I think your R300 cards will be faster than his R200 cards, in both clock speeds and performance.

Thanks Andreas,
I had no idea what he was using (its not in his post).
And actually, till Mark and Frank get the 3D driver finished, only some things would be faster.

I'm still trying ton digest why so many people are having problems with this (flashing).

Except for 9200 cards, its a relatively easy procedure.

One 9800XT and one 9800PRO 128mb card arrived today.
More scheduled to arrive tomorrow.

> till Mark and Frank get the 3D driver finished, only some things would be faster.

True, I meant to refer to pure 2D operations only.

Sorry for stating the obvious.

Yes, with at least twice the pipelines of other supported Radeons and an over 100MHz GPU speed advantage the R360 card I've been using flies.

And the other R300s are only slightly slower.
Starting with the 9500 that clocks the same as an 8500, but has twice the pipelines.
To the 9700 which operates 50MHz faster still.

This is going to give us a serious boost in graphic performance.
And they're fairly cheap.

Two 9800XTs are here right now ready to undergo conversion (as are a 128mb 9700Pro and 9800Pro). One further 9800XT should be here by Saturday along with a 256mb 9800Pro (that AmigaDave, who can't seem to make up his mind, now says he wants). And I've got bids on one more 128mb 9800Pro, one more 256mb 9800Pro, and one 9800XT.
After that, I'm taking a break till October 30th

Hi guys,
Will this cards be Pegasos II compatible or only PowerMac?
Thanks

@Jim

Thanks for the input. I already tried out the full 128K rom for the 9800xt, still corrupted graphics. Only one that works is the 9800 Pro bios thats been hacked for 256MB. Yea the clock speeds are backed off, but I will leave them to that so maybe it runs a bit cooler. :) My other two 9800 PROs work great with the same bios this XT is using.

I am more than prepared for the new drivers once they are released. :)

That's cool. I'm worried that using the 9800XT bios could be problematic anyway as I'm not sure the MorphOS drivers handle fan speed control. And you lose DVI output anyway.
I'm currently re-fitting my own 980XT and the two others I've bought with third party fans.

BTW - Welcome to the club. I expect this card to grow to rival the R200s in popularity (if not exceed them).

Wow. Andreas answered this for me once and I can't recall the details.

I do know that Radeon 9700 and 9800Pro cards are keyed universally (which mean they'll work in 8, 4, or 2X AGP slots). Looking at a 9800XT, it looks like its a 4x/8x connector.

But..I don't remember if that's still OK with a Peg, but I believe so since its really a matter of the voltage used (not the transfer speed).

Yo, Andreas?
(Hope so because I'm trying to acquire one).

Yo, Jim, that's right :-)

Isn't that frightening folks?
One day I hope to meet this man in person just to tell him how impressive I find his ability to index information.

Good. So we can use 9800XT cards with a Peg (and maybe one day an R400?).

> So we can use 9800XT cards with a Peg

Yes.

Not likely:

Old quote, Andreas.
Frank's had a G4 modified R400 for several months now (I sent him one).
I should have sent him two by now...

BUT...There are some issues running these cards in G4s, and that quote is still for the most part true.
I've had G4 modified R400s running now for about a year, but not all cards that work correctly in G5s will work in G4s (and I don't know why). And Frank still needs to figure out the fan speed controller.

Also, I think he said that since Mark sold his G5 he has nothing to run an R400 in.

Plus, well, lets face it, not everything that gets explored gets followed up on.

I'm perfectly thrilled to have R360 support about to be completed.

And even though it intrigues me, I'm not sure with the complications that its a good idea for most mainstream MorphOS users.


Finally, Frank and Mark have never committed to supporting the R400s (or G5s for that matter).

"For Pegasos2 or Efika (space/mechanical issues unconsidered) it's completely out of the picture."

So you say this statement is not valid anymore?

I guess you are talking about PowerMacs here, whereas I am referring to what you were talking about in the part I quoted from you and replied to, which is the Pegasos (II).

>space/mechanical issues

Damn you're quick.
I was about to get back to modify that.
The Efika is out of the question, but then an R300 wouldn't fit in there either.
But there are R400 cards that are no larger then an R300, so on this one I'd differ. The Peg is probably doable.

However, this is still a dodgy issue. R400s are a bitch to get working in a G4 (but when you do they are SWEET).

Edit - You know, now that I think about it an R400 in a PegII might be easier then a G$ Mac (no bios issues).

Well, pega-1 wrote "space/mechanical issues *unconsidered*". Wouldn't that mean that it wouldn't work with the Pegasos II (for whatever reason) even if there were *no* space/mechanical issues? Or am I misunderstanding?

Good question.
I'm having trouble parsing that as well.
Maybe it would be easier just to ask him.

Then again, I hate bugging Frank over an issue that doesn't pertain to something they've committed to support (read that as I've already been a big enough pain in the ass about the R400s already). ;)

@Jim

The first 9800 Pro I got had an aftermarket cooler and passive heatsinks for the memory chips. I had to remove the 4th memory ram stick since it got in the way and for it to close, You have to hack out a chunk of the 5 1/4 metal case that houses the CD drive, so move the CD drive one slot down and then remove as much as you need...

I will borrow a dremel sometime and do it, but for now I am using the 9800XT, so it closed up fine without hacking it just yet. :)

Hello,

have a look at this: http://amigaga.chez-alice.fr/ng/bidouilles/video/cg_comparatif.htm
In "Compatibilité matérielle" column, you can see where you can plug cards.

@ Doffo

Yes, I've had clearance issues with both my Quicksilver and my MDD.
The stock XT cooler does have the advantage of being narrow.
I have a Zalman and one other third party cooler I'm going to check out to see how they work in those two models of Pmac.

Edit: Basically, on Pmacs with the AGP port on the right side, the cooler covers one additional PCI slot.

[ Edited by Jim 26.10.2012 - 03:31 ]

One 9800XT and one 9800Pro (128mb) card left.
So far, the coolest looking one is the 9800XT with a Zalman cooler set up for Cool_amigaN.

It's mine, it's mine, it's all mine! xD

As far as I know, there is no R4xx based AGP card that matches the electrical specifications of the AGP connector provided by Pegasos2.
R3xx cards like Radeon9800Pro or Radeon9500 should work just fine (I'm not sure about 9800XT) but Radeon96xx already uses a lower signal voltage which isn't supported by the AGP connector.
There might be some PCI R4xx based cards which probably work in the PCI slots.

Thanks Frank,
I had my doubts when I noticed that the Pro had a universal AGP connector and the XT had a 4X/8X connector.
And I guess there just so far that we can upgrade the Pegs. Still, a 9800Pro is no slouch and will provide them with quite a boost.

BTW - As far as I can tell, most (if not all) 256mb 9800Pro cards are R360 based.

Um, probably a little late to ask this, but will R360 based cards work in older Powermacs?
I only have a Quicksilver and an MDD so I can't test this out.

Edit - I did a little research. The R360 based cards are only going to work in Digital Audio and newer Powermacs.
Older Powermacs will have to settle for a 9800Pro.
