Super bad framerates with a 100% GPU use spike. Can't figure out what's wrong, as temperatures are pretty low.

Super bad framerates with a 100% GPU use spike. Can't figure out what's wrong, as temperatures are pretty low.
Okay, so I've been trying to find out why this is happening for about a week, my machine is a Thinkpad P53 workstation, with a 6-core 12-thread i7-9850H and a Quadro RTX3000 GPU. I know this sub is mainly geared toward desktops, but I didn't know where else to ask, as I believe if anyone would have great troubleshooting skills in this topic, it will be you guys.

So, I've had this machine for almost a year now, no issues until about a week ago. I have 64GB of RAM and 2TB of nvme SSD storage as well, so I doubt there's an issue there. I started playing a pretty non demanding game, Monster Hunter World, and purposefully set it to 1080p and medium settings, whereas I can run it at 4k 60fps no problem with high settings.

The issue happens sometimes after 5 minutes of playing, and sometimes after 30 minutes of playing, it's pretty random, but what will happen is that fps will drop from a solid 60fps to a stuttery 15-20 fps, the important aspect of this is that the exact moment it happens, the GPU usage jumps from around 50% to a full 100% and stays there, not sure what's happening. I know that "100% GPU usage is good" but this case is different. The machine is powerful enough, as I'm pulling 60fps with the highest settings with 50-60% usage, but it only jumps to 100 the exact moment the performance drop occurs.

I downloaded MSI Afterburner and RivaTuner to see it in action and got this screenshot:

Temps are fine, they rarely go above 80-85C ever, as I've repasted the machine.

I took this a few secs after the performance drop, I notice that there's a temp and power throttle, the power throttle is usually there most of the time, and doesn't exactly affect performance, however the temperature throttling is what I find puzzling, as you can see the temps are fine, and stay there pretty much with every game, since it started happening about a week back, I decided to repaste the machine, and even though it helped keep temps much lower than before, it still didn't solve the issue.

After reading several threads here, I couldn't find any which were analogous to "High GPU usage, FPS bad", but I did read about several people that found out they had a bitcoin miner malware in their machine which spiked GPU usage. I decided to completely reinstall Windows in order to get rid of that probability, I made a bootable usb drive with the Windows Install tool and completely wiped all of the partitions before reinstall. The issue remained, so I could count out bitcoin malware, or Lenovo drivers, since the clean install came without any Lenovo bloatware, and also driver issues, so I just upgraded all my drivers back to the newest ones, now here I am, desperate to find out why this is happening, begging for help in pcmasterrace.

Is there any other benchmarks/tests I can run to diagnose the issue? I bought 3dMark, PCMark, and VRMark to benchmark my machine, and ran the time spy benchmark without issues, but only a couple of times, maybe not enough to have it show up.

Lastly, I have the machine plugged in, and on 'Best Performance' mode, which according to the machine, should provide the best cooling instead of caring about being quiet.

EDIT:
I'll also add, that the issues go away after a machine reboot, and sometimes when changing the performance slider from 'Best Performance' to something else and then back. At this point I think it might be driver or BIOS version related, so perhaps waiting might be the key.

Zeus/Gaw ASIC Setup Guide for Linux/Raspberry Pi

So I recently I became quite interested in mining and cyptocurrencies in general. So interested in fact that I bit the bullet and decided to buy myself a GAW Fury.
I then spent some time doing research on how to set up a GAW or Zeus ASIC on Linux, in particular on a Raspberry Pi, and have found most guides to be awful. The reason they are so bad IMHO is that they assume quite a bit of prior knowledge, either with Linux or mining, and give very little instructions. So I have tried to put together a guide that requires very little prior knowledge.
It is my aim that anyone could get their shiny new asic up and mining in no time using this guide. Anyway, I present...

The Complete Noobs Guide to Setting Up a Zeus or Gaw ASIC on Debian/Ubuntu/Raspberry Pi

Resources

About Cyrptocurrencies and Their Jargon

If you are new to cryptocurrencies and how they work I suggest taking a look at this series of KhanAcademy videos. They are for Bitcoin but the theory is the same. I found them very helpful when it came to understanding what mining actually does and the mechanics of cyrptocurrencies.
Also take a look at sircamm22 his info found here, is great and breaks down a large number of concepts. I slightly disagree with no. 21 regarding preordering. Just exercise common sense.

Linux

If you are new to Linux you could follow along by simply typing in the commands. However I highly recommend taking the time to learn what you are doing. This course is a great place to start.

Computer Setup

By the end of this section you will have your device turned on, fully setup and connected to the internet with.
Note: Commands to be typed into the command line will be displayed like this:
echo Hello World

Desktop/Laptop

For laptops and desktops already running Ubuntu or Debian I will assume you have setup your internet setup as part of the installation.
If not: There are plenty of guides out there and the installation/setup process is very easy. A good place to start for Ubuntu is here.
Now open up a terminal window. Ctrl + alt + t on a standard Ubuntu installation.
If you plan on using this PC without a monitor I would suggest installing an SSH Server.
These commands will be discussed later on in the guide.
sudo apt-get -y install openssh-server
sudo service openssh-server start

Raspberry Pi

The Raspberry Pi Foundation has put together a great guide in PDF format.
Use NOOBS it will save you a lot of trouble. NB: Some SD cards don't support NOOBs but will work fine if the image is put on using a different method.
Here is a great guide for setting up the Raspberry Pi SD card from Elinux.org. In fact it's a great place to start for anything RPi related. Raspberry Pi hub at Elinux.
Once the SD card is setup you will need to insert it into the Raspberry Pi and boot. Install Raspbian from the NOOBs menu and wait.
Follow this guide by Adafruit for first time setup. You will need to enable SSH Server.
I suggest not starting the desktop on boot. It can be easily run from the command line by typing startx.
Follow this guide by Adafruit to setup your network. Found here. No need to do this if you set up previously in the first time config.
We will also at this point want to setup ssh. Again I will point you to an Adafruit guide.
Once done exit back to a standard command line interface. This can be done in LXDE by using the power off menu located in the bottom right corner.

Miner Setup

Installing BFGMiner

If you want to the Raspberry Pi or PC without a monitor go ahead and SSH into your device.
So now you should be staring at a command line interface whether on the device with a monitor or via SSH.
First things first lets make sure we are all up to date. This will update our package list from the repositories and upgrade them to the newest version. "-y" Will simply say yes to any prompts.
sudo apt-get update && sudo apt-get -y upgrade
We are going to need to install some useful tools. Git-core is how we will clone and download BFGMiner from GitHub and Screen allows multiple command line instances and means if we exit out of ssh session or quit Terminal on Ubuntu, BFGMiner will continue to run.
sudo apt-get install git-core screen
We also need to download some other tools/dependencies to ensure that BFGMiner will compile successfully.
sudo apt-get -y install build-essential autoconf automake libtool pkg-config libcurl4-gnutls-dev libjansson-dev uthash-dev libncursesw5-dev libudev-dev libusb-1.0-0-dev libevent-dev libmicrohttpd-dev libc-bin
Ok now change into your home directory.
cd ~
And clone BFGMiner by Darkwinde.
git clone https://github.com/Darkwinde/bfgminer.git
Once the download has completed move into the bfgminer directory.
cd bfgminer
The following steps may take a while.
Now run autogen.sh
sudo ./autogen.sh
You will need to make the configure script execuitable.
sudo chmod +x ./configure
Now configure bfgminer
sudo ./configure CFLAGS="-O3" --enable-scrypt
Now lets make!
sudo make
Install BFGMiner
sudo make install
One more thing...
sudo ldconfig

Running BFGMiner

If you haven't already plug in your ASIC.
Just confirm your system is recognising the ASIC.
lsusb
Its output should look similar to this (no need to type this in):
Bus 001 Device 005: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light
Yep there it is our ASIC listed as device 005. There is no need to install any drivers, unlike in windows, as they come in the kernel.
Now lets actually start BFGMiner.
You will want to start a screen session to ensure BFGMiner doesn't quite when you exit.
"-S" is the option for starting a new screen session. You can replace "miner" with anything you like.
screen -S miner
Now you can run the commands below.
Here is a sample of what you should type. You will need to replace somethings with your own values.
sudo bfgminer --scrypt -o stratum+tcp://URL:PORT -u USERNAME -p PASSWORD --zeus-cc CHIPCOUNT --zeus-clk 328 -S zeus:/dev/ttyUSB0
Where:
URL:PORT is the address and port of the pool you wih to use. Now I won't suggest a pool. I will leave that decision up to you. If you do wish to mine DOGE take a look at this site for a list of pools and comparisons.
USERNAME this is the username you use on the pool. Every pool is different. Check your pool's website for details. PASSWORD same as above. Specific to your pool, not every pool requires one.
CHIPCOUNT this is specific to which ASIC you are using.
For GAWMiner ASIC's:
  • War Machine: 256
  • Falcon: 128
  • Black Widow: 64
  • Fury: 6
For ZeusMiner ASIC's:
  • Blizzard: 6
  • Cyclone: 96
  • Hurricane X2: 48
  • Hurricane X3: 64
  • Thunder X2: 96
  • Thunder X3: 128
Now to make sure you don't stop mining when you exit ssh or terminal. Press:
ctrl + a + d
To come back to the BFGMiner screen simply run:
screen -r miner
You're done!!

Start on Boot

First off you will want to make sure you have BFGMiner running correctly. Ensure you have the miners set up properly and your pool correctly configured.
Start a BFGMiner instance, detailed above.
Once the instance has started and you are happy with how everything is working press "s" on your keyboard to enter the settings menu.
Now press the "w" key. Don't press enter. We want to specify where our config will go. Type:
/home/USERNAME/bfgminer.conf
Substitute USERNAME for your user. On a standard RPI install its pi. On ubuntu it's what you set during the instillation.
Now press the enter key to return back to the main BFGMiner screen. Press "q" on your keyboard to exit BFGMiner. You should now be back in the command line.
Now we want to edit a file called rc.local. Any commands in this file will be executed on boot.
sudo nano /etc/rc.local
Depending on your system this file may already contain some commands. Be careful not to delete them.
After the last command and before "exit 0" type the following on one line:
sudo -u USERNAME screen -d -m sudo bfgminer --config /home/USERNAME/bfgminer.conf
Where USERNAME = your username
Hit ctrl + x then y to save and exit nano.
The above command will create a new screen session and run bfgminer using the config we created earlier. All while as our username so that we can easily reattach.
Lets reboot to ensure it is working correctly:
sudo reboot
Once rebooted and logged in, show all running screen sessions:
screen -ls
Reattach to the session. You only need to use the numbers before the first dot.
e.g Mine looks like: 2480..hostname (13/07/14 12:02:09) (Detached). So I type:
screen -r 2480
Verify everything worked as expected. Then ctrl + a + d to exit.
You have now setup BFGMiner to restart on reboot.

Power Failure

If you are using a Raspberry Pi and it loses power it will automatically reboot on receiving power again.
For standard desktop PCs there is an option in some BIOS/UEFI to turn the computer on when it receives power. Consult your motherboard's manual and manufacturer's website.

Sources

Here is where I got my info from.
And of course /dogemining

Wrap Up

Congrats you've done it. You have managed to successfully get your shiny new asic mining away.
I do plan to make another guide detailing how to setup and use StarMiner a ready to go RPi mining distro.
So I hope this is helpful for you guys. I have seen lots of posts asking the exact same questions again and again and I have tried to answer these as best I can. I am still learning about this stuff so if there is something I have missed or a mistake I have made please tell me.
Anyway good luck. And I'll see you at the moon.
Cheers Frogsiedoodle
Edit 1: Layout and formatting.
Edit 2: Added instructions for screen which I initially forgot.
Edit 3: Removed 1 unneeded dependency
Edit 4: Added section on start on reboot and power failure.

Trouble getting into BIOS/Install Windows 7 [New Computer][MOTHERBOARD]

Hey! I'm having some difficulties setting up a new rig. It boots up fine, but when I get to the "choose language" page of the Windows 7 installation the rig either freezes or doesn't recognize the mouse or keyboard.
I've read that some problems might arise with legacy USB devices, and so I've attempted to get to the BIOS and resolve the issue. When I press "delete" on boot, the screen goes dark and has a singular white dot. I have gotten to the BIOS once during the process, but this was before I thought to edit the USB setting. Any help would be much appreciated. Thanks!
EDIT: I do get the one short beep during startup from the onboard speaker.
