Hello everyone.
For past few days i have seen a lot of people asking about how to overclock ATI cards and what to use to do the same.
Well I personally got tired answering every single one so decide to write this article which i think will answer most of your questions.:P
This is gona be big so i have given bold headtopics. You can directly start reading from desired section.

Types of overclocking

Overclocking a Graphic card involves 2 things
1. Overclocking your GPU.
2. Overclocking RAM on the card.

When you overclock the GPU you increase the frequency at which your core is gona work. ANd when you overclock the RAM its the same thing, the frequency at which ram works is changed. Its observed that overclocking the RAM usually helps more than overclocking the GPU. The obvious reason is when you overclock the RAM the bandwidth availabe on the card increases.

Before you overclock

Always keep in mind that any kind of overclocking involves risks. You simply dont get everyting without giving nothing away. If dont without taking proper care you well might end up frying your card.
Officially it does void warranty when you overclock but you can as always work around this problem by taking some simple precausions which i will tell ya along this article :P

Does choosing a perticular card makes difference in overclocking?

Yes its very important to check few things before you buy the card which you intend to overclock. Choose a card with better cooling solution if you dont wana change the cooling solution yourself. But dont spend too much on a card just for cooling solution. you might end up paying less if you do it yourself. (checkout last topic in this article).
Check out the memory chips used on the card. Prefer cards with Samsung or Hynix memory.
There are many versions of card which are very confusing like 9600 non pro, 9600 pro, 06--XT, 9600 pro EZ.
Always check the clock and memory speeds of cards you intend to buy and double check it.
Forums like these are very useful place to get this information..

What you need to overclock ATI card?

You need some guts and following tools.

1. Rivatuner : A nice tool which lets you overclock and also tweak your graphic card. It can be found in download section here at guru3d at www.guru3d.com/files
You can also use 1 more very popular tool called rage tweak which can be found at www.rage3d.com

2. Bios Files : Well some of older cards like 9700 np 9500 had their bios locked so it was not possible to overclock them. But there were people who broke this code and released unlocked bios files.
The whole collection of ATI BIOS and BIOS FLASH UTILITY can be found HERE
Newer cards like 9800XT/Pro, X8XX series dont have their bios locked.
UPDATE : I JUST NOTICED THAT THE SITE ABOVE HAD UPDATED ITS FILES AND HAS REMOVED README FILE FROM THE BIOS FLASH ZIP FILES WHICH USED TO CONTAIN README FILES. SO I AM WRITTING THE BIOS FLASH STEPS FOR YOU. I PERSONALLY USED ATIFLASH AND FOLLOWING METHOD IS NEEDED TO FLASH YOUR BIOS USING ATIFLASH(ALL VERSIONS)
1. MAKE A DOS BOOT DISK. IN WINDOWS XP GO TO MY COMPUTER>RIGHT CLICK THE FDD ICON AND CLICK FORMAT AND CKECK THE BOX "MAKE BOOTABLE DOS DISK"
2. UNZIP THE ATIFLASH ZIP FILE AND COPY ALL FILES IN IT TO YOUR FDD. ALSO COPY THE BIOS FILE TO THE FDD
3.BOOT TO DOS USING THIS FLOPPY
4. FIRST SAVE YOUR ORIGINAL BIOS FILE. IT WILL BE NEEDED IF YOU DECIDE TO REFLASH YOUR ORIGINAL BIOS. TO DO THIS TYPE FOLLOWING AT A:>

atiflash -s 0 backup.bin

or

atiflash -s 0 backup.rom

THIS WILL SAVE YOUR BIOS FILE ON FDD WITH NAME BACKUP.ROM

TO FLASH THE CARD WITH NEW BIOSFILE TYPE

atiflash -p 0 biosname.rom

or

atiflash -p 0 biosname.bin

THE .BIN OR .ROM EXTENSION DEPENDS UPON THE EXTENSION OF FILE YOU DOWNLOADED

remember "0" in all above commands is zero and not O.


How should you overclock your card? and what is safe overclock with your card?

Do not make mistake and directly overclock your card by 50 MHZ. This is common mistake made by many people. Also many people ask what is safe overclock range for my card? There is no perticular answer to this question. Every card is different and has different overclocking potential. Follow the following procedure to get the best overclock with your card with what cooling you have for now.

1. Increase your core and memory speeds by 5 Mhz each atmost at a time.
2. After you overclock run a benchmarking software like 3dmark2001 or 3dmark2003 or software like "rthdribl"( this is my personal choice as this really pushes the card to max but will only run on Dx9 cards) or some graphic intensive game for 5 minutes.
3. If you dont see any screen courruptions, small black triangles, white or black dots and artifacts then it means this speed is ok for you.
4. Again increase your clock and memory speeds by 5 MHz and again run the benchmark or game.
5. Keep doing this until you get system crash or lockdown or artifacts/white-black dots, scren courruption. This is the absolute limit og your card.
6. When you see these symptoms reduce your clock and memory speed by 10 Mhz.
7. Now try just overclocking RAM and not the core again in steps of 5Mhz until you get artifacts or above symptoms.
8. when you get artifacts again reduce the memory speed by 10Mhz and this is your final safest settings.
9. Always run your card atleast 10Mhz slower than the speeds at which you get artifacts.
10. If ram dosent overclock more the you may try same thing with core only keeping RAM speed constant.

Is extra cooling needed if I overclock?

Its not nacessary but recommanded. Have a good airflow in your case. A fan blowing air directly on card always helps.

What about replacement cooling for my card?

If you really want to get 100% from the hardware you just bought you might want to consider alternate cooling solution. ATI stock coolings are not really ment for overclocking.
There are few really good cooling solutions out there.
One of them is Ventec Iceberq 4. While this is good for 9500 pro/non pro, 9600 non pro/pro/xt I wont recommand it on high end cards like 9700 pro or 9800 pro/XT.
FOr these High end cards prefer one of the most popular one Artic cooling VGA SILENCER. you can check it out at Here.
Do remember adding Ramsinks does help on ram overclock. Some good readymade one are populat Tweakmonster Ramsinks or in case of VGA silencer you will need low profile ocz ramsinks

Remember If you attach your ramsinks using epoxy like Artic silver thermal adhasive the joint is permanent and cannot be removed, so when it comes to RMA your card you wont be able to get any warranty benifits. You can use thermal pad which can be taken off but using thermal pad is the worst way to attach ramsinks

You can also buy some readymade kits. here is a very good link for kits like these
http://www.imageevent.com/marginjohn/viperjohn
Now thats what you call some kick @$$ cooling ;)


Never throw away original Heatsink Fan.

You can also cut the AMD HS into small pieces of size of ram chips.

Now to some serious overclocking and cooling
If you have some experience of overclocking and feel confident enough to move one here comes some serious overclocking.

Before I move on to this there is small thing you can do. If your bios support it try increasing AGP voltage ( AGP VDDQ ) This helps to get little bit more overclock out of the card.

If you do feel like you have reached limits of your card and still want to overclock more the watercooling is a way to go. Watercooling increase the possibility of overclock by almost 30% more overclock than air cooling.
Also remember that watercooling also runs card a lot cooler resulting in increase life of your hardware.
You can use watercooling just for your videocard. You will need a good waterblock. And the best one are Maze4GPU waterblock by dangerden which can be found at www.dangerden.com. The other good one is Swiftech.

There are also voltmods you can do but requires knowledge in electronics and some soldering experience.
Search vmod for your card in www.google.com

Also here are LINKS FOR VMODS That i found.

I have a Sapphire 9800pro. Sunny fashioned a good old P3 HSF and transistor heatsinks for the RAMs. The ramsinks are attached using a lot of thermal paste. Does a pretty good job cooling the core when compared to the stock sink. Will be flashing the bios to the XT one since mine is an R360 :D

I like ATI Tool the best.

You can get it at www.guru3d.com

It has everything inbuilt. My x800 xl is oc'ed at 425 / 505 right now.
Im gonna oc further as i just bought some additional cooling for my PC.
 
any picture guide links for how to remove your stock hsf and then apply AS5 on the card for better cooling ?

I am looking for a guide for my x1800xt but any reference guide will do. thanks.
 
X1900XT/X Overclocking

NOTE:Following instructions should also work for x1800 series
As most of you guys who own X19k series card already know, its not the easiest card to overclock beyond the limit of ATI CCC.
In ATI CCC there is a limit for overclocking which is set to 690/1600 for core and memore resp.
But may cards will overclock beyond this limit with small bump in the voltages.

There are 2 tools available for this.
1. Overclocker
2. ATI Tool
1.OVERCLOCKER
Overclocker is preety simple tool.
It has simple GUI and ability to control fan speed, core/memory clock and core/memory voltages.

Download this tool here : Overclocker for X1000 series
Please note that all overclocking should be done in the 3D mode.
overclocker1cg.jpg


You will need to increase the core voltage to overclock in 3d.
For X1900XT the default 3D voltage is 1.425v. As these cards work in 2d and 3d speeds, the 2d and 3d core voltage is different.
So before overclocking make sure your core voltage is set to minimum of 1.425v. Some cards do work at lower voltages but not all. And your PC will freeze of the card cant overclock to the set speed at lower than default voltage.

There is small bug in this program. As you can see there are up and down pointers to increase and decrease clock speed. These dont work. If you try to increase clock speed over default 3d speed. it reverts to default 2d speed of 500 mhz. Insted just type the clock speeds you want in the box and click on set clock.
Test for artifacts and as usual increase clock speeds in small steps.
Once you hit the wall try increasing core voltage by a notch and overclocking more.
Make sure you manually increase fan speed as bumping voltages causes lot more heat. Personally i set fan speed close to 80% of max while benchmarking.

2. ATI TOOL

This tool is lot more complicated but also has more features and you can control multiple voltages with this tool.
Only 0.25 beta 14 is compatiable with x19k series overclocking so only use this version to overclock the cards.
It can be found here : ATI TOOL 0.25 BETA 14

Overclocking with this tool only works when ati service "ati2evxx.exe" is not working.
Dont worry, the tool will show you a message at start warning you about this and it will also kill the services for you.
atitoolmessage0xv.jpg


Then you will be greated to the main window.
atitoolmain0ec.jpg


Similar to overclocker you will first need to set the 3d voltages. For this click on settings and select "voltage control" from drop down box.
atitoolvoltage5ac.jpg


Here you will see 4 voltages.
Make sure you change vgpu to 1.425v or more while overclocking.
MVDDQ and VDDCI are two additional voltages.
In general i have observed that MVDDQ needs to be set same as MVDDC and
VDDCI same or slightly more than VGPU.
The only way you are gona get perfect settings for your overclock is by trial and error.
But make sure to keep an eye on temperatures while increasing the voltages.
If you plan to overclock 24x7 with stock cooler i wont suggest more than 1.5v on VGPU and 2.15V for memory. For short benchmarking its ok to go higher but dont push too much voltage for getting slightly better overclock.

Also there is fan speed control page with more comprehensive settings in ati tool. Here is a snapshot of the same. I dont overclock my card 24x7 so i prefer using high fan speed for benchmarking.
atitooltemp9do.jpg


If you have time and patience you can use ATI tool's max memory and core speed finding feature.

Note : None of these tools work with Catalyst 6.4 so only use CCC if you are using Cat 6.4 or better use 6.3 or newer 6.5 version.

I had written instructions for x1k series cards a while ago but completely forgot to post the same. SOrry for the delay. found this while searching old backup DVD disks..

Can any mod please integrate the above post with 1st one or move it to the 2nd post position in this thread???

As usual please point out any mistakes / misinformation / dead links.

very nice..repped you....may nt count coz im still not green....anyways...

i dont see the point in overclocking a card like X1900XT. I mean seriously u gotta be nuts to do smth like that unless u r a testing freak...
 
Err funky I thought the default vcore is 1.425 not 1.475. Atleast mine runs perfectly stable at 1.425.
 
Yeah its 1.425, my bad.

at stock mine even runs at 1.350v.

@vij

Well personally i dont oc it during gaming. Its just for plain benchmarking. nothing else. Some people keep their cards oced from ccc due to the monitors they have supporting insane resolutions and specially for games like Oblivion.
 
I ve got a Gigabyte Ati Radeon 9200SE card.. are there any tweaks or OC sws available for it? Also is there any specific driver for it? Do i require any cooling equip if i wanna OC it?

m sry kinda noob ..plz bare.. :ashamed:
