Dell G7 7790 Owner's Lounge

Starting a thread for G7 7790 owners to discuss and share about their experience with this laptop. Please also state your configuration and share your findings. Thanks

 

I was thinking of grabbing one of these - what are the thermals like vs say a Razer Blade?

 

Thermals are bad with stock paste, acceptable with liquid metal repaste. I have 15" model, the only difference is slightly longer heatpipes. If you are not willing to repaste - consider other laptop models by other brands, like Lenovo Y740.

 

What makes the Lenovo thermals better? How are they in comparison to a RB15? Mines burnt out at 100 degrees solid after a year of use.

 

Lenovo Y740 has larger heatsinks, with more fins and larger air exhausts. Dell G7 and G5 has really small heatsinks and small air exhausts. Lenovo also uses better thermal paste, the paste Dell uses is really poor.

 

Are you saying you think the Lenovo gaming laptops have the best thermals atm? I don't see how a single heat pipe config could be "best" by any means.

 

Number of heat pipes is irrelevant if the heatsinks are too small or have small amount of fins. And yes, if you want best thermals and don't care about display quality or battery capacity - Lenovo Y740 have the best cooling out of similar laptops.

 

Mine just came in the mail, and i'm loving it...anyone got throttlestop numbers? msi afterburner?

I'm very excited to upgrade my memory, and eventually the screen to 4k: i've currently got 32gb hyper-x 2666

So all n all the rig is a g7 7790 17" w/ 9750H CPU/ 2060 GPU, 32gb @ 2666mhz...no overclocking yet.

-yes re-pasted w/ grizzly liquid metal, great cooling as is...and could prob switch out to let's say the new alienware m17 r2 larger fan/ copper pipes, i dunno but would like to see your guys's overclock/undervolt numbers...

I got my laptop for $1300 w/ tax from a amazon 3rd party.

 

I currently play 2019 games w/ w/o RTX at 60/fps @ 1080p on epic /utra...including the recently released Jedi Fallen!

Main is MK11, Tekken7, Jedi fallen, Wolfenstein Young Bloods...

I'm wanting to upgrade my M.2 drive. Anyone have any recommendations on brand/type?

 

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!:
https://www.reddit.com/r/Dell/comments/kpaouc/g7_15_7590_uefi_unlock_undervolting_and_remove/
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.

 

Did you ever have any luck finding out the part number and getting the heatsink applied to the 7590?

 

Not too much forum activity on this machine. Must be a good one.

 

My daughter bought me a 1 TB WD Black SN750 SE NVMe SSD for Christmas. Wasn't able to install it until today. It took maybe an hour of investigating/researching, maybe 20 min of cloning the drive, then another 30-40 min of troubleshooting when Windows' Disk Management wouldn't extend the C: to use the rest of the unallocated drive space (I had to install a 3rd party disk manager tool). Also, when I copied the partitions from the old M.2 to the new M.2, it broke Bitlocker on my data drive, but that was easily fixed by copying the drive's BL key from my Microsoft account and using it to re-establish access to the data drive.

 

Wish I had your capabilities to upgrade the hard drive in my Dell 7790.

 

Edited to delete double post. For some reason this forum now has a timer that clicks away and you have no idea if your post was posted so you just click upload again resulting in double post.

 

I watched quite a few Youtube videos on how to upgrade M.2 drives as well as copying data from the old drive to the new one. And, mistakes were still made, but I've been messing with PCs awhile (and I'm a security engineer by trade).

I think you should be able to do it, as you'll be copying your drive contents to the other drive, so there should be no loss of data. Or, you can reinstall the OS onto the new drive (you can copy from the old M.2 to the new drive later). Either way, you shouldn't lose any data.
