Tools for graffics card overclocking:
RivaTuner
PowerStrip
RadClocker (ATI Only)
ATITool (ATI only)
NVMax (nVidia only)
CoolBits (nVidia only)

RivaTuner and Powerstrip are two of the best.

Learn how to use whichever program you have downloaded and open it. First work on either the core clock or the memory clock. Not both simultaneously. We do this so that when we see artifacts, we know which clock speed is causing them. We will start w/ the core. Increase your core speed by around 10mhz at a time. Then apply your new clock speed. Then look for any artifacts (funky lines, colors, static, etc). There is a slight chance that your system will reboot after increasing your speed. If so, try a lower increase. If everything looks normal, increasing again by 10mhz. Do this until you start seeing artifacts on your screen. Then lower your clock back down the minimum that you can until they go away. Once you think you're close to your max core clock speed that is free from artifacts, test that speed w/ a game. If there are no artifacts there either, your good. If there are artifacts in the game, decrease your speed until there go away. Now you have found your max core clock speed.

Now do the same steps w/ your memory clock speed.

Now that you have found your max speeds, you should have the option to apply those speeds everytime Windows boots. Note that later on you may try a different game and see some artifacts or start to see some after 30min of straight gaming. In this case, you'll have to play around w/ your speeds to figure out whether it's your core or memory clock that's causing the artifacts. Just adjust accordingly.

thanks for the tip DeathONator...
I downloaded the ATITOOL. Push my core speed to 402.xx and the mem stay at default around 337.xx, but when I raise my mem speed to nearly 400.xx, I start seeing lines. I thought the Radeon 9800 Pro mem speed is around 680HMz for the mem. ??? hmm any idea DeathONator? Is there any special setting that I have to do to achieve the speed?

DeathONator: I see that you are using ati radeon 9800 pro as well. r u overclocking it???

For the 9800 Pro, 680mhz is the DDRed speed. So the "actual" clock rating is 340mhz (680mhz x 1/2 of course). I run my watercooled 9800 Pro at 450mhz/350mhz 24/7 for no good reason. I start seeing desktop artifacts at around 396mhz for my memory, but in order for there to not be any artifacts while gaming, I must run it below 366mhz I think it is.

I also use these BGA RamSinks on both sides of each memory chip.

I use ATITOOL and got mine up to 461 for the core, and 369 for the mem. can't go higher than that. SUCK! May be i'll go and grab the eVGA Geforce 5700 128MB DDR2 Ultra and test it out.

Hey DeathONator, it says that the ATI Radeon Pro 9800 mem speed is at 680, why can't I go up to that speed? I remember you said something about 680 x 1/2. How come? Does that mean we've been ripped? LOL

DeathONator

The 9800 Pro has DDR memory. The DDR memory really runs at 340mhz stock. Sometimes you will see it stated as 680mhz or someone will say they overclocked their memory to say 700mhz. They are quoting the "effective" memory speed. You see, double data rate (DDR) memory sends data at double the rate of regular SDRAM. So to make sure people know it's almost twice as fast, they double the actual speed to reflect how it performs compared to NON-DDR memory. The same thing is done for PC RAM. It's called 400mhz DDR memory, but really runs at 200mhz and sends almost twice the data per megahert.

LOL,
you're right, what's up with my brain lately??? DDR, totally didn't think of the meaning of DDR. LOL.

THANKS for reminding me. I think I have to go back to school.

dont forget coolbits for NV...if its still around

DeathONator

I saw coolbit but couldn't find a download. Lol, I guess it comes w/ the detonator drivers and you just have to enable it?

Your right DeathONator it does just need to be 'Enabled' There are two ways to do it, the first being easy the second beng harder, I've only listed the second incase something happens to the files i've uploaded to my webserver, if you'd liek to mirror it somehwere go ahead.

Firstly the Easy way to get Coolbits is to download this small registry value file

http://blair.impulseanime.net/other/CoolBits.reg (100 bytes)
you might have to RightClick and Save Target As (IE) or Save Link To Disk (FireFox http://mozilla.org)

and run it once downloaded click yes and it's done, easy hey

Secondly the Hard way, do this method if you have nothing better to do (Something better do is Play UT2004 or FarCry ) or if the link above fails.

Now what you have to do is open regedit ('Start > Run', then type regedit, then click 'OK') now you have to navigate to:

'HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\NVTweak'

now you must add a DWORD Value, do this by Clicking 'Edit > New > DWORD Value'

now you must call it Coolbits, finally just right-click on the new DWORD Value and set it's 'Hexadecimal' value to 3.

All Done Read on to find out where to O/C your graphics Card.

On your Video Cards Advanced settings (Right Click on the desktop the click Properties, from there Click the settings tab now the Advanced Button, Now click the Tab with your Graphics Cards name on it), there will be a new Page listed called "Clock Frequencies". On that page you can hit the Manual Clock settings Radio Button and start overclocking in the manner DeathONator has stated.

On my Nvidia Geforce 4 TI 4800SE (Stock of 275/550) I O/C to 310/670 easily with no problems, I've never gone higher coz I'm well Afraid of Killing my card (hehe I got Zalman Heatpipe Cooler with Optional Fan it's Kicks But)

Anyway I think that's it if you have any questions or need some help just ask me! :P

Out, Blair

Note: This can only be used with NVidia Cards and i think you have to have Nvidia Detonator or ForceWare dirvers v20.00 + I don't think anyone has anything less than v40.00 or so.

Thanks for the info! I linked to a guide on how to do the 2nd method for coolbits in my first post. I don't think that method is that hard at all . But it's nice to have both methods right in this thread.
