It's really not liking going above 150

Man tomorrow can't come soon enough. Do you mind if I contribute a bit to this thread once I get my card? I'm not a huge gpu overclocker but I do plan to oc this one.

Yes for sure! That would be awesome! The more data the better :D!
 
Memory +500/Core+160/voltage+25: 14518 maxtemp:58C

Two crashes with this settings... only lowered memory.
Memory +800/Core+160/voltage+25: crash
Memory +800/Core+160/voltage+25: crash

Memory +1000/Core+160/voltage+25: 14547 maxtemp:57C

Lost a few pts, going back to 1100 men to see if I can reproduce previous value.

Memory +1100/Core+160/voltage+100: 14578 maxtemp:58C
 
no change in results with higher voltage

This thread is great, thanks. Is your fan curve default or custom?

I use default fan curve. 

If you're savvy enough, you might want to flash the 3090 XC3 VBIOS and see what you can get. It will run hotter, but for benchmarking it really opens up the 3090 FTW3. Be sure to back up your current VBIOS.

Here's my best (on air) 3090 FTW3 Ultra on the XC3 Ultra VBIOS run vs my very best XOC (which was the same performance as the stock OC VBIOS):

I am tempted to give that a try. I wonder if I could break 15k or at least get close. 

Generally, most of the Evga cards seem to hit +180 reliably. Some hit 195 and 210. And a smaller amount hit 225. But, those higher numbers aren't necessarily producing higher scores.

3090 FTW3 Ultra (NOT HYBRID) ..adding for comparison.
Memory +1000, GPU +150, Port Royal 14,100 - and that seems to be as good as I'm going to get on air on this card.

These cards seem to have a heavy thermal throttle.
 

Adding as comparison as well.
3090 FTW3 Ultra (Not Hybrid)
Memory +1000, Clock +205 , Voltage +100, Did not update the XOC Bios Beta for more voltage.
Port Royal 14442
Ran on air only inside a Lian Li O11D


Must have been a fluke for that run because I was never able to hit +205 clock again

Had stable runs with mem +1000, clock +195

Good hunting on your benchmarks!

Not a fluke. These cards seem inconsistent in general. But in this case, it is most likely changes in ambient temperatures affecting the entire system. A nice drop in temperature with an open door in the winter can push scores up a bit.

I wish I could even come close to that score and what are your card clocks. I can't get any higher than 14,300+.

Is that with the XC3 VBIOS on your 3090FTW3? My best with the stock OC VBIOS or XOC VBIOS was 14233 and took a very long time to get. Thr XC3 run got me 14800+ after a minimal amount of tweaking. My card shows power limits like mad from 400W to 450W with the stock OC or XOC VBIOS. The XC3 VBIOS still shows power as a limit, but it pulls a LOT more from the wall - like 60 more watts. GPU-Z won't read the third power plug, and the power readings won't be right, and the fans can act really wonky when you set them to 100% during benchmark runs (they sound like they are dropping to 75% or lower at times before ramping back up) - but the score increase happens because the card doesn't downclock heavily. It seems more in line with a thermal bin reduction instead of power / voltage.

I have the FTW3 Ultra XOC bios. I have seen in some games hitting 480+ power like Shadow of the Tomb Raider. Max temp averages around 62C during the benchmark.
