Precision 7530 & Precision 7730 owner's thread

Thanks brother. This slipped from my radar. Will add it in. +rep

This will depend on the notebook manufacturer.

 

Only manufacturers that permit undervolting in the bios will be able to undervolt at all. Which means only gaming/niche laptops are expected to.

 

soooo...
life is quiet and I had time to experiment. I have good news:
- I downgraded BIOS to 1.6 (just because I still had that file on my USB key), I reset BIOS settings -> undervolting worked again
- I upgraded to 1.12 and reset BIOS settings (just in case) -> undervolting still worked
- I upgraded to 1.13 -> undervolting works.

It didn't work when I first downgraded from 1.13 to 1.12, so my guess is that you have to downgrade to a BIOS version old enough in order to be able to re-enable undervolting upon resetting BIOS settings.
Here 1.6 worked for me, but a newer version prior to 1.12 might have worked as well.

 

Nicely done. Maybe I will try to upgrade, then.

 

I had what sounds like a similar noise, it was the M2 heatsinks / covers in the slots where I didn't have a drive installed. I padded out the empty slots with a little foam & is stopped the rattle. It was driving me nuts!

 

Big news.

I have no idea why or how, but G-Sync works with my Quadro RTX 5000 in a Precision 7530. I am running the 451.58 Quadro/NVIDIA Studio ODE drivers, and the notebook is currently in switchable graphics mode with direct GPU output enabled.

The notebook is plugged via DisplayPort into an LG 27GL83A monitor, which doesn't even have a proper G-Sync module—it's only 'G-Sync Compatible', which means it uses VESA adaptive sync instead of NVIDIA's proprietary module.

Spoiler: G-Sync Tests

 

Ok, interesting. Figured it was always a soft-block preventing adaptive sync from working with Quadro cards, there is no technical reason why it should not work.

Trying to tease out the difference. Does the "Set up G-SYNC" option on the left menu appear if you do not have an adaptive-sync display connected?

I am on Precision 7530 / Quadro P1000. (Haven't dropped the RTX 4000 in yet.) I have a FreeSync display connected and that option does not appear. It goes right from "Adjust desktop size and position" to "Set up multiple displays".

Suspecting that this is just a new "feature" on the 450 driver branch. I'm on 443.18.
(Also I have the monitor connected via HDMI, maybe I need to try DisplayPort.)

 

Nope, it goes away when using the internal display. Said option, even on desktop NVIDIA GPUs, would only appear when connected to a display with the appropriate adaptive sync hardware.

Right, perhaps I need to add some more nuance.

When I didn't enable discrete GPU output with switchable graphics, I could not even get an output from the mDP port (monitor sort of detected it, but stayed blank), and could only connect the HDMI cable to the monitor. Oddly, the HDMI output the signal from the dGPU, not the integrated one.

When connected via HDMI and adaptive sync was enabled on my monitor, I could only get a maximum (non-dynamic) refresh rate of 100 Hz.

With it off, I got 144 Hz.

When I enabled the direct dGPU output option in the BIOS and rebooted, the mDP port output to the monitor, too, and the output worked both with HDMI and DisplayPort. I switched to DP only, and unplugged and set aside the HDMI cable. I then checked the NVIDIA display control panel, and was surprised to see the G-Sync option there, and I proceeded to configure it.

I was determined to get DP working rather than HDMI, so I haven't checked that G-Sync works with the latter, yet.

 

OK, also interesting. I have the direct dGPU output option disabled. I normally have the monitor connected via USB-C-to-HDMI adapter so that both the external and internal display are working off of the Intel GPU. (Either the Intel GPU or the HDMI adapter that I am using doesn't like FreeSync, because if I enable it on the monitor side, I just get a blank screen.) I moved it over to the HDMI port on the back of the laptop, which outputs via the dGPU no matter what, for this test. The monitor does work with FreeSync enabled while connected this way, but there was no option to configure it in the NVIDIA control panel.

Didn't realize that the dGPU direct output option would make any difference with the monitor directly connected. That's strange. I'll try to remember to switch the setting next time I reboot and see if that makes FreeSync work. I don't have any cables with mini-DisplayPort on both sides which I would need to connect this monitor via DP.

 

Neither did I, honestly. The two-fold reduction in latency (bypassing Optimus, and with G-Sync) is nice.
