[BenchBros] MSI Lightning hits 1665 MHz ... 181580 3DMark03

[Kabauterman]

Hey guys,

today we give our good Lighting another try.

Last time together with SuicidePhoenix we could achive outstanding 180k in 3DMark03 but not more coz of running out of LN2...

This time we started with 3DMark03 and our goal was it to top our last score with our own new CPU. but we've seen that it is hard to compansate 200 MHz missing CPU Clock in 3DMark03 ...

Setup:

Intel Core i7-2600K
ASUS Maximus IV Extreme
MSI N580GTX Lightning
Corsair Dominator-GTX2 2x2GB
Corsair AX1200W PSU
Csorair R120 SSD

Cooled by Ryba's Fat Pot!

Card is OCP modded, Voltage was GPU +500 mV (1,55V) and Memory +170 mV (1,8V)
Temp: full Pot unter Load

1665 MHz means Stock (832) x2



still third place but a lot more impressive we think... this is the absolute Max of this card, more voltage didn't help, it's just more hard to handle.

So we are looking forward to the next session together with SuicidePhoenix 5930 CPU + 1665 GPU = 184k ?

-----------------------------------------------------------------------------

Thanks to MSI, ASUS and CORSAIR

Insame gpu speed! Well done!

[M.Beier]

Benchbrot strikes once more and again!
Congrats on the amazing score!

[l0ud_sil3nc3]

very nice job guys

[George_o/c]

Breathtaking frequency guys, I was sure you would find a great Lightning again! Once again, you made news http://www.hwbox.gr/news-h-o-t-hwbot...n-resital.html

Very nice result, guys!!! Need more cpu power!!! Run with SuicidePhoenix`cpu!!!

[zalbard]

115% GPU overclock, insane!

[Gautam]

Well, I'm glad you didn't take out stummerwinter's score. No one wants to lose a WR on their birthday.

[Kabauterman]

115% GPU overclock, insane!

it's just 100% + 1MHz

coz Stock Clock (Air BIOS) of the Lightning it 832 MHz just in the LN2 BIOS the Clocks are reduced to Reference Stock

[Splave]

nice! so you did OCP further then the switch itself?

[loopy83]

Yes... we need OCP mod past 1650Mhz and 1,55V.
1700mhz crashed in GT4

[dejanbinladen]

finaly great frequencies wtih lightning

[George_o/c]

Yes... we need OCP mod past 1650Mhz and 1,55V.
1700mhz crashed in GT4

Make two profiles in Afterburner. Bench GT1, GT2 and GT3 at 1700MHz, then press the shortcut key for Profile 2 (whatever key you assign for profile 2) while GT4 is loading and bench it at 1665MHz

[Kabauterman]

Yes... we need OCP mod past 1650Mhz and 1,55V.
1700mhz crashed in GT4

I think it was Troll's Lair when the Troll's start to fight...

Goerge, we will give it a try next time, maybe some more fps in GT2 are possible. But better CPU will give it a very much higher Kick

Nice Lightning action

[Wumpus]

now thats sick lightning!

awesome scores guys

[vern]

Xtreme overclock
116% overclock

[Kabauterman]

It's 116% over Reference card, but "just" 100% over Stock Lightning

[Gunslinger]

Yes... we need OCP mod past 1650Mhz and 1,55V.
1700mhz crashed in GT4

What are the signs of an OCP issue?

I was testing another Lightning card today, when vgpu touched 1.55 under load, the red and green pcb lights would go out and vgpu would drop to .228 and it would need to be powered off to restart.

[dinos22]

seems like you are experiencing OVP or some PSU issue probably gunslinger

if it is PSU, the System will shut down fully

if it is OCP you got a Black Screen, Voltage of the GPU goes to 0V
If you just have Clock issues the voltage Stay at the Value what you set before.

So your's sounds like OCP.

1.55V is a lot for the lighting, maybe you don't need so much, I think lightnings need's 0,1V less then DCU's for equal clocks.
