some time by now I flashed a custom Vbios (thank you Klem) on an Acer Predator 15 G9-591 and I started doing some tests about how far I could go overclocking the gtx 970m without running too hot. With the voltage up to 1150mV and something like 300 additional MHz for the core clock, in the strongest stress condition for both Gpu and Cpu ( i7-6700hq undervolted), the Gpu reaches a max temp of 85C (with some 86 spikes but never more than that).
Considering that soon I'm going to relid both Cpu and Gpu and clean everything in the internals (laptop is 4 years old) I think I'm going to have some additional heatroom.
I've already tested some further overclocking and I noticed that even if the temperatures remains under 93C (which is just for testing purposes, but after relidding temps could be nicer) graphical glitches occur and after some time most games crash. But my question is, could it be because of lack of power supply? The laptop charger provides 180W
Could there be an increase in overclock margins with a 230W psu or something like that? (Obviously with the same 19.5V output)
If anybody tried something like that on any laptop model, or knows the matter, I'd like to know
Hello all! Im posting this here in hope to receive some orientation or help regargind my egpu project.
I have my old and trusted Acer 5750G and I’m still using it everyday for work. I’m a photographer and it has worked quite well with some upgrades:
-Upgraded i5 to i7 2630qm.
-Upgraded ram, 8gb to 16 gb.
-Upgraded HD to SSD.
– I have the unlocked bios so I was able to set the mpci port as “hot pluggable” and I can also deactivate the dedicated nvidia 630m from the bios itself.
– I have bough this case [PCIe PCI-E EXP GDC External Laptop Video Card Dock / Laptop Docking Station (Mini PCI-E interface Version) ] that will arrive home in 10-15 days.
– I have ordered a wifi usb card.
I was thinking in getting a nvidia 1060 6gb and plug it to my old laptop using the mpci port. I ask for your advice and knoledge regarding this:
1- Is this a good card choice?
2- Will I face any problem with my setup or there is something important I should take into consideration?
3- Will software that uses CUDA (photoshop and premiere, for example) get reinforced with the new card?
4- How much processing power will get lost for the “small” port I will be using?
Thanks a lot again, and sorry for my english mistakes!!

I hope someone can help me out here.
I have an Acer Aspire E4-471g Laptop. Intel Core i5-4210U NVIDIA GeForce 820M 16gb DDR3 RAM 512GB SSD
I have an EXP GDC V8 Beast eGPU adapter. I use a power adapter to juice my eGPU by Dell Netzteil ADP-220AB B 12V 18A 220W P/N Y2515 REV A02
I have a Zotac GeForce GTX1050ti 4GB
The Problem:- I did the normal procedure, disable the eGPU. Took out the wifi and replace it with the mpcie cable.
Switch on the computer and I have a blank screen. No screen at all on the laptop screen nor in the external monitor.
Is there a best solution? I have seen the Setup 1.3 but I will do that if that is really the necessity.
I hope I'm not going to write off-topic;
I own an Acer Predator 15 (G951) notebook, and it never gave me problems before; I've never used the integrated audio jack port because I usually listen to music and other stuff through Bluetooth headphones, but few weeks ago I noticed that putting a jack connector in the jack port only deactivates the sound from the pc speakers, but the headphones don't appear in the "devices" section, and the sound coming out from the headphones is really faint and distorted (only if the system slider of sound is at the maximum level and the sound should be very noisy, when the level is lower I don't hear anything at all). Also, when I put a jack in the microphone jack port of the pc I hear the classic sounds of the jack which touches the pin connectors inside the port, but it doesn't happen with the headphones port. I tried almost everything: I changed a lot of headphones, both phone headphones with a single jack and pc headsets with two jacks (for the headphones and for the microphone) but every time it's the same. I installed and reinstalled a lot of different versions of the audio drivers, both from Acer and the productor (Realtek), and nothing changes, I also tried with Ubuntu and it's the same. What could be the cause, and can the problem be solved without any technic intervention? Anyway the warranty for my pc is still valid, but the assistance should be the very last resource (I should do a backup of everything and format and so on). And, the last question, I flashed a custom VBIOS some time ago, does this compromise the warranty? Should I really reflash the original VBIOS or it's not so likely they're going to check on this?
Thank you all for your attention!
