 When you hear the letters SLI, you probably think of grand gaming machines that can crush anything like Grrr, grrr, GTX 1080 Ti, SLI, Four Titans, grrr. But what about the other end of the spectrum? Just how bad can an SLI gaming machine be? Well, once again, Linus Tech Tips is bringing you the answer to a burning question that nobody asked. Cooler Master's 25th anniversary edition, Cosmos 2, features a unique dual curved tempered glass side panel. Check it out now at the link below. So it all started while we were working on cheapest new egg PC, and we stumbled across something astonishing. Hey! Our graphics card supports SLI, and we've got two of them! So of course, we immediately set out to build what would end up being the cheapest and almost the worst SLI rig possible. But the reason that we bought two of those GeForce 8400 GS cards was actually in case one of them broke. And it's always a good plan when we're ordering super cheap and old stuff for videos on a deadline. And sure enough, while attempting to test SLI, one of them broke almost immediately. But honestly, they weren't actually the worst SLI capable cards that Nvidia ever made. And if we were gonna have to buy more cards anyway, we felt like we should really go for the worst of the worst. I mean, effectively, we were aware that there wouldn't be much difference between a turd burger and nail clipping soup. And nail clipping soup. But here at Linus Tech Tips, we only accept the best of the best or the worst of the worst. So I present to you, hailing from the year 2006, the Nvidia GeForce 7100 GS. The worst Nvidia graphics card to ever feature support for SLI. These things are so freaking worthless that it's hard to find one of them, let alone two. I mean, on eBay, there were a couple available, but no matching pairs, and that's ignoring completely unreasonable shipping costs. Even our industry contacts like EVGA and ASUS didn't bother holding on to any of these, so they had nothing kicking around. Because why would they? Fortunately, though, we have awesome fans. And after a Twitter post, Matt and Archer Grimes hooked us up with these beautiful specimens. Thanks, guys. So, the GeForce 7100 then. A card that was basically a rebrand of the worst card on the market from the year 2004. The GeForce 6200, but now with SLI. So with a whopping 20 watt power draw, a blistering 350 megahertz core clock, and 300 megahertz memory clock, these things are only outcomputed by the most experienced Abacus users. Hailed in their time as only acceptable for office use, and anything but sensible, we're expecting running these cards in games to be about like taking your dad's lawnmower to Le Mans, and he's got a push mower. So we toss them in our system and, huh? Where's the set SLI configuration option? I mean, it says so on the web page. SLI. Maybe it's Windows 10 screwing with our drivers. But in Windows 7, it doesn't work either. Documentation for running these guys in SLI is basically a couple of jokes about it on tech forums from 10 years ago, and then one German review website that did get it to work. So there was still hope. After some more digging, we found out that only X58 boards and older will work with the SLI drivers. So rock on then, time to- Oh crap. Then while installing the board on our bench, one of the capacitors literally fell off its leads. So after stealing a similar enough one off of another dead motherboard and soldering it on, we were back in business. Maybe. It still wouldn't work. After some more digging, it turns out that maybe only 32-bit versions of Windows will support this old of SLI, making the 48 gigs of RAM in our system look a little imba and unnecessary. But we decided to leave it all in there anyway, because it looks cool. In the end, almost hashtag out of ideas, we blew the dust off of our CD drive, burned ourselves a copy of Windows XP 32-bit, and spent about a morning in driver compatibility hell until finally- Yes, finally, we had the pinnacle of piss-poor PC performance. So first, we tried out some games using one of the 7100s to set a baseline, where it performed about as well as you'd expect. One and a half FPS in 3DMark 2006, like 10 in Crysis, and actually a pretty good experience in Halo Combat Evolved and well over 60 frames per second in 3DMark 2001 SE. So we were hopeful about its performance with SLI enabled, until, well, everything crashed. Almost immediately. 3DMark 2001, 2006, Halo, Crysis, and Half-Life 2. The SLI performance of this machine completely exceeded our expectations for how crap it would be. Truly the definition of unplayable. The only 3D object that wouldn't crash the computer immediately was the 3D text screensaver, and even that had stuttering issues. And we aren't talking soft crashes here. You open a game, boom, and you'll be reaching for the reset switch. We tried a bunch of different drivers from 91.45 all the way up to 307, since we wanted at least one game to work so we could compare performance, and they all immediately died with SLI enabled. So you might be asking yourself then, why bother releasing this video at all? Well, I guess it's because we learned some things along the way that we felt were important to pass along. One, driver support for 11 year old graphics cards isn't great. Number two, Windows XP isn't as good as we all remember it being. Number three, capacitors can fall off old motherboards pretty easily, then can be fixed pretty easily. And finally, four, holy sweet shit balls. Whatever you do, don't run the 7100GS in SLI.
