Upgraded from a xfx 590 to a powercolor rx 6900 xt which was a good leap in terms of performance. Recently I downloaded The Finals and was getting very poor performance [30 fps] tried making changes and updating drivers nothing changed, ran into some weird computer problems dot being connected to my network but still having internet and ended up doing a full computer reset and installing wondows 11 (was running 10) which fixed all the problems not involving the gpu. Started The Finals and was able to get around 60 FPS. Still a new game so I went to check Apex Legends which I would usually get anywhere from 120 to 144 and after looking at 6900 benchmarks saying they would get 196 FPS I was hoping to get close the that but after messing with multiple settings I was still only at 144 but would drop to 90 when actually playing and consistently bounced around.

I enabled XMP but ram is still only at 2133 mhz. Any help would be much appreciated been dealing with this for a week now.
Running a 144hz monitor at 2560x1440

What is the XMP profile speed of your RAM? What is your screen resolution? At 1080p your 2700X will be limiting factor that will cause your RX 6900 XT to suffer quite a bit. Should it be dropping to 30fps?? Probably not, although I'm not familiar with that game. At 1440p it would be less of a limitation, but still present.

Screen resolution is 2560x1440 and the xmp modes are I believe 3200mhz and something like 2950 mhz I tried both settings and it never went above 2133 while doing anything
Using 4 8gb ddr4 3200mhz sticks

The 2700x is going to be the limitation right now. Also, the RAM situation isn't helping at all.

Use only 2 matched RAM modules in slots a2-b2. Enable XMP in BIOS.

Also, what PSU do you have?

removed two sticks of RAM and now running more stable 151 fps in Apex Legends still would have thought I could get higher with this GPU. PSU is a 750W corsair not the highest, but I've never seen much of a draw on any of the metrics while playing.

Sounds like your 4 sticks of RAM didn't like to run together in XMP.

Your CPU is what dictates the total fps possible. You could install a 4090 and it wouldn't increase.
 
That CPU will hold back your DRAM speeds even under the best of circumstances. Trying to run 4 DIMMs with it is just asking for trouble and is likely unusable at the speeds you were trying.

If you still think you're not getting as much performance as you could then I'd suggest running 3DMark just to be able to compare directly to other systems with the same GPU/CPU combo.
 
I agree the 2700x was not bad in it's time, but with a 6900xt, sell the 2700x and get at least a 5700x.

I listen to this guy on youtube sometimes and he makes a lot of sense. He had someone recently ask him a question recently where the person had a 2700x and an rtx 3070 and was getting bottlenecked by their cpu. So you can only imagine what's happening with the 6900xt. No brainer 5700x.
