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?
-
If you look into the 5570 and 5770 lines, you will find they only provided 4 vRAM chips or 6 vRAM chips, however, RTX5000 requires 8 vRAM chips. That vRAM rows take a large area on the logic board, which would be the main factor the 5680 abandoned the SODIMM memory.
-
Dell is saying RTX 3000Ada with 12GB, that’s typo?

-
Yes, it's thin chassis, since the GPU board is only soldered with 4 vRAM - which means 128 bitwidth -> A1000-A2000.
-
I found they made a link for Precision 5480 but no 5580 nor 5780. Did they cancel the 15 and 17 inch 5000s😭 https://www.delltechnologies.com/asset/en-us/products/workstations/technical-support/precision-5480-spec-sheet.pdf

I am looking for the vBIOS that comes with the Precision 7670/7770 to unlock the performance limit on my Precision 5770, which only has a 70W configuration in its vBIOS. I have only been able to find a vBIOS for the A3000 12G on the ThinkPad P1, but I believe that flashing it to my 5770 board may cause system errors.
-
Dell exchanged my system and ordered a Precision 5770 for me to replace my old 5760. The vBIOS configuration on 5770 is 70Watt, I am looking for the vBIOS on Precision 7670/7770 with A3000 12G to unlock the limits on 5770. I cannot find it anywhere even on techpowerup. Is anyone willing to extract vBIOS?
-
The new XPS 15/17 have 60Watt dGPU(including 4080), that would be a funny story if a 60Watt RTX5000Ada is on Precision 5000series

The poor thermal performance is not only shown on Aaron’s unit. An earlier 7770 unboxing from a Chinese forum, Chiphell.com also reflects poor cooling performance. ~6300 multi-core performance in CPU-z with a i7-12850HX installed and around 5000 GPU score in TIME SPY with A3000 installed. The A3000 installed on Precision5760 can reach around 8500 level. The performance is throttled due to the thermal limit as the GPU hotspot has reached over 80 Celsius degree. The TGP is actively limited to 55 watts simultaneously. I am guessing the new heat sink design does not fit to these high end chips, and the to re-paste the thermal paste won’t really make a huge change. btw, PTM7950sp is a good choice for laptop heat sink. I am hoping Dell can apply vapor chamber heat sink like 5000 series did in the next generation 7000series MWS…
-
These scores are not as high as what HX series should be. I got 13338 multicore score on my precision 5760. There should be a huge improvement on multi-core as intel advertised.

https://www.chiphell.com/thread-2431029-1-1.html, the smaller one comes with the 7770, the larger one comes with previous models
-
Amazing! Congratulation that you have received your new laptop, and thanks for sharing your experience. I am hoping to see more performance analysis from you. From the link you posted, the results are not public due to some reason, can you post some screenshots?

Almost same. Dell China Rep said all 7x70 orders will be pushed to June 14th.

According to the Dell Rep in China, the order can be offically ordered on June 7th and the factory will also accept order on that day. I believe 7x70 will be available in all market on the same day.

Dell China now sells xx70 only

DOO really helps SSD and palm rest cooling, for my 5760, the SSDs (Dual SN850 @PCIe4.0 x4) keep at 25-30 celsius degrees at low workload. I got this image from Also, see this file https://www.delltechnologies.com/asset/en-us/products/workstations/industry-market/precision-thermals-brief-042320.pdf, more desciption relating to DOO system in Precision 5000 series This file is more about Precision 5750, in fact, 5750 5760 5770 share the same cooling system design with minor changes in CPU and GPU layout on the motherboard.
