help with graphics drivers

[Quadrider10]

ok so heres my situation..... im doing a external GPU build, and im stuck at the drivers part. heres whats going on so far. i have it fully working 100% but it is lagging in all games and this lag is due to a driver conflict. the conflict is between my internal ATI driver and my external ATI driver. having 2 different drivers installed to get both cards to work properly is causing the conflict. but i NEED a ATI driver installed on my internal GPU for the external to even work at all. so the solution to this is that i need a single unified driver to be installed for both my internal and external driver. this way there is only 1 driver running and no longer causing conflict with my internal/external.

my question is this:

how would i go about editing or modding an ATI driver (.inf file) to accept my internal gpu and install.

so, my internal GPU is a ATI mobility radeon 540v (4500 series) and my external is ATI Radeon 6770 (6000 series)

now i know that my internal is not meant for the 6770 driver, however as long as it works, and i can still watch youtube vids etc, im fine with that. but i need to mod the latest 6770 driver to allow to install to my internal GPU too.

i know this has been done, spacifically for this reason, however the link to the driver is no longer existent ans i cant find it online.


my second question:

which driver would be best to use? the latest off of AMD website? regular? beta? or the driver offered through my GPU's manufacture?

thats the site im working from, it tells you how to do it through nvidia, but not ATI. also it says something about adding in my hardware IDS for my internal GPU in the (.inf) file?

I would use the driver off of the GPU's manufacture.

I would use the driver off of the GPU's manufacture.

i believe that driver is an "older" version then the newest one by amd is out.

Then use the one from AMD.

I think hes needing a mod to one of those drivers so they work both cards at same time. I have no clue how to do that myself, wish I could help.

exactly! but using the 6770 driver.

oooooohhhh k! thanks lol

found a tutorial- trying to do it now:
Mod Catalyst Driver to Add Supported Cards – BenchmarK3D

 

[Quadrider10]

can anyone help me with this?

 

[Quadrider10]

from what i understand, this is going to replace the ability to install this driver on my 6770 but allow me to install it on my internal 450?

 

[indianacarnie]

i.......... think so.......... but as I said, this is over my head. I'm going through this tutorial again as we speak. I've sent the link to someone I know to see if he can make heads or tails of it. Will let you know when/if I hear anything.

 

[Quadrider10]

thank you! heres the links to my GPU's:

ive tried it the first time and dident succeed.

external:
AMD Catalyst

internal:
AMD Catalyst

O.K. Cool, I'll relay them to him. No promises now, o.k.?

Reading the comments on the page, it seems like just about everyone had trouble the first time or two. But, made it finally.

welp, i got it to install, however its not working. the driver displayed in install manager, and it installed, but ites not working properly

 

[Quadrider10]

up its a no go. i tried to install it and it dident work, so i copied the dll's and then triied it again, and it still dident work. actually it gave me a BSOD

 

[Quadrider10]

yay! got it! i got both the internal and external running on the same driver. now, question is how well does it perform? unfortunaly, i had to install the external on my internal GPU drive if that makes sense....

 

[Quadrider10]

ok, so the graphics and performance increased DRAMATICALLY in BFBC2. i was able to play on 1080 with almost all high settings. however, it was a different story for far cry 3, that seemed laggier, and the rest of my games seemed the same maybe a little better. i dident try all of them tho. tomorrow im going to use the 6670 driver, and try a older version. idk seeing the difference in performance from what i was running previous to now was negotiable for COD and farcry. but BFBC2 was increased like 15x..... weird. i did not install CCC tho. couldn't get that far. so i guess for now, im going to create a restore point, then try again tomorrow.

 

[indianacarnie]

Well, thats SOME progress anyway I'm rooting for you man, I know how much work we put into this! Well, mostly you but you know what I mean.

 

[Quadrider10]

alright i was able to mod the gigabyte version on the 6770 and install that driver on my internal and external. performance increased A LOT, but im still getting little lag spikes here and there in my cod games etc..... BFBC2 seemed to be a little worse in performance, but i think thats because its running in DX11 now and not DX 9 or 10 but i can force it into 9 or 10 so no biggie. i think im going to leave it like this. its the best performance ive gotten on 1080 with BFBC2 and MW2 (from what ive tested) so far. and im tired of messing with this stuff.

 

[indianacarnie]

Well, at least you've gotten it playable. No help from my friend at RoG. I was actually waiting till you came back to tell you. He was curious himself if you could get it running o.k. so thanks for letting us know what you have. IF he comes up with something I'll let you know asap, but I'm not real optimistic to tell you the truth. He "does" Nvidia almost totally exclusively, but said his interest was piqued. Again, thank you for sharing your solution. And a thank you from me personally for an interesting "ride" , even if not totally satisfactory. I take off my hat to you.
