Thanks! Reassuring. I'm contemplating to upgrade to 9900k also. Considering that I'm gaming at [email protected], I do not need an OCed 9900k for games, I think I can downclock/downvolt it to 4.5GHz (thereby keeping it approx. as cool as my old 3770k is) which should be enough for not to bottleneck Rad 7 below 60 fps.


UPDATE:
So that's what ([email protected],090) I've eventually got in firestrike torture (99.5% stable https://www.3dmark.com/3dm/40238622) when trying to have stable >2000MHz for games (six stacked screenshots).
A dip to 1906MHz can be seen when junction touched 92 C, so its all about cooling. At [email protected],081 this test crashes 100% of time, at [email protected],090 which substantially the same in terms of the frequency curve this test is 5/5 successful runs with 99.(2-7)% stability. D5 pump at 100% pwm coz it cannot be heard over six noctua nf-f12 fans (push-pull over the radiator) running at 1000 rpm. Overall, it is less noisy then 55%-stock radeon 7 fan, for real games, I think, I can adjust D5 to 50% pwm and fans to about 800 rpm.

Guys, are you using registry power mods or 120% enough for reaching those numbers?


The final built i did for rad vii (cpu is [email protected]). Will be trying to get close to 2Ghz without power mods.

WannaBeOCer Are any of you able to overclock the your card with the latest 19.10.1 driver? If so which OS version do you have installed and build number? Which chipset/processor?

But lowest frequency and highest junction temp is during firestrike torture. It was around 1950-1970 Mhz in firestrike torture, while in games and in timespy torture test its above 1980 and hits 2000 very often. At v1,054 firestrike torture always crashes at 1st or 2nd run. v1,077 is ok, but I think there should be something stable at between. I just hate to spend time for 3dmark, but in games (gta5 and pubg) even 1,054 is perfect.
Yes, it is the hardest test, taking temps to 40/100 and 360|W power usage. I have real 2030 MHz reported by Afterburner there. (with 2080 set in wattman).

The ability to maintain clockspeeds depends on 2 things: 1) ability to efficiently cool the card. In the case with aircooling it is UV.
2) ability to provide enough power not to spike down.
The answer to your question is: for the stability of the card you only need efficient cooling.
For even nominal performance, you need a lot of juice anyway.

And, of course, 480mm radiator exclusively for video card with full cover I will post 3dmark scores in the evening.

Looks like you have space for radiator on the top of the case.

In your case x2 power for ~x1.15 frequency... this is crazy
Well, a bit more. I do have really stable frequencies at real 2040MHz repored by monitoring, and it does not jump up and back like on air...
What I like, is that the card is very close to 2080ti stock now. And it is really a beast in numbercunching
Power, it's my winter heating system, individually suited near my legs I turned off heating in my room (almost)

I have Ryzen processor, who does not like to be heated by water from Radeon or it drops clocks.
