G'luck

I guess I'm out of the race then.... I won't be doing a custom cooling solution in my current setup, and I highly doubt it would gain me more than 5C. I thought I was doing well at 55 C full load, considering I'm already at a 50% overclock at that temperature. There's not much more I can do at this point to lower my temperature. I already have a 140mm Noctua 3000 RPM industrial fan running around 50% on it and turning it up to 100% will lose me at most 4C. I'm in an NZXT H440 as well with very restricted airflow.

At what temperature do the boost increments begin lowering from the max BIOS-set boost clock? Or is it dynamic, all the way down to the lowest conceivable temperature?

I've tried my own custom BIOS with a voltage max of 1.28V and power limit increased to 400W and it had practically zero effect on my overclock ability from what I can already achieve on stock.

I haven't had a chance to play with my new 980ti yet, but with the 970s, going from GPU temps of around 50c, to 35c with lowered ambients, I gained almost 40mhz. With ambients around 20c, and coolant temps at 24c, I was seeing clocks around 1630ish, with 10c ambient, and coolant temps at 14c, I saw a peak clock of 1671.

Yes, different GPU, but Maxwell is Maxwell, for the most part. Gotta keep them really cool, or they don't boost worth a ****. The cooler you keep it, the more voltage you can add. Maxwell doesn't scale with voltage well, but.....if you keep them cool.....the more you can add.

It's a balancing act....

I think I could have done that in my current setup with a 970. GM204 clocks a little bit higher than GM200, I'd say 100 MHz more safely. And considering the lower TDP, my temps would be lower as well with my current setup so 1600 would be very feasible. But on the 980 Ti, I'm just under 1500MHz, which I guess in scale of the clocks of GM204, sounds about right, but considering on stock BIOS I can achieve it, I feel like I'm missing an extra 100 MHz left in there somewhere!

Anything over 1600 with a GM204 and you're doing really well. Above 1630 and you've accomplished something.

Could be anywhere....power delivery, voltage, temps....won't know til you try. I tested both of my Classys on air to set the baselines. The 72.6% ASIC peaks at 1525, and the 75.2% peaks at 1544. Both with stock volts and stock bios.

They go under water soon...I have the blocks already, just got to find the time to tear down my loop again and get them installed.

Guys whats the best 980Ti to get if planning to run it under water <40C ?

Probably some card that is not voltage locked? Any ideas?


Thanks

Classys and KPEs.

Starting to get it figured out.

1538 core with 1.168v and 2129 memory.

nice GS.

http://www.3dmark.com/fs/7657099 trumped mine with higher clocks.

Hoping that means I can hit 23k when I get it under water.

Well isnt Classified voltage locked as well?
Quote:
For 980 Ti
1- Asus Strix ( latest version is locked to 1.212v)
2-Galax Hof!
3-Zotac AMP! Extreme
4-EVGA classified

I'm thinking isnt MSI Gaming 6G 980Ti good ? One of the best ? is it voltage locked ? Can't see anyone mentioning it anywhere redface.gif
