Ok thanks I'm sure the video will help me out a lot!

The mod bios is probably still in the KGB folder and you are asking nvflash to look on C:\ for the file

My aquacomputer MSi GTX680 lightning block arrived today, thanks Gary @ Sidewinder for shipping out the item in the middle of a blizzard :up:


It really is a work of art. I'll let the pictures do the talking.









And this one just for fun after I mounted the card in the upper slot for the first time




And of course results (after full round of 1000 tkt BF3) @ 1293c/8002m






Full load ends up being ~40-42*C core, 35-37*C mem, 45-47*C VRM

Shaved about 30*C off each component and best of all as you can see in the shot above, mem is now fully stable at +1000 MHz (on stock mem voltage) giving 4001 Mhz or 8002 MHz effective and 256 GB/s bandwidth.

Make sure you put the nvflash files in your C:/, along with the BIOS file. Make sure you open nvflash by right-clicking it and going to 'Run as Admin'. And, of course, make sure you type in the name exactly as it appears. Name it something simple when saving it, like Unlocked3A.rom. You should be good after doing all of that and following the directions in the first post (except the part where you enter the filename. Enter what you named the file instead of typing the name used in the example, unless it's the same of course:)).

Beautiful. That sounds...too good to be true. I mean, it's possible you got a card with the most perfect memory out of every Lightning out there, but +1000mhz on the stock voltage blinksmiley.gif I hope it's working fine and everything, just seems waaaaaaaay above even a golden chip. Oh well, maybe you got a platinum chip biggrin.gif

I'd love to see what the memory can do once you start increasing the voltage. Plan on doing that soon? And is that the highest core you get with +93mv or is that at stock voltage too?

It's 100% legit running +1000Mhz. I've even flashed it to run that now so I don't need to use software as you can see below I just took a SS of GPUZ for you. You can also see the flat line at 4001 MHz in the AB monitor graph in the post above where I was gaming. I was surprised, I mean I've tested 4 lightnings now and this is by far the best in terms of mem and also has the best core of those I've tested (although nothing like the golden core chips like yours and the guy running 1475 above).

1293 MHz game/everything stable is with the bios flashed to 1.1875v giving ~1.24v loaded. I guess it's a decent clocker, just gets put to shame by the likes of yours.

When I was testing this on air it was stable +900 stock voltage, but took a bump of +10mv to get +1000 stable and I wasn't liking the temps so I backed off until my block arrived. It seems to do 4050 (8100) ok on stock voltage but given how much bandwidth it's pushing now it's probably at the point of diminishing returns. I am happy with it where it is I think, although I am curious.

Hardly! You got a great one, no matter what anyone else's does. 1293mhz at 1.24v is great. You got a lot of room. Go up to +93mv and with your waterblock you'll probably be right around the 1430mhz I can get with that voltage. I only ran 1480mhz because I had the voltage up to 1.42v (roughly +162mv on the core). You could run that voltage easily and with the much lower temps you'd probably be right on par or surpass mine.

And no one can touch your memory, so, you got one of the best cards here. I would envy no one's card if I had yours thumb.gif


Edit: What the hell happened here? Is this the new .90 drivers? I only had my internet browser open, and then I hear the fans revving up. I'm like...what's going on. I look at Afterburner and see this-


Did a scan, don't have any viruses or malware or anything.

Thanks for the kind words. It's easy to have core envy when someone else's seems just that bit better than your own!

I am worried about GPU degradation running higher voltages for extended periods. I mean its a 28nm wafer running upwards of 1.30v must be pushing the limits of the silicon before electromigration and hot electron injection becomes and issue even with ~40*C temps. The VRM is up to supplying that much power no question, its just the silicon I am concerned about.

EDIT - what does your PLL measure at when loaded?


^No idea mine didn't do that on the 310.90's I was aircooled until this evening. It did switch to P0 state a couple times when opening things though just not on its own.

Not sure, don't have a DMM.

Well, I've been running mine on the LN2 BIOS most of the 6 months I've had the card. I run the good card at 1.36v more and more often because I just got into a few games that hate SLI so I OC the hell out of the good one for the best framerate possible. Sometimes even run it at more than 1.36v. Like with a slight bump up to I believe the next increment is +99mv or something like that, I'm rock solid in Hitman at 1424mhz/7000mhz (max temp of 65C wink.gif). Been doing things like that for a while and I figure I might as well enjoy the card now since I know I won't have the will-power to resist when the 780 drops. So, I used to think exactly like you did, but then I figured, I paid all that money for this card. I'm going to enjoy it before it's too late.

Your decision makes sense though. I completely understand. And you have much more will-power and control than I do. Because every time I need one card now, I crank that bad boy. Good news though is no degradation yet smile.gif

I know you're right in that way, every time I buy new tech my old tech is still in immaculate condition. I was running my 990X at 4Ghz @ stock vcore until recently and bumped it up to 4,4GHz/1.26v for that exact reason you mentioned - enjoy it now or it will be like all the others. Im not even pushing it truth be told and its on water too so it'll be around for awhile yet. Good news about no degreadation for you so far, if I crank mine up and run it hard I should at least be able to get past the 780 launch date!
