NVIDIA GTX 595 (picture+Details)

yeah but... that still doesnt explain why the card blew...
he increased voltage from 1v to 1.2v and used stock clocks... and that blew the card? then the pwm seems to be pretty whimpy, no?

if it blows almost instantly with 1.2v and stock clocks, how safe is it to overclock the card and run it at 1.1v? how long until it pops?

hmmm curious about more info on why some 590s blew up...

Could simply be a bad component on that particular unit, no way to know if there is a overload situation unless there are others seeing the same failure.

check the article, according to w1z, yes, others are having similar issues with cards dieing from minor voltage changes :/

idk... it sucks that no review i read so far put up a sound sample of the cards under load... both cards are noisy, so the 590 being less noisy might be pointless if its still noisy... if the 590 is acceptable and the 6990 is notably louder, then that would indeed make the 590 look more attractive...

i have a feeling the 590 is less noisy but it wont really make a difference in a well ventilated case whether its a 590 or 6990... and these are for gaming rigs with nice sound systems or headphones, so...
then add to that the apparently more robust and beefier pwm of the 6990, a very open and adjustable power throttling menchanism, the easy overclock switch for 6970 clocks and higher voltages... and to me it seems the 6990 is the better option...

for people who dont overclock though, i think this is the closest ive seen nvidia and ati with their highend cards... ever... same price, almost identical performance and power consumption and temperatures overall...

With all of the issues with burnt up vrms on GTX570 I'm really not surprised. I just don't understand why Nvidia is cheaping out on the voltage regulation on expensive, power hungry, high end cards

I would say pumping the voltage on any component poses risks, your mb has enough voltage range to toast your OC marketed cpu or OC markted memory if you use enough juice, or even the pwm on the mb itself.

Just because you can doesn't mean it's going to be ok if you do juice a part.

If people are popping cards with a minimal voltage boost then who is to say how this will hold up to long term day to day use. I also think that a $700 video card should be built with enthusiasts in mind like 6990. There is no reason that there isn't some sort of hardware over current protection like we saw kick in on 4870, etc with OCCT.

i dont get why NV continues to sell anything thats gf100 based, they have gf104 based cards that have the same shader count*shader clock rating but then they are not rop starved and use less power. like the 590 uses an under clocked rop starved gf100 when they had the stock clocked full gf104 that was the same gflops and had more rops. the only market the gf100 stuff makes sense for is the benching community and they will not run an x2 they will run 4 cards given the choice so this card serves no purpose other than to prove that NV has no idea what they are doing or they think that they will have the same problem as ati when they made the high end mobile parts barts bassed even thought that was quicker and lower watt than the under clocked to end part.

if u look at the mobile parts on NV they do the same stupid crap as this and instead of using a gf104 they use a gf100 part and under clock and lock it to 384 shaders (althogh it looks like post launch some are saying that its a gf104 but the initial cards shown were square dies so gf100)

Time will tell, no use crying the sky is falling on day one, is it something to be concerned for, sure, is it a definitive wide spread product issue, too early to really say.

I mean I can't quantify how many burnt vrm's are out there from a handfull of online folks in the hundreds of thousands of units that are actually put into the market. If these issue where so widespread even on other products there wouldn't be any vendors that could afford to sell the product nor could nvidia cover excessive claims.

Is Nvidia being cheap on the vrm, I don't know, are people being too aggressive with what they expect, I don't know.

What I am fairly sure of is if there is an issue now that will potentially lead to excessive warranty claims it will be rectified in short order whether it is bios, driver, or hardware implemented.
