Hello,
i have a solid overclock that is stable (very stress test you can think of and gaming). i can cold boot and reboot fine over and over.
This issue is when any change i make to bios and when i save the next boot the oc is unstable no matter what. i have my oc profile saved to replicate.

for example if i go in and turn secure boot off and save and boot again the pc is no longer stable. to fix i have to clear cmos. then load the same profile and save then its stable again. if i go in and change a setting same thing happens.
i have also made a 2nd profile that is identical to the other profile. the only diff is secure boot off vs on. If i load that profile and save and reboot the system is unstable again. reset cmos and load the profile with secure boot off then system stable again until i make any change in bios and save.

seems something is not saving properly

i have tested thios using the current windows insider build along with stable windows builds, and i have used a few linux distros as well with same effect. unstable and crashing. ubuntu, opensuse, parted magic. same results

this has been going on since i got the board 4-5 bios revisions ago.
265k
z890 carbon
48gb v-color 8000 cudimm ram

fyi i tried to make a ticket with msi, but when i click the submit button nothing seems to happen. so i either sent them the same issue 10 times or they didnt receive LOL

yes on latest bios 1A90. but been doing ever since i got the board. every revision
what about the profile? its 100% stable. it wont stay stable when ANY bios change is made. no oc profile change, just a random bios change
In this instance secure boot on or off caused the system to be not stable without cmos reset then load the profile. making no changes to the oc profile at all.

Again the bios changes im making are not any OC settings, just a regular bios setting like secure boot on and off, or disable onboard sound, or boot list changes.

1- boot and reboot pc with stable profile(secure boot on)- all good in windows and linux
2- go in and change 1 setting (example secure boot off from on)
3- now pc is not stable.. reboot or cold boot blue screens. also linux freexes and crashes
4- cmos reset. go in and load profile that has all same settings as original profile but with secure boot off.
5- system boots and is stable again.

now repeat steps back to secure boot on.

1- boot and reboot pc with stable profile(secure boot off)- all good in windows and linux
2- go in and change 1 setting (example secure boot on from off)
3- now pc is not stable.. reboot or cold boot blue screens. also linux freexes and crashes
4- cmos reset. go in and load profile that has secure boot on.
5- system boots and is stable again.

MSI had tried to duplicate the problem without success. Please attach
- OC profile (saved to USB and paste it here)
- your memory sticker picture
I'll forward it to my contact.

Thanks! i did finally get a ticket open. they said they would report my issue. CSD#1304592
At first they wanted to replace my board, but im 99% sure the board is fine as its super stable if i dont make any changes to bios once set.
Attaching zip with ram pic and profile. Need anything else let me know

reload profile all is working again.

Oops, sorry I absolutely miss your thread, I think I have it open somewhere but anyway, my bad.
MSI replied they cannot guarantee over spec overclocking, the performance might vary across different AGESA code, BIOS version.

over spec overclocking?
i have the same issue if i dont oc the cpu. its not an oc issue its a bios setting saving issue. how can i run my system for months on end and then change 1 setting to and from the same setting then it be unstable?
there are other users with tomahawk having similiar bios settings not saving properly. like vcore- here https://forum-en.msi.com/index.php?...rting-with-bios-version-a73-and-later.414040/

ill honestly never buy another msi board again with how shitty these bios bugs are. Word spreads guys....

I assume the memory is running 8400Mt/s while the spec is 8000Mt/s?
If you have a "simpler" OC profile that can constantly reproduce problem, let me know and I'll pass along.

does the motherboard not advertise 9200 mhz?
again im not sure why this keep getting brought up. the board works at the 8400 speed fine until any change is made. i can change the setting to and from the same value so in the end nothing changes truly, but the board is not saving the setting properly as it will fail next boot until cmos reset and profile loaded again...

Just because it says it can do it with a single stick of RAM does not mean your CPU will support it. Intel only guarantees up to 6400MTS any thing higer is a crap shoot

The board is not the issue 90% postive it is your CPU that is not supporting the higher speeds

Yes, but that does not mean any kit can run that speed.

Then why you sending a profile with memory freq higher than advertised speed?

Just trying to be fair here, your comment assume all CPU and motherboard has the same quality, we don't know if you have a cherry pick CPU etc.
I'm not saying the problem is not there, but from my experience, it takes some time for MSI to confirm the issue.
the problem might be obvious on your side but not theirs.

with your attitude, you will soon hate all the motherboard manufacture :( don't get me wrong, i understand your frustration, but it happens all the time. Just be more patient and give them what they want so they can replicate issue easier.

I've been running this profile for 7 months.
Stable. Stable stable.
System only becomes unstable when any setting is changed...and saved.. and the setting could have no change to the overclock. Example just changing secure boot on to off back to on again.

I'm not assuming anything.
Msi saying OC is the issue...
I've been running this profile for 7 months... no crashes when i dont resave the bios

Stable. Stable stable.
System only becomes unstable when any setting is changed...and saved.. and the setting could have no change to the overclock. Example just changing secure boot on to off back to on again. Nothing to do with the OC

The frustration is msi and how they handle it. It's been almost 2 months.

At least Asus any gigabyte have dedicated forums for each chipset. I will agree support for most companies has gone down hill.

again to let you all know. im running Stable @8400mt
its not a ram or cpu or mobo defect. its a bios save issue. only occurs when making a bios setting save.

"solid overclock" does not exist.

Motherboard capability and CPU IMC overclocking capability are 2 very different things.
Why do you run a memory kit rated (already overclocked) DDR5-8000 at 8400 ???
That's wrong from any point of view.
Do you think v-color are some idiots who don't know what they sell?
That kit was rated at 8000 because it failed certain factory tests at higher speeds (8400 included).
You - a home user - cannot replicate all the factory tests.

Do you have this issue if you run the memory at 8000?
Do you have this issue if you run the memory at 7200?
Do you have this issue if you run the memory at 6400?

LOL
Home user....
ive worked in the IT industry many years We do server Refurbishing ect.
Solid overclock doesnt exist? WTF are you smoking? if there are no crashes or bit errors and latencies are good and its tested this way for 7 months... thats a good solid overclock bud.

Its sad you dont know h many Dims that are made are same chips just sold as diff speeds. also ive tested extensively adjusting timings on the dims to work with my setup.
my dims timings wont be the same as yours or even another kit like mine.

again ive gave plenty of info for msi to look into. im done being a beta tester for them. the save issue is a known problem acrross the z890 platform. most dont see the issue as they use default settings. dont advertise as an overclocking board if you cant make the board save properly.

ive owned 4 overclocking boards in my time (i keep boards for 8 years ish). and this is by far the most issues ive ever seen from a OEM. first and last time MSI buyer

Give people crappy support. customer gets annoyed. company uses them being upset against them to not support.
I also wouldn't trust anyone to help me that says there is no such thing as a stable overclock.
