You can do that, but you also need to replace the original camm interposer. The interposer used along with the pure CAMM board is thicker than that used along with the SODIMM daughter board. You may ask the Dell Advisor to order the daughter board and interposer.

A thin spacer is needed when your case is not a performance one. I installed the SODIMM mechanism on a thick spacer in the performance case and everything works. Buying a thin spacer for a performance case is a waste of money.

To note. WWAN cards/slots are B key and NVMe drives are M key. You need an adapter to fit a NVMe drive in the WWAN slot.

 

I'm talking about something else, why use an adapter in WWAN if you can install a 2230 SSD instead of a Wi-Fi module. If DELL allows the installation of a 2242 in WWAN, you could have bought a 2242 SSD and adapter in the store DELL, but the store only had 2230 SSDs and this instead of the AX211. Of course, we understand that to sacrifice the AX211 for an SSD, we need an alternative for wireless internet, and such a sacrifice is acceptable if we have a working WWAN option.

Did you install the 2230 SSD in the WWAN via an adapter? The WWAN is 3042. The 2230 SSD can be installed instead of the Wi-Fi module.

 

 

No i only use 2242 SSD.  SN520 works, but under device manager>USB, a ! USB item will intermittently appear and disappear thru out the session, not affecting actual use. Earlier i thought it is because of other peripherals since i connect to the Dock 90% of the times.

 

I have emptied the WWAN slot for 2 weeks since it is not performing to its max.  SN520 can only run at 260MB/s.  Other SSDs that can run at >1GB/s need to go thru a guaranteed blue screen crash everytime the laptop boots.

I found wwan lid in ebay, but where i can search antennas? any recommendations where i can  found those?

[Mambucho]

Received the order, the cover with antennas came in the factory box, with a double protective film. This cover is for the version with an infrared video camera. If you have a cover with a single video camera, you will need to move the cable and video camera to the new cover

Not for 4K! The 4K version does not support WWAN.

Hello

Have any of you been able to undervolt with bios mods, etc. AC loadline. I am considering upgrading to a 7680 from a 7540.

I get great battery life on the 7540 if I disable turbo boost and let the dGPU go to sleep. 7-12h depending on use. (-110 mv cpu/cache i9)

Hello! 

 

Do you think there is a possibility to put a RTX5090 graphic card in a 7680 Precision?

 

Thanks for your help! 😉

No. No one makes such a card. The one from the Pro Max 16/18 Plus will not fit.

You can look at a Thunderbolt / eGPU solution.

[capitainealbator]

Hello @Aaron44126, thanks very much for your quick answer 🙂

 

I saw the DELL Pro MAX 16 Plus but it only offer RTX PRO 5000 (blackwell) 

Please could you tell me where you saw that the DELL Pro MAX 16 plus supports an RTX5090 graphics card ? ... This would solve my problem 🙂 🙂

 

Many thanks for your time

To get a GeForce card for one of these workstations you must contact a sales rep, it is not available as an option on the web site.

(I am actually not sure if they are offering 5080 or 5090. They will only have one option for GeForce.)

Has anyone seen a difference in performance with the 7680 on a power supply higher than 180W (original for mine)?

The thin version is necessary for a device that does not have a high-performance enclosure. I have a performance case, SODIMM RAM is set to the thickened version and everything is working. I listened to you and bought the slim version and regretted it, I lost the money.

appreciate this information, I believe mine is a non-performance one (without a discrete GPU, only the intel i9-13950HX processor), when I tried to install a SODIMM interposer with the RAMs with the default thick plate that came with the CAMM memory module, the back cover of the laptop would not fit. This explains why, thank you. Will purchase the thin plate. Was also curious how you came about to find out about this information, seems pretty niche 😂

 

On a side note I tried to recently replace 83Wh battery with a 93Wh one, while the 93Wh battery fit into the enclosure the battery connector wire was not long enough for the 93Wh battery, any information regarding the part number for this longer battery connector ? 😄

recently bought the dell 240W charger, yet to see any noticeable difference but in theory it should be able to make use of of the additional power for intensive tasks. Will update after tinkering around abit

Have you heard of anyone using a screen protector on these units? My 7680 has the non-touch screen and it looks like a plastic, anti-reflection surface. It seems that wouldn't be conducive to a good seal for the "gorilla glass" protectors like we use on cellphones. I might be better off with a thin microfiber between the halves when closed since it's screen protection I'm after.  Thanks again to all for the amazing amount of info here!

nah personally unless its a touch screen, I would not opt for a screen protector

@MambuchoI purchased a sodimm interposer with thin plate for 32gb x 2 RAMs, unfortunately only 1st slot works with both RAMs and second slot always results in 4 white + 2 amber lights indicating memory error. what might be the issue ? 😞

I also had this problem at the beginning, when I installed a thin SODIMM plate, there were 4 white flashes and 2 orange flashes, and the power button indicator disappeared. This is not a sign of a device malfunction, so do not worry about the thickness of the plate. Reinstall the CAMM, start the laptop, then turn it off through the "START" menu, and then remove the battery. After installing the SODIMM, make sure that the pressure plate is evenly secured without any distortion, and that each bolt is tightened in turn with a small step. I changed the CAMM to SODIMM several times, and it started. SODIMM initialization takes a few minutes, and if the initialization is successful, the button indicator should not turn off. Be very careful with the contact plate, as the contact may fall out if it is touched with any object.

When installing SODIMM 32×2 (64), the memory will be reduced from 5600MT/s to 5200MT/s, as it should be

@Mambucho Thanks for your reply will try this out and update. May I clarify if you faced the exact same scenario as me ?Because the RAM gets detected with 32gb on first slot just don't know why installing ram on the second slot always results in the 4 white + 2 amber error. Even just installing 1 ram stick on the second results in the same error

@MambuchoNo luck man, I tried what you recommended but the second slot of the interposer just does not work, the first slot that is nearer to the connector always works with both my RAM sticks.

Yes, that's what happened to me, but then it started working. Do you have XMP 3.0 memory? I read about this issue somewhere, but I can't remember where, and it seems that the default profile is set to 4800 MT/s, which causes an error if it's a SODIMM with XMP, but the DP 7680 BIOS doesn't have a profile management mechanism for DDR5 XMP. I managed to get it working after several CAMM-to-DDR exchanges, so you might need to try more times. I installed the SODIMM board with DDR×2, then I left it for 30 minutes, then I exchanged it for CAMM. You need a little patience, but you can run the DDR modules. I managed to do it

@Mambucho ok let me try a few more times, by the way what is your rationale for doing the CAMM-to-DDR exchanges and also when you left it for 30 minutes you mean when the 4 white and 2 amber lights were blinking ?

DDR - CAMM - DDR exchange was an attempt to run it by luck, I didn't want to think that I had lost money. I bought a SODIMM DDR5 -5600 XMP.3.0, and I found "4 white and 2 yellow flashes", I thought that this was the initialization of the memory, and I waited for a long time. Then I realized that this was a problem, and I installed CAMM again, and I did this several times, and miraculously, the power button did not turn off when the laptop was on, and I waited for about 4 minutes for the correct initialization.
