but you can choose not to install geforce experience with normal nvidia drivers

GFE works with quadro btw, no different to geforce

 

It does, but the fact that even with the GFE option ticked, it does not install for Quadro, is a nice thing.

 

it doesn't?

so you have to download gfe manually if you want it?

 

If your CPU is performing calculation errors (regularly), it will cause a crash. It would be oddly specific if it was only causing computation errors that caused incorrect data output from some sort of compute job. The CPU is doing a lot more than just crunching numbers for your job. It is doing all sorts of things to determine the flow of the computation. Once it makes a mistake that causes it to decode an instruction incorrectly, jump to the wrong address for execution, read or write something critical with a bad memory address, or cause a problem in the kernel or with a driver, or something along those lines, you'll be noticing. Considering how fast the CPU crunches through instructions, if give it a busy job to do, a small number of mistakes (in terms of percentage of instructions)... it might not crash on the first mistake, but the number of mistakes will add up to a big number very quickly and you'll be noticing when one of them crashes the job or the system. For many of the things I mentioned, just one random single-bit error will be enough to cause a crash.

Still as others have mentioned, once you have determined a voltage that is stable under load, you should also check in multiple situations (under a more idle load, on battery) and it is best to use a stress test tool that double-checks its work.

 

Does anybody here have a 4K IGZO screen with more or less even backlight? Would be nice to see... I just got replaced my LCD on the 10 day old 7530. Same issue with very uneven backlight as earlier, maybe a little better. The bleeding is much better. I also got changed the heatsink, but no improvments regarding temperatures at load (actually it seems to be worse).

Here are som images of my Eizo screen in the back, the Dell 7530 left and my old Asus on the right. All displaying the same images in photoshop. All calibrated with hardware calibrator. https://www.naturgalleriet.no/Imagebank-1/Dell-with-replaced-screen/n-DxtWSQ/

The replaced screen was the same as the "old" one: http://www.panelook.com/LQ156D1JW02_SHARP_15.6_LCM_overview_24748.html ... Produced in 2015?

Am i expectiong to much?

 

Did you see the Dell tech apply new thermal paste?

If he applied too much or too little thermal paste, you will notice higher temperatures. Too much thermal paste actually acts as an insulator, reducing the heat transfer from the CPU/GPU to the heat pipe. For optimal heat transfer the paste needs to be applied as thin and evenly as possible. Too little paste will result in a reduced contact surface between the CPU/GPU and the heat pipe, also reducing the heat transfer.

Considering what these workstations cost, I think you can expect a good quality display without backlight bleeding. So, no, you're not expecting too much.

 

Anyone have the 4k on the 7730? If so how is it with regards to backlight bleeding and gamut?

 

regarding dell techs replacing heatsinks and their thermal paste, etc... The thermal paste is pre applied, so if tech replaced heatsink he used the pre-applied paste that is on the heatsink. ALthough I had a tech replace my heatsink once in my 7710 and he installed wrong heatsink. I have Nvidia gpu but he installed amd heatsink. They look identical and same screw hole locations. The paste didn't even fully contact the processors. The temps soared to 90c and kept climbing immediately after bootup. He denied it, even when he saw the temps. He said it was normal. I had to beg him to remove the new heatsink and reinstall the old one. Thats when we both noticed the thermal paste wasn't even disturbed, meaning the heatsink wasn't contacting the processor. Then he accepted that the heatsink was wrong one. Not all techs are bad like that guy was, most have been great with me.
But if that's what Espen is experiencing (wrong heatsink) then the temps on laptop wouldn't just be a little high, they'd be crazy high. I agree, is good advice to double check the thermal contacts/paste with the heatsink and processors, pads, etc and swap to a good aftermarket paste.

 

If the pre-applied thermal paste gets scratched or dented while installing the heatsink, it can create a small air pocket that prevents heat transfer in that spot. The air pocket heats up rapidly and expands, pushing the thermal paste around it outward.

@Espen Bergersen how much higher temperatures do you get?

 

The heatsink came with preapplied thermal paste...if it is good/bad or too much i don't know. See pictures in link below.

Regarding the screen, the bleeding is better, but there is still a large darker patch on the right side. Look at the pictures https://www.naturgalleriet.no/Imagebank-1/Dell-with-replaced-screen/n-DxtWSQ/ I will also add some pictures of the 7530 internals.
