i just got one of this card and wonder how high can i oc it to??

trying 250/475

it is good in 2d but not good in gaming

screen flickering a bit but no crash

Are you talking about the Gainward card?

I've got mine running at 260/460 with a Blue Orb and Arctic Silver, no problems.

My Gainward 450 is going 215/468 with stock cooling.

 

[heng1028]

got it stable at 240/478

using the stock HSF come with it and thermaltake ramsink


do you guys recommend me to push core speed or memory speed more??

which will bring more performance??

 

[heng1028]

Hender: how come yours can get to 260??

in coolbits the max i can set is 250 only

Yall should try nvmax, goes all the way up to 300 mhz core n 573 mhz mem.

 

[heng1028]

what card are you using?? Xtasy?

Don't worry about the core speed, the card is not fill-rate limited, but memory bandwidth limited. The only improvement you will see by raising the core speed is artificial benchmarks like 3DMark 2000 & 2001. The memory speed is what gives you extra performance in games. Can't remember where now, but a few monthes ago Sharkyextreme, Tomshardware or somebody did a thorough review which included a Geforce Ultra (250/460) and an overclocked Geforce Pro (220/460) and the gaming benchmarks were all equal.

I run my Leadtek GF2 Pro at 230/460 no probs - will run at 250/475 but too many lines and errors evident and the occasional reboot 🙁
