Man dude, it doesn't matter I think.

I believe everything has a limit..

Take a gpu core for example, specifically my 448's, anything above 970mhz no matter what voltage and temperature, it crashes 5 seconds into any game with temperatures not breaking 60 when it happens.

Dude, don't kill your card.

Not running 1.213v 24/7, just for benches...
at 1.1v, my cards can do 970 bench stable. at 1.213v, they are 100% stable at 980. But anything higher i get crashes very soon after launching... Voltage doesn't do a whole lot... 24/7 I'm running 1.050 (stock for 2/3 of my cards) at 833mhz core. Gotta keep the heat down a bit since I've only got 3x120mm rads cooling cpu, mb, and 3x gpus.

I used 30mm bitspower extenders - 1/2" ID.
each card also got a pair of bitspower mini 1/2 quick disconnects
The sli bridge thingy is swiftech... it just plugs into the gpus via the quick disconnects.
It's a TIGHT fit, but it does all fit with a little bit of breathing room all around.

I don't know if max voltage setting will hurt the card but I think more importantly is that you find the fastest lowest voltage setting that your gpu is stable at. That is the sweet spot.

My card will run at 1.1GHZ at 1.16v on the core. I can go higher in voltage but it's not needed. Also I can't go much higher on GPU speed. I'm right at the limit of my GPU with the lowest voltage setting needed to maintain stability.

I'm sure with extreme cooling like liquid nitrogen I can increase the voltage more and increase my GPU speed but I believe my water cooling is limiting greater over clocks.

No sense in running more voltage if it doesn't help your gpu increase speed and increas performance while maintaining stability.

Found a new sweet spot for my card at 1.1GHZ.

First time pass on Vantage at 1.1GHZ, 1.16v

Just bench marking. smile.gif

Also after further tweaking I have been able to stabilize the core speed at higher speeds while reducing overall voltage.


Just figured out some stable voltage settings for 1.1GHZ stable runs on 3dMark11. GPU core at 1.175v.

Hi guys
Been following this thread for a while, as I have been considering buying a 560 448 and I would look some advice as most of you guys seem perfect for that!
Anyway, I live in Denmark so the prices are not all that coherent with those in the US, i.e. a little more expensive. So basically the choice comes down to a few choices.
I have the choice between a 560 ti 448 twin frozr III where the price sits at 1982 kr (348 USD), now this was my first choice because the reviews I've seen have been excellent, but recently the price has gone up which is pretty sad. The 2nd choice is the Asus variant of the 448 which sits at 1699 kr (299) USD, reviews for this has been a little worse than the MSI variant but still pretty decent. And the last choice is the 570 card from MSI which sits at 2101 kr (369 USD).
Basically my question is, is the high price for the MSI variant of the 448 worth it over the Asus 448? And would it be even better to get the 570 performance wise for a higher price?

Thanks in advance!

MSI cooler is very worth the extra dough. Although right now because of kelper, I'd wait for the replacement if I am you.

Thanks for that info. I purchased 40mm extenders for a bit more space. I also purchased a Swiftech SLI connector, they look nice and are a lot cheaper than I expected. I will finally be able to close my side panel on my Phantom case biggrin.gif

Originally I bought 40's, but they were too long, so I sent them back and got some 30's. The quick disconnects are ~12mm thick, so the 30mm + 12mm = 42mm, which clears the edge of the card by about 7mm.
