I might as well post my issue here since i have a Asrock Z890i Nova itx pretty much same BIOS as the mb on this thread.

Issue:
XMP-1 = 8800mhz works just fine no issues did ram tests incl Memtest86=pass, Prime95 stressing IMC and RAM option = pass for 1 hour, OCCT extreme data preset 1 hour = pass, Windows memory diagnostic = pass,
XMP-2 = 6400mhz works also just fine.

However it sometimes crash on Elden Ring and Cyberpunk checked windows event viewer both have the Error id 1000 and 0xc0000005 so maybe my RAM isn't completely stable.....even tho the tests i did showed "good"...

Anyway i enable intels default setting and XMP-1 8800mhz then i manually LOWER the frequency to say 8600mhz or 8400mhz or 8200mhz and 8000mhz just to check if any of these lower frequencies are more stable. But i can't....upon opting for say 8400mhz it does 2 BOOTS then a message pops up telling me "normal boot failed with the current settings" and then it boots to Windows but with a severe freq penalty = 4600mhz if im not mistaken. When i restart it happens again system boots twice.

I mean i know this shouldn't be an issue by just enabling XMP and lower the frequency manually without touching anything else.
Am i missing something here like an option inside BIOS that i need to disable or enable to get rid of this weird boot issue.
Like i said XMP 1 and 2 no issues....

Help would be very appreciated.

Anything else touched?? NGU, D2D, CPU clocks?

Nope....
However i found the damn culprit it's the latest BIOS that has the "Intel 200s Boost" no matter what i did and i did NOT enable 200s boost. Just enable xmp 1 = 8800mhz 1.45v then lower frequency to 8600 - 8400 - 8200 - 8000 and all failed i think its due to the BIOS with 200s boost. Because enabling it with my xmp profile wont work it will boot twice then tells me "unable to properly boot with current settings" even tho ive read that it should AUTO downclock my ram to 8000mhz at 1.4v but it doesn't. G.Skill told me that my CUDIMM isn't compatible i guess some have luck while others don't or they use regular UDIMM ddr5.

Anyway for others who might have the same issue with 200s boost BIOS with their CUDIMM kits...
I downloaded the second latest BIOS from Asrock for my mb. And lo and behold i can finally enable XMP-1 8800mhz and downclock it to 8200mhz or 8400mhz and it boots straight to Windows!!
So the culprit = latest BIOS with intels 200s boost for some weird reason it wont allow you to downclock freq when enabling XMP even tho i don't enable 200s.
 
#2,584 ·
Stick to 2.26 bios for itx nova if you don’t want to use 200s.

They are just not testing the bios releases enough. Latest bios for me - set E Core voltage for 1.250v, and it sets it instead to 1.280v. Didn't do in previous release. I am having to manage my cores in XTU. Ram good though.

Small question will i see a noticeable fps gain using 8800mhz vs 6400mhz on 1440p resolution gaming? Finetuning 8800mhz is time consuming plus may be unstable. Im asking this because 200s boost worked with xmp2 6400 latency was 76ns vs my 8800mhz 77 - 78ns (no 200s boost).

What would you guys say just use 6400 with 200s boost and call it a day.
Unless 8800mhz trully gives me like 20 fps or more....lol
So far the difference between 8000mhz and 6400mhz from people (not these silly clickbait videos on yt) the difference is kind of small on higher then 1080p rezolutions or they didnt fine tune it.

Your feedback is welcome or better tell me the difference if you tested it in 1440p and 4k.

If my xmp 8800 is "stable" with the tests ive done: Memtest86 - pass, Prime95 1 hour of ICM + RAM stree pass, OCCT extreme data stress 1 hour pass.
But crashes inside Elden Ring usually after 2 hours same on Cyberpunk error ID 1000 and 0xc0000005 for both.

Do i need to up the VCCSA voltage this is also called "system agent voltage" or does Asrock uses a different name?
Then change to 1.3 to 1.4v just a simple change or must i use something like "override" or "fixed"?
Weird thing is under HWinfo SA is already at 1.408v and thats with intel default. In any case if i do change must i use asrocks extreme profile or keep it at intel default?

No one told me to do that until now, everyone always just said d2d and ngu, and I only got half of them to work.
Does 200S profile boost ring too?

You have to put in a voltage for NGU for NGU ratio to work. Click on OC Tweaker, then CPU DLVR Config, then change the NGU memory fabric to override, then below that change it to 0.950. Just like chibi said but yeah, it even says not setting it disables NGU ratio.

And if you upgrade to 3.03 it will limit NGU and D2D to 32, so thats also your problem. Just went through this fiasco the past 30 min lol just went back to 2.28, all is well again.

Do you still get crashes if xmp is disabled? OR just run the veii provided TM5 link at all stock settings with either xmp I or II untill it completes to rule out ram issues completely. run TM5 with hwinfo open only. IMO memtest86 is not even worth using. my 285k on an apex isnt stable at default 8800mhz xmp (im on air though) so yours prolly might not be either. just ease of mind to run tm5 to rule it out, post the screenshot here once ur done.

if ur passing veii provided TM5 and OCCT CPU extreme 1 hour, i would look into the potential GPU issues then

DONT run both tm5 and occt together run tm5 first then once its done OCCT

Ok i will do TM5 provided by Veil it's a weird program. So just downlaod it, extract then hit use it without any modifications it will run automatiocally correct?
I will do TM5 one hour

Hello,
Download, extract the zip
Run the exe with admin permissions'
Confirm first time UAC check.
Wait till it finishes and don't touch the PC while it tests

It takes as long as it needs to take.
2x24GB approx. 2:40h
If it freezes a cycle, it means your cores (or D2D/NGU) are unstable.
In-case of errors ~ screenshot the first collected errors, so people can help you.

I used the following setup:
Asrock's Extreme profile power plan.
XMP-1 @ 8800mhz - Gear 2
VCCSA - 1.3v

Ycruncher VT3 one hour - all 30 interactions 1.35 * 10 10 on every interaction and no errors
Memtest86 - 6 hours in total and no errors
OCCT Large dataset, Extreme Preset - 1 hour no errors

Karhu RAM test 6+ hours result:

Then used TM5 and look here an ERROR at 0:21:23 in the test....

Font Number Software Technology Screenshot


Then i had no option but to go to BIOS and enable Intels default and did not touched anything else just strictly DEFAULT (save exit) and ran TM5 again result = no error in one hour:

Just in case i ran for GPU:

3Dmark - Time Spy Extreme stress test full 20 loops: no error.
Heaven Benchmark - no errors nor could see artifacts.
OCCT 3D Adaptive result: no errors

So what can i do now SKIP 8800 xmp and try XMP 1 @ 8800mhz but lower it to 8400mhz and check for stability? Or can i do something else without using to agressive voltage. I just want to have a good speed on my CUDIMM that i paid a hefty price for i would be content with speed range of 8000mhz - 8400mhz nothing to fancy as long as it is stable during gaming sessions.

EDIT:
Currently testing with help from G.Skill tech support ie cas timings and 1.4v on vdd and vddq 8400mhz with TM5 fingers crossed........
Done testing at the following settings provided to me by G.Skill tech support he provided me with different CAS settings 2 settings for each of the speed settings ie 8400 - 8200 - 8000mhz. And followed what you told me here are the results hope they are more positive because they are a PASS.
Run Intel Default enable xmp 8800 but downclock to 8400mhz see also ""Asrock Timing configurator" for the CAS timings and VDD and VDDQ both at 1.400v instead of 1.450v. Everything else on default results with TM5 and OCCT cpu extreme test:

So in essence my 8800mhz xmp was deceptively stable on most other ram tests incl Karhu but failed with TM5....
Now with the 8400mhz profile it did better no errors same on OCCT extreme cpu test what are the next steps just want a tad bit lower latency and maybe enable "Asrock Extreme Pprofile" or should i skip that and enjoy this setup for gaming with some easy to follow tweaks? Im so tired off to bed!

Thanks for the help.

Time does not matter. Bigger capacity, longer runtime.
Fails on 24th cycle?, still a fail.
It is not a discharge config.

If you want to target my targets:
TM5_1usmus_v3-25
HCI/Dangwang 1000%
Karhu 20 000%
Passmark Memtest full run 3-4 loops (loop 2 and 3 are full loops, loop 1 is short loop)
Y-Cruncher all tests, 4 loops minimum

If you want to target industry targets:
12-15h discharge-config testing
Y-cruncher 6h

With physical hardware validation,
24h mem-testing.

Lazy validation:
1usmus_v3-25 full
OCCT extreme variable , demo = 1h
y-cruncher FFT, FFTv4, VST, N63 ~ 90min
Karhu or Dangwang or Passmark ~ pick one, all will take ~6-8h for 2x24

Fail-Examples:

One pass, doesn't mean other pass, doesn't mean long term pass :)
Different applications with different strengths for different testing focus with different avg-coverage requirements.

Hi,
for this test:
I used the following setup:
Asrock's Extreme profile power plan.
XMP-1 @ 8800mhz - Gear 2
VCCSA - 1.3v

try default SA. prolly too low. around 1.4 seems to be good for 8800mhz in my experience. EDIT: also noticed that d2d and ngu is at 30/30, is vnnaon set at 0.85 here?

on AIR, Ive had countless issues trying to get anything higher than 8000 tuned REBOOT stable. even with manual ODT's and vddq training off. 8600 tuned profiles which were stable for 1-2 weeks end up being unstable from a random reboot.

Stable here for me is: TM5 25 cycles, 12 hours of karrhu with FPU stress/ cache on and 20 minutes of vt3. for MEM. for CPU OCCT CPU extreme steady load for 30mins to an hour

the 8400 profile you have should be fine ig, dont think you should have any issues IMO with reboot stability since its just xmp or default values. (someone more knowledgable than me could chime in here tbh)

on my apex, with 8800mhz v-colors TMXFCL2488842WSK INTEL 200S BOOST was unstable. my NGU cant do 32 at 1.2VCCSA.

So in the end since i settled on a tuned 8000mhz cl38 profile that has been running with 0 issues for almost 2 months now. im posting the timings below if u want to check it out or use it. 8000 theoretically should have no issues with any 1DPC board. if your watercooling ur sticks u can do higher than 8000 with quite ease prolly.


here is my 8000 profile if u to see if it works on ur system. (it should be better than all stock 8400mhz. someone more knowlegdable than me can chime in here)
VCSSA is set to 1.35 in bios with SA load line at 8 (for asus).
MEMORY: vdd is 1.46(0.01 needed for karrhu to pass) vddq(1.45)
IMC: memvdd = vdd2 so 1.46
VNNAON is set to 1.0 with high d2d coldboot work around enabled. D2D: 36, NGU: 34, Ring: 41 (auto voltage 1.2ish) my ring cant do 42
for P cores followed skattebench guide. (i did not set adaptive voltage though)
E cores: all core 49 at 1.2V, my e cores cant do 50 all core no matter what voltage i give it.

remember turn of all fastboots in bios.

Electronics Screenshot Electronic component


and lastly here is my hwinfo if u want to see any other voltage.

Number Technology Software Screenshot Video Game Software


dont do mem oc and cpu oc together. do mem oc first. then cpu oc.
and i would not reccommend leaving P and E cores to auto voltages. since auto voltages for me was 1.31 for 49 all core E cores and 1.373 for 55 all core P cores.

hope u get this sorted out gl.

EDIT: oh and lastly, if you installed windows with XMP on, please reinstall windows without any XMP on. since intially it was unstable. also dont forget to do some powercycle tests inbetween all testing, (turn the PSU off and press the power button like 4-5 times and turn it back on after a minute). otherwise it behaves really weird

Thanks man,

Slowly learning the basics just want a system that is stable i don't mind 8400mhz i mean i won't notice that 400mhz decrease anyway in games.
So should i bump D2D and NGU to 30 or 32 or first do further RAM tests to see if my current settings is stable is this with or without Asrocks extreme powerplan?

Karhu 20.000% amounts to 7 to 8 hours correct? If so will do that soon.
Y-cruncher 6 hours --- what should i enable for the tests?
TM5 1usmus_V3-25 amount to a liitle bit over 2 hours
OCCT extreme variable , demo = 1h

and i would not reccommend leaving P and E cores to auto voltages. since auto voltages for me was 1.31 for 49 all core E cores and 1.373 for 55 all core P cores.

hope u get this sorted out gl.

EDIT: oh and lastly, if you installed windows with XMP on, please reinstall windows without any XMP on. since intially it was unstable. also dont forget to do some powercycle tests inbetween all testing, (turn the PSU off and press the power button like 4-5 times and turn it back on after a minute). otherwise it behaves really weird

Thanks for the reply man,

I did a fresh install of windows 11 Enterprise iot LTSC without any XMP i first done all the latest drivers then latest windows updates and some tweaks in windows then i enabled xmp.
I wont touch cpu OC yet until im sure my RAM is stable
Should i with the current setting ie "Intels default power plan" set the VCCSA to 1.3v? Or use Asrocks extreme profile power plan?
And should i already set D2D and NGU both at 30 or 32?
I did not changed vnnaon to 0.85v yet was focused on RAM stability first but should i stilll change it regardless?

you can use either asrock extreme or intel default, upto you. i use extreme.


i think asrock motherboards do a pretty good job with VCCSA at auto i believe? i cant speak for that since i have an ASUS but i would keep VCCSA at auto.

the reason i asked for to see if vnnaon was set at .85 is because if d2d or ngu is not stable the memory tests will show errors. for 32 d2d vnnaon might require to be 0.85.

if you want to increase the freq for:
d2d = vnnaon
NGU = vccsa. (ngu voltage exists seperately too? i havent played around with that i just increase vccsa)

since 8800mhz xmp stock is not stable. you could either try to get 8800mhz stable, or use the 8400mhz profile which u have right now (if it passes all stability tests) or try the timings and voltages i posted with for the 8000mhz profile and check for stability. you can choose which ever, the easiest route will be the 8400mhz all default timings ig.

since you currently have 8400mhz looking like its stable. i would work on that. get 25 cycles of tm5 done, however long u want karrhu, and some vt3. and then increase d2d and ngu freq with their corresponding voltages and check with tm5 again.

since most timings are stock 8400mhz should really have no issues passing tbh
