i9-14900k & Z790 AORUS Master instability issues

[primal thunder]

Having stability issues with this combo, I've tried setting the P-core multiplier down to x55 to prevent GPU out of memory error/BSODs that were happening. I've also tried setting TDP max to 253 for both short/long duration.
Might be time to lower voltages, but I'm unsure exactly how to do that with this mobo. Used to use ASRock and I swapped over to Gigabyte this upgrade cycle.
Pretty terrible that default CPU/Mobo settings causes this.

[warm kraken]

What's the ram speed at?

U sure it's the cpu?

Could be ram instability caused my mobo or cpu mem controller

@primal thunderYo

Same here

i9 14900k and MSI Z790

im also having instability

all bsod pointing towards memoryy

but i already bought and switched rams nothing worked

sometimes nvlddmkm.sys error

[rustic dune]

its Vram

i hope we can try to fix this
its so annoying to get these types of error

my mobo released a bios update to fix this

but im still getting same bsod with memory errors lol

[vivid scaffold]

Are you getting hard crashes? My AORUS elite X AX crashed yesterday and now it won’t post at all. I9-14900KF and gigabyte 4090 gaming OC

[rustic dune]

hard crashes?

sometimes my discord or other apps crashes without a event viewer log

[vivid scaffold]

As in just shuts my PC off no blue screen just straight to black and no power

[rustic dune]

only happened once or twice

[rustic dune]

im pretty sure its 40 series issue

the vram is causing the crash

but windows reports it as memoryy issue

[warm kraken]

Vram?

Vram is gpu

[rustic dune]

ye

the gpu is causing this issue for me atleast

have u seen this nvlddmkm.sys?

in event viewer or during bsod

its driver issue

many ppl having this issue u can look on forums

my gpu is also 4080

[warm kraken]

Yes I have.

My friend had it

And I fixed it by running the cpu core clock.

[rustic dune]

how do i fix this

cpu core clock?

[warm kraken]

Yep

[rustic dune]

elaborate

u undervolted cpu ?

[warm kraken]

Look what is the stop cold when u got a blue screen

[rustic dune]

Memory_Management

driver_irql_not_less_or_equal

[warm kraken]

So it's memory

[rustic dune]

page_fault_in_nonpaged_area

[warm kraken]

Yep all leads to either unstable cpu or ram

[rustic dune]

but

nvlddmkm.sys

is nvidia thing

[warm kraken]

Ignore that

[rustic dune]

how can i fix this

i have exactly same

[warm kraken]

This is why I asked ur ram speed and capacity

[rustic dune]

5600mhz

[warm kraken]

I would do ram stress test.

[rustic dune]

i did

[warm kraken]

If that fails it's the ram

[rustic dune]

.

i have 2 different kits rn

[warm kraken]

5600mhz and what's the capacity

[rustic dune]

having issue with both

32x2

and 16x2

two different kits

im using first one rn

[warm kraken]

2x16 won't work?

Same issue?

[rustic dune]

yea

same bsod with both rams

bios is on default

no xmp

[warm kraken]

Then we run a cpu stress test. Check the cooling and the temp. Then we proceed to undervolt the cpu

[rustic dune]

already did

prime 95 for one hour straight

max temp was 77 degree

[warm kraken]

So we static pin a voltage, p core clock, e core clock, uncore and load line calibration.

[rustic dune]

but undervolting leads to uunstability

[warm kraken]

14900k default 5.7ghz all core. Try to aim smth like that

[warm kraken]

???

[rustic dune]

how to do that

u mean all p cores?

what about e cores

[warm kraken]

I don't remeber on the top of my head

Prob 4.4ghz

Ring/uncore u can do 4.8

[rustic dune]

ok

so its the cpu memory controller issue?

[warm kraken]

No, if what u said is true and u ran hard mem test with no problem. It's cpu core issue.

[rustic dune]

its 100% true

[warm kraken]

Intel try to single core boost high without enough voltage

Like 6 ghz

Then it crashes

[rustic dune]

oh yea my cpu runs at 6 ghz

[warm kraken]

6ghz is one core.

[warm kraken]

It won't run 6ghz all P core

[rustic dune]

why its so high at idle

im only using discord and chrome

[warm kraken]

Idk

[rustic dune]

so 5.7 ghz?

[warm kraken]

I would discord and help but I got stuff to do unfortunately

[rustic dune]

oh ok

[warm kraken]

And I injured myself 2 days ago lower back.

[rustic dune]

should i tryy 5.5ghz

[rustic dune]

Damn i hope u are fine

[warm kraken]

Maybe ask people in the overclock channel how to static pin clock speed voltage and load line calibration

[rustic dune]

get well soon : )

[rustic dune]

alright

thanks for the help

[rustic dune]

2 p cores were at 6 ghz

i changed them to 5.7 ghz

lets see if bsod disappeared or not

[primal thunder]

Hey, so I've tried running Prime 95 and I almost immediately start seeing rounding errors get spit out.

Cinebench R24 will complete the first render, looks like it's about to start a second and freeze.

Tried Intel diagnostic tool, it'll sometimes BSOD while under load.

I've also opened a support ticket with Intel in case I need to RMA. Maybe they'll have a solution.

[rustic dune]

my cpu never crashed during stress test

only while playing games

or using chrome/discord

maybe u have factoryy overclocked cpu

overlocking making ur pc unstable

[primal thunder]

Mine crashes all the time.

[rustic dune]

undervolt ur cpu

try 253W and - 0.20

[primal thunder]

I've underclocked it and set max wattage to 253w to keep power use down.

[rustic dune]

whats ur current ghz

[primal thunder]

55x max

[rustic dune]

oh

u used intel extereme tuning?

[primal thunder]

No, BIOS

[rustic dune]

55x p cores

what about e cores

[primal thunder]

Haven't touched e cores yet

[rustic dune]

https://linustechtips.com/topic/1547316-help-with-underclocking-and-undervolting-i9-14900k/

try doing both e cores and uncore

[primal thunder]

Can try that out after work today. Had been doing some reading on Reddit and various forums, looks like a good number of people got bad chips and had to RMA, might have to RMA as well

[rustic dune]

i see

if u get a full refund go for amd or something else

[warm kraken]

amd?

amd is worse

[rustic dune]

uh

[warm kraken]

I fixed 10+ this issue on amd here at LTT already

[rustic dune]

when i posted this on foruums

everyone bragging me about gettting an AMD

[warm kraken]

I have encountered 10+ amd on this forum and around 5 intel

I complain about amd durability and instability on other discord

I stopped caring when people have this issue and my irl friend in AUS got the same problem

[warm kraken]

This was a 5800X

[rustic dune]

i see

[warm kraken]

u free rn on discord?

[rustic dune]

my 2 p cores were at 6 ghz switched them to 5.7ghz

[warm kraken]

I am free for a bit

ok and do u still crash?

[rustic dune]

yes

[rustic dune]

my crash rarely happens

like once or twice a day

[warm kraken]

....

here lets just do everthing start with ram test

ill dm u

[rustic dune]

why ram test

[warm kraken]

which ram test did u do? Tm5 anta extreme or hci memtest?

[rustic dune]

memtest

and occt

[warm kraken]

so we start with ram test

[rustic dune]

but i already switched my rams two times with new ones

and same issue

so

[warm kraken]

fine then lets static pin voltage

[rustic dune]

i did that

6 ghz to 5.7 ghz

2 p cores

all p cores 5.7 ghz

all e cores 4.4 ghz

ring ratio still not sure its on auto rn

[warm kraken]

whats the voltage? and llc?

[rustic dune]

253

[warm kraken]

and stress test did u do?

253 is not voltage

that is power limit

[rustic dune]

u mean offest ratio?

[warm kraken]

no

I mean voltage

static manual voltage

Vcore

[rustic dune]

vcore

its auto

same with llc

i tried to change them and crashed during stress test

[warm kraken]

so u didnt static pin it

then lower clock speed

[rustic dune]

i did

even more?

[warm kraken]

ok seems like u know what u are doing

gl!

[rustic dune]

are u being sarcastic lol

nah im noob

i just learned this in past 3 days

[warm kraken]

u keep saying I did when u didnt

so gl.

[rustic dune]

my bad

i confused those things

i only changed power limit , clock speed so far

nothing else

[warm kraken]

I can walk u thru on discord I need too see the bios and ur cpu temp when stress test.

[rustic dune]

ok

[primal thunder]

Unsure if it's a memory issue or a memory controller issue on the CPU. Starting RMA process for my RAM and we'll test swapping that out first

[rustic dune]

use one stick at a time

if its ram only one stick will fail ( still not 100% )

maybe both sticks are fauulty

but chances are very low

[primal thunder]

Honestly it doesn't matter, all of the sticks are from one kit and if I RMA I'll be swapping the entire kit.
I'm going to try running the same test with my DDR4 kit from my old PC and see how it goes. If it still fails it's probably the CPU still

[rustic dune]

alright

u are lucky

im still unsure about my issue lol

my cpu can easily pass 1 hour of intense stress test

already checked rams

and still getting memoryy bsod lol

[rustic dune]

its cpu

i tested my cpu with intel application

and it failed
