Worth the Upgrade? DDR5 6800 CL32 to DDR5 7200 or 7600 (OC to 7600 - 8000) ?

I'm considering upgrading my memory to the new 7000+ DDR5 kits and I'm curious if it's worth it for gaming?

I'm currently running DDR5 6400 @ 6800 CL32 on my MSI Z690 Unify-X (2 DIMM Board) with a 13900K.
I was considering a 7200 kit (shoot for 7600) around $300 or a 7600 kit (shoot for 8000) around $375 .

Do you think there's a benefit or value in making this upgrade since I game at 4k / 144hz?

Thanks
 
Higher RAM speed helps CPU performance.
Resolution has virtual no impact on CPU performance just GPU except for some older game engines.
So if you are playing a very CPU heavy game that makes GPU usage drop when you get low FPS dips then faster RAM may help.
But just buying a faster kit wont do much as you already have a fast kit.

As frequency increases the timings go out the window (Except tCL but it doesn't matter anyway) so most the performance that would be gained by the higher frequency is lost.
As such just buying a 7600\8000 kit will likely get you ~1% more performance in a game that is RAM speed sensitive if it is CPU limited not GPU.

However if you take the time to learn how to OC your current kit of RAM and tune the sub timings you could see FPS increase by 10-20% in some RAM sensitive games if you are CPU limited. If GPU limited you will see no improvement from faster CPU\RAM.

Seems I was wrong.
6400-7200 is seeing up to 11% increase in CPU performance here.

I cant help but wonder if your 6400 kit could OC to 7200+ though.
 
I just bought G.Skill 6400 CL32 and I'm running it at 7466 CL36 stable. It is Hynix A-die which is the new good DDR5 for high overclocking. You may be able to get more out of your existing sticks.
 
As long as you sell me your old kit at a great price I guarantee you will get 600 FPS in all games at 8K. I agree you should try to oc the memory before buying new.

Just out of curiosity what is your CPU and Motherboard? Because at those speeds you're probably pushing diminishing returns to the maximum. You should be looking at what speeds you can get your RAM to run at 1:1 Fabric Speeds instead of 1:2 or Higher divisors. You will (almost always) get more out of 1:1 then you will out of lower Fabric/Gear memory divisors.

1:1 does help an itty bit if you only want to overclock up to 6400.

Above that 1:1 gets wonky real quick and can be beaten with good manual timings.

There are people with 8000 xmp kits that boast stability and run a latency of 54ns.

So what should i think having set my 6000 cl30 kit to 7200/cl34 and my latency is 52.5?

So to the orginal Question: Hell No! You have already a stable and good enough setup.

Why waste so much money for 4-8 frames?
 
I've been thinking about this also for a while. I have a Gskill hynix 64gb 6000 C32 kit that I run at 6400 at 1.45v or can do 5600 at 1.25v. I've considered getting a faster set set like over 7000 but I always come to the realization that it just isn't worth it. Especially because I have a 64gb kit and there isn't anything faster in this capacity so 6400 C32 is plenty fast and I can even OC it further to 6600.

Nice board. The use case for faster RAM is highly dependent upon the applications you are running. Some apps are more bandwidth sensitive than others and others care more for lower latency memory. What you need to be looking at is what the actual gains you're getting are as you ramp up frequency. It's possible you can even lose performance.
