Having DC isnt a deal breaker, just something that doesnt limit the GPU options, LVDS "standard" is 980M max, GuitarG and the DC setup he had was RTX level options, so even if a 4K screen & associated cables unlocks that (or a IPS equivalent for 1080) would work. Yep saw the manafactured date so assume its a new "clone" So i would assume a DC screen to have the interposer board attached to the back of it as the primary cable '401 seems to be quite long to route through the hinge assembly to arrive at back of screen. so i would assume the "secondary" cable off the interposer to be a short one similar to your 30-40 flat one shown up above? if we can get each cable Primary & secondary pinout known / mapped then its really only the interposer board which poses the blocker for upgrades. To add to the options, could the Dell equivalent cable and assembly work if yours uses Dells DC version? Just a thought.

It's interesting, don't you think, that the affair with the alleged Chinese spy was known for quite some time (about a year I think), but Jensen was ousted only this week. Possible explanations (theories): - Trump, a public ally of Jensen's, was weakened by the midterms and this provided an opportunity to circles in the intelligence apparatus/judiciary to act. Probably he (Jensen) was given the choice to step down to avoid criminal prosecution for bypassing the export sanctions to China. This is a guess. - The same circles waited for NVIDIA to acquire the largest git repo of LLMs in the world (i.e. HuggingFace) this September for an astronomical price that made no financial sense - probably someone of these guys convinced Jensen to do that. Then, when the deal was done, they ousted Jensen, setting things in motion to replace them with a guy that will be more friendly to the big AI companies. If we read Anthropic's prospectus for IPO, we will find a statement that open weight constitute a financial risk. Investors in these companies - including the U.S. government itself - could feel safer with tighter open weights regulation. The business model of cloud companies works only if access to AI is regulated. This can be easily codified in law in the name of public safety. Plus, the potential control of the largest hardware manufacturers will restrict the capability of using generative AI without the government taking notice. Thus, the following months will be very important for the future of AI. Is it going to be a public utility enhancing research and development worldwide or a control mechanism for mass surveillance, access to employment, intelligence, etc?

I see 2 solutions: Custom interposer board + LCD cable Using the stock DC cable, one must design a simple interposer board that has an eDP female port connected to the OEM DC cable + retraces the signals to a 40 (or 30) pin standard eDP female connector + use an off the shelf 40 (or 30) pin eDP cable to connect to the LCD (many can be found on Aliexpress) CONS : sourcing a 40 pin female eDP connector (connecting to OEM DC cable) of the interposer board + sourcing a OEM DC cable PROS : much simpler to get a custom PCB made than a custom LCD cable Custom direct LCD cable Create a custom 50 pin to 40 (or 30) pin eDP cable as discussed before CONS : sourcing a 50 pin female LCD port connector used on the 8770w motherboard + getting a company in china to build such a cable PROS : only sourcing one old stock part, the connector

Hello, yes that 8570w cable is different to the 8770w cable, the pinout in your message is correct. You know that eDP cables are coaxial ? They have an inner core wire + insulation + outer ground wire + insulation, all in one cable. They are EXTREMELY hard to work with if you solder by hand, possible but very very hard, very fine soldering + microscope + tweezers are needed. In the factory they are soldered by laser machines, ordering a custom cable is also manufactured this way. Ali cable isn't the end solution, the best solution in my eyes is to ordering a custom cable, or finding the 50 pin male connector + 40 or 30 pin male eDP connector and making the cable by hand (you can by a spool of micro coaxial cable for cheap) The cable is probably a clone since manufacture date of 2019 is 8 years after the laptop release. It probably works fine. Yes if you want a dreamcolor display to work you need an interposer board, but be careful : signals coming from the motherboard to interposer are eDP signals leaving the interposer and going to the display are LVDS The Dream Color display is a very rare IPS display using high bandwidth LVDS signals, that is why they needed eDP (high bandwidth), converted it to high bandwidth LVDS and then send it to the screen. The confusion comes from the fact that the laptop sees this display as "eDP" since it has to send eDP signals to drive the display, the reality is that it sends eDP -> gets converted to LDS -> LVDS display. The cable doesn't "convert" or "talk", that is done thanks to the chip on the interposer board. A full DreamColor display assembly has : Motherboard to interposer "eDP" cable Interposer board converting eDP -> LVDS Interposer board to LCD "LVDS" cable DreamColor IPS display that uses LVDS signals. Hope this clears things up for the Dream Color technology ! this is the same for dell precision also using the DC screen.

so without chasing the new 4K capability, would that be beneficial to the ageing 8570W, (dont get me wrong its a nice tech to have). Would the simpler 30 pin and IPS capability be suitable? Have ordered one of the '401 cables Vladka shared the link to so looking good. I had seen those converters online but they didnt look "intelligent" hence me thinking we were missing the interposer? Thats actually a good logic of having a 50pin to 40pin option and then if 30 pin screen is your thing then just run it that way. Obviously this is all theory and assumes either the 4K screen or the normal 1080 Dreamcolor IPS/eDP screen would function. if we can indeed make the 50MoBo to 40 (or30) pin jump by coupling connectors (with a few rejumpering wires changed) then that makes it way easier than scouring the internet for remaining OEM DC cables.

Hello, Good job, yes this pinout matching is correct. However I would actually wire this to a 40 pin eDP connection with 4 lanes of eDP because that way you can wire the screen up to nicer 1440p and 4k displays with high refresh rate, if you so chose to. If you want a 30 pin screen you can pick up a very cheap 40 pin to 30 pin eDP converter flex cable such as this one, that way you can make these 40 pin cables in bulk and end users can decide to get one with 30 pin converter or not depending on if they want to use a 30 pin or 40 pin display. If you want to make a custom 30 pin eDP cable then the 2 unused lanes should not be connected to anything, just let them terminate on the 50 pin LCD port on the motherboard -> cut the extra unused cables directly on the port.

Did you check on eBay cicichen

It is that for sure. Greed and self-aggrandizing business ventures are agnostic to anything else with no regard to who it affects. The agenda needed for furtherance of the corporate enrichment strategy is the only thing that matters. Anything else is an inconvenient annoyance and distraction. It doesn't matter where their money comes from or how it is acquired as long as it comes. He is really skilled at peddling garbage, that is for sure. And, he is worshipped by his garbage lovers.

Hmmm. Nvidia could start competing with their own partners and offer their own homebreved "RTX Spark" laptop and desktops. I’m sure Cook could contribute something with that... He has the needed experience. And Nvidia already do it with their graphics cards. Why not go into Jokebook business once the AI bubble pops? https://packaged-media.redd.it/gl18keksb81i1/pb/m2-res_480p.mp4?m=DASHPlaylist.mpd&c=wh_ben_en&var=sgpssan&v=1&e=1794549600&s=b364c0dda444b14c99bc08dca240849990c596c8

It's a lack of empathy and a long term perspective, just chasing the next quarter IMO. I'm just waiting to hear how my community is also responsible for this from some people. I'm sure we already have some people transvestigating the Chinese spy.

Exactly. And a clown like Cook would be the kind of moron to take that position.

Jensen came up from the GPU market, so I think he might have had at least some desire to have the fastest GPU and maintain a reputation. We could end up with someone who looks at the numbers and goes "who needs geforce?" and just kills the consumer side.

For business-facing markets it is not too far fetched, but hiring that clown for anything that relates to gaming and PC performance enthusiast interests it would be an idiotic decision. Someone like that nutjob would just perpetuate the likelihood of PC gaming and enthusiast interests continuing to be marginalized and no longer a relevant business pursuit. One need look no further than the crApple product stack and the $hitshow that their garbage represents.

Would you prefer that Cook take over and run Nvidia? I am at a loss for words. President Trump says Apple’s Tim Cook is the only man to replace Jensen Huang as Nvidia CEO

Speaking of "dark times" it appears Micro$lop services are down. Everything Micro$lop is down at work. Outlook, SharePoint, OneDrive, Office suite, etc. and I just checked on my personal computer and outlook.com is inaccessible.

I purchased this panasonic toughbook fz-55 mark 2 on ebay. I have been a long time dell roughbook user (3 generations, still have 7414), and all those machines had the GPS built in and worked flawlessly. Am a USCG merchant marine and do lots of boat work, and deliveries. It has this double round connector on the back that I am pretty sure connects to the dock, and allows one to have an external antenna in the vehicle. Blue and red wires connect to it. The toughbook has the Sierra Wireless EM7511 Qualcom Snapdragon X16 LTE-A in it shown in the attached picture, and device manager shows a NMEA port 19 on the Sierra unit. Putty sees that port and GPS data is being read, although its mostly empty due to no GPS antenna. I have an external GPS bluetooth unit, with a usb cable and it works fine. I have searched on the web for information on this unite. Sounds like a need to buy and internal antenna setup, connect into those two spots on that daughterboard. Then route wire and antenna likely up into the display. Looking for where to get the antenna assembly, and maybe instructions on how to install it.

We are living in dark times worldwide and things stand to get much worse in the near future. Wickedness is a way of life now. Setting aside all of the extremely undesirable political troubles and inevitable fallout looming on the horizon and focusing on the technology space, a huge part of it is a concerted effort to monetize everything and convert personal computing into a subscription model in every way possible. The big players don't want PC enthusiasts or general computer users to own long-lasting, powerful and capable hardware or locally installed software that allows a buy-once/use forever scenario to occur. We can say we "don't blame them from a business perspective" but the intent is self-serving and nefarious at its root, designed to extract every ounce of revenue possible and make being dependent versus self-sufficient the end goal. I do blame them. It's the wrong path for everyone. This touches all aspects of life in the world we live in. Essentially the same business model as big pharma. Nobody wants cures or permanent solutions. They want lifelong prescriptions that feed the pig for the same reasons that big tech wants lifelong subscriptions. The end user is no longer a valued customer, we are a source of revenue that needs to be captured in perpetuity. No thanks. Hard pass. I do blame them and that business model. It's messed up and unacceptable.

Not so sure this will help gamers/consumers. Jensen made graphics cards for games and gamers, what will the new leaders do? They can probably nothing about Geforce and gaming. They will probably put all the eggs into AI and severs. Jensen Huang leaves Nvidia with immediate effect The founder is leaving after 33 years as CEO. The CFO is taking over and the product plan will be finalized. There is a lot more into this. All the smuggling of chips and helping build up China's AI capacity (in the grey market) is probably the main reason. And China... They does what they always do. First fill up (stock up) with chips and vram, then make it work the way they want it.... Modded Nvidia RTX 5090 with 96 GB VRAM and custom BIOS surfaces in China

and... he's out! -> NVIDIA Announces CEO Transition NVIDIA (NASDAQ: NVDA) Board of Directors announced today that Jensen Huang has resigned as President, Chief Executive Officer, and a member of the Board, effective immediately. Colette Kress, current Executive Vice President and Chief Financial Officer of NVIDIA, has agreed to serve as Interim Chief Executive Officer. Kress will continue to serve as Executive Vice President and Chief Financial Officer while serving as Interim Chief Executive Officer until a permanent successor has been named. The Board is initiating a search for a permanent Chief Executive Officer and will consider internal and external candidates.

IIRC, the 8570W cable is different to the 8770W from discussion with GuitarG, I recall the pinout he added to the thread, That said, moving a few cables is preferable to moving all of them...... Best have my steady hands and good eyes that day 🙂 Do we assume that Ali cable is a end to end solution? (could be an equipment pull or an actual manufactured clone) I ask as the "official" has the interposer board which i couldnt see in the Ali advert. Ive also seen the 8770W cables on ebay but again all seem to be missing the board in the middle (assumption is the cable is doing all the pinout changes to make LVDS Mobo and edp/IPS screen "talk" and work. (added in GuitarG's version of the above for 8570W comparison) Just trying to get all the bits to the puzzle...... So 301 is the Normal, 401 is the "dreamcolor". added to the basket 🙂 amongst other ALi items for the machine 😄

news version update by codex https://www.dropbox.com/scl/fi/9ppo0v43dbudvcsptxk6a/DellFanManagement-Rebuilt.zip?rlkey=ptw1dg3nwbkno2l8ezhoppucl&st=8j9pagy8&dl=0

I discovered something else that improves CPU performance. There is an option found on the CPU Power Management Control page that needs to be disabled for maximum CPU performance on Windoze and especially so for Linux. On older BIOS (like I use) it is named "Resource Priority Feature" (sounds like something good, but the "priority" is wrong) and on newer BIOS it will be listed as "HWP Autonomous EPP Grouping" (or something similar to that). It is in the same screen where you disable C-states, SpeedShit and Intel Dynamic Platform Framework crap. This setting allows Windoze to control CPU behavior to conserve energy at the expense of maximizing overclocked performance. Linux is even more aggressive at doing that and the power management crap requires more effort to manipulate in Linux. (Maybe because European countries are more Nazi-like in their quest to reduce power consumption and Linux is far more common in Europe than the US. Just a guess on my part.) Anyhoo... disabling this setting increases my Cinebench scores by about 600 points and also see higher CPU-Z single and mult-core benchmark numbers. Using the same CPU overclock settings, the Cinebench score is consistently in the 48.2-48.3K range enable versus 48.8-48.9K disabled. With the setting enabled, CPU-Z multi-thread is in the high 20K range (always under 21K) and single thread in the 950 range. Disabled, it jumps up to these values.

@tps3443 - try the above to see if it works for Ryzen the same. Leave tWR on Auto and use the formula above to control tWR using tWRPRE. With tWR set to Auto you should see the actual value displayed (48 in the above example) in ZenTimings. Tweaked a couple more settings to drop latency a bit more. I think I might be looking for another 8800 or 9000 CUDIMM kit in a few months. (I am seeing some indications that DDR5 prices might start to go down soon. Hope so.) For the interim, I think I am going to strip the chrome heatsinks off my new Corsair Vengeance 8800 CUDIMMs and put them in the second Apex on water and put these 8400 G.SKILL UDIMMs in the Unify-X (also on water) since it is not quite as good at memory overclocking as the Apex boards are.
