Settling In (2/7)



  1. Hi again, I've been out from home these weeks but a few days ago I managed to change the thermal paste along with a complete dust cleanup of fans. And the temperatures dropped of 23 Celsius for gpu and 21 for cpu, wow! I used Arctic mx-4 applying a tiny layer, the stock thermal paste was poured all over the place in absurd quantities and it was hard and crappy However, with 300 more mhz for core clock and 200 more for memory clock I have to set the voltage to 1175 (so one step over 1168) otherwise very few games such as gta V have graphical artifacts and minor glitches and in particular gta V crashes after some time -maybe something like 1h playing or less-. The same happens for FurMark Opengl. Anyway at 1175 temps are always around 69-70 C degress, so I guess it's good, right?
  2. Hello everyone, 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
  3. Well, it's the safest solution indeed. Thanks Sent from my HUAWEI CRR-L09 using Tapatalk
  4. Hi everyone, I own an Acer Predator 15 laptop and for some issues with the jack port and the SD reader I'm going to send it to recovery. I flashed a custom Vbios time ago, and even if the GPU works fine could it be a problem for the warranty? Should I reflash the original Vbios or having troubles with some technical inspections is a remote eventuality?
  5. Hi everyone, 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!
  6. Hi Klem, as you see I'm new to this forum and I posted something and waited for an eventual promotion to download that file but I'm still here. Please could you send it via PM? Thank you.
  7. Hi, maybe you could buy an external box for desktop gpus, although it's a very expensive buy . Do you know if there are good universal egpu boxes at the moment? I heard of something limited at one brand only
  8. Hi everyone! I found this forum looking for informations about modding on my pc, an Acer Predator 15. I wanted to replace the vbios with a custom one in order to unlock voltage controls and clock limits (my laptop has a gtx 970m 3gb) and I instantly received support from the modders, even if I haven't been promoted yet and I can't access to the files I need. Anyway I'm really interested in joining this community and I hope I'll feel good here, maybe one day I could be more useful to the other members. Thank you for the help.
  9. Well, but one more thing if I'm not getting boring Should I use the "m"nvflash version posted in this forum or it's the same? Because it seems that I'm unable to download it.
  10. Thank you for the attention! Here's the vbios VbiosAcerPredator15.rom
  11. Hi everyone and merry xmas, even if in late I own an Acer Predator 15, model G9-591, with a gtx 970m 3gb I searched here for a custom vbios to unlock voltages and clock limits, but i haven't found anything for my model. Can anyone help me? Thank you!
