970's having performance issues using 4GB Vram - Nvidia investigating

Im sure skyrim or something with a couple of texture mods and ENBs will kill 970s
Yea maybe lol. Could be another good game to test the 970's on?
yea it slows right down..whatever it's called, so the 970 is basically no good above 3.5, no idea what their Lawyers will make of this, but to me it's not a 4.0 card
i should have got those 290X Lightnings
Wait, so the GTX970 is actually a 3.5GB card with 500MB of shared memory or something?
Soldato
Erm, sort of. Basically the card sees 3.5gb as the main VRAM, then there's 500gb that runs like utter crap when you use it.
I just read that apparently Gigabyte have released a bios that fixes it, yet no real evidence as yet.
Hmmmm....... Not sure what to make of all this.
I bought one of the Galax infinite 970's, my first Nvidia for years, maybe since a 260.
TBH, I've been running maxed ENB skyrim, witcher 2 uber +mods, and been really impressed. I haven't run any newer games though, I'll be quite let down if there is an issue.
After years of going 'value for money', which AMD is, eg the 5850's were amazing at twice the price, i finally let myself spend £300 on a GPU...... Please don't let there be a problem Nvidia!

No it is a 4gb card but it looks at the VRAM as two separate chunks 3.5gb and 0.5gb.
its 3.5 of the regular fast RAM that you find in graphics cards, then the rest is some slow ass POS RAM just so nvidia can call it a 4gb card, when you go over 3.5 it will use this slow RAM, but its so slow, that the card takes a crap and makes your games look like a piece of art from picasso
Poetic.
Soldato
No no no dude, that's not true. The ram is all the same, be it Samsung, Hynix, whatever. It's the memory controller causing the issue. So for example, you use up to 3500mb ram and you get full 256 bit bandwidth. Then you over flow that and run into the last and you only get like 64 bit bandwidth..
Ugh, it's hard to explain but yeah, the ram is all the same. They don't fit the cards with 3.5gb of good ram then 500mb of crap ram.

Check the Skyrim thread, plenty of people have it pimped to the max with 970's, myself included!
Its the IMC then?
Why does it do that? Is it hard-coded to just limit the card to promote the 980? hahaha

SLI disabled
1080p (50% scaling)
2160p (100% scaling)
Will show 4GB in actual game play though.
Soldato
That's a hell of a drop going from 1080p to 4K. Ouch 
yes they do, because those were my last cards.... so they're very important to me, it's too late now to dump these cards and switch, i may as well wait till the 390X comes out and switch then.
why? because 4GB aint enough RAM for the future, let alone 3.5
Soldato
I might install and re-run the SOM benchmark. But only if you Red fan boys promise to believe me if I post a GPU-Z screen cap with 4gb!
I don't think this is much of a glass half full crowd...
