[Help!] With Overclocking 8500GT

[trihedral]

Well my computer now is in a Antec Nine hundred with 5 fans that brought my GPU Down from 80C to 35C.

My Graphic card came as a 500Mhz Core Bus and 333Mhz Memory Bus. So far i Overclocked it from 500Mhz to 555Mhz and 333Mhz to 520Mhz with no problems. I've been scanning for Artifacts with ATI Tools and it hasn't found any and im getting way faster FPS than usual. My Graphic card currently is 40C and stable. Could i be able to crank it up more?

 

[Evilonigiri]

Yes you can, until your pc crashes or freezes during games.

You can have a little artifact in ATI tools, it will usually never show in games.

 

[trihedral]

Well Evilonigiri im getting no artifacts at all. What do you recommend me to do right now?

OC away! In increments of 10MHz if you want to be cautious.

 

[trihedral]

All right thanks, so is there a hight i should be scared to go? like the max possible to go is 1000Mhz which i dont think i can reach ....

Oh yeah, i also wanted to ask if i can overclock the Core and Memory at the same time, or Memory First?

Do one or the other first.

And before that, is the Core clock and Shader clock synced or not?

 

[trihedral]

I dont know what a synced is. So far this is what i did. Inject Coolbits in and opened my NVIDIA Control Panel and went to PerFormance. Dotted on Custom Clock Frequencies and just adjusting it up and up. Also watching if it has problems with 3DMark01SE and 3DMark06. Frames has been getting a 30% increase or more. Temperature is 39-40C and stable(checked it with NVIDIA Monitor).

But, what is the Synced Shader clock?

 

[Evilonigiri]

First download Rivatuner.

Then follow these steps:

What does Syncing it do? btw im 560 Mhz Core and 540 Mhz Memory now with no issues. Sec. downloading RivaTuner.

I'm gonna help you maximize all the clock speeds, assuming temp isn't a problem.

I should have said link instead of synced. My bad.

When you increase the coreclock, the shader clock increases proportionally with the coreclock. Usually when you hit the "max" core clock speed, it's the shader clock's fault. So by unlinking it, you can OC them independently from each other, allowing you to go higher.

 

[trihedral]

Oh i get it, its like the Core clock can go more, but the Shader can't so you divide them into 2 sections and max each one out alone. Correct?


Also you told me on my old thread that my computer and graphic card was basicly too hot to overclock so i begged my dad to buy me a Nine Hundred Case on sell at COMPUSA. Haha, very appreciate the help.

 

[trihedral]

I have an issue with Rivatuner right now, As it got done loading and updating, it comes out a message saying Unsupported Driver Detected.

Warning! RivaTuner has not been tested with the currently installed display driver.
It is strongly recommended to upgrade RivaTuner to a new Version, otherwise it may not work properly because the driver is not officially supported.

[] Don't show this warming till installing new unsupported Driver

[ OK ]


What do i do now?

Go download the newest drivers from nvidia's website. ^^

Indeed you are correct.
EDIT:You're catching on real fine.

 

[trihedral]

For the Graphic card? i have the lastest Firmware for my Graphic card right now which is the 169.25 for GeForce8500Gt at www.xfxforce.com..

Could there be another problem?

Oh then you're fine. There won't be any issues.

 

[trihedral]

Alright, ive changed the values to 1 but i cant find where the system Tweaks is in order to uncheck link clocks. By the way, so after i do that i can just overclock it on Rivatuner instead of going into NVIDIA Control panel right?

Yes, you'll be able to use Riva tuner to OC your vidcard. Just remember to hit save settings on start up.

So you did every step?

 

[trihedral]

When i click Enable Driver level hardware overclocking, it makes me reboot my computer to detect the frequencies. Do i restart the computer?

Nope, you don't need too.

 

[trihedral]

eww, just restarted my computer for no reason... oh well..

 

[trihedral]

Ahh im so mad, when i overclock on NVIDIA Control panel then restart my computer even though i clicked apply it goes back to 500Mhz and 333Mhz to factory shiped defalt. UGH!

There's not point in being mad. Just bring the clock speeds back up again. Takes 10secs.

 

[trihedral]

Also what the heck Memory clock only goes up to 500Mhz...

 

[Evilonigiri]

There is a way around it. You gotta do all this things, but here's the easy way out:

Use Riva tuner to OC the core and shader.

Use ntune to OC the memory.
