Hi everyone, I have an unusual request. I have an i7-3940xm in my M17xr4 and it's difficult to keep cool. I have already done the m14x fan mod and I'm using Thermal Grizzly Kryonaut thermal compound... it's just not enough. The CPU is constantly being throttled (my bios settings in a11 unlocked are set to throttle it 85 C) when under load, and it will sometimes see temperatures in the mid to high 90s. The maximum operating temperature is rated at 105C, and I have a thermal shutdown set in bios for 100C, which it hasn't yet reached (but it gets scary close). Even when throttled, it's still an upgrade and runs better then the stock 3630qm, but I don't wan't it to throttle all of the time. I know I could underclock it, but what's the point of having an upgraded CPU if you're just going to downclock it to similar specs as the original (baring cache, of course). At idle, by the way, it jumps around mid 50s to high 60s.
Anyway, to keep it cool, I want to try using a peltier cooler. They're thermoelectric ceramic devices of which one side gets hot and the other gets cold when an electric current goes through them, for those who didn't already know. I figure I can sandwich it between my cpu and the heatsink and try to help keep the cpu's temps a little more reasonable. I have one of a workable size which can withstand temps of up to 135C, and I've done the math with it's specs so that it hopefully knocks 25ish degrees off while at full load and not overheat the peltier doing so. This leads me to my question/request; I need to know if anyone would know a place on the motherboard which supplies voltage when the laptop is running, but not when it's off, whether or not the charger/battery is connected? I have found a few good sources on the MB which can withstand the drain, but they're always hot, even when the laptop is off. I have a multimeter and have been probing, but I don't want to disassemble half the laptop and attempt running it in pieces to verify a good source. If no one knows off hand or has any idea, does anyone know of any schematics or files which exist which contain voltage information of various contacts on the m17x r4 motherboard?
I know this is a strange request and most will not be able to assist, but before taking it all the way apart to probe around I thought I would at least ask. I'll make a write-up on how it's done and how well it works if it's successful, as well as a controller circuit if necessary using a teensy 2.0 or something.
I'm debating whether or not to replace the thermal paste in my Lenovo y510p. I've started overclocking a bit, and I have an external fan, but I would like to not have to run the fan as fast because it is a little loud. I have been reading a bit about different thermal pastes, and I'm wondering if there is even a big difference between stock thermal paste, and something like the liquid metal from thermal grizzly. It sounds like it'd work better, but I don't want to fall for a good marketing scheme. If anyone has experience with this and has or hasn't seen big differences, your input would be greatly appreciated.
Thanks in advance!
Thanks for this incredible forum, I hope I will learn a lot from the gurus !
I am trying to make my eGpu MSI GT X970 work on my laptop with K1100M integrated GPU.
This are my specs:
CPU: 2.7GHz Intel Core i7-4800MQ (quad-core, 6MB cache, up to 3.7GHz with Turbo Boost) PSU : ??? Graphics: NVIDIA Quadro K1100M / Intel HD Graphics 4600 RAM: 32 GB Storage: 1TB
I got a V8.0 EXP GDC Laptop External Independent Video Card Dock with the express card version ( I am not really hw savy) and I am looking for a good psu to power my MSI GTX 970 4G
Could you kindly suggest a good PSU that i could use to power this GPU ? I am also willing to do as many experiments needed
Thanks for reading my post
I recently bought the new Toshiba RC100 m.2 2242 NVMe SSD for my Lenovo Y510p which has an m.2 port in it.
After installation the SSD wasn't showing up in my BIOS and also not on my OS Win 10 disk management. So I did a bit of research and installed mod BIOS for my Y510p by following the steps in the link: ( https://www.techinferno.com/index.php?/forums/topic/3546-lenovo-y410p-y510p-unlocked-bios-wlan-whitelist-mod-vbios-mod/ )
There are a lot more options in the BIOS menu now.
Even after doing the mod it's not showing up. The SSD works on my friend's "new 2017 dell gaming laptop" which has m.2 ssd support in it. I don't know what exactly to configure my BIOS to make it work. I've just done some hit-and-trial configs which have eventually failed.
If someone can help solve it Pleasee!!
P.S. : I can share all the available options available in the BIOS if required.
I put on a eGpu setup after quite a bit struggle 2 years ago and I used play games just fine. After a while I sold my graphics card gtx 970.
Now since 2 days I am trying to put the eGpu setup back again this time with a Gtx 770.
I couldn't understand the problem. I can shut my dGpu off with diy 1.30 setup. ( usb booted)
And my laptop sees gtx 770 along with my igpu Intel HD graphics 4000.
After driver installation when I try to play a game laptop is tring to use iGpu instead of Egpu. (tried to delete and install driver few times)
With MSI afterburner I can see eGpu is %0 all the time.
Can it be power problem cause graphic cards fans ( Msi gtx 770 twinfrost ) are working all the time they dont stop.
Or what else can it be.
