It reminds of money because nvidia cards cost so much.
Heck I would have chose a 580 over 6950 any day, but hardware costs
damn much over here. -_-

2OP- A powerhouse single card is always a better choice than dual cards, so good choice.

To Kung Pow:
1. It's the best single GPU solution on the market without the SLI/CF or dual GPU issues. Slide it into your PCIe and you can forget it's even there.
2. Drivers have improved with last two releases and the 580 is getting more love in the beta 275.60 drivers Nvidia is working on even improving it further. Last cards I owned were two AMD 6870's CF and I couldn't be happier on the move.
3. 3D vision without having to rely on third party software or hardware.
4. You can play all the current games maxed without any problems. Here is a great example of ONE GTX 580 playing Battlefield 3.
http://www.youtube.com/watch?v=2zw8S...yer_detailpage
5. This last one is a personal reason. Nvidia owners don't go over to AMD threads and bash their cards to make themselves feel better about their purchase. We don't need to prove anything to anyone. I've sat and sit on the fence saying that both companies are great. No need to knock them down because others prefer it without real merit in what their posting.

I see you made your choice final from your bio details. Congrats! That Lightning series is a great card, but you knew that. You'll get a nice OC out of it.

Yeah I wanna get my Lightning up to 1GHZ but I am afraid of losing the silicon gamble and getting a bad chip.

I mean you obviously have some experience with the GTX 580.
Is there a limit of high chip´s minimum reachable clock ? no matter how bad they are?

Meaning that if there is a minimum clock ratio for example every 580 should at least hit 900 Core etc?


Also I am not sure if you know your way around the Lightning but if you do could you explain how all the switches on the back are going to aid the oc?
Or if just regulating the voltage in Afterburner will set them all together enabling me to leave the switches alone?

But then again in this video the reviewer says all switches (PWM,Core,VRAM, LN2) are powered individually and can regulate the components individually as well.

I thought OP had a high rez screen, but then I looked at his rig sig and saw it was a TV monitor. Yea that 580 will rape anything your throw at it at 1080p. Good choice although the CF solution does provide more fps, you will avoid microstutter. Plus alot of games do not support SLI/CF at release or has terrible performance in SLI/CF until several patches/driver updates later.

TFIII gtx 580 is a beast of a card

but I prefer ati - they are much cheaper and usually do whatever I want them to do
post #35 of 50
Hey Kung Pow, That was interesting video. Unfortunately I don't have any hands on the Lightning series. You defienetly do your homework. I've noticed that with any of your cards you've owned. I'm going to keep an eye on this thread as you dig deeper into this OC issue. Good work.

Here are some over clock specs I've acheived on my reference card. The MSI Lightning can definetly take it a step further.

My default voltage is 1.0872v which varies from GPU to GPU btw even from the same vendor.

The EVGA GTX 580 SC is 3% gain higher than a EVGA GTX 580 vanilla. So I'm going to post, keep that in mind these below specs from my SC to vanilla. The vanilla flavor can OC just the same btw.

39-40C idle @ stock 797Mhz core / 1594 Shader on SC which is a 3% gain over vanilla stock which is at 772 Core / 1544 Shader. Defaults for both.

40-42C idle @ 838Mhz core on SC which is 8% gain over vanilla stock. 838 Core/1061 Memory/1676 Shader.

42-43C idle @ 855Mhz core on SC which is 10% gain over vanilla stock. 855/1086/1710

43-44C idle @ 875Mhz core on SC which is 13% gain over vanilla stock. 875/1111/1750

44-45C idle @ 890Mhz core on SC which is 15% gain over vanilla stock. 890/1135/1780

To go higher stable I have to bump my GPU to 1.1000 voltage.

45-47C idle @912Mhz core on SC which is 17% gain over vanilla stock.

Now when I OC I bump up across the board for Core / Memory / Shader to be exactly the same percentage gain on each GPU-Z validation.

I got clocked to on my final score front page proof 3D Mark 11 score of 6902. On an i7 950 @ 3.8Ghz OC - GPU 1.1000 voltage @ 912Mhz core.

Anything higher for me failed 3D Mark 11 bench and or gaming froze. I didn't want to push the 1.1000v mark. Though the GTX 580 has no VRM issues I just didn't feel comfortable. I have a feeling the Lightning card can go higher with this same voltage. Hope this is a good start.

Here was another thread a few days back: MSi GTX580 Lightning Twin Frozr III Overclocks . Seems 900/2200 stable with +25mV on the core which equals 1.031v was acheived with Lightning. Someone else had stable at 980 core @ 1.075v. I have a feeling you'd hit the 1Ghz mark with 1.1000v.

Because with that card NVIDIA has like the sexiest card in the world and it overclocks like a dream!

What do you mean you noticed that with any of my cards that I do my homework on them?^^

Nontheless great post!!!
+rep for sue

Because it is unlcear if I I will get a Lightning with a great chip or not therefore win the silicon lottery I am counting on other aspects of my hardware to get the most out of the Lightning.

1.)My mainboard the Gigabyte X58A-OC has two SATA power connectors which induce direct power into the PCI-E slots from the different rails of the power supply meaning this direct power induction should keep the gpu oc more stable and provde extra performance perimeter without the requirement of voltage bumps.

2.)I have heard of 8pin adapter cables that induce double the power bandwidth per pin and should therefore provide a clean power ratio of 1:2 to the individual stats.
That also is supposed to keep a gpu overclock more stable.

3.)The Lightnings 16xphases & good VRM´s should all be able to process and guide all that power induction or course but I am still not sure if it will all work out^^

I will research the individual switches of Lightning a little more.
It basically seems like MSI implemented it from the 6970 Lightning and found other uses on the 580 PCB for it.

Here is what I think:

.)LN2 switch probably releases the voltage cap and lets Afterburner bring the voltages up as far as you like

.)Core switch is probably a just manual voltage adjustment +/- but I am not really sure if the core voltage cap is also released.

.)PWM switch could be just like with mainboards...for example on my board you have the option so switch between 600 , 800 and 1000+ PWM voltage but the manual clearly says not to go above 800 without LN2

.)VRAM switch again could increase the voltage to the VRAM and release a cap.

Since you can only adjust the core voltage in Afterburner I am wondering if a manual voltage increase of VRAM and PWM will really aid the overclock.

What the LN2 does is still unclear.

I have already contacted MSI about it though.

I don't have the 580 lightning yet, switches should be similar to the 480 lightning though (not sure which ones the 580 has).
I haven't frozen this 480 yet so haven't used all the switches. The vcore switch adds 0.1V on the fly, I haven't used/measured the vmem or pll V switches yet but they also boost voltage, the pwm will boost the clockgen frequency & the OCP disable is pretty self explanatory.
The ln2 switch is probably to switch to the second bios which is modded to avoid coldslow (when at about -80° without a coldslow mod framerates suddenly drop to a slideshow). On the 480 lightning it is called the bios switch instead of ln2 switch, but can't think of anything else that makes a big difference with ln2.

I cant give you nvidia love,but I can give you single gpu love - it's always better to buy single,faster gpu then 2 slower (which are faster in sli / crossfire )
Microstuttering in one reason.
Not good scaling in a lot of games is another.
Much more heat/noise/power is third
As for some people commenting that 580 is gonna handle anything you throw at it at 1080p resolution,I disagree. There are couple of games which even 580 sli cant handle at constant 60 fps.
For example I have 560 ti and I got 18 fps in some scenes in metro 2033 fully maxed. For a 580 to deliver 60 fps,it would have to be 330% faster then 560 ti. I somehow dont think this is the case
Hell even to deliver 30 fps it would have to be twice as fast as 560 ti...

I have had no issues with micro stutter with my SLI setup. That being said, the 580 Lightning is better than 6950 CF because of Physx, CUDA, driver support, and better game support...
