New rig crashing as soon as I try to 5-box

Hey guys, just got a brand new computer and was pretty excited to try 5-boxing WoW again, but unfortunately, as soon as I pull up 5 windows (Using ISBoxer), my system crashes. Before I lose everything I can quickly see a message about my "graphics driver has stopped responding", something to that effect. My system spec is as follows:

Processor: Core i7-6700 @ 4.00 GHz
RAM: 64 GB
OS: Windows 10
Graphics Card: Radeon R9 380, 4GB GDDR5

All drivers are up-to-date. I would think that this system would kick the shit out of any WoW multiboxing I could throw at it, since it blows away my last PC and I was boxing just fine on that one. There's got to be some sort of issue/setting that I'm missing.

Also, I was 6-boxing EverQuest just fine on this new rig last week.

Also, no add-ons for any character are active except ISBoxer

Update: I logged into the individual characters through ISBoxer and lowered their graphics settings. Being a fresh WoW install, they defaulted each window to max graphical settings for everything. Seems to be working now.

---------------

Maybe not. Took the team into BWD and it crashed again

So I went in and lowered EVERY window's graphics to the lowest possible setting, and as soon as I start taking the elevator down in Blackwing Descent, I still crash. I'm stumped at this point. This makes no sense to me.

A few things...

First, the ISBoxer Wiki has a page for tweaking your framerate, and monitoring your hardware, which I suggest you check out. I also recommend using another program to watch your GPU's VRAM usage (e.g. GPU-Z) since Hardware Monitor doesn't do that (unless it does now).

Second, is the game fully installed? If you have a partial install where the game client is trying to stream the data to your machine then it's likely going to cause problems when attempting to stream the same data to multiple game clients running from the same machine/drive/folder. Also, have you tried to repair the install in case it's, for some reason, corrupt?

Third, I understand you are giving updates to your situation, but I have to ask that you don't keep replying to yourself in a very short period of time because it creates a thread that is difficult to read and reply to. I've merged everything into your original post, but if you are going to add to your own thread several times in a short period of time, then I ask that you just edit the latest post which reflects your pending situation, thanks. (Obviously from here you can feel free to start replying again :))

I can't box on windows 10. I downgraded to 8.1 months ago.

I had the same issue - it is your graphics card.. I have the very same one bought recently!

Roll the driver back one.. fixed it all for me!

If your issue isn't fixed by now, is your GPU overclocked? This can also be caused by an unstable overclock on your GPU. Though i think you'd probably of already known that if that was what it was. Another thing is it could be getting entirely too hot and had hardware failure due to that. Its also worth checking to see if your GPU is fully seated into the motherboard. That may sound silly but i've encountered it before. I always use NVidia GPU's in my builds so i'm not sure if you have this but if you have a control panel for your GPU's driver settings, check that and see if anything looks odd. Although thats probably unlikely unless you made changes yourself. Using an older driver as suggested above may work for you as well, as sometimes AMD and Nvidia just release buggy drivers and you have to wait for the next release for them to fix it. Its rare to hear about a GPU driver crashing just due to stress unless its heat related... The last thing is it could just be hardware failure. HWMonitor is a program that can monitor the temperatures of your hardware. While using that, run a stress test and see what happens. Heaven Benchmark 4.0 is a good one. If your temps go above 85c, that is likely the culprit. If not, it doesn't necessarily mean bad hardware. I'd do some googling on it if it hasn't been fixed yet.

If your entire system crashes after the driver stops working it is likely either the GPU you got is damaged or is getting too hot and throttling isn't keeping it cool enough, so the system shuts down to protect itself. Rare with GPU's though, they usually just throttle. HWmonitor will tell you the GPU fan speeds aswell to make sure those are running. Thats all i got
