at what res will you be using this card?

[CrazyNutz]

1650x1050. However I plan to run some test at 1080p

My experience with this card so far is very good, here are some highlights:
1). Very quiet.
2). Very cool. Generates so little heat.
3). The performance is stunning.
4). 1200mhz!!! while gaming and 3d apps
5). Assload of memory OC headroom. I can run the memory at 7200mhz QDR. So I don't think the 192bus will hold it back too much.

[TSXmike]

hmmm... wonder how it would do at 2560x1440.

the OC potential really excites me!

I think that res might be pushing it a bit. Although at that res you really do not need much AA so it would probably be fine. I think I would select a 670 or > for 2560x1440 if you plan on cranking up the eye candy.

Don't think I haven't noticed you only used a resolution of 1440*900 in this bench run More details are also needed such as whats bandwidth like @ 7200. GPU-Z shots would be most useful.

LOL. Not trying to be sneaky It's just the max res of the monitor on my test bench. I will be running some benches with a 1650x1050, and a 1080p monitor. Just overloaded with work ATM.

it is ref PCB ?

I shall be watching.. ninja style. I'm curious to know even with a massive memory OC if the card coughs and splutters once over 1.5GB of its vRAM is full. Theoretically, latencies should go up quite a bit once over 1.5GB vRAM is utilised because of the funkysaurus bus they have on the 660Ti.

disregard

[CrazyNutz]

it is ref PCB ?

Yes and as far as I can tell it is exactly the same as the 670 ref, with the exception of the memory locations.

Yes I aim to test that situation as well.

Nice card Gaul. I'm interested to see what you get your memory clocks to. I've seen some videos where nvidia reps were hinting about the memory OC headroom. I wonder if being able to hit high clocks on the mem will be the norm.

Here's a good review where they have the memory @ 7000mhz QDR:

Looks pretty damn good.

THX and AS u WISH.......
but i really need u'r MAGIC hand to open power limit to 150 % will u ?

Nice! 7200mhz QDR just like mine

Post your bios. I have three BIOS files so far, I'll start looking for the offsets for power limit, and the other fields too. The BIOS's are very different from fermi.
You can use this build of GPU-z to dump your BIOS: http://www.techpowerup.com/forums/sh...d.php?t=170315

thx here GTX 660 ti : http://www.2shared.com/file/pnYQN6yP/GTX66TI.html

and gtx 680, if u don't mind http://www.2shared.com/file/bSCiprqt/INNO680.html

both of them need :
-GPU and MEM leave it stock
-fan 100%
-PL > 150 %
-vgpu > 1.200

[Ket]

Not bad results but once you start to explore the limits of the card you soon find them it seems. Once you go above 1680 or 1920 the card takes quite a steep downturn... not that the results are bad even at higher resolutions, just that I expected better from a card thats still £205+ in the UK and $307+ in the US. This card really needs to come down to £180 or $250 still before its worth looking at IMO especially as GTX670s can be found for around $370 now.

Still would of made more sense to give the 660 Ti a 256bit bus but use silicone with some duff / disabled CUDA cores.

[CrazyNutz]

I won't have any desire to go over 1080p during this card's usable life span. I'm sure they will come down to the $250 price, and actually that is really what it cost me anyhow.

I got the 660ti plus the free borderlands2 that I was going to buy regardless. So $300(660ti) - $50(borderlands2) = $250.00 worked out great.

[Ket]

For you it worked out good and I guess anyone else who wants Borderlands2, but in general $307 / £205 is pretty steep for this card. I'm honestly surprised not many reviews have commented on the price of the 660 Ti it doesn't take much to look around and see for very little extra there is the 7950 or GTX670 on offer, both of which IMO offer much better price/performance/lifespan. Once the 660 Ti does come down to $250 or less though then the story will be a little different. Until then I can't help but look at the 660 Ti and think that its a nice card, but released too late, at too high of a price, and is a little too hobbled for its current price.

Ok man finally got some free time to figure these bios' out. So far i can confirm that I found where the fan range offset is. I modded mine to 100% and it works. Also I think I have found the power limits, and targets etc.. however I have not tried it yet as I need to look through a few more bios' to make sure my findings are correct. Then I will try it on my card.

So for now I modded your 660 bios to unlock fan to 100%. Please try it out to confirm. Thanks

[CrazyNutz]

Ok got the power limit modded up to 141%

@Gaul i'll mod your bios for power limit tomorrow, im out of time today.


I attached my evga sc bios if you want to try. I think it should work on your card

[Ket]

I'm surprised there isn't more interest in this thread the 660Ti is a good card, its just unbalanced, mainly in its pricing. Maybe thats why there isn't more users with a 660Ti in this thread?
