Resolution option disappeared (B&W + Radeon 7000)

[Emehr]

I have a 22" 1680x1050 LCD monitor hooked up to my B&W G3 that has been chugging along fine at that resolution for quite a while now. All of a sudden, after a fresh reboot (I don't keep it running 24/7) there are no options for 1680xanything in my Monitors control panel (or control strip). And the frequencies next to many of the available resolutions seem a lot higher than I remember (like 120 - 200Hz!). What is going on here? I didn't install anything and I didn't change any extensions around.

I tried the "all resolutions" trick (holding control while clicking on the Monitors control strip). Nada.

I booted from a CD that I put together a while back that has 9.2.2 + the ATI drivers that make this combo work. No dice. (worrisome)

I tried resetting the CUDA button and zapping the PRAM. No dice.

The monitor is not at fault. I attached it to my PowerBook G4 and it went straight to the 1680x1050 resolution.

I removed the Radeon 7000 card and reseated it. That didn't do anything. (It's in the second slot, BTW. I keep the original Rage 128 in the first slot.).

Now, after the CUDA/PRAM tricks, the scrolling and redraw on Finder windows is sloooow. [edit: fixed that, disabled an extension I shouldn't have.]

Thanks in advance for any ideas. This is my animation workhorse. If I have to go back to my 17" CRT I shall weep.

Try plugging the display into the old ati rage card, start it up as normal. Then shut it down and swap back to your newer video card.

You do know that in the B&W G3 and PCI GFX G4 the shorter slot is 66MHz 32bit and the long ones are 33MHz 64bit.. right?That shorter one is faster and unless I am mistaken the Radeon 7000 is supposed to support 66MHz.

I don't know why that worked but it did! I tried just about everything and never thought to do that. Thanks! I owe you one!

Thanks I actually forgot about that. I did try the Radeon in the first slot but my Mac crashes at some point during the booting sequence. Not quite sure why. Things are more stable when it's in the second slot.

I think when swapping cards like that, it erases the settings from the two cards.

Glad it worked! |)

Just to verify, the two slot types actually have the exact same throughput.

BUT.....

The shorter 32-bit, 66 MHz slot is on its own bus, while all three 64-bit 33 MHz slots share a single PCI bus.

And while the slots are backwards compatible, obviously, as the 64-bit slots are only 33 MHz, the video card would run at 32-bit, 33 MHz. So yes, in relation to the video card, the shorter one is faster. But if you're comparing a 32-bit 66 MHz card to a single 64-bit 33 MHz card, the total throughput of each would be the same.

(And, if the physical slot doesn't cause a problem, you would get the same throughput for a 64-bit 66 MHz (or higher PCI-X) card in either slot.

To end though, yes. Apple designated the 32-bit 66 MHz slot for video cards, so any Apple PCI video card should support 32-bit 66 MHz operation, and therefore would be fastest on that slot.

Yes, I could have gone into more detail, but I was just meaning for his use and 98% of the PCI cards most people will use. If someone is buying/working with a 64bit card then they probably(hopefully) know what they need to know.
