Precision 7530 & Precision 7730 owner's thread

My system has a ATI Radeon Pro WX 4150. I'm guessing anything related to nVidia doesn't apply?

I've always had to wiggle the cable to get things working again, but that's not working this time.

Monitor 1 (7730): 2048 x 1152
Monitor 2 (LG 43"): 3780 x 2160 via DP
Monitor 3 (Dell U3014): Can't check now, via mDP.

I've been using this setup for about a year now with the occasional dock related quirks. This is the first time that no matter what I do, I can't get monitor 3 to work.

Device Manager shows the monitors detected and active, both graphics cards detected and active, and no exclamations or alerts.

I'm stumped and annoyed at this.

 

You're right, Optimus is not applicable with an AMD graphics card, but there should be a similar option in the BIOS for switchable graphics. I think the AMD equivalent is called Power-Express. Is it possible that one of the external displays has a refresh rate set above 60 Hz? There are some resolution & refresh rate limitations to the TB18DC (see "Setting up an External Monitor" section here). Looks like the U3014 is 2560x1600 so you shouldn't be running up against these limits as long as you're not connecting one of these via HDMI or VGA. As a test you could set the refresh rate on the working display to 30 Hz.

One thing Dell suggested when troubleshooting the dock was to unplug the dock from the laptop. Then unplug the dock from it's power supply. Next hold the power button on the dock for 10 seconds. Reconnect power to the dock, then connect the dock to the laptop.

 

What's interesting is that this morning the third monitor is working again. I don't know why or how. I took the 7730 home to use last night. This morning when I plugged everything in that third monitor is functional. It's possible that some combination of the holy-#@%&-frustrated cable wiggling yesterday + plugging the dock back in today did it. <shrug>

Yep. Every time I've run into issues I've done that. And until now that process got things running again.

Thanks for your help. I'm back in business until the next time this combination flakes out again.

 

Has anyone ran into choppy performance with video playback when using the Intel graphics? I've found a temporary solution that involves doing a clean install of the HD graphics drivers but after a reboot, problem comes back. Disabling the iGPU solves this, but obviously with a dip in battery life and extra heat output.

I've got the 7730, i7-8850H, and the P3200.

 

Hi guys, I have a 7530, i7 8850H, P3200 that I'm interested in upgrading the ram and maybe the ssd. Right now I have the stock 16GB 2666 CL19 memory and I use it for CAD work and editing large .pdf sets ~500MB. My head is spinning with all the posts I've read about whether or not the 7530 will run faster memory. Would 128MB (4x32) of hyperX 3200MHz, 20-22-22, 1.2V; 2933MHz, 17-19-19, 1.2V, and a Sumsung 970 pro make remarkable improvements to how fast big .pdf sets are rendered and CAD models handled? Hoping for PnP stable options.

 

Improving the memory speed (slightly) is unlikely to make any meaningful improvement. Improving memory capacity might. Look at the Task Manager performance tab and the "Memory" graph — if you are approaching 16 GB used then it is probably paging stuff out to disk and you should get some more RAM.

Improving the SSD speed might if the bottleneck is the disk. You can check this just by again having Task Manager open while doing your work and looking at the graphs on the performance tab. If the SSD is maxing out during your load then you are likely to see performance improvements by making it faster; if it is not, then you are bottlenecked on something else (CPU probably) and it won't make much difference.

I had a lot of issues with my TB18DC docking stations. One of them then completely died and was replaced by Dell last week. Interestingly, since they replaced that one dock, I have had significantly less issues with both of them.

The cable remains finicky. But after I got a pair of USB-C right-angle adapters, the connection is much more rigid. I think the tolerances on the usb-c thunderbolt connectors or both the 7730 and the TB18 are way too loose, and using a cheap adapter actually compensates for that on both ends.

 

What does that look like?
