Aw m18x R2 Dual 980m SLI upgrade!!

I had to populate all the mosfets on the top of my card to prevent 1.2v from shutting off.

 

Oh BOY!
I know my father in law can easily do that for me hehehe, where would I be able to buy those mosfets?
So I would guess then if I don't populate the empty spots I will be sticking around that 1.16v max and it seems then the extra mosfet on some might have some impact at higher voltages as well.

One more ? I see some cards are blue and some green, some from Canada and some China ... are they all pretty much the same from what you have seen?
(on a side note powenotebooks is one of the 2 places I am considering getting my card from) I take what is said here as being unrelated to that unless you guys can put the mosfets in before shipment hahaha
and I LOVE your activity here Meaker! I have been seeing your great posts since I got myself a 680m and my next notebook will most certainly come from you guys (hard to let go of the m18x r2) love it !

oh boy I think populating mosfets is gonna be my second project besides a sub zero water chiller for the desktop hehehe

PEG Mode is suitable or possible with a SLI M18X-R2? Does anyone tried this? I want myyyyy cards noooooow haha

 

Oh my this thread is still active. I can see that now many lads upgradin Aws to 980M. I hope that stupid throttlin issue sort out. Well now im Alienwareless Slightly off topic but now im building desktop, wanted to share my new gaming system.

Bit Overkill isn't it with 3 Titan X? Your not even running a 4K monitor lol..

 

Yummy anyway ...

 

They should work with the 980m/970m....I'd be sticking with the triple pipe heatsinks though

 

lol yeah, actually just wanted pure performance I got LG 34um95 which is resolution around 3K. I think got to wait for good 4K IPS display.

 

Is the 34um95 a high refresh rate monitor? I've got myself a lowly desktop 980 and it's not overkill on a 1080p 144hz display.. Gonna get me another.

 

It's a 60Hz monitor.. nothing to spectacular... I saw one of these Widescreen monitors and I rather have a standard 16:9 one..

There is overkill and in your case absurd Overkill @peter... 3 Titan X's is a bit too much for this monitor... Even a 3K/4K monitor would do fine with 2 of them..

 

I don't think I'd ever bother going with tri-sli, I think it causes more problems than it solves (game compatibility issues, case heat, power draw, (perhaps more micro stuttering?)); I'd stick to normal sli with 2 cards, and then overvolt/overclock them if I wanted more performance.

 

It helps if you have a LOT of pixels to drive, say 3x 4k monitors.

 

Hello,
I have a chance to get a good deal on dual 980ms. I currently have m18x r2 with 780ms sli.

I keep hearing nightmare about 980ms sli in the m18x r2... Can anyone clarify for me? Do these cards work in the r2 without too much trouble? The last thing I want is spend money and get nothing but headaches.

Thanks

 

You really wanna have someone reply who owns that setup, but from what I've read there are some GPU throttling problems, especially when the GPUs are overclocked. I think you need to use Win8 and UEFI boot too. Just putting this out here so you don't just jump on buying those 980Ms - but hopefully you'll hear from Mr. Fox or other owners to get more accurate confirmation.

 

@Juang1985 - 980M has some issues due to NVIDIA doing some extremely retarded engineering crippling tactics to it, but it is awesome enough that it is understandable that people would be interested in upgrading. However, installed in the M18xR2 it sucked bad enough that I eventually just gave up and spent another $2,000 getting a Clevo P570WM set up so I would have a good place to use my 980M SLI without any kind of throttling crap and other inexcusable drama taking place. The throttling was absolutely horrible, to the point of rendering the machine unusable for gaming or benching much of the time. Using a stock vBIOS and running stock clocks it often worked OK, slightly better than 780M SLI, but using a stock vBIOS and not overclocking is definitely not my idea of a good time... it was downright unacceptable.

Having to use pure UEFI boot and not being able to use Windows 7 also blows really bad. I've always had a preference for Windows 7, running my machines in a dual boot configuration and having the ability to use both operating systems in the scenarios where each does better than the other. But, being forced to run Windows 8 exclusively kind of tainted my perspective and turned my preference for 7 closer to something resembling a bitter hatred of 8 because of its more limited functionality and performance impairments.

I went back to 780M SLI in my M18xR2 and I still love that machine as much as I did before 980M was released. My recommendation would be to skip the 980M upgrade, cross your fingers, and hope that "1080M" (or whatever the 980M successor is called) functions properly in the M18xR1/R2/18. @j95 has some tweaked drivers that may cure the throttling problems with 980M SLI, but I don't know if anyone has tried it with an M18xR2 to find out if it works effectively for SLI. I haven't and don't plan to at this point. Even if the throttling problems are fixed with his tweaked drivers, that won't fix the problems with the BIOS not allowing VGA boot support, being forced to use pure UEFI/GOP, having to stop using Windows 7 and not being able to use Legacy boot. 980M will not even POST in the M18xR1 or M17xR3 because of Maxwell's VGA/Legacy boot incompatibility issues with the Alienware BIOS firmware. Because of these serious functionality limitations, vBIOS flashing is a gigantic pain in the butt with the M18xR2 (requires disassembling and flashing one GPU at a time) and it is not even possible with the Alienware 18 (requires an unlocked BIOS, which is not available for the 18) because there is no UEFI version of NVFLASH that works for 980M.

 

Thanks Mr Fox,

That's all i needed to hear.
On the subject on Nvidia crippling the vedeo cards to avoid people from overclocking, I am currently having a strange isssue with throttilng with my 780m SLI setup. I do have the SLV7 Vbios and temperatures are not the issue since i monitor them all the time never go above 85c cpu and 75c gpu.
its been a couple of drivers (since battlefield hardline driver i believe ) that i cant no longer overclock my 780Ms Sli without throttling.... have you experience anything like this on ur m18x r2???(u probably dont use it much since u got urself a new beast)
basically it throttles down to 2d clocks dandomly during gaming over and over.

Not sure if is a problem with my laptop of just nvidia crippled me too, Just havent seen many complaints on here about it so im a bit paranoid my cards/mobo could possibly going bad.
Keep in mind if i DONT overlcock everything works perfect. as soon as i touch the clocks a little i start having throttling problems.

I already tried replacing my Powerbrick thinking starting to die, it made no difference.

Currently on 350.12 Version of drivers (for GTA5)

thanks Mr Fox

 

Yes, absolutely with that horrible 350.12 GTA V driver... severe throttling doing ordinary gameplay at stock clock speeds in some games, and always extremely severe when overclocking. That driver is your problem. It does EXACTLY the same throttling crap to my 780M SLI and single 780M machines (all three of them). I cleaned everything up with DDU, reinstalled my 345.20 desktop driver mod again and that problem instantly goes away. NVIDIA is getting to the point that they suck almost as much as AMD does.

I posted about that 350.12 driver problem in another thread already and GeForce Community has tons of negative feedback about this lousy driver. It is causing all sorts of issues for a lot of folks. Mysteriously, for some it works OK. And, I'm using 350.12 for 980M SLI and it's working fine there, so go figure... weird that it affects 780M like this. I smell a rat with what they are tinkering with on drivers. It smells like a green rat, and I'm not too happy about it. I think we probably should buckle up and prepare for a bumpy ride with NVIDIA's driver team Nazis as they continue to experiment with customer control tactics and end user manipulation shenanigans.

 

Okay that makes me feel better... I a way i guess... now i know is not my laptop.
so if you wanna play the latest games like Battlefield hardline & GTA 5 how do you do it??? with the 345.20 i dont think they support SLI for these new games does it?

is there a way around it?

 

I'm not playing either of those games, so I don't have to worry about it. You could likely modify the profiles to add the code from 350.12 to an older driver using the Geforce 3D Profile Manager tool or NVIDIA Inspector and have it work as well as 350.12 does in SLI.

I have read through most of the reply in this thread, and the conclusion that i have is upgrading to 980m sli on m18x r2 is not worth the hassle. But would the use of proper driver prevent the throttling? Im for one that rarely overclock my gpus (Because i have 7970m cf atm, overclocking it is like giving it a death sentence XD), would the stock clock of 980m sli to be enough to work around with when playing graphic demanding games? One last question i have is, if i only play my games at 1920x1080, is the upgrade worth it?
Sorry for my poor English.

 

Do your games suffer at 1080p at the moment?

 

I pretty much have no problem running most games at high or even ultra, but i am not really sure my 7970m cf are able to handle upcoming games later this year, especially witcher 3 and battlefront at the graphic that i desire. And one thing that bugs me is after i activate v-sync, sometimes its kinda hard to maintain 60 fps, im not sure it is because crossfire causes it or its because the nature of v-sync.

 

Why not wait and see? I think you will still be pretty good.

 

It seems like my 7970m cf is about to die when i start seeing black screen when booting up the system, and sometimes the screen goes black for few second. It could be the sign for me to change my gpu. This is my second set of 7970ms and my first set didnt last very long.

 

Unfortunately, that is not an uncommon situation. Back in the day, 7970M CrossFire was a crazy powerful setup for a laptop, and it's still fairly stout. It is truly a shame that it has proven to be such an unreliable product for so many people. I had four defective ones as well. The 6970M and 6990M cards that I had before 7970M were also buggy and unreliable.

 

That is the sad truth indeed,i started using Hwinfo when i installed my second set, i have it on whenever i turn on my laptop, the temp are pretty stable under 70c, this temp seems very good to me while my first set were constantly hitting 80c(probably due to poor temp management of the alienware's system temp control). So is Nvidia prove to be more reliable than amd? And would the upgrade to 980m sli from 7970m cf worth it? And how stable is the 980m sli in gaming if using the right driver?

 

Yes, NVIDIA has been far more reliable for me for the past several generations of GPUs. Better in every way. Sad, 'cause I used to be a huge ATI fan, but things started going south when AMD took the reigns from them. While I do believe in miracles, it would take a miraculous product release (best stock performance, plus crazy show-stopping overclockability and acceptable product reliability) for me to ever entertain the notion of buying another AMD product. I definitely won't be an early adopter of anything bearing their brand name any more. The risk is far too huge based on my own string of unpleasant experiences.

As noted previously in this and other threads, 980M MXM upgrades do not function properly in an Alienware. Your best upgrade option is 780M SLI. With an unlocked vBIOS, 780M overclocks like a banshee and will literally run circles around 7970M CrossFire, as does 680M SLI with an unlocked vBIOS. Either of these GPUs will smoke your 7970M CrossFire setup, but especially 780M SLI.

If you want 980M SLI, buying a Clevo with a good quality unlocked and socketed CPU is really your only decent option. That's why you see one in my signature... Eurocom Panther 5, aka Clevo P570WM. The MSI 980M SLI option is a jokebook... equipped with a pathetic BGA-mounted low-TDP turd CPU, so it cannot be taken seriously as a performance enthusiast machine.

 

Thanks Mr.Fox for this informative reply, i am convinced to get a new set of 780m for my alienware, but after i went to check the price, it is pretty much the same price as the 980m. On Rjtech, the 780m is even more expensive than 980m and on Eurocom the price of 780m and 980m are pretty much identical(and i dont trust ebay anymore, so i am not gonna shop on ebay)
I cant really make a decision now since getting a pair of 780ms could be a bigger investment over getting a pair of 980ms.

 

If I was you I'd sell the M18xR1 while the 7970Ms still function. Then take the extra money that you would have used to buy the 980M's, add that to your money from your M18xR1 sale, and then buy a P570WM that includes 980M sli. That's a better long term investment I think.

 

This is a good idea. I had already blown a $1,500 wad of cash on a 980M SLI upgrade with optimism that we would get all the kinks ironed out. When it became clear that wasn't going to happen, I had to decide whether to sell them as used parts at a loss or buy something I could use them in. In 20/20 hindsight, my best options would have been (a) do nothing and continue enjoying my amazing M18xR2, or (b) buy a new P570WM with 980M SLI factory installed. The Maxwell incompatibility crap caught us all off guard because GPU upgrades have never been problematic in the past for M18xR1/R2 owners. I partially blame Alienware for this, but that may be unfair. Nothing changed with the machine... it was NVIDIA that screwed things up with changes in Maxwell firmware architecture. That's not Alienware's fault, except for the fact that they did not remain engaged with NVIDIA to keep them from doing something stupid that would mess things up for their existing customers. There may be a conspiracy behind that, but I have nothing to base that on. Probably just lack of engagement and influence on their part. Whatever the case may be, we're the ones getting screwed by both of them. Screwed by Alienware primarily because all they sell now is crippled mainstream BGA garbage. There is nothing worth buying from them any more. If I had any interest is buying garbage, I could buy mainstream BGA "gamer trash" laptops for less from another vendor.

 

Hello @Mr. Fox Can I know your view on these in terms of Performance, Longevity & Quality ??

First : If it is P377SM-A with 980M SLI and an MX CPU how does it fare against Clevo P570WM with 980M SLI..
Second : P377SM-A 780M SLI vs M18x R2 780M SLI, love this Alienware M18x R2 but the current situation is making the future is unpredicatable...

Considering the ClevoP377SM-A because it has all SATA III while the M18x R2 and P570WM are limited to only 2 SATA III.

Thanks !!

 

@Ashtrix - I cannot speak to build quality because I have not handled one, but I seriously considered the P377SM-A as an option at one point. Based on how I intended to use the machine, gathering feedback from multiple P377SM-A owners, feedback from Eurocom, and observations from benchmarks and user experiences posted in our community, I made a conscientious decision to avoid the P377SM-A and go with the P570WM. My decision was largely based on thermal management problems. Alienware has always delivered superior cooling. Haswell is enough of a blast furnace that any compromise on CPU cooling is a big problem regardless of what machine the CPU gets installed in. The P377SM-A does not appear to be properly equipped to handle the kind of CPU overclocking that I absolutely require. This is as important to me as GPU overclocking and I cannot separate the two in my own mind or prioritize one over the other. Take either one away, and the machine in question is no longer an acceptable option to me.

That said, even the P570WM struggles a little bit with thermal management. I'm sold on the machine itself, and love the hexacore desktop CPU. I probably would have selected the P570WM for the CPU alone, but the thermal management challenges the P377SM-A has is what made the choice easiest. Long story short, I have no regrets and love my P570WM. Given a chance for a do-over, I would buy it again. However, both models are clearly lacking in terms of cooling system efficiency and BIOS overclocking options that I have been so spoiled with as an Alienware owner. But, alas, that's history now with Alienware. Those are no longer Alienware advantages if you are shopping for something new.

Edit: Oops, I forgot to address one of your questions. I can only answer based on my own perspective. I think everyone would prefer all SATA-3 6.0GB/s speeds on all ports. Faster is always better, but I have to consider what difference it is going to make in the grand scheme of things. As long as my OS is using those SATA-3 ports, I'm a happy camper. In normal everyday use, an SSD running on a SATA-2 3.0GB/s port doesn't have a meaningful impact on how fast my machines feels. The difference is largely indiscernible. Running at 3.0GB/s doesn't do anything to hurt 99% of my CPU/GPU-centric benchmark scores, or adversely affect my gameplay experience, so it is much lower on my list of priorities.

 

However awesome the Panther may be, I would get the P377-SM-A.... Haswell runs hot but with the modifications of using a P370EM heatsink and some good paste you'll be fine.. It's also a bit more futureproof IMO too.. P570WM only works with 980M because of Prema although the P370 series can run the 980Ms even with stock BIOS etc although you need inf mod... I can definetly say SATA 3 is noticeable from SATA II...

 

Out of curiousity @Mr. Fox that you've said about BIOS features, but isn't full custom Prema MOD for Clevo's not enough, does it lack any features that M18x R2 SVL7 BIOS has ??
Thanks !!

 

There can be features missing even in a fully unlocked bios that are simply not coded in.

 

Is there any change.org petition going on right now to sign in for trying to change Dellienware mind about this fiasco?
I don't understand why in this world they don't want to fix the issue. Their reputation will increase like speed of light.
I'm very disappointed with the brand since last year.

https://twitter.com/nikos4life/status/591424213766012928

 

Yes, there are quite a few missing options in the Clevo BIOS. CPU thermal management, various sensors, and some finite controls for the CPU, memory configuration options and other things unrelated to overclocking are notably absent. XTU takes care of about 75% of the settings that are needed for overclocking, but it's closer to the the same limitations using XTU with the Alienware 17/18 without an unlocked BIOS. The Alienware 18 does not overclock with stability nearly as well as the M18xR1/R2 with a plethora of settings for finite control. The firmware environment is also totally different. The AMI/Aptio BIOS is nowhere nearly as robust as InsydeH2O BIOS. That is a two-edged sword, because the robust features are what allowed Dell/Alienware to lock us out of the Haswell 17r1 and AW 18 BIOS with the Gestapo-grade Secure Flash feces. The new BGA Alienware systems have an AMI/Aptio BIOS like the Clevo and they can be unlocked. Unfortunately, with the lousy BGA CPUs they are using, there is just not much point in bothering to unlock a BIOS with a crippled CPU welded to the motherboard.

To be clear, @Prema has done a truly AMAZING job with Clevo BIOS mods. Without Prema's mods, the P570WM would not perform anywhere close to how well it does with them. To Meaker's point, Prema cannot unlock a feature that does not exist. What @Prema and @svl7 primarily do with their BIOS mods is expose hidden settings so we can access and use them. Clevo would need to add features to the BIOS that do not exist for Prema to expose them. Thanks to Prema, we probably have access to far more options than what Clevo would like for us to have.

 

AW 980M 'OCing' Throttling FIXED!.. AW GTX 900M Throttling FIX

 

I think it's fixed:
FireStrike:
+135 MHz/+400 MHz +25 mV
i7 3920XM @ 4.6GHz
14445
No throttling at all.
More than 340W during the test. I've recorded a video showing that. What's next?
How I can flash my cards to test with svl7 or Premas mod?
@j95 if this is the end to the throttling problem I guess it's safe now to say We love you! I will donate to you as soon as I can. You deserve everybody respect.

 

I know you already saw this, but it was in a different thread. I am quoting it here in case others that seek an answer to the same question have not seen the reply.

 

Perfect! I let the link to the other post if you do not mind.
¿Best upgrades for M18X-R2? [CPU - GPU - RAM - Cooling] Best for the buck.

 

Maybe I have done something wrong with matching the P-states or I have a bad/dodgy driver installation (I used 350.12 from nvidia's site with J95's modded inf), but its not working for me
First run +150/400 clocks didn't throttle but usage did.
Second run after a restart with the same clocks resulted in a very similar score but the clocks jumped about, lowest was 1126mhz on the core.
Using premas 980m OC vbios
I'd like to mess about with it more but I have mid sems and assignment due

 

Did you flash Prema's vbios v1.1 or v1.0? Correct bios is v1.1 , 1.0 won't work.
Driver installation use nv_dispi.inf from here AW GTX 900M Throttling FIX not P1 sig mod.
P0/P1 matching both core & memory, don't mess w/ voltage offset, Let the driver handle this. First find out max stable OC uisng stock 1.068v. This is for 'everyday use'/Gaming.

Extreme OC, Reset the card first (obligatory step before any serious OCing Kepler & Maxwell cards)-> enter the BIOS -> OC options -> BCLK re-apply current settings -> "apply settings immediately" -> "apply settings permanently after reboot" -> F10 -> auto-shutdown -> done. *New Trick*...

Like OCing w/ 1.068v you'll need to match P1/P0 the same way, just set the proper voltage offset instead.

... follow the steps above, donate to Prema >first<...

 

ok thats the issue then, I have v1 which must be v1.0 hopefully I can try tonight with 1.1

 

I have been watching this thread for a while now, and I'm so happy that we have people like J95 and Prema . I was at the verge of deciding whether or not I'd trade this laptop for a Sager, but even with +135 overclock without throttling, I think the M18x R2 is here to stay for a long time
Now I just need to gather some buck to replace my 660M with a pair of 980M's haha.
Kudos Guys!

 

I'm going to make a list to try to simplify as much as I can the whole process:

Feel free to copy the list and edit it if I miss any step.

2. Get @@j95's modded drivers (Download HERE) (Make a donation to him - HERE <- need your link @@j95 please ).
3. Remove the secondary GPU and turn on the laptop.
4. Change the BIOS to SG mode and UEFI with Legacy Option ROM.
5. Disable the 980M in Device Manager (this is required with Maxwell).
6. Flash the primary GPU, reboot and re-enable the GPU in Device Manager (Be patient, because UEFI with Legacy Option ROM flashing takes a bit longer sometimes).
6.1. After flashing, test or bench if you wish using a USB keyboard.
7. Shut down your laptop. Disconnect all power.
8. Put the secondary GPU in the primary slot.
9. No need to separate the heatsinks. *
10. Disable the GPU in Device Manager (this is required with Maxwell).
11. Flash the secondary GPU, reboot and re-enable the GPU in Device Manager (Be patient, because UEFI with Legacy Option ROM flashing takes a bit longer sometimes).
12. BEFORE REASSEMBLY, put the BIOS back to PEG mode with pure UEFI (no Legacy Option ROM). **
13. Access startup settings. Next, click or tap the Advanced options tile. Select the Startup Settings tile on the Advanced options screen.
13. Reboot into safe mode (option 4)
14. Remove previous drivers with DDU, and access again to startup settings. Next, click or tap the Advanced options tile. Select the Startup Settings tile on the Advanced options screen.
15. On the Startup Settings screen, tap the F7 or 7 key on your keyboard to select the “Disable driver signature enforcement” option.
16. Install GeForce 350.12 WHQL -> Install using nv_dispi.inf from HERE.
17. NV Inspector -> Match P0/P1 stock clocks first -> Run Valley Benchmark then find out how much the card will hold w/ 1.068v , finally update settings. Don't mess w/ voltage offset including undervolting, only when OCing.
18. Do some benchmark (3DMark FireStrike 1.1, 3DMark 11, 3DMark Vantage...)

*Lay the heat sink radiator on top of the chassis above the VGA/HDMI port. It will make a solid connection in the PCIe slot for flashing. Since there is no air being pushed through the radiator, it will get too hot if you try to use it this way, but it will be fine just for flashing.

**If you forget to do this you will have to remove the secondary GPU or the machine will fail to POST with 8 beeps. Once the BIOS is correctly set, put everything back the way it is supposed to be and you're ready to go.

Note:
The only thing I do not understand is how I am supposed to boot into windows 7. I would like to do all this without having to format my current system. Is it possible that someone share an image (ISO or so) that let me boot up and flash? I hope you understand what I am talking about.
