SweClockers: Geforce GTX 590 burns @ 772MHz & 1.025V

[happy medium]

Actually, to settle this issue, this is why these cards are dangerous to OC even by a little bit: http://html.alldatasheet.com/html-pdf/312873/INFINEON/TDA21211/776/2/TDA21211.html

These are the VRMs on the PCB, its a DrMOS, rated for 35A each. There's 10 of these on the PCB for all the components. That's a max of ~350W at 1V +/- 5%. Clearly even at stock clocks, the 590 is already stressing these VRMs to the max. It's evident NV never designed the card to operate at 607mhz core clock (and using 50W more than the 6990) and were forced to do it by AMDs aggressive 6990 release.

BEFORE YOU EVEN GO THERE, LOOK UP THE 5850'S VRM'S AND SEE WHAT THEY ARE RATED AT. :thumbsdown:

yOUR CARD IS GONNA BLOW UP!!!!

 

[Grooveriding]

incoming apologetics, deflections and spin :thumbsdown:

speaking of, where's wreckage? this is kinda weird without him

The ironic part is it all being labeled as spin.

The 590 is faulty and is fragile when overclocked. Why would anyone want to recommend a card like that to someone ? It's also slower than a 6990 which sort of negates the sense of a dual-gpu halo card as being viable.

Beyond brand loyalty and having a penchant for putting hardware prone to exploding in your rig (), there is little reason to recommend it.

Volterra VT1157SF?? Can't find specs on it, but there's 3 of them for the GPU and a few others for the mem controller and gddr5.

And mine have ran OCed for a long time, it's still cool and quiet, without the exploding VRMs.

 

[wahdangun]

Well i haven't read a review where the card blow up in default settings. Do we have any link ??

ok, here there are :

^^ This , i know already of 5 dead cards from my friends that died at stock voltages stock clock running heaven and Vantage benchmark , add 2 more testing on LN2 and 2 more on H2O = 9 cards already , how many dead 590s have not been reported ? this card cannot even handle 100% full load on GPU for long periods of time , yes it will blow up in smoke even at stock voltages and stock clocks. Nvidia should make a recall on this cards me thinks :/ , so many cards 590s have died and since has not been reported it looks thats just a few cards , the truth is , its going to happen soon or later , its like a time bomb , this card its a total failure and im sad i had high expectations on this card. Ill wait for the next 28mm cards to be release , as of right now 590 or 6990 are not apealing to me at all

IMHO,whats going on here :

• » The successful rumor is easy to remember.
• » The successful rumor follows a stereotyped plot.
• » The successful rumor is a function of the momentary interests and circumstances of the group.
• » The successful rumor exploits the emotions and sentiments of the group.

Romanian reviewer has two 590s incinerate at stock.

His thoughts, the 590 has sub-par VRMs similar to the reference 570 and the problem is amplified on the 590 due to greater power requirements.

From what I can find out, those are rated up to 40A.

The GTX 460 adopts Volterra digital power supply solution, which is made up by VT1185M main controller chip, six VT1157SF subsidiary controller chips, offering switch frequency of up to 1.3MHz and up to 40A electric current for each phase.So six phase can provide totally 240A power supply capacity with conversion efficiency of up to 85%.

Seems Galaxy has used these on one of their 460 models.

Lol, from the romanian page: It is possible that Nvidia doesn't know that a quality VRM cannot be replaced by Cuda

sorry, because some member really getting my nerve (especially after he insulting W1zzard)

 

[Beer4Me]

I thought Wreckage was banned, but I could be mistaken.
GTX 590 is a good card @ stock. Don't o/c it, and don't push your luck with it. That is all. ^_^

The following is a direct quote from w1zzard in his forum:
http://www.techpowerup.com/forums/showthread.php?t=142649&page=12

so guys .. where should i stop ? after 15 - 25 mv like nvidia recommends ? or go as far as the slider lets me ?

Now 1.2v from .96v is .240v, which is 240mv, which is almost 10 times what Nvidia recommended.

Also, each 8 pin connector supplies a maximum 150watt, 2x8pin + PCIe = 375watt. At stock, GTX590 can draw up to 350watt. Increasing voltage by 20% means 350Watt * 120% = 420watt. What happens if you take more than 150watt of electricity from a 8pin? What happens if you take more than 75watt of electricity from PCIe?

I believe any 3 years old and above is capable of moving slide bars all the way to the right in some UI. If anything goes terribly wrong, they can cry out loud. Those act however, isn't what we call professional.

What W1zzard has done was childish. Putting the word EPICFAIL on his review after failing to follow instructions will do more damage to himself than anyone else. Some may like what he did, but don't we act childish from time to time? We, as a poster don't post for living. Reviewers on the otherhand, may do it for living. They are responsible for their own action and well as its consequences.

I'm not sure where the truth in this situation (GTX590 bad quality/weak components or not) is, so I'm not even going to try to guess it.

One thing is true though - that 15-25mv recommendation and recommendation for new drivers only came after this came out (apoppin in another thread claimed nvidia never told him to oc or not oc his card and to not use the supplied 267.52 drivers). I'm pretty sure the reviewers used whatever drivers nvidia sent them.

Also, each 8 pin connector supplies a maximum 150watt, 2x8pin + PCIe = 375watt. At stock, GTX590 can draw up to 350watt. Increasing voltage by 20% means 350Watt * 120% = 420watt. What happens if you take more than 150watt of electricity from a 8pin? What happens if you take more than 75watt of electricity from PCIe?

There is another recent card that goes to around 450W with the same dual 8 pin connector setup.

So that might have confused the guy.

I'll stick with my three GTX 580s.

Are we 100% sure that reference NV GTX590 PCB uses those MOSFETs ??

Do we know the model of the Voltage Controller (CHiL) and if yes do we have any PDF with specs ?? I cant distinguish the model number from the pics in the internet.

More like get more page hits?
He made a mistake and went over the top. I must admit I pumped allmost 1.2 volts into my gtx460 to get to 1ghz but not for long. I'm sure I wouldn't have done that if I paid 700$ for it.

If I blew my card, I sure would not have bragged about it, I would have felt like an a$$.

You backed down your 1ghz 1.2v overclock most likely because of the temps! Not because of fear your pcb was gonna explode!

The 590's pcb is of an inferior design....Why defend it?

ok, LAB501 has nice photos of the VRMs, Voltage Controllers and MOFSETs

Whoa. Crispy in the middle.

Whoa. Crispy in the middle.

if you read the thread he was using the drivers that came with the card when it blew because the new drivers were throttling the card to 555 and losing to much performance

 

[v8envy]

Where there is smoke, there is usualy fire. Multiple reports of factory setting cards dying in flames probably does mean the card is running right at maximum with little room left to go faster. Be sure your case and house cooling is top notch for best (and even satisfactory) results.

That said, 1.2 volts on a part meant to run at .938 is insane. Heat goes up as a square of the increase in voltage. Bumping up the voltage by 25% means the parts were run with roughly 60% more juice than they were designed for -- nobody builds in that much safety margin. Granted, the drivers should have never accepted so much overvolting, so it's not just W1zzard having a senior moment that's to blame for the pyrotechnics.

Also, it's fine that the new drivers throttle more aggressively -- I'd like to see the performance of this card with aggressively throttling drivers vs. the 6990 though. I hope this wasn't the case of NV marketing expecting reviewer cards to survive long enough for preliminary benchmarking while the end customers get much slower results with drivers tuned for RMA avoidance.

Most likely nvidia realized the mistake they made and tried to correct the hardware limitation thru drivers!

 

[Jionix]

Most likely nvidia realized the mistake they made and tried to correct the hardware limitation thru drivers!

And they are still trying to correct it --- another driver release is out to try and fix the failing card issues. Reportedly, this driver will further reduce the 590 clock under heavy load situations to around 555mhz, alternating between that and the clock you have set in the CP, whether overclocked or not.

I do not have a 590, so I am only repeating, so it could be speculation. It would be great if one of the hardware sites with a 590 would do an investigation into what is happening across these driver releases.

I find it hard to believe video cards will fry under stock settings. As to the headroom claim, if it is valid, then Nvidia will be very busy replacing goods. With SB, the assumption is the mobo will somewhat dies in 3 years, which until then the mobo no longer under warranty. With 590, it is less than a week, and warranty is at least 2 years. There are lots of QA to fire if true.
