Im running 1320mhz on the core and 1800mhz on the memory stable now smile.gif
But again, remember to keep fans spinning when raising voltage! u want good cooling and airflow.

Speaking about fan speed increase. I posted this in the 660 (non ti) Thread..

Well... i ran the benchmark again without my custom fan profile just now. Although my top card in SLI went up to 73c, the low fan speed made the GPU's not throttle as much... And it seems like the higher the fan speed, the more the card throttles redface.gif.... I think you guys should try this, and report with results if you notice any change too..

This is what i got before with custom fan profile. I have run this multiple times, but sometimes i even get lower scores. Warning: Spoiler! (Click to show)

This is what i got with no fan profile, just the GPU doing it's work; also ran multiple times. Warning: Spoiler! (Click to show)


i also noticed changes in games... 3d mark 11, i got higher graphics score, and Sleeping dogs, about 10 avg fps, even crysis 3 Warning: Spoiler! (Click to show)

As in my above post I saw a similar issue with fan profiles . Stock , no OC no fan profile my card would hit 1202 @ mid 60's .

I installed AB and made fan profile which kept temps around 55-58c and the card ran only 1189mhz, remove fan profile and it back up to 1202 .

As I mentioned before I rather keep it cool and just bump core clocks to whatever I want ,you just have to be careful to not hit 61 or clocks bump up 1 multiplier (13mhz) .

Hello everyone,

I got my problem fixed ! it wasn't the power supply , well i still think that it's not enough but it works Ok .

i changed the physics in the nvidia driver seetings , from AUTO to processor and all went fine. no more error " inter turbo boost" , i tried to OC a little bit and it 's OK .

Thank you very much for all , and i hope it will help DELL XPS 8500 owners.

Hey guys, what does a 660 TI need to be overclocked to so it can match a stock 670?

That will depend on app/game, resolution and AA settings . higher the res and AA the harder the 660ti will be to keep up with 670 .

But overall you need pretty high clocks on both core an mem . if you can get 1250+ and close to 7000 on mem looks like its close .

Hi, i have a MSI 660ti PE and i tried to unlock the bios but i cant run the bat file,it says not a valid win32...What is wrong and is it worth it to do that?

Try it the normal way without unneeded batch files etc, I never understood why people made the process more complicated..

http://www.xtremesystems.org/forums/showthread.php?284014-KGB-Kepler-BIOS-Editor-Unlocker

and is it worth it? Up to you to decide, be aware that when you unlock voltage, your max kepler boost may increase beyond stability.

Yes but you will also be able to run on 1,212v which will make it stable on higher clocks!

I have it all stable on 1320mhz and 7200 on the memory.

But i had several stable runs in Unigine Valley with 1359mhz on the core.

most important is to keep all cooling going, since not every little hot part has their own temp monitoring.
