I have the fan profile set on the MSI to silent and it never goes above 50% fan. Twin Frozr III cooler is impressive.

The Evga GTX 560TI 448 Classified is one of the most impressive cards I have experienced for the money and I have owned most of them during benching competitions. I am able to clock to up to stock GTX 580 settings without a voltage increase.

For the money, I prefer it to my GTX 580.

I was not impressed all with the original 570's with only 4 power phases. I had to RMA an Evga card because of a mosfet failure.

I attempted the 962/1924/2100 @ 1.1v on my EVGA Classified...

Woot!

(my stock voltage was 1.013v)

got mine today.

320

it came in a ESD bag i just took it off for the picture so you can see the card.
my water tubes are in the way so i actually need to disconnect a bunch of stuff first before actually installing it.

dam i would be happy with 900mhz at 1.05v.

I'm very new to overclocking.

I have the EVGA Classified card. I put my frequency settings to 900/1800/2270 @ 1.1v. I ran OC scanner for 1 hour with zero artifacts. Temperatures hit 72c with 82% fan speed (very loud). Are my temperatures okay? What about the voltage? Can I increase anymore? Are there other tests I should run? I have my fan profile as a y = x line where y(30) = 40. In other words, from 0 to 30c, fan speed = 40%. From 30c to 90c, the fan speed increases linearly with temperature (40% @ 50c, 50% @ 60c, 60% @ 70c, etc).

My persona fan settings:

40C - 51%
50C - 62%
60C - 73%
70C - 84%
80C - 95%
90C - 100%

As for over clocking a good 24/7 over clock would be 15% Core / Shader and 5% Memory. (I've had mine since February 24/7). I think you have your Memory OC too high. Memory shows little gains in performance with greater temps and less stability. You'd probably get higher Core / Shader over clocks by lowering Memory and see greater gains in performance with less heat.

You might also want to bring down your voltage to stock and try this OC bump first. If it's stable then your temps will go down even further. Voltage also plays a role in GPU temps.

With same 5% Memory over clock I hit 950Mhz Core / 1900Mhz Shader for my highest bench. Just some food for thought. Good luck.biggrin.gif

That seems like quite a high voltage for 900Mhz, did you test that speed at lower voltages first or just crank it up to 1.10v? What is your stock voltage? Your temps are well within range, but you may be making it hotter than it needs to be with that amount of voltage for that core speed. Most people I've seen here are running @900Mhz with anything from their stock voltage (around 1.00V) up to me with1.088v. fan profile sounds fine, but that's of less significance to the oc and more of a personal preference. The cards downclock themselves when they get around 95C if I'm not mistaken. Best way to test the oc is to play some new games, BF3 is a great way to test. Also 3dmark11 is another good test/benchmark.

Edit: oops ninjad, and didn't notice the memory oc. Listen to Arizonian, he knows his stuff!

question about the airflow..

im using a micro ATX board and the pci-e slots are really close together. i also have the XFI-HD sound card and it gets in the way of the air intake of the graphics card.

my gtx 260 didnt have that problem because it is a blower type on the right.

i can wedge something in between to give it more space but its 3/8" at most in front and a lot more narrow inside.

450

will this effect my temps dramatically?

i would use the bottom pcie-16x but its a microatx case too and the CPU is really close. also i wont be able to hit the bios reset button

Edit: oops ninjad, and didn't notice the memory oc. Listen to Arizonian, he knows his stuff!

My stock voltage was 1.038. I tried to run 900/1800/2270 at 1.038 and got a lot of artifacts in OC scanner. I saw some review a website did that did 900/1800/2270 @ 1.1v, so I just followed suit. What should I start by doing? Lowering voltage from 1.1v down until I get artifacts in OC scanner? Bring memory clock back down to 5% increase?
