Whats missing P570WM

Recommended Posts

Nothing really.

1 - Seems to be a USB connector for camera/3d display (probably for different laptop models)

2 - Seems to be some kind of debugging port. Lot's of motherboards have them, sometimes unpopulated (with no connector)

3 - Seems like a connector for a bluetooth module judging by location and the BT label on the cable. Probably USB as well

4 - Third WI-FI antenna. Only used with 3-antenna WI-FI modules.

You're not missing anything. Different laptop models often share the same motherboard, so some models will have certain ports populated, others not.

      Hi guys, I am the proud owner of a Clevo p775dm3-g notebook purchased from azom.systems (authorized Clevo reseller in India, Model rebranded as Azom Legion-17.3 inches). Here are my specs:

      Core i7 7700 (non-K version): undervolted by 110 mv and turbo boost disabled in BIOS- machine uses prema mod BIOS.
      GTX 1080: undervolted by 100 mv on all frequency steps using MSI afterburner voltage/frequency curve editor. clocks are untouched.
      16 GB DDR4: Cant remember clocks.
      1440p 120 Hz screen: No tinkering done to refresh rate.

      CPU has been delidded and repaste has been done on both CPU/GPU dies with gallium based TIM-Coolaboratory liquid ultra if I recall correctly.

      My issue is GPU hitting max temp limit of 90 degrees while playing DOOM and framerate drops from 110 avg to mid 60s-70s with horrible stuttering- this is thermal throttling for sure.

      System was running beautifully after repaste at 86 degrees max/ 77 degrees average at 100 percent fan speed. A month later I decided to see how much further I could push the system and ended up undervolting the CPU/GPU and RAM even further. The RAM undervolting part didnt work as well as I'd hoped, and I ended up resetting the BIOS to undo everything and reapply the previous setting (-110 for CPU with turbo boost disabled.) 

      I noticed that immediately after BIOS reset, both my CPU and GPU temps were 5-10 degrees higher even with the undervolt/underclock applied. Also, I think the fans were a bit louder before I reset the BIOS which leads me to believe that for some reason the fans are now capped at 80% max fan speed. There doesnt seem to be a fan speed selector in the BIOS or anywhere else so I cant say for sure whether this is a fan related issue or something else.Before the reset I could override the BIOS setting and set the fans to 100% by pressing fn+1, could I have done something to that setting after resetting the BIOS ? I dont think I have damaged the CPU or GPU as temps are holding fairly steady at 90-91 degrees and laptop doesn't shut down while gaming.

      If I have overlooked something or if anyone reading this has any solution help would be greatly appreciated.
      All settings/drivers/windows version/app version are exactly the same before and after BIOS reset.

      Hi all,
       
      It has been a while since I did anything to my laptop (Clevo P670RG-G) and since I recently got a VR Headset I wish I could overclock my GPU a little. So far the NVidia software (on windows) doesn't allow me to overclock it (the linux sort of allows, which some custom Xorg options) so I decided to give a try modding the vbios.
       
      I read all sorts of issues / guides about it, and it seens that the hardware topology (where the vbios is stored and how things are connected) changes from machine to machine.
       
      What I know about my laptop is that it has two VBios, one for Hybrid Mode and one for Discrete Mode. I'm currently running the discrete mode.
       
      I dumped my VBios using GPU-z and opened up in Maxwell II Bios Tweaker. Everything seens fine so far.
       
      So I have few questions about it:
       
      - There is a way to just unlock the VBios to show the overclocking options in NVidia software? (That way I dont need to reflash to change clocks)
      - I can just flash this GPU-z dump to my VBios?
      - If I brick my GPU, that GPU-z dumped image is the raw SPI image, so if I managed to physically access the VBios, I can just reflash over it?
      - I saw some people saying that I might need as well to flash the main laptop bios as well, is that really needed?
       
      Thanks!

      Hey everyone!  After lots of searching it looks like this is the go-to place for laptop mods online, so I figured this would be the best place to ask something like this.
       
      I picked up a Dell E6530 for basically scrap value, and I love the thing.  Runs Xubuntu great, battery is halfway decent, and I can play 99% of the games I own on it.  My friend on the other hand picked up an E6440 with its silver-ish finish along the back.  As much as I love my 6530 I've gotta say, that thing looks great.
       
      To get to the point now, I was wondering if it's possible for me to polish the top of the lid on my 6530 to have a more silver finish like that (or maybe even a mirror finish if I sand it down with a fine enough grit).  Really what I want to know is if the dark grey part of the lid is actually metal.  I can't seem to get a definitive answer online, and I tried the magnet test on it and it wasn't magnetic at all.  This doesn't necessarily mean it's not metal though, as aluminum isn't magnetic but is obviously a sandable/polishable metal.  One source said the laptop has anodized aluminum parts on it, but they didn't specify whether it was something internal or external.
       
      Can anyone here provide me some insight?  If the grey part is definitely a metal and not a plastic, I think I'm gonna give it a try.  As stated before I got this thing for scrap value, so if in the end it doesn't work out I'm not gonna cry over it or anything.  Still though, I'd rather not run into this blind.  If this is indeed possible though and I can accomplish what I want with a decent looking result, I'll post up some pictures with the method I used for others to do as well.
       
      Thanks in advance!

      There are several threads on requesting BIOS modifications here on T | I but I thought another one wouldn't hurt.
       
            Your request should look like:
      Brand Model Type of modification(For example: Unlocked, added support, Logo, microcode, ME firmware etc  
      I'll respond as soon as I have time as I'm also currently working on other projects(Requests by PM is also ok)
      If anyone else have the knowledge and time feel free to respond to requests
