Precision 7530 & Precision 7730 owner's thread

Of course it is. But it happens. The memory calcs are done using a completely different pipeline, though, so no, it's not computed by the same hardware at all.

 

XTU is known to be notably less flexible than ThrottleStop; there are also reports of it interfering with fan curves, which require full Windows reinstalls to get rid of.

 

I don't think this is a Dell 7530/7730 specific phenomena. My HP ZBook 15 G4, with a UHD Dreamcolor display (with panel also made by Sharp) and a matte finish/coating, just like the Dell, has the same screen door effect. I initially didn't expect this at all given that it's an IPS display.

I believe it might have to do with either the matte finish/coating on the display or some property of certain Sharp laptop panels.

 

Thanks for taking that picture @Aaron44126 , it looks like you have a more even backlight.

Idle temps seems to be around 38-41 °C (23 °C room temp) measured by Realtemp GT (Load jumping around 3 % as noted by Realtemp, "nothing" is running). At the same time my Asus have 33-36 24°C (load 0,5%)

Is it an IGZO panel? Maybe it have something to do with that?

 

Optimization on my 7730:
(1) Changed Memory to 3000 MHz Cl 16
(2) Changed SSD to 2TB Samsung 960 Pro

On high load there are many CPU-slowdowns (thermal throtteling) with up to 99 degrees Celcius and big temperatur jumps between low- and high-load.

 

To me 38-41 deg C (with 23 room temp) are completely normal and actually good idle temps if your setup is with discrete graphics in the BIOS and not switchable/hybrid graphics, plugged in, and no undervolt. My HP ZBook G4 it idles around 41-43 deg C in discrete graphics only mode with this setup. The dGPU makes a difference to all thermals. Only with the dGPU off have I ever been able to get 33 deg C idle.

The Sharp display on the HP ZBook G4 is an IPS panel

 

The UHD panels in the 7530 and 7730 are also IPS (in-plane switching).

IGZO (Indium-Gallium-Zink-Oxyde) is the type of transistor used to make the panel. IGZO allows for higher resolutions than the traditional aSi (amorphous silicon) used in FHD panels.

Like @kittenlips said, those are normal idle temperatures.

The ~100°C temperature under load are high, but there's not a lot you can do about that, except undervolting with the risk of an unstable system. As other people have stated in this thread, the cooling system used by Dell (but also HP and Lenovo) is inadequate for the TDP (thermal design power) of high-end 8th Gen Core CPUs combined with Quadro (and possibly Radeon Pro) GPUs.

Personally, I think the screen door effect is caused by the anti-glare coating. AFAIK, there's no glossy UHD panel option in the 7530/7730 to compare.

Exactly, any laptop that uses the same (or similar) panel will have the same screen door effect. AFAIK, only Sharp uses IGZO panels, so there's no way to compare with other manufacturers to say for sure what's the cause of the screen door effect. My money is on the anti-glare coating, though.

 

So (sadly) I've read through every post of the thread to catch myself up.
I just ordered a 7730 with the following (main) specs:
i9-HK / 8GB RAM (will add my own) / 256GB NVMe (again, add my own) / 6-cell battery / backlit keyboard / next fingerprint reader

and a Quadro P5200......

So it seems this thing is a Max-Q variant that isn't "full" power. I have an Asus Zephyrus 1080-MaxQ laptop myself. I'm looking to consolidate machines while I'm on the road and not carry the thin Asus around. Is there a decent enough performance gap for (some) gaming between the P4200 and P5200? Or should I call and cancel my order and grab the P4200?

Seems like a decent system from what most everyone says. I currently have a fully loaded Dell XPS13 that will be my backup system to this one when I'm on the road.

Thanks!

 

Fellows! I decided to take off the bezel and loosen the screen while the machine was running. And, voila! No bleeding and an more or less even display (dark spot is gone). I have now found out that the dark spot (and bleeding) is cause by the attachment of the bezel and maybe the display itself. This may not be a surprise to you... I would claim that all bleeding-issues people complain about on laptops, is due to inappropriate attachment of the screen and/or bezel. My dark spot seem to appear when i attach the last part of the bezel lower right. So right now, the bezel is on, but i didn't push in the last attaching points in lower right. It is still possible to close the screen. Maybe i keep it like this...time will show. :O)

 

The p5200 is MaxQ and the p4200 is not MaxQ? I'm having trouble finding the post with benchmarks or with hwi and gpuz screenshots showing this. I seem to remember the 7530 had a MaxQ but I thought the 7730 was not maxq. Maybe I interpreted it wrong and now I can't seem to find the posts that mentioned it. If you see the post can you link to it again? -thanks!
