ATI Tool 8800 GTS

[AngelicPenguin]

I was following this guide to overclocking my 8800 GTS

And have a question about the memory setting. I've got it up to 1120 and have yet to see any artifacts. Am I doing something wrong? That post listed 1060 as the max they got, so I'm beginning to wonder if I'm just doing it wrong.

Overclocks will vary from card to card, and manufacturer to manufacturer. If you aren't seeing artifacts, then keep bumping it up until you do, then back it down a little from there.

I'm at 1170...I feel like I must be doing something wrong

How long do you leave the artifact scanner on any given level?

Oh and howdy neighbor (Round Rock)

You will see artifacts very quickly, in fact ATI tool sees artifacts well before you will see them in game so some artifacts are ok. Just keep bumping it up until the yellow specs start showing up.

It's at 1665...

I don't get it, it listed the default at 792...no way you can double the clock right

I run nTune to check the bus speed and it says "GPU memory: 1665.000 Mhz"

:S

Glitch in the drivers, if you're running a dual monitor setup you cannot overclock the memory. I had mine up to like 6000mhz and no artifacts =P

 

[AngelicPenguin]

Can you disable the second monitor and overclock it to find the settings? Or if you plug the second monitor in it won't work anyway...

And thanks!

Not entirely sure, I never tested it to be honest. =/

LOL, fair enough, shows how much I know about the 88's...

Sure that isn't 1600 mhz effective? Try using everest to see what the clocks are.

I like your avatar pic btw, super cute.

haha, well that helps me a bunch actually. I have been trying to figure out why the mem wasn't clocking up too!

 

[AngelicPenguin]

Disabling the second monitor in windows allowed me to overclock the memory. I could see it was actually working this time because the temperature of my card began to rise in ATITool (rather than staying around 70 degrees C). I suppose I'll need to get some sort of VGA cooler or something because it hit about 87 degrees C. It was around 1065 when it started having artifacts, but the computer also hard locked at 1045. Once that happened, I just shut it off for the night

So during "scan for artifacts", would that be considered "under load" for the card? Is 87 degrees too hot?

Well I'm pretty sure now that the second monitor thing was brought to light, that I in fact, was doing nothing. Good use of time

Yeah, "scan for artifacts" would be considered under load, especially at those temps.

Actually, I'm in Round Rock, but I put Austin cause I figure it's all the same these days.

I find that the ATI scan heats up my card more than looped 3Dmark and most games. Does a pretty good job on the CPU too...

Success!

If anyone is interested, it clocked to 615/1015. I'm not sure if it could go higher, but I had a hard lock at 618 when running "Find Max Core" and 1015+ started giving artifacts.
