Just wanted to say that in my experience Kombustor/Furmark are near useless for confirming 6xxx OC stability.

Instead, just play something demanding or run Metro/Warhead benchmarks etc...

I agree. I run Kombuster to do a quick check. If it passes the I will load Bad Co.

Just played over an hour of Starcraft II with core at 970 and memory at 1375 on stock volts with no issues. I meant to put the memory at 1475, but somehow missed it. Temp on the GPU topped out at 65 with the fan on it's auto setting. Never really heard the video card over my other fans and the game.

However, I set the memory up to 1475 for 970/1475 and ran Kombustor Extreme burn in and got the same results as you. I'm quite disappointed in that. My Sapphire could handle more than that with no issues other than sounding like a jet plane taking off. However, I'm going to RMA that Sapphire. This lightning may not clock as high on stock volts, but at least I can hear myself think. I hope this thing really shines with with higher voltage. Tons of power phases, but with a worse GPU?

You know, maybe you just got lucky with the Sapphire...

Overclocking is not rocket science, nor is the process of "binning".

Binning is not really as crazy as you guys make it out to be.... let's take MSI's GTX560-Ti for example.

NVIDIA sends us 10000 GPUs. We test them

Tier 1: meets/exceeds testing for 950MHz core. We use it in Hawk.
Tier 2: meets/exceeds testing for 900MHz core. We use in Golden Edition
Tier 3: meets/exceeds testing for 880MHz core. We use in Twin Frozr II factory OC version
Tier 4: meets/exceeds testing for 822MHz core. We use in base reference-speed cards

THAT IS ALL.

Can your GPU overclock to be world champion, if it's out of the box and reference clock speeds? Yes it's possible. But the CHANCES and PROBABILITY that you can do that with a reference clocked GPU is much lower than versus a higher clocked GPU.

That, in a nutshell, is the process of "binning". No one "cherry picks" GPUs, it's much too time consuming.

Alex, thanks for that, I didn't think that there really was a 'cherry picked' chip.

As you said, the highest rated chips go to the higher rated card.. My Lightning has maxed at stock voltage, 980/1410. I tried 990/1420 but it crashed, I upped the voltage from 1174 to 1180 and it failed/crashed on test 22/26 on unigine.

There are several reports/reviews of this card doing 1000/1500 at stock voltage. I had hoped for the same result.

I already explained that, but it is nice that MSI does have some information about it somewhere.

@Spct
As for 1000/1500 at stock voyage... where did you see that? All the reviews I saw need more voltage to get to those clocks. Also when increasing the memory clocks did you also play with the separate memory voltage slider?

This card may take some serious tweaking to get a good OC -- especially since there are three voltages.

Even with the middle BIOS, I'm having trouble figuring out how to unlock the memory voltage slider in Afterburner. Regardless, with my other card, I found the memory to be the limiting factor. 970/1500 was unstable. 970/1475 was stable.

I will look for the reviews for the 1000/1500.

I did find this one, http://www.overclockers.com.au/image.../948935/26.jpg

Increased voltage. Im gonna try it now.

Thanks for watching these forums and posting. It's nice to know MSI is looking out for us.
Hmm, the "triple overvoltage" is clearly advertised on the box. I wonder if the afterburner version on the CD or at MSI's site (written on the CD) will work better than the beta version from GURU3D.

@MSIalex
If you are still reading this, do you have a comment on this apparent conflict with the advertising?
