Morphing nForce4 Ultra into nForce4 SLI

Half Life 2: x16 vs. x16/x2 vs. x8/x8 (nVidia SLI)
As seen in past SLI reviews, performance with SLI improves more as resolution and "eye-candy" increases. The range of performance improvement was from a small 6% at 1280 with no AA or AF to a significant 61.0% in 1600x1200 with 4xAA and 8xAF. Performance improvements are even greater when going from a 6600 GT, 6800, or 6800GT to a dual card SLI mode. So consider this to be the smallest performance increase that you will see since we are using the top-line video cards.

i did the mod last night. it took me 2 tries, because i guess on the newer boards they have a dot of glue over the resistors that i had to scrape off with a knife. a dot of conductive pen (purchased at radio shack for $13 and change) was all it took.rancidmonkey - Saturday, February 26, 2005 - link
Hi,This is my first post to Anandtech. :) I have ordered a DFI LanParty NF4 Ultra-D from Newegg, and this "SLI-enable" mod is exciting, mostly because of the "budget-minded gamer future upgrade" benefit mentioned by a couple others here. However, what do you all think of possible compatibility issues arising from attempting to pair a 6600GT purchased this month with one purchased 10 or 11 months from now? Could imperceptible changes in the manufacturing process make two seemingly identical cards not work together in SLI mode? I suppose if you really are budget-minded, you could scour ebay for a second-hand card purchased around the same time as yours.
What do you think?

please forgive me if my above comment about PCCaseGear and the bridge was already covered here. I am in a rush and only read the last fourth of posts...cyburzaki - Thursday, February 24, 2005 - link
DFI sized bridges are definitely being made by at least one third-party, since PCCaseGear in Australia includes with their Ultra-D boards an SLI bridge. But I emailed them and asked them the name of the German company that makes them, and they refused to tell me.http://www.pccasegear.com/prod1847.htm

Wesley (or anyone else, for that matter),Where can one get the SLI bridge to use with this mod?
Thank you!

I bet it is easier to get the SLI bridge for this mod than it is to get an Nforce4 Ultra to try it.Wesley Fink - Saturday, January 22, 2005 - link
#77 - DFI tells us all boards that will reach the retail market will have the modifications we are expecting. There is a new BIOS and several updates of components to improve performance and memory compatability. These changes have been made to production boards and the first boards off the line are also being updated post-production before release to the retail market.ChineseDemocracyGNR - Saturday, January 22, 2005 - link
By post-production modifications, do you mean that the first boards to hit the market will not have these improvements?Wesley Fink - Saturday, January 22, 2005 - link
ALL -As a result of feedback to DFI on the initial testing, DFI is making a few post-production modifications to the board and BIOS to further improve memory compatability and overclocking. There is nothing wrong with current overclocking performance, but we want to bring you a review of the final production board, so we are waiting for the boards with modifiactaions to arrive. Those are expected by the middle of next week. We should have a review of both the DFI boards around the end of next week unless there are further delays.
