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 want upgrade my GPU but I have doubts about wath to get:
FIREPRO M6100 --> 150EUR
GTX 680M --> 250EUR
I think that the best choice is the GTX680M but the price is more expensive but I don´t know if the performance&compatibility difference between them worth it.
Not sure whats holding me back. Maybe I need an unlocked bios flash. old card was a GTX 680m 4GB. New Card is an GTX 880m 8gb. The card fits, shows up in device manager originally as a microsoft generic adapter. After modding inf in the nvmii.inf file I was able to get past the compatibility scan, however the driver fails to install and now the card is shown as an unknown device. Im sure its BIOS, but Im not sure what Bios to grab. I downloaded the latest bios from MSI and flashed. No problems there. im currently on E16F3IMS.50X. tried modding and older driver from nvidia, but the same problem occurs. passes scan, fails the driver install. doing it manually by pointing to the inf fails too with different errors each time. At my whits end, please point me in the right direction.

I have a big problem-> I need to undervolt my GPU (MSI 7970M@DELL_BIOS).
I am using this vBIOS: https://www.techpowerup.com/vgabios/132831/dell-hd7970m-2048-120629
Stock VDDC on this GPU is 1.050V and when I changing this one to 0.975 in VBE7 it is ok-> I can save it and flash it. Computer succesfully restarts but when I check modded settings the VDDC is still on 1.050V
I checked if the VBE7 seriously saving the VDDC to vBIOS but it is ok. I have no idead what i need to UV this card (i know it's possible...)
Everything is changing (GPU, MEM MHz) but VDDC can't change.
Please help me ;-)
Please help ! I Have 150SM-A laptop with PREMAMOD bios. Everything was ok but I hanged CPU and RING voltage to add 100mV and ovveride to 50mV. Now laptop does not boot up only blank screen is present. I tried to reset bios by removing battery from laptop and from motherboard for few minutes. Unfortunatelly after this nothing changed. Laptop switchen on for few seconds then turns of and turns on again in loop. The screen is dark.What can I do ?
