VGA Dummy Load

[WhitehawkEQ]

I'm going to be making VGA dummy loads, this is the start of what I have. After I have final design I'll send it off to board shop to be made

Cool!

Here's a vintage thread we had here showing the same process.

Making VGA-Dummy Plugs

Making VGA-Dummy Plugs By Jolly-Swagman When running Multiple GPU's in one System, especially in Vista or Win 7 you need to have extra Monitors hooked up to the GPU's in order to have them GPU- Folding@home Now if you Dont have extra Monitors connected to the GPU's another way is to Fool the...

Is the load for the same purpose as the original thread or more for headless server requirements?

If the former, I’ve never run into that issue, certainly not in current times. Course, I’m not running Win7 anymore I don’t recall it being an issue when I did.

There was an issue like that with some RTX3000 cards while mining BTC. I don't think I have seen it in F@H, but probably the same thing. For example, my RTX3060's performance was ~50% lower when it wasn't connected to any monitor.

Implicitly only useful on VGA-era GPUs. Curious why the need for them.

I vaguely recall they added that limitation to try and hinder mining on consumer GPUs. It was not difficult to work around by using HDMI dummy plugs, but still an added cost/inconvenience to miners.

I had a bunch of HDMI plugs myself because without a monitor connected, if I use VNC to remote to a system it would give a tiny resolution that can't be increased. This seems to be a feature of the driver as I saw this with AMD and Nvidia, but not Intel iGPU of the time. RDP doesn't suffer this, but has other bigger problems. VNC is like being there so everything works like normal. RDP is more like a virtual session and connecting/disconnecting breaks things.

This is partly for the exercise in making PCB circuits and also all the dummy loads I've seen had resistors soldered in a kludge, I'm making it all neat and clean Do I have to do this? no but it's fun And dummy loads are still being made so I thought I'd throw in to

Final design, I have "VGA Dummy Load" on the back.



Connector I'm going to use



To go in this

 

[WhitehawkEQ]

Turns out the connector and size of the PCB would not fit the shell, here is what I have now as well as the shell from last post.

The numbers that are backwards is on the bottom side of the PCB. (note: how can you yell if "8" is backwards? )

 

[WhitehawkEQ]

According to UPS, my boards as shown in last post should be here at 12:00pm today, yeah right when have they been on time

 

[freeagent]

I have 3 still that I got from the forum here, I have them in a box somewhere still, I will try to locate them for donation if needed.

 

[WhitehawkEQ]

Delayed won't be here till tomorrow.

Here's one I bought from one of the Folding Team members, Torin I think:



If you want it, PM with your shipping addy.

Me? I don't need you to send me anything, I got 25 little boards on the way to make 25 dummyloads

I didn't mean to offend you, it wasn't charity, just offering support like I would to any Folding team member.

No offence taken was a bit confused as to why you were offering to send me the one you have when I'm set to make 25

 

[WhitehawkEQ]

They are here.

Yea well that wasn't apparent until after I made the offer.

Daaaawww, HoozAGudCircuitBoard? HOOZAGUDCIRCUITBOARD???

Why'd you go SMT with through hole connector?

Circa ? 2009 ? I think I still have a couple of those.
