The Ampere RTX 3090 Owners Thread

Mine is OK at 875mv, 1935mhz. Memory is so hot though I actually downclock it! That's a gigabyte 3090 vision oc though.

Thank you all.

Is 3dmark still a usefull tool to run to show performance?

The Port Royal stress test gives the card a very good run for its money. I think it's 20 cycles. I find it runs the GPU at 100% and is better at maxing out the W draw of the card.
If you wanted to go for more system stability then run Cinebench (can't remember if it's 20 or 23 that runs 10mins) at the same time.

That will also give you a good idea how good your case cooling is.

Obviously that is only a synthetic test, and not quite the same as real life use, for better or worse.
I would stay away from programs like furnark/kombuster etc as they are known to test at the extreme.

If you have games that don't max out the GPU, you could try using DSR to increase the resolution to make your GPU work harder. This is also a good way of getting better visuals at lower monitor resolutions if you have performance to spare. And there are plenty of games the 3090 can do that with, running at 4K on a 1440 monitor for example.

I do this with my 4090, as that has plenty of headroom in a lot of titles.

Agreed. I would pass synthetics but crash in RDR2.

Just wish the memory thermal pads weren't so bad on the aftermarket models...
 
Apologies for "hijacking" the thread, but it might provide a useful discussion for people joining the 3090 party later in life.

So, i've done some testing. This is what happened at stock. Not hitting very high numbers?



So then I did this after following the above guide:




Results were identical:



Some temp numbers (max is what's important?):




I then upped the temp and power limit:



And got this result, better!?:



Some temp numbers (max is what's important?):




I'm still only getting 1930 despite my curve being set to 1950. Is that right?

And finally....is this noise coil whine? it only happens when the benchmark is running, can it be resolved?

Nvidia Boost tech is very clever, it allows you to tweak how you would like to run an Nvidia GPU, while it operates in the background looking after all aspects of the card, and will override your settings to look after the GPU etc.

Obviously there are limits set, and also the silicone lottery that Nvidia Boost tech adapts to also.

I suppose what I'm saying is: What do you want from your GPU? Flat out performance, noisy fans, chasing numbers etc..Or something else you are happy with, be it clock speed, memory speed, fan speed, temperature, power draw, noise, lifespan etc..

In the end, I ran my 3090 with a custom fan curve, to keep the fans quiet, I didn't overclock the memory, and I ran a small under volt on the core. All this kept the performance around 1900mhz (if I remember rightly) while keeping things cool at an acceptable fan level. Core got to around 65, and memory junction high 80's.

As most of the reviewers report nowadays, overclocking isn't really the performance boost in real life that it used to be. So I wouldn't worry about missing out if one card doesn't do the same as another.. As 99% of the performance will still be there.

Have fun :)
 
I use to run an overclock on mine but in all honesty its just better to bang the power limit up and let the card do its thing. Will happily sit around 1980mhz to 2035mhz depending on the game usually. Cards on water so it tends to clock abit higher but nothing mind blowing. It's a palit gamingpro card which has been rock solid for coming upto 3 years in September!

Is £465 used a good price for this? someone is selling one who lives near me,but I'm unsure as I read a lot of stuff about the vram getting really hot
Click to expand...

Yes a good price as they easily sell for £650 and up.

Even if it is the FE model from nvidia that has the so called heat issue on vram it is a good price as the heat issue only affected people mining on them in reality not using them for normal use, so go grab it before your friend sticks it up for sale elsewhere and he would even get more going to the local computer exchange place in the highstreet, also as the person is your friend i'm sure they can help you with warranty issues too and should be a more trusted person to buy from too.

They're not my friend but they live in my area and it still has just over 13 months warranty left.They have taken it down from sale,and I'm going to his house tomorrow to test it on his PC,so hopefully everything's good
