Visiontek ATI HD 4870 512MB DDR5 Memory FPS Problem

[conners]

Hey all new here. I have a Visiontek ATI HD 4870 512MB DDR5 Memory which I used RBE to mainly up the clock hiend settings to 990/1200.and the fan control.

Currently the clocks are 800/1100 from the standard. No matter how I OC this card the FPS always is around 29/30 in 3DMark vantage.

Is this normal or am I doing something wrong?

thanks in advance!

NOt sure if Vantage is a good benchmark to use. Have you tried any other benchmarks to see if overclocking improves anything?

Thanks for the Reply. I have to admit I'm a noob on video card OCing. I have used FurMark @ 1980x1020 bench and the average stays around 13 FPS in it on various oc settings. I seems like it ocs but doesn't any in the fps. What do you recommend for benchmark to use?

Ok tell me something...When I run the benchmark you suggested in DX10 mode I get like 230 +/- fps but alot of little black boxes in the picture. Why do this happen?

Never mind a reboot took care of it...Sorry

Here is a quick approx 10% OC on both clocks using the recommended benchmark program.

750/900 (stock)
Scene 1 137.85
Scene 2 106.61
Scene 3 174.51
Scene 4 109.42

826/991
Scene 1 151.97
Scene 2 113.33
Scene 3 181.49
Scene 4 122.57

Is that about what one should expect?

FWIW there are my final test results.

Devil May Cry 4

OC @ 835/1090 (best I could acheive)
S1 - 154 fps
S2 - 114 fps
S3 - 194 fps
S4 - 121 fps

3DMark Score 11798
AquaMark Score 152,550
FurMark 14411 @ 16 fps Max temp 76 degrees.

Thats about a 11% gain on GPU clock and about a 21% gain on memory clock.

Thanks for all your help pointing me in the right direction in overclocking the video card.

NOw to try it out in real life games as BF3 and Deus EX HR and will let you know the results.

Thats what you should expect on the money, your Q9550 E0 @3.92GHz is no bottleneck free flow goodness, I wouldnt sweat those scores, looks on the money to me.

If anything to nitpick would be 3DMark Score 11798...little low but not much.

In Battlefield 3 (online play)@ 835/1090 I experienced tearing and couldn't even aim. lowered @ random to 820/1030 and play was fine. Haven't had time to see if I could do better but I will.

Again thanks to all involved.
