MSI Geforce 7800 GTX with MSI Nvidia GeForce 7800GT in SLI?

Hi. I bought the MSI Nvidia GeForce 7800GT a few months ago with the intention of buying a second to run in SLI. Now i can't seem to find anywhere that sells it at a decent price. Originally i bought it from www.ebuyer.co.uk but they have discontinued it.
Could i buy a MSI Geforce 7800 GTX and run it in SLI? They should have the same gpu and the specs aren't that different.

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!

2 MSI Geforce 7800 GTX Duds?!?!

I just bought two MSI Geforce 7800 GTX's and both seem to be faulty.
I've tried them in single mode, SLI mode, and on multiple computers
Both computers are MSI K8N Neo4 Platinum / SLI
2 GB Corsair RAM at 3 3 3 8 1T
One is an AMD Athlon 60 3000+
The other is AMD Athlong 64 FX-55
Both cards freeze on starting up windows right before the Windows XP PRofessional Loading screen. This occurs in SLI and in non-SLI mode running one card, as well as running on two diferent motherboards
Not only does it freeze when starting up windows but when trying to do a windows install as well freezes on the "starting up windows" portion when i tried to reformat
I have tried updating the BIOS for the MSI boards, it did nothing.
This was an upgrade from two MSI 6800 GT's
Should I return the pieces to the retailer?
Thanks =/

Geforce 7800 GTX won't fit in MSI K8N SLI !

Hey we all know the problem with MSI K8N SLI and 2 Geforces 7800 GTX:
http://www.theinquirer.net/?article=24239
What revision of MSI K8N SLI will fix this problem ? ( i need this info when i will go to store)
and can you tell me is this problem egzist on Microstar K8N SLI Diamond nForce4 SLI mobo ?

sorry man i'm lazy sluggard, my women tells me this everyday ...
LOL, well I have this MOBO and due to the "issue" I will be going to a single card it looks like...but to tell the truth, I never saw that much improvement with dual 6800ultras. I am thinking one new 7800 will be more then enough. Only time will tell

K8N Neo3 with a GeForce 7800 GTX?

Hello, I got a AMD64 3200 (socket 754) processor with a K8N Neo Platinum motherboard.
I want to upgrade my videocard and I am thinking of a GeForce 7800 GTX. Because of the futurure I want a pci-e card, so I am thinking of changing my motherboard to a K8N Neo3 motherboard. I searched everywhere online (including this forum and the msi site) but I can't find if this motherboard is compatible with a GeForce 7800 GTX. Can anyone provide me with the answer? Thanks.

Quote from: Luke51087123 on 25-August-05, 08:51:29
neo 3?? thought there was only 2 and 4. Im prob wrong but the nforce 4 chipset is the only one for pciE
I think you are right about the nforce 4, but the K8N Neo3 got the nforce 4. Here is the link:

After Effects uses your CPU and RAM Primarily, not the GPU.
You only need NVIDIA CUDA for one function: the acceleration of ray-traced 3D compositions. Your newer Maxwell NVIDIA GPU does not contain the OptiX Library necessary for this function so it will not ever work for accelerating ray-traced 3D compositions. Sorry.
The After Effects team is no longer working on this feature and suggests that you use Cinema 4D Lite (bundled) for your 3D work instead. There are also some great third party options for adding 3D elements to After Effects compositions like Invigorator Pro and Video Copilot Element 3D.
Hope that clears things up.
Thanks,

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.

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.

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... 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?

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 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:

Duel Monitor Calibration with the NVIDIA GeForce 8800GT

I have ordered a Mac Pro with a NVIDIA GeForce 8800GT and would like to know whether it supports dual LUT's? I have also ordered two 30" ACDs and would like them both calibrated for photo editing work in Aperture.
Looked at the NVIDIA site but couldn't see the answer.
Many thanks...

In short, no. The only way to get a LUT for each monitor is for each to have its own GPU. Having said that, I have the Radeon 1900XT driving 2-21" LCDs and have managed to get them really darn close with a good calibrator. If it's really important for you, buy a second card.
This is from the Nvidia knowledge base and the answer is the same for Macs.
+"Windows XP detects NVIDIA GPUs as a single processor even if the GPU supports dual monitors. This prevents the operating system from natively allowing two separate ICC profiles from being used on a single graphics card. This is not a problem if a user is running dual monitors and each monitor is running on a separate GPU.+
+Microsoft has provided a utility for users with two monitors running off of a single GPU who wish to calibrate both monitors. You may download this utility from the following URL:+
