Nvidia GTX 970 3GB GDDR5? Not 4?

[Flashie]

So i was in steam big picture - and i have a MSI GTX 970 Armour, which is supposed to have 4GB GDDR5 vram, but steam says 3? Why is this?

Because it's actually 3.5GB?

[Epiceleon]

Oh no not another .5GiB

Hush child. We dont talk about that

[DarkBlade2117]

Because it's actually 3.5GB?

No it has 4GB. The last .5 is just slow and almost unusable.

[Oshino Shinobu]

What does something like GPU-Z say? I often get programs reading my vRAM as 4GB instead of 6GB, but the 2GB is still there and can be used.

Only it isn't. It's still 4GB

unusable.

[Oshino Shinobu]

unusable.

almost

 

It's still there, and can be used, it just slows things down.

ITS 3.5 BECAUSE THE 0.5 ARE UNSUABLE AND INVISIBLE FOR GAMES

almost

 

It's still there, and can be used, it just slows things down. 

So it's useless, there's no reason to use it the other 0.5Gb

Yes, but we're not saying that it's good to use. Just that it's there and that the card is still 4GB, not 3.5GB. 

[Samfisher]

Except that's not how it works.  The last 0.5GB is only slow IF the same operation (Write + Write/ Read + Read) happen at the same time for BOTH partitions.  One Read + Write and Write + Read will not manifest this issue.

YOUR CAPS LOCK SEEMS TO BE BROKEN YOU MAY WANT TO GET THAT FIXED BUD.

[Sauron]

it's a misreading

yes there is if the alternative is offloading to system ram.

Steam big picture is kinda sh!t
