I figured if it didn't freeze or ctd it would be fine.  Guess I gotta bump up the volts even more...

No problem, is yours different?

I'll just be bumping my post on the last page.... 

- Reading about all of the overclocking limitations I'm starting to wonder if I should only buy 2 Classy HC's. I was thinking of 3 since I gaming on a 5000x1080 resolution while using Stereoscopic 3D. I wonder how much impact the 3rd card will have on the framerate when the clocks can't get as high as wanted?

Surely this has got a relatively easy answer....

 
What kind of clocks did you want? 1400's on air and more on water not good enough? And yes, a third card will have a significant impact.

While I don't have EV Bot I think nobody at ALL is going to use the classifieds at 1400mhz on air.   Apparently EV Bot doesn't do offset voltages and that is a HUGE flaw in my eyes, who wants to run 1.325V 24/7?  Thats insane.    Thats a big caveat in my book, its great for benchmarks but I can't see myself doing productivity work 24/7 at 1.325V....
 
I'm happy with 1290mhz on my 2 classifieds.   Big 3dmark11 numbers are nice, but EV bot doesn't make it practical to use those speeds in real world usage.

Is it easy to toggle between default and say 1.325V? If you have a profile set at .9V wouldn't that lock the cards at .9V, causing instability if they tried to ramp up for any reason?
 
It wouldn't be too bad if you could toggle easily between default and Profile 1.

1. If you don't have an issue running that voltage while benching, you won't have one while idle or in game. Is running .3 more volts in a gpu detrimental to the hardware? Definitely not, especially if temps are under control.

2. You do realize EVBot has presets, right? So your preset 1 could be 1.3v for gaming and benching, preset 2 could be .9v for idle. Preset 3, any mix of the two. Am I missing something that makes pressing one button real difficult?

 
 
No andrew, thanks for the clarification.  I was  under the impression that you cannot do this from the anandtech review.
 
Can you explain how the voltage switching works? Can you do it on the fly?   From my grasp of things, is that driver requested offset voltages will not work with EV Bot, correct me if i'm wrong -- once you set a voltage you stay there -- Normally when you go to idle your card automatically does .95 volts.    When at full load it goes to 1175mV.   Now with EV Bot, is this not the case?  Do you have to press a button on the EV Bot for it to work?
 
In any case, its another hassle, but I really would appreciate any clarification.   So you can do up to 3 different voltages, but you have to enter it in EV bot each time?  Do you have to reboot or just press the button?   Does it work through the driver?  To me the anandtech review made it sound completely not worth it, I definitely don't want to idle at high voltages.    But again - I would appreciate any clarification.  I don't have EV Bot yet.

It would really help for EVGA to release some sort of documentation clarifying all of this for potential buyers.
 
Basically, with the EVBot voltages are adjustable on the fly, as you probably know. The voltage change does not appear anywhere within windows (not GPUZ, not PrecisionX, etc.) As easily as you can raise the voltage, you can lower it. Infact, this is one of the bigger benefits I've found with using EVBot. You can run a benchmark (heaven) at a specific clock speed and voltage, and as the run goes on you can modify the voltage in small increments to find the lowest possible voltage that will run it stable. Huge benefit.
 
Regarding the ease of control -
Making changes in the EVBot requires several button presses, first to select which card you want to modify, then which voltage (core, mem, etc.), and finally a button press to raise or lower and to save that value. This is more for the tweaking process. Once you find the perfect combinations, you can save them to one of the preset buttons, which will save all of the settings across GPU1-3. This allows you to later go back and press 1 button to load up that profile. (see EVBot diagram)
 

 
 
Thus, you can have one profile for Benching (presumably max voltages), one for gaming (the perfect combination for speed, heat, noise, etc.), and one for idle (low consumption). The settings themselves don't stick after a hard reboot, but the profiles do... ultimately making it a very simple process.
 
 

Is there a default button, or a quick way to undo the voltages without a hard reset?
 
What I'm thinking is I would have one profile for gaming, one for benching, and run default if I'm not doing either of those two tasks.
 
Is it very simple to go from Profile 1(gaming profile) back to factory settings, or does it require a hard reset?

I think in that case you would need a separate profile on the EVBot that is saved from when everything is on their factory settings. I might be wrong, but that's what I am doing with mine.

I'm really glad you shared this info Andrew.  The AT review made it sound like EV Bot was a bad idea, but your post cleared that up quite a bit.  I'm going to buy one, I would get it from amazon but i'm worried that it won't be flashed.....off to EVGA store it is

 
Definitely worth it. I'm not sure why Anand made it sounds more complicated than it actually is. Plus, without doing any physical mods to your cards you really won't be in any danger of pushing them too far, with the voltage ceiling at 1.35v. Perfect for getting more out of the cards, and having some fun tweaking at the same time ;)

Soon I shall have these under water pushing 1.35 24/7 if possible.  Need more performance.  =)

What settings are you running that you are getting 1400 Stable ?
 
Sure you can get to 1450+ but that's just in precision, soon as you test it with the EV test (old furmark) it throttles.

If you only knew... 

But PRETTY pictures ;)
So there are 3 of us here with 4 of these each NICE!!!
 
Andrew thanks for clearing the evbot up for people , I actuallt think it is fun to use and looks NICE!
 
BTW andrew how high are you able to make it up in voltage on your cards before you hit the power limit I am getting PRETTY close at 1.31 - 1.325v and at 1.31 ish with an overclock of 1380-1400 and memory at plus 600 or so I get peaks at 127 or I think I have even seen 130% GASP!
 
I am still contemplating the HC blocks or universals ... if we could hit 1.35 - 1.4 without hitting the power target or over current protection I would be VERY willing to drop $600 + on 4 HC block's hint hint Jacob , otherwise I will deal with the looks and complications of LOTS of copper and universal's ...
 
I will be away from my rig the next week so won't have time to put all 4 cards in the rig together till I get back ... so that is a week to give us with HC waterblocks a tad more voltage ;) or rather to let us know if we shall buy we shall recieve wink wink Jacob... not asking 1.8v here just the ability to hit 1.35 - 1.4 without throttling maybe a power target of say 200% , now I would PAY for the HC's if that was part of the package, WHO ELSE HERE WOULD DO THAT TO?

Finally got my 4-way setup with my EVBots (bought 2 so they could be permanently installed). So far, just running 1.25v...

Pretty nice boost clocks and temps (set at 131/100/400/1.25v)...here's Battlefield 3 multiplayer (5760x1080/120hz) on a 64-player map.

And a nice 3DMark 11 P score...

Sorry for the image SPAM. I'm new so I'm not allowed to post links. My full blog post is at 1pcent.com if anyone is interested in details. Loving these cards!!
