Thanks for the link Final8y.

While over there I couldn't help but notice the P***K that thinks just because I don't have a camera this makes me a liar. I take that to heart in a very big way... :mad:

So without further adue I've borrowed my neighbours camera phone and taken a couple of shots. Just to show I've got NOTHING to hide I've included a shot of the packing box with my RMA slip taped to the top.

Since I don't have a forum account over there anyone want to point him and anyone else thinking I'm a liar to the pictures.

Calm down squire.

Dont worry about people like that. Die hard Nvidia fanboys crying because the 590GTX has failed quite badly on many fronts.

We don't need, and don't want AMD to be the king card maker. We need competition.

Nv needs to sort out the power stage & AMD need to sort out the cooler & then they should both call it quits until the next nm.
I'm annoyed at both of them.

Agreed, competition is good for us (what most fanboys fail to realise). Nvidia need to get this sorted asap. This generation has been a huge fail from all sides in my opinion. Hope the next shows some improvements.
 
To be fair Greg, the main guy on SA(sorry thought thats what you were refering to but same for the [h] thread) is mostly just saying without proof anyone can really say anything.

I've literally seen so far no mention of a single failing 6990, then all of a sudden one reviewer makes a change to his review to update it saying his card has failed, and didn't date the update(honestly almost any half decent reviewer would post a date/time of ANY changes to a review, its VERY common to see this in reviews), then someone else on another forum apparently referencing this one guy is suggesting several 6990's have died.

Now the post was made after the 590gtx launch and after quite a lot of them have died. Is this real, while no one else has really seen any die, or did one reviewer put in some BS to make the 590gtx seem less bad, or did his really die but another guy is using that as evidence loads have died.

Unfortunately the internet is generally not a very trustworthy place in general, says more about people in general than the internet but thats life.

Thing of it is, this all of a sudden rumour, a week after 590gtx's started dying, seems a pretty big co-incidence, if one side can BS, obviously so can the other.

However, its the sheer number of 590gtx's dying in such a short time with so few sold, vs very few stories of 6990's dying in a good few weeks. Also its the WAY they die, if 1000 of any cards get sold, I'd put money on 3-4 turning up completely DOA, which is a lot more common than running something for 2hours to 2 days then it blowing.

Generally something is DOA, faulty on first use , pooped mem or something so almost instantly you get artifacts, or something dies 2 years or more later. I really find almost nothing dies inbetween. Arriving fine, working fine, and dying within days suggests the parts simply aren't up to the task AT ALL, and thats what we are seeing, and judging by the ratings of the VRM's, its pretty much confirmed they simply shouldn't be that loaded or at those temps for ANY amount of time.

Since when did a 5770 have a vapour chamber heatsink?

sapphire vapor-x did but the stock 5770 did not , striped my old one down to clean it before i sold it last year and no vapour chamber

Completely wrong, I think you didnt look correctly. The V1 5770 with the blower design (or mini 5870 shroud) had the same vapor chamber design that the current cards are using, just with a smaller heatsink.

The 6990 seems to have one of those slapped on top of each GPU, just a little bit bigger maybe.

I know what you mean... I'm just feeling like I want to jump at anyone or anything over this and that's not the way to go on the interwebs.
Deep Breath, count to 10. :)

I think the only thing that's really grating at me is that I actually liked the card while it was running. It was quiet, it did the job, and honestly I thought it looked good. Live and learn.

As for your point about temps, I have to agree. The moment after the card went my first thought was "Get it out of there fast", I went to touch the card and I'm really glad I pulled back, the heat from it was searing! I had to go get a towel and double it up before I could pull the card out of the system.
Look, I knew going into this that it would be a hot card but surely not that hot, no card could last long at the temps coming from that thing when I pulled it out of the case.

Indeed it looked like a strong card, at stock it's got roughly equal performance to the 6990 and seems to have reasonable OC potential. Significantly quieter than 6990 but pricier.
 
The latest drivers nvidia has released for the 590 have the card downclocking below 600 Mhz. The card is dropping as low as 550mhz when the OCP kicks in while gaming.

So nvidia is now having to reduce performance from stock to keep the card stable. Hopefully we will start to see review sites revisiting their reviews soon with the new drivers to show the loss not improvement in performance drivers are bringing to these cards.

This is unacceptable on nvidia's part, to now reduce the consumer's performance to keep the cards on the market.

It's time for a recall.

550 Mhz? ROFFLE.

The issue though is the temps being read are largely down to the VRM's, the cores are running cooler, the VRM's are what are running at 115C + in the pictures that have been shown. 2 more VRM chips and the load on each would be dropped significantly, if the waste on each VRM is ejected as 8W of heat on 5 chips, throw in two more chips, it will still only have 40W's total heat to dissipate, but on 7 chips instead of 5, that's 5.7W to dissipate. They are just barely working at 8W, an over 25% drop in heat output WOULD drop temps significantly. The other issue is simply the load they are running at, lots of designed for it components can run at circa 125C without dying, but if a chip is rated for 35amps and you try to draw 36amps out of it at 125C, it will be game over. Most parts are rated at specific temps, so what a chip can do at 50/100/125/150C will all be different.

Its just shoddy, really shoddy and frankly dangerous design, whats laughable is they are using cheaper components(volterra chips that handle over twice the amps per chip cost WAY more apparently) yet charging so much more, for a slower card.

Remember the rumours about AMD delays due to a lack of the new VRM chips, and people wondered why they didn't use the old ones, that would be why. My 6970 vrms are running cooler with 3 TINY heatsinks on vs a HUGE thermalright vrm cooler on my 5850, why, vastly higher capacity on the chips running at significantly lower loads producing far less heat, also supposedly a heck of a lot more efficient.

I asked on SA if anyone can tell what the VRM ratings on the 580gtx are, its substantially more robust "looking", but I have no clue of the ratings of any parts. It has 6 phase power but it appears like its split each VRM phase across 3 chips rather than one, again looking like more phases and lower load per chip, that doesn't necessarily mean better power, if each of the 3 chips is only rated at 10amps, it would be pretty much worse, if each chip could provide up to 20amps it would mean capacity is FAR higher than required and far safer.

Will be interesting to know if the 590gtx is a big change in terms of safety margin over other Nvidia cards.
