GA-Z270X Gaming 7, is this reboot normal?

[kamikazee]

Good day,:
We have many memory models higher than 2666MHz validated in our QVL.
We also got one of them, CMK16GX4M2B4000C19 ver4.31 x 4pcs, for checking issue for you.
With XMP enabled, there is no issue to be duplicated, your issue may not be caused by XMP profile after our further check.
Best Regards,

So what exactly does this mean? The last reply I got was that they are 'checking with their bios technician'.

Havent had a response for days now. No new bios versions available either.

I guess they claim they tried with this corsair memory and it behaved as normal and it has nothing to do with their BIOS .. even though they have removed F5 BIOS from their support pages and you cannot download it anymore.

I cannot find any reference to this Corsair Memory they supposedly tested on the Corsair website .. can anyone locate it ? So they are using something very unusual and not mainstream memory modules that Corsair sell retail.  It doesn't even come up after a Google search.. must be test memory only for MB manufacturers.

I think we are being conned by Gigabyte. Disgraceful support.

I think they are not testing the issue the right way.

If you do optimized defaults, then set XMP, and reboot it will work normally. Until you do a cold boot.
Afterwards you get the reboot issue.

They probably didn't test that.
They just rebooted and saw that it was working.

We are very likely not the only ones with this problem. I guess we can only wait for a new BIOS.
In the meantime stick with F4 or set the memory mhz a bit lower (2666mhz)

I just joined these forums to post exactly the same issue on Z270X ultra gaming. https://forum.giga-byte.co.uk/index.php?topic=18551.0 I have been testing for 2 weeks and have the same restart issues with XMP, but also getting bsod's occasional in Win 10 clean instal when XMP turned on to reflect my 3200 ram - my ram is on the compatible list for my board. I have come across others on google with the same issues, appears to afflict all these z2700x series of gigabyte gaming boards. Very frustrating, i dont know whether to rma board for another make or await a fix, will they fix when they say they cant replciate the issue though! I was okay with no wierd restarts or bsod's on F4 for my board as well.

Corsair CMK16GX4M2B3200C16 is the same as mine. Yours has it as compatible on their support list  when I searched on the memory support page..

Hi, XXXXX:

We are checking same memory model and will keep you updated with test result asap.

Please wait for it.

Best Regards,

Good day, XXXX:

Please be updated.

Firstly we must apologize that we don't duplicate issue earlier.

With the specified memory model Corsair CMK16GX4M2B3200C16, we can duplicate issue with XMP enabled to 3200MHz.

BIOS F5, and F6 have issue, F4 doesn't.

This memory is not in QVL of Z270X-Gaming 7, but still a serious issue to be checked in high priority.

We will keep you updated asap.

Best Regards,

At least there seems progress, I think this will be fixed eventually.

We just have to wait.

Also interesting to hear that others with different boards have the same issue.

Hopefully more will post here.
And if you make a support ticket with Gigabyte, give them a link to this thread.

Good to see the issue is now recognised. I suspect all the varaints of Z270x gaming boards have the same 'base' bios as all appear afflicted with the issue. I will hang fire for a week or so before rma to see if the fix appears.

[kamikazee]

Wow thats great to see that response by Gigabyte. It seems we are finally getting there. Lets hope its fixed in the next BIOS update!

I have linked Gigabyte to the thread also many times and am waiting to hear back from them with an update...

Keep us all posted guys! A fix soon we hope!

I have Z270M-D3H and I have same problem with F6 update bios. If I use XMP Profile it shut-off for 3 second after every PC restart. Worse I get stutter in game no matter what RAM speed set to.

I have decided to RMA my memory modules with Corsair but instead of sending them back to Taiwan from Australia at my expense, took the approval email and shipping label back to where I bought it from and exchanged it for another set from a completely different manufacturer -G-Skill which is on the QVL list .. So now no problems rebooting or restarting with XMP Profile 1 enabled .. see attached !!

They only had a 4 x 4gb module in red , which isn't ideal as I prefer black which will be neutral with the RGB colour scheme I have at present which is Purple pulsating colour !!

I have the same motherboard, my memory is on the QVL list and I have same issue.  I hadnt realised it was a bug until I read this thread (I thought it was just how the system updated itself when you make a bios change)

On a similar topic I also logged an issue previously that if I enable XMP default profile with F4 bios the system doesnt boot at all, you have to manually alter the settings (I dont have that issue with F3 bios - I am using backup bios feature to work around this)

I also have the issue that if I fully power off the system the bios doesnt retain its settings

I am surprised that Gigabyte shipped the bios in this state, these seem fairly basic points frankly. I also agree the support progress is poor.

I have 32G gskill trident-z rgb memory F4-3866C18Q-32GTZR  (4*8G dimms)

I am waiting until F7A bios comes out of beta to update primary bios again

hello i have been follwing this thread for a while and i have the same issue  gigabyte  ga- z270x gaming k5  7700k , 16gb rgb g skill 3000 cl 14 , m.2 drive ( bios f7a ) soon as i enable XMP  bam !  comp shuts down instead of retarting then starts again  it kinda sucks , also  i can n ot get  ultra fast boot to work period no matter what always 10 second gigabyte  splash screen , or if i shut that off i get a  megtrends for 5 seconds ,  ultra fafst boot in the windows 10 enabled also
 ueif mode , 780ti supports gop mode , csm mode off , legacy off , intel secure boot on ,  ultra fast boiot is a no go ..... and the shut down instead of restard when xmp is enabled ,

i have found a kinda work around for a short period of time  i do this:  xmp  off  manualy set timmings ,  volts ,  no memmory fast start up ,  reboot and system is fine  retart pc   ( doesnt shut off )  go to bios select ram  boot mode to fast start up reboot , this will work for about 5 or 6 reboots then back to shuting off .

i have not  tried  any bios except for f6 and f7 and am super scared to do the ftp bios down grade as as the system is its not that bad just kinda anoying but livable ,  i dont even know wich  bios  f4 ,f5, will even fix it for me ? like the others  some says f6 is good some says f5 is borked some say f4 is good
hmmm.......

[kamikazee]

Its been quite a few weeks now since F7a beta was released.

Have also not heard from my support ticket in weeks as they say they are forwarding it to the tech team. This issue has gone on for way too long. This board has been out for ages now!! I thought it is only Corsair memory that is affected but may be not.

I also am hesitant to use the FTP tweak and hex edit the bios to successfully roll back to F4. If the next bios version doesn't fix this issue, I may buy an ASUS motherboard for my next build as this is ridiculous.

Gigabyte, fix it!

We are all tired of waiting and shouldn't have to change our memory or turn off XMP to be able to restart the computer properly.

[bass_junkie_xl]

yeah i agree totaly i might sell this gaming k5 board ( i realy like it the look performance )  but if the next bios doesnt  fix the xmp   reboot issue / low oc capabilty  then i guess all of us have to sell out boards  or live with it or take a risky chance and  revert with ftp to f4 bios ...... and hopefully dont corrupt our dual bios
in  the mean time its not that bad  just annoying is all 

keep us posted guys
