Aticcelerator now Graphiccelerator w/Nvidia support

Turns out my 4mx (rev 1091) isn't supported - that's an ADC/VGA with 64mb on TSOPs .. odd but cool

You should use the NvFlash utility to dump the ROM and mail it to Thomas. He worked out GF4s. I did the GF3 & FX5200.

Could actually be helpful, we are trying to support ALL Mac video cards.

I have an ADC/VGA geforce4mx.... would it be helpful if you had my rom? Just post a link with how to do what, and I'll do so.

Actually, your cad should be supported.

Best thing you could do is try out.

Follow link above and run the Flash util to dump ROM. Then see if "Graphiccelerator" can mod the speeds.

Dang. My Geforce4Mx's rom is 1088.

Does that mean it won't work? Or should I just try it to see if it works?

Anyone with an Nvidia card should first make sure they have latest ROM.

Apple released an updater last year:

http://www.apple.com/support/downlo...odeflasher.html

Run that and see what ROM you end up with.

Whoops I've never seen that before hah.. Thanks

Thanks. That updated my card to rev 1100, so now it worked. So far I've clocked it to 280mhz from 270, and memory up to 220mhz from 200.

Not sure how far you can go with these... but yeah, neat! That link should be in the readme though.

When I choose to dump the ROM I can't find the nvcard.rom anywhere on the disc. I have the 5200 Ultra in the PowerBook 12".

NExt time try reading the readme:

"Please note that on-motherboard graphics cards (iMacs, eMacs, PowerBooks, iBooks) are not supported by the dumper tools."

Ah, readme files! Can't remember the last time I read one of them!

I've gotten my geforce4MX up to 290mhz with the memory to 225mhz, up from 270/200 with no ill effects thus far. Once I get another card I'll crank this thing up to see how high it can go.

Any news on the Geforce2 support? I'm here with a Geforce2 MX 64Mb Twinview card.

I'm now up to 300mhz Core, and memory at 230mhz. Not bad from 270/200. 30mhz up on both. No artifacting yet. I'll keep going.

Edit: Now at 325mhz core, 245mhz memory. That's about a 20% increase in both. This program is cool as hell.

At 315MHz Processor and 216MHz Memory (+20.69% and +20.00% respectively) and it really smooths out Expos� (when I've got 15+ windows) and gaming performance.

What'd you start out at?

Man, this thing just keeps going. Now I'm at 330mhz core, and 250mhz memory. I think these things were pretty underclocked, because I just played COD for 40 minutes with zero artifacting.

LOL, you've got me tempted to pop back in my old card just to see how far I can drive it, though I have this thing about overclocking video cards.

Is there an easy way to go back to the defaults if you do not like the results?

Yep. Just flash the old ram and POOF it's back to stock.

Okay, I downloaded Graphicaccelerator and took a look at the speed of my DP 2.0's 9800XT: Core frequency: 400, Memory Frequency: 360. This appears to be the same speed that the PC cards ship at, so at least I know that it is not underclocked like others have found their 9600XTs to be. Right now I'm pretty hesitant about overclocking. Is there much of a gain in comparison to the risk? Link, you seem to be philosophically opposed to overclocking video cards - did you have a bad experience? As you can see, I am no hax0r. . .

If you're happy with it's current performance, don't bother. But here's what you do:

O/C it a VERY SMALL INCREMENT at a time. Like 5mhz. Then flash the ROM. Then test it, play a 3d game or something that might stress the card a bit. If it still looks fine, and there isn't any artifacting (glitchy looking white pixels along the edges of 3d shapes, usually), it's fine, and you can keep going. Eventually, you're going to reach a point where it's unstable, or it starts artifacting. In either case, clock it back a bit. Since the 9800XT already has a fan, it can probably go quite a bit higher. If you're really after performance, you can look into additional cooling such as one of these things:

Installing one of those will allow you to O/C it much much farther. IF you aren't that adventurous, these can help and they're cheap:

I have some of these installed on my geforce4mx, not sure if they're doing anything because my memory isn't even hot... so... >shrug<

Hrm, speaking of underclocked 9600XTs, mine is showing at 400mhz/310mhz.. weird. I know the retail PC ones run at 500mhz, but the memory part seems to be about right (retail is "600mhz", but apparently 300mhz with DDR) -- which would be just weird.

****. I fried my card. It runs the OS fine, but now whenever I do anything 3d I get red artifcating all over. Weird. It didn't do that when I cranked it up, I played halo for hours. Then, I turn off the computer, move to Milwaukee, and wtf... little red dots all over the place. Oh well. Sianara POS geforce4mx. Maybe I'll crank the thing to see how high it goes before it fries.

Well, apparently 345mhz core and 260mhz memory is too high for the almighty geforce4mx. If I'd have stuck at 330 and 245 I probably would have been fine. Oh well. Die card, die!

weird. Now the card is working fine again. >shrug<
