Of course, just enable the overclocking option using grub.

Let's see

I have done the repaste, but sadly, nothing improved. When I opened up the heatsink, the paste is not spread evenly, and the upper part is core 1,3,5,7, which can explain the problem I am facing now. Should I ask Dell support to send me a heatsink replacement?

High temp P-core: 1 3 5 7 High temp E-core: 12 13 14 15 | 20 21 22 23 4 E-cores for 1 cluster Looks like one side of Die is not fully contacted with the heatsink. So, maybe the pressure of heatsink is not balanced?

Short term workload: Long term workload: (reaching 77W:)

1. Yes, indeed, it's with PTM 7950. 2. directly on the table with 2 bottle caps in between. 3. Room temperature is ~22 celsius degree 4. CPU workload is very low before I started the benchmark. I will check the core temperature later, and update it here. Even without too much change in cooling design compared with Precision 7670, the thermal performance is much worse than 7670. Precision 7670 can have the peak watt at ~157W and keep for a few secs.

Good news here: 48GB*2 5600MHz SODIMM works pretty well on 7680 (running @5200Mhz bcz dual channel)

I have fresh installed Windows 10 LTSC on it. Peak CPU power is still not what I expected, but benchmark somehow increases: CPU-Z single core score is pretty high, is it normal? (The CPU voltage is set correctly by DELL?) CB R23: CPU-Z: With CPU voltage offset(-0.125v): 3D Mark TimeSpy:

Yea, that's also what I am concern about, when it's 77W, it stabilized at ~90 degrees

I just received my Precision 7680, it shows an extremely poor performance with thermal throttling. Configuration: - i9-13950HX - RTX 3500Ada I don't know if it's in a similar case as what we saw on Precision 7x70 before. I do replace the thermal paste with Honeywell 7950 thermal pad for both CPU and GPU die. - CPU throttled at ~110W (100 Celsius degree) - CPU idle temp at 70 Celsius degree. Anyone is facing a similar issue? CPU-Z looks like: Temp and package watt looks like when running CB R23 benchmark: CB R23 score:

Yes, the ram will operate at 4800MT/s

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.

Has anyone tried the new RAM spec (48GB * 2) on their 7770/7670? I thought it needs some special support in BIOS, so not sure if ours support that.

Comparing my Precision 7670 (Perf. chassis) and XPS15 Comparing my XPS15, MBP16, and 5770

It surprised me that the Precision 5680 is designed to have a removable GPU daughter board. Dell released a video 2 weeks ago:

Can confirm Precision 7670 can be charged with USB-C power adapter in system, and works fine.

Having a quick chat with Dell sell advisor, they can order GPU board of 7x70 directly. btw, I am in Canada. Let me ask about 7x80 spare part. Update: Dell Canada can order the GPU card up to RTX 5000 Ada Gen for 7x80, and the bad news is 4090 laptop GPU is not seperately sold. I guess Dell Canada share the same store info with US. ** "this model" refers to Precision7x80, not finally confirmed by Dell that 7x70 can support Ada Generation card

Is it possible to order a GPU daughter board of 7x80 from Dell? Does anyone have some experience in ordering parts from Dell directly?

Yea, that's also changed on 7680. They finally made it.

Hope Dell can provide a model like a combination of WD22TB4 and WD19DC, so that users can still have ability to connect 2 thunderbolt devices when the WD19DC dock connected😃

Does it mean the system can accept power up to 210w with the WD19DC plugged in? My 5760/5770 meet battery drainage when the system has a high workload, good to know Dell tried to improve the power option for the 5000 series.

I would say there are no stability or warranty issues. The chip is exactly the same between different models if the A3000 is installed. The only issue you will encounter is that only 3 of the 4 Thunderbolt 4 ports will work for video output in the Windows system (Linux works perfectly). The 5770/5760 models have a vapor chamber installed, which has a high heat capacity to handle the graphics card working at 115 watts. Similar to the operations that have been done in the 7770 owners' thread (modifying voltage shift for BIOS settings), the vBIOS upgrade will not cause you to encounter warranty issues. At least for me, my 5760 was exchanged by the Dell support team for a 5770 with no argument regarding the vBIOS change.

Having a quick search on other forum, Someone is able to convert DGFF to M.2 connector, it looks like the right DGFF is for PCIE x8 only, that is matched what I thought. On 7550, it has 3 DGFF connectors for x16 PCIe lanes, and on 7760, it has 2 DGFF connectors for x8 lanes, can confirm 1 DGFF is responsible for x8 data transfer, and 1 DGFF is responsible for other signals handling. They must customize some pinout that it can pass through the fan PWM signal.

On the old 5770, the 65W limits can be unlocked by flashing 7770's 130W vBIOS, that what I did on 5760. However, I still haven't found shared vBIOS from 7770/7670

I just have a quick look into the Framework 16, I found they are using a DGFF connector?
