Dell G7 7790 Owner's Lounge

G7- 17 7790 here. RTX2060 I7-9750H
No issues. Runs cool. Not a gamer. Lots of open programs, (Excel, Work, Access, etc.) Always plugged into main power. Video editing using Vegas works fine. No issues with any MS updates yet. Dell also seems to be updating something ever so often and requires reboot but no issues with that either. Doing Zoom conferences also with this machine. Not a machine you would want to lug around but excellent for home office use.

 

I'm awaiting my G7 17. I'm interested in the possibility of installing a 144 HZ LCD at some point. Does the 60 HZ model use a 30 pin cable and if so does that mean you can't change over to the 40 pin replacement screens I'm seeing being sold as replacements?

 

As I have said here many times before, people need to stop fixating on if a temp goes up a deg or blah blah and just use their machines. Yes, the Lenovo has "better cooling". that means it is 2 deg cooler than the dell. It's not magically going to have liquid cooling desktop numbers.

 

Hello, I need a part number:
The dell G7 7790 comes with a PCH heatsink, it is black and runs between the RAM slots.
The dell G7 7590 does not have this heatsink but has the mounts for it, it seems dell is aware there was a PCH overheating issue and included this in the 7790 to prevent it.

The Dell 7590 has the exact same motherboard as the 7790, it simply has more or less the same heatsink with longer pipes on one side, and metal spacer brackets to make extra room between the motherboard and IO board, so this part is compatible.

I cannot order one without the serial number.
This could help dell G5 and G7 owners alike who do not possess the 7790
In exchange, I bring you this guide which will 100% work for the 7790, you may have different values, so take apart the bios for IFR values to verify, but otherwise you can enable undervolting on the newest bios!:

if you repaste and undervolt the cpu like this guide suggests, you can reduce temps substantially and hold 3.9ghz boost on an i9 9880h, probably higher on the 6 core i7 models.
GPU should only run about 70c.
With the physical mods in comments the fans make a lower pitch whoosh instead of an annoying high pitched whirr.

 

Thanks for that info. I have the G7 7790 17 inch with i7-9750H, 6 cores. So far it has not heated up doing basic video editing.

 

Can you take the back off and take off the black heatsink between the ram slots that covers the pch? I really need a part number, the 7590 does not have this and the PCH gets fairly hot, I want my laptop to not die early.

 

Sorry, I just don't have the time right now to take the back off. Maybe someone else that has this model will reply to your request.

 

one or two of the barely active people who haven't posted in over a month here? lol.
