Just finished the 4th iteration of Bloodworks, this time I went back to 4 way SLI to power my new monitor setup (3 ROG PG279Qs). I had to ditch the 960 Evo raid 0 setup, as I don't have enough lanes to run 2 M.2 ssds after having four GPUs in 16x 8x 8x 8x. However, using the system I can hardly tell a difference anyway, especially with ROG Ramcache.
4 Way SLI in 2018 works better than you would expect, yes in newer titles the scaling is worse than in previous years, however the performance gain is there and all four cards are utilized. The EVGA Pro V2 4 way SLI bridge has been wrapped in carbon fiber and I inserted 9 layers of red film to make the LED shine red. I also bent the pins on the metal connectors of the bridge to grip the cards better and now it shoes up as "High Bandwidth' so I don't get the annoying message to upgrade my bridge. If you couldm't tell this PC is Asus ROG themed, I'm not sponsored by them I just love their products and design. The reason I'm not using the ROG 4 way enthusiast bridge is that the EVGA has metal connectors and runs at 650mhz while the Asus bridge is an "LED Bridge" meaning it only runs at 450mhz. That is still 50% higher than the standard SLI bridge speed of 300mhz, however when your running four cards you need all the bandwidth you can get.
I went with ROG Poseidon cards instead of Strix cards for three reasons. One, I prefer the back plate aesthetic as I think it looks cleaner. Secondly, Two, the Poseidon cards are binned better and overclock higher when on water, and even higher when on custom waterblocks. And lastly, I already had two Poseidons from my previous iteration Bloodworks and I didn't want to go through the process of selling them and buying Strixs. If you didn't know, the ROG Poseidon 1080 TI and ROG Strix 1080 Ti PCB is identical so waterblocks made for the Strix fit the Poseidon as well.
Overclocking has been great, all four cards hit over 2030mhz at 115% power target and no additional voltage, and all cards can do over 12ghz on the memory. The 7980XE has also been easy to overclock, I have it running 4.6ghz on all cores at 1.225v, this is slightly lower than last time but I am trying to keep temps down and I'm not trying to burn out this CPU like I killed my 6950X last year.
Temperatures are pretty good considering how much hardware I have in one loop. The CPU idles at 40c and goes to 75c at load, while the VRM also sits at 40c idle and goes to about 80c at load. The Poseidons are all in parallel, and sit at around 35-43c idle depending on the card and at load sit around 45-62c again depending on the card.
As far as cooling goes, I am using 3 radiators all EK. One 360 PE, one 480 PE, and one 360 XE in the basement. I am using an EK R6E monoblock to cool the CPU and VRM, and 4 Bitspower 1080 TI Strix waterblocks to cool the Poseidons. I am also using the Bitspower 4 way Terminal to cleanly run all four cards in parallel. For pumps, I have a Bitspower dual D5 pump combo. All my fans are Thermaltake Riing 120 red fans. The ones on the top and bottom of the case I have also applied ROG fan stickers to just to spice them up a bit as I have removed all the ugly Thermaltake stickers using a heatgun.
I also wrapped the midplate of the case, and all the radiators in carbon fiber, I think it makes the PC look cleaner and I like the aesthetic of it.
I appreciate any feedback, thanks!
