    Thanks mr Fox.

    But how is the benchmarks scores compared to a real 980? 

     

    It depends. My core performance matches a 980, but my memory clocks are lagging behind. Basically anything that's light on memory access its basically a 980. For anything heavy it does become significantly slower than a 980, but still much faster than a 980m.

     

    Ex 3dmark11 is light on memory. GPU score is over 21k:

     

    http://www.3dmark.com/3dm11/11445450

     

    A 980 at the same core but 8GHz memory would be just under 22k. We're within 5%

     

    Now firestrike is a lot heavier on memory:

     

    http://www.3dmark.com/3dm/13442500

     

    Performance is only halfway between a 980m and 980 at the same core clocks. I can clock the core higher than that and have gotten 15500s (I can't find the result), but that's still much lower than a 980 which would be getting 17000 at the same core clocks with 8GHz memory.

  2. This is hwinfo64 info about the 3dm11 run. I had a high speed fan blowing on the card with the back of the laptop off, so that's why temps only reached 63C. I could run the laptop normally and stay under 90C in the time it takes 3dm11 to run, but that would pull too much power and cause AC to cut out. Note the 267.5W power draw.

  3. I got the 980(m?) to run the core at 1502 at 1.2V and broke 21k gpu score:

    With a little more modding I should be able to get over 1510 on the core. The last mod for that is fairly involved and makes some of the backside memory chips irreplaceable though.

     

    I tried running with the CPU overvolted, but that little extra power draw was causing the motherboard to cut AC power. I had one run with over 12k physics at 4.6ghz cpu, 2093 MHz memory, but the power was cut during a GPU test so the GPU score was only 20200.

     

    My memory clocks are killing my firestrike scores. This thing cannot consistently do 7GHz. I have an idea to try to figure out which of my memory chips are the weaker ones. Then I can selectively replace those instead of all 15 6GHz chips that are on the card. I'd be happy with 7.2ghz, but 6.9ghz makes me sad.

    Clevo has backside memory cooler for MXM 3.0b style cards. Part number: 6-33-P15SL-101

    GP104 package is not at all compatible with GM204, the MXM boards required a complete redesign and now boost like a million additional resistors and other stuff...

     

    I don't see that cooler helping much as it doesn't give a route to airflow and doesn't increase surface area much. It also interferes with my vdroop reduction mod that I did to my 4GB 980m. Instead I ordered thick thermal pads that can reach the motherboard. This will be a significant surface area increase.

     

    I might tape my thermocouple to a backside memory chip tonight and measure temps. I would be surprised to see less than 110C.

    Post your hardware ID and screen shot link here and they will add it to the database. You will need to tell them it is a GeForce GTX 980 (notebook), but I do not recommend any mention that it is a one of a kind mod. It usually takes about a week, depending on when you post. I've had a couple of times it was done the next day. The benchmarks you have already uploaded with be fixed as well, and won't be called Generic VGA any more.

     

    The thing is it is the desktop 980 hardware ID. I think what's throwing futuremark is the 8GB of memory. The Desktop 980 only ever had 4GB, with no 8GB models. I think Nvidia did that to encourage more people to buy the 980 Ti

    That's only for dx9 though, right? I don't typically play games that are dx9, especially more so since dota 2 is now fully dx11. But thanks for the tip.

     

    No its everything. If I remember right optimus x1 links usually matched or outpermed x2 links in dx9 titles, but in dx10 and dx11 x2 almost always beats optimus x1, but optimus would still be a major improvement over pure x1.

    So after this new mod with the core, i wont be able to catch you now...lol

    Well the card is no longer recognized as a 980m, so you win according to hwbot.

     

    I see the memory mod ended up working for you. What did you have to do to get it to work right? Mr.Fox can barely break 6ghz and I remember you saying you had that problem too.

     

    Also that core is amazing. What voltage?

    You can use a universal Stencil, just cover the holes you don't need with some tape OR you could go commando and do it manually, I have gone commando quite a few times when i had to get jobs done but its really tedious, your eyes go mad :06:  you have to look away every 5 minutes to adjust focus...

     

     

    Wow, that sounds terrible. I have a hard enough time with a stencil.

    good question, i was also already wondering if@khenglish also swapped out the vram chips with desktop ones?

    or maybe just overvolted the 980m vram for such insane clocks :)

     

    Sent from my Huawei Mate 8 NXT-AL10

     

    I swapped one chip because I messed it up when removing the 980m core. I figured why put a 6gha rated chip on when I have 7ghz rated chips. The others are still 6ghz.

     

    Memory voltage is raised to 1.47V. I need to devise a way to cool the backside chips if I want to go higher. Right now they have nothing. Best would probably be very thick thermal pads that reach the motherboard.

     

    Memory seems to clock the same with the 980 core as a 980m core. This card actually has the slowest memory of any 980m I have worked on. I have always gotten 7ghz stable if the temps can be kept down, but this one can only do 6.9ghz stable with an external fan blowing in the card. I don't really want to swap 15 memory chips...

     

    The GM204 bga stencil is easy to find. The bga matches the older GK104 (680m, 680, 670, 660ti, and more), so you can just get a GK104 stencil.

    Me personally would just order the right one. Less chance for a mistake.

     

    Although I'm still waiting on the new cards though. To see if they can be put in here or would i need to buy an upgraded chassis.

     

    The 980m pcb can probably take a gddr5 gp104 core.

     

    The bios modding required though would be... extensive.

  9. I wouldn't bother switching a desktop 980 core onto a 980 notebook. Right now my core isn't clocking so hot. Not sure if its just not a very good core, or if the 980m voltage filtering is having a hard time with the current draw increase.

     

    The card is going to receive voltage filtering improvements to try to improve clocks. Memory will be targetted first as right now I can even bench 7ghz long enough to complete tests.

    Holy shit wow!! Congrats! You are a freaking legend, and you just broke my wallet.

    Do you think the solder will melt using a hot air station. ?

     

    Do you plan on trying something similar? I killed over a half dozen cores before I did a successful swap, so if you do you want to start on hardware that is much cheaper.

    That's phenomenal, bro. Maybe now you need a second 330W AC adapter and a AC-100 Y adapter.

     

    I think I can improve efficiency to make a single 330W PSU adequate.

    I havn't been on BGA Mods for over a year probably, I knew the old owner from years back and when he sold the business I lost interest (just coincidence really). I have no idea what shit those guy are talking over there now, when I was a mod there I banned anyone that was rude or derogatory towards anyone interested in this field, I had zero tolerance because there used to be another website (cvxgameconsolerepair I think it was) where they flamed the new members constantly, a pointless exercise to inflate the ego's of the senior members. Not very different to most forums in that respect, but this place seems cool so I wanna hang around for a while and offer any help I can.

     

    If you link me in PM to your BGA Mods post I will log in for the first time in years and give you my support, everything I learnt in this field I either learnt from others or was done by my own practical tests, by the end I pretty much knew everything there was to know and was sharing that information with others.

     

    I might grab some of my guides from over there and see if I can get them posted over here.

     

    Again sorry if I offended you. Its great to have you here.

     

    Not sure what core swap I will try next, but there's bound to be one.

    Chill man, I'm not here to judge, and your right, you work with what you have to hand and hope for the best. I started out as a hobbyist like most people in that particular field and only bought equipment when the profits made it viable, it looks like you have done a really great job with the tools available to you. Glad you read up on some stuff.

     

    Any rework station is better than none; certainly for motherboard work to isolate the heat and not hit reflow temps on every BGA on the board especially the tiny RAM chips, all the same, if I'm not wanted here I can go straight through the same door I came in from. Why you so Salty?

     

    Again though looks like you did a good job with the tools to hand, pads looked intact and flush to the board, Reball looked fine also, it has a decent/good chance of success.

     

    It was a joke. I did not mean to be salty. My first few posts on BGA Mods got some skepticism.

     

    I was a bit worried that you immediately seeing the toaster would make you disinterested. The first few replies I got on BGA mods told me to stop trying this stuff.
