***Prema Mod Alienware 18 970M / 980M SLI Performance vBIOS***

Can you upload each GPU vbios?

 

sure here !

Spoiler: 980M VBIOS

http://www.filedropper.com/vbios980m

let me know if this fixes the second fan also for you !

 

Its stock DELL vBIOS for 980M 8Gb

 

Any one can you post a 3DMark Firestrike with this, Curious on how it performs vs a Stock Clevo and Prema vBIOS 980Ms, thanks !

 

Single or dual 980m?

 

Single GPU for comparison , SLI score would also be sweet.

 

using dell stock bios or nvidia bios ? Right now I have nvidia bios on my 980m.

 

nVidia Bios stock :

Thanks but I don't have 3DM11 to just compare the GPU no's , could you do a Firestrike score ? Oh that's Nvidia BIOS, I wanted to see how the Dell's stock does too..

My card shipped with Clevo vBIOS from woodz, he said it won't throttle as in custom vBIOS maybe but I flashed Prema vBIOS since day 1 and here are my scores with 2 drivers but I'm using 362.00 because the 364.51 gave me some weird throttling in Dota2 could be power plans related but no compromises allowed...

 

I'll do firestrike when I get home.

Only 1215MHz or is that a 3DMark reporting error?

Temps?

I thought 970/980M could do more than 1200MHz...

...well maybe 1200MHz is around the limit of 980M, here they only got away with 1264 or so: http://www.anandtech.com/show/9087/clevo-p750zm-gtx-980m-overclocking-investigated/2

P.S. But yeah 10500 GPU is a great score, that's about what I'm seeing with 680M SLI overclocked to their limit at 1.025V (+225 / 400 as well). I would love to have the performance of both my cards on one card as there are so many good games that have poor or no SLI support and I could really benefit from more than 2GB of VRAM.

aside from my M18x R2 and I have an M17x R2 (i7 920xm @ 3.5GHz, ATI 5870M SLI) and would love to actually put the 980M SLI in my M18x and the 680M SLI in my M17x (for redundancy's sake, theft or failure a possibility). So what is the current state of 980M in the M18x R2?

 

Highest temp on gpu was 57 Celsius. I think turbo boost is 1261mhz. On nVidia inspector, i can go only max +135mhz. Is there a way to unlock the " Min and Max " settings on nVidia Inspector ?

 

57C High in Firestrike is very impressive, how about during sustained periods of gaming? Assuming you have a Clevo variant, are you able to control the fan speed with Hwinfo64 without issue?

Also, I added more pertinent information to my last post after you responded and may have missed.

 

@vulcan78 , I'm not using hwinfo at all. Just the stock fan control. Oh , I do have a modded laptop cooler that is blowing up from the bottom. fan blowing so hard , it got that 8x11 paper standing up. Check the link on the bottom. You might like the MOD.

I'll play some COD and see what kinda temp it gets up to.

So far 980m is not fully supported yet in Legacy mode. Two members is working on the Bios ATM to see if it can actually happen. Besides the " Legacy " issue for the 980m , it runs great in the m18x-R2.

Edited: and thermal compound is Artic Silver 5 : Idles at 35 Celsius

 

I hope everyone had a nice Easter holiday. Just a bit of good news... @Prema has a new Alienware 18 980M vBIOS v2 available. He just posted it today.

Come and get it! https://biosmods.wordpress.com/aw18/

If it works good for you, please remember to say thanks to Prema with a few greenbacks to let him know you mean it.

 

whats the rar password ?

 

premamod.com or biosmods.wordpress.com

 

Does the V2 still have the voltage increase to 1.067?

 

Is it safe to use the AW18 Prema vBIOS on Alienware 17 ?

I wonder about the GPU fan control with this vBIOS (+Compal EC), with the current vBIOS if I use compal EC the fan1, fan2 controls are interlinked but fan2 won't rotate (Maxwell problem)..have to use Dell EC with default but max fans on gaming and benches.

 

On new prema vBIOS V2 2nd fan work fine on my system

 

Can somebody please check the voltage under load using GPU-Z

 

Does this work in the M18x R2 or is it AW 18 only?

 

1.0620 V

 

I think it is intended for the 18. Whether it works well on the M18xR2 would be a matter of trial and error. It should be safe to flash, even if it does not produce good results with the M18xR2. Maybe @Prema can say something about it.

 

Thanks for that. Will pass on this for now....not a fan of voltage increase.

 

man my cards run so hot on these Vbioses !

 

For almost half of all sold 980M 1.062v is the stock voltage. For 20% this is already an undervolt as they use 1.075v and more. Only if your ASIC is in the higher third it'll use less.
If I would use less voltage then the mod won't run for many at all at default settings without crashing their system.

That's how they run without throttle...if you want it cooler use the temp slider. You can force it to run @ 50c (showing 49c is an NVIDIA Inspector misinterpretation (bug) of the actual value).

 

There is no way that is the case. On stock dell vBIOS my 980Ms on full load do not exceed 1.000V
I will check again this afternoon when I get home to make sure I'm not spewing BS here, but I noticed a temp drop and fairly positive it was a voltage decrease too when I went from your v1.1.1 back to stock Dell vBIOS.

 

There is only a single ASIC which use 1v and that is 85% and up.

 

Like I said, I will run a bench tonight with GPU-Z monitoring the voltage and clocks on stock vBIOS. I'm running a piss poor asic of 68%-69% on both cards, but I've logged the voltage when running ARK before, and never exceeded 1.000V

I will post results later tonight

 

That 1v must have been the svl7 vBIOS, stock vBIOS has fixed ASIC registers...
The only other way to see a stock vBIOS to run that low, on regular ASIC, is when it massively voltage throttled (throttle lowers clocks and voltage).

For your systems the Clevo base will produce better results. This is only for AW18 and won't fix the FANs on the R2 etc...

 

So I was mistaken, it runs at 1.0560V at full speed, but it is still less than the 1.062V of your vBIOS. We REALLY need to figure out how to enable that damn nvidia inspector slider so we can do some proper tuning here.

 

The Mod uses 1.062, which in your case should be exactly the stock voltage of your lower ASIC card. (If you see 1.067v on the other card then your other cards stock voltage is even one step higher than average).
Your higher ASIC card is now overvolted by 0.006v...

I have made a few tests and found that even with on-the-fly undervolting fully unlocked it'll override the voltage slider again after a second to set it back to it's base-line.

I can make vBIOS which starts at a lower baseline like e.g 1v (aka fixed undervolt), but this forced undervolt would not work for many as it is too low and simply crashes their cards.
Even systems that used to run stable @ 1v with the svl7 version are now crashing with newer driver as they put higher load on the components than they used to aka running hotter than the pre-360 driver.

 

Thanks for the reply and for the work you've put into getting 980M to be backward compatible. I'm cautiously interested swapping out the 680M SLI in my M18xR2 for a single 980M (Clevo), what is the current situation with 980M in the R2?

Thanks again.

 

The R2 and other AW should not throttle using the Clevo based mod unless OCed.

 

I think a 1.00V baseline should be released, at person's own risk though. It is easy to overvolt, not easy to undervolt. I wonder why the slider is busted..

 

If you lower the base voltage it will likely be unstable and require lowering the core clock and produce below expected stock performance, which is already a problem on Alienware. I am puzzled about one thing... Why do you want to cripple performance if the temps are OK? Most people with 980M want to go exactly the opposite direction, so you may be the odd man out on this one. On a given model of CPU or GPU using more voltage means more performance potential and using less voltage mean less performance potential. I just had @Prema provide me with a custom 980M vBIOS mod with higher voltage limits.

 

Spoiler

 

@Prema , How an I get my 980m to be able to get to those settings ?

 

Believe me you don't want to...it'll probably fry your card and system...
It was really just more a humorous way to underline @Mr. Fox philosophy of more is better...

 

cheers Prema

 

Hello Prema

Glad you got the final Bios out. Thanks again for all of your work!!

 

I have no intention of lowering the core clock or memory clock. I just wanted to reduce voltage if possible while retaining stock clock. I've never been a fan of overvolting CPUs or GPUs, and I always target max performance on stock or undervolted values. My 4940MX is a actually a superb chip, will run 4.0Ghz 4 core at a nice low voltage of 1.0970V-1.1010V vs the absurd 1.280V it originally demanded. I do the same with my 780Ms, bump up the clocks by 50MHz a piece and drop the voltage by 12.5mV with great results.

 

@Zero989

Looks like you are VR ready!

THX again for testing!

 

Just also added the v2 Prema Mod for GTX970M!

Everyone can thank @Mr. Fox for using a GTX970M in his AW...

As always, ENJOY!

 

May i buy soon Clevo 2x970M for my M18xR2,will it be possible undervolting 970M's?
I would like make really very cool system
Thanks a lot your awesome work!

 

I hope you have better luck than I do. The 970M I have seems to be junk... cannot handle any kind of meaningful overclock... very pathetic with black screen crap unless I leave it stock.

 

I would like OC some times (970M optimal environment can +500MHz on core) ,some nice benchmark results ,but if don't work it's not huge wrong for me,i never using any OC when play games.Stock clocks may will +30% Graphics performance,enough for me

 

980M single can be flashed with prema vbios for aw18?
