Phanteks NEON RGB Strips ?

[Glenn67]

Hello all. I am new here and this is my first post. I can't seem to find another 'section' to post this little 'adventure'!

Motherboard is a MSI MPG Z390 Gaming Pro carbon (MS-7B17)
Bios = E7B17IMS.1A0 (08-13-2020)
Latest windows 64 version (2004)

I was previously running a 'normal' 12 volt RGB strip connected to the JRGB1 header with no problems whatsoever.

Decided to buy 2 Phanteks M1 Digital RGB LED strips (from Overclockers UK).

At first, I daisy-chained them and connected them to the 5V JRAINBOW1 header. Powered up the PC, started MysticLight (from within DragonCentre) - But, the M1's were not being detected. They are not even lighting up at all - not even a little flash when turning on the PC. So I powered down the PC then connected just 1 at a time but neither worked. Tried connecting the supplied adapter/extension lead at the other end - still nothing. Uninstalled Dragon Centre (because I never use it for anything) and then installed Mysic Light (V3.0) on its own. Still Nothing.

Have read countless, unhelpful, posts via a Google search. Have re-booted PC countless times. Have even delved into the BIOS to see if something might be amiss, but can't see anything.

It seems unlikely that I would have been unlucky enough to buy 2 dead and useless LED Strips. Or maybe the JRAINBOW1 header is just dead (how - I have never used it before!?). That seems to be the only 3 pin 5V header available on the board, so I can't try another one.

On advice from MSI Tech Team, disconnected the 24 pin power and removed motherboard battery for at least 5 minutes. It made no difference.

Managed to borrow a multimeter and discovered that the JRAINBOW header is pumping out 5.05 volts, so that seems to be OK.

Am I the unluckiest person on the planet and actually bought 2 dead and useless strips of plastic???
I suppose one must consider the possibility that Phanteks have made a mistake stating that the Neon Strips are compaible with MSI Mystic Light - however I think that would be very unlikely

Now I am completely out of ideas. Has anyone come accross this before / found any solutions / have ANY ideas?

Have a good day everyone and thanks for any replies,
Glenn


EDIT: THE PHANTEKS NEON DIGITAL RGB LED STRIPS ARE OBVIOUSLY NOT COMPATABLE - AS STATED BY PHANTEKS - WITH MSI MOTHERBOARDS / MYSTIC LIGHT (AT LEAST NOT MINE). THEY WORK PERFECTLY WELL WHEN USING PHANTEKS OWN DIGITAL RGB CONTROLLER !! TAKE THAT AS YOU WILL.

A quick post in case anyone else is interested:

So for me on a MSI B550M Mortar board this just works. This board has the nuvoton NCT6687-R fan/rgb controller on it (the OpenRGB wiki has all the gory details including how easy it is to brick). The Z390 apparently has a NCT6797 but I don't know what if any the differences are.

Mystic light software doesn't "know" if there is a strip there or not, So there isn't a obvious way to tell (without involving a oscilloscope on the data line) if the strip is properly attached or exactly what the issue is.

There might be a timing issue (see https://cpldcpu.wordpress.com/2014/06/16/timing-of-ws2812-clones-pd9823/) depending on exactly what sort of WS2812 clone is in the strip.

Sorry Glenn67, but all I can say is "Works for me" which isn't very helpful.

They work on my B550 Tomahawk as well:

(Yes I know I need to do something about that cooler...)

The cooler is fine, I ended up going with a AIO for my build as the noctua DH15 I have been using obscures so much of the interior.

My biggest gripe is the stupid dual plug PCIE cables PSU manufacturers supply by default.

Solved this by going with a beefy Corsar RM1000x and their braided PSU cable kit which has all of the inline capacitors in the cables (and the PCIE only has one plug per cable) but even then they only supply one cable comb per cable....

It would also help if the neon strips had longer cables as I couldn't tuck it behind the motherboard without the plug & sockets fouling I ended up clipping them off and soldering them instead.

Anyway next job is sorting out my cable management at the rear which currently is non-existant and a candidate for a what not to do article.
