Installing a new Graphics Card

I was under the impression that as long as its the same model of NVidia card, you could SLI two cards with different amounts of VRAM, but it will then only make use of the lesser amount of VRAM.

Yes but it is not recommended and you need to use Coolbits to "force both of the cards to use the lower of the two memory sizes and operate them together in SLI mode"

Coolbits was meant for older GPUs, you can SLI modern GPU's that have different vram,
the driver will automatically use the lesser amount of VRAM as Rakk said.

Not on a modern card as the driver will NOT allow it . Nvidia states this , its only radeons drivers that will allow it to use the lesser amount of ram on modern GPUs

Coolbits will only work for older Pre 2009 drivers

Unless you know some way of using a pre-2009 driver for a 2012 line of nvidia GPUs ?

People are not disagreeing with you just for the sake of it, during my lunchbreak (which is now about over), I've found numerous (recent) threads showing that it can seemingly be done (though obviously not fully supported by NVidia).
So it really depends on which forums/threads you read as to what you find.

From my experience.

Will a modern nvid gpu SLI with two different amounts of VRAM? Yup.

Will the driver allow it, latest release that is? Yup.

What amount of VRAM will be availiable? The smaller amount of the two cards.

Is it supported by Nvidia? Nope.

Ill say it again post 2009 Nvidia drivers will not allow it not even with coolbits - nvidia enforced this in the drivers , but hey go ahead get two 680s one with 2gb & one with 4gb & good luck getting them to work when NVIDIA has purposely blocked it in the driver even when trying to use coolbits , being this little tag team you two have seem to know better than nvidia do.

And the result is in. SLI no worky worky.

2GB 680 and 4GB 680, Choose Physx card, no SLI options on standard 30whatever driver.

Can probably be hacked / has a workaround but as it stands Baron called it correctly.

Proven with science.

Thank you gorman for actually trying it out & stopping posters from purposely trying to make me look bad & make it look like i dont know what im talking about.

I cant thank you enough :eek: + rep

Was just curious is all. No one here called it either, not a configuration we come across, erm, ever really.

Hehe, learn't something new today :)

I was never trying to make you look bad, I was questioning because I believed otherwise (wrongly as it turns out) and I've read quite a few threads (some quite recent, as in earlier this year) where they claim it's doable - it is after all human nature to question.

Rakk i never quoted you saying YOU were saying anything to me at all - i quoted vanthus , there was nothing wrong with your question at all & i replied with the next post with just some sites (nvidia included) for you to read & you did not say it was definitely possible , but could be done which is a fair statement

But vanthus as usual jumps right in & completely say oh yes its definitely possible & baron is wrong ( although he doesn't ever actually state this , he instead just tries to make me look wrong) - he does it on purpose in nearly all of my posts

But anyway my beef is with him & not you at all you did not make me look bad or even try - he did & he always tries to admittedly the "tag team " thing was wrong of me to say & i apologize for this statement as it was not fair

But anyway gorman has actually installed two different ram size cards & sli & it did not work ,.

So would it be fair to say it can in fact be done - but the chances of success are 50/50 at best & even if it does work you could face stuttering , screen tear (even with v-synch enabled) & a whole other raft of potential issues ? - after all there must be legit reasons why nvidia say not to do it

I was replying to a post from rubensolo,my answer was In no way aimed at you,
http://www.pcspecialist.co.uk/forum...-Graphics-Card&p=143941&viewfull=1#post143941
I answered that "Coolbits was meant for older GPUs," which you appeared to agree with,I also said "you can SLI modern GPU's that have different vram," & according to what I've read on these forums & other tech forums people have done this,so thats what I believed.My post was not in response to your post.Gorman ran a test on two particular graphics cards which apparently proved it couldn't be done,I still think it could possibly work with other configurations &/or cards,however if I'm wrong I'm wrong & I will be the first to hold my hands up.I dont see why it should upset you because someone has a different opinion,this Is nothing unusual,there Is really no call to get bellicose about It,I have no interest In making anyone look bad & as far as I can recollect I have only disagreed with you twice before,hardly "nearly all of your posts" & your response was quite unnecessarily aggressive on those occasions as well.
Saccharine as it may come across,my only interest on the forums is trying to help people if I can,and to get help myself from people who know better than I do.

I don't understand what bellicose means m8 , i don't need big fancy words to make a point & as far as aggressive goes bullies only understand aggression ,

Fact remains , i don't seem to fall out with anyone but you & i wasn't wrong after all , & its not the first time either , i don't give advice unless i thoroughly research it first , but anyway just keep just keep disagreeing with everything i say if it makes s you happy - you'll just keep getting the same responses m8

I have tried to end this stupidity with you a while back , but you don't seem to want to so fine , im a big boy , i can handle it :eek:

I am sure that neither side has intentionally meant to cause offence, can we leave it there please?
