Different Make GTX460 For SLI?

[viking88]

Hi I,m not up on SLI setups, I,ve never used one before, So please excuse this if it,s a simple question.
I already have one Inno3D GTX460 768mb card, but I am thinking of getting another GTX460 to try out SLI.
But I donot know if I will be able to get SLI working if I buy/use another make/Brand of GTX460 with my Inno3D GTX460 768mb card?

I saw this Asus GeForce GTX 460 Direct CU TOP 768MB GDDR5 PCI-Express Graphics Card on overclockers, will this work in SLi ok with my INNO3D 768mb GTX460 ?

Memory is the same size at 768mb, but make is different.
My Inno3D was bought from overclockers under their OCuk Value brand.

Will these 2 GTX460 768mb work ok in SLI?
Thanks for help!

You can use any two brands as long as they're both 768MB 460's.

I assume your motherboard is a X58A-UD3R?

Your sig needs tidying up. According to that you also have a 13000 watt PSU!

Yep UD3R, thanks for pointing that out, typo miss!

Good so as long as the 2 GTX460,s are both 768mb all will be happy?
Good.

Yes a Tagan 1300 Piper. Very nice PSU runs silent and has never missed a beat really.
I had 2 of them and one did go a little wonky and had to post it to Tagan under warranty BUT it got lost in the post (Stolen) me thinks! and it took me 4 months to get £130 out of Parcel Force under lost item insurance they tried everything to get out of paying,I had to pay for a solicitors letter and post that to them, but I digresss..

Good I think I will get a clearance GTX460 from overclockers and try SLI out, all reviews for 460 SLI say they are faster or as fast as a single GTX480
Thanks

Review of 768MB 460's in SLI:

Pretty nippy but with only 768MB they'll struggle at very high resolutions. Look at the Metro 2033 benchmark at 2560x1600!

The 1GB cards are better but you have what you have.

If you get a second card cheap enough it'll be a good boost as long as you don't game at more than 1920x1080 or 1920x1200.

 

[Predicament]

The cards do not *need* to have the same amount of VRAM. However, you system is only capable of using as much VRAM as the 'weakest GPU in your setup has'

Basically, your SLI is as strong as its weakest link.

Thanks again for the input..I won,t be gaming at extreme high res, tops will be 1920 x 1080
or lower sometime to my sight lower res can look better don,t know why?
Thanks again.

While what you say may work it is not the official answer given by the owner of the technology.

Direct from Nvidia:

Can I mix and match graphics cards with different sizes of memory?

No. For example, an XXXGT 512MB cannot be paired with a XXXGT 1GB in an SLI configuration.
