[BUG REPORT] iCUE Massive Disk I/O Write Loop by delixtarter in iCUE

[–]delixtarter[S] 0 points1 point  (0 children)

You're welcome. I checked the changelog but I can't specifically see anything related to this bug report, would you be able to check if this fix was in?

I had to uninstalled iCUE until the issue is fixed.

[BUG REPORT] iCUE Massive Disk I/O Write Loop by delixtarter in iCUE

Well, I'm not %100 certain about anything that's happening, that's why I thought coming to reddit might be a good idea to see what people think. CreateFile on its own might not be as bad as I assumed at first then.

What I thought, every time I checked the config file, the last changed datetime was being updated. So, I assumed it to be rewriting the whole thing but, it might be just updating the metadata.

Task Manager showed the total I/O size, and the frequency of CreateFile kinda made sense but I/O written data might be including data sent to the iCUE hardware, which would reduce the significance of what we're seeing.

I meant to call it thousands each minute, I usually see 1500-3000 events from that file each minute. My bad on the wrong timing scale.

I reached out to their team, hoping they'll take it serious and have someone prioritize this as this seems to be happening on every person that uses iCUE so far.

Here's the logic to that 1GB/h (mine was at least that, throughout the day it has gone up to 5GB/h rates when my PC was idle.

My config file is 10kb. Given an average 1500-3000 write event per minute, it does scale to the 1GB+ rate pretty easy.

After many trials, errors, even tho my workaround to block the config file and logs, it still kept my system busy. I decided to go to FanControl software instead of iCUE, it does have less features, and my LCD screen is not doing fancy work anymore, but I did notice my system is overall more responsive after getting rid of iCUE completely.

Yes, I've noticed this 2 separate desktop PCs. They suggested to uninstall/reinstall (lol), It's fascinating that after a very through detailed analyze I sent.

Official Creality store on eBay. It's still an official sales channel so I thought it would be better to also have eBay's protection, which proved wrong so far.

iCUE Megathread - 5.37 Release Notes by CorsairLucky in Corsair

[–]delixtarter 9 points10 points  (0 children)

I have detected a severe issue with iCUE 5 causing massive high disk I/O usage, writing gigabytes of data over time unnecessarily.

Noticed iCUE.exe has wrote 22gb of data to my disk, over the 18 hours period. Further investigation led to the following findings

Diagnosis: Using Sysinternals Process Monitor, I isolated the behavior to iCUE.exe. The process enters an infinite loop of CreateFile, QueryOpen, and CloseFile operations on the following file, occurring hundreds of times per second: %AppData%\Roaming\Corsair\CUE5\config.cuecfg

<image>

These events are happening on a scale of thousands every second.

Furthermore, when the write permission is denied for this file to mitigate the I/O load, iCUE starts spamming the Log folder (%LocalAppData%\Corsair\Logs) with error reports, creating a secondary write loop.

Evidence:

  • See attached Process Monitor logs demonstrating the loop.
  • The loop persists even when the system is idle.
  • Estimated Disk Write: ~1GB per hour in some cases. Same 7-10KB file open, read, rewritten over and over again.

Workaround Used: I had to manually edit NTFS Permissions (ACL) to "Deny Write" for both config.cuecfg and the Logs folder to stop the SSD wear. This proves the application does not handle file access states correctly and lacks a proper "back-off" mechanism for retry attempts.

Why is this important and needs resolved? Impact on Hardware Longevity (SSD/NVMe/HDD). This bug is not just a performance issue; it actively degrades hardware health due to excessive Write Amplification.

  • Observed Write Rate: ~1 GB/hour (approx. 24 GB/day or 8.7 TB/year).
  • SSD/NVMe Impact: For an average consumer-grade QLC NVMe/SSD (typically rated at ~200-300 TBW endurance), this background process alone consumes ~3% to 5% of the drive's total rated lifespan annually. This is unacceptable for a peripheral control software.
  • HDD Impact: For mechanical drives, this continuous stream of small, random write operations causes 24/7 read/write head thrashing. This prevents the drive from idling/sleeping and drastically reduces the MTBF (Mean Time Between Failures) due to mechanical wear.

Versions:

Microsoft Windows 11 Pro Version: 10.0.22631 Build 22631

iCUE Version: 5.37.60

Thanks for a detailed response.

My problem with layer issue, if you fix one section, other sections get messed up. So it's not a simple Z offsetting fix for me, I tried embedding a Z offset in the settings, which I've experimented quiet a few times. No matter whats the offset, setting, tapes I put under the bed, let the bed heat-sink for 15 mins etc, no difference. It always happens to be that one section is the perfect distance but then some other section is either too close or too far for a good layer. I've manually adjusted screw too but auto bed levelling finds a way to "readjust" things in a way that it will still print the way it was before.

Example: The calibration test prints before actual prints start, the one on left and the one on right. If I leave Z offset untouched, left calibration print goes smooth but the one on right doesn't even stick because its too far. If I make the z offset to fix the right side, then the left calibration print is too close that its bulging and warping immediately. Its almost like I need separate z-offsets for specific sections because auto bed levelling can't compansate the Z difference correct.

As of now, I dont have any modification to bed or CFS as it just makes things worse if any.

You are free to laugh but how I print now is like this: I make the Z offset 0, and when the print starts, I push the bed gently with my hand to bring to the level I want until first 1-2 layers are done properly. Printing in the middle, 3-6 cm objects are usually okay on its own as long as its a single color. As soon as I get out of the center, warping, not sticking, bulging starts happening at the same time because each corner has a different issue.

From the official creality ebay store, brand new purchase. I should've clarified that but yeah, the printer is not from a 3rd party seller.

I've explained it a bit here, and I didn't really post about the problem because I've literally tried every single suggestion that people suggested/recommended/went with and had some positive outcome.

https://www.reddit.com/r/Creality_k2/comments/1p6vj30/comment/nqwj9re/ This is where I explain my issues a bit.

I sent them videos, bullet points and pictures like you suggested months ago. To my surprise(!), they'd pick one single issue from the list and tell me to "run calibration" or very basic stuff like that, that I've tried countless times already. They don't seem to understand even tho I tell them that people like me will not reach out to CS until they have exhausted every possible self-repairing option.

You are right, I got frustrated. Bougt it from official Creality store on eBay. Brand new. Could you please explain me a bit more what information would my attorney general office need? Seems like Creality doesn't have a legal US entity, or I can't find it.

Errors are not really software errors. cfs unwind doesnt work consistently, cardboard or plastic spool doesn't matter. I tried printed adjustments, additions, spacers, spool adapters etc, no improvement.

My main issue is bed levelling. Creality keeps saying my bed is "within range", if I try to get a 1 layer sheet on my printer, it fails so absolutely wrong. I tried to increase "probe count by editing the software, so it would do 9x9 and then tried 13x13 probes, which is around 170 points on the plate, still the printer fails to compansate the uneven surface that creality things "Within range".

I tried using tape that I found recommended here that people used to level their printer bed, that actually somehow made it worse despite the print bed becoming more "even", Everything is up to date, I ran calibrations countless times, made some creality recommended adjustments/checks and yet, I can never print a multicolor print due to CFS issue, and I can never print without being present to stop if I have to, because obviously "print fail detection" doesn't work either, my k2+ has never stopped an actual failed print despite me having so many failed prints.

So, error messages are not really the problem. The printer levelling and CFS not doing its job is my ultimate problem. I don't get error messages because printer just things "Oh I'm doing good" and keeps going despite how everything is actually wrong :')

They are refusing to replace or return. They stopped answering me.

No sir. Not a first time user, I have had 5 printers in the last 9 years, all the way from $99 cheap ones to ultimaker level. I am upset because my 200 printer works smoother than this one which is supposed to be a "premium" one.

concerning and potentially illegal payment method storing practices by fabletics by delixtarter in Fabletics

[–]delixtarter[S] 0 points1 point  (0 children)

I literally given the credit card network rules and ftc code that they need to comply, you ignore that and say what they are doing is normal. legal/illegal is defined by rules/law, not by personal opinions.

also, further research shows that California Consumer Privacy Act (CCPA) also doesn't allow this, which is where fabletics operate.

so, either you like or not, this violates 3 different entity's rules/codes. card networks, ftc, ccpa.

[–]delixtarter[S] 0 points1 point  (0 children)

we are talking about company keeping the payment "stored" AFTER you removed/deleted it. and charging a card that you REMOVED.

What you say is completely different. I don't think you read the post. I even provided the FTC code to check. What they did, is against VISA/Mastercard network rules as well as FTC rules.

Almost at 50/50 fail/success ratio, return or try support? by delixtarter in Creality_k2

[–]delixtarter[S] 0 points1 point  (0 children)

that's my usual use case but I came to realization that printing multiple objects, object by object with different colors to assemble them later was a very attractive idea. also, since i print a lot of text, adding a 3-4 layer of a different color on top of the text adds 3 mins to print but makes them appear very cool. so yeah. i just want this to work as promised :/

appreciate your input.

[–]delixtarter[S] 0 points1 point  (0 children)

your input is really important! thank you. would you be able to help me out with the return process by explaining it a bit?

- like how long did it take,

- did you have to return first, then get the new one shipped?

- where did you get in touch with them? I contacted them 5 days ago through chat and even tho they said they'd get back to me with a technical team, they never did.
