Tech Report: Nvidia, Asus put the clamps on GTX 590 voltage

[Seero]

What I said is true what he said is false.

Lol, so what happens to derailing now?

What I said is true what he said is false.

Overvolting lockdown kills any room for performance improvement from the GTX 590(you may get 50-100 mhz) while the HD 6990 is left to go high as it can (1000+ on core).

By him repeatedly stating that AMD doesn't warrant graphics cards he is spreading fud because AMD never has and probably never will warranty graphics cards, its the AIBs that provide warranty.

I dont know about on air..there was a poster here hitting 110c with his 6990 on air.

This baloney about AMD not warrantying cards is fud. Why do you think AMD lists their graphics lineup on the AMD web site and have a warranty policy outlined? As well as specifications and requirements.
Its related to expectations of the product. The product they have designed. AMD putting a yellow sticker and posting extended warnings beneath the 6990 is reality.
It tells me proceed with caution , at the very least.

More like :
"Do not use the 450W setting unless you are familiar with overclocking and are using high-quality system components to ensure maximum system stability. If you encounter system instability or other unexpected system performance while using the 450W setting, return the graphics card to the factory-supported 375W setting, as your system may not be properly equipped to handle the increased demands of the 450W setting."

Right from their page man you are trying way too hard here. Also let me know when AMD released their AMD branded HD 6990.

110c is much too hot for a GPU and will kill it quickly.

 

[badb0y]

110c is much too hot for a GPU and will kill it quickly.

It was a joke lol, but yea 110C is too high for the VRMs. I would suggest aftermarket cooling before overclocking but that's just a personal preference to maximize returns.

What is the policy of Intel/Nvidia on OC'ing? For GPU's..It is AIB's who take care of warranties..

By your statement you should not have oc'ed your CPU/GPU.. hmm.

Life of any semi conductor device reduces just by supplying stock voltage to it... by OC'ing you just make it die a little bit faster.

110c is much too hot for a GPU and will kill it quickly.

The 590 runs at even higher temps for some of the other components right while just running games? He was also running 2 of them in crossfire while running a GPGPU application. Do that with a 590 and it will likely throttle or explode.

Besides GPU temps can be fixed with better cooling. The VRMs on the 590 on the other hand are only good for typical workloads at stock settings. Which isn't a bad thing, but why settle for just good enough when prices are the same?

I'm sure you 3.9ghz core i7 doesn't use the stock intel cooler does it?

I believe someone on this forum called AMD a status quo company only doing the bare minimum. Well I hope he/she enjoying their humble pie.

 

[f1sherman]

Infineon DrMOS used on 590 is 150C rated.
That I do know.

Can someone explain to me what other characteristics makes 6990 circuitry more robust apart from having 1 phase less per gpu and 30C less rated DrMOS.

That is one big advantage of the 6990 I think. You can add aftermarket air coolers or a water block and go nuts if you want. The card can handle it.

I am curious to see if Nvidia's partners make some nicer non-reference design parts, though. I have to believe that with a more robust power delivery system and higher clocks a non-reference card will fly.

But, as I've said a few times (and no one has really challenged it) is that I can't think of a good reason to buy a GTX590 over a 6990.

 

[Seero]

Define explode.

I don't know what your getting at, elaborate.

... Make your own thread, don't derail other people's threads.

That, is what I am getting at.

Describing a burned out chip as explode sound like FUD, and you are spreading it.

Overvolting lockdown kills any room for performance improvement from the GTX 590(you may get 50-100 mhz) while the HD 6990 is left to go high as it can (1000+ on core).

Again, another FUD. The default core clock of 590 is 607Mhz, not 50-100Mhz. Maybe what you mean it 50-100Mhz more, that is 657-707Mhz.

On the other hand, 6990 core clock is 830Mhz, bios2 brings it up to 880Mhz, that is 50Mhz, not 1000+ Mhz.

After switching to bios2, you can push it more, but do note that the system starts to throttle.

By him repeatedly stating that AMD doesn't warrant graphics cards he is spreading fud because AMD never has and probably never will warranty graphics cards, its the AIBs that provide warranty.

So he is stating facts right? but then you said

What I said is true what he said is false.

So facts are false, and FUDs are truth... so confusing...

Yes, AMD is telling you not to OC if you don't know what you are doing, not even 50Mhz. notty22 is trying to tell you that it isn't safe, and AMD is not responsible for any damage done.

You can get 50Mhz off 590 easily without adjusting voltage, but you knew that already. Going beyond 880Mhz on 6990 will also void the warranty from AIB. That is what you probably don't know.

One more thing, 590 at 607Mhz is as fast as 6990 at 830Mhz.

 

[notty22]

AFAIK, it's about 11% as someone here who owns a GTX 590 was able to reach 674MHz, it isn't bad but not spectacular either compared to the HD 6990 which can reach over 960+MHz with ease.



You are totally right, AMD doesn't give you warranty of damage done by overclocking for like forever, but suddenly now it matters as its rival dual GPU solution can't overclock very well and the fact is that neither nVidia or Asus gives you any warranty if you kill your GTX 590 by overclocking, not even Intel does that. So I think that the warranty issue is bollocks as overclocking is a risk that everybody takes when they decide to overclock a videocard, processor or even RAM...

The gpu's may hit 960mhz, it does not mean that the 6990 does not also throttle. The 6990 here at Anands throttled on the 830mhz bios during Metro2033.

By capping the power consumption of a card at a set value and throttling the card back if it exceeds it, AMD can increase GPU clocks without having to base their final clocks around the power consumption of outliers like FurMark. The hardest part of course is finding balance – set your clocks too high for a specific wattage and everything throttles which is counterproductive and leads to inconsistent performance, but if clocks are too low you’re losing out on potential performance.

Can someone explain to what other characteristics makes 6990 circuitry more robust apart from having 1 phase less per gpu and 30C less rated DrMoss.

A quick google search discovered the 590 has 5 phases per GPU rated at 35A each, the 6990 has 6 phases per GPU rated at 80A each.

Simple really, up powertune to +20% and you get no throttling or failing cards and still under warranty. If you get an XFX, Powercolor or sapphire card, just flick it to 880mhz and you wont get any throttling, failures or voided warranties.

Another thing, AMDs overcurrent protection is hardware based, so drivers won't kill your card. That throttling you have above there is so that the card doesn't pull more power than it is allowed and not damage your PSU, not to prevent damage in the case of a certain green card.

http://www.hardwarecanucks.com/foru...s/41404-amd-radeon-hd-6990-4gb-review-22.html
Also, 972mhz. I don't see throttling here.

The fact that it can pull as much power as 580 SLI and still not fail is quite impressive.

 

[Keysplayr]

I thought there were 10 regulators per GPU?

 

[f1sherman]

GTX 590 = 10 + 4

"Powering the twin GPUs is a 10-phase advanced digital power controller with over-voltaging capability, while two dual-phase controllers provide power for the board's GDDR5 memories."

6990 = (4+2) x 2

@Keysplayr Aintu NVidia guy. Do I really have to google this

 

[SlowSpyder]

Define explode.

I won't give you an definition, but here is an example. Sure, it's not Tsar Bomba, but in slow motion it looks like the part 'exploded' to me.

I'll take that as fact, when I see o/c reviews. I would hope, the 880mhz bios settings with +20% powertune (max) functions. But IMO , your going to get throttling at some o/c level, depending on the game/app and the resulting power pull.

 

[f1sherman]

BIOS(es), OCP, PowerTune being more robust on AMD - that I do agree with

 

[badb0y]

Define explode.



That, is what I am getting at.

Argue more semanics please, you say burned out I say explode at the end of the day it ain't working.

Again, another FUD. The default core clock of 590 is 607Mhz, not 50-100Mhz. Maybe what you mean it 50-100Mhz more, that is 657-707Mhz.
I thought that would be obvious....
On the other hand, 6990 core clock is 830Mhz, bios2 brings it up to 880Mhz, that is 50Mhz, not 1000+ Mhz.

After switching to bios2, you can push it more, but do note that the system starts to throttle.
Really? It throttles that much? Post benches please.

So he is stating facts right? but then you said

No, I am saying AMD, nVidia, Intel don't warranty their chips of you OC them out of factory settings but here's the kicker, AIBs do warranty their cards. I don't know why notty needs to bring AMD into the equation because the relationship is strictly between you and AIB when you RMA.


Yes, AMD is telling you not to OC if you don't know what you are doing, not even 50Mhz. notty22 is trying to tell you that it isn't safe, and AMD is not responsible for any damage done.
Hey, we all agree on something here!
You can get 50Mhz off 590 easily without adjusting voltage, but you knew that already. Going beyond 880Mhz on 6990 will also void the warranty from AIB. That is what you probably don't know.
Wrong, XFX and EVGa both support overvolting/overclocking - don't take my word for it, call them like I did.
One more thing, 590 at 607Mhz is as fast as 6990 at 830Mhz.
But not as fast as 880 or 950 or 1000, the point is with a GTX 590 your locked down.

If you want to continue PM me, we are going way off topic here.

right about 590. but i think amd does 4 @ 80amp per gpu on antilles

Are you guys sure there aren't 10 per GPU?

Check this video at exactly 1:07

[f1sherman]

my sentiments exactly Mr.Tempered81. Another 6990 myth is about to be busted ??

http://www.gamemunition.com/news/nvi...s-off-gtx-590/ <---- told ya 10 + 4 (total)

 

[Skurge]

Probably, I must have read the GPU and memory phases together, my mistake. Still, at 80A per GPU thats more than double for what is on the 590 for each phase.
