However, my subjective opinion is that it appears skinnier and less wide due to the combination of the new hinge design and the curve of the back panel. 1 Link to comment Share on other sites More sharing options...

Expand Like @Light said, the new ones are a little bit less wide than prior generations (7740 and older), but not by a whole lot. It holds a standard 17.3" 16:9 panel; the bezel on the left and right side is pretty narrow but unlike the modern XPS 17, there is still a think bezel on the top with the camera and a very thick bezel on the bottom with the "Dell" logo. I just recommend that you pay attention to the chassis options that you want (SSD door or no? fingerprint reader or no?). Unlike 7670 where some options are forced on you, 7770 seems to allow just about any combination that you'd want, other than WWAN+4K not being an option. My experience ordering through a sales rep (both personal and work purchases) is that they don't tend to pay close attention to this point so you'll want to check the quote and make sure that its exactly what you asked for. 1 Apple MacBook Pro 16-inch, 2023 (personal) • Dell Precision 7560 (work) • Full specs in spoiler block below Info posts (Windows) — Turbo boost toggle • The problem with Windows 11 • About Windows 10/11 LTSC Reveal hidden contents Apple MacBook Pro 16-inch, 2023 (personal) M2 Max 4 efficiency cores 8 performance cores 38-core Apple GPU 96GB LPDDR5-6400 8TB SSD macOS 15 "Sequoia" 16.2" 3456×2234 120 Hz mini-LED ProMotion display Wi-Fi 6E + Bluetooth 5.3 99.6Wh battery 1080p webcam Fingerprint reader Also — iPhone 12 Pro 512GB, Apple Watch Series 8 Dell Precision 7560 (work) Intel Xeon W-11955M ("Tiger Lake") 8×2.6 GHz base, 5.0 GHz turbo, hyperthreading ("Willow Cove") 64GB DDR4-3200 ECC NVIDIA RTX A2000 4GB Storage: 512GB system drive (Micron 2300) 4TB additional storage (Sabrent Rocket Q4) Windows 10 Enterprise LTSC 2021 15.6" 3940×2160 IPS display Intel Wi-Fi AX210 (Wi-Fi 6E + Bluetooth 5.3) 95Wh battery 720p IR webcam Fingerprint reader Previous Dell Precision 7770, 7530, 7510, M4800, M6700 Dell Latitude E6520 Dell Inspiron 1720, 5150 Dell Latitude CPi Link to comment Share on other sites More sharing options...

Dublove Posted November 2, 2022 Share Posted November 2, 2022 Hello all. Wondering if anyone else is having strange problems with a brand new 7670? Here is what is going on with mine. Dell support case opened, but they are not grasping what I am saying! 1: Humming / Fuzzing type noise through laptop speakers. (all the time, even when external audio is active using Ultrasharp U3421WE monitor audio). Humming / Fuzzing type noise from under keyboard. (Coil whine?) Occurs when mouse is moved, when graphical elements of Windows UI appear on screen such as opening a window. & when graphics load is high such as 3d application use. 2: Laptop in sleep mode for less than 1 hour. Humming/purring noise coming from laptop speakers. Spacebar pressed to wake laptop up. Fans came on at mid rpm for around 2 minutes, laptop did not wake up. After around 2 minutes laptop reboots by itself and goes into Windows blue recovery mode. Startup repair selected, laptop reboots and stalls at Dell bios full screen logo. Laptop powered off (power button 10 sec). Powered back on, left at Dell logo for around 10 minutes, at which point Windows loads. No events in Windows Event viewer regarding this - it has a time gap in the logs when this occurred., 3: Laptop display screen. (4k Old) Screen randomly changes to intense brightness/contrast/over-saturation. Has occurred multiple times, and keeps happening. Sometimes on initial power-up, sometimes during using the laptop, could be 10 minutes, could be a few hours. Restarting laptop, the screen returns to normal. (this is the only thing that makes it return to normal). The overbrightness is more than can set by manually adjusting the display brightness. Ambient light sensor seems to be adjusting display when there is no change in ambient light. Disabling auto brightness in display settings has no effect. 4: UFEI Bios. Update from Command Update application. Firmware update displays successful installation progress on bios. However subsequent Command update shows not installed. On third Command Update attempt the Bios update is installed, but took 15 minutes waiting at the Dell bios logo before booting into Windows. Also have some strangeness when changing the optimised/quiet setting. It takes 30 minutes or so to boot back up past the bios each time this is changed!!! This really suggests to me something is fundamentally not right... UEFI hardware diagnostic reports no issues or errors. Windows 11 Pro is up to date. Dell Command Update all is up to date (drives / bios). Would welcome anyones advice! Link to comment Share on other sites More sharing options...

Expand call Dell's customer support and ask for replacement unit, plain and simple, don't try to explain why just say this unit is not working for me its overheating, i want a replacement or to return the unit, they are aware of heating issues with the 7670 and wont argue trying to save the sale by sending a new replacement asap. (i just returned two 7670 for overheating, both original order and a replacement unit went back, just put it to performance mode in bios and you will have native solid 80-90c at idle reason 😉 ) the impossible is not impossible, its just haven't been done yet.

I don't use sleep, but this is probably "Modern standby" (which no one seems to like) at work. Unfortunately, there's no way to go back to S3 sleep in this system (AFAIK). Use hibernate instead? 3. This is normal stuff from the Intel GPU. A few settings to disable. First go to Settings, System and turn off "Change brightness automatically..." at the top. Next, go to the Intel Graphics Command Center, System, Power, and turn off adaptive brightness and anything that says "power saving". 4. Don't go to BIOS to change the optimized/quiet setting. Use the Dell Power Manager app. You can change it on the fly while the system is running. (I don't know about Dell Command Update offering the same update over and over again. I've heard other users complain about that before. I don't use it, I just grab updates individually by hand from the support site. I have RSS feeds set up to be alerted when new ones drop.) Finally.... 1. I will echo @MyPC8MyBrain here, these noises seem like a hardware issue. Contact Dell support and they will either start swapping parts out or just replace the whole thing. I can say that this is not happening with my 7770 (and I am pretty sensitive to high-frequency noise). 1 Apple MacBook Pro 16-inch, 2023 (personal) • Dell Precision 7560 (work) • Full specs in spoiler block below Info posts (Windows) — Turbo boost toggle • The problem with Windows 11 • About Windows 10/11 LTSC Reveal hidden contents Apple MacBook Pro 16-inch, 2023 (personal) M2 Max 4 efficiency cores 8 performance cores 38-core Apple GPU 96GB LPDDR5-6400 8TB SSD macOS 15 "Sequoia" 16.2" 3456×2234 120 Hz mini-LED ProMotion display Wi-Fi 6E + Bluetooth 5.3 99.6Wh battery 1080p webcam Fingerprint reader Also — iPhone 12 Pro 512GB, Apple Watch Series 8 Dell Precision 7560 (work) Intel Xeon W-11955M ("Tiger Lake") 8×2.6 GHz base, 5.0 GHz turbo, hyperthreading ("Willow Cove") 64GB DDR4-3200 ECC NVIDIA RTX A2000 4GB Storage: 512GB system drive (Micron 2300) 4TB additional storage (Sabrent Rocket Q4) Windows 10 Enterprise LTSC 2021 15.6" 3940×2160 IPS display Intel Wi-Fi AX210 (Wi-Fi 6E + Bluetooth 5.3) 95Wh battery 720p IR webcam Fingerprint reader Previous Dell Precision 7770, 7530, 7510, M4800, M6700 Dell Latitude E6520 Dell Inspiron 1720, 5150 Dell Latitude CPi Link to comment Share on other sites More sharing options...

ATAN Posted November 2, 2022 Share Posted November 2, 2022 Anyone with a precise measuring tool who can avoid using hillbilly western measurement standards and has a little bit of time to measure the mounting dimensions for the CPU I would appreciate it. I'll do it myself soon if I have to, I just don't have functional calipers rn. As crazy difficult and tool-wise expensive as it would be, mounting a small vapor chamber in place of the copper cold plate might give a little bit more thermal headroom. Maybe not as well as the nuc series but competitive, seeing how it uses only a small vapor chamber and small but dense fin stack. I also am looking into thermoelectric coolers for docked usage, doubt they will fit thought. Not that it's very user friendly, and honestly it's easier just to expand my custom loop and/or pull a De8aurer type move and try making a custom loop/waterblock for 2-5 7770s in cold cash, clearly I'm not that insane. Just doing the modding research before its time to commit to it or send it back, which is soon(tm). On the same note I'm looking at the Alienware/Lenovo all amd laptops, taking the performance bullet, not that I don't get the same/worse all (8p) core perf on my 7770 on anything besides single core benchmarks and games. (77w pl1 still but 3* cooler with the Honeywell 7950) vs amd apus. I just want it cooler so I'm not doing a Mobo/cooler swap in 3 years because it sat at 90-97*c most of its working life. Also it seems like it's cooler can't really sustain a few hours of heavy work at above the 70-75w range, not that I do that often. Really makes me wonder why they don't even have a single vapor chamber config for this machine, but I digress. On a brighter note, zen 4 mobile looks promising from a perf/watt perspective. If I don't keep this or get the m17 then I'll just wait again for the 3rd time 😂 maybe a winmax 3 that could offer slightly better performance on all aspects along with a SSD door on the rear. Also hp support said, in reference to the zbook fury 16 g9, I had to get the a3000 config for a vapor chamber, an $1200 a3000 that I might have to disable just to use my egpu, not the half price pro 6600m that would just work. So that's out the race, don't want a $4000 machine in which I only needed half of it. Really makes the Lenovo and Alienware 6900hx/6850xt configs look nice dispite massive storage nerfs. I've been brought down to my bare minimum requirements of 2 gen 4 m.2 slots without a SSD door(Dremel go burr), 5700g level performance, and egpu compatibility w/o funky Optimus business with my 6900xt. I'll miss the nice looking 7770 tho, only a little though. Man if they still made thin itx boards, along with the new HDPlex GaN PSUs I'll be using in my updated egpu build, I could probably make a slightly thicker but way better laptop for my needs.. If only I had a 3d metal printer. Link to comment Share on other sites More sharing options...

It would likely not increase overall thermal capacity much if anything reducing it, the thing it would help is short term boosting performance for non constant workloads, ie Geekbench lol. On the opposite end, adding raw mass (copper or alluminum) can provide short term gains as the issue was never it's ability to cool itself/soak heat but rather it's limited thermal capacity overall. To which adding small heatsinks wherever I can fit them has netted small gains but unless I was to be adding actual weight it would not be useful outside of soaking 90w for slightly longer and letting the vrm breath a bit. Not even mentioning the fact that it takes a lot of skill not to damage the VC or heatpipes themselves On another comparitive note, the 7770 egpu should still technically be faster than the average laptop for gaming as they tend to give the power budget to the GPU. So to each his own. Edit: not to mention how vapor chambers that would fit within the mounting size would have rather low thermal capacity. I'm just shooting the shits and trying to take a duece on dell as I just want 10-20 more watts sustained capacity. Link to comment Share on other sites More sharing options...
MyPC8MyBrain Posted November 2, 2022 Share Posted November 2, 2022 @ATAN did you try LM TIM? that with bit of undervolt should do the trick (provided your silicon agrees with your undervolt), i was able to eliminate throttling on the 7670, for that i had to undervolt cpu core -165Mv and cpu p cache -150.4, at that point (actually bit before at around -120mv on p core) thermal throttling was eliminated, i could see turbo spikes up to 147w and settles around 77w after boost, 1 the impossible is not impossible, its just haven't been done yet.

Not even mentioning the fact that it takes a lot of skill not to damage the VC or heatpipes themselves On another comparitive note, the 7770 egpu should still technically be faster than the average laptop for gaming as they tend to give the power budget to the GPU. So to each his own. Expand Should be easier to get the stock heatsink for systems with a GPU? https://www.ebay.com/itm/295059238559 1 Link to comment Share on other sites More sharing options...

Expand 7670 heatsink: 7770: I would not say that this looks like that much of an improvement. But if it has to be a Dell then it is most probably the best you can do. 1 Link to comment Share on other sites More sharing options...

Expand for @ATAN case i love that idea (very smart!) much better than tailoring a vapor chamber solution from scratch, this can potentially smooth some spikes not having a GPU below, more copper will do the trick and that should fit right in like a glove, @1610ftw there is another heatsink design for the 7770 with more fins and a plate over the dGpu area on the top and a bigger bottom plate, with a much beefier heat pipe instead of the thinner one, if you scroll back to @Aaron44126 early images you will see it there, On 7/30/2022 at 1:55 AM, Aaron44126 said: Expand 1 the impossible is not impossible, its just haven't been done yet.

1610ftw Posted November 2, 2022 Share Posted November 2, 2022 Thanks, just found it as a spare, too: https://www.ebay.com/itm/225171289649?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=vEvDB76LRTS&sssrc=2047675&ssuid=qo2ADUZqR_-&widget_ver=artemis&media=COPY That should hopefully result in substantial improvement for @ATAN 2 Link to comment Share on other sites More sharing options...
FlashWolf Posted November 3, 2022 Share Posted November 3, 2022 Good Day my fellow Dell precision 7*70 mates, First i want to thank you all for your efforts, you really help us alot with your research about this laptop generation. So, my Dell precision 7670 has the same problems as yours, thermal throttling and about 15,5k points in cinebench r23. i already did the loadline and resizeable bar fix in efi and added arctis mx4 thermal paste. the temps are horrendous also after that modifications^^ the temps are maxing out at 107° in idle 😅 now i try to undervolt the cpu but somehow if i unlock the voltage for the cpu p cache and add for example -2 mv it instantly keeps crashing. somehow it looks like my cpu does not like undervolting of the cpu p cache at all? whereas the cpu core allows me an undervolt of -160mv and e cache about -30mv. is this a problem related to my windows or do i have a bad sample of cpu? here are my specs: i9 12950HX RTX A2000 8GB 64GB CAMM 16" 500nits Display 2TB Samsung Pro 980 thanks in advance, 1 Link to comment Share on other sites More sharing options...
MyPC8MyBrain Posted November 3, 2022 Share Posted November 3, 2022 @FlashWolf i cant post screenshots for you i returned my 7670 unit few days ago, going off memory so follow these steps to the T, start by deleting your ThrottleStop.ini than open TS, in TS Main window 1. in Settings section, Uncheck SpeedStep 2. in Settings section, Check "SpeedShift - EPP" 3. in Settings section, Change "SpeedShift - EPP" value from 128 to 34 (you can edit exiting value) 4. Click "Save" (bottom left window corner) click TPL tab 1. in Power Limit section, Uncheck "Disable Controls" 2. in Power Limit section, Uncheck "Clamp" from Long Power PL1 3. in Power Limit section, Change value for "Long Power PL1" from 85 to 77 4. in Turbo Power Limit section, Check "Lock" checkbox 5. in Miscellaneous section, Check "Speed Shift" 5. in Miscellaneous section, Change "Speed Shift" Max value to 68 6. Click Apply than OK on the bottom right of TPL window Click FIVR tab 1. in Save Voltage Section, Select "OK - Save voltage settings after ThrottleStop exits" 2. in "All Core" Section, click on 47 setting all cores in "Turbo Groups" to 4.7Ghz 3. in "FIVR Control" Section, select "CPU Core", than check in "CPU Core" Section below "Unlock Adjustable Voltage" and drag "IccMax" slider to max 255.55 5. in "FIVR Control" Section, select "CPU P Cache", than check in "CPU Core" Section below "Unlock Adjustable Voltage" 6. Click Apply than OK on the bottom right of FIVR window exit TS at this point and open again, you are now ready to begin undervolting, start with undervolting your CPU Core first, Click FIVR tab in "FIVR Control" Section, select "CPU Core", in "CPU Core" Section below use "Offset Voltage" slider in increment of -5mv at a time from 0, apply and run a mixed cpu gpu benchmark like 3DMARK (CB23 not sufficient!) if bench completed with no issues increment another -5mV and so on, when you reached your cpu max undervolt limit back off +5mV, once CPU Core been udervolted, you can move on to undervolting CPU P Cache using the same process, you do not need to undervolt anything else beside these two variables, on my CPU i was able to achieve -165mV on CPU Core and -150.4mV on CPU P Cache, do not try to jump to these values each CPU bin is individual! in bios you want to set ultimate performance power plan and turn Hybrid Display off, few pages back i posted step by step guide how to repaste properly, with 107c idle it sounds like you need to do a repaste before you should begin undervolting, Good Luck 1 1 the impossible is not impossible, its just haven't been done yet.
