So got my water loop back together last night and did some testing. Lowering the voltage allowed 2126 which was solid for a while until the room heated up a bit and temps started going north of 35*. No hard crash but frames started to stutter and artifact.

I'm considering a shunt mod but at the same time, given the "gains" I don't think its worth it...

shunting seems silly honestly.

Much rather find a way to just get control over the voltage controller.

We're also in two different boats. you want high FPS in 1080p, which i'm guessing wouldn't even require a second card based on 1440p ultra running 70-90 most of the time. Really I believe the issue is the same as its always been. Two cards doesn't do much for ya at higher resolutions if you're already nearing your memory bandwidth cap.


I really do hope you get the epic experience you expect, I do. I'm not trying to talk anyone out of anything (no matter how many times you annoyingly say it, it won't come true), I'm pretty sure that's just your tribal nature kicking in & improperly deciphering these figures on the screen.


People just gotta remember - one beefier card always wins against two mid range cards (specially when the beefier card has higher memory bus!!!!) UNLESS!?!?! anyone remember?! you're gaming in resolutions low enough to not max out the memory bandwidth, as memory bandwidth doesn't scale as most expect it to, in SLI.

it's a funny time right now though, 20 series sucks & many of us are experienced that first hand, thus the only other thing to do is slap on an extra 1080ti for the one outta ten times its gonna work well.

as I stated in the beginning of all of this like 2 weeks ago - I'm not trading in my 2nd card until I see how it fares on my 3440x1440p alienware next month. That however won't change the fact 1 in 10 games support SLI, and that its a dead technology being replaced by NVLink. The more DX12 titles we see, the less SLI titles we'll see, until they get that part all ironed out, which may take a couple more years & we currently get maybe 1 outta 20 with native support, n can maybe get 1 in 5 to work with tweaked support.

I only have anecdotal evidence, but when I was trying SLI on the GTX 900 Series Cards, no matter what my frames were, the experience felt terrible and I opted to play all games at lower frame-rates with a single card.

yep, that's a pretty common response from folks... there's an inherent latency. The better solution these days would be a top tier card & a frame pacing monitor.

Fallout 4 & Deus Ex were the last native-sli titles i know of that run beautifully in SLI. Pretty much everything else requires tweaking, and ends up having a tell or two (unless you're on win7 apparently )

- turns out my weird data corruption issue has spread, more titles won't load, etc so I'm rebuilding my RAID this weekend after replacing my ancient sata cables.

hopefully that'll fix the weird launch issues, & non-functioning Sli issues I've been experiencing in titles where it should work, but doesn't.

also - I totally forgot about cpu lanes, so my 8TB of NVMe on the ASUS expansion card has gone into storage for the time being until I upgrade back into the higher lane count CPUs... or pawn off my 2nd TI & get a g-sync monitor.

Hey guys,

I came upon an offer of some ASUS 1080TI FE cards recently. Those cards have been purchased in the middle of 2017 and used for mining (obviously) for an year. After that they have been removed have been staying in their boxes ever since. I've read a lot about mining cards and what condition they may or may not be in, but the price is very good and I have always wanted to do a dual GPU setup ( I already have one 1080TI) so... Is it worth it to go SLI with 2x1080TI's in this day and age? I don't game a lot (almost not at all) but I like to do benchmarks and play with settings, hardware, tinker and so on. My monitor is a 34" UWQHD 3440x1440 so I'm pushing about half the pixels for 4K...
Basically I can get 4 of those 1080TI's for the price of a single brand new RTX 2080TI and to be fair I don't like all that RTX snake oil...

SLI has latency issues over single cards so some people complain of stuttering and such. Benchmarking it would be good though, but not so much for gaming.

I think it depends in if your CPU is fast enough to keep up. I have met someone recently in steam chat and talked to them directly and with a 9900K system, and DDR4 @ 4000, they're reporting to me zero latency/stuttering issues with two 1080 Ti's driving [email protected] But same user also told me that trying to do the same setup with a 1st gen ryzen had bad latency/stuttering. So.. depends on your system.

Also with any setup.. either nvidia SLI or AMD CrossFire you need to be prepared to fiddle with profiles to get your games working 100%. With AMD it requires a 3rd party program to run in the background to make it work (RadeonPro) and with Nvidia you can edit nvidia's profiles directly with no 3rd party background programs so.. pro's and cons of either setup.

9900k with DDR3? weird.

yes CPU helps, but adding a second card 100% adds latency, even if your homie with the best sli experience on earth is clearly the norm
