Goooood run...I'll try more on ln2

Great efficiency!

These are not real clocks!

Boost should be around 1730...

indeed...

...thanks guys ;-) ...real boost clock would have been around 1740-50 or so ...the screenshot shows you the nominal ones used; don't know where the once listed above came from as I normally leave that blank due to special Bios / clocks ...LN2 later, after I exhaust whatever headroom I still have left w / o it, but still just exploring these new cards > can hardly wait for 'Big Daddy Maxwell' / AMD 390X / stacked memory if these 980 Classifieds are any indication

However... good job on water cooling!

These Classies are excellent on air/water cooling. Haven't seen any other brand match their clocks on ambient temps.

...certainly happy w/ the cards, though I think all 980s react well to good cooling,but Classies' cold plates are a real bonus...cooling system for GPUs = total 1080x60 rads, 3 pumps, uni-blocks, cold water feed etc...trying to keep peak load temps at around 20 c or below

I've added the clocks, try adding them on all scores as it makes mod work easier.

...ahh, was wondering...I'll try to add the clocks per GPUz from now on, but real boost w/ boost-enabled Bios and drivers seems to depend on order of ASIC w/ multi-GPUs, even before custom BIOS...and in Unigine 'Valley', the above run settings actually display as '1876MHz' on water which is utter hogwash :-)

killer run joa, i cant wait to try my classies out soon too

Killer run. Check gpuz SENSOR TAB and use the actual boost clocks your cards are boosting to during the bench. We all know reported boost clocks by gpuz or valley are wrong.

Tx Szeged & SDhydro - I may yet mod the Bios towards boost-disabled anyways - just too little time right now as work is super-busy...haven't even done ANY SLI / only a handful single 980 Cl runs...2 of the 3 cards might reach 1800++ w / heavy water-cooling and sane voltages

Btw, what was the vGPU? I'm hitting 1740+ with 1.45V on a single Strix and chilled water.

...1.4 - 1.42ish (range for 3 cards) on cool water...won't go much higher yet until I really have a grip on these cards /- a bit tricky to get one-size-fits-all vGPU as ASIC ranges from 66.9 to 88.9 % for the trio

Thanks for the info. I don't want to go above that as well, since I plan to freeze it anyway.

...same here; 66.9% card is the 1st candidate when I get to sub-0 later, but in the mean time, don't want to fry it on water...btw, I've seen people post elsewhere that they were running 1.47v @ air ~~~(

Only on OCN

Insane clocks on water. Well done!

Killer run Joa, have to say this run is very impressive given the cooling. And props to EVGA, these cards are monster a team mate has his running 1820 on water for Catzilla!
