Ok I ran 3dMark 1 week ago, I scored ok @ 12,405

Now when I OC my 4870 card my score went down significantly?
Its now scored at 7,563!!!

I wouldve thought it would of have went higher!

I have my card at: Memory clock- 1200
GPU clock - 818.20

I guess my question is...did i do something wrong? I also tweaked the fan, but i dont think thats the problem

Well I have an AMD quad 2.2
8gb DDR2 PC6400@800 MHz
ATI HD4870 512mb
x64 XP pro

should be sufficient for a good score! shouldnt it be? at least over 13,000 to 15,000.
I just going by other peoples score too you know.
Some have older cards, only dual PCUs 2 gb memory and scoring over 15,000 iv seen.

So im confused lol
 
x64 bit utilizes alot of it for my graphic design in AE (Adobe After Effects)....mostly rendering... plus it was cheap!!!!

Prolly wont use most of the ram but ill have for awhile when i will need ?!!
 
Well first, undo your overclock and see if your score goes back up. If it does then that means something is going wrong at that higher clock speed. I haven't read into the specifications of the newer ATi cards but it is possible that it has a safety feature that would underclock it upon reaching a certain temperature. I recommend doing an artifact test (easiest way to heat up your GPU) while watching your temps, if it steadily climbs and then the temp drops, that means there is some sort of safety switch that kicks it to a lower speed. Also, if you are going to overclock with stock cooling, I often just force the fan to run at %100, it keeps the card cooler and generally helps reduce artifacting.
 
hmmm

well i went to default settings, it still didnt go up much...8280 now, only like 600 points! grrr lol

all i know is that the first time doing the test it was 11,000 i think.

oh and the temp still the same @ 74-82 average

oh just noticed your link for the artifact test..ill do that now and see what happens.

Do you by chance have a link for this test Gamerman4, and apparently it wont work with x64 OS's, juts read a thread on it.
I infact have x64 bit os

Well if you uploaded you results to the 3Dmark thing, try seeing if anything was different when your score was at 11,000 in comparison to what it is now.

Also, maybe when you ran it before, you accidentally lowered the resolution setting or something of the sort. Also, make sure nothing is forcing Anti-Aliasing or any other setting that might effect your framerate. There are many applications that can make the default settings for your graphics card force AntiAliasing and Anisotropic filtering and such. Make sure all of your graphic card tools are set to defaults (usually defaults are set to "Program setting" or a similar name.
 
If you are using an LCD monitor, refresh rates do not matter, LCDs have their own refresh rates measured in milliseconds. Setting the refresh rate to 60 for LCDs is pretty much what I do.
