Power Mac G5 7800 GTX 512mb

Hi everyone, not been a member here long but I am in desperate need of some help and/or direction
I realise this is probably a heavily discussed topic but i'm another guy in need of some help.
I own a DC 2.0 Power Mac G5 and it had a 6600 128mb graphics card which subsequently died the other day. I have gone ahead and bought a Dell 7800 GTX 512mb graphics card with the intention of flashing it.
I have no problem with the flashing procedure itself, I am having trouble locating a ROM for it. At first I thought I could flash the Quadro FX 4500 2149 retail ROM but later found out that the Quadro FX 4500 ROM needs HEX editing which I cant locate a guide for the procedure. Ideally, if at all possible I would like somebody to provide me with the ROM file but in the meantime I am trying to make headway myself.
I've contacted japamac through his website to see if he could provide me with the ROM and am still awaiting a response. I realise the guy is busy so i'm trying to do the work myself. Does anyone have a link to a guide to hex edit the Quadro FX 4500 ROM to work on the 7800 GTX 512mb.
Any help is massively appreciated guys. Thanks for looking.

Ways to flash my 7800 GTX 512mb with what available roms ?

Hello fellow PPC users,
I am new on this forum, and hope I ask my quastions the right way
I got me a 7800 GTX 512mb (PC card) for my PowerMac G5 Quad running Leopard.
I read a lot of discussions about this but I never came across of a topic with instructions about how to flash cards directly with a PowerMac. I have a tool that's called nvflash 1.1 on my mac and there are options like dump rom en flash rom etc....
Is this possible to use this tool to get it done ? And can anyone provide me with a working rom running the 7800 GTX 512mb on Leopard.
Thanks in advance for your inputs.
Greetings from Belgium

Ok I will have to do that this evening because I am on my work now and my email program is not configurated.
I already had your website in my favorites but didn't know it was yours
Thx for sharing your experience with the PPC community

7800 GTX 512MB ROM??

Hello folks!
I just scored a nice 7800 GTX 512MB off ebay for a whopping $27. Of course Id love to flash this and pop it in my quad G5.
Problem is, the only two 512mb ROMS I found both dont work...
I got them both from here: http://forums.macrumors.com/showthread.php?t=1552556
One of them will give me a slightly readable display that is partially ghosted and has lines in it, and the other rom gives me an unreadable screen with squiggly lines all in it like colored "snow" on TV when theres no signal.
That being said, I noticed when I was using nvflash, nvflash saw my gtx as a "GT" when one of the ROMS flashed which nvflash saw as "GTX" in the ROM file itself, yet the other one after flashing properly showed my gpu as a GTX, yet it saw the ROM file as a quadro file. Not sure whats up there.
Currently I have a 7800GT with a silent cooler in my quad
Any help is appreciated! I already tried emailing japamac but he didnt respond :c

I had a copy of it at one time, never tested it, & it was on equipment stolen a couple of years ago.

PowerMac G5 Quad GeForce 7800 GTX 512mb or Quadro 4500 FX

Hey, best regards for all users. I have a question about changing graphics card. I'll be gratefull for all help.
I have PowerMac G5 Quad Late 2005 - M9592LL/A and OS X Leopard 10.5.8.
My card is GeForce 7800GTX 512MB and Quadro fx4500 model p348.
I'm looking for ROM for this cards for Mac G5. I want to change 6600 for 7800GTX 512MB or Quadro. Cards tested on PC are working.
Anyone can help ? I can't find any info about ROM for this cards.
Thanks all !

Both the X1900 (R580) and the 7800 GTX (G70) are capable GPUs on advanced cards, both targeting and supporting Shader Model 3.0. 3D was a focal point in development for either card.
Approaches for shader implementation are very different between the two cards.
Arguements for either abound, but, 3D performance will be a defining factor to show shader prowess.
Architecturally, the cards are very different, but, in the end, memory bandwidth, an important performance feature, is highest with the 7800 GTX; 54.4 GB/s vs. 38 GB/s for the Mac Edition Radeon.
The next X19xx card, the X1950, almost doubled memory bandwidth over the X1900.
I know guys that use flashed X1950 (512 MB) cards really like them.
Support of DirectX 9 and Shader Model 3.0 make either card more than is necessary for OS X Core Image and OpenGL requirements.
You bring up a very important point regarding application specific performance.
Games are one form of benchmark, but not always indicative of real world performance.
In Photoshop, CS4, the 7800 GTX is a fully supported card, whereas the X1900 (256 MB) card is not supported. The 512 MB version of the X1900 is supported, but doesn't help owners of the Mac Edition.
There are pros and cons with either card, eventually driver and OpenGL support being the defining point.
Early driver issues with the X1900 in OS X and a relatively short retail availability likely affect the lack of empirical data on the cards performance.
The following, though comparing a X1900XT (not the little brother X1900GT which is the G5 version) with a Geforce 7800 GTX on platforms other than Mac, the comparisons do show pro oriented application performance.
Though not necessarily applicable to OS X and PPC Macs, I thought it to be an interesting set of tests.
http://ixbtlabs.com/articles2/cpu/nvidia-vs-ati-on-amd-and-intel.html
Either card is great, either is way better than the 6600, and, as you point out, availability is an important factor.

GeForce 7800 GTX 512MB

PC users can now get a souped up GeForce 7800 GTX with 512MB of DDR3:
http://www.newegg.com/Product/Product.asp?Item=N82E16814130259
I wish Apple would offer that same card with Apple firmware for the Dual-Core G5s.

Amen to that. Cheers on your great site, too!

GeForce 7800 GTX... the best card for a PCIe G5 Power Mac?

I have started out on the rocky road to upgrade the graphics card on my Power Mac G5 Quad 2.5GHz running Mac OS X 10.5.8. The standard card, a GeForce 6600, does not do justice to this wonderful computer, and struggles with any serious video work.
The first step is easy – deciding on the best card. A little Googling shows that the GeForce 7800 GTX wins hands down over the competition.
The next needs patience – these cards appear from time to time on eBay; I will need a 512 MB PCI-e version (not 256 MB) as I am running 10.5.
I've waited a month or two, put in a winning bid and the card has arrived. Now all I need is the code to flash the ROM to make it work in myG5. Not so fast! I'll need a 128kb ROM chip! The idea of using a soldering iron terrifies me, so I'll have to find someone, who does this sort of thing for a living, to remove the 64kb ROM from my 7800 GTX and solder on a 128kb ROM.
But what's is the right spec/manufacturer/supplier for the 128 kb ROM?
If I am lucky my friend with the soldering iron may know. If not, I'm stuck. I've not been able to find this information anywhere on the Internet.
Now all I need is the right code for the ROM. It seems that there are two versions that people have used: one, which seems quite common, is lightly edited Quadro FX 4500 ROM code which does not use the full power of the 7800 GTX, which after flashing reports itself as a FX 4500; the other, which seems to be as rare as gold dust, has been fine-tuned to use the 7800 GTXs full potential. Cards flashed with this version report correctly as 7800 GTX. I really want this optimised code, but neither version is available from any of the usual places.
Can anyone please help?

I've waited a month or two, put in a winning bid and the card has arrived. Now all I need is the code to flash the ROM to make it work in my G5. Not so fast! I'll need a 128kb ROM chip!

Many thanks to japamac, who kindly sent me an e-mail which put me on the right track re finding the ROM code, editing it and flashing.
I also now know that I no longer have to worry about soldering ROM chips. Yippee! The 7800 GTX code has been 'shrunk' to fit on a 64kb ROM.

Geforce 7800 gtx card in my mac ?

Hi,
to troubleshoot a display problem with my MacG5, ( http://discussions.apple.com/thread.jspa?threadID=1121100&tstart=0 ) I would like to install a second graphic card in it. I have a PC Nvidia Geforce 7800 gtx card. Can I install this without any problem in my Mac ?
Do I have to modify anything (flash the card ROM) to make this work ?
Any info on this would be much appreciated.
Thanks.
Guillaume.

No...the card won't work. Unless you can flash it to work in a Mac. That's no easy task.

Geforce 7800 gtx power plug?

Hi-
Welcome to Discussions!
In the Late 2005 models, there is a 6 pin power connection for graphics card power. The connector is located along the top edge of the logic board, above the RAM slots, Shown Here.
The cable needed is like these:

Correct rom for Geforce 7800 GTX for Mac G5?

I just got my hands on a Nvidia Geforce 7800 GTX 512 and would like to flash it to work on my Quad G5. I know it is floaing around out there somewhere in our Ether-Space. Would some kind soul please share? Thanks

I recently acquired a Late 2005 PowerMac G5 2.3 Dual Core. It came with the sluggish GeForce 6600. I too am interested in flashing a 7800 GTX with a ROM for Mac.
Will any brand 7800 GTX qualify? I understand there may be a problem with cards having different ROM sizes. Could anyone list specific brand cards they would recommend for this purpose? I know I shouldn't expect to find any new ones. I will look in all the usual places.
Also, is it important to get the GTX and not the GT?
Thanks.

Which power MAC to buy

I am currently running a Imac, 20 inch G5 1,8 Ghz, 2 GB Ram, 4 external HD's.
Usage the standard e-mail, surfing, office stuff and digital raw photography. The Imac is fine for all the stuff, exempt the digital photography. Limits: Using Light Room or CS2 forces a 100% processor load. secondly the screen real estate. Raw files from D-70 and D-200. Ammount of files per year 5000-10000.
For the digital photography I want to upgrade in the next half year and be safe for a couple years. Budget between 5000-7000. What would be your recommendation?
Concerns on my site:
1. Power mac G5 or Intel mac
2. single screen 23 or 30 or dual screen
3. ammount of ram
4. Quad or dual

Hm.. where to start.
You say you want to upgrade within the next 6 months.
Given that, I would personally choose the PowerMac Quad G5 over any of the other offerings. It is capable of running 16 gigs of ram, and Apple reports that it can support 2 SATA hard drives, but with a slight adapter upgrade you can run 5 SATA drives internally.
I have been studying Photoshop design at college for just over a year, and I just invested $3200 in a Quad G5. I decided not to wait for the "Intel" version ( if there is one ). Apple tech reps & sales reps told me a lot of various information on the Intels, but also said that until all of the software is re-written to work specifically on the Intel, MOST of it won't work at all.
The benchmarks for Photoshop are very nice in the quad, I have Photoshop CS and it is very nice, even with only the 512mb of ram that came with the system, but I managed to bog it a little with 150-200 meg PSD files.
If you want to spend $7000, here's how I'd do it...
1. Quad Powermac G5
2. 2 gb 533 DDR2 ECC (2 x 1GB)
3. 2 500GB SATA (for all those raw files)
3. GeForce 7800 GT 256 (this card alone will help over the 6600)
4. Dual 23" flat's
5. Airport Extreme + Bluetooth for future upgrades
Cost for that is $7176
BUT.
Find a local community college, sign up for a 1 credit refresher course in anything, cost, about 100 bucks, take your student ID to the nearest Apple Store ( or Website ), and your cost suddenly becomes.... $6321
And since you just saved $855 ( minus your school costs obvioiusly ), turn around and go with FOUR gigs of DDR2 ECC ram, the 1 gig chips, not the 512's... because then you can upgrade in the future, and your overall cost is now $6861.
So you just got 2 gigs more of memory by becoming a student, AND still saved $315 (minus the college fee).
You get the idea!
Hope that helps
I know when I went down to get mine at the Store, I saved myself $280 in taxes, and then I saved $300 off the top as a student, so I purchased the 3 year Apple Care warranty. And so far, it's totally been worth it. I love being able to call and ask any old thing I need to know.
I made the big switch from a 1.5 ghz AMD chip on a Windows XP machine that I built 6 years ago.
Photoshop is definitely better now

Power mac G4 hangs at startup with gray screen

Hello all,
I have a Power mac G4 - mirrored drive door model. 512mb of RAM; 833mghz - about 50+ gigabytes of storage remaining.
I recently starting using this mac again, here is what happened:
Power mac G4 was running 10.2.1 - had never been updated; it also was capable of running classic os9 (even though I never used it)
Started using machine again a few weeks ago; let "software update" install 10.2.8 update - everything worked fine
Put computer into target disk mode to transfer files to my new macbook pro (13") - using firewire connection
While trying to connect (migration assistant) - window froze will calculating the amount of space that the "user" on the power mac totalled - power mac appeared to be frozen
Did a hard reset / power down of the power mac G4
Upon restart, power mac G4 goes through all start up functions up to gray screen with apple logo (with spinning wheel) and then goes to a darker gray screen (without the logo) and spinning wheel
Dark gray screen with spinning wheel hangs indefinitely - I've let it stay there for hours on end hoping it will resolve but it doesn't
Here's what I have done so far:
Placed power mac G4 into target disk mode again in conjunction with macbook pro
I can see all the files on the power mac G4 (and have already copied them to the macbook pro) - so I don't think the hard drive is damaged
Disconnected all non-apple peripheral devices - only had a card installed in the back - but took that out - issue persisted (did not replace card in back)
Removed one non-apple RAM stick - issue persisted
Replaced non-apple RAM stick and removed apple RAM stick - issue persisted
Reset PRAM
Started computer in single-user mode
used fsck and tried to have system check/fix issue; no matter how many times I re-run the command to repair it never comes back with a message saying no issues found - instead it keeps returning with a message saying that the issue was repaired "system modified"
Started computer in verbose mode
startup seems to hang when this appears:
"/System/Library/CoreServices/loginwindow.app/Contents/MacOs/loginwindow: (ipc/send) invalid destination"
"LayState: cannot map display interlocks."
"/System/Library/CoreServices/loginwindow.app/Contents/MacOs/loginwindow: kCGErrorFailure: CGSNewConnection"
"Cannot connect to server"
"/System/Library/CoreServices/loginwindow.app/Contents/MacOs/loginwindow: kCGErrorInvalidConnection"
"Connection called with invalid connection"
Tried re-installing with system discs
The only discs I received with the power mac G4 when I purchased are orange and say "SSW version 8.6" on it" ("iMac Software Restore" and "iMac Software Install")
Computer does not respond when holding down "C" key at startup with either disc in the drive
When holding down "option" key at startup, the computer shows the bootable choices as ONLY the internal HD - not either of the CDs I mentioned above; I wonder if it no longer recognizes the original CDs because I updated to 10.2.8 from 10.2.1 before the issue?
I also have an install disc for OS X 10.4.7 - for a friend's iMac (G5)
When holding down "C" key at startup with the OS X 10.4.7 in the drive I get a kernel panic
When holding down "option" key at startup, the computer shows the bootable choices as the OS X 10.4.7 in the drive AND the internal HD
When I choose the OS X 10.4.7 in the drive I get a kernel panic
When I choose the internal HD the startup hangs at the gray screen I mentioned above
At this point, I don't know what else to do. I believe the computer is still good because I can see everything on it when I put it into target disk mode; it just refuses to make it through the startup/login process. I have read discussion threads that suggest re-installing the OS using another computer - but I don't know how to do that. I also wondered if there was a way to tell the computer to re-install the software using the original CDs - but from the command line (in single-user mode)?
Someone - PLEASE HELP!

Sorry, SU Single User Mode, OF Open Firmware as these 2 where mentioned before.
As a test, let's try disconnecting the HD & see if it booys to any mode without it attached.
It could be the User's files or login messed up, if you want to try something a little more desperate...

Power Mac G5 fails to start up with Airport Extreme card in.

Hello.
I just received a 'new' Airport Extreme card for my Power Mac G5 1.8 (900fsb). I just installed it and it failed to start up with it in. The mac started up but without my Apple LCD and any USB devices. I did a PMU reset on the logic board and took out the Crucial 3rd party 512mb RAM and tried again but it won't start up. When I take the card out it's business as usual.
Is it the card or the mac that's at fault? Has anyone had this problem too?
Your help will be greatly appreciated.

This problem can happen if:
- the card has not been fully seated into its socket (doing that can take a firm push) or if you installed the card upside down
- the card is defective
- the card socket in the PowerMac G5 has broken or bent contact pins
Check the installation you did with:
http://www.info.apple.com/usen/cip/pdf/g5/apec_c.pdf
If you are sure the card has been properly installed, you are gong to have to either (a) try a different Airport Extreme card or (b) let an Apple dealer or service center take a look at your PowerMac G5.

Power Mac G5 Refuses to start with new RAM!

I have a Power Mac G5 Dual 1.8GHz June 2004. I know I read somewhere online that it takes 1GB sticks of RAM, and that it has to be dual channel. I went to Best Buy today and got myself 2 sticks of 1GB DDR PC3200 "Compatible with 400/333/266MHz" Dimms, and installed them in pairs. When I start them with or without my old memory, my mac starts up, makes no noises, but the fromt white LED light blinks 2 times, and does this repeadedly until I shutdown and install the old 512MB sticks. I need to get this new RAM to work in here, I just paid $112 total for 2 sticks, and I am not ready to go back to the store yet. Is there something I am missing here? Something I am not doing right?
New RAM Specs:
1GB DDR Dimm,Q PNY Technologies, PC3200 "Compatible with 400/333/266MHz"
I need to get this to work on my machine! Thanks for any help.

Is there something I am missing here?
Not all RAM is created equal and seldom does over the counter PC RAM work in a G5.
Buy and install ONLY guaranteed Mac compatible RAM.

BTW, you paid too much.
When I start them with or without my old memory, my mac starts up, makes no noises, but the fromt white LED light blinks 2 times,
That means "Incompatible RAM types".
