Hi, as I understand this particular board has more VRM's than the refference GTX 570's so I assume that modding the bios for the card to run at 1.15vc should be safe correct?
 
BTW I have checked around, googled, and everything else and can find very little info in this card in terms of max safe voltage etc.

    It's an ASUS... >_> 1.05 might be safe but not to sure on 1.15

    This is not your typical gtx 570 though, I think it has either the same number of VRM's as a GTX 580 or maybe even more? Thats why I was thinking that it should be safe for 1.15vc but I wasnt completely sure.

    Just want to share my dead 570 experience. I bought the Gigabyte GTX 570 OC Windforce 3x (GV-N570OC-13I) last friday. It comes factory overclocked @ 780 core/1560 shader/1900 memory. Default voltage is 1.00V. With these settings it worked fine under Furmak, Kombuster, Unigine and Far Cray 2 ( i never disabled OCP).

    Then overclocked it to 850/1700/2250 keeping the voltage at default 1.00V and in less than 3 minutes during furmark run my card died (temps were 65-67 degrees. I didnt check the PCB since I will RMA it today. But im sure its a burnt VRM.

    From the looks of it I am the only one whose card died at factory default voltage of 1.00 (with OCP on) despite having the Windforce 3x custom cooler. So I did quite alot of research and found out that (between custom 570s);

    - Gigabyte 570 OC Windorce 3x and MSI 570 TwinFrozr II both use the reference PCB design with 6 phase VRM (4 for GPU and 2 for memory). They simply put a custom cooler on top. MSI cards have similar incidents reported
    http://forums.hardwarezone.com.sg/sh....php?t=3072063

    - Gainward 570 Phantom, Gainward 570 GS Goes Like Hell, Palit 570 Sonic Platinum all have 8 phase VRMs (6 GPU and 2 memory). Same amount with the GTX 580. All these cards have identical PCB since they belong to the same graphics card manufacturer group
    http://images.bit-tech.net/content_i...phantom-1b.jpg

    - Asus GTX570 DirectCU II also has 8 phase VRMs (6 GPU and 2 memory)
    http://www.techpowerup.com/reviews/A...ages/front.jpg

    And so far I havent seen similar incidents with any of these cards on the net. Which really brings me to the conclusion that this problem is only for the reference design 570 PCB with insufficient VRM phases. Based on the custom cooling abilites of my card, I am positive that temps have got nothing to do with this problem.

    FYI, the GTX 590 has 10 GPU VRMs (5 per GPU) and already someone has blown one. Clearly 6 phase looks like the best solution since GTX 580 seems to working fine for everyone.

    If I can get the RMA replacement, I will try to get a Gainward 570 Phantom instead and I will keep you posted on how it goes.

    Thanks guys, I feel a bit better now that I know it has the same number of VRM's as a gtx 580.   Im using 1.138vc right now for 950mhz core and so far so good after hours of heavy gaming. The back of the card does get pretty hot to the touch though where the vrm's are located, I guess I just need to make sure I keep the fan speed up a bit to keep them cool.

    I'm sure it's safe as long as you cool it well, ramp up the fan to blow more air on the VRM's as you said. These guys in that link either have bad cards or junky PSU's or something else, because I've OCed non-ref GTX 285's that sucked more power on crappier phases for months. The DirectCU has a row of those Eagle phases that were used on MSI's Lightning card for extreme OCing. The card is capable of more than 1.15, this is no Trio R30 crap. Also, the core is cooled very well on that card.

    I want to add that the quality of the phases is what you should look at. Companies are taking away customers` money with more phases = better theory. Like Gigabyte's 24 Phase Power crap, which gets beaten by DFI's 8 way Digital phases. They take 8 phases and split them into 16 then to 24.

    I'd be worried about it's memory because they aren't cooled on the DirectCU. Put some copper VGA sinks on them and you're good.

    Thanks, that was really helpful info. It is a sweet card, im at 950core right now with 1.138vc and with the fan speed at 50% im only seeing in game load temps of 55c. I will certainly be adding some sinks for the ram but from what I understand the ram chips do not get that hot anyway and the air from the cooler blowing directly onto them is usually enough. But to be safe I will sinks to it as I stated.

    Yup, that's a nice card if you don't mind the 3-slot cooler. The RAM may not get hot but it'll be affected by the hot air that comes from the GPU or the VRM. Since the card blows air onto itself, the air coming from the fins isn't going to be cool air. Enzotech or Thermaltake's copper BGA sinks are recommended, TT's are heavy and good looking. I'd suggest the Enzotechs myself, I put them on wherever I can.

    I know everyone here and in those other linked posts have good intentions, but the number of VRM phases means nothing without further specifications.

    With more phases, people assume that they will be capable of providing more wattage to the core and that each phase will be carrying less wattage and will therefore be less likely to burn out. But can anyone confirm the designed wattage limits of the GTX 570, GTX 580, and non-reference GTX 570 cards?

    My point is that having two more phases in the non-reference GTX 570 design would be no better if the VRM for each phase was only rated for 3/4 of the wattage of the reference GTX 570.

    I'm only playing devil's advocate here and not necessarily implying that the non-reference GTX GTXs are no better that the reference GTX 570s. All I am saying is that you guys need to start asking the right questions and start doing the right research to find the true answer instead of just assuming that more phases = better.

    Those are good points worth considering, I was under the impression though that the phases in this specific gtx 570 were of solid quality.

    Just give it a solid 2.00 volts and see what happens! LOL
    Seriously dude its up to you if u wanna push it that hard go for it,but in all honesty i wouldnt see why u would these cards run everything i have at stock volts.

    Oh I agree for stock clocks most games are just fine but for metro 2033 or even Crysis I find it makes a huge difference with 900+core on the clock. Fermi cards performance scale better than anything else when it comes to overclocking and the card is a completely different beast when its pushed a bit.
     
    I think I will just settle for 950core as the voltage isnt too high and im getting great temps.

    Robs03gtsI was under the impression though that the phases in this specific gtx 570 were of solid quality.


    Indeed, no worries. Split or combined, either way the row of phases on the DirectCU is top-end, bar none. Only solutions that come close or beat it are like the good 8 way 1R1's or a pair of Volterra Digital PWM's.

    Anyway, remember the dying HD 2900's? The memory on those cards were on the beaten path because of the heat coming out of the GPU and the VRM's, the memory got too hot and the card usually died with artifacts. Digital PWM added more heat to the already hot card as well, they might have used Analog to keep the temps low, like how nVidia does with their cards. Analog mostly sucks compared to Digital though. That's one reason I suggest RAM sinks, because you already have hot air blowing on them.

    With my current overclock of 950core using 1.138vc my load temps after a few hours of gaming are 55-60c with the fan speed at only 50%.

    Argh, I thought you were working out. Nvm hehe.

    Zalmans are ok but I'd go for copper instead of aluminum. http://heatsinkfactory.co...ramsinks---8-pack.html

    Sorry, im having a slow day. I do work out, just didnt think i looked that big is all but thanks, heh.
     
    I will look into those sinks as well.

    I realised it upon zooming. The small, bad looking avatar made me think that. I mean, the calves look big along with the upper body. I wouldn't have asked roids if I had seen the arms. BTW, no homo. lol. I just have a habit of examinating muscles as how anyone else who's worked out in the past would do.

    The Enzotech's are pretty, I put them on VGA's, VRM's or even on heatpipes to dissipate the heat better. They're pretty much the best copper BGA sinks out there, go for the Enzotech.

    Haha, nope. I think I'm actualy taller than him, I had bigger arms too. But that was 2 years ago, I stopped working out constantly in 2010. I've lost most of my muscles, especially my arms are shrunk now. Way to go off-topic.

    Yep, you gotta work out on your arms. Your tri's are lacking a lot, but you got good gens: big forearms and frame. I'm 6'1, 200 at most. However, I had much bigger arms at that time. Also, you're 5 years older than me so with better workout you'd have been more succesful.

    Yeah I know bro, I would put more time into it if I could but with a wife and 2 small kids its pretty difficult because my sleep gets all messed up and the kids drain me for all im worth. lol.
     
    I have been battling a very huge bout of depression as well so its really taking its toll, I would like to eventually get back into a good routine with a good diet and im sure I probably will soon enough.

    Yup, those 4 hour sleeps would affect your routine horribly. Because most of the GH is produced in sleep you know, the less you sleep, the lesser your body would find time to build up muscle. Much less you're nearly at your 40, so better get sleep well before you encounter the effects of sleep deprivation. 8-10 hours to say at least.
