Anyone had any luck with XMP working? I can't get my memory to post with XMP on, not really sure what I can push my VCCIO and SA to on these chips.

What is the xmp for your memory? I've had no luck but my xmp is 4266.
I belive it was 8pack that said 1.2v was good for anything above 3200mhz, I'll try find his quote.

Currently using 1.2v for each with 1.4v on the memory at 3866. This is on the asus maximus with the tweak set to 2, without that 3600 was all I could manage.

3333mhz so nothing extreme like yours. I'll have it a go with both at 1.2. Whats the best memory stability test currently?

If we go too many more people hitting 5.2GHz on an AIO with no delid, I can see those who bought a pre-bin sending them back after wasting £150+ on nothing.

Bin not just about clock speed, more about voltage needed to hit 5.1/5.2Ghz.

Reviews look great but not convinced it is worth the ache to switch from a 5.2 7700k.

Considering my 5ghz ocuk rated is running stable at 5.2ghz within the 1.35-1.4 spec i hope the 5.2 rated cpu's can get 5.4

Lets be honest most of us just paid the premium to save waiting two months. I can give up a days wage for that.
Added bonis of a delid as the temps are fantastic.

Currently using AIDA64 which loads everything up together.
And the techpowerup memtest64 works well too, all subjective of course.

Agreed, sadly a lot of people who £150 may be half a weeks wage also ended up paying for what turned out to be a de-lidding service, and nothing more.

It's good that you are getting 5.2 though, and at nice low voltage.

What are the temps like none delidded at 5.0 on 240 aio from what's surfaced so far?

Simon Belmont · 8 Oct 2017 at 11:30

I wonder if I put my 8700k on the bay for £1000 would anyone buy it. lol I probably won't , but wonder if anyone would bite

There's an 8600k there with a starting price of a tenner more than retail

My cpu is the same

Watch my video. Your cooling is maxed out at 1.285V so clocks on average silicon are 4.8-4.9. That's if stress testing none avx 26.6.

Xmp 8Pack sticks posting on all boards I checked even at 4133Mhz. Stability topped out at 4K though on 4 dimm boards.

The simple story is buy 8Pack sticks :-)

Good to hear. I bin very conservative so it's possible with better cooling to go higher. All ocuk 5.1 chips on Kabylake launch could do 5.2.

Mems 3200 io Sa 1.05-1.1
3600 1.1-1.15
4K upto 1.2

^ on almost all my retail chips. Imc strong on these.

To bench I could run 4K c12 1.2 Sa io.

Blueglue · 8 Oct 2017 at 11:56

When i set 1.4v in the bios at 52 x 100 cpu-z shows it peaking at 1.47 but HWmonitor shows it at the correct voltage?! Is that something i need to tweak the LLC for?

8 Pack · 8 Oct 2017 at 12:00

Check cpuz. Which board??

Totally no go with memory on the Aorus 7. The 8pack stuff doesn't do a 2x16gb kit so useless for me.

You said about setting cache to 4.4? I can't seem to find an option for this, my 5ghz appears to be stable at 1.4v atm. temps are all in the 50s during prime.

I think auto was fine on the bios I used. No need for llc. It's easy to test anyway. Go in digipower settings and set level 5 then check load volts, then level 6 and so on.

I think if you do set it the next to top level is correct.
