Have that issue when the laptop (p771zm+980m) is only running from the battery.

 

It solves when I plug the AC PSU.

 

some older games make it louder too. might be related  with fps and power drainage.

 

I think it might be becasue the power consumption of 980m is beyond my power supply circuit or PSU , which I have 180w right now. I will try 230w later and see if it will be solved. ( But I heard there is a power limit in P151em.  )

Hey guys,

i just updated my P151em with a new 980m. Everything was okay but since couple days ago,  everytime I play 3d games , there is always some buzzing sound coming from my laptop. And when I go back to desktop, it will immediately stop. I found that many desktop 900 series cards have this issue but never heard about mobile version having this issue.

I am wondering if anyone else has the same issue with me and if this issue will damage my card. Thx!

Awesome! I'm surprised Eurocom did something. They have many stories of people submitting RMAs and hearing dead silence for over a month.

 

Grats on getting the card working.

Eurocom replied me the second day after I emailed them. And I paid 90 USD (100-10:  10 USD discount for student )for this support , which was good for me otherwise I would lose 600 USD on the card.  And we take couple hours to email each other , solving my issue. All in all , the experience was good for me and they replied very fast.  But my roblem is not solved perfectly since I have to modify drivers every time. He said something was wrong with hardward ID ( messed  up with g-sync and non g-sync . something like that. SO NEVER FLASH UNTIL YOU MAKE SURE THE TYPE OF YOUR 980M ) and he cant help me flash back to the right hardware ID only if he took out my chip and flashed it on aother socket, which was obviously impossible.  So that's it.  Anyway, it works so I think it is okay for me.

I'm surprised the v3 was required. It is not required, but helpful on you're P151EM's bigger brother, the P150EM. Maybe the Sandy Bridge CPU was a factor? It sounded like anything that had a DX10 codepath worked, while DX11 did not, so programs were polling the HD3000's capabilities instead of the 980m's capabilities. If you had an Ivy Bridge CPU this would be OK as the ondie HD4000 supported DX11. I never heard of anyone trying a 9x0m GPU on a P150EM with a Sandy Bridge, so maybe that system would be affected as well.

 

Anyways grats, enjoy the card.

Thx bro !

Ya. Thx for your help and kind  I hope my issue could help others with old models like 151em to solve some updated problems. 

I think the main key problem might be the  v3 bios of motherboard on em models. not sure if prema would release it later on.

No, 2.0 vs 3.0 is insignificant unless using SLI. The benefits you would get would be power savings and slightly higher performance. If you have a good Sandy Bridge CPU don't bother.

How much can prema vbios v2 increase the performance of 980m ? I flashed ZM OC v2 on it and got x4000 on graphic scores. Before that, I only have x3800 on graphic scores. But I didnt see big change. Is this normal ? or maybe I didnt flash the prema vbios correctly ?  

Another question: How to check if I have flash the prema v2 vbios correctly ?  

Really appreciate your help so far ! thx!

are you using a modified driver?

if so you need to disable driver signature enforcement.

Ya I am using modified driver. Driver signature enforcement doesnt have any effect actually, which will just pop out one window to ask if you want to continue duing setup. then click yes and it wont be any problem. I have solved my issue. Please check my other posts. Thx!

I paid Eurocom to get v3 bios and vbios for my 151em. And it finally works.

Qiweiyu11 is using a sandy bridge cpu. They only support 2.0.

 

I'm still leaning towards and OS reinstall to be required to fix this. Windows is garbage like that.

You are right. I am using Sandy bridge cpu on my 151em (  actually it is bga - > pga cpu , not official version :P) .  

Besides,  I have a question, if I change to Ivy bridge, will it improve the performance of my gpu ( pci-e 2.0 to 3.0 ?) ?

Thx!

I do...

When will u release it ? I am willing to purchase it to make 980m work correctly on my 151em.....zzzz

Yes it is normal for a modified vBIOS not to be read properly in a tweaker utility.

 

Another odd issue I see is that the card your only running on PCI-E 2.0

p151em is an old model, which can only support pci-e up tp 2.0 I think. My friend has 970m on it , which has the same issue.

But the main issue I have right now is I can' t run 3d mark 11 to test its performace.

That warning means nothing in your case. Flash away.

 

Have you tried reinstalling directx?

 

https://www.microsoft.com/en-us/download/details.aspx?id=8109

I tried it but 3dmark 11 still cant work correctly ( saying my adapter only supports D10 ).  I think the problem might lie in missing the switch function between two gpus. Therefoer, I still cant play witcher 3. In heroes of storm, 980m is not recognized ( only HD 3000 available ). Only dota2 can be played normally.  

Besides, I also flashed prema 980m-g 8g ZM v2 vbios on my card. But the problem still unchanged. 

Others seem good( Aero is back ).

Maybe I need the v3 bios to make it work normally ?

Another thing to be noted is I found Prema 's vbios cant be read by tweaker, which shows some errors in values.  I got it from Prema's blog. Is this normal ?

The card sounds ok. If it was bad you wouldn't be able to open the nvidia control panel.

Ya I can play dota2 without any problem and with better fps than 680m.  Btw, do you know if it is possible to pay for support from eurocom (because I heard that prema teamed with them to build v3 bios to make  all em models have 980m work correctly under any drivers), even though I didnt get this card from them.

Trying to work out on prema vbios v2. Does this mean I cant flash this vbios on my card ?

This is weird. On a P150EM the 980m would be running now.

 

Also weird is that Aero isn't running. The HD3000 supports that by itself, so the 980m shouldn't break that.

 

I'm out of ideas other than a full windows reinstall.

the aero is back now after I used the driver version before 360. 

Another thing is I cant flash prema vbios -g ZM on my 980M, It turns out error and closed automatically.

How to check my card is bricked or not ?

You tried a 358 driver with a .inf mod?

 

Also you enabled the 980m in the nvidia control panel?

ya I am using 358.50 version right now. I enable the 980m in the panel but nothing changed.

Just now, Khenglish said:

 

Are you using a Sandy Bridge CPU? The integrated graphics on those only supports DX10, so maybe you ran the render test on the iGPU and the 980m is not running?

you are right. the 980m seems not work at this driver version. so what should I do now ?

44 minutes ago, Khenglish said:

It should work in a P151EM. It works in the P150EM. The P151EM is off the same line as the P150EM, but is missing a power phase on the CPU and CPU overclocking support. GPU support is unchanged.

 

I'd try wiping all video drivers then running DDU. Install the intel driver, then the Nvidia driver. Upgrading GPUs on optimus/enduro systems sometimes has quirks, so there's likely some info leftover specific to the 680m that's messing up the 980m.

It still doesnt work correctly after wiping and reinstalling drivers. I can run render test on gpuz now but 3dmark 11 is not working as before, saying my card only support D10....

Thank you  for your help  anyway !

36x series drivers don't run correctly on the v2 BIOS. You need to step back to a 358 series driver.

tryed 358.59 , still the same problem...

read more about prema bios and stuff.

did u first get the 980m and then think about how 2 get it 2 work? .--.

I got it from my friend occationally so I didnt get the work prepared well but I checked the forum, saying it should work on 151em. 

Hi guys, 

I recently got one gtx 980M from my friend to replace my old 680M and I tried to put it into my P151em. However, the bios showed "empty" after installing it. With modding . inf , I successfully installed the driver 365.19.  But the info in gpu-z seems wired. 

1. no Directcompute !

2. cant run render test which is blank 

Besides, I cant use Aero on Win7 any more, saying it is not compatible with the driver.  And I also cant run 3dmark 11 ( saying not support Dx 11) and cant play witcher 3, which is a diaster....

I am using bios Prema 17 11 v2 .

Any method to make it normal so that I can install any driver I want ?

Thank you !!
