Hi there!

I own a 2570P and just read, that i could upgrade its CPU a bit. But i am not completely sure, which one to get to fit properly to the socket and the peripherals in general. Could someone help me out?



My laptop has the i5-3340M installed, chipset seems to be "7 Series/C216" or QM77 (according to the hardware manager, i dont know which one applies). BIOS version is V73 Rev. A. (just upgraded).



I was going with the i7-3740QM (or 3820QM) but will it fit the socket and work in general? Do i have to make any modifications to the BIOS (or other settings) to make it work properly?



Many thanks in advance! :)


EDIT: Ok, i found the top post... stupid me. I will go for a 3820QM, adjust it a tad with Throttlestop and mod the heatsink slightly with some copper pads. :)

I have tried to find a 820 G1 Keyboard, but there are no real offers (mostly unilluminated). And i have read here, that the connectors and physical appearance do not fit properly, so i will stick to night vision goggles ^^


EDIT2: Is there any fan  that is better then the stock one? I just thought about upgrading it too, but i cant find any information about the stock one to look for a better after market part...


EDIT3: So everything is on its way, i am going to glue a 2mm copper plate on the heatsink (over the complete surface, glue on the left and right side, thermal paste in the middle) and some copper shims near to the outlet.

I just wanted to add a custom boot logo but my HP_TOOLS partition is missing, And in addition i do not know which tool is necessary to recreate it. Some folks in the internet have asked the same question but the link to the HP support page is dead, so i am still clueless... Maybe someone has an image of an original driver disc around and could upload it somewhere, that would be great :)

So, the swap was successful, but I encountered a new problem. The i7-3840QM is recognized in the BIOS correctly as it is but windows shows it as i5-3340M. Is there anything I can do to correct this issue? I want the processor to work properly and that windows uses it as intended :)


EDIT: Nah, its okay now. Just a Windows update and two restarts and everything is ok. BTW the thermal management is now very good, even without additional software-modding (as suggested). No fan when booting up, long time no fan in idle and until now (downloaded/updated some games, high load on CPU [~70%] and SSD [up to 100%]) the fan has not reached max level (i observed that it has about 5 power levels, 0/25/50/75/100% and never got over 75%). So far i am very satisfied how the general result turned out :)

Just for Info, here is my HW-spec:

- i7-3820QM

- 16GB ram

- 504GB SSD

- maxed out heatsink

Everything else is standard.


For everyone interested, i installed a massive 2mm copper plate (in "+" shape, to maximize the contact surface to the aluminim block) on the heatsink (Arctic Silver MX-4 in the center and on the ribs, attached with EC360 thermal conductive silicone glue), 1x2mm copper shim (lower potion of the heatsink-pipe) and 1x1mm copper shim (upper potion) and 4x1,5mm copper shims on the heatsink. All copper shims are attached with the EC360 glue and have a size of 15mmx15mm. The "Heat-Vortex" (as i call it ^^) is coupled with the MX-4 thermal paste to the processor.


For being the very first time touching a processor, thermal paste and a heatsink myself i am very pleased with the result and that noching went wrong or shorted out :D

Enigma_2, could you post an image of the T-shaped heatsink. I am planning on upgrading. Regards from Unterfranken :]

      I upgraded my old laptop with i7-3632qm and its working fine, temps are ok but he wont boost. Lenovo g500s could be bought with i7-3632qm and it had same cooling as was 2020m so i dont think cooling is problem. Can i bios unlock? I cant acces advanced settings in bios. i need help

      We've had a stack of recurring questions from with problems getting a mPCIe eGPU working. This includes GPU-Z not reporting no clock details, error 10/43 or even not being detected at all. Overall it's more troublesome getting mPCIe working than say expresscard or Thunderbolt.
      Here's some common problems and some troubleshooting steps to correct them.
      Getting a black bootup screen, resolving error 10/43 or ACPI_BIOS_ERROR win bootup messages
      Here the BIOS doesn't know what to do when it sees an eGPU. So the solution is to not let the BIOS see it. Do that by setting the delays on the eGPU adapter (CTD/PTD - EXP GDC or CLKRUN/PERST# on PE4L/PE4C). Boot with eGPU adapter in the wifi slot into Setup 1.30 or Windows. Is the eGPU detected?
      I'll add that should error 43 continue AND you have a NVidia dGPU as well as NVidia eGPU then it's likely because of having the mobile NVidia and desktop NVidia drivers loaded simultaneously. Proceed to uninstall ALL your NVidia drivers, use "DDU" to clean NVidia registry entries and do a 'clean' install of the latest NVidia desktop driver.
      mPCIe port that hosted the wifi card disappears when connecting an eGPU in it's place
      Use the Setup1.30 PCIe Ports->enable to enable the missing port.
      eGPU does not get detected
      Overcome mPCIe whitelisting by booting with the wifi card and then hotswapping in the eGPU. That way the BIOS will enable the mPCIe port to work.
      1. Boot with wifi card into Windows, sleep system, swap wifi card for mPCIe eGPU adapter and ensure eGPU is powered on, resume system. Do a device manager scan in Windows. Is the eGPU detected?
      2. Boot with wifi card into Setup 1.30 *carefully* hotplug the eGPU adapter in place of wifi card. Hit F5 to rescan the PCIe bus. Is the eGPU detected?
      If this enables detection then avoid this tedious hotswapping by seeking a unwhitelisted modified BIOS for your system OR test the Setup 1.30's PCI ports->undo_whitesting feature.
      eGPU still not detected - set the PSU to be permanently on
      The latest EXP GDC and BPlus eGPU adapters try to manage the PSU to only power on after they detect a signal. This can cause a race condition where the eGPU isn't ready to go when the CLKRUN signal is asserted.
      Avoid this by jumpering the PSU so it's permanently on rather than being managed. Depending on the PSU you are using refer to the following doco on how to do that:
      eGPU still not detected - a non-standard mPCIe implementation by your vendor?
      PERST# mPCIe pin 22 may need to be isolated due to a non-standard implementation by your notebook vendor: http://forum.techinferno.com/enclosures-adapters/10812-pe4x-series-understanding-clkreq-perst-delay.html#post142689
      eGPU still not detected - faulty hardware?
      If you still don't get detection then test the video card and eGPU adapter in another machine to confirm neither is faulty.
      NVidia driver stops responding
      EXP GDC, PE4H 2.4 and PE4L 1.5 all use a socketted cable and therefore are not true Gen2 compatible device. This error indicates there was transmissions errors.
      The solution is either to get a better Gen2-compliant eGPU adapter such as PE4C V3.0 or PE4L 2.1b (both with soldered cable), or downgrade your link from Gen2 to Gen1 using BIOS options or Setup 1.30

      Required items:
      1.) Lenovo u310 (I have a Core i3 - Ivy Bridge, 8GB RAM)
      2.) 65CN99WW unwhitelisted.
      3.) eGPU (I used a EVGA GTX 750 Ti from another computer I had).
      4.) EXP GDC mPCIe Edition adapter (got from eBay - banggood seller).
      5.) ATX power supply (I used a 600W PSU from another computer I had).
      6.) USB wireless.
      7.) External monitor, keyboard, and mouse.
      1.) Obtain and install a unwhitelisted BIOS. If you are unable to obtain a unwhitelist BIOS, I think it might be possible to bypass it with Tech Inferno Fan's Setup 1.x (may need confirmation as I haven't used it myself yet.)
      2.) Shutdown computer and remove all USB devices, ethernet cables, power cables, card reader cards.
      3.) Remove mPCIe wireless card and detach antennas.
      4.) Attach EXP GDC external mPCIe cable to the former wireless slot and screw down.
      5.) Attach HDMI end of the mPCIe cable adapter to the EXP GDC device.
      6.) Attach graphics card to the EXP GDC device (I moved my laptop off the desk and onto the side shelf to make room on the desk for the monitor/keyboard/mouse).
      7.) Using the power cable adapters that came with the EXP GDC device, I hooked in my ATX power supply's 20 pin and CPU 4 pin cables. Then hooked the other end (8 pin) into the EXP GDC device. My EVGA 750 Ti also required that I use an additional PCIe power cable (6 pin) in the top of the card.
      8.) Then I attached my misc devices (HDMI monitor, USB keyboard/mouse/wireless adapter), and hooked in my PSU and powered it on (below is image of final product, also moved HDMI cable out of the way).

      9.) Power on your computer and let it install the standard VGA drivers and then install your drivers (I didn't have to go in the BIOS for any graphics settings, which it doesn't have anyways, nor did I have to disable iGPU in Device Manager before the card was added).
      Extra Info:
      I found that most games will play on med settings with about 45 FPS with this particular card.
      BDO: Upscale on - Anti Aliasing on - SSAO off - med settings.
      Skyrim: Med-High settings.
      Fallout 4: Med settings.

      Hello, A couple of days ago I got a new GPU but when I installed it into my computer I was unable to use it but now I know why. When checking the device manger I went into the events tab of my GPU when I went to view all events, I noticed an error it said " event 411 kernel PnP " and It also said Problem Status: 0xC01E0438. I believe this is why my GPU hasn't been working on my PC. If you know how to fix this problem or have info on how to fix this problem that would be greatly appreciated. I'm also using a EVGA NVIDIA GeForce GTX 1660.

      I'm having a problem where my PC is saying my eGPU is not usable, its detected in the Device Manager and it doesn't have the yellow triangle next to it. I cant use it games and the Nvidia Control Panel doesn't recognize it either. I'm using a EVGA NVIDIA Geforce GTX 1660. I'm using windows 10 and I tried DDU and reinstalling them and now I cant access the nvidia control panel. The GPU is not recognize on any other apps and I went on *********** and was unable to find my answer, Any help on how to fix this problem would be greatly appreciated.
