Nice I think I should be gtg then was worried that I wouldn't have enough ram on the cards to do the nvidia surround. Hopefully after spending all this money ill be good for a few years. Thoughts?

If you got 2gb models you will probably struggle in surround vision really that's where the 4gb shines. Two more screens is going to require more memory so you may have to drop aa and other setting s to keep it from maxing the vram and causing stutter.

The Lightning would be my first choice, then EVGA Classified would be second choice. If you want to unlock the GPU yourself and save a little cash, i would go for the ASUS DCU II 770, and hot wire it like 66racer did, then second choice would be MSI gaming 770 with MSI afterburner volt mod. All other 770 versions fall behind the ones i mentioned earlier tongue.gif.

Hey everyone !

Would like to join the club smile.gif Bought a Gtx 770 Lightning from MSI.

There she is in all its glory next to my old gtx275 ! biggrin.gif



Tried Overclocking it and what i got, on stock voltages, is 1293 (Boost) Core clock, 7,6 Ghz Effective memory clock.

The software i used was MSI Afterburner 3.0.0 Beta 18 ( The gpu "Toggle" on the card itself was on the Normal BIOS and not the LN2 one).

After i got that, was curious what this bad boy could do with say an extra +50mv to the core voltage.

Unlocking the voltage was simple enough ( I guess ? ). Went in Afterburner's Settings and under the General Tab i ticked Unlock Votlage Control and selected extended MSI from the Dropdown menu to the right of the tick box.

Now here is where things get tricky. With the Dropdown menu set to Standard MSI, +40 on the core clock would yield the maximum Boost clock 1293. If i set it to Extended MSI, the same +40 on the core clock gives me 1280 Boost.

Anyone know why this is happening ?

Another curious thing would be that : If i enable the Voltage monitoring under the monitor tab, Afterburner reports the correct voltage, BUT WITH A HIGH DROP UNDER LOAD. Say, i set the voltage to +70mv, all is well and dandy in the idle phase, but when i load up Heaven Bench or a game, the voltage drops to ~~1.23 - 1.24.

This drop effectively means....i have to set the voltage to +75 AT THE VERY LEAST if i want to keep the 1333 Mhz Core clock (at the 1.24 voltage with the load drop) .

I would like to game at 1333Mhz clock. I know that, in order to keep this OC stable, i need 1.24. Would running 1.27 at Idle damage the GPU in the long term ? My assumption is that because of the beefed up power delivery system & the millitary Class III components i should be fine.

Would love some feedback on issue 1 and 2 ^_^ !

Nice card! Are those clocks your maximum oc and is it stable?

What brand it is? Normally by removing the heatsink you can see which voltage regulator (VR) is uses (some pcb's have this VR on the back so its easy to identify it).

its the nvidia branded card.
unless someone makes a custom bios for the reference card then i may not get overclocks
