Motherboards with AMD processors / Gigabyte x399 Aorus Extreme PCI express lanes issues

« Last post by SilverSurfer on October 18, 2018, 01:33:48 pm »

Just wondering if anybody else having issues on the latest F4, and previous BIOS, with USB PCI express cards on any PCI express slot.
 I'm getting all USB PCI express cards not installing all the host controllers correctly with the 2 bought
"StarTech.com 4 Port PCI  PCI-E USB 2.0 Card"
, one of the 4 host controllers don't install plus the unknown USB device area below, or
"StarTech.com 4 Port PCI Express (PCIe) SuperSpeed USB 3.0 Card Adapter w/ 2 Dedicated 5Gbps Channels - UASP - SATA / LP4 Power"
giving power surge when any USB device is inserted. I then changed to another brand,
"SilverStone SST-ECU01 - SuperSpeed 2x internal USB 3.0 PCI-E Express Card Gen 2.0 x2, 10Gbpy",
 and got the "unknown USB device, USB descriptor failed" error.
With all of these errors other than the first USB 2.0 card the device drivers didn't show an error in device manager and so had successfully installed either with the Windows 10 drivers or with the manufacturers recommended drivers.

I have ordered a replacement gigabyte motherboard, arrives on Saturday, but I just thought I'd check beforehand to see if others are having a problem with this particular board. I moved to AMD because I was reassured that with AMD CPU and motherboard chipsets the USB has a better USB bandwidth implementation than Intel motherboards but so far that has not been the case. I have a lot of USB bandwidth hungry devices as I run on this enthusiast motherboard a racing chair motion simulator with my Fanatec wheel and pedals with a total of 13 USB devices.

I've got a MSI X 399 Meg creation on order if I need to jump ship but really I'm a gigabyte fan boy and their supporters been very good so far. The MSI does have more phases and more lanes if I'm not mistaken so that might help my situation. I'm still hoping that I don't have to go to a full workstation motherboard to solve this USB issue which I think will become more problematic as I haven't even included my Samsung Odyssey VR headset which I know is a definite USB hog, but I'll faced that problem once I solve this initial PCI express card issue.

Motherboards with Intel processors / Re: Z270x Gaming 7 ,Win10 freezes at restart Error Code 8

« Last post by shadowsports on October 17, 2018, 02:00:11 pm »

When i press restart the PC freezes for one sec. then windows shuts down but the pc does not boot with error code 8 so i have to clear the cmos then configure it again in order to boot normally, this happends randomly not at every reboot.
I dont know what to do to fix this problem.

Greetings,
There is no diagnostic or error code documented for "8".

Please provide your full system specs

Did the system restart behavior ever work as expected?

Has any new hardware been added recently?

Was this a fresh install of windows 10, or did you migrate the install from another system?

Have you updated the BIOS?

And..  are you using any utilities (software) with hardware profiles for fans, GPU, etc?

Graphic cards / Windforce OC RTX cores/Ops

Does anyone know how many RTX cores/Ops the GV-N2080WF3OC-8GC has?

The product's specification page does not state it.

Motherboards with Intel processors / Re: Interference on line out going to hifi

« Last post by ahardy42 on October 14, 2018, 10:54:54 pm »

I read up on impedance and SPDIF and hardware and came across stuff on ground loops  which accurately describes  the symptoms I've got. So it seems I could go for SPDIF if I purchase on of these adaptors you mention. I'm slightly worried about SPDIF though as some of the links describe it as problematc and it sounds like it might butcher some of the low volume classical stuff I listen to.

Maybe I'm better off trying to hunt down the ground loop issue, but a couple of things worry me about that - firstly there was no improvement when I grounded the external chassis to earth - and secondly my headphones don't appear to be effected by the poor noise quality when plugged into the same line out.

I used this:

I had to move one of the PIN outs to match the header.  I used a toothpick. 

Your device might work too, but whenever you introduce a powered device, there is a risk of interference.  I think the drivers and a lack of isolation are very possible causes of the sounds you are hearing.  Have you experimented with others? 

Google impendence.  It is similar to resistance, with the addition of phase.

Hi,
thanks for the reply.

I'm taking the output from the green line out jack and feeding it into the amplifier AV stereo input.

I'm still learning about all the tech behind digital sound production - with my last PC, I didn't have to know anything since it worked flawlessly as soon as I plugged it in, nice for me back then.

So if I used the SPDIF Out, does that mean I've have to get a sound card to pipe it through to the outside?

You mean something like this: https://www.amazon.co.uk/Ex-Pro%C2%AE-Analogue-Digital-Converter-TOSlink/dp/B009K55TJI/ref=sr_1_44?s=electronics&ie=UTF8&qid=1536917553&sr=1-44&keywords=RCA+to+spdif

Doesn't that mean I'm wasting the onboard sound card?

You mention cable quality - but it's not really a continuous noise that would suggest that, I talked to people with experience in this area and they said it's noise coming from the CPU power itself on and off, because the noise varies with what I'm doing on the PC.

Impedance - what is that? Can I measure it or fix it?

The driver version or settings might be the cause. I'm using Ubuntu Linux, the installation detected the sound card and installed the driver automatically.

I asked on AskUbuntu first, and got the  response that this was some sort of ground loop or motherboard defect. I only got the one reply, so it may have been one of  the sound driver developers  themselves who wasn't prepared to admit the possibility of their own efforts being error-prone.  Check here if you want:

https://askubuntu.com/questions/1071245/ubuntu-installation-audio-crackling-hissing-related-to-mouse-keyboard-and-gui

Hardware incompatibility is the last on your list - which bits of hardware could be incompatible? I'm looking at the idea  of buying additional hardware e.g. a DAC or stuff like this:

https://jcat.eu/product/usb-card-femto/

which I don't want to splash out for without really understanding  whether I need to or not.

Greetings,
Not a whole bunch of information for us to go on.  So you are using analog out to what type of input?

You might be better off using SPDIF out (header on the board).

Possible causes:
Quality of cable
impendence
Driver version
Driver settings
Hardware incompatibility

Motherboards with Intel processors / Re: Mobo Z390 and Corsair v 4.31

« Last post by shadowsports on October 10, 2018, 02:58:12 pm »

In the description of the disc Aortus Z390 Master writes that the compatible memory Corsair is eg. CMK32GX4M4E4133C19R ver 4.31 - How to recognize which memory is ver. 4.31? Where to look for such signs? And what's the deal with this version at all?

Greetings,
It is indeed just that, a hardware version number.  It denotes a specific version of hardware when the memory was made.  It could be several things.  The memory chips themselves or the manufacturing process used for the PCB. etc.  Most likely its the chips though. 

Where you'll see this identification.  On the box (label or sticker) or on the module itself (again label or sticker).  Most if not all resellers will not include this information unfortunately.  As long as you are buying from a reputable vendor who moves (rotates) stock regularly, you'll get this version or later without having to worry.

Motherboards with Intel processors / Interference on line out going to hifi

I've got a Z370N Wifi and I want to use it to deliver digital music to a high-end hifi amplifier.

The sound that it delivers has a low volume hissing and cracking type of interference that ruins sound quality.

This is a replacement system for an old ASUS motherboard-based system, which produces flawless sound.

What can I do to improve the situation?

I've already tried a USB DAC which didn't help much. I've also tried grounding the PC case, which also only makes a limited difference.

Thanks!
