Sli possible on gigabyte x58-ud3r?

Hello all! Long time reader but first time poster. Usually my answers are a quick search away on these forums but it seems I finally found a question noone has asked (which probably means the answer is obvious to everyone but me LOL).

So as in the title of this post, I have a Ga-ex58-ud3r and with the recent release of the sli varient (identical visually) I was curious if a flash to the sli bios (is it even compatable?) would allow for sli'ing my gtx285?

Any help appreciated! Thanks guys 🙂
 
First off, Welcome to the Forum...

To answer your question, no...single slot board. The UD3P has dual PCI-E but will only do cross-fire. I have the UD3R in my second system and just love it.
 
Thanks for the replies guys. Actually the x58 version is in-fact dual PCI-e and native crossfire. ;-) Gigabyte just decided to release an identical board with SLI enabled instead. This makes me wonder if sli is simply a bios flash away.

 
Yeah from what Ive read and what nvidia said, its fairly easy to unlock the BIOS code that allows SLI on a non SLI x58 board. But, noones tried to edit those bios's yet since those boards arent that in high of demand or common as all the ones that have SLI anyways.
 
If you want to find a person who can unlock the bios code or work on it, you'll definitely find him or her in XS. There is a guy working on the MIIF bios in thread "Maximus II Formula ...New P45 king?"
 
Hey all, I noticed this thread got alot of views so figured that I'd post my findings on this issue just incase others are wondering as well.

From the FiringSquad review:
The GA-EX58-UD3R also ships with two PCI Express graphics slots, with full support for ATI?s CrossFire multi-GPU technology. (In a CrossFire configuration both graphics cards would run at full x16 speeds.) In order to get official SLI support, you?d have to opt for Gigabyte?s GA-EX58-UD3R-SLI which currently sells for the same $209.99 price tag as the UD3R on Newegg, only there isn?t a $15 mail-in rebate being offered at the moment.

If you?re comfortable with BIOS flashing, you could theoretically flash the UD3R to support SLI by using the GA-EX58-UD3R-SLI BIOS, but you?d still need to go out and purchase an SLI bridge connector if you don?t already own one (or the connector you have won?t fit with the GA-EX58-UD3R). These typically sell for $7-$12.

Of course, the GA-EX58-UD3R-SLI comes with the bridge connector in-the-box, so purchasing this board would be the easier solution if SLI is important to you..

This is confirmed as working. I bit my tongue , shut my eyes and pressed the flash button on the SLI bios with, so far, good and stable results.

Take care guys 😉
 
NICE! so just to make clear you successfully flashed the SLI version of the BIOS onto the non SLI ud3r????
I have the non SLI Ud3r and was wonderin same thing. What version of the SLI bios did you flash?
Now, the next question...have you actually tried SLI'in 2 nvidia cards with that board?

Hi there, I do hope you will check back after the reply here 🙂
Im in the same scenario as you, trying to flash my bios to SLI version on my ex58-ud3r.
The problem is I cant find a bios flash tool that will accept the incorrect microcode from the SLI bios, id love to know where u got yours from!
I had assumed that this board would do SLI (I follow design logic rather than marketing shpeel) and ended up first viewing a thread on tweaktown.com that described the first person to do this process on the EX58-UD4 board. Since the UD3r and UD3r-SLI use the same bios type and the boards look identical i assumed the same was possible then found this thread 🙂
The article on tweaktown mentions that u need a flasher called "spiflash.exe". This seems to have been released by some clever Asian chappy and it looks to be a word play on gigabytes own "flashspi.exe" tool used to flash these bios's.
I know thats the file im after, I guess its just the same tool modified to ignore the micro-code mismatch.
But despite registering at a few sites with the help of google translator im still unable to get hold of that file. If anyone has any information on where i might download it (or if OP could re-host the flasher he used) I would be very happy 🙂




 
Where will you get the SLI bridge? Second, why would you want SLI now if you didn't when you bought the board? Third, why not just a get a GTX 295?
 
1, I already have the SLI bridge from my last board (a8nsli)
2, I already had two cards
3, i cant afford that and want to use the two cards i already have 😛
