Must be someting with your bios settings,the mobo you have shall be fine.

I run Asus mobos but Most be someone here that can share a basic setup för the gigabyte bord.

Here is some Reading

This is about an Aorus Gaming 7 mobo + 8700 . Maybe you can find ideas

I would also check your BIOS is up to date, my system ASUS board already required a BIOS update after I built it last year, and I've just installed another update a few weeks ago and there is another in the pipeline, partly due to the security issues that came to light some months ago, my latest update included better support for MV2 and Samsung SSD drives.

This!!

I had several problems with my mobo (including BSOD's) making OC's in my 8700k before updating to the last firmware , also check if your chipset is up to date.

PS: i have a different mobo
