btw...Have you saved your BIOS using NVFlash?

By the time we need more then 2gig for normal gaming the next set of cards will be out if that soon. I will then upgrade to 4gigs if needed but right now in this generation of cards it is not for most people.
I feel good about saving $130.00 and having similar/better performance with the classified. pushing the card to 99% today with the new AB I never saw a temp over 55 with 85% fan speed I call that awesome!! yeah , did I also mention I saved $130.00 thumb.gif

whereas with AB 2.2.3 it has offset voltages , your voltage will adjust in respect to the voltage reuqested by the driver...so for instance if the driver goes to .95V at idle, +100mV will give you 1.1V with afterburner 2.2.3. Overvolting with the classified is only viable if you are on water, basically. Personally for 4gb i'd get a couple of 670s or 680 reference 4gb and be done with it.
IMHO, the approach with afterburner 2.2.3 is superior to what EV Bot is doing because it allows offset voltages whereas EV Bot forces a 24/7 voltage and it doesn't not persist after turning your computer off and back on. Obviously, nvidia doesn't want us messing with these things but we still have the original lightning BIOS with ab 2.2.3 so I think it is the better approach.
Of course, you want 4gb so your selection is more limited in terms of what products you can buy. But i'd be hesitant to get classifieds for over volting because the situation with Classy overvolting is not ideal to say the least. Not having offset voltages will result in high temperatures even at idle. Now if you're going water, have at it. Thats the *only way* it will be viable IMHO.

I COMPLETELY agree with you on each of those points!!

If I was not set on 4gb for surround 3d I would as I said have the lightnings and be done with it (2 of em)

But my other choices of 4gb vram give me NO room to play with volts and that just is not fun LOL ... and as you pointed out I will be on water (looks like I will do the universal blocks and save some cash) case has good airflow for the vram and I can always get the FC Blocks at a later date smile.gifsmile.gif

Ok I guess I am off to by the classy's , and I PROMISE I will not be a fanboy LOL I have MUCH love for the Lightnings and their stable voltage lack of Overcurrent protection and their relative great value, great cooler, BACKPLATE that is included and over all awesomeness ... and I have a friend who might take the classifieds off my hands if lightning 4gb's are released and I want those instead , sooooo I feel ready to FINALLY complete my build!

May your voltage run free and high and your overclock overtake the speed of light!

I haven't uploaded the BIOS yet, I will this evening. I will also try to write some thoughts down on how to obtain the best overclock.

First and foremost, I have to stress that temps do get high with increased voltage so until water blocks are available, the best bet is to go with no offset voltage or minimal offset voltage and
find a sweet spot overclock from there. Now the new afterburner allows 300% power which does increase OC stability, this will help some people without additional voltage.
IMHO the best bet for most people is to apply as little additional voltage as possible and find a reasonable overclock using that method. You can also obviously max out voltage but temps will
get higher - and you will have to use manual fan.

I got 1402mhz this morning with 1.3V but i'd be lying if I said temps were kosher - temps were in the mid 70s here.

I was able to get 1362mhz with +0 offset voltage, 250% power, and nothing else changed stable as well and my temps were insanely good. This was an improvement over afterburner 2.2.2 just because the power% is higher, and I did not use higher voltage. In fact, they were so good that I was shocked - in the mid 50s, no higher. My ambient temps are HIGH here, keep that in mind. With additional voltage I was able to get 1392 mhz stable as well.

So I would suggest everyone try +0-+25 offset voltage with 225-300% power, don't immediately max out the sliders, it will cause temps to get high. Try to find a middle of the road voltage and power % , that is your best bet.

I will upload the BIOS this evening and test things some more thumb.gifTo everyone testing, i'd suggesting testing with minimal voltage (start at 0 and try to climb very slowly) and increase your power %. You should get better overclocks than you did with afterburner 2.2.2 even without additional voltage, that was my experience this morning anyway.

Ah dude, go for it. I have nothing against the classifieds wink.gif There's no clause that requries you to hate EVGA when you buy an MSI product that i'm aware of. Or maybe Alex didn't force us to sign it LOL

Let us know how it goes! thumb.gif

I played with the new AB a little at lunch. My cards have never gotten anything outstanding in the way of clocks before, like 1306/6800, but I've always done pretty good in the Heaven 3 and 3D11 (graphics) despite that.

So I load the new AB, up the voltage slider to +60, run the core up to 1325 and mem up to 7K. Power slider to 200, then 300. And my Heaven scores went way down. I never finished a run, I know what the FPS should be at the end of the first few sections and I was way below what I was previously getting so I bailed to save some time. But it was running smooth, not jittery like it does if it's on the ragged edge. I've crashed the thing enough to usually sense when it's about to crater. Definitely not like it was bogging due to too much clocks.

Temps were fine, I enabled all the temp and voltage monitors in the OSD so I could shut down if it started getting hot. I didn't hook a DVM up to the voltage leads, but I know it would have crashed at 1325 before. AB 2.2.3 even showed it running the LN2 BIOS.

Something is not reporting correctly one way or another. I've never been able to even load H3 at 1325/7K.

I'll play with it some more this evening, but this is sort of strange.

That sounds great, actually. If I can find out for certain, that the old Lightning BIOS can flash successfully with the new batch of 680 lightnings, I'll be joining this club by the end of the week.
post #1217 of 7827
Can anyone comment on why a card would start showing a bunch of weird artifacting when flashed to a new bios? (happens all over the screen during boot, in and out of windows, etc.)
post #1218 of 7827
My question is , will the new batch of cards have the same labeling on the box?

ORDERED THEM!!!!!!!!!!!!!!!!!!!!!

If I get 1350mhz and plus 500 mem in 4 way sli I will be VERY happy!!!

Now MSI that I have ordered them it is right on schedule for you to release the 4gb Lightnings this afternoon biggrin.gif
