Power Limit problems with my Gainward RTX 3080

[Rom]

320w is not enough for these cards. Based on my 3080 FTW Ultra, im running the 450W bios, pulling the full 450W, and I still get PWR perfcap in benchmarks!
Mine will boost to 2145 max so far. Temp wise, Ive seen mine hit 72, and still boost to 2070 in benchmarks.

So while the posts are correct, temps will limit boost, 75 shouldnt be knocking 150+ clock off.

If that is the best bios Gainward do, unless you want to flash another brands, which Ive read can be detected should the card brick with that bios in it, you are pretty much out of luck.
That seems very low, standard mine was pulling 400w. Even the 450w is not enough.

Looking at your card, it is only advertised as having 30mhz more boost than FE. They only 'guarantee' 1740.

The power slider is broken on some cards and you won't see above 100%.

GeForce RTX™ 3080 Phantom "GS" is the better card with 3x8-pin connectors. http://www.gainward.com/main/vgapro.php?id=1093&lang=en
GeForce RTX™ 3080 Phoenix "GS" has 2x8-pin connectors. http://www.gainward.com/main/vgapro.php?id=1087&lang=en

Each 8-pin connector is 150 watts and the PICe slot is 75 watts.
So the Phoenix GS is 350 watts, 300 watts via the two 8-pin connectors and 50 watts from the PCIe slot.
The Phantom GS has three 8-pin connectors for 450 watts total and 75 watts from the PCIe slot. So does the EVGA 3080 FTW Ultra.

Dont expect the same performance from the Phoenix GS at 350 watts as you would get from the 450 watt EVGA 3080 FTW Ultra.

The ASUS TUF RTX 3080 GAMING OC is 2x8-pin and is limited to 375 watts because thats really the maximum you should go.

GPU-z is showing that the card is at its power limit. 320 watts board power draw. Undervoltage helps because it reduces power draw. The PerfCap reason is PWR. So you need to increase the power limit. Also I noted that in GPU-z the GPU is hitting 75c. These cards are rated to 83c. The only way to get higher clocks is to go colder, as it reduces power draw.

All the cards hitting Boost Clocks of 1900MHz from the factory have 3x8-pin connectors.

The GIGABYTE AORUS RTX 3080 MASTER is one of the 2x8-pin cards that hits Boost Clock 1845 MHz and has a power limit of 370 watts. https://www.techpowerup.com/vgabios/225605/gigabyte-rtx3080-10240-201006

The MSI RTX 3080 10 GB BIOS (Gaming X Trio) has a power limit of 350 watts and a boost clock of 1815MHz. 2x8-pin

Apply a core overclock. It will then have higher clocks at the same voltage.

Maybe try something other than Afterburner if that is true.

I think it's a bug with the vbios where the 109% power slider doesn't actually do anything.

At the end of the day the difference in games from 320w to 400w would be around 2-5fps so your not really losing much as over 320w performance efficiency scaling goes out the window.

However if your more interested in benchmarking then get either the evga FTW3 ultra or rog strix OC as they have 450w bios available but you still want a water block on them to hit the big 20000k+ scores as more power = higher temps which also drop clocks.

Other RTX 3080's have the same issue, it's down to the quality of the VRMs as well, some FE cards draw 370w some other reference cards draw 350w, there's no way without flashing a vbios to your card to go above 320w TDP.

Just enjoy the card and stop chasing numbers.

Maybe a new bios correct this “problem”.

I wouldn't call it a problem as other than benchmark chasing it's hardly worth going over 320w anyway for everyday gaming as the FPS gains are minimal.

Agreed. It would give me anxiety if I had a card running at 470W continuously but then I am the kind of person that plays the MPG game when I drive somewhere.

I've got the GB gaming OC that will pull 370W but it's so much quieter running below 300W with an undervolt it's not worth cranking it up for the extra 3 FPS in games. Diminishing returns above 300 really seem to set in.
