Hello,  

  

         I recently tried to overwrite my stock BIOS with the V2 PremaMod BIOS for my Clevo GTX 980M and the latest NVIDIA drivers( 373.06). Everything worked great until I enter a game, after about 1-2 minutes the laptop shuts down and the LED located on the power supply also turns off. My laptop is a Eurocom X3 ( P157SM) which originally came with a GTX 780M and I still use the 180W Power Supply from them, could this be the problem?

        I didn't try to overclock anything because I know 180w is simply not enough. If I use the stock BIOS again, everything works back again.

Did you use both the system and video BIOS mods?

Yes, I use them both. I have been using the prema mod BIOS for the system for a few years now with no issues...

Prema, I need help over here!

What does the "iout offset" and "iout slope" in the "CPU configuration" mean? what is iout?

 

I am trying to undervoltage my 4700MQ on P157SMA with PM V2 since the CPU temp runs to 90+ with FPUing or P95 small FFTing. I set CPU core voltage offset to -90 and it worked without crash for several months. A couple of days ago I set it to -120. (Further than that will result in bluescreens)

No bluescreens occur under the heavy tortures of P95 or LinX or AIDA64 FPU. However when I choose shutdown today after a day of microsoft office (several minutes ago before I start writing this) I suffered a blue screen. It seems that this CPU at low frequency does require a higher voltage than this.

I read the OC guides written by other Chinese OCers and it mentioned the LLC(load line caliberation). However I didn't find anything like this in the PM bios.

 

Any suggestions?

Those affect CPU TDP reporting. You can't undervolt in BIOS. If the system isn't stable it just means you've gone too far.

You can undervolt CPU in BIOS though. My model can too; I just don't because sometimes it resets.

I see. Not all Clevo models can undervolt in BIOS though, even with a Prema Mod. My P650SG flashed with PMv2 cannot.

 

Those two settings, IOUT Offset and IOUT Slope, don't affect voltage.

Now I've set it to -115 and wait for any bluescreens. (I've been working on a translation project with ms word all day long while waiting for it) If not, this is the final results of undervolt.

 

I rarely use my P157SMA on heavy work such as gaming though- I have a desktop PC with 4790K at 4.6 Ghz and a GTX 750 TI as a transition, where games are played. (Awaiting 2 NVIDIA GPUs of the large die size for the next generation gaming) The P157SMA acts mainly as a office handler and only in rare cases,the game handler. (Moving to parent's house on the annual spring festival) Light work is the most conditions it handle.

 

After all, the temp and workload of FPU and P95 FFT is too much and will never occur in 99%, if not 100% of its usage, isn't it? My desktop has the delided 4790K at 1.25V and 4.6Ghz with thermalright Le grand macho cooler along with a TY-143 fan. With FPU and P95 FFT the CPU ran up to 85C on temp and 168W on wattage, but I never see a temp higher than 65  and a wattage of over 100 in daily conditions even if I put a full load of BOINC WCG or any type of gaming on it. The temp torture of P95 or FPU seems useless and senseless.

Exactly. It is an unrealistic workload.

What would you use to test if an OC settings is successful? I am thinking of pulling the 4790K to 4.7 or 4.8 Ghz with higher voltage. However, the Le won't handle its wrath of heat under FPU or P95 FFT at that frequency. (That's about 180W on 4.7 Ghz FPU at 1.30V- will only last for 1 minute before overheat and CPU throttling)

What can we use to put a torture test to it without overheating and throttling?

PREMA I download the bios you have here for my GTX 580M,and the version with the oc .92v,i flash it and it give me a black screen with a flashing red line on the top of my screen....BUT,when I connect the DVI port from my P150HM laptop to my external screen it works!! The same goes for all the bios you have in the file including the stock one.....so I flashed back the one I had before, from the vga bios collection TECHPOERUP.so did I did any mistake on flashing the bios or something else?

Thanks!!


Flash a P170HM BIOS and use XTU v2.1. ;)



Depends on the MXM board revision.
Just try it, the wrong version won't flash either way. ;)

 

Guys a fast question,can the MSI GTX 670MX can work on a CLEVO P150HM laptop?Thanks!!!

I didn't prepare the first two software. However, with the P95 small FFT with AVX disabled, I got a CPU temp of 88C on P157SMA without downclocking- that's 58 watts on 3.4 Ghz!

That would assume that it simulates daily conditions. The CPU will be hot, but no downclocking will occur.

Although I noticed that most notebooks will disable CPU turbo boost while gaming (i.e. the dgpu is active). Don't know if prema broke this limit.

Recent Intel CPUs go ballistic when running AVX instructions, which is why disabling AVX reduces heat and power consumption so drastically.

Hi, 

Is Prema still modding BIOSes for Clevo devices?

 

There is an updated BIOS for the Clevo P157SM-A. The complete EC is different and is not compatible with the old Prema Mod BIOS. Without the latest BIOS Windows 8/10 will probably have some kind of compatibility issues and the latest Hotkey software won't work (So it's a kind of important update). 

 

I'm trying to contact Prema since April to get information if any update is planned or not, but never got any response. (https://biosmods.wordpress.com/p157sm-a/)

 

Is anybody still active modding the BIOS for the P157SM-A? Any hope for an update or at least some comment on this from Prema?

Ah. Makes sense I guess. Maybe it's all about the models. I know the SM & SM-A series could undervolt (at least with prema mod). I know the ZM/DM can as well. Didn't know the P6xxSx couldn't. Can the P6xxRx I wonder?

Hello folks i have a Clevo P771DM with a 980 GTX M 8 GB  (Intel GPU disabled by vendor) , bios does not allow fan control or overclocking

 

Im looking for a way to gain at least fan control for the gpu because the Control Software Center of Clevo frankly blows nuts.

(This is a 2500$ Machine and they provide literally no support , no bios updates and ship a software that is ultimatley garbage)

 

Basically i want to be able to control my gpu with third party tools such as MSI Afterburner (well at least the fan speeds)

 

Can this be done or is there one i can get for this already?

 

Regards, Sabre

I saw on some posts that there are some v3 prema bios. Is such the case for Clevo P157SM & GTX980M 8GB? I can't find them on prema's website. The reason I need it is because optimus won't work on my laptop with windows 10 64-bit. Thank you!

Hi there Folks,

 

I am currently having the following problem with my Clevo P170SM-A running Prema Bios with Win 8.1 64bit OS. The system was working fine when I last placed it into Hibernation. Now when I start the system I get the Prema Mod Splash screen with the words Resuming from Hibernation at the bottom, next appears the Raid Controller listing of the hard drives with the press CTRL-I to enter, following that the system just sits there. 

 

I am unable to enter the bios using F2 regardless of when I hit F2 or if I hit it like a crazy woodpecker during boot, nor am I able to use F8 to enter Safe Mode. I have tried the following things so far to correct the problem;

 

1. Removing the Boot Drive

2. Disconnecting Mains Power, removing the Battery and disconnecting the Bios Battery from the Mainboard. Then reconnecting the bios battery and power to try another boot.

3. Trying to boot from a USB stick does not work as I am unable to select alternative boot drives.

 

If anyone has any ideas how to solve this issue I would be grateful.

 

Thanks

If you need the Fan Control from this new EC 1.05.01 (i wrote some Posts before) then you can use Hotkey 3.08.20!
It works fine with PremaMod v2 and that Hotkey Version - you can use it like in the attached Picture :)

For NVMe support you don't have to flash the vBIOS. That's only for better performance.

Hi Sabre,

 

I have the P775DM3 with 1080 GTX GPU, and I was pissed by that fan noise as well.

Unfortunately, there seems to be no easy fix.

The GPU fans are not controlled via the GPU BIOS but via the embedded controller in the laptop (EC).

If you have a model from a Prema Premium Partner, you could try the Prema BIOS and EC firmware, which tunes the fan curves but doesn't give you control over the fan speed (correct me when I am wrong).

It is possible to control the fan speed via talking to the EC.

There is a Windows tool that was leaked by clevo I think some years ago and some guys reverse engineered that and implemented a fan control for Ubuntu for some models.

I modified that tool to provide automatic fan control for my p775dm3 running Linux - although I do not really like the solution. If the background process dies for some reason and is not restarted, the fans could be stuck at low speed and the system could run hot. I would prefer to implement a custom fan control in the EC, but I have no idea how to do so. Obviously, this is all highly experimental and can damage you hardware.

Anyway, I have summarized my findings here:

If you find a good way to control the fans, let me know :|

 

Cheers

      Hi Guys,
       
      Im looking to possibly get a new laptop, but was wondering what laptops you guys would suggest for gaming and that doesn't have hardware whitelisting so I can update my wifi card and other hardware in the future. I heard that Asus doesn't lock down there hardware with a white list. My current laptop, Lenovo Y500 Ideapad, has a white list and im not able to swap out the wifi card because of it. Let me know what you guys think.

      I dont know if this is the right forum to post this,  (but i need 5 posts for downloading a  vbios)
       
      so my questions are these, thank you in advance for reading
       
      I have bought a laptop with a half melted 880M GPU Im assuming the person did not keep an eye on temps,
      so i went and replaced the card, it runs fine, (alright) but still, I remember modding my VBIOS for my 680 GTX back in the day, and it was fine, exceptionally faster, 
      and im looking for that 60 fps LOCK, like i got on my 680 after modding the vbios, 
       
      I did increase the voltage on the card to 1.212 I believe, from 1.114 ,
       
      anyway I considering modding the cooling system as well for this laptop, because it definitely lacks cooling 
      My plan is to put another laptop fan (where the HDD1 bay is in the Alienware 17) bcause I removed that hdd it was constantly at 57c which is bad
      even think it suffered some damage as speeds on it for specific games and tasks are pretty long, and it stays at 100% some times, which is weird, but it still works, so im using it.lol
       
      , but in the meantime, I turned the laptop upside down, plugged in the HDMI cable, and now im blasting a ROOM fan at it, which is definitely helping with temps
      before I would try to throttle the gpu speed at 77C, or 73C depending on the game or even saying screw it, I dont want throttling, and putting the throttle point to 83C,
      I use SPEEDFAN , and it helps keep the laptop relativly cool, except when the gpu is under full load,  putting my hand on it is ridiculously hot, so, with the fan on it, its not going above 70,
      and taking a LONG time to get up there, 
      i am playing metro last light at around 60C at 60+ fps, where as before my temps were shooting upto 80 and it would hit the throttle point, so  seeing as how this is a 120 HZ laptop, I rather not push it, since the card is not capable (and if it is, the cooling sure isnt)
       
      the plan is to put the fan inside the HDD1 bay, and POSSIBLY  daisey chain it to either A) the cpu fan header, or  B ) the gpu fan hjeader, 
       
      QUESTION:
      not sure which "rails" the power for these comes from, would it be able to handle another fan???
      it seems like a legit idea, seeing as how the rear of the heatsink has NO heat dissipation at all. which is the part that melted offcausing the old  card to die in the first place.
      basically the thermal pads look like they gunked the card and it was unfixable, I have a post to it on the Alienware Forum, which i could link later,
       
      is it a good idea, and will the VBIOS WORK with my 880M (DELL) from a clevo, (now in an alienware) im assuming they are compatible, as long as they are dell.
      also would I be able to get a Y adapter for the inside of a laptop fan, that would be AMAZING, i know they sell them for Desktops.
      Thanks
