Hardware issues multiboxing 16 clients with 5960X, 980 x3 sli

[lovesbunnys]

I'm having issues with my rig pulling off 16 clients of WOW. Trying to get to the bottom of what I'm doing wrong. Wow graphics settings are on low. I get intermittent low fps. My isBoxer profile is default, round robin balancing. I've seen MiRai get 20-30 clients to work on his rig, I'm sure I'm missing something. Any help in the right direction will be appreciated.

My rig:
i7-5960x
Rampage V Extreme
Evga GTX 980 SC x3 with SLI Bridge
32gb Vengeance LPX DDR4
Samsung SSD 850 EVO

Looking at your pictures there, your CPU's have topped out at some point. Is that from during gameplay?

I recommend not using Round-Robin balancing on the CPU, because if a core gets busy with other stuff, e.g. Network processing, swapping your desktop background, or some other boring process, then any games assigned to those cores will suffer for the duration. On the odd occasion Round-Robin may be needed but fairly rarely - Windows is pretty good at managing CPU allocation.

My recommendation is to go to the Wizards menu, select CPU Strategy Wizard, and give it "all instances use all CPU cores". I also like to set Master Slot = <NO SLOT>


With regards to the graphics. They are showing ~3GB memory usage just at the character select screen. What about during gameplay?
Also, IIRC, in the video with MiRai running loads of toons around he said that they were not SLI'd at the time due to lack of VRAM this causes. Running 30+ toons in 3GB would be limiting (MiRai had 780TI's I believe)

When I configure two graphics cards in SLI mode, do the graphics cards work together to create double the memory size?No. In SLI mode, each graphics card uses its own frame buffer memory to render a 3D application. The operating system will report a graphics card frame buffer memory size that is found on a single graphics board.

I 15-box with a less-powerful computer than that and I have zero issues.

As Bob said, instead of round-robin you should have all instances use all cores. I always get better performance like that.

Thank you! Changing the master slot to no slot and CPU strat to select all CPUs with every window did the trick. Now I'm seeing 60 fps in main window with no throttling. I am running wow video settings on low.

Are there other helpful tips like this one that will get more performance?

This page on the ISBoxer Wiki covers a handful of general things.

I have all my alts render at 50%. This significantly improved my performance, but I imagine you're nowhere near capping your GPU with 3x 980s.

Update: I'm still having framerate throttling and overall poor fps issues. I recently had to roll back my nvidia driver as the latest was causing blue screens (see screenshot of crash report). Since then my nvidia settings went to default and my performance is terrible in places like warspear with 15 toons with cpu, gpu, ram not maxing out, but gpu ram is maxing out. mbox's feedback helped no slot, all cpu. If possible check out all the screenshots below of my settings and let me know what I'm doing wrong. Thank you in advance.

First of all, I don't think any good can come from touching anything in the nVidia Control Panel unless you're attempting to increase image quality. So, set all of that back to default. Beyond that...

• You're using DX11 which is going to eat through your VRAM incredibly fast and I highly doubt you could multibox 15 characters in DX11 on only 4GB of VRAM. So, switch to DX9 and that will solve that.
• New character models eat up extra VRAM, so disable that.
• While your Control Panel indicates you have SLI enabled, the monitoring program shows that you do not since only one GPU has any load on it. This is either a problem with the monitoring program, or... you don't actually have SLI enabled.

In addition to that, you can also drop your resolution since you're trying to play all of them at practically 1920x1080, which is suggested in the Wiki page you linked:

As a last resort, lowering the game resolution may significantly improve framerate as well.

It says "may," I say "will."

First off thank you for the swift reply, I always learn something! I've read through much of the documentation and many of your videos and sometimes I just get stuck.

One setting worth tweaking recommended by EVGA is "power management mode" setting it to maximum makes the video cards work to their highest performance. It helped with spike fps needs as the cards are working at top performance all the time.

I called EVGA and asked them about why no "load" data is showing on the 2 other cards they said do the 3dmark test and if there is an improvement in the score then sli is working and something is wrong with the monitoring program. That said on all monitoring programs this is the case load doesn't show for 2 other cards. I have done tests with sli enabled/disabled and disabled my computer can't handle 15 clients with it enabled it is possible.

I don't quite understand what to tweak so the other wow windows will render at smaller resolution. I thought even though u have small windows in the layout they will still render at 1920x1080. Is this something i tweak in isboxer or in wow client?

You are right about that. I always have that set through nVidia Inspector, and rarely think of it these days.

I called EVGA and asked them about why no "load" data is showing on the 2 other cards they said do the 3dmark test and if there is an improvement in the score then sli is working and something is wrong with the monitoring program.

I have done tests with sli enabled/disabled and disabled my computer can't handle 15 clients with it enabled it is possible.

I don't think the issue warranted a phone call, and I assumed you would just try another monitoring program—Like HWiNFO, MSI Afterburner, or GPU-Z. I find it odd that they're not reporting load on the other GPUs when I've used all three of those programs with my SLI setup and everything reports correctly. It could be something with your driver or GPU. /shrug

However, you didn't mention anything about moving from DX11 to DX9.

I don't quite understand what to tweak so the other wow windows will render at smaller resolution. I thought even though u have small windows in the layout they will still render at 1920x1080. Is this something i tweak in isboxer or in wow client?

Almost all of the time, whatever size Region 1 is set to, will be the size that every region renders at. If you want to lower the resolution of every game client, then drop the size of Region 1 in your Window Layout to something smaller than what you've got. You're currently using a non-standard resolution, so I'd suggest just creating a new layout using the Wizard and setting the Main Window Size to something smaller—like 1600x900—in order to keep the correct aspect ratio.
