Mines up and running undervolted to 1010 and left everything else at stock, I have a 1080 ultra wide so no need to push further. Staying cool and quiet and I have the extra in the bag for when I get a 144hz screen.

Also is anything on the GPU suppose to light up, RGB etc? Because nothing is lighting up.


No riser.

Cable was fine on previous GPU.

Occasionally can be a failing capacitor/psu issue. Mine was crashing on load on a RM850x until I swapped it out for a RM750x I had lying around. Now no issues for last 3 months.

OC that to 4080 stock level! Saving yourself £500 in process!

Yeah I'm going to need some advice on setup. I'm slightly bothered about heat so don't want to overclock it to death. But a slight undervolt plus maybe a few extra clocks would be nice if anyone can advise?
 
GPU arrived, installed and working great, surprisingly quiet until you really crank up the settings in Cyberpunk at 1440p RT High the fan was audible but to offset that I just cranked up the speakers :)

Benchmark had me pegged at 60fps which I am more than happy with. D4 at Ultra 1440p is basically monitor cap of 144fps.
 
It’s going to be a lottery but I benched my 7900 XT down to 1000mV with max 3000 core clocks and 2750 VRAM with +15 power slider. It gave an increase of 11% on the GPU score but power consumption was 350w

I found that you don’t get reduced power draw by reducing the voltage, that just results in higher core clocks due to better power headroom. So set lower voltage AND set a reduced power slider to ensure lower power usage.

Even setting -10% power slider at 1000mV gave just under stock speeds but lower power draw at 290w max. So similar power/perf to a 4070Ti. Though of course the 4070Ti will undervolt as well but the performance will drop as well.

I think I got lucky in the silicone lottery but too early to tell. Going to leave it at stock core and vram and 1050mV. This generally gives about 5% extra performance at the same 320w consumption.

With OC settings it is giving similar GPU scores as my 4080 using 3DMark. As long as it isn’t RT ;)

Tempted to get the 7900 XT but been reading about high idle power draws with multi-monitor setups (currently using ROG PG279Q and LG C2 42"). Would I be affected?
 
You can undervolt on RDNA3 by just lowering the clock speed due to the voltage frequency curve. Yes you can also reduce voltage, but there is a chance you will introduce instability if you do so.

Monitor voltages at default settings, just change the core clock frequency between 3000Mhz and then 2000Mhz. 2000Mhz will see much lower voltage, power draw and temperature and will be stable if you leave the voltage alone.

Reducing voltage can be handy if you want to run a higher clock speed (say 2.9-3Ghz) and are hitting the power limit. In that scenario lowering voltage can help increase the core clock speed by reducing the power drawn.

I'm getting ~40w idle with a 34" 1440p ultrawide and a bog standard 1080p 24" monitor. A few watts higher than my previous GPU the 5700XT.

Not bad! i do wanna see if anyone else has a similar setup with 3 monitors, single ultrawide plus 2x 27" monitors to see what the idle draw is.

My 3090 has a weird glitch (pretty sure its nvidias drivers) where setting all the monitors to the same response rate makes the power draw idle around 100w! Only fix i've found so far is to drop some of the monitors down to 60hz and i can idle around 28-32w.

@LtMatt Ok, so on top of my earlier sound issues, I've just tried firing up RDR2 on my TV to test and I'm getting a lot of artifacts (like the white/magenta snow sort)....
I've checked the HDMI cable I'm using and the listing said it is rated for 18gbps - Is this likely to be the cause of the issues?
I could deal with the idea of running the audio over SPDIF, but if I can't play games on the TV then there's very little point in me keeping the card :(

(edit: I played ARK for a bit on my other monitor and it seemed fine, so I don't think the card in itself is broken)
