BSODs caused by USB hub/cooler P-7811fx

Ive found that the NZXT cryo can cause BSODS on boot and sometimes they seem to be purely random (ie idle on the desktop etc). Event viewer shows some type of bus error.

Now I know USB hubs are known to cause these types of trouble sometimes. What is the most likely cause of this?

Bad NZXT drivers?
the PC hardware?
Motherboard drivers?
The NZXT hardware?

I do not seem to have this trouble with other USB devices. So I am assuming its a bad NZXT driver or some sort of conflict with the mb drivers...though why arent the other users of this cooler on the forum getting this? Hmm

I am running a clean install of vista 64 with all stock drivers besides video.

 

A corrected hardware error occurred.

Error Source: Corrected Machine Check

Error Type: Bus/Interconnect Error

Processor ID Valid: Yes
Processor ID: 0x0
Bank Number: 5
Transaction Type: N/A
Processor Participation: Generic
Request Type: Generic Error
Memory/Io: Generic
Memory Hierarchy Level: Generic
Timeout: No

That is the error I'm pulling from event viewer.

 

Is there another 7811FX user of the cryo on these forums? I know that there are some people with the 6860FX that use the cryo and it works fine.

 

easy fix. don't connect it to usb, get a generic 5v usb charger.

 

Yeah, this may works fine

 

Thats not a bad idea even for people who are not getting BSOD because many reviews I read about the Cryo stated that a lot of notebook's usb ports dont have the power to be able to run the cryo at full speed.

 

Yeah, but you cant make use of the hub without using USB. There are easy fixes for that too...like finding a hub that works. Seems kinda silly though. I was going to find some other way to power it anyhow...but I wouldnt mind having those usb ports.

 

Mine works fine.. no issues. I leave it hooked up constantly. Your USB-Power should be hooked into the right side USB, and your USB-USB should be hooked into one of the two left side ports. This should be enough power to run the fans constantly.

If you hook it up any other way, or without either of the two cables the fans won't turn.

The NXZT has no drivers really.. just the generic USB hub. It sounds more like it's drawing to much power on bootup causing a BSOD, kinda like if you undervolt yer CPU to far.

But that is pure speculation on my part.

(all hardware is different, your mileage may vary.)

 

Quick question on the P-7811 USB ports...are all of them powered USB 2.0 ports? I noticed one on the left doesnt seem to be, Defect maybe?

 

I'm not sure what they are supposed to be by design, I'll tell you this much though. They don't all seem to be able to kick out the same power because the only configuration that would work is the one I stated above.

It might be something like having both plugged in on the left was splitting the power to far. Not really sure.

 

Im starting to wonder if the AC + USB + Laser mouse + PDA combo is whats causing the BSOD, sometimes I have an enclosure hooked up also. It was worrysome though because I ran this setup fine for days...than one day I went to start lappy up and it would not do so for like four attempts. When I finally got logged in...everything was bonkers. The works...CD ROM drive, ethernet adapter, everything. Once I unplugged the cyro...everything magically work. Then over the next few days the random BSODS started...most happening during the startup process. The NZXT really pissed me off because I was convinced I had serious mb issues haha...technology is awesome when it works yeah?

Too much stuff hooked up maybe. I dont think it is a defect with my machine because obviously I use a lot of USB devices and none of them cause problems.

 

NOW the truth comes out...

I think your overtaxing the power from the laptop by overtaxing the USB hub.

Get an external wall power adapter for the NXZT and you should be fine.

Thats my educated guess anyway, but I've been wrong before.

 

I just got my Cryo and am having the same issues...

When I first hooked it up, I ran both the DC and USB cables to the two left side USB ports and my 7811 wouldn't even boot... I only tried it twice, but that is enough to know that something is wrong.

I then disconnected them and everything booted up fine. Once I was into XP I tried plugging in the cable and I get this...



When I plug the DC cable into the right side port, the fans start right up but it still throws the error. When I connect the USB to USB it throws the error briefly and then goes away once the fans speed up.

When I do the same under Vista I get the exact same results, but no errors are thrown. This really disappoints me because other than this issue I am really impressed with this thing.

Also there is nothing else connected when I am doing this.

 

I get BSoDs from my mouse drivers. . . I uninstalled them and no I don't get any more BSoDs.

 

i posted this in another thread:

 

i have the zalman nc-1000 connected even when on battery never had any issues. and true the hdd temps are the one that benefit the most.
