Zotac 3090 seems slow

SarahWild · 10 Oct 2020 at 18:18

Hey all,

Does anyone else feel the 3090 is slow? I have 64gb RAM, 3900X, 2560x1440 and in metro everything on extreme I get a whole 60-80 FPS.

In 3D mark I am getting
12452 in Port Royal
and
17526 in Time Spy.

I came from a 1080 FE.

The card is boosting with stock settings to 1900mhz +

any feedback would be appreciated .

Up the resolution with DSR to 4k and see what you get.

13999 in Port Royal here with a shoddy old 7700k.

You have an AMD processor though. Drop a 5900X in there

I'm going 5900X as soon as they launch got a board and ram sat here waiting!

Windows power management is shocking.

You can set affinity and power plans any way you want, I use process lasso to automate this. This gets the most out of any game/program accordingly.
If you don't have AMD's chipset drivers, these have the Ryzen Performance profile.

Works wonders. This is assuming this hasn't been done already and the card is actually okay.

my guess

crap windows bloat
slow ram (3200 or lower) / high timings
low resolution
CPU to hot to Boost
metro is quite cpu heavy
extreme is ridiculous settings (like 8xAA MSAA)

I am on 2666 mhz ram, as I have 4 sticks of 3200, so I am using Jdec default instead of xmp. I should have a play with the ram to get it higher.

The ideal for the 3900x is 3600mhz as the infinity fabric runs at 1800mhz by default.

Running slower Memory will create more latency at a cpu level and lower frame rates.

you really need to run 3200+
I have a 2950x with 4 sticks (32GB) running 2666mhz vs 3200 is huge drop in perf

3900X bottlenecks the 3080 at 1440p in some game. Will be even worse for the 3090.

Metro Exodus is one of the worst affected.

What you need is a Zen 3 chip.

^^ that's why I'm swapping the 3950x for a 5950x

Agree with this, except I'd doubt RAM at 3200 would hold him back much.

Seriously, people are thinking a 3900x is a bottle neck?? Heard it all now

SarahWild · 10 Oct 2020 at 21:25

I will take 2 sticks out and slap them back in when I need to crunch some data

3900x in some games are limiting the FPS even on my zotac 3080 trinity oc not by much but my intel based pc friends are slightly ahead of me in a few games at 1440p wouldn’t say it’s a bottleneck but defo some noticeable difference

For games that crave single core performance, yeah seriously!

why just run them at 3200? & test? 4 sticks at 3200 on 3000s series should be easy. i managed it on a 2950 and they was known to have dodgy IMC

Yup, Zen2 isn't really much of a gaming cpu more of an all-rounder I'm afraid.

SarahWild · 11 Oct 2020 at 03:00

When I pay off the £1000 left I have on this card I will see about getting a 5000 series perhaps. In the mean time I will try 3200hz by changing the timings, unstable on 16 18 18 18 36 1.35v. I have Ryzen DRAM calc to aid me.

Biggest tip is ignore most of the posts on this forum since they generally have no idea what they are talking about

Rroff · 11 Oct 2020 at 03:51

People are right about the RAM - you will see a fair performance penalty below ~3000-3200MHz depending on the Ryzen CPU and a small but noticeable benefit up to around 3600MHz.

First thing you should do though is eliminate issues such as OS bloat i.e. make sure nothing is running in the background using a lot of CPU or IO resources, make sure temperatures are as they should be, etc.
