Precision 7560 & 7760 Owners' Thread

It was working correctly before I turned off Hybrid Graphics in the Bios and then turned it back on. It was after it was back on everything was just using the Nvidia Card.

Edit, well there is a Intel Graphics Command Center. I wonder if that could have fixed it too.

 

What I wanted to say is when you turned off "Hybrid graphics", Windows may have changed the preferred GPU to the be performance one (the dGPU, the only one available with "Hybrid graphics" off) and let it that way when you enabled "Hybrid graphics" again.

 

I think in a way that is correct. Once I disabled the Hybrid Graphics, Windows defaulted to the NVidia and only way to get it back was the uninstall of Nvidia. Just a guess.

I found where it says the intel driver must be installed first. It is on the Dell Nvidia driver downlaod.

I'll note that if you do some sort of mixed mode (internal display on Intel GPU, external display attached to NVIDIA GPU) then you'll often see apps "stuck" on the NVIDIA GPU after you disconnect the external display. You can restart them to get them to use the Intel GPU, but sometimes it's system apps like the lock screen which aren't easy to restart. You can avoid this sort of thing by turning the discrete mode output setting off and attaching your external displays via USB-C. (Everything will be running off of the Intel GPU, just like on the internal display.)

I'd agree with you regarding reinstalling drivers when switching hybrid graphics on or off. If you decide to switch hybrid graphics off again later you should not only do a full reinstall of the NVIDIA drivers, but uninstall the Intel GPU drivers (maybe using DDU).

 

Comments after removing the bottom panel.
It's a bit different than I expected, being used to the Precision 7530 again. The entire "side" of the chassis comes off, not just the bottom. Not bad, though, I just "pried" starting with the smart card slot and pretty soon the whole thing just popped off. No broken tabs or anything as far as I can tell. Still a little bit trickier than removing the 7530 bottom panel.

The PCIe4 SSD slot has a weird plastic enclosure that detaches separately. Maybe this has something to do with making the drive easy to remove through the bottom SSD door (which I do not have). I found installing another drive in that slot to be a little bit tricky. It did not show up in the BIOS the first time I tried and I had to go and re-seat it, so I did not have it aligned quite properly or something on the first attempt.

Right now I have the system with 2× 512GB SSDs (one of them came with the system, one is from my Precision 7530) and also a new 4TB "Sabrent Rocket Q4", which is a PCIe4 drive. Working through data shuffling right now. I think that I should be able to finish it up tonight and use this as a production workstation for work tomorrow. I'm just using the Windows install from my Precision 7530 (and Precision 7510 before that) so after installing some drivers I should be good to go pretty quickly.

 

Which Slot did you install the 4TB?

 

I haven't noticed popping sounds yet

 

It’s PCIe4 so in the PCIe4 slot. (It’s not the boot drive and that seems fine.)

 

Count yourself lucky I guess. It’s simple to reproduce for me. This was with the stock Windows image to boot, not my old crufty one that I am moving over.

 

Would the SATA work of you have the RAID on in the bios? This is what it says. Just a thought when I saw SATA. If so, maybe RAID On is better on the newer machines?
