Curious about graphic card drivers for FLASHED cards-

Since Apple only provides video drivers as part of the OS, where do mutant, flashed cards get their driver support from?
I'm not having problems of any kind, the thought suddenly popped in my head, after many years of happily running flashed cards on a DB DP MDD G4 and a G5 Quad.
Thanks in advance.

where do mutant, flashed cards get their driver support from?
Those same drivers.
See, that's part of the "magic" of flashing; changing the codes within the ROM of the flashed card to make that card "look" like an Apple OEM. As long as the ROM coded ID is the same as an Apple OEM cousin, an ID that is included in OS X drivers, then OS X allows access to and full use of the drivers.
Knowing this, one can see why only cards that are very similar to Apple OEM, i.e. same GPU families, are the only ones that can be flashed.
You can't just change the ID of a card that has completely different architecture. There are voltages, VRAM timings, pipeline actualizations, scores of functions that are coded in the ROM but must have relevance to the architecture of the card in which the ROM resides.
OS X has drivers for many families of GPUs, but anything outside that will be unuseable, with no way to add driver support via download (like Windows).
I say "no way", but in some cases, actually hacking the drivers of OS X can allow some close 2nd and 3rd cousins to enjoy some driver support......
In your 7800 GTX cards case, there are drivers for both 7800 GT series and 4500FX series cards in OS X. The GTX has similarities to both, but usually derives support from the 4500FX drivers.

will the card work on my mac???
If not what are my other options as I have not so great NVIDIA GeForce 7300 GT 256MB

It is only when you get to the bottom, and that you want to PLAY GAMES that it is possible to answer.
Having 7300GT is worthless, unless to use 3rd monitor.
Only Windows has better Nvidia graphics and drivers for games. And if you run Windows, you can use PC card and leave the 7300GT for OS X alone.

Hi @Fodi
Welcome to the HP Support Forums!
Ok, I understand that you are trying to install drivers for your graphics adapter and the one built in to your cpu.
In reality you do not need to install the separate drivers. It is covered by the main driver for your graphics adapter when there is both an integrated and discrete gpu.
As to the Error 43 - please see this page: Expand Code 43: Windows has stopped this device because it has reported problems
Since you have tried several times you may need to remove both drivers and restart the system and let the os find the built-in graphics, before installing the driver for the AMD device.
All the various drivers for this notebook that have been HP customized can be found here:

Question about Graphics Cards for Adobe and more

Hello, for technical people I'll start by listing some relevant computer info: Asus P9x79Pro Motherboard . Nvidia Quadro 4000 2GB . Windows 7 . Adobe CS6
I have a workstation PC and have been considering ways to improve it. I'm pretty happy with both Memory and Processor, so now I'm looking at the Graphics Card. I got the Quadro specifically because it was listed on Premiere's list of Mercury Accelerated Playback cards. I have no real issues with it, but I'm wondering if I'm getting everything I can out of it. I also use Resolve often and occasionally Maya, but not often. Sometimes these other programs feel sluggish. I'd like a set up that is most optimal for Adobe PPro and AE, but is also good for Resolve. I'm less worries about Maya.
My motherboard can support 4 GPU's, but I've never had more than 1 before. I'm curious how to go about it. What sort of advantages will I get with a second GPU, how will this help me? Since I have a Quadro, should I get another Quadro? Should I run them SLI or run them independently? I've also been looking at the GTX Series, would those be preferable? If so, how should I set up my system, run monitors off 1 and use the other as a GPU boost? I really don't know enough about multi-GPU set ups, and I can't seem to find the answers I'm looking for, so any and all help is appreciated.
Thank you

Advice about graphics cards for mac pro purchase

i am considering purchasing a mac pro. i want to keep the cost down, but at the same time i am interested in longevity of the computer. by longevity i mean that as the years move on, the computer does not become "apparently" slow as quickly.
the mac pro with 2 penryn quad-core processors seems very much the type of computer that will accomplish this.
so i am now looking at the graphics card choice. i am not into gaming and (at the moment) i don't do a lot of 3D intensive stuff. i do some 3D stuff when visualizing the computer simulations of mathematical equations (e.g. in matlab).
however, with the longevity thing, i assume over the next 4-6 years applications will become more graphically intensive, webpages will become more graphically intensive, etc ...
is this reason enough to upgrade from the standard ATI Radeon HD 2600 XT to
NVIDIA GeForce 8800 GT or will i not notice this, even over the course of 5+
if i were to get the 8800 GT what differences might i notice?

Faster cards may become available in the future but they will cost you much more than the GeForce 8800 GT.
Are you planning to run dual displays? I've heard there's some problems with the #2 DVI port.
re: dual displays ... at the moment a single 23" display. however, at some point in the not so immediate future i will either upgrade to a singe 30" or dual 23" displays. thanks for the tip on the dvi port
re: geforce 8800 ... i am considering some practical logistical and financial issues right now. i was also informed that this video card is on back order for a few weeks. also it can't be installed in an onsite apple store (no sales tax).

Question about graphics cards for Equium L40 - 10X

Hi - new to this but really hacked off so hopefully someone can help me.!
I bought a Equium L40 - 10X in August and thought it was good for what I wanted, especially after seeking advice and speaking to 'an expert' at my local pcworld.
However, I think the graphics card is not good enough to support the games I have got - Medal of Honour Warchest, Hitman Triple Pack and Call of Duty 2. They all sem to recommend a nVidia graphics card as a minimum requirement. The card in the laptop is an Intel(R) 945 Express Chipset Family (I think) and the OS is Vista Home Premium.
Problems I am experiencing include loss of graphics and stuttering during play.
Can I upgrade to an nVidia graphics card or is the one I have got sufficient but I just need to change some settings?
Haven't got a clue really, so help would be much appreciated!

> I bought a Equium L40 - 10X in August and thought it was good for what I wanted, especially after seeking advice and speaking to 'an expert' at my local pcworld.
Either you was not clear enough or the expert from pcworld have provided the wrong information and wrong advice.
Fact is that the Intel shared GPU was not really designed to play the newest games.
The shared graphic card is simply not powerful enough to run such games smoothly!
> Can I upgrade to an nVidia graphics card or is the one I have got sufficient but I just need to change some settings?
NO, this is not possible because the notebooks graphic cards are fixed on the board and cannot be removed.

Sattelite 1410-question about Graphic Card

I've bought a Sattelite 1410-401 and i'm having quite some troubles with my graphic card, with moving images i can see black spots flickering through the image (no problems with stills however) ( i have downloaded the latest Nvidia drivers) wich is pretty annoying.
I'm also annoyed by the fact this graphic card doesn't support Pixel shader and that it only has 16MB RAM (not shared) my question(s) is(/are): Is there a way to get rid of those pesky black pixels and is there a way to replace or upgrade my video card?

Hello
I dont think that the black spots are a fault of a graphic card.
You say that you use the nVidia graphic driver. This is not correct. You should use the original Toshiba graphic driver or this unit. This you can find on the Toshiba website. Sometimes for watching some avi or mpeg files your need a different codex. You can find many informtions about this theme.
Furthermore you can change primary parts (memory, hdd) on you unit but its impossible to replace the graphic card.
Bye

T430S questions about graphic card

as you see ,there 3 different graphic cards to choose for your laptop.Now i'm so curious about the first one—N13M NS,which I have never heard of this before.Someone told me it's similar to HD4000 or GT610`````
But why the second choice is HD4000 but the price is higher than the first,whether it is just because of the SSD?~~~
Than, i am a student in design ,i often use PS Ai and Axure. i wonder whether N13M-NS is benefit for this kind of design softwares,and how many degree it can express ,as same as Gt630?when you use it for graphic design?

I think there are 2 graphics options, integrated (Intel) and discrete (nVIDIA Optimus). I think the first and 3rd ones have the same chip and they are described inconsistantly. The 2nd machine listed is more expensive than the first because of the SSD and a faster CPU. The 3rd is faster than the 2nd for similar reason (CPU, more memory and bigger SSD). I don't know much about the applications you are running, but in general, integrated graphics (like the middle ones) use less power (longer battery life), run cooler, but don't do well on full-motion video (like games). If your applications are doing 2D design, I doubt you could tell the difference. If you build 3D models and go through processes like rotations, the discrete models are better. The SSD will be mostly noticable in faster startup times, although if you store a lot of big files like pictures and videos, the platter-style disks have more space.

Advices about graphic card choice (best supported in Arch) ?

Hello,
I was running a desktop with Arch and a nVidia 7900GS but recently, my 7900GS died
So I was looking for a new cheap graphic card who could decode 1080p and who have an HDMI port.
Somebody told me that the AMD HD 5450 could be a good choice, or the upcoming nVidia GT 430 could be a nice choice too
But what about the support of theses new hardware in Archlinux ?
Which of theses have the best drivers ? the best performances under Arch ?
Thank you for your support

Not the latest Optimus based cards though, nvidia have just as much as said "we won't support this on Linux in the foreseeable future", leaving purchasers of such laptops with a deadweight which only pulls power. All rendering is done through the Intel card....

Need info about graphics card supported with pre pro cs5

Hi,
I checked one information about supported graphics card about pre pro cs5 on aodbe.com,
http://www.adobe.com/products/premiere/search_result.html?manuSearchVar=1&modelSearchVar=0 &supportSearchVar=0&brand=&dataFormat=&version=CS5&device=graphic&format=&buttonSubmit=
Under SUPPORT column it is mentioned for ATI and NVIDIA "Legacy support" and "Full support".
What is the difference in "Legacy support" and "Full support"?
I am not able to understand
Vinay

Premiere will use just about any graphics card to write to the screen so you may see what you are doing
For hardware MPE you must use a specific nVidia card... or a non-supported nVidia card with a small hack

Question about graphics card and motherboard

My laptop is a dv6500 CTO. I have the geforce 8400M GS video/graphics card in my laptop. Recently I was playing a game and my computer locked up. I restarted my computer and had a message from Windows 7 saying my graphics card stopped working. I than checked my device manager and it said the card was working properly. Well now it dies if I am watching a video, playing any game it lasts for about 5 mins.
I than went to the device manager and disable my card. Before my card was disabled, I was still able to loud windows fine. This is where I have my biggest question. If I disable my card, than why is it that I can still use my computer? Does the motherboard have a small chipset for video besides the graphics card? Is this graphics card welded on the motherboard or can I replace it?
I always thought on laptops the graphics card was part of the motherboard and if it went out than my screen would go out and that would be the end of it. Is that not true? Thanks for the help.

Here are the specs for your HP Pavilion p6-2371ea Desktop Computer. According to the specs, this model shipped with Windows 8 and a 300 watt power supply. To use the GTX 650 Ti you will need to upgrade the power supply to a 500 watt or 600 watt unit. The Corsair CX500 and CX600 are known to fir most HP comsumer desktop computer cases and come highly recommended. The next thing you need to do is DISABLE "Secure Boot" and ENABLE "Legacy Support" in the BIOS. Doing these things should resolve your issue.
See THIS similar HP forum thread for conformation of your issue.

I use windows7 64bit, bios is 1.15-1.06 version and the graphics card driver is NVIDIA display driver 8.16.11.8898 version.
Does anyone know this problem? I want to know it is a driver problem or a hardware problem.
Thanks for help me.

Nvidia video chips run very hot, the only thing I can recommend is using tpfancontrol and setting the fan higher.

Question About Graphics Card Compatibility

I have the HP p6-2101 that I use primarily for gaming. I was looking to upgrade my graphics card to the EVGA GeForce GTX Ti FTW edition, and I was just wondering how I could make sure it was compatible. Thanks!

Hi, There isn't any sure way to determine if a specific graphics card other than the HP OEM certified cards for your PC will work. The reality is that there is no guarantee that any particular graphics card will work in any particular PC even if the graphics card works in other PCs or even the same or similar model PCs. Know what the return policy is before you buy. Most of the newer graphics cards require that you PC runs the HP version 8 BIOS. There is a version 7.23 BIOS update available for your PC but I don't think it will help if you want to use the NVIDIA GTX 7xx ot 9xx graphics cards. ZOTAC sells some GTX series graphics cards that are compatible back to PCI-E 1.1 and these card may work with when match with the appropriate power supply. Contact Zotac for a recommendation and know what the return policy is before you buy.
