I am waiting on my EVGA FTW # Ultra 3080 Ti to arrive on Monday. my current system has a 750 watt psu... running 11700k @ 5.0 1.42v 2 NVME ssd drives 1 HDD drive 2 sticks ddr4 ram 3600 mgz Gigabyte z590 Aurous elite ax mobo 360 AIO cooler 3 case fans including 3 more on rad i have a 3080 in it now but will i be ok with the tripple pcie wires needed for that wattage card with a 750 watt psu?
Hmm I can have 1920MHz 925mV and +1000 DDR6X and i know it's way too fast for my needs. -> https://twitter.com/GraphicallyChal/status/1510689061140254723?s=20&t=b_0Vbfx7SStgZeTn-i2paQ
MSI 3080ti suprim X now... Edited curve with Afterburner to avoid constant variable frequencies, need less power. Duplicated curve for profiles then just changed power setting (70-85-100%) 1755MHz 793mV 1800MHz 825mV 1860MHz 850mV 1905MHz 875mV 1935MHz 900mV 1980MHz 925mV
My highest firestrike until now. https://www.3dmark.com/3dm/74496608 Score: 40472 - pure Bios OC, no tools. Ftw3 Ultra 3080ti and ryzen 5900x.
Starting to think my card isn't that bad after all. I have tested 1950 @ 875mv but have bumped it up to 1950 @ 893mv to be safe. (Touch wood) I've not had any issues running 1950 @ 893mv, +350 on the VRAM.
The card has a feeble 105% power limit. Even then, GPUZ never shows much over 350W board power. So 2ghz isn't possible. To stay under the power limit, the GPU needs to be at less than .9v. Sure it will boost to over 2ghz occasionally but not when the GPU is under proper load.
This got me wondering. Why does my card seem to use 350W max, even when I set the slider to 105%? Most of the time GPUZ is reporting ~95% TDP but PerfCap is Pwr. Is this normal or is there something wrong with this card?
That's nothing, I have a 3080 12Gb Gaming Z Trio, playing at 4K with ray tracing/max details it regularly hits it's max 390w power limit and has to downclock. It's 3 x 8 pin and MSI allow 102% in afterburner lol. I mean it's a great card, very quiet and cool but wow. I just set to 1800 low voltage and lower some details, the clock variation does my head in. Also, no major difference from max power to that undervolt in terms of framerate, only seems to lose 3-4 fps max Don't know anything about bios modding,don't even know if its possible on this card but a 450w bios from MSI would have been nice.
if you only have two 8 pin connectors then it is normal for it to only use 350 watts max as it seems nvidia limits the pcie usage to 50 watts. I think this only only happens on pcie 3.0 boards though and the driver allows higher usage on the pcie 4.0 slot. I have the same issue with my Asus Tuf 3080 ti and the only people that can get this card to go over 350 watts all have pcie 4.0 boards.
I only have a PCIe 3 slot and this 3080 12gb easily hits the full 390w power limit so is this only a Ti issue?
please read the FIRST sentence of what you quoted. you have three pci-e connectors on your 3080 not two so you can get all the power you need through the connectors.
