Precision 7530 & Precision 7730 owner's thread

Hi there.What is the reason behind the aluminum foil around the graphic card?.



Is it possible to upgrade the 7730 without it?
Thanks.

 

EM shielding, and improving heat dissipation. Its not absolutely necessary, but Dell has put it there for a reason. If your card comes without it, then don't try to jerry-rig a new one, and just use the card as-is.

 

Thanks for your quick answer.
Do you know if it has an independent part number?.Or the shielding usually comes as a whole ?

Also,besides Dell.....where can I find a reliable source for the parts needed to upgrade the 7730?.The reason I am asking this is that Dell is out of stock for the flat head screws.And I am trying to upgrade an intel gpu only 7730 unit.

Thanks in adavance for your help.

 

Just to confirm what is probably already known to be true, poor battery life definitely appears to be down to the dGPU not powering down completely. I've done a few tests with switchable graphics on and dGPU not engaged (confirmed via Nvidia GPU Activity monitor / nvidia-smi.exe) and with switchable graphics off (only using dGPU) and projected idle battery life difference was a miniscule 15 minutes between the two. This makes running on dGPU only a little bit more appealing as it yields better CPU scores in benchmarks, though interestingly 3d mark GPU scores are a few 100 points lower when switchable graphics are disabled.
Wondering whether the same issue exists on the new 7540?

New BIOS just arrived. Version is 1.12.1.

Below are the changes. Looks like there's quite a number of fixes:

 

Yes, with 1.12.1 my <Fn>+up/down keys are working again, to control display brightness.
No issues so far.

 

I've upgraded and now brightness is not honored by the panel. :-(

Anyone knows how to report a bug? Or do I just go to support (I've downgraded and can control brightness again)?

 

You have to go to support. Make sure that you are using the Dell-provided graphics drivers because that is the first thing they will want, they won't support a problem if it works with their drivers and is only an issue with the upstream ones. Give them clear reproduction steps and your system configuration (including whether you have graphics switching turned on or off). Hopefully you get someone whose first inclination is not "let's just start replacing parts" and it will go to the engineering team to attempt to reproduce the problem. If they are able to reproduce it then it should get fixed... after a few/several months.

 

...or I'll just wait for the next revision and hope for the best...

 

Just received and installed a 144Hz panel (NV156FHM-N4B) to replace the crappy 45% gamut one. Predictably colours, contrast and general smoothness of everything are far better then before. Install was really simple and probably one of the quickest swaps I've done thanks to a rubbery bezel cover that popped off really nicely. Negatives are a definite low frequency PWM presence that occurs at any brightness bellow 100%, also colours have a bit of a red shift to them (will try to get it calibrated), which i dont mind as much as colours having a blue shift.
This seems to be the only 30 pin 144Hz panel that is available currently, so will be definitely keeping it.
