GTX 1080ti or Custom Variant? - Page 5

That's an astounding amount of power - like 492W total for the card if my math is right. It's bursts, usually its pulling 15-20A on the 8 pin and 0-10A on the 6, but still. I don't think the VRM is the weak link here.

Got mine running at a stable 1987Mhz, which is conservative. Was able to benchmark around 2012-2075Mhz a few times. Memory OC'd +500 aka 6,000Mhz is MOSTLY stable, it seems to prefer +400-450 for every day.

Card's a beast. My god do I hate the founders edition blower fan though. Can't WAIT for my watercool.de blocks to get here.

So do you still think it'd be best to go with a 1080Ti FE if you decide to change the cooler to a waterblock anyway? No advantage of having an AiB card?

I'll tell you for sure next weekend when I get them under water but lemme put it this way - even at "only" +100 GPU and "only" +350 VRAM it's such a beast I don't care hahah

Will H2O cooling guarantee you'll never throttle?

It should (most of my other cards I've put under water haven't even come CLOSE to thermal throttling).

Promised update (a bit late). TL;DR yes going under water helped a TON - I was actually able to go well beyond my on-air OC (despite not thinking it was thermal throttling - I think its transients of high activity / high current moments). I saw it pulling 40+A on the 12V rail!!! (42A on one card, 45A max on the other) Actually had to switch PSUs to my AX1200i as my other one was hitting OCP and rebooting. Anyhow, I'm super impressed by these Founders cards and have benched at 2025-2050 stable. I do think the AIB / partner boards could probably hit 2100, but frankly I saw almost ZERO difference between 199x Mhz and 2050 when it came to Time Spy scores - maybe 1.5-2% at the VERY most, for what, several hundred dollars more (once prices stabilize).

EDIT: crappy phone pic attached of the Watercool blocks (love them!) in my S8 - ignore the horrible cable management and all the bubbles, I was still bleeding the loop (running two D5s made that quick work haha).



EDIT2: I figure, I should have linked my Time Spy Results duh

Do you mean the AIB 1080Ti's could do 2100 w/the stock coolers or when put under H2O?

I had thought the Pascals were supposed to be more power efficient than Maxwell?

I think the AIBs can do that EASIER under water but some may on air. Much of the benefit IMHO of AIB is the cooler, not the chips / board or even the VRM these days. AKA going to water, I went with Founders for that reason (and frankly cuz I didn't want to keep waiting haha).

Re efficiency, they are - MOST of the time they are cracking along under 200W, but they burst up HIGH (whereas my old Maxwell Titan Xs would be running 3-400W all day long and burst to 425).

So one of your 1080Ti's will burst to 45A draw at 12V? That's 540 Watts for one card!

Do you think a universal water block could work as well for 1080Ti's as your full coverage water block?
