what is the TGP reported in the Nvidia control panel of the RTX 3500 Ada on the Precision 7680 originally?

Hmmm, I’ll have to see if the 330w charger changes power limit. But the 3500 on the 7780 is listed the same as my 5000 as 115w, which is the default for the optimized power profile. The max TDP allowed is 145w on mine, so not sure how he got 160w on a lower card. It’s a moot point really because stock this thing can’t take 145w for more than 3min before it hits the 87c limit and starts to throttle, mine originally settled at 125w. New pads, PTM and blocked off the internal fan exhaust and I can just barely maintain 145w, and that’s on a cooler pad. Without pad it would throttle down again since right now it sits at 86.7deg.

These systems come with two different lids (display enclosures) depending on whether or not you have WWAN antennas.  The non-WWAN version has an all-aluminum lid.  The metal would not be helpful for connectivity if you try to put antennas in there.  The WWAN version has a separate (visible) plastic strip at the top where the antennas go.

 

The WWAN version looks like this, note the separate piece with a line across the back/top of the display enclosure.  That part is plastic, and the rest is aluminum.

 

If you have the non-WWAN version then I am not sure where you will put the antennas, but if you can find a spot (either in the display enclosure or in the lower chassis) that allows for connectivity then you should be able to just drop in a WWAN card and SIM card and be good to go.

 

You could replace the display enclosure with the WWAN version (Precision 7670 version would probably fit as well), but the display panel is held in by adhesive, not screws.  So, getting the display panel aligned in your new display enclosure would require careful measurements and steady hands, or be an exercise in tedium.  😕

 

If you have the OLED panel, they might not offer that with a WWAN version...?

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

Just bought an intel BE200 card thinking to replace the AX211.  However it doesn't work after installing.  Not detected as all, nothing shown as if non-exist for wifi and bt.  Has anyone tested with BE200 working with current version precision?

Yeah .... AX211 is actually not a PCIe card, it is CNVi, and it relies on support from the PCH to work.  I am not at all surprised if you can no longer use a generic mPCIe card in that slot.  (AX210 is the generic mPCIe, version but that is not what Dell is using.)

 

Intel should release a BE201 card as a replacement at some point, but it will probably not work in older systems, as it would also expect you to have a compatible PCH.

Just a PSA. Got a second 7780 with RTX 5000 Ada for my co-worker, his came with the 4K 120hz Oled. The GPU power limit is locked by the EC to 130w vs mine 145w on the 1080p 60hz screen. Maybe upgrading his to a 330w adapter might raise it to 145w but not sure if it’s worth the extra 250$

 Wow thanks for the information, never know about this design & standard that adds on confusion to consumers.

When using an air-pressured cooling pad like the IETS-GT500/600/626, would there be a benefit in removing this black tape from the base?

The system wants to bring in cool air from the bottom and push hot air out the back.  The "rubber foot" running the entire length of the system at the back creates a barrier that makes it hard for the hot air going out to be immediately re-absorbed by the cooling system drawing air in from the bottom.  If you remove that tape, you might create a situation where hot air is going out the bottom of the system on the right side (as pictured) and then being sucked in by the fans on the left side again.

 

Maybe with a cooling pad there would be so much air moving around that it wouldn't matter much...  I don't see much benefit though, blowing air across the heat fins is the main thing that gets heat out of the system and those are only on the side with the fans.

Just got one 7670 unit as follows:

i9 12950HX, RTX A5500, 64GB RAM, 2TB.

Thing is, everytime I power it on it takes about 6 seconds to give image...never happened to me on a previous notebook, is that behaviour normal?
For the rest is quite allright as far as I know, still that thing buggers me

For me is about 4 seconds, but yes, is normal for workstations in general to boot (and shut off) a little slower than general consumer laptops

About the same for my Precision 7560.  I haven't measured it, but it definitely takes several seconds between pressing the power button and anything showing on the display.

I bought this kit and works at 5200mhz instead of 5600mhz, any ideas?

original rams were 5600mhz and no problem

Dual rank memory (32GB and 48GB DDR5 modules) only supports 5200MT/s by spec from Intel, so you would need a kit with an XMP 5600MT/s profile. Such sticks were offered in the AW m18 R1 but I am unsure how to purchase them separately. I know that the Kingston Fury 64GB kit does not have an XMP profile despite being capable of running at those speeds but other brands might.

could someone kindly look at some of the 5g/wwan antennas of the number 7680 from of the screen top cover and bottom of performance chassis. 

 

I'm planning to update a thin chassis to performance chassis upgrade.  also wwan antennas should be obtained.  does anyone have any knowledge to advise me.

 

Does anyone know where to find a modified bios that would remove the overclocking block??

Can’t help you with the wwan but I can tell you that it’s probably not worth the effort trying to find a modified bios to unlock overclocking. Firstly the only thing that is locked is UV protection, you can OC using an usb tool that unlocks the intel advanced menu. I have mentioned in a previous post along with some tweaks. Overclocking is moot on this system because the heatsink is already undersized for the wattage this cpu needs to run at stock clocks. You will NEVER hit 4.4ghz all core turbo for more than 0.05 seconds. 4.1 for about 10sec and then it starts to down clock mine gets to 3.7 by the end of a cinebench run. Even the GPU at 145watt, with new pads and PTM7950 can barely sustain, 19deg c ambient room temp and hitting 86c, throttling starts to happen at 87c, so unless you can put the internals into an Alienware M18 R2 chassis forget it, probably better off buying that and flashing the GPU to the quadro equivalent if you need those features, if not just leave it alone.

Well finally sprung and got a 7780 through the used Dell outlet. Couldn't see buying a new one with cooling issues. It has the i9, a5000, 64 gig ram and a 4 tb ssd.  My last one was a M6600 lol. After adjusting the fans I got the cooling into a some what acceptable reading. So far pleased with it.

[rintalahri]

I ordered an rtx3500 graphics card and heatsink, and now I need to know what the performance chassis part number is, i.e. the base number. I have thin chassis now.
Could someone please look it up on their own computer, what number is performance chassis, because I can't seem to find the right number in internet.

[rintalahri]

what is the difference between a performance case and a thin case, can I put the rtx3500 in the ada thin case?

So.... Did anyone ever figure out a way to undervolt?

 

another question, did anyone switch from a workstation to a gaming laptop? how do they compare for a work environment? I mean over 8 hours of medium load, are those build to last in those scenarios?

As far as I know the AC load line is the only way to achieve any form of undervolting.

 

I would think an ASUS SCAR would be quite reliable. Also, they are half the price when similarly specced. I mean they might even last longer because you can actually UV, the cooling is 2x as good, I went with the precision for the quadro card, if you don’t need those features then I don’t see why you would get a precision, the scar is 30% faster and has proper cooling out of the box.

Well, things happened...

 

I originally bought a discounted x15 r2 for around 2k usd(12900h, 3070 ti), the thing needed to be repaired so much that when I asked dell for a replacement they eventually agreed to it, I got a maxed out 7780 (13950hx, 4090, 4k 120hz) out of it, and don't get me wrong, the thing is a great upgrade and feels much better quality, but since it has a smaller wattage than gaming laptops and doesn't allow undervolt, now im just wondering if I should sell it and get a gaming laptop, I have the same reasons you mentioned even, better cooling, more wattage, undervolt and cheaper.

 

That's why I wanted to know if there is a more hidden aspect in which a workstation is superior to a gaming laptop, since they are work oriented I suspected they were build to last more, but I'm not sure if that's the case.

The work laptops are more geared towards enterprises. Easier servicing and more locked down so users can’t play with settings and break things to keep IT costs down. If you use your laptop for work, in 3-4 years regardless of which option you go with you will probably be considering an upgrade. I think the hardware itself in both options will outlast their usefulness. I think a gaming laptop may also keep its value better. Depreciation on these pro laptops is brutal. Which is great if you want to buy on the grey market with no manufacturers warranty. If you already got one of these maxed out, I would maybe just keep it until it has run its course and then for the next one look at a premium gaming laptop. That’s what I’m going to do. The SCAR X3D looked damn good. I just really want there to be an AMD powered laptop with a proper Quadro card.

Hey can any of you guys with the 7780 and the 4090 post your VBIOS?

[YukiFuyuEAS]

Hi guys, I know my laptop is a Dell Precision 7740 but this post helped me understand the issues that are somewhat shared issue with Dell Laptops. (I got a refurbished unit)

My Dell Precision 7740 Specs:
i7-9750H
RTX 4000 Quadro

I had it repasted with PTM 7950 and I still get the result of 100c peak temps even with numerous heat cycles for the PTM 7950 however I was able to reduce it down to 92c peak by using a guide from "askthemanager" website by editing the power plan's cpu performance limits. His guide states that it worked for his Inspiron by setting the limit to 85%, for my 7740, I set it to 95%.

The 92c doesn't stay long since once the 7740's fans kicked in, it drops to below 70c. I noticed that after repasting with PTM 7950 and performing heat cycles, there's noticeable decrease in heat, noise and fan usage.
