EVGA GTX 590 Hydro Overclock?

[ratclifff4]

Does anyone here think that the EVGA GeForce GTX 590 Classified Hydro Copper can be clocked back up to the stock GTX 580 speeds? I heared there might be an issue with the memory interface or something like that choking or bottle necking its potential to equal 2x gtx 580's.

well if it has similar power circuitry as the reference desing, it will go up in smoke anyways if you try to oc it too hard...

I noticed these are all air cooled though. I'm still curious how a water cooled version will do. Unfortunately so far the 590 seems like it might go down the same path, as far as popularity, that the 480 did a while back. Bummer.

yep they are all reference cards that have been given to reviewers. I'm not so sure whether extra cooling will help, the components seem to fail so catastrophically that it just vaporizes the silicon inside them at the current hotspots... electromigration and all that

IIRC, the OCed GTX 590s that are dieing aren't dieing because of heat, they are being killed by VRMs that fail because they can't handle the load of two GF110 dies. So, water cooling won't make a difference.

In the article here, it's detailed that the cards were over volted more than 20% beyond manufacturer's stipulated voltage limits. MSI Afterburner and Asus Smart Doctor are allowing one to exceed allowable limits.

Ya, the more I hear about these things blowing up due to voltage increases the more I aggree. I've been hearing some of the capacitors on the card are popping. Those things stink and emit a puff of smoke when they blow. I wouldn't know what to think after spending that kind of money.

I'm wondering if the voltage needs to be inreased that much just for 125mhz. (from 675mhz to 800mhz) I run my gtx460 768mb @ 800mhz using Afterburner during gaming sessions with no voltage increase at all. I realize it's not the gf110 gpu but actually it should be less cooperative one would think. Now using Afterburner the vram does get an automatic increase accordingly to the gpu increase and if the vram increase is whats blowing these things up that is a big issue. But then again I'm not increasing the voltage.

When I overclock my gtx460 using Afterburner my video ram gets automatically adusted along with the core. Is that what you mean by VRM? If so is this failure happening without increasing the voltage? That would be a massive oversight on Nvidias part. I overclock my gtx460 768mb from 675 to 800 core. I know its not a gf110 gpu and only single but I thought the video ram on the 590 was 1.5gb of ram for each gpu and only one gpu can use its own 1.5gb of ram and the other gpu has its own sepparate 1.5 gigs of ram with sepparate busses connecting each ram to gpu.

2 GPU's are feeding off 1 set of VRM's so the voltage increase for that 125mhz burst has to be decent

I am unfamilliar with the term VRM. What is a VRM? thanks

Voltage
Regulator
Module

Wholly Crap! That's the weak link? Wow! I wonder if Nvidia can have those replaced. I wonder if it's possible for the average joe to solder on the replcement if nvidia could send one out for free or if there is going to be a recall. Man, Nvidias long anticipated flagship is blowing chunks due to one component. I wonder how they overlooked that. They should've stalled the release date another month and fixed that. Bummer, I wanted one of these. Thanks for the info.

 

[ratclifff4]

Thermal shots of the card have shown the VRM's are hitting over 120C while under load.

I was hoping to use this card as a stock gtx580 for the games that don't support SLI but obviously that isn't going to happen. I'm currently getting my 60fps @1080p x 60hz on GTA4 and Mafia2 at med hi settings with my single gtx460 anyway, so I think that will hold me over until Kepler shows up at the end of the year. Man... I hope they don't drop the ball on that one.
