Yesterday someone in this server helped m and told me that the 7800x3d is the best GAMING cpu. So i told my dad that i wanna switch out the originally planned i7 14700kf with the 7800x3d. He said yes but that when he built his old gaming pc long ago that AMD cpu's werent stable with rtx graphics cards in his experience. I just wanna know if thats changed now.

So many say oh the system they just got is unstable I say its mosty motherboard auto oc a bit and xmp also a bad oc thats unstable there not any instblity form amd cpu and nivda gpu

plain veldt
untold sparrow
#

Just get jedec ram and disable any auto oc mother board has

plain veldt
#

whats jedec ram?

#

im getting g skill

untold sparrow
#

The ram spec

plain veldt
#

ddr5 6400mhz

untold sparrow
#

Like 4800 cl40 1.1V

plain veldt
#

32gb

untold sparrow
#

And ddr5 6000 cl48 1.1V

plain veldt
#

no clue what cl48 1.1v means

untold sparrow
#

And ddr5 5600 cl46 1.1V and it will not say xmp

#

On pc part picked set the voltage of ram to only 1.1V and pick one I tell you if its jedec

plain veldt
#

there is 1 option

untold sparrow
#

This jeddc

plain veldt
#

yh that one

untold sparrow
#

And many other ones

plain veldt
#

so i need those?

untold sparrow
#

Those are way more likly to be stable them any xmp

plain veldt
#

so this wouldnt work?

untold sparrow
#

Don't spend that much on cpu cooler

#

Ram you picked I give 20% chance of working

#

Just due to speed and being xmp

#

Other then that's its down to prices and brand prefince

plain veldt
untold sparrow
#

No dont get that ram or be prepared to manual oc the ram

#

Past 6000 with amd and Intel ram start to get more and more likely to not work amd needs like top 1%to run 6600 and 6400 is like most cant but nothing special if it can 6200 most can but no guarantee then getting to 5200 will work

#

And jedec will run at fastest supports speed with out needed to mess with any settings

plain veldt
#

my build can't run 6400mhz ram?

untold sparrow
#

Unlikely to

plain veldt
#

how, its basically top of the line no?

untold sparrow
#

Amd 7000 cpu cant do any higher then 6000 reliably but just get jedec

plain veldt
#

ohhh, is there any better amd cpu i should go for then?

#

like a ryzen 9

untold sparrow
#

Intel clames 8000 works on 14 gen but that's a lie

plain veldt
#

but i dont need 8000

#

6400

untold sparrow
#

Why do you care about ram speed so much

plain veldt
#

idk

#

i like top of the line for future proofing

untold sparrow
#

And all 7000 cpu have the same imc so they all do ram the same

#

But x3d cpu care less about ram do to having way more l3

untold sparrow
#

And ram speed is not the thing that make ram perfomice faster or slower

#

It's the relation of timing and speed and cpu imc setting like uclk=mclk or Uclk/2=mclk

plain veldt
#

ah okay

untold sparrow
#

And the timing listed like 40 40 40 120 those are the not important ones but that are only ones to get listed due to they where important for DDR the first gen of ddr

#

But are not any more for ddr5

plain veldt
#

would the corsair dominator work?

#

titanium

#

its 6000mhz

#

cas 30

untold sparrow
#

Just get jedec

#

Like the one listed

#

That's works and has good IC if you want to manual oc latter

plain veldt
#

okay

#

Dear God I almost had a stroke reading this

#

@untold sparrow bro I think you are just confusing him more

#

@plain veldt just get 6000mhz ram as 6400 MHz may not work as well and won't be much better for performance

#

And CL timing are more important then speed for ddr5 on and cpu even more so for x3d chips they don't benefit from the extra speed

#

Don't get anything higher then CL 36 trying get CL 30 ram

#

And no there no know stability problems with rtx gpu and amd CPU

#

I say just go with the 7800x3d much faster than the i7 for gaming and more upgradeable for future proofing because of am5

ruby zenith
#

It likely from something else like a bad overclock

untold sparrow
#

i take ram with higher tcl if it more mhz any day

#

and fun thing is threre the same tcl if you think about it

ruby zenith
untold sparrow
ruby zenith
#

Yes

#

But higher CL timing

untold sparrow
#

its the same cas

#

10ns for both

ruby zenith
untold sparrow
#

and that dose not even matter much since tcl has littel inpact with newer gen of ram

ruby zenith
#

Dd3 has less time in ns

#

It's like 4ns

untold sparrow
#

but ddr3 stalls out way more

ruby zenith
untold sparrow
#

how is 6000 any difnret

#

i have not had xmp ever worl form me

#

ddr3 ddr4 5 systems more ram kits and its peroimce is bad

ruby zenith
untold sparrow
ruby zenith
#

Well

#

More like 5200 MHz

untold sparrow
#

imc on amd maxes out about 3200mhz then to get higher ram speed you need to enter uclk/2=mclk

untold sparrow
ruby zenith
#

Bro

#

Ryzen 7000

untold sparrow
#

yes thats what we be speaking about

ruby zenith
#

Also please stop using so much technical jargen

untold sparrow
#

i am not ram is just pain

#

and i have seen board run imc at 1500mhz at ddr5 6000

#

even for auto that sucks

ruby zenith
#

And xpo

untold sparrow
#

xpo?

#

expo is just xmp but new name that amd made up

ruby zenith
#

Expo

#

Ik

#

Still

#

Anyways

ruby zenith
#

Man

#

You are not good at explaining things

#

You know what they are

#

But you assume people know what you are talking about

#

Please don't do this people just end up more confused

placid quartz
#

Well computers are technical, and these are specs.

ruby zenith
#

Ik

#

But you can explain it

placid quartz
#

Fmr my 7800x3D I got 6000 mhz cl 30.

ruby zenith
#

Don't assume people know what you are talking about is all I want to say

placid quartz
ruby zenith
ruby zenith
#

Even if the cpu only consumes 75 watts

placid quartz
#

sure. I'm also guilty of extravances 😄
