    Yes.

    It will work. It absolutely has to.

    It will work because its just a 7970m with a different BIOS that includes a boost function.
    It will still throttle if combined with an extreme processor.

    Most likely it will work. It's basically a 7970m with a different vbios.

    As for throttling, unless they lowered the stock voltage, then yes it probably will still throttle.

    As long as its MXM 3.0B form factor and not more than 100W, it should work.

    Apparently it features 1.075V. So I won't upgrade. It must be exactly the same card as the 7970M.

    Best to wait for the next gen. Perhaps with the 8990M.

    It would be worth to try but will probable be pretty close to the 7970m performance.

    The M15x cannot handle the 7970M at 1.075V. It shuts off.

    If the new card features this at stock then it would have to be undervolted to work in the M15x making it a standard 7970M. The 7970M can hit 950-1050mhz at 1.05V and up to 1500mhz on the memory. If you have the 7970M this upgrade would not be a wise one. If you don't have it then still best to wait for the next gen or get a 7970M as it will be cheaper.

    Unfortunately I think the beloved m15x has hit the end of the road with the 7970, unless something miraculous happens next gen.........and even then you're looking at something that will definitely be held back by the cpu.

    Says who? This generation cards offer great performance with lower power consumption (Kepler). I imagine the gtx 760m and 770m will both work in m15x with inf mods.

    My 7970m didn't shut off in the m15x at 1.075v. I ran it at 1.1v once to benchmark it, worse case scenario was throttling.

    Saya guys with 3610qm. The 920xm OCed is no more of a bottleneck than your cpu :D Also GPUs might end up sharing some of the workload with the CPU. That seems to be AMD and Nvidia:s goal.

    Anyways I fully intend to push my 920xm to the very end thus surpassing the performance of even the 3610qm. How about 25x across all cores at 100% load :thumbsup:

    Look at Tomb Raider for example. It hardly uses any cpu usage whatsoever!
    I mean less than 10% of my 940XM!

    You are right. I meant 1.1V. I gamed at 1ghz /1.5ghz and 1.1V in Crysis 3 with cpu at 23x across all cores. The game ran beautifully for 5 mins!

    Hmm for me I only ran 3DMark11 and used the computer normally so I'm not sure about running 1.1v on the long run.

    I don't see why the 8970M would use 1.075v when the 7970M uses 1.050v. You'd think as tech is refined (easier to make on the 28nm process) it would use less power. Maybe it'll downvolt lower than the 7970M.

    Apparently it is the same card. It might be slightly better binned and therefore OC better otherwise not much difference other than the increased vram to 4GB. That in itself is a good feature.

    Still though I can't think it a good upgrade from a 7970M

    Here's hoping it works, Would love to test it out and seeing if it can be OC'ed. People over at Tech Inferno suggested that the ram does not OC well in the 8970M though :/

    Okay, well the 8970M works, it just causes my system to keep a specific fan speed and does not change. It stays at 4483rpm the whole time. When I try to run 3dmark11, it shuts down every time due to overheating. This is with stock settings and my cpu not even overclocked. Is there anything I can do to fix the fan control on my M15x?

    You have got pads and screws already?

    You can manually control the fans using Hwinfo. Otherwise no there isn't. It can't be a dell 8970m you should return it and find one that is if you want the fans working as they should.

    A trick to try however is to boot up and run the program then set the fans to a specific speed and then quit the program. If you do this it trips the fans back to system controlled. Sometimes when I boot up my gpu fan is also running fast I simply do this and the fan goes back to normal.

    There some seconds delay before fans resume per system control. Which hopefully for you will be normal speeds

    I tried using MSI Afterburner, HWInfo nothing works. I can't control my fan speeds. I think the EC or the vBios is locking it. It constantly sits at 4493RPM for some reason. I don't know what to do! The fans work properly for the CPU. I Adjusted the cpu fan manually to a higher setting then it went into auto control. No matter what I do, the GPU fan does not change in speed for nothing. I set it to a higher level and it goes up then back to its usual setting. It does not go lower or higher than what it does when I first turn on the machine. There is no point in the GPU fan going at 4000+ RPM when the GPU is sitting at 30-35C... I checked the number on the chip and it looks like it is an 8970M but for some reason the temps get too high and the fan does not adjust speeds to compensate. The machine runs beautifully when it is idle or I'm browsing the web. The moment it clocks to 3D mode....it gets too hot and shuts off.I have latest AW 09 bios. I have a $300 paperweight.

    That 4000+ RPM is the maximum. What temp does it reach when it clocks to 3D mode and how fast? Maybe the automatic fan control does not work, and I have a hunch that the card is not positioned properly. Maybe there is not enough pressure on the die. With fans on max it should take a while to reach the shutdown temperature so something is definitely wrong.

    If you don't like the fast fan speed, just make a manual table in hwinfo with temps and fan speeds and enable that at startup.

    The temps hit 75C+ within 1-2 minutes of starting Bioshock infinite. I am making sure the chip is securely fastened to the heatsink. One thing I do notice though is that the GPU voltage hits 1.075V once the 3D clocks kick in. I can't seem to change it. I did not want it to run at that voltage, I just popped the card in, installed the latest AMD drivers and tested it with 3dmark. Hell I even tried to modify the vBios to use lower voltages, the card didn't take it even though it was programmed successfully. Even after a flash, the card is still using 1.075V and still uses max fan speed. I am okay with the fan speed at the max, just as long as the GPU does not heat up too much to the point where the machine shuts off on me. :/ I can always buy a new GPU fan. The GPU itself costs a pretty penny.

    Isn't 1.075V overvolted? Maybe the card was overvolted from the vbios before you bought it. Any luck with software undervolting?

    No, I tried using Atiflash and VBE7 to flash the bios, and no go. Voltage still hits 1.075V. I feel like I am stuck. It's like I am sure if the card was put back to its original voltage, it would not get so hot. When it idle's it stays around 30-35C. :/

    Hmm at 1.075V the temps are not too surprising! Especially as the cooling is stock.

    Perhaps save your vbios using gpuz and ask if SVL 7 can look at it for you. He might be able to sort out the voltage. Perhaps even undervolt it a little.

    It's sad that I got it this way. I would understand if I modified the vBios to do that....but this is just ridiculous. The worst part is that because I don't have the right Alienware machine, the seller does not want to refund the money back to me. Even though that the card is operating at a higher than stock voltage right out of the box. I sent my bios to SVL7 and hopefully he will get back to me. I don't want to get stuck with a card that does not work right. When I ran Bioshock Infinite, the game looked amazing and it was smooth! Just wish temps would be normal. I would rather undervolt it to 1.0V because SVL7 said that is what his run's at.

    Well I bought a card from the same guy and will most likely run into the same issues. Luckily for us we can always sell the 8970m or trade someone for a 7970m. I don't have y card yet but I will report back when I receive it. hopefully it's a fluke but at least there is hope for you.

    Hopefully your card works. I don't want to deal with this. Honestly, I prefer to keep the 8970M because of the increased ram. I found an offer for a 7970M at $300 on ebay. If SVL7 is not able to fix the bios, I am going to buy the 7970M and just sell the 8970M. I just want a working laptop at this point.

    I feel for you. Yeah the m15x is just an extra toy for me. I bought it on a whim. it'll be a lot easier to carry around than my m18x. I hope you get it figured out.

    I hope so too. Any info I find I will pass this way as well. I just feel like If I can somehow reduce the voltage, it will be perfect! Here's hoping to SVL7's quick response!

    He will reply but he is a busy guy give him a few days.

    I am contemplating switching cards with you for fun but the fan might get annoying! I could at least have a go getting it to work right and then send it back.

    All right, I assumed given he didn't respond in a while that he was busy. I guess I will be patient. But I have something to look forward to...as my previous thoughts concluded...for some strange reason my 8970M last night decided to run at 850/1250 @ 1.025V. I turned the stealth mode on and off a few times (I''m not sure that is exactly what did it...) and it went into that speed and voltage. In the process, I finally learned how to control the fans! I used HWInfo and set it to custom auto for the CPU and GPU. The key is to set the respin time to a decent setting and hit minimize all so it constantly runs in the background. I tried this before but didn't hit minimize all then wondered why it didn't control the fans anymore haha!

    Given the fact that it chose to play at 1.025V, I decided to take that opportunity to test the card. BOY this thing FLIES! Bioshock Infinite was maxed out and was solid 60+FPS for 2+ hours. Temps ranged from 65C-80C. It never went above 80C because at that point the fan control hit max RPM. GPU usage didn't hit higher than 60%. I think if there is more GPU usage though, it will get hotter. This opportunity confirms my theory that if the card can run at 1.0V or max 1.025V, it will be stable in my M15x! I don't care if the core and memory clocks are lower than 900/1350Mhz. It's pretty fast at 850/1250Mhz. The main thing is getting this card to use less voltage. I will try to figure out how to cool the GPU better without modding the machine like crazy, because the whole point of it being a laptop is for some portability. I will look into cooling methods too, I just want to get this card working without it. I will worry about faster clocks later.

    Thank you! I am so excited. I will try it again today to see if I can get it to stay at 1.025V. I would rather prefer a vBios that runs at 1.0V or max 1.025V so I don't have to worry about monitoring voltages. Or at least a modified vBios that will allow me to edit the voltages manually. It seems like voltages are locked in the vBios of this card. I went to the hardware store close to me again and had them order the screws. I can find them online via ebay too but they charge a ridiculous amount of money for 4 screws! I should be getting my 16GB set of 1600Mhz ram tomorrow too so hopefully that works and I should be done with hardware! Just have to make sure the voltages are within a safe limit on my GPU. :./

    Good news. Those clocks are practically stock 7970M (850/1200) albeit with a small memory bump!

    I think 900mhz is the "boost" mode perhaps you cannot change those clocks only the base 3D clocks which are 850/1250mhz.

    The 7970M really benefits from having the memory OCed. Even at stock clocks big gains are seen up to and over 1400mhz. Once you figure out how OC the memory first and see where your limits are.

    Anyways you can definitely do better than 1.025V. At 0.975V my core is stable at 850mhz and on stock cooling won't go above 75C under 100% load. The reason your load in low at 60% is because your CPU is not OCed enough. Put it to 3-3.2ghz and let the gpu stetch it's legs.

    I re-installed FC3 last night. I will see how it does with the cpu clocks! Also Iam going to bump the memory up to 1350mhz. Memory voltage cannot be controlled only core voltage. So even when undervolted you can play with the memory and considering the vram will pull more or less the same power therefore you may as well play away that is if you have your temperatures under control.

    4GB vram is kinda overkill on the 8970M. By the same you saturate 2GB you will be pushing this cards to it's limits at a high OC. I found Crysis 3 maxed the 2GB but this was at 950/1450mhz at very high settings and some low AA. If pushed higher AA the card would have run out of horsepower to play properly before utlising more vram.

    Okay, I did some testing. I managed to get the voltage to stay at 1.025V. I will need SVL7's help to hard code the voltage into the bios though. I had to enable the unofficial overclocking mode without power play support and add a profile with custom clock settings to get it to use the 850/1250 @ 1.025V. The thing is, If I lower or raise the clock or memory speeds, it automatically uses 1.075V. So in order to keep it at 1.025V, I need to keep it at 850/1250. You can now understand why I need SVL7's help at this point.

    I am fine with the 7970M speeds for now, until I can get lower voltage from the vBios level. I need to really learn how to use Throttle Stop effectively to really OC my CPU. The thing I am afraid of is if I overclock the CPU, then the GPU usage will get higher, resulting in higher temps. I just don't want my pc to keep shutting off automatically till I can get the voltages and vBios settings sorted out.

    I am happy that the card actually works and I can do some moderate gaming, so long as I can keep temps low. I know 4GB VRam is overkill, But I didn't get to choose how much VRam was put into my card. ;) It's nice to have, but I bought the 8970M due to it's price and future proof ability. I am afraid to OC the CPU and let the GPU go full power until I can get voltages straight. Until then, its low GPU usage and low clocks. :./

    Good luck on testing the memory and CPU clock! Let us know how it goes!

    Not testing just for playing I know it is stable. I know exactly what my gpu can do :d this is just a simple gaming undervolt overclock

    850/1250 is fine IMO. The voltage is what needs tweaking. Be patient he will be able to help you. Just be sure to thank him he has done ALOT of work for the m15x community and others too.

    I'm fine with 850/1250 too. So long as the voltages get lower to support cooler temps. I will donate to SVL7 if he can help me out with my vBios issue. It would be the best to get this card to work the way I know it can work! I am also going to mod the cover for the bottom so I can get more airflow too. I already bought a new notebook cooler with 2x120mm fans pointed towards the machine. I will cut the plastic off the back cover next. I'm thinking mesh would be nice so I don't have to worry about making it portable while allowing more airflow directly to the CPU/GPU.

    Remove all drivers from before. First, uninstall all Amd drivers (Catalyst), Then use the Display Driver uninstaller here: Display Driver Uninstaller Download version 12.9.4.0 Be sure to use that program in safe mode! After it restarts, download the 14.6 beta drivers from AMD. Let me know how your temps are and what vBios version you have.

    Well I got my adapter sorted out and everything is installed. My Gpu is at 32c at idle and 0.825 v but when it ramps up to 900/1250 it jumps up to 1.1v and then it takes a swan dive. Any luck undervolting?

    That's great news you got it to work. It seems like you and me have the same problem. You're idle temps are good but when it's on full load does it hit 1.075V or 1.10V? I have not heard from SVL7 in regards to a vBios that is undervolted. What vBios version and what subvendor is your card from? You may need to disable AMD PowerPlay and use non boost speeds and see what voltages the card uses at base clocks. I added copper heatsinks to the GPU and it still gets too hot. Does your M15x shut off from heat/temps? What temps does it reach up to?

    The thing is, while my card is using base clocks, once the GPU usage hits over 75%+...the temps reach 85C+ which triggers an auto shut down once it hits 87C. I can play games if I use base clocks @ 1.025V / 70% or less GPU usage. If I can use base clocks at 0.975V or max 1.0V, I am sure the card would work a lot cooler. I am working on my own version of KoL Cooling Mod. Even with the cover off and the copper heatsinks attached to the GPU heatsink, it still gets way too hot.

    I found a thread for undervolting the 8970m from tech inferno. [TUTORIAL] Change AMD 8970M voltage It turns out after following all the steps it that the ssids are mismatched. I don't think these cards started out as 8970m's the gpu type in the atiflash tool is showing that this card is a pitcairn. Which puts it in the 7800 family. I think the ebay seller is selling rebranded ati cards. I've heard that they can do this and I bet that's why our voltages are soo high.
