SLI Same card diffrent...

[TheIcePhoenix]

I need to know if I can SLI 2 980ti's
same series but one is EVGA SC let me be clear that the EVGA card is Overclocked by manufacture and the other is a Stock.
only reason I am going for this is I already own the evga card but cant find another matching card for a reasonable price anywhere and doesn't take 1 to 2 months to ship as well.
Feel free to recommend a better match-up if you can but please leave it at or below $659. please if someone can find the matching card for equal to the price i stated above link it to me. but only if it is in stock and ships in the next week not next 1 to 2 months! Thanks for your help!

Here is the card I own
http://www.amazon.com/EVGA-GeForce-Superclocked-Graphics-06G-P4-4992-KR/dp/B00YDAYOJG/ref=sr_1_2?s=electronics&ie=UTF8&qid=1439301530&sr=1-2&keywords=GeForce+GTX+980+Ti

And here isd the card i am thinking of getting to pair it with.

I Recommend this card:
http://www.evga.com/Products/Product.aspx?pn=06G-P4-4991-KR
it is currently unavailable from evga but if you select auto-notify evga will email you the second you can buy it from their site.

it is available here for 648.99:

you have the reference cooler design on both cards you picked. the reference design is louder and less efficient than an aftermarket design. the graphics card link i gave you has the information about the cooling benefits of evga's acx 2.0+ design.

Yes

Are you ABSOLUTELY sure that I can pair a factory Overclocked card with a STOCK card that is not factory Overclocked?

$650 is not small amount to not be positive on. that's why I am double asking you.

I already own the EVGA card in the first link. Thats why i am looking for a matching card. the onyl problem is i cant find the same card anymore at a reason price. the one i have is a factory overclocked card and i need to be sure i can pair it with a non factory OC card

Yes. As stated, both cards are reference designs, reference cooled. EVGA just added a mild overclock to the SC version. You can use a program like EVGA Precision X or MSI Afterburner to sync the clocks. It is likely that the drivers will handle syncing the GPU boost clocks for you. Verify you have at least an 800-850W quality PSU and some good intake/exhaust fans in your case for those reference cards.

here is the lowest price you can buy your same card for
http://www.ncixus.com/products/?usaffiliateid=1000031504&sku=109570&vpn=06G-P4-4992-KR&manufacture=eVGA

the reason the price is higher is because it is unavailable through evga directly.

clock doesnt matter. please read the sli requirement link i sent you.

it will clock to the slower card.

you can also buy the superclocked acx 2.0+ version for the same price which i would highly recommend. same clock, better cooler.

I am sure im good on those fronts
1500 watt PSU and Tt core 9 case with 13 120 mm fans hopefully i can find myself an affordable Waterblock for them in the future too bad my main spot frozen CPU is gone.

Like nerdrage is mentioning, you would probably be able to stave off the purchase of water cooling by buying a custom card (like the EVGA mentioned) and making it the bottom card in the SLI configuration. The custom heatsink will help to draw heat away from the reference card. Just be mindful of overclocks and check the ASIC quality of both cards to see what kind over clocks you can coordinate. Or just leave that both at stock clocks, the GPU boost on 980 Ti's are pretty great.

I would not get another reference cooler... Get a nice aftermarket cooler for your next card, the EVGA AXC 2.0+ / MIS Gaming / Asus Strix / Gigabyte G1 / Zotac AMP! are all good choices, get the cheapest one of those you can. You will want to put your reference model card in the bottom slot and the after market cooled card in the top slot, this will keep the overall temperature of the cards down.

Currently the AMP! is the cheapest with the AXC 2.0+ right behind it:

I'd personally pick the EVGA AXC 2.0+ out of these two options.

That is exactly the opposite of what happens, you want the aftermarket on the top because it is better able to handle the hot air coming off the reference model card below it while the reference cooler ( blower ) pushes most of its hot air out of the back of the case (should see reference card with temps around 75-80c and after market card around 70-75c in this configuration). Putting them the way you suggests turns the reference card into an oven while the aftermarket card stays nice and cool, something like 65c on aftermarket while the reference hits 85c+.

Ah yes sorry, that is what I meant to say. Screwed up that post.

I don't think that will matter too much since my cards stand vertical and not sideways the core x9 case lays the mobo down flat rather then standing up. plus if i get a second reference card i can get 2 matching water-blocks but if i get 1 reference and one non reference card then my blocks likely wont match
