FEAR6655 Posted November 4, 2015 Share Posted November 4, 2015 No issues so far with my LPX 2400 C14 kit at XMP on a Z170 Pro Gaming. Kind of glad I went for low frequency, low CL memory now. Hopefully the issues with higher speeds get resolved though, at least ASUS is actually pushing out BIOS updates, rather than nothing at all.

Rogue Nano Posted November 5, 2015 Share Posted November 5, 2015 After updating my BIOS the XMP problem has gone away. Everything is stable and Memtest is reporting no errors after running overnight. I imagine it's just a matter of time for a lot of z170 board owners for the BIOS to be tightened up. Link to comment Share on other sites More sharing options...
r-Z Posted November 5, 2015 Author Share Posted November 5, 2015 Quick update. Updated BIOS to 908 on the Z170 pro gaming motherboard. Still not able to run XMP profile 3200mhz as specified. Can run a stable 2800. far cry from 3200 but it is what it is. Hoping for consistent bios updates that will eventually resolve this XMP issue.

Yeah same issue here mate, 908 bios wont run at 3200 but 2800 is fine! any higher and it tends to not boot correctly Link to comment Share on other sites More sharing options...
Eldata Posted November 7, 2015 Share Posted November 7, 2015 Yeah same issue here mate, 908 bios wont run at 3200 but 2800 is fine! any higher and it tends to not boot correctly Do this; 1. Press F5 key while in BIOS to load optimized defaults 2. Press F10 key then OK to save and reboot 3. Choose XMP Ai Overclock Tuner setting while in BIOS 4. Move down to "DRAM Voltage" field then type 1.37 <ENTER> 5. Move to next field "CPU VCCIO Voltage" then type 1.20 <ENTER> 6. Move to next field "CPU System Agent Voltage" then type 1.20 <ENTER> 7. Press F10 key then OK to save and reboot Repeat steps 4, 5 and 6 above using just the (+) key to increase voltage one press at a time if you still have issues.

This frequency does not change our motherboard, it does not make an adjustment. z170 pro gaming. Can you show the pictures automatically change its settings by going back to get out of there.

Yeah tried all that last night, made no difference at all. Went up to 1.25 on VCCIO and the System Agent and 1.37 on DRAM voltage and it still refuses to boot! so still running at 2800 with my not so fancy 3200 memory! Greybeard you owe us some answers or an update atleast now as this thread is expanding and you haven't said a word in ages on this topic. update please!!

That board has similar XMP issues with George Skillful memory as well. Asus claims it'll be addressed eventually with BIOS updates. You have confirmed that increasing the relevant voltages isn't a workaround for that board. It is for most other Z170 boards with that issue.

Smitty27 Posted November 10, 2015 Share Posted November 10, 2015 I updated my Maximus VIII Ranger today with the latest BIOS, 1102. My corsair memory still won't boot on XMP. The BIOS release notes just said improved stability. Link to comment Share on other sites More sharing options...
styrop14n Posted November 11, 2015 Share Posted November 11, 2015 Hi Guys Exactly the same issue here:sigh!:, Mobo Asus Z170-A (BIOS 1203 latest) RAM Kingston DDR4 2666 4x4GB C15 (HX426C15FBK4/16) yes i know it's corsair forum and Asus z170 pro gaming mb thread, however the issue\symptoms are regardless ram/mobo, its seems as Z170 chipset or mobo issue. 1st step : XMP 2666Mhz - no errors 2nd step : I've found this thread http://www.overclockers.com/forums/showthread.php/762169-Kingston-HyperX-FURY-16GB-DDR4-2666-CL15-HX426C15FBK4-16 so I setup my RAM 3000 15-15-15-35 1N 1.30V and is 100% MemStable i can run 8h test and there is no errors at all :!: System is stable games/all memory/cpu test etc... However as NJC mentioned "cold start" is total lottery, sometimes boot up sometimes won't :evil: waiting for another Asus BIOS.... :[pouts: Link to comment Share on other sites More sharing options...
LegolasYiu Posted November 16, 2015 Share Posted November 16, 2015 Tips for memory issues for Asus motherboards. I use it a lot. Upgrade to latest BIOS than, I usually check the timing on the Corsair website and set on the BIOS manually. For example: Memory Size 16GB Kit (2 x 8GB) SPD Latency 15-15-15-36 SPD Speed 2133MHz SPD Voltage 1.2V Speed Rating PC4-25600 (3200MHz) Tested Latency 16-18-18-36 Tested Speed 3200Mhz Tested Voltage 1.35V AI Tweaker -> DRAM Frequency -> (DDR4-3000) DRAM-> Select Timing Control 1) DRAM CAS# LATENCY – 16 2) DRAM RAS# to CAS# Delay – 18 3) DRAM RAS# PRE time – 18 4) DRAM RAS# ACT Time– 36 Return to Extreme Tweaker 5) DRAM VOLTAGE – 1.35V (0.1V+ if it is still unstable) Save settings and reboot Link to comment Share on other sites More sharing options...
NJC Posted November 18, 2015 Share Posted November 18, 2015 Yup! done all of the above, pretty much pointless with the state the current Asus Z170 boards are in, yeah if i was running some slower memory it would be fine but trying to achieve 3200 speeds just seems impossible until they fix it with some bios updates, if thats even possible! starting to doubt it atm.

emissary42 Posted November 18, 2015 Share Posted November 18, 2015 It is not like all ASUS mbs have problems running high memory frequencies, at least i can reliably POST with 4x4GB Corsair Vengeance LPX CMK16GX3M4A2800C16 overclocked @ DDR3-3333 16-16-16-35 1T 1.36V on Maximus VIII Gene. For that i only had to manually tweak VCCSA and VCCIO pretty much. Also i don't think you should use the voltages Eldata gave in #55 for VCCSA and especially VCCIO. If i raise them this much, that results in infrequent blackscreens on my boards HDMI out. So either one or both are are probably way too high.

Corsair Employee Greybeard Posted November 18, 2015 Corsair Employee Share Posted November 18, 2015 Greybeard you owe us some answers or an update atleast now as this thread is expanding and you haven't said a word in ages on this topic. update please!! Alright, I just got an update from our DRAM, and according to them, Asus is fully aware of this XMP profile not loading properly in BIOS with Z170 boards. From the sound of it, a later BIOS rev will address this issue. In the meantime, for those Z170 owners that have a kits that's rated at 3000-3200, you guys can RMA those kits and we'll get them replaced for you. I'll provide more update as they come along.

ztjuh Posted November 21, 2015 Share Posted November 21, 2015 (edited) Z170 PRO GAMING BIOS 1102 is out (Improved system stability), anyone tested it yet? I'm still running 0703, which seems the most stable for me. With the same settings on a higher version of the BIOS it won't boot due to the XMP profile, I can get it to 3000Mhz with this BIOS.

I have ASUS Z170 PRO GAMING and Corsair CMK16GX4M4B3000C15. I also have the same problem in XMP. BIOS 0802 can solve the problem. See my solution. BIOS 0803 can solve the problem. See my solution. BIOS 0908 No luck. XMP causes "Overclocking failed". BIOS 1102 No luck. XMP causes "Overclocking failed". My solution is: Change Fast-Boot to disabled. Change VCCIO to 1.175v. Change VCCSA to 1.225v. Save and reboot. Change memory profile to XMP. Save and reboot. Link to comment Share on other sites More sharing options...

ktp Posted November 22, 2015 Share Posted November 22, 2015 Ahh you don't have 3200Mhz, I can get it up to 3000Mhz already without changing IO or SA. Yep, mine is 3000MHz. But the results are different by bios revision. Using rev0703, my memory works fine with Fast-Boot=disabled only. without increasing IO and SA voltage. In short, I would like to say: Fast-Boot=disabled may increase boot stability. Only works with older bios?Increasing IO and SA voltage will give us some stability, but it is not silver bullet. Recent bios will give me worse result in XMP. ASUS mobos will not boot correctly even if we choose their QVL memory :-P Link to comment Share on other sites More sharing options...

You seem to be overclocking already overclocked memory and using the iGPU. Most guys here are just trying to get the advertised XMP setting to work.
