Solved GTX 260 SLI Question

[Andreas W]

Hello

Going to buy a new graphic card to replace my current 260 I have, but instead of getting rid of this card I want to give it to my brother that have exactly the same model and card. But I am not sure if his PSU is enough, he got a Corsair HX 650 would it be possible for him to run these cards in SLI? or just have both installed and use 1 for phys x?

hi,

a 650W PSU should be enough for SLI 2 GTX 260... Post the specs of your brother's pc please..

yes, you can use a GTX 260 as the main GPU and the other GTX 260 as a PPU, but you would not gain the same performance boost which the SLI bridge gives.

He have a Asus P7P55D motherboard a I7 860 Lynnfield with HT turned off and no O.C & psu is a Corsair HX 650, he have 1 hdd, no dvd drive, 5 fans & 1 pci-e wlan card

yes, with this pc 650W should be ok for SLI 2 GTX 260... try it
(turning HT on will boost performance too)

I have tried HT off and on and in gaming I don't notice any performance boost, and I don't do any kind of benchmarking so left it off to reduce heat . and I will try it. But if it don't work how is the computer going to react so I know what to look for etc, this would be the first time ever running SLI

I never used SLI because my motherboard has got only 1 PCI-express slot

If you SLI 2 GTX 260, you will receive a 35-60% performance increase in games, reaching the GTX 295's performance (i searched in internet and I founded that a lot of people say this). This would be a nice boost, and maybe you will be able to set some settings in games at a higher level... For example, SLI helps a lot with the Antialiasing!

why not try it?

Will do, just have to buy a SLI bridge, does it matter what brand it is, because I only seem to find gigabyte sli bridge while my cards are from asus

I searched on internet and i find that your motherboard supports only CrossfireX and not SLI... I'm sorry...
I see also that yor motherboard has got 2 PCI-express slots, but one of them run at x4 speed instead of the x16 standard speed. This complicate the things...

My suggestion is to use a GTX 260 "only" as a dedicated Physx card... It will not boost performance as a SLI configuration, but it might help a little...

No. It makes no difference what brand it is. It's a universal connection.

However as Dorado mentioned, the P7P55D does not support SLI.

And the x4 speed of a 2nd card would hurt performance. His suggestion of a GTX 260 "only" as a dedicated Physx card is the best option for your brother.

 

[Andreas W]

Oh, wow. That kinda sucks I tought all mother boards supported SLI and Crossfire, or maybe its because its so old?

Might just as well try to sell it for a cheap buck the card is still working fine. And now I am actually happy that I am kinda lazy and dident order that SLI bridge I was looking at.

Thanks for all the help I got about this
