    ATI 9000 Pro Overclocking Question

    I have an ATI Radeon 9000 Pro Card I would like to overclock, but being a bit leery of causing damage I need some input from somebody familiar with overclocking.

    I have the Rage 3D Tweak installed and it reads 274.50 in both Memory and Core clocks at initial install.

    Now then how far should I go up the ladder for optimum overclocking and not create a possible burnout of my card or whatever?

    My other 'puter specs are:

    Gigabyte GA-7VRXP
    AMD Athlon 1600+
    512 DDR 2700 Ram
    40Gig Maxtor 7200 RPM HDD
    Creative Live 5.1
    Sony CD/RW
    Win XP PRO SP-1

    Thanks for any and all help.

    I just upgraded my ATI 7500 to a 9000 Pro
    I have yet to overclock the 9000 Pro. I'm gonna wait till my new system arrives...

    But I did overclock my 7500. I was using a program called Powerstrip (works for most ATI videocards). My 7500 'stock' was 175 Mhz Core and 200Mhz Memory.

    I had it running at 230 Core and 250 Memory for a few days. It never froze but gave me artifacts (Video glitches) when playing 3d type games (Simcity 4 and NHL 2003)

    I ran it at 200 core and 220 Memory for the most part, untill I sold it.

    I think 230Mhz (65Mhz was a bit much)
    If your a gambler, like be just up the overclock and try it out. Keep goin till the artifacts are unberable! (Note: it will probably shorten the life of your card though!)

    I'll try to update the post once I get my new system and I can overclock my 9000 pro.

    175mhz core on a radeon 7500? you sure? sounds more like you had a 7200 or orginal Radeon 64mb.. whatever doesn't really matter only major difference between the 2 is the core speed.. ~175 vs. 290 (default, except for 7500 All-in-Wonder, it's default is only 258). and since the 7500 is newer it usually has faster RAM too.. ~175-200 vs 200-250 (default)

    anyways as for overclocking the 9000pro.. you can't "burn" it out by just overclocking it. that requires voltage modding.. which you're not doing. i'd say somewhere around 290 for both core and RAM would be good.. 300 if you're good.. higher then that and you're one lucky son of a gun .

    you'll know you've hit the cards limit when it starts locking up on you, or creating weird artifacts or both. when that happens back off a few mhz and test it again.

    typically ATi's (or whoevers) heatsink and fan is good enough.. the 9000's run pretty cool anyways.. but having extra case fans to get the air moving in your case is always good, for both your video card, CPU and all other parts.

    yes overclocking "can" shorten the lifespan of your hardware.. but, 8, 4 or even 2 years is long enough for most parts you'll own.

    have fun

    There were a few 7500"LE" cards from 3rd party manufacturers clocked super slow at 175/230MHz, etc. The Radeon64DDR was clocked at 166/166, 183/183, and 198/198, depending on the card. Actually the "7200" might be the name for the one at 166/166, but I'm not sure. They aren't the same card as the 7500 though. The 7500 has a better memory controller (more efficient architecture), and it is based on a different process technology from the Radeon7200 and Radeon64DDR. The Radeon64DDR VIVO SE, however, clocked at 198/198, was based on the same process technology as the 7500 because many of them were able to hit 300+ (mine was able to do 315MHz easy on default voltage/cooling and that was the limits of the OC software without flashing again), but it still had the 7200's memory controller. I think it was .18u vs. .15u technology, but I never really found that out for sure. The R64DDR VIVO SE also had 5ns RAM vs. the R64DDR VIVO's 5.5ns..

    Sorry, I just feel special that I know most of that because I researched it quite a bit when I had my old Radeon64DDR VIVO SE (worked on some vmods for it, etc.), so I figured I'd use the knowledge when I can

    As for overclocking the 9000 Pro. I think some of them had clock locks on them to prevent overclocking. May need a hacked BIOS unless r3dtweak fixed that. It might have only been on the 9000non-pro anyways, I can't remember. Anyways, when you begin to reach the limits of the memory, you will start seeing visual artifacts on the screen, sometimes called ripping or dropped polygons, etc. You'll know them when you see them. As for the core...if you get too high, the computer will normally lock when playing a game or something. If this happens, just drop the core speed a few MHz (2-3 or so) and then it should be fine. If it does it again, drop it a few more MHz.

    hmm.. i did not think that those RadeonSE (the 198/198) were also done on a .15, same as the 7500's .. as opposed to the .18 that all previous Radeons were made on.. i always thought that since they came out much later after the introduction of the original Radeon (R100) that they were simply "higher yield" chips on .18.. which is why there were so few of them. but if you say you got your's up to +300mhz then there's no hell in way is was .18 .. that's pretty sweet though .

    now that you mention it i do recall a lot of 7500LE's that came out.. they were pretty bad.. but were definately ATi's new dirt cheap card.

    yes the 7200 was basically the Radeon given 64mb SDRAM (or 32mb). clocked at 166/166 typically.

    you're also right about the better memory controller on the 7500's.. i think it was the same one as the 8500's.. so there were other advantages to the 7500 core then just the die shrink and clock increase.

    oh these old memories are great to bring back .. makes my feel all tingly inside .. that and it makes it seem like my 7500 All-in-Wonder isn't all that bad .. but in reality it is .. i gotta upgrade soon.
