Just as input, i assembled my 8700K today on Asus Hero.
8700K @ 5.0ghz 4.6 uncore, 0 AVX. 1.36v, LLC 5.
Im in brazil (its night here, around 28c), and i have 2 1080s inside case with h110i with 1200rpm.
Ran OCCT and realbench. My max temps were 68c. Im pretty shocked. This time i delided and resealed back with RVT. For comparision, i delided my 7700K and used superglue on corners, temps were around 70 on realbench. I dunno if its related to better vrms or better chip, but it was so easy it seen this chip can probably run 5.1 or 5.0 on even less voltage.
Coffee lake is really impressive, even more after you delid it.
Hi, i dont think your temps are too bad, considering you dont delided.Originally Posted by 5WA7
Hey everyone,
Not delidded
Temps however seem pretty high for that voltage in stress tests… they seem to be higher than what I've seen from other people that haven't delidded
P95 26.6 small ffts peak around 78C (15min run, short run just to check temps)
X264 overnight peaked at 75C, and realbench for 15mins at 75C as well.
Gaming wise, AC:Origins peaked around 73C
Could it be the CPU cooler not mounted properly? I used kryonaut evenly spread and have an R1 universal. When I installed it it seemed to have pretty good contact.
Or could it be the TIM between the die/IHS?

Why dont you go 802? I just installed it today, Asus always force you to update to their latest, i was on 203. 802 is doing well, no problems so far here, only issue i wasnt aware Asus bios by default limit current so i was like an idiot looking why my frequencies were falling all over .Originally Posted by gammagoat
Anybody know where I can get bios 0505?
Tried looking for it HWbot and the official Asus page.
Maybe if some one has a copy they could upload to Drive?

Now on Asus Hero z370 i found out how high the own mobo set it, dialed it down a bit and P95 is stable.
One thing to remember about prime is that is badly intensive on memory as its on cpu. Increasing ram reliability might give you prime stable. If you keep raising your vcore you eventually will not even be able to stablilze it. For me, realbench is good enough. I know a lot of people consider p95 the standard test, but, personally, if you dont need absolutely insane stabilitty for some math or science calculation, and it is stable on realbench, especially if you are gaming, then stop worring.
Just a side note about Prime95 tests. When i was doing on 4790K and specially on sky/kaby on Asrock, i was using a very narrow VCCIO and VCCSA, 1.2 - 1.6. I was using even lower before, below 1.1. Thing is i installed 3400 gskill and thing started to crash along all apps, so i started to ramp it. I couldnt even have occt stable.Originally Posted by Falkentyne
Keep it as is. The lower the voltage you can go GAME STABLE the better. Do NOT try to degrade your CPU to make prime stable if your games don't crash. It's just not worth it except to feed OCD.
If you were below 5 ghz, then yes you should have at least NON AVX NON FMA3 stability in prime, as this would assure you would not crash in anything. The acid test is 1344K fft's in place (Non AVX). Just don't try to do that test with AVX at such a high vcore and multiplier.

Probably wont matter as my chip wants 1.375 with LLC 6 for a stable 4.9.
0802 is what I currently have installed, hearing that 0505 may be the more stable of the two. So I want to have it on hand.Originally Posted by postem

Maybe i am overreacting but that is too much for 4.9 considering i am at 4.8GHz 1.20V, i don't understand why you people use LLC, i use LLC just for my X58 Machines, i have never used it for any of my other Machines.Originally Posted by gammagoat

Be lucky you got a good chip but dont think so high and mighty of yourself that everyone else is using "too much voltage." Maybe their chip is simply not as good. Silicon lottery exists for a reason.

Set LLC to turbo
Core at 5.1
Uncore at 40
cpu voltage at 1.34
Ram on xmp (it auto detected 3200 14-14-14-34 exactly as the spec of the kit I bought)
Also, which on is to be taken as the right info, cpu-z or HWinfo64 ?

Ignore VID, scroll down to the ITE sensors for Vcore reading - most accurate is the 8792E. Also you should be able to raise the uncore a good 400-500 MHz, if not more, for a small gain in performance.Originally Posted by Laethageal

Did you get your board??
With the Gigabyte Gaming 5 and average 8700k same lot as you, I am stable at 4.7ghz so far all cores stress tested passed. Using 1.25 manual voltage set in bios with LLC on Turbo mode which is a higher level and still get some weird vdroop issues in between programs running and using 50-100 percent full load. Using 44 for uncore ratio and xmp setting profile for corsair RGB 2x8gb sticks at 16-18-18 3200 speeds. Disabled a lot of stuff in bios to get stable. Using a gigabyte cheap wind force 1080.
Played an hour of Battlefield 1 at 1080p ultra dx11 with 200fps cap that I was hitting on servers in USA with a ping of 18-20. Used fps counter in game and system usage overlay. My minims were 4.5-5ms for CPU and gpu on smooth levels and my max were 8-12ms. Smoothest 64 level map gameplay I ever had using cheap 1080p 60hz Dell monitor. Also used gaming keyboard and mouse. With all of this temps on CPU we're 70-73c using an Enermax ETS T40 Fit cheap copper 4 pipes CPU cooler with 120mm fan up to 1900 rpm and two front 1 rear 120mm case fans at 600rpm. Gpu got up to 68-70c.
Saved stable profile for these settings and next is up to 5ghz around 1.36 - 1.4 volts and will use my Noctua NH U14S and different pc case that it fits in which should handle temps for 5ghz then I will call it complete for this project which will leave my 7700k syst m collecting dust until I put it up for sale.

Batch# L733c404
Any body with this batch and have good results ?
I don thave my aus miximis rog hero x board for 2 more days .
Its killing me to know . ...
If i can get 5 ghz all.cores no avx offset
@1.39v or under im saticfied
If i can get 5 ghz all.cores @ 1.35v ill be happy
Anything more then that is icing on the cake .
Anybody ???
You could have damaged your ram, I suggest getting memtest uefi 7.2 or newer boot off USB and run the auto defaults it starts up with. You could have also damaged or burnt out the memory controller in processor.
I had similar issues with a 7700k, it's a bad chip for silicon and after trying to get it overclock high and stable, something got messed up because after putting it back to stock settings with ram and no xmp, it kept getting errors during test 6 in memtest. Although same ddr4 ram in two other systems tested fine with no errors for hours.
So in this 7700k system I installed different ddr4 that runs at lower xmp values and all is working again up to 4.5ghz all cores at 1.152 volts. Might have damaged memory controller in 7700k and it won't run higher now due to default high values for vccio voltage and vccsa with plloc levels from stupid board manufacturer!

Because now I can't pass real bench at all even at stock speeds, where as before I was able to pass at 5.2 oc. I can pass every other stress test, including latest prime95 small ffts with 5.2 oc right now still but real bench fails every time. Redownloaded real bench as well, no change. Have had zero issues in windows/games.

I did run 13 instances (have 32gb ram) of memtest (2gb tests on each instance) for about 6 hours and had zero errors. at 5.1ghz oc on cpu. Everything passes and works fine except real bench will bsod no matter what speed I am running at, xmp on or off.Originally Posted by skyhawk21

With 8700K, im rock solid on 140s, its pretty incredible how much smooth BF1 is now with this new cpu

I always use fixed voltage, i really hate how offset or adaptive bounce. It would be marvelous if voltage remained stable across loads, but electrically its almost impossible, so we need LLC to keep the drop to a minimum amount.

LLC exist for a reason, voltage drop. Maybe you arent being affected, but some boards drop voltage a lot, and its related to VRM and caps on board; this is specially true when you are pushing voltages and frequencies beyond intel defaults, some motherboards will drop a lot of voltage. Again, voltage drop is expected.Originally Posted by Knoxx29
Maybe i am overreacting but that is too much for 4.9 considering i am at 4.8GHz 1.20V, i don't understand why you people use LLC, i use LLC just for my X58 Machines, i have never used it for any of my other Machines.

Thing is, windows maybe using AVX for another thing, the way to properly test it is to totally drop AVX from windows and try again. From what i saw, and the widespread issue, it seen there is a bug in CPU microcode that is causing the issue.Originally Posted by amd7674
Is it true AVX clocks kick in when playing some games i.e. Battlefiled 1? From my understanding BF1 is non-AVX game.
I've read users with at least Hero, Gaming 7 and Taichi experience this problem.

Strix have lesser power phases than maximus, so you will probably end with hotter VRMs, and there is plastic cover over vrm heatskink. You should monitor vrm temps and eventually provide forced cooling over it. In the end it boils down to how many power the chip will need to OC, also deliding plays a factor in reducing waste power.

Tom from overclock3d said that the bios shipped with the board had several issues, but its probably fixed by now.Originally Posted by thomjak
Looking forward to getting my 8700K, i had no plan on upgrading but i won a contest on black friday and will be getting a new 8700k rig for free. Hope it clocks good!

yesterday i got the asus rog hero x and g.skill trident z rgb 16gb 3000 cl 14 14 14 34 kit and a 750 watt thermal take rgb power supply gold standard hocked it all up and evrything worked fine , i instaled windows 10 1607 as fall update is crap , got drivers , games , apps , updates done ran some battle field 1 1080p ultra 1000 fps max not 200 nvidia 388.31 drivers on the 10800 ti and it ran amazing
1080ti in 1080p ultra was pretty much 99% ussage most of the time fps was in the 142 - 180 range so much better then the 7700k @ 5 ghz .
rebooted pc loaded up ram over clock to 3600 cl 16 16 16 36 1.4v vccio @ 1.18v vcssa @ 1.22v
5 ghz all cores cache @ 46 load line @ level 6 vcore @ 1.33v stable so far in a quik test of priime 95 26.6 for 2 hrs , asus rela bench for 2 hrs , bf1 ,bf4 ,fallout 4 , cinbench score was 1681
i delided it with liquid metal also under my swiftec h320x 2 360mm aio as well . temps in bf1 were around the 58 -63 c @ 80 % cpu ussage, cpu z stress test for 1 hr was 61 -68 c
pretty happy about 5 ghz 1.33v ram @ 3600 so far better then what i was expecting . i was hoping for 5 ghz no avx offset @ 1.38v or lower so im happy ill try 5.1 and 5.2 ghz later today
