Assuming this is like everyone else reporting this weekend, CUE 5.18 is unable to detect the RAM as a controllable device for some users. The root cause is unknown, but it is version specific and standard steps like clean installs and repair installs don't seem to work. The RAM is detected on the initial installation, the software module downloaded, but the RAM will not be visible in CUE. No known solutions or workarounds yet, except to roll back to old CUE 4 on the main Corsair/downloads page. Be aware this is not a good tactic if you have any new CUE Link gear, Titan AIO, KBs, mice, or anything else released since Jan 2023 when CUE 4.33 was written. Answer from X-TAC23 on reddit.com

r/Corsair on Reddit: I cannot edit my Vengeance RGB Ram in the iCUE software. How do I fix this?
August 25, 2024 -

Little more info. iCUE ran into this problem where it disappeared on my desktop, but the application and other instances were still on. Booted into safe mode and deleted all instances of Corsair. Went back into normal windows, reinstalled and now I can't edit my RAM lighting.

The iCUE software recognizes the RAM in updates, it just stops me from making an edit to the lighting. As of right now, it's stuck on the system lighting and not the iCUE lighting.

r/Corsair on Reddit: I'm back to Corsair.. and there's just no perfect software solution out there for PC hardware ecosystems
February 25, 2025 -

Hi,

I wanted to discuss iCUE related software with you all, as now that I've tried other brands I came to realize that nothing is truly perfect and that the neighbor's grass isn't really greener.

I've had a full Corsair eco system for around 5 years, including case, fans, keyboard, mouse and even a few other things like mouse pads. When everything worked it was great. However I always had weird issues with iCUE: it uninstalled itself multiple times, the default fan curves didn't work (creating a custom one did work), some fans led's started misbehaving (I never RMA'd them for the hassle, and sometimes they went back to working well again by themselves).. So when the opportunity came to make a new build, I was very excited to leave Corsair and move to a different brand. That turned out HORRIBLY.

I went with the most popular brand these days (Taiwanese) that has some really cool aesthetics. First thing I noticed was that their software UI was quite outdated compared to iCUE, but whatever - no big deal. As long as it works I'm happy. Then a week passed and the issues started. I'm still to this day not sure exactly what happened (seems like their software automatically tried to firmware update the fans and it failed midway) - but suddenly all 7 of my fans started having issues at random. Nothing I did to troubleshoot it worked, and after filtering out the front page that's full of pics posts in their subreddit and looking for people with issues - I've suddenly realized that there were TONS of people experiencing issues, and saying how bad the software and RMA customer service is. You just had to look past all the cool pic posts.

I tried to RMA them, which they accepted fairly quickly because apparently the fans going crazy from a random automatic firmware update is a thing that happens.. and it took 3 months from them authorizing it to shipping it out. Yep, you heard that right; 3 months from acceptance of RMA until they finally shipped the new hardware (+ a few weeks for shipping). I live in NA. During that time they also didn't reply to my emails. I had such a horrible experience that I ended up just selling the whole thing and making a new build now.

So where does that leave us? I can try a different company, but there really aren't many that do AIOs and fans at the same time, and we know that all of the big Motherboard companies have very bad reputation and issues with their software (Armory crate anyone?).
So there's really not much left. Reading the megathread here wasn't easy - people are complaining about the titan AIO and LX fans with iCUE, which is the build I'm going to go for. And the self uninstalling thing is still an issue. But there's really no other better option. All I can do is maybe pay a bit extra for a geek squad protection through Best Buy and hope that if anything happens that I can just go to the local branch and have it immediately replaced.

So yeah, just wanted you to know that there's really no perfect solution out there.. and I'm back to Corsair

r/pcmasterrace on Reddit: RANT: Why the hell do I need to download Corsair's 2.2gb iCUE software in order to stop my brand new, hundred dollar mouse from lighting up like a Christmas tree?
March 3, 2022 -

I bought a new Corsair mouse after several years of good luck with their products, but this new mouse is driving me nuts; after a few days the RGB's began to flash like crazy and the back/forward buttons stopped working. Taking the internet's advice I installed Corsair's icue software (which was advertised as being about 800Mb but actually showed up as about 2.2 gigs when installed), and when reading through the EULA of course I found a large section detailing all of the data that the program hoovers.

How the hell can Corsair justify selling a mouse at premium pricing, then use flashing rgb's and lack of button functionality to force the consumer to install their rgb program (or suffer through seizure-induing rainbow vomit) which then sells your goddam data?!

That's it. I'm through. Corsair used to be a company I respected, used to build whole rigs with their parts. No more.
