View Full Version : 5990 is an overclocked 5970?
is this 5990 an overclocked 5970?
I saw a posting on tomshardare that this card is about to be released aith 6 gigs of ram?

I thought it was a 4GB card...

I thought it was 4GB of RAM, but yes, the 5990 appears to just be an OC'd 5970. Basically, they just upped the clock speeds to be more like the 5870 instead of the 5850. Other companies are just calling it a 5970 4GB. It will be great for eyefinity, but I think it's going to be very expensive. One article I found said $1,000.

Which would give me the best eyefinity perf at 5040x1020 ..
2 5970 or a 5990..
Considering if still have 4 gig of ram j

2 5970's. But...do you need that??????? Really? Why is anything more than 2xAA needed? If this is for bragging rights, we certainly understand, but Im just struggling finding a need even at that res....

Well you tell me..I want to be able to crank up every single detail in the game to the max and experience no lag ..on eyefinity 3 23 in lcd's..
Bragging to my friend who thinks the gtx 295 is still the best card..
I want to be able to use the max AA too..
Why do you say 2 5970..
?
Will the additional ram in the 5990 make a signifcant difference at my res...considering one 5990 has what..4 gig ram and 2 5970 the same thing...

That's not a 5990, it's a 4GB 5970 running at the full speed of 2 5870s. And if I might add, 5040x1020 is the strangest resolution I've ever seen, even if it is Eyefinity across 3x 23" monitors.
For a little more information check out the other link started about these behemoth 4GB 5970s, HERE (http://www.overclockers.com/forums/showthread.php?t=637013)
Also I just noticed, why have you made like 6 different threads in this section with the same question? It's much less confusing and much easier to answer the question in 1 thread.

So are 2 5970s not a good option?
Also how well would quadfire scale anymore? Better than the 4870x2?
It may be strange but that's what I've for.
So I guess you are saying its best to get 2 5970 4gig as opposed to 2 5970 2 gig
Does the extra memory help with increasing AA?

Not sure how scaling works on a 5 series card, still running my trusty 4890 @ sig specs. I have heard that driver support was buggy with 2x 5970s in quadfire, but this was even before Catalyst 10.2 released.. not sure if anything's improved now, but the beta 10.3 seems to be making a lot of people happy. I do think it might work better than dual 4870x2s, but I also think 1 5970 could almost beat dual 4870x2s lol.
Heh, I think 1 5970 4GB should be enough, the extra 2GB DDR5 at 4.8ghz should be able to cope with the added resolution and AA/AF. Aren't these cards optimized for AA/AF? I've been reading that the performance hit when using AA/AF is quite minimal compared to that of every card before it's time. But if 1 doesn't cut it, feel free to add a second.. it's only your wallet. ;)

Actually what I've got is a single sapphire 5970 2 gig..by adding a second is get 4 gig total..would that be enough to kick up AA to the max?
Basically what I'm asking is what if any would he the difference in running a 5990 or 2 5970s ?

If the 5990 is actually going to be released, it's just an overclocked version of the 5970. Since the 5970 uses the clock speeds of the 5850, and the SP count of 2 5870s, all they're really doing is bumping the clock speeds up to match that of a 5870 and adding 2GB more memory. Most people agree that a single 5970 should be more than enough to max out what you're playing on it...
What speed is your i7 running at? AND what is the cooling solution? If you're i7 isn't running over 4ghz.. then adding a 2nd 5970 probably won't help much as the 5970 would be bottlenecked by the CPU.

When adding cards for SLI/Xfire, the vRAM is not added togther for your total vRAM. If you have two 2GB GPUs, then you can still only have 2GB addressed at any given time, no more.

The single 5970 with AA cranked up chokes..but with AA at a lower 1 or 2 flies...
My cpu is a 3ghz i7 950..I was told that I can over clock it and get closer to 4..
Not sure how far the 950 can be overclocked..
As far as cooling.. The cpu had liquid coolind and the case has several fans..one blowing down to the expansion slots and the other from the side panel blowing right onto the video card..
With a 1200 watt power supple I dontrhave enough cpu speed?
Alienware sells systems with dual 5970 and they use the 960..

Unfortunately I've never gotten the chance to dissect an Alienware ;) and I have no idea what BIOS options they let you modify, but I would hope that they have the options to do so. If so, you should check out the Intel CPU section (http://www.overclockers.com/forums/forumdisplay.php?f=2) and look up a bit of the i7 OC'ing tips. Unfortunately most of the tips are in people's threads about how to push their i5/i7 further and not found in the stickies above. I'd try to help, but since I don't own an i7 there's only so much I pay attention to with those settings. :chair:

That 5970 will chew up as much CPU power as you can throw at it. Crank it up, and see if you notice a difference.
And some games are just buggy at certain AA settings. If it doesn't work well then adapt.
The 950 will OC to about the same level as a 920, or 960; 4-4.2GHz for 24/7 operation.
The 1200Watt PSU has nothing to do w/ your speed.
