So I ordered a ryzen 7700X and ram. I ordered 32gb of G.skill Trident z5 7200 ram, but I realized it doesn't have AMD expo, only the z5 NEO has AMD Expo. Is this a necessity, like should I cancel the order and get the z5 neo? Or will it be fine as is?

you aint running 7200mt ram on ryzen 7000
that ram will not work
get something like this instead
sudden mauve
you aint running 7200mt ram on ryzen 7000
What exactly is AMD Expo though? Like can I not just run the 7200 ram at whatever speed the CPU can handle? Genuinely curious
haughty mulch

ryzen 7000 cpus can handle 6400 most of the time
If you go higher you’ll probably have to configure it manually
And there isn’t really any performance benefit
Every cpu can run 6000
sudden mauve
If you go higher you’ll probably have to configure it manually
So it would post, I'd just have to manually set the speed?
haughty mulch
Yes
If you’re willing to spend a few hours tuning stuff
You could get it running very well probably
sudden mauve
But what's the difference between AMD expo and not having it? That it would automatically tune it for me?
haughty mulch

It’s just amd’s version of xmp
And yeah it’s automatic overclocking
Both xmp and expo work on amd
haughty mulch
Oh wait XMP works on and too? I think that ram has XMP 3.0
Yeah
But it prob won’t run
You might have to run the memory controller & infinity fabric slower than the ram or smth
sudden mauve
But it prob won’t run
Why not?
sudden mauve

I'm going to be honest, I do not understand what that means
haughty mulch
Why not?
AMD has a worse memory controller than intel
So it can’t run ram at the same speeds
Intel cpus can manage 7200mt just fine
If you want it to work out of the box get a 6000mt kit
sudden mauve
Ohhhhh okay. So it wouldn't be able to run at 7200 even though the Ram can. But I wouldn't even be able to run the ram at a lower clock speed even with the XMP?
haughty mulch
Ohhhhh okay. So it wouldn't be able to run at 7200 even though the Ram can. But ...
You would
You would just have to tune a bunch of stuff manually
sudden mauve
You would just have to tune a bunch of stuff manually
I couldn't just lower the memory speed to 6000? Is that no an option?
haughty mulch
You can also try running the ram at a higher speed, and desyncing the memory controller and running it at half the speed
haughty mulch
I couldn't just lower the memory speed to 6000? Is that no an option?
Yes
You can
But you’ll have to manually set all the timings
iirc
sudden mauve
But you’ll have to manually set all the timings
What does that entail? Like tbh I'm usually okay with messing with PC setting and I like the look of the RAM so I'm willing to mess with the timings if it's not too overly complicated.
But obviously if I think it's really difficult I'll return the ram and get different ones that would work better but if I can avoid that and make what I got work, then I'd rather do that and if I upgrade in the future to intel/amd can use faster ram then I'd already have ram that can handle it
faint owl
you can lower the speed manually BUT then you might aswell return the ram get cheaper ram so you wont waste the money on the fast ram and actual 6000 ram will be more stable than manual 6000
that is what you want instead

Suboptimal timings

These ones are $20 cheaper with better timings https://pcpartpicker.com/products/compare/H9CZxr,PxTZxr,HNZXsY

But you’ll have to manually set all the timings
or just downclock the frequency lol
its not that hard
haughty mulch
or just downclock the frequency lol
It might keep the timings higher
small pendant
theres different options
faint owl
or just downclock the frequency lol
it would keep the higher timeings
small pendant
of xmp
faint owl
so you would have to majorly downclock the voltage
faint owl
theres different options
yes which is too manually do all the timings lol
small pendant
just primary ones, leave the rest on auto lmao
faint owl
just primary ones, leave the rest on auto lmao
you never should do just some and leave the rest
thats a terrible idea
small pendant
it goes on auto
haughty mulch
just primary ones, leave the rest on auto lmao
💀
small pendant
primary timings are what u see on the listing, like 3600c16 16 16 36
faint owl
yes once you do one manual you CAN NOT do the rest on auto
haughty mulch
Yeah my secondaries are on auto and they’re shit
I need to tune them when I have time
small pendant
yeah well xmp is a lot worse than custom
faint owl
primary timings are what u see on the listing, like 3600c16 16 16 36
thats not what auto would do what auto will do is set the memory to its JEDEC
small pendant
its actually better because it will be alot more stable
or just test custom timings to make sure theyre stable
thats like pretty obvious
faint owl
still xmp/expo is better for the rams lifespan
faint owl
thats not what auto would do what auto will do is set the memory to its JEDEC
and as i said here you need to do all the timings manual once you do one any auto ram timings will defualt to the JEDEC witch could cause problems
sudden mauve
What are ram timings
Like I get clock speed but what are timings? And why does that matter? And why is it different between different ram sticks
And what would happen if I plug the 7200 sticks in and don't touch anything
faint owl
And what would happen if I plug the 7200 sticks in and don't touch anything
then they would run at JEDEC ddr5 speeds
which iirc is 4800
sudden mauve
which iirc is 4800
Oh ew
sudden mauve
now i reccomend returning that ram and gettings some 6000 cl 30
Okay, ill prolly end up doing that. But how does one like create their own timings, like I would have to if I kept the 7200 ram?
faint owl
bios
which will take a very long time
why would you want to keep the expensive ram just to use it at alot cheaper ram speeds
sudden mauve
which will take a very long time
Okay so yeah prolly not for me then
sudden mauve
why would you want to keep the expensive ram just to use it at alot cheaper ram ...
So what ram timings are good I'm looking at ram on PC part picker, 6000mhz, and I want white RGB ram because that goes with my aesthetic, but there's still a lot of options
faint owl

cl 30
but timings barly matter
sudden mauve
Do the rest matter?
faint owl
Do the rest matter?
yes
sudden mauve
Which of these is good?
faint owl
30-36-36-76 or 96
sudden mauve
30-36-36-76 or 96
Thank you! I. Looking at teamGroup t-force delta RGB ddr5 6000 cL30. It's amd expo compatible
It's timings are 30 36 36 76
