*FIXED!!!! FINALLY!* -No SLI option/screen black problem .. - Page 4

post #31 of 68

Yes you are right - the palit has an unstable factory overclock! If the card is clocked at the clocks from factory, it can only load the desktop without crashing. If the voltage is upped by approx 30 mv, it can play any game/benchmark i throw at it!

Thats why i want to flash the bios on both cards, so i can flash to an identical bios, with a setting that is stable on the palit card !

I have found a procedure that works now.

Turn on the computer - both cards yield error 43!
Go into device manager, and disable both cards!
Restart the computer, and enable just 1 card!
Restart the computer with 1 card enabled in device manager. The driver reckognizes, and res. is high.
Enable the 2nd card in device manager, and the SLi option becomes available in NVCP
Enable SLi!
Now the res. goes to 800x600, and one of the cards yield error 43!
Disable the card.
Enable it.

Boom - SLi is running flawlessly without any errors, just until i restart the pc, and i have to follow above procedure again .. good i have an ssd, so it doesn't take so long to boot to windows lol..

And i bought nvidia due to the flawless SLi support sigh ..

I can't there's no warranty - waterblock installed, and RMA sticker broken.

I don't think it's defective though - unstable factory clocks have been seen before

now you ran both cards at same clocks right? you have to either oc your evga gtx 580 or downclock the palit gtx 580. otherwise SLI might not work.

Yea thats what i thought, so i think im going to flash the cards to identical specs.

The thing is, i cannot clock both cards to the same clocks before sli is enabled, otherwise it afterburner won't reckognize them, so i think i'm going to flash then to identical specs and see if it helps

It seems that this is the issue.
Which card will you flash?
the Palit or EVGA?
I guess since the Palit is the bad card you don't need to touch the EVGA to do yourself a brand new issue lol.
You can just mod the Palit card bios to stock speeds and the stable voltage instead of trying the EVGA bios to be safe.
you can use Fermi Bios Editor to mode clocks and voltage (I don't know if it does support GTX 580 or not)

Best of Luck

Thx for the good luck But you're right, that's exactly what i will do! I will flash the Palit with the EVGA bios, but simply with a higher 3d voltage prob. 1030 or 1050 mv to be sure, since it proves to be ROCK stable at that voltage. Heck, i have even run the palit at 1.163 and 990 mhz core!!! so i don't think there's anything wrong with the card, that particular chip just needs more voltage for the clocks

I didn't pay attention that you earlier said one of your cards run at 782 and one at 772.
I can give you at least 70% assurance thats your issues. SLI won't work with different clocked cards. you have to run the palit card at 772/1544/4008 just like the EVGA card .

I am in the process of flashing now - i don't feel good about doing it, but i want this setup to work now! I just hope i won't brick anything :S Atleast i have 2 cards for recovering one if i brick it lol. I really hope this is the fix !
