First Generation 9800GTX+ SLI with Newer revision?

Hello, I searched around and could not find the exact answer to my question.

I currently am using a single EVGA 9800GTX+ and would like to add a second card in SLI. However, the card has been revised and seems to be lower wattage (1 6-pin power connector as opposed to my card's 2 6-pin connectors). I was wondering if this 9800GTX from Newegg would be SLI compatible with my current one.

This is my current card

  1. 2x 9800GTX+ is a power hog setup, produce more heat and noise...
    Won't you consider sell your current card and get a single powerful card?
    I think it's better for you... :)
  2. yeah as long as they are both GTX+ it will be fine
  3. they will run like a charm ;)
    and spenthells you can run some cards at sli even if they not exactly same, just that the most powerfull of them will change its clocks etc to the same as the less powerfull ;)
  4. I was thinking the fact that they are two different sized cores it would be an issue
  5. SLI=must exactly the same type of card (9800GTX with 9800GTX)
    CF=must the same generation of card (HD5850 with HD5870/HD5830)
  6. SLi:
    The 9800GTX can work with the 9800GTX or GTX+ I believe.
    The 9800GTX+ can work with the 9800GTX or 9800GTX+ or GTS250 I believe.
    The GTS250 can work with the 9800GTX+ and the GTS250 I believe.

    CF:
    The 5850 can work with the 5850.

    Hybrid CF:
    The 5850 can work with the 5830 or 5870 - though I'm not sure whether it downclocks to the lowest card for CF performance or averages the two cards?

    The only caveat to that is the RAM size when a GTS250 is paired with a 9800GTX, they must match but a 9800GTX 512 should be able to pair up with a 1GB 9800GTX and it shouldn't matter whether one of them is a 55nm and the other is a 65nm version.

    And how much power is required then? [:mousemonkey]

    Te OP said his current 9800GTX+ is required 2x 6pin connector, that's (3x75W=225W max), so if he want to add another 9800GTX+(1x6pin) then 225+150=375W maximum.
    SLI/CF setup will produce more heat and noise, that's why i suggest the OP to sell his card and get a new powerful card...

    Correct me if i'm wrong, MM...
    You taught me a lot before... :)
  10. The 9800GTX is going to struggle to pull 140w regardless of how many power connectors it has on it, what you have to bear in mind is that not all motherboards can supply the required power via their PCIe slots so the card manufactures may sometimes hedge their bets by getting as much power to the card as possible via the PCIE's (2x75 = 150w and no power required by the PCIe slot), mix that with the various different PCB's that any one particular manufacture might use for the same card and you can end up with seeing some pretty odd looking cards that are still the same as the others.
  11. Thanks a lot, MM... :)
    So, what is the best solution for the OP thread?
    What do you think?
  12. As for the specific question the OP is asking in this thread I think it would work OK but I'd stick with two cards wearing the same amount of RAM myself, as for whether it's the best solution or anything to do with other cards that's another question possibly anther thread.
