Using CCC ati overdrive, I tested my new xfx 5770 with 3dmark06 on a xp32 machine with a single monitor.

These are the results in the order that I did them, using an e4400 @ 2.8ghz, default memory 1200mhz.

gpu: 850mhz
3dmark06: 12405

gpu: 875mhz
3dmark06: 12315

gpu: 900mhz
3dmark06: 11969

gpu: 925mhz
3dmark06: 11863

gpu: 960mhz
3dmark06: 11785

gpu: 850mhz
3dmark06: 11527

gpu: 850mhz
3dmark06: 11589

closed chrome
gpu: 850mhz
12204

gpu: 960mhz
12300

My scores went down as I increased the gpu. At first I thought it was ati's new error correction tool that fixes artifacts but decreases performance.

But when I tested it again at 850mhz the score was almost 1k below what it should be.

When I closed google chrome it had 5 futuremark pages open. Could that really make a difference of 700? Also the score should have went back to the default of 12400, not 12200.

Then I just started restarting my comp in between tests. Got no performance gains at all.

Did I get a dud? Does this score fit with my cpu? Is there some handy new tool that ati has invented that's messing with my results?
 
I played bad company 2 and it crashed like 3 times.

I was about to rma the card but it plays l4d2 flawlessly 75fps all maxxed, played cs source np and war3 np.

And since it ran all those 3d mark tests without any artifacting I have to conclude its an ati driver/bc2 problem, which really sucks cause I want to play bc2.

k now im thinking of rmaing it again
crashes few seconds into EA's burnout paradise with lines like this

I've been following your issues the past few days and yes it seems strange. Whats not strange is for 3DMark scores to decline if you continue running the test over and over without reboots. Highest scores usually occur after a fresh boot.
I'd consider the rma myself xfx is good about it. Before you do I'd try maxing her out in terms of an OC. For instance I have yet to see you move the memory off 1200Mhz. Also while 960Mhz is decent on core I wonder if you're hitting the 960 CCC limit? And using something like MSI Afterburner see what you achieve with 1.3v on the core.
A lot of people complain about BC2 issues. But if your games play fine and your only true complaint is scores in 3dmark than maybe you keep her.
Try running some game benchies at both stock and OC'd levels.
 
The graphics card was at stock speeds when testing bc2. It crashed in 3 different ways:
-when I had two monitors running, the game froze and all I could see were coloured lines on both monitors
-as soon as I got into the game the screen was all black except for the hud
-when I started playing all the textures were artifacting

its easy to say rma, but how do you explain then running l4d2 all maxxed perfect at 75fps no crashing/artifacting, running cs:source all maxxed no crashing, and running all those 3d marks no problem.

im not thinking of ocing it atm i just want to know if the card crashing is a driver issue, or if i should rma it

im going to reformat and try it again, i just uninstalled my nvidia drivers from my old 8800gts and installed the catalyst ones

i wish i could install 10.3 drivers but they are win7/vista only and im running xp

So only BC2 has issues? Maybe its just a driver issue with BC2 the way so many of us have Crysis issues on the last level
