Really?! Where did you find this out??? I have a Gigabyte Z170XP-SLI and I was about to get a 7700k. Do you know if this is the case with all Z170 Gigabyte motherboards? If I can't overclock a 7700k, I think getting a 6700k might be a better option.

I think the latest BIOS is just broken. My post comes from personal experience. I cannot push the multiplier of my 7700K up beyond 45 nor can I push memory multiplier up beyond 24. BCLK OC seems to be adjustable, but system fails to POST with any changes.

The new BIOS that supposedly supports Kaby Lake for my board, F20, is completely FUBAR.

Did they change the look of your BIOS in F20? Apparently in the F20 update for the Z170XP-SLI BIOS they changed the UEFI interface.

Is there any word from Gigabyte support if they will fix this? If it's something they will fix in the future then I can bear using the 7700k at stock speeds until they release a BIOS update for it.

Yes. It is much different (and worse!) now.

I contacted them, nothing so far. Very poor customer service.

Gigabyte's initial Broadwell BIOSes for Z97 were broken, too, ticked me off so much that I'm all in for ASRock atm.

Gigabyte has proven to me that I shouldn't buy their boards again. It'll be a while before I consider another Gigabyte motherboard for anything but a budget build.

i've wiped them off my budget list too.. I used to prefer them head and shoulders above ASUS for entry level stuff, but recently i've been utterly unimpressed.. From a H110 board that died for no reason, to an FM2+ board with a vastly under-rated VRM, and slow, clumsy UEFI bios. Both the ASUS equivalents iv'e replaced these with are miles better.

I have the GA-Z170X-UD3, the F20 update completely changed the look for me too.

I have a 6700K at 4.5GHz, and it won't go further, neither before or after the update. This mobo won't let me clock 4 sticks of RAM beyond 2533MHz either. F20 didn't make that worse (or better) either.

Yeah, but does F20 at least let you set to higher values? Mine simply won't. It tells me to go pound sand if I try to push memory or CPU multipliers up any further than stock.

Yeah, the option is still there. Still won't let my sticks run at spec though (2666) :( I'm getting a new DDR4 set and will play a bit with that before I change mobo. Maybe, possibly these two devices just don't like each other, but I'm leaning toward blaming the mobo based on what I've read.

anynews on 7700k oc on asus hero 8 ? order my 7700k today, hope the hero8 is has good for kabylake than skylake

I ended up getting the Asus Maximus IX Code, which is the one slightly up from the Hero.

It will be delivered around 6:30pm today, so I'll probably do the necessary tomorrow.

I've concluded it's the motherboard (asrock z170 pro4s) that is holding my memory back too, which is what pushed me to get a new z270 board.

Interesting, because I own a couple of ASRock Z170 Pro4S ATX boards, and was thinking of upgrading the RAM from 2x4GB DDR4-2400 to 3000 or 3200. What's the max RAM speed that you were able to achieve on this board? It's pretty clearly a budget board, as Newegg currently has it for $89.99, with a $20 MIR, making it $70 AR. Now that's cheap! (For a Z170 board.)

DDR4-2800 is the best stable speed with the 7700k and less for the i3 6100 which was using increased BCLK.

I'm pretty sure it's the board that is holding the memory back - i will know for certain once I swap out with the new board.

Very nice and the apex board looks to be setting all the records thus far.

You should sell me one of these gold samples :cool:

Looks like it was definitely the board (Asrock Pro4s) that was holding my memory back, as setting XMP wouldn't even post.

Booted with XMP on the Code just fine:

Just need to find somewhere selling these now:

http://gskill.com/en/product/f4-4266c19d-16gtza

Lotta posters -- like me -- seem to have a techno-lust addiction issue. We should start a 12-step program for Anandtech.

I have been quite happy for almost 4 months with the TridentZ DDR4-3200 14-14-14 kit. G.SKILL tells me that while SOME 4-slot configurations may work, they can't guarantee the RAM running at its full spec. So if I spring for a 2x16GB kit, I could "move up," or so I speculate. Does it buy more with a 7700K than with a 6700K?

Say,could someone of you who have the cpu be bothered to try some overclocking with two cores disabled to give us some idea of what the i3-7350k might be able to achieve?

yes, all CPUs need to be delidded for 5GHz if you running prime or linx with avx.

good looking board @ RichUK ;)

thanks i ordered the rockit tool and the metal liquid, i have a swiftech h240-x for cooler do you think ill be able to achieve decent temp at 5 ghz ? ill be posting my results when i receive my cpu and tools
