MY ATI RADEON PAGE


ATI Radeon 32MB DDR



This is a 32MB radeon DDR like I have.This card is now called a Radeon 7000. This 32MB OEM version runs at a clock speed of 166MHZ Core and 166Mhz Memory. Which is DDR memory,(Double Data Rate),so It would be an "effective" clock speed of 332MHZ. I believe the DDR Retail versions of these cards comes with a core/memory clock speed of 183MHZ which is 366Mhz DDR.

OverClocking The Radeon

(Of Course)

Personnally I never had much luck overclocking my Radeon but I think it was due to the poor 6ns 166Mhz DDR ram that is on it. The core and DDR are to be run SYNCRONOUS,(The Same MHZ),on this card because of the design of its memory controller. Some people have had these cards running at 183/183Mhz and ABOVE without a hitch. I assume that they had better ram on theirs. I had no luck above 177/177 Mhz although the CORE would run 190Mhz the memory choked out at 178Mhz.

Here I removed the stock heatsink and lapped the core,installed a large heatsink and fan on the core with superglue and thermal grease and eventually I even fabricated and installed RAMSINKS on the thing...still no better luck. Heat dosent seem to be the real trouble with overclocking the Radeon cards,its the DDR Ram. The 5.5ns<166Mhz> and 5ns<183Mhz>, seem to overclock better than the 6ns DDR Ram. A note of caution when buying these cards if you want a good overclock..make SURE the card is RETAIL and NOT OEM! All in all its a pretty cool card and graphic quality is AMAZNG. It is the ONLY card previous to the GeForce3 and Kyro3 Cards to Support DirectX 8. It also supports 2X and 4X FSAA but 2X is all I ever got to work at/above 800x600 res. I reccomend just using a higher resolution,(1280x1024), instead of FSAA. But you will need to have a Pentium III-933Mhz or better processor and 256MB of system Dram or more to actually enjoy this higher resoulution. The Radeons,although no where NEAR as bad as the Rage 128's, the 7000's are still some what processor dependant.

RADEON 7500 OVERCLOCKING


I just recently upgraded to a 64MB 7500,OEM again,running at 230/183Mhz. It seems that because its not made by ATI directly but by its partner,Saphire Technologies,no application would overclock it. SO.. After a few months of what seemed like a HOPELESS quest.. I finally got a tweaker to work..I Emailed Sapphire Tech and after explaining my plight..the sent me Ati's actuall IN HOUSE TWEAKER..amazing eh?! Well it was all good from there cause a dood over at Rage3D forums directed me in the correct path of making these Sapphire cards go.. so.. I want to share it with EVERYBODY!!

First you need to grab The Radeon Bios Editor and The Radeon Bios Flasher and if you have the Sapphire OEM 7500 get this Retail 7500 Bios to Flash the card with. Below are the exact instructions on how to do this.. so read..and have fun.

BOOT INTO DOS MODE,Go into your folder that you dumped flashrom.exe and flashrom.rom into run this command...

flashrom -s 0 my_bios.rom

That command gives you the bios that you have on your card right now, and saves it as my_bios.rom in the same directory as the program. Now go back to windows open up my_bios.rom with radedit and change your clock speeds If your gonna use your cards origonal sapphire bios and not the retail bios here that you can download. Also make sure you know how high your card will run stable!!The retail bios sets your core to 290Mhz and the mem to 230mhz.(ALL CARDS SHOULD RUN AT THIS SPEED) Now Reboot into dos again....from a boot disk or whatever and run this line

flashrom -p 0 my_bios.rom r

...yes that is a zero,and that should flash your new bios to the card. What is cool is you can edit/change the bioses and flash the card as much as needed to make it 100% right. You may want to keep a PCI vid card around in the unlikely event that the power goes out whie you are flashing your Radeon.. that way you can put the PCI card in and boot to DOS and reflash the Radeon. Now you will never have to install an overclocker again!!
