View Full Version : PowerMac G5 Video Card [Best AGP & PCI]

Okay so, I have a PowerMac G5 with 3 PCIx slots and one AGP slot.
I also have three monitors, one with a ADC connection [but I do have the ADC to DVI Apple adapter][max resolution: 1280x1024], one with a VGA connection [but I do have an VGA to DVI Apple adapter][max resolution: 1024x768], and one with an S-Video connection [if needed I can go buy the S-Video to DVI Apple adapter][max resolution: 1024x768].
The purpose it to run Final Cut Pro on the first two while running a preview of the footage on the third.
Since my bus is practically outdated, I'd like to get the best cards, for PCI, I think that's ATI's Radeon 9200, but for the AGP, I'm not entirely sure...
Everyone was leading me towards the ATI Radeon 9800 [256] and the nVidia 6800, but then I just noticed the ATI Radeon X800 and the nVidia 7800, so now I'm not so sure.
What do you all think?
Any incite would be great.

I would say the nVidia 7800 is the best, but they are very rare and very expensive. New ones go for about 280$ and used ones go for about 240$.

nVidia 6800s are okay, and go for about 150 - 200$.

The ATI Radeon X800 is better option then the 6800, and can find one for about 180-250$.

I would go for either the nVidia 7800 or the ATI X800.


The 7800 is faster, but the X800 has better image quality.

hmm thanks,
what about port wise?
you don't have to research it, just curious if you have any knowledge already...
and the cards are mainly going to be used to final cut and motion, which do you think is more important...im guessing speed, but do you think I should seriously worry about color?

Portwise I am unsure of. But personally I would go with the X800. The 7800s spec wise are the fastest, but driver wise and image quality wise the X800s are better.

i'd have to disagree. The ATI drivers for the x800 havent been updated since 2005 while the every nVidia card's drivers are managed by Apple themselves. I went from a x800 xt (I returned it - the price gauging on them is terrible) to a 6800 gt and I'm glad I did. the X800 is a faster card, but I had problems with the drivers under 10.5 and under day to day usage, its impossible to tell the difference. Except my core animation effects are smoother.

well thanks for providing a different opinion, but, the only place I could find these cards for a reasonable price, was ebay, and I have found the 7800(nVidia) and X800(ATI) for around almost exactly the same price, while I've found the 9800(ATI) and 6800(nVidia) for lower, greenlightracer do you think I should go with the X800(ATI) or 7800(nVidia)?

Between those two, I'd go for the 7800 definitely. Like I said, nvidia driver support seems better, and its also 2 years newer technology over the x800, whose core is really just a modified 9800. You can read about that on the wiki for the x800 (r420 is the core I believe)

When I was looking for cards I ended up going for a 9800 due to financial constraints. It's a nice improvment over the Nvidia 5200 :p

Also I did some reading on the x800 and there were some production issues with them I think, where some users needed replacements. I really wanted that card but was put off by the high price and failure rate (I think it effected a certain batch).

If you have enough funds, probably go for an Nvidia.

Good luck finding your card:)

Apr 21, 2008, 12:31 PM
yeah that's the card I have now!
cool, I think I'll be purchasing the 7800 since I found it for a reasonable price; and the 9200 is in the mail for my third monitor, which right there is a major improvement over my 5200, so I can't wait. Cool, thanks guys.

You may already know this but it bears repeating:

If you have an AGP Mac you cannot use the Apple GeForce 7800GT, because it is a PCIe (PCI Express) card. Your AGP Mac uses PCI-X expansion slots, but these are not compatible with PCIe video cards. You need an AGP card.

It is possible to find certain early PC GeForce 7800-class AGP cards and flash them to the Mac - but they must be cards that use the G70 core GPU, not the G71 that most later cards have. See The Mac Elite (http://www.themacelite.com/forums/viewtopic.php?start=0&t=352) forums (the successor to StrangeDogs) for details.

But if you don't want to mess with flashing a card your best AGP Apple-compatible option would be an Apple Radeon X850XT. It's a bit faster than the X800XT, but harder to find because it was BTO-only. Both X800-class cards offer good performance. The two 6800-class cards are also good (I'm quite happy with my flashed 6800GT), but the Ultra is a double-wide monster of a card.

nVidia made a GeForce 7800 AGP card for Macs.

Unfortunately no, that was a flashed PC card. The strangedogs (now The Mac Elite) video card flashing forum had success flashing a G70-based 7800GS AGP to the Mac using a hacked ROM (can't remember which ROM was used, may have been the 7300 Apple ROM).

You need to find a similar card to the original hacked card or the ROM won't work. Certain GS, GT and GTX cards can be done this way but you need a G70-based card...many(most?) 7800-class cards are G71-based.

The Radeon X850XT is the fastest official video card out there for the AGP Macs.

IF you do a flashed 7800-class card it will be faster than the X850XT, of course. But there was never a "genuine" 7800-class card for AGP Macs.

In terms of performance, you can't go any faster on the AGP Mac than the 7800GTX.

you mean the 7800 GS.

7800 GTX = the PCI express version
7800 GS = The AGP version = the fastest card for AGP G5's at this time.

hope that clears it up. :)

Yes. :o

You can overclock the 7800GS of course, but only the PCIe G5 Macs can take a (flashed) 7800GTX.

(sorry if this is a somewhat old post)

As someone who literally flashed a x800 card for my very same PCI-X G5 (dual 2.7) yesterday there are a couple things to point out:

First off: As far as I know there are NO ROMs for the x800 which enable the DVI ports digitally. VGA and DVI work, but not as a digital output on the DVI. The FireGL 256 (which is a FireGL version of the x800) does work, but they're rare and costly.

Second: The x800 is a very fast card. I had the stock Radeon 9650 installed and got ~30-90 FPS in World of Warcraft and 250-300 in Quake 3. After installing the card WoW does 90-200 and Quake 3 350-400 (or higher, the numbers change rapidly :P)

I used a Sapphire x800 XT. I downloaded the reduced x800 ROM from The Mac Elite Wiki and flashed it using GraphicAccellerator from Leopard (10.5.4) but you must boot while holding shift or the flasher won't work. Flashed it and rebooted. Works perfectly.

One thing you might want to consider is using a Radeon x850 fan on the x800. The x800 has a cooler which just blows air around the case where the larger x850 cooler sucks air over the memory and GPU and exhausts it out the back of the case. I think it might actually make less noise, too.

Please note the x850 cooler blocks the closest PCI-X slot. You must remove the little PCI cover plate from the second slot so the air has a place to go. Also my video card has an s-video port on it and I needed to cut off a small part of the air duct for the x850 cooler to work.

All in all, about 10 minutes to install and flash and 10 minutes to mod and replace the cooler. Made a very noticable difference in speed.

Hi,

my config is:

- Dual G5
- Leopard
- flashed BFG 7800gs with (overclocked version) rom from themacelite

the card works well. My only problem is that the fan is spinning at full speed and it appears not to be controlled by the system.
How can I solve the problem? I tried resetting the PRAM and in OF the command reset-all.

Thx

Maybe this is related to the ROM version altered to avoid the "Temp. Sensor" that creates issues at the boot of the Mac OS X Leopard. Saludos! :D

Thank you for your post, it is very helpful for me.
I have the stock 9600 card in my 2.7Ghz G5, so I am getting about 15-30 fps in WoW. Sadly I get down to 4 fps in Mount Hyjal, so I am looking to upgrade.
Are you able to tell me
1. Is the card you use 256 or 512 Mb?
2. Do I need to update to 10.5 from 10.4 to use teh apple GraphicAccellerator ?

My card is 256 and I am using it for two displays, so it's really 128 per screen.

I did it in 10.5.4. No problems, just make sure you boot holding shift before you flash it.

In WoW I've found the worst thing for your FPS is the draw distance. I have mine almost at the lowest. Turning it up totally kills the frame rate down to like... 10. I suspect it would be 1 FPS in Stormwind. Either way your frame rate seems pretty low. You must have something very GPU hungry turned on.

If you can find the fan/heatsink from an X850 card on its own, I'd recommend getting it too.

Tomorrow (maybe) I will pull out my card and do an article on replacing the fan on the card.

It's MUCH better than the stock X800 fan.

I'd stick it online, but I did it in iWeb and www.forcedperfect.net is still using my PHP-based site which I am too lazy to update. When I finally switch my site over to either iWeb or RapidWeaver (depending on which one sucks less) I'll stick it online.

Thanks for this Forced, I will look into replacing the fan when I can.
I was unable to get the card to work in "safe mode" using 10.4.

I am assuming that I put the new card in, and boot using safe mode and I should see at least some video, that allows me to log in and use the gui based Graphiccelerator to flash the card with the reduced rom file.

I am not sure what difference it will make but I will install 10.5 and give it another go.
Failing this I will try and find a PC with a floppy drive and flash it using a dos tool of some sort.

Before flashing the card you will NOT see any video at all. You must either use a second computer using Remote Desktop, flash it on a PC or use a program which will automatically flash it at startup. Google flashing instructions if you need help.

If the 3850 or 1650 were ever available from Apple in an AGP format they would work. Since they never were, they never will be.

7800 GS has such a loud fan that it sounds as if the hairdryer is still on in the bathroom.
I removed the POS fan, which is not controllable by the AGP G5, at all, and placed a silent, $2 Sunon case fan on top of the heatsink fins.
It had a two-pin power connector, so, rather than mod it to a 3-pin, I stripped the tips and spliced it with the Molex connector(which the 7800 needs) and let the 0.8W come from that. 9 Months, and no problems! This fan keeps my GPU around 50š. DO NOT try to use a low fan or no fan at all. I foolishly experimented with no fan, and just the decent copper heatsink....from 0-100 in 30 mins. Not good.
The case-fan takes up a bit of height, making the use of port 2/4 possible, but iffy, but most will not mind.

PS there are no aftermarket passive heatsinks that fit this card. Put up with the stock fan, or replace it, are the only options.

I don't consider 6800's any good.. 6800's were and are like the SUV's of AGP video cards, bloated and draw too much energy for middling performance; I've gone through 3 of them, one used, the other two brand new; if using them in a stock G4, the G4's power supply blows out and has to be replaced or you have to use fewer RAM chips.

If you use them in a G5 they burn out anyway because regular PC versions have an anemic stock cooler. The 6800's that Apple put in G5s had different, higher power coolers and drew power from that little aux slot intended to provide power for ADC monitors.

X800XTs are good but no one's managed to figure out how to flash a PC version with a ROM that will give you DVI support, you only can have VGA / analog out

Just as an update to my original post about flashing a Radeon X800 with an X850 cooler.

After all this time it still works perfectly. (Yay? :P)

One thing I noticed is the cooler does like to clog up with some cat fur after a few months. So I wipe it off every 3-4 months. It doesn't cause any problems, but the reduced air flow forces the fan to run faster.

I still fully recommend using an X800 with an upgraded cooler (X850 ones kick ass!)

Still getting 20-30 FPS in Dalaran in World of Warcraft: Wrath of the Lich King. My wife's PowerBook G4 (Radeon 9600 Mobile) gets 0-10. :P

I read on some forum they made progress on the digital output, but I have not looked into it fully as I am still using a crappy CRT.

Should have been clearer; I was ragging on using flashed PC 6800s; if you can still get Apple's 6800s or a good reference model with the original reference cooler, those are pretty good

Never get 6800s from LeadTek though, their cooler is massive and ridiculous and also sucks in a G5

I also found This (http://cgi.ebay.com/ATI-FireGL-X1-9700-256MB-Dual-DVI-AGP-Pro-Video-Card_W0QQitemZ250562435566QQcmdZViewItemQQptZPCC_Video_TV_Cards?hash=item3a56af59ee) which I think is the same card(:confused:, the RAM in not sinked)...

Thanks

IF either of those X1 or X2 cards work, they will be VGA only.

Take my word for it or try them yourself, your call.

I don't know but I'm running a great 2.7ghz with a 6800 Mac OEM card DDL Ultra and it is as fast if not faster than my Mac Mini 2.26 and the graphics response is BETTER.

Those old stock Mac Ultra 6800s are GREAT on the Powermac G5s. This is as fast if not faster than the Nvidia Quadro on my Powermac Quad and I don't know why... I've got eight gigs of ram compared to twelve gigs in my old Quad.

First off, thanks for all the hard work. I have it running the 2130 OEM ROM and the 2119 OEM does the same thing: only one DVI port works. The one nearest the card bottom.

What's weird is, you have to plug in a DVI monitor at the top of the card, wait, then plug it back in the bottom. Sometimes it takes a time or two.

After that, if you sleep it, or reboot, you have to do it again.

Can't complain I got it for $60 shipped.

The other strange thing is clocking it at 425 mhz core, which is how it came from BFG (hence the OC) gives my graphic artifacts, but I'm guessing that's just some sort of timing issue.

I'm willing to live with the OEM core speed of 400, as it runs cooler I'm sure.

Running in a G5 2.7 dual, with two Y cables feeding the card molexes and the DVD writer.

If I have two different monitors hooked in, the monitors icon at the top next to the timeclock 'sees' the same monitor twice, the one on the working DVI port.

Any ideas on how to get both working or get rid of having to plug into each a time or two? Have not tried a DVI-VGA adapter yet.

The ones here?

http://themacelite.wikidot.com/wikidownloads2

All of those are for the 6800 GT, and I have an ultra, so the core is faster. Or am I supposed to use the 6800GT ROM and then use graphiccelerator?

I just need a little hint or two, I'm pretty familiar with the tools and process. :)

The "DVI Enabled" ROMs were written because the OEM Mac ROMs gave VGA only. Fact that you got DVI at all is interesting.

Take a "DVI Enabled" 6800GT ROM and change the device id...from memory you need to change it from 45 to 40 but you should double check that. The device id will either be right before or right after "de10" id you do a search.

You can up the core and RAM speeds to Ultra if you feel the urge. Nice thing is you can reflash in OSX. Just be sure you get device id right.

So do you lose VGA and gain DVI or will I have VGA and DVI now on both DVI ports?

Listing of device ID's from Nvidia:

http://www.google.com/url?sa=t&source=web&ct=res&cd=1&ved=0CAYQFjAA&url=http%3A%2F%2Fdeveloper.download.nvidia.com%2FSDK%2F9.5%2FSamples%2FDEMOS%2Fcommon%2Fsrc%2FVendor DeviceIDsExample%2Fdocs%2FDevice_IDs.pdf&ei=GcehS8L-FJOYtge-7OCHCg&usg=AFQjCNF39mUvhFKuMe5ST8DNKB_chte7pw&sig2=JTC5cHRzuwd3us2vGNfstQ

From that, 6800 GT is 45 , 6800 Ultra is 40

Might as well up the core and RAM to stock 6800 Ultra speeds, the core will still be 6% lower than the BFG 6800 Ultra OC speed, which is what I have.

It's in a 2.7 dual system, which I'm going to guess maybe runs a little cooler than the air cooled G5's.

Card is BFG 6800 Ultra OC. (speeds from BFG are 450/550 vs OEM Ultra 400/500 speed)

I went ahead and did the following:

1. downloaded DVI Enabled (Arti) rom for 6800 GT
2. Changed the speeds to 400/550 (stock 6800 Ultra Speeds) using graphicclerator
3. Edited the device ID to 40
4. flashed the ROM

VGA (using DVI to VGA adapter) and DVI both work on either port at boot. DVI works for two monitors (1 each port) after boot. Desktop spans. (probably works during boot too, I just forgot to try).

VGA and DVI can be plugged and unplugged into either port at will after boot.

So, looks like 100% working, and no downsides. I am going to keep the stock OEM GPU/RAM speeds as an earlier test showed setting the speeds to 450/550 6800 Ultra OC stock speeds had artifacting, at least in World of Warcraft. Plus, clocking it down a little will keep it cooler and make it live longer.

Now, where do I send the ROM? :)

Forgive my ignorance, but what are you using to overclock the GPU? I have a Dual 2.7 (GeForce 6800 Ultra) and a Quad 2.5 (Quadro FX4500), and am wondering if there is a good upgrade path for both of them.

Graphiccelerator.

RAM speed would be where I would tweak it first.

I have a red PCB ATI Card, and VGA and the DVI port (using a VGA adapter) work, but I couldn't select anything other than 640x480.

The fan ran at full speed too.

You have to install the ROM Xtender as a minimum to get higher resolutions. there is also a control panel. You can get them from ATI if you select OS X 10.4 as your OS in the download support area.

I have been writing these experiments up at:

http://rcbullock.blogspot.com/2010/03/flashing-old-pc-cards-to-work-with-macs.html

OS 10.5.8 on a dual 2.7, have successfully made an FX5200, 6800 Ultra, and an X800XT. Not always a clearcut process, but read the above blog post.

thx,

AT best you would get vga ou of that, and only if it has 4 RAM chips on front. if it has 8 on front it is a lost cause.

stick with cards that are reported working

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=380195357541

or one of the 256 meg 6800gt cards...much cheaper

or get a G70 7800gs

Well, almost every graphic card has a sticker on the back, with some information like the ROM version, for example "5.70............" (this is the one for the flash process) or just the version of the GPU like "G70", maybe you should try brands like:

BFG, XFX and PNY

On the back of the Box there is a little window where you can see this sticker. Saludos! :apple:

Fortunately i don't had to (but i'm still thinking about it - it's tempting, but i'm not ROM genius, not yet). There are two threads about unsuccesful flash of one of these cards. One thread on strangedogs, second on Aquamac's forum (you know something about it, don't you? ;) - my nick there is blacksheep).
These cards have G70 7800 GTX chip on AGP (x2 keyed!) PCB, but with disabled pipes (16 only) and lowered clocks (i think it's due to lesser memory chips used).
In my country this card is not worth it's price - about $100 (for less i get Gainward Bliss). But if i ever will have a chance to get it cheaper, maybe i will take the challenge, who knows ;)

I would say the nVidia 7800 is the best, but they are very rare and very expensive. New ones go for about 280$ and used ones go for about 240$.

nVidia 6800s are okay, and go for about 150 - 200$.

The ATI Radeon X800 is better option then the 6800, and can find one for about 180-250$.

I would go for either the nVidia 7800 or the ATI X800.


The 7800 is faster, but the X800 has better image quality.

Odd, you list the systems that you have and only the monitor is mac. So are the answers you're given related to mac's?

The X800XT has one DVI-DL and one ADC port. You can only run one dual-link DVI output off of it, even with an ADC-DVI adapter. The 30" ACD requires a DL-DVI connection to run at native resolution, so you're out of luck with it if you want to run two. Your best bet for two is either a Geforce 6800 DDL (GT or Ultra), or a flashed PC card. I'd just grab a 6800--they're less than $200 if you look carefully.
