Hello everyone! I am looking for an answer to a problem I cannot find a solution to ... I purchased an Amd wx 4150 MXM GPU module su e bay to upgrade my HP 8570W Mobile Workstation which is currently equipped with a Fire Pro M4000. Once the new GPU has been installed, the PC screen no longer turns on but works only with external monitors connected via the docking station. The same happens once the drivers are updated! If I put the old card back on, the integrated monitor starts working again ... How can I fix it?
Over the last 10 years I've found laptops throttle the processor speed in order to keep fan noise down. I prefer the fan to run noisily, and the processor to run at full speed. I've developed tried and true mods for lappies and have demonstrated their effectiveness.
I have two Lenovo W541 laptop workstations with I7-4940MX processors and discrete nVidia graphics. On one I overhauled the cooling. Copper shim between CPU and hsf, AS5 on both sides. Shims between hsf and inductors near CPU and gpu, and shim on the gpu.
Used 'thinkpad_acpi' Linux kernel module to set fan to max speed. Ran mprime (prime95 for Linux) AND Unigine Heaven, alternating, to cure the AS5. Then ran mprime. Temps were slightly high. But laptop processors tend to run hot.
The I7-4940MX is a 3.1 GHz, 4.0GHz. Turbo processor. The modded machine ran at 3GHz. continuously running mprime, for weeks. The unmodded machine with the same max-fan-speed software tweak and stock thermal-interface material, throttled to 1.7GHz. at the same running temps.
Clearly, laptop manufacturers are robbing performance off the top, by inferior cooling hardware and materials. Granted, getting the cooling mod to all fit together correctly with smooth, flat surfaces requires hours of work and materials not normally found sitting around the house.
I normally do not mod the CPU die. I abrade copper surfaces down to 1500 grit paper, and then polish with scapings from a bar of buffing compound. Everything is done on 1/2" plate glass to maintain flatness. The final mirror polish is done with the compound granules on a clean, damp cloth.
Desktop processors mostly have slightly raised corners, so smoothness is not as much of concern. You're going to get thermal-interface compond completely covering the center of the processor. The ideal is to fill the microscopic gaps between the cpu die and the hsf, but where there is metal on metal, have it be.
Metal to metal provides 100s to 1,000s times the heat transfer of thermal paste. But, on a desktop, there are more effective cooling solutions than moving air. Most user are satisfied with their laptops, because the processor doesn't run full speed long enough to make a difference.
But I enjoy tweaking, and I do processor-intensive work, like batch editing 100s of large images, video rendering, security testing, password recovery, network testing; that are all severely compromised by poor, stock laptop cooling solutions.
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.
hello everyone, I have a MSI GT683R with a dying (pretty much dead actually) GTX560M in it.
I am looking to upgrade it to a new GPU, I have found a AMD Firepro M6100. (I first wanted to upgrade to a GTX970M, but that's too expensive for now... and corona is also making things difficult) I have already ordered a second heatsink to modify because I didn't want to modify the original heatsink it came with.
But, my question is. Does it even work in this system? I have heard of people getting it to work in the barebone variant of this system. But I am not sure if it would work in the 'fully loaded' variant.
Also, my games are mostly RAM/CPU dependent and I am looking for a little extra power in this system. I have found a I7-2860qm and I want to upgrade to 32GB of RAM, is it possible on this system? the sticker says 'max. 16GB of RAM' But I have feeling it says that due to the limitation of the cpu that's already on this system (I7-2630QM, 16GB RAM max.)
Hello everyone,, I need your expertise, I have a m17 r4, (2012) unlocked A15 bios thanks to Klem, it has a Gtx 675m in it now,
I would like to know the best GPU to upgrade to without losing a lot of the factory functions of the alienware laptop, like being able to use both VGA functions such as intel 4000, and the factory bios for the cooling of the GPU, I don't want to solely rely on the nvidia
As a full dedicated GPU, let me know what VGA card to get and what vbios to use, I will gladly donate beer to you for your help, or point me to a member on this forum who can help me,
Thanks, Shelby, Aka captcavy
