Finally some help for my Lightning

[pgi947]

About 1280mhz mate.


Hitting a wall now @ 1420mhz @ 1.51v!! Well thats what it shows in AB/gpuz

temps at these volts
pcb 28c
gpu 48c
crap memory 32c
vrm 42c
water temp 25c

got a little more volts yet, but i'm gonna wait till mrs goes to work in the am and get the windows wide open.

Thats mah boy

Still 1420 is very very very fast!!

Scaling may be around the same for me then, just ran a small bench at 1306mhz (over two cards!) 1.21v

Unlucky! Thought it would have scaled with the extra voltage.

I already knew my max on air, so i pushed the core up, then once my bravery ran out i tried upping the mem.
The sweetspot on the core felt about 1400, so i may go back to that and try raising the mem from there. Had upto +225 stable at a low core. Few things to try yet.

1400 was achieved with 1.41v so a massive increase in the voltage to get that extra 20hz.
When i get more time i'll have a play with different drivers too.

1400 on the core is going some though. So far so good.

Ha ha yes thank you paul for putting me on the right path to moooaaarrr powahhhh!!

It is fast, but that ******* memory is hampering scores big time.

Yeah you should be able to hit 1400 at "safe" volts

1400!!!! Really good job mate. Congratulations.


And given that clock for clock the 780 beats the 290X on everything but BF4, nothing can come close with 40% buff.

Nice Nick and more volts doesn't always mean more score. Trying for 1400Mhz and slightly lower volts could pay off. I remember the more volts I gave my 680 Lightnings, the lower the score, so was fine tuning to get the best possible.
