SLI - will these two cards run together?

TomOrtlieb · Nov 12, 2013

Hey everyone,

I am definitely a novice at all this, so all help is welcomed!!

Based on my iBuyPower receipt...my current memory card is:

- NVIDIA GeForce GTX 670 - 2GB - EVGA FTW - Core: 1084MHz

I am looking to double up and run it sli. It was recommended to me to purchase the refurbished model found on the link below:

http://www.newegg.com/Product/Product.aspx?Item=N82E16814130982

Just to double check - 1) Is my video card and the version found on the site the same? and/or 2.) Will I be able to run them together via sli?

Thanks in advance,

Tom

I believe they are the same with the same boost clock, in any case even if slightly different they will run together in SLI.

Yes, should be fine. Just check your PSU has enough capacity on the 12v rail(s).

I agree with this, most companies that build computer cut corners on the PSU that comes with the system.

Thanks to everyone for the feedback - I will be purchasing this item. Seriously - the people on this site are amazing.

And I think (or assume) I should be good in terms of power - again...according to the receipt I ordered the:

- 750 Watt - Corsair CX750 - 80 PLUS Bronze

If you disagree that this will be enough...please let me know!

rolli59 · Nov 12, 2013

Yep that will run it.

That PSU will be fine. Im looking at the CX750M my self, looks like a nice PSU for the money.

TomOrtlieb :

Before you run sli lets double check some stuff..

Whats the model of your motherboard so we can make sure you can support x8/x8 2-way sli and also make sure you have good cooling in your case to keep good airflow inside the case while running sli..

TomOrtlieb · Nov 13, 2013

Good call - I did check around on this in regards to the motherboard and I think I am fine - but, not so sure about the cooling:

- Motherboard: Gigabyte GA-X79-UP4 -- 4x PCI-E 2.0 x16

- Cooling System: Liquid CPU Cooling System [SOCKET-2011] - Standard 120mm Fan

rolli59 · Nov 13, 2013

Yep board is fine.

TomOrtlieb :

How many fans do you have in your case but

750 Watt - Corsair CX750 - 80 PLUS Bronze - Check
Gigabyte GA-X79-UP4 -- 4x PCI-E 2.0 x16 - Check
Sli bridge - Check

Your pretty much good to go and 2 670s in sli will give you solid performance for sure at 1080p cheers

TomOrtlieb · Nov 13, 2013

Thanks again to all for the feedback:

The case I have is the NZXT Phantom 410 Gaming Case - I am not sure how many fans there are, though. Do you think it would be a good idea to add more (if possible)?

From looking at the case you should be fine but i would add a fan on the side panel as a out take if theres not one there which would give you even better cooling with sli

K cool - one of my students that is great with computers will be installing the video card for me, so I will have him check. Thanks!

Hey everyone - I received my second graphic card and amazingly with the help of YouTube I installed it properly and I am currently running the cards via sli.

Question though:

- My original card is the 670 FTW, which is more expensive and thus I am assuming includes more power...?

- The second card is a 670, but not the FTW.

They run together - but I read something about the cards defaulting to the lesser card. Is this an issue I should be concerned about? Would it be in my best interest to purchase a second FTW instead, or is it overall not a big deal?

This is another forum dealing with the issue (if it explains my question better)

Thanks.

TomOrtlieb :

1) the difference is probably not noticable between a regular 670 and a FTW

2) use EVA precision software if you want to clock the non FTW card to the same clock speed, then they will be the same.

That is what I was hoping to hear - thanks!

SLI - will these two cards run together?
