Skylake/Kaby Lake/Coffee Lake (-X) (Z170/Z270/Z370/X299) OC

I use the 6700k with a Asrock Z170 OC Formula motherboard. I was tying to get above 1150MHz for iGPU but I never get results above this frequency. Example: If I tell it to run 1250MHz or one of the predefined profiles in bios (tried 1.70 and 1.90) it boots to Windows bu runs at a maximum of 1150MHz (used GPUz, latest version). If I use XTU instead of the bios I get the same results. Does anyone know what this can be?

lo all, we just completed a two day OC event at the Firstlook event. In 3dmark 06 we noticed that our CPU test on the Maximus VIII was less than the one from the MSI Team. Both setups running Windows 7 64bit. On air 4500/4500 gave 9500ish on the ASUS board with 0201/0007 bios and 10000 points on the TE XPower. We needed to up the core speed on the ASUS to 4700Mhz to get the same 10000 points... we tried other biosses, settings, 3 different Win7 OSses (all 64 bit though) the CPU score output at 4500/4500 remained around 9500-9600ish. On LN2 we could not breach 13K CPU score at 6100Mhz. Looking at some results I spot similar stuff on the bot. What you can …

Just a quick thread to show there is no RTC or clock drift issue with Skylake when changing the BCLK at runtime. Test: Skylake i7 6700K with RTC enabled in Windows 10. Based on the findings described here, we would expect a difference in benchmark result from running 41x100, 40x102.5, and 42x97.6. Specifically, 42x would be approximately 3.4% faster than 41x. In our test we find that: 40x102.5: 8.977 sec 41x100: 8.983 sec 42x97.6: 8.999 sec This confirms with the hypothesis that Skylake isn't affected by clock drift. The real technical reason is that the BCLK frequency is now a separate ICC and is no longer tied to the other clock frequencies.

Hey guys, Asus Maximus VIII Extreme got to me and here are some quick findings: - LLC Level 6 overvolts with 0.025V (BIOS 1.45V, multimeter max 1.475V under load) - LLC Level 7 overvolts with 0.045V I will test the other Levels and let you know. - Memory voltage stays as in BIOS (1.65V BIOS, 1.649V multimeter) - tWR stops at 13 no matter what I set in BIOS. 3200C12 @ 1.7V - OC Panel II is similar to previous, with another firmware. The new firmware can be applied to old OC Panel.

Just wanted to check who's having problems with the tiny PCB of Skylake CPUs bending in the socket after delid? Some folks are talking about it on Facebook ... check the picture below. Anyone else with similar experience?

I've been reading the excellent ROG guide to study up on Skylake extreme overclocking. I'm a bit unsure about the PLL termination voltage. Do you guys see any gains from increasing it significantly? More specifically, gains when trying to improve stability at lower temperatures. I don't really care about the BCLK overclocking capabilities.

Hey guys, Max VIII Impact is here. Very nice board. BIOS is the same with Gene and Extreme. OC memory profiles are there. CPU overclocking same as Extreme, memory a little better i'd say. If you have questions, just ask.

Hey GUYS! I did a lot of testings the last weeks... Spent more than 150L of LN2, hopefully to help you guys, not doing the wrong TIM on your Skylake DIE My testsystem is: Asus M8G Kingston HyperX Predator 8GB 3300C16 @ 3000C11 Seasonic 1200W Platinum Intel skylake 6600K ES Der8auer BEAST as container for the CPU What have I done? I put all the following TIMs on the DIE of the CPU. On the Intel HS I always used Thermal Grizzly Kryonaut! TIMs I've used: Innovation Coling Diamand 7 Carat Prolimatech PK1 Prolimatech PK3 Thermal Grizzly Hydronaut Junpus DX-1 EK Ecotherm Gelid GC-Extreme Noctua NH-1 Thermal Grizzly Kryonaut Then I wen…

Hi folks, Sharing is caring right? Z170A Xpower is very strong on mem, at least on Hynix MFR/AFR (no other kit in my hand). Efficiency is right where it should be. First of all (as usual) : - Find the good temp for your mem. I can run -180° on mine but the best temp is -100°, this is where I can achieve 1830MHz 10-15-15-28-278 and 1870MHz 10-16-16-278 - Find the right amount of volt. Mine do not like more than 1.85v Then you can try the set of timings I found, it is not perfect, but seems to be a good base : With these settings and auto RTL/IO I get 44/45 5/5, sometimes 44/46 5/6. I did a quick try at 5Ghz, this is what …

Its common knowledge skylake TIM is less than optimal, So I had some Indium Foil left over from some previous playing around.... INNNNDIUMMM, very heavy for just a small thin sheet. Its about 2-3 sheets of paper thick. Nice size piece over the die, it shrinks a little when it melts. Melting point is 157c so went well above that. "A rapid cool down is desired to form a fine grain structure. Slow cooling will form a large grain structure, which typically exhibits poor fatigue resistance. The acceptable cooling range is -0.5 to -6.0C/second (-2.0 to -6.0C/second is ideal)." Tried to maintain this using ln2 to cool it back down. Finished …

As you already know Skylake overclock depends greatly on TIM used.It is now more important than ever for both ambient and extreme users to use a quality TIM for maximizing overclocks. Since overclocking Skylake is pretty much apply voltage and frequency and start i made a short test with stock tim versus two quality solutions from Gelid and Grizzly . I used for this a good single-stage made by nachtfalke who kept a steady temperature of -56 idle -53 load on xtu benchmark . Having a steady temperature and avoiding variations helps greatly test data so i have to give credit to nachtfalke for being a great builder and also a good friend Long story short: SIN…

the big question, as it seems even with the great current retail pastes available everyone still needs something better

hey guys, i experienced something weird with latest 1.73 cpuz when trying to save validation files even with Gigabyte or Asus mobos. i was benching 6700k on ln2, and above ~5.5G when i press F7 or the validate button from cpuz tab (extreme oc feature on or off doesnt change about that) got immediately blackscreen and system restart. i guess this new cpuz generates bigger cpuz load during validation process like older versions. anyway since you cannot validate with older cpuz versions anymore you have to modify cpuz.ini file. here are my settings below what i used to take valids succesfully cpu and mobo tab activated only. [CPU-Z] VERSION=1.7.3.0 TextFontName= …

Reference For Die Size and to show no FIVR in the way. Test Used: Wprime1024 5.1ghz 1.48v Before: 96C hit and failed within seconds (hard to tell what load after 2 minutes would have been probably 105+) After: 78C Warmest core and passed :thumb: Under ln2 without Delid running XTU we are going postive temps at -145c hits 20c loaded. :o So I would suggest everyone delid Replace TIM under IHS and then put IHS back on. Skylake bottom Devils Canyon top The PCB is thin and Ive heard of it breaking in a vice, so I would stick to razor. Press in on each of the 4 corners then do the sides last. Vice method fail (not me lol) Al…

I noticed Skylake's stock voltage is a bit high it seems, so I was wondering if our new max voltage that's "24/7 safe" is higher than the previous 1.35v we were recommended by intel. I can't seem to find anything concrete, was wondering if anyone knew. Just curious that's all . Thanks for any help guys, post a source if possible thanks again!

With some help from Neo I joined the DDR4-4000 club! It's too easy on Skylake
