some of my computer specs are as follows:
GPU: RTX 2070
memory: 32 GB (forget the manufacturer/ clocks)
Dsanke bios mod
I recently bought a 1440p screen that is 120hz capable, but it does not allow me to select the 120hz option. I have checked numerous places and all of the websites say that this screen is 120hz enabled. I have the dsanke bios mod on my computer. I see people being able to use this screen's 120hz functionality, but I can't get it to work. Any suggestions? If you need any additional information about my laptop, I will be happy to provide info.
Hello everyone! First of all sorry if this isn't the correct forum to post this.
I bought a laptop few days ago. The laptop is Sager P150EM.
Gpu: amd hd 7970m
Os: windows 8.1 pro
So my problem is that everytime i install the amd driver after the intel driver my laptop freezes or gets a bsod or something that stops it from working. Any help would be appreciated. I saw somewhere something about vbios does this matter anywhere?
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.
Title sums it up.
TL;DR: we have a Clevo that runs a desktop CPU, one with those huge 82 Wh batteries. We remove the GPU and let it use the CPU's integrated graphics. How much time for the battery to go from 100 to 0? Is it comparable to an ultrabook's?
I'm theorizing a mobile set with a static eGPU and an upgradable CPU. Given a hypothetical user that needs fast processing on the go and long battery life while retaining very high degrees of mobility, but at home wants a powerful machine to run most games, I guess that would be their best bet. It would surely be more convenient to keep everything in the same disk. And even though the thing would be quite heavy to carry around, changing CPU would be more cost-efficient than changing an entire laptop. (Not sure if I'm right here, and also I'm not sure whether the motherboard in a Clevo would be replaceable when the new CPU needs a different socket, which is another reason why I'm asking here.)
If my above guesses aren't correct, then an ultrabook with Thunderbolt and without a dedicated GPU would be a better choice. If they are, then we would be carrying more weight in exchange of a more cost-efficient setup, which I think would be a fair tradeoff.
Also I am aware of the heating problems that these laptops suffer from, at least compared to a desktop setup. Would they be solved by moving the GPU out of the chassis, and instead plugging it with an eGPU dock via Thunderbolt port?
What do you think? Is it doable? If not, why?
I installed an NVIDIA Quadro P4000 Max-Q in a Clevo P750DM-G.
Device manager hardware ID shows:
I have done the standard inf file mod, then disabled driver enforcement as I have done successfully in the past, but it's not working this time. The install starts, then fails less than half way through. I have tried the DCH version, standard version, and studio versions and none of them will work. I am probably missing something. Could it be the result of the vBIOS?
