    I just read about the GTX 780M and cannot find any information as far as the compatibility with the M17x R2. I know that they're the same architecture, but shouldn't it be more complicated than that, or no?

    The only thing I noticed is that UpgradeYourLaptop on eBay is selling the GTX 780M and it states it can be used for the M17x R2. However, I am wary as one auction incorrectly has the GTX 680M listed in the specs, and for both, the drivers lead to 680M. I checked the inf file in the drivers and there is no indication of GTX 780M at the bottom...

    Any thoughts on this?

    It should work . . . but you'll have to figure out a way to cool the memory chips on the back of the card. SLI will be more tricky though - look for the thread where some users on hear got GTX 580m SLI working in an R2.

    Wouldn't you have to cool the memory chips on the back of a GTX 680M too then? Or is that different somehow (thinking they seem similar)?

    I had talked to The Wiz before about GTX 680M SLI before but he moreorless stated that it wasn't going to happen. I'm guessing that means GTX 780M SLI is out...

    I talked to UpgradeYourLaptop and I guess the links have been updated now for the new drivers, so I guess it will work, but not willing to try at $800!

    Eager to try this out too. I suppose the fan on my old 5870 setup and the 240W PSU are sufficient right? Just one card is enough since Xfire/SLI seem to be quite troublesome. Also there's a recommendation on the eBay page regarding HWINFO, does it mean I have to keep an eye on that fan speed everytime the machine's up and running? Can it be automated?. It's my very first upgrade and skipping 680M altogether for the 780M. Need to do careful research before shelling out $900. Thanks all :)

    It might be worth contacting upgradeyourlaptop and see what sort of things they've found in their testing (and whether they verify that it will indeed work and will refund you if it doesn't). I know some folks have had trouble with them as far as support goes...I've had great luck with their cards (6970's), but didn't need to contact them for support.

    It would be intersting to see what they say, regarding HWINFO I wonder if that means that you have to use it to manually control the fans...that would be my guess, but can't say for sure.

    Good luck, will be interested to see how it goes.

    I don't think anyone has tried it yet. Haven't seen anything but questions about it.

    If a 680M works is it safe to assume the 780M also works in the R2? What might be the biggest issues? Heat, cooling and power consumption?

    Biggest thing will be cooling (memory chips on the back) and SLI. I agree that there's no reason why it wouldn't work though.

    i would love to install one of them new monsters.
    I do not think there will be any problems with installation, only those bloody memory chips on the back.... i also do not know if 24% performance gain is worth almost 2x extra money comparing to 7970m price point.
    I would wait with purchase, firstly, i would ask eurocom about R2 compatibility, as it was done in 7970m case.

    another problem is i play only diablo 3 and starcraft 2, and in both cases i have 100FPS on FULL MAX HIPER settings, why would i spend more ? to get 120 fps ?........my eye will not see any difference :(

    ANyways, if Fellas from eurocom would send me one card, i would carefully try to do a closer look, test, test, test.....and make a guide on How To :)

    And i will be doing this in 1-2 weeks, wish me luck :)

    Gddr5 does not need active cooling just not being smothered is fine.

    Best of luck on the installation. I too am up for an upgrade as my 5870Ms on my R2 were just recently sold and need to put in a replacement. Hope it's as easy as the GTX 680M upgrade. :thumbsup:

    680m = GK104
    780 = GK110
    780m =KG 104/106
    It's an 680m(Technical Upgrade) on steroids.

    The memory chips on the back offcourse need cooling but this was also the case with the 680m 4gb cards.
    Just throw a thermal pad on them and you ar good to go.

    I can't think of a reason why the 780m wouldn't work, It's just a driver recognition issue which should be easily to solve.
    I asume it will work the same way we mod the drivers for the R2 for the 680m, It's just a matter of knowing the correct HWID code.

    What does concern me is the heat from the Die itself.
    The thermal capacity of the R2 GPU/Heatsink is almost not enough to keep the 680m a cool and now the Die of the 780m should generate allot more heat.

    Copper shim mods anyone :cool:

    Anywhere from 28 tot 93 degrees :)
    Any card will remain acceptably cool offcourse but, all gpu's get overclocked so thats more the temp. range i was refering too.

    Uh, seems like a bad paste job to me, or a bad thermal paste. Or something else.... R2 heatsink is way more than enough to keep 100Watt card cool, but the paste job is important as well as good contact across all elements, witch can be tricky....

    7970m is a 100W card, 780m is 100W card as well

    i keep my 7970m at 75-83'C max (100% load) and 32-35'C Idle, so i expect same temps +/-5'C on 780m....

    You are kidding me right... You are telling ME i did a bad pasting job??
    I have the highest benchmarks for the R2.
    I have the highest stable clocks on the cpu and gpu...

    I wrote a walkthrough on the difference between thermal pastes and thermal pads.. I even re-alligned my heatsink..

    What can you tell me that you knwo for fact?
    So you are telling me, that an M17xR2, that never had a heatsink designed to handle more then 80watt... 5870m.... a m18x that has special 100w rated heatsink for the 580m series.... That my card runs hot??

    Offcourse it's a 100w card. The design isn't allowed to go passed 100watts.
    You calculate temps based on asumption and tell me i did a bad paste...

    What kind of drugs are you on my friend....i would like to test this drug :)

    sort of on topic:
    Did you overclock your 680m? If not,....83 degrees is hot for stock clocks, i reach those temps when i clock my core to 950 and ramp up the memory... You might wanna repaste that baby.

    EDIT:
    You have a 7970m and not a 680m
    Never mind

    Flingin,
    Any updates on the 780m in the r2?
    I am very keen to see the results of this setup.

    The memory chips on the back need a bit of room to breathe, not cooling.
