overclocked gpu

[daz7189]

im wondering is it worth it?

i oc'd my his ati 5770 gpu from 850mhz core an 1200 mem to 1000mhz and 1300


theres a benchmark test in just cause 2

before the oc the average fps was 30 after the oc it went upto 33fps


thought i would get a little more than a 3fps boost


tbh though from about 920mhz i see no improvement in fps at all


just wondering what u guys think


thanks

It depends on the games you play/things you do. If you see animprovement in them, then overclocking is worth it. If you can't visibly notice a difference, then go back to stock clocks.

cool thanks for the info

think i will keep it at 930mhz because compared to 1000mhz there is no difference at all

exept a higher voltage and higher temps

Sounds about right to be honest.

You have to bare in mind that Just Cause 2 is a 'fairly' demanding game...3fps increase might not seem much, but going from 30fps to 33fps is actually 10% increase in frame rate

Seriously, if overclocking low-end graphic card would give you 10fps increase in demanding games, then I can't see how the mid to high end graphic market would be making much money at all

but is it visible??

but is it visible??

When the frame rate drop to below 25fps, every fps counts and does make a difference

Take 22fps vs 25fps for example, the difference is VERY noticable.

But i'm talking about 30-33
It's only visible in fast bits. I doubt it's worth extr heat and noise though

cool thanks for the info guys

10% boost sound so much better than 3fps


its funny though when i overclocked and unlocked my phenom 555 be i went from an average fps of 19 on the same just cause 2 benchmark after the overclock it went up to an average of 30 fps pritty amazing that one made a big difference


thanks guys

What cpu do you have. That could be bottle neck your card and that's why your not getting much out of your clock

 

[daz7189]

got the amd phenom x2 555 be unlocked to 3 cores and oc'd to 3.6ghz

 

[koooowweeee]

run 3d mark vantage and post your scores. i have nearly the same card (xfx 5770) and ive writen loads of score i have from clocking so ill no if your card is being bottlenecked

But you are forgetting the 30fps vs 33fps is the average fps, minimum frame rate is most likely going to be at around like low 20s/high 10s or less.

Does the ram on the 5770s start slowing down due to error correction? Just thinking if your minimums are taking a hit your ram may not be stable.

TPU 5770s review gave 11% increase after OC so you seem in the correct ballpark.

True
Nearly forgot about min FPS

ok heres the 3dmark results before and after the oc

before 850mhz 1200 mem

after 960mhz 1250 mem

you think its worth upping them mem?
