Which brand are u using? SK or Crucial? in Dell specsheet sodimm 64gb is 5200Mhz, so 96Gb still can get 5200 is considered good not dropped to 4800. Only up to 32GB will run at 5600Mhz. This is set by Dell bios i think.

With ssd on WWAN slot, it will guarantee a crash during every laptop startup after shutdown, with windows BSOD error code of "Internal_power_error". The laptop will restart and the next reboot will load the Windows normally, and the wwan ssd works like normal. It is unknown of how to tweak the bios or windows setting to avoid the first crash. Not many people is using this slot for ssd. Once I removed the wwan ssd the crash is gone.

Cleaning the fan still requires dismantling the entire heat sink. I miss the legendary 6700&6800 so much. The fins are plenty with small gap, normal cotton bud won't work anymore, need something flat. Brushing won't work that good at my place, the dirt is simply just too much. Imagine this machine is just 2 months old. the fan is spinning hard so i decided to clean it.

Sorry what i meant was i did not go to look at gpu utilization whether it is high or low, i just run the ai denoising only.

@Kaj E 7780 13950hx RTX5000 is 16sec. I did not observe the gpu utilization anyway.

What do you mean no IPS? it is always available. Talk to the sales perosn if you can't get what you see on website, Dell is hiding some options from website customization list.

Just upgraded the old WD19TB Dock with WD22TB4 upgrade kit. Now there are 2 TB ports on dock which i need them all. I have 1 generic USB hub connected to USB3 port from the Dock. keyboard mouse soundcard etc are connected to this generic hub. Multi monitors setup without laptop screen, so the dock & laptop is far away & need usb hub for peripherals. Now i received the "too many USB hubs" warning message from windows. Some items under USB Controller have "!" marks. Searching on the web I found someone having the same issue with 19>22TB4 upgraded dock. https://www.dell.com/community/XPS/XPS-9710-WD22TB4-quot-Too-many-USB-hubs-quot/m-p/8403898 I believe this is Dock issue & not laptop problem. Dock Firmware is latest. USB spec is up to 7 tiers, I don't understand how it is calculated in this situation.

Kingston has 5600Mhz ECC sodimm, I wonder if that will work with 7780?

For this full metal case laptop, it is difficult to hold with 1 hand while putting in or taking out the laptop from the bag. Earlier much heavier and bigger 7720 can be easily handled with 1 hand but not with this metal case. It is just too slippery. Anyway full metal case does look & feel premium. 7780 heat can penetrate through keyboard area and felt hot. No need to run benchmark, just enter bios for some times and the heat can be felt. 330W brick is good, but current heat dissipation design cannot handle it.

I use another ssd i created 2 weeks ago with Win10. From there i can update the bios without problem. I do not know why i cannot do that in Win11 21H2. After updated bios, i switch back to the ssd with Win11 21h2. When i click the 1.22 bios file, i can now see the content (earlier it was empty), and bottom button is now "Update" and not "Accept".

I am not sure if this is because of me overwritting the earlier W11 22h2 partition with 21h2, the dell bios recovery is broken and i did not install dell bloatwares back. I only have command update. I still have the old 22h2 image together with boot partition. I will restore it and try if bios update will be back to normal.

Hmm, I have problem updating bios either by running the exe file; or using Command Update; or running F12 when start up. Command Update will return update failed message. Running exe file just stop at page below:- Press F12 during startup and select update bios by choosing exe file, nothing happened after that. Current bios version is 1.1.0 Does that mean my bios is corrupted? I still can enter bios to do any setting. I downloaded .rcv file too but not sure how to use it, it is for bios recovery. I tried download older bios 1.1.0 to install and yet the same thing happened, so the 1.2.2 exe file is not corrupted.

This is to confirm that the WWAN slot can support up to Gen3 x2 b+m key 2242 NVMe SSD (x3 and above will not fit). The best possible ssd could be WD SN520 but max capacity only 512GB. I bought a never seen brand "Kingspec" 1TB SSD with advertised speed lower than SN520 but i need the capacity. Upon installed, the sequential write performance of this SSD is very disappointing. Copy 250GB image file, average speed is only 250 MB/s (Switching between 100MB/s and 680MB/s every few seconds depends on cache) vs advertised speed of 1000 MB/s. I am not absolutely sure if this is because of the limitation of the WWAN slot. The price is cheap anyway. The SSD at WWAN slot cannot be detected in the bios, so it is not bootable. Another important thing is that the SSD must be formatted before installing into the WWAN slot. A brand new SSD will not be detected in the windows.

Used Rufus to create bootable Win11 21H2 and install. The result indeed is closer to Win10 Memory Integrity ON https://www.3dmark.com/spy/38310340 Result = 16229. GPU 16227, CPU 16532. Memory Integrity OFF https://www.3dmark.com/spy/38316514 Result = 16360. GPU 16249, CPU 17026. Memory integrity has slight impact on CPU. Compared to Win10, both GPU and CPU are lower but the difference is not much. So it is confirmed that Win11 22H2 is causing big CPU performance impact. Better to stay with 21H2.

I searched around the web and found a number of people point out Win11 22H2 is the culprit. Older Win11 21H2 has similar performance as Win10. Hmm where to find 21h2 bootable usb...

Just got an unused 2230 ssd to install win11 from zero. All other ssd removed. After driver & windows update 1st program installed is 3dmark. Not touching graphic and power profile settings. With memory integrity ON, Result = 15814. GPU 16146, CPU 14165 https://www.3dmark.com/3dm/93836345 Disable memory integrity and restart PC, Result = 16236. GPU 16627, CPU 14332 https://www.3dmark.com/3dm/93836926 So disabling memory integrity in this case improved GPU score slightly and for CPU basically no difference. I would say in this fresh Win11 the GPU score is 5% better than earlier Win11 (not far from Win10), but CPU score remains the same, far from Win10 CPU 17318 Out of interest i change from RST to AHCI and run the test. There is no impact to the result. Result = 16184. GPU 16527, CPU 14482

If it is about memory integrity, it has been turned off because my old Logitech G19s keyboard driver won't load otherwise. Both OS are using Dell nvidia driver. I noticed if nvidia website driver is used, under nvidia control panel the "display mode" tab (when using laptop alone) will not be there. It is where user can select either automatic/optimus/nvidia only. Whatever chosen will not affect 3dmark score anyway it is more for battery saving.

I just installed Win10 Pro on an unused ssd and run the test. Bios setting unchanged. The result difference is huge. Win11 15573 - GPU 15912, CPU 13899 https://www.3dmark.com/spy/38208390 Win10 16873 - GPU 16797, CPU 17318 https://www.3dmark.com/3dm/93785961 For Win10, GPU is 8.3% faster and CPU is 24.6% faster (this is too far off!) I haven't tried VBS/HVCI and Turbo Boost 3.0 thing, but i don't think that is the issue. default setting without changing anything in Nvidia control panel and power profile, the difference is just too difficult to accept. Not sure what is wrong.

I have enabled Ultra Performance profile and run the benchmark but the result has no difference. Tried Nvidia GPU only mode still the same. Could it be Win10 Pro is actually better for 3dmark GPU & CPU test? 😐

GPU temperature not more than 74C, CPU no more than 78C. During CPU test alone is 100C. Both my GPU and CPU scores are lower than yours, especially CPU. laptop alone means without dock. Power profile is default balanced. https://www.3dmark.com/spy/38208390

I am using WD19TB3 240W. For laptop alone, i tried Timespy custom 1080p the GPU score is 23516. Timespy default (1440p) is 15600~15900. I am not sure if @win32asmguy is running 3dmark at default setting or custom 1080p. The benchmark default setting is 1440p regardless of max lcd resolution. 3dmark can run 4k test on 720p monitor.

Yes i have the 145W power too. Just done benchmark on laptop alone, Timespy (custome 4k) GPU score is only 8617. Timespy Extreme GPU score is even lower at 8200.

I ran Timespy and graphic score is 15,800. That is with default driver and external monitor of only 1440p. Not yet try to run on laptop alone. CPU temp at 100C during cpu test. GPU temp max 73C

Shouldn't be a problem with 8TB. My old 7720 is using 4TB without single issue. I use AHCI anyway i always hate intel RST and i do not configure ssd into raid. If you are buying SSD from Dell, even though it is a Samsung, u can't use AHCI and install Samsung NVMe driver on it. Dell purposely did so. There are things that cannot be done easily under RST i.e. using bootable usb to do something unless the driver is injected in the usb.

7780 only has single LED, no more individual hdd and power LED. There is no way to know if the machine is still running or properly connected to power with lid closed. The LED just lit up for a few seconds after powering up, then it turns off and i never see it lit again until shutdown. Not sure what is the purpose of that LED. Really poor design.
