AX860i Corsair Link USB Dongle Not Working?

Hi!

 

I've recently been having a few infrequent and intermittent PC freezes whilst gaming, so I've been running HWInfo to see if anything stands out. Clutching at straws, I've noticed that the 5v rail is dropping to 4.52v and the 3.3v rail is dropping to 3.056v.

 

I know that software monitoring of PSU voltages is unreliable at best, so I decided to try using my USB Link Dongle as I've read that that gives more accurate voltages. I haven't been using it because I could never get it to work...but it still doesn't work properly.

 

If I look in device manager the Corsair USBXp Driver is under hidden devices and showing as disconnected (Code 45). If I disconnect the USB header and plug it back in again, I hear the connect sound and then an immediate disconnect sound. The light on the dongle flashes green for less than a second. The PSU doesn't show in iCUE.

 

I did manage to get the PSU to show in iCUE once by uninstalling the USBXp driver and restarting the PC. The device in device manager was still showing as disconnected but it did appear in iCUE. However, once I restarted the PC again, it disappeared and I can't get it back again by following the same process.

 

I've tried using both USB ports on my Commander Pro...I haven't yet tried plugging it directly into the motherboard, however, as that would require some rewiring.

 

Am I doing something wrong?

 

Any help would be much appreciated!

Thanks!

 

I put in a support request a week ago but still haven't heard anything back yet. #2001268008

Thank you very much!

 

It seems to be working fine and the voltages seem stable however I’m still convinced my problem lies somewhere in the power delivery.

 

My freezes initially turned into CRITICAL_PROCESS_DIED BSODs, which has now turned into WHEA_UNCORRECTABLE_ERROR BSODs.

 

I ran OCCT GPU stress test for two 12 hour periods without a crash. I then ran OCCT CPU stress test (small data sets, AVX2) for 12 hours, again without a crash. So individually the components seem to be fine.

 

If, however, I run OCCT Power stress test (which loads both CPU and GPU) it BSODs. Two days ago it crashed in 2 hours, last night it crashed inside 2 minutes. Same happens if I combine Furmark and Prime95 or play games (although it doesn’t always happen so quickly)

 

Temperatures for the CPU and GPU are well below maximum and everything has been reverted to stock so I have no overclock in place. I’ve tested the memory with MemTest86 for 4+4 passes multiple times, RAM Test for 10 hours, HCI Memtest to 1000% so I’m fairly sure it’s not that. I even got my NVMe replaced.

If i'm not mistaken, the +5V should be between 4.75 and 5.25V, the 3.3 should be between 3.135 and.. 3.465v

 

Your GPU and CPU run from the 12V rail so they should be unaffected, but something else maybe on the mobo, using those secondary voltages may be crashing you..

If you have a bunch of RGB stuff, like fans, maybe turn the lightings off to ease the load on the 5V rail.

 

If you have a multimeter, you can check the 5 and 12V values on a molex connector pretty safely just to be sure.

Thanks!

 

Unfortunately I don't have any RGB fans, only LED ones which aren't controllable. All connected to a Commander Pro.

 

The Corsair Link Dongle is reporting a steady 12v, 5v and 3.3v under all loads.

 

The motherboard, at idle, is reporting pretty close to these values. However, under full load the 3.3v is dropping to 2.94v and the 5v is dropping to 4.6v. So not sure if that points to a motherboard problem.

Try Corsair Link and see if it recognizes your PSU properly

Thanks!

ayyy.. if all secondary rails dip like that, maybe the primary side got wonky.. like bank caps getting tired..

Is this PSU old? We need an old priest and a young p.. guru i mean..:D:

If you have BSODs and reboots, it's clearly not a iCUE voltage readout issue. They likely really dip that low.

Lol! This PSU is actually a replacement as my first AX860i outright died. Got it 3 years ago I think, which was how long my 1st one lasted.

 

iCue is reporting a steady 5v, 3.3v and 12v rock solid so that’s why I’m thinking the PSU is fine, unless it’s having dips I can’t see or aren’t being registered or if something else is happening not involving voltages.

 

It’s my motherboard sensors that are reporting those large dips under load, but I’ve read not to believe those so I’m not sure.

 

I did another OCCT PSU test this morning. Took 2.5 hours to crash...WHEA_UNCORRECTABLE_ERROR. Been running Prime95 Small FFTs AVX this afternoon. Been going for 5 hours so far which gives further weight to the assumption that individually the components are working fine.

 

I’m not getting any crash dumps either so I literally have no starting point!

 

:(:

Thanks, that’s my assumption at the moment!

 

I‘ll run a couple more stress tests overnight and I think I’ll ping ASUS...see if I can get them to have a look at it.

I may have had a small breakthrough...not sure if it’s still going to crash but...I’ve fixed the motherboard voltage drops under full load by removing the PSU extension cables I’ve been using for about 6-7 years. I’m guessing they’d gone bad. Edited July 2, 2020 by PilotGW

They were old BitFenix Alchemy extension cables from 2013 so not too sure...lesson learned. I’ll buy proper Corsair braided cables next time I upgrade.

 

Thanks for your help!

Unless those extensions use 16g wire, I would never use them.

 

Ohm's law, you know.

 

 

I use 14 gauge power cables which can handle loads safely. Power bars sold here are required to be 14 gauge but some 2-pin extension cords may be lighter gauge.
