Memory Speed for Ryzen

It really depends on how good the kit is but 2666MHz should be doable.

Alright, will the motherboard affect anything because I know there is a lot of motherboards that you do or do not buy.

Right now on Ryzen, definitely. You will need to do some research. I don't have much experience with the AM4 boards.

honestly i would say that it is hard to even achieve the ram speed that is advertised on a kit for ryzen so i think that telling someone it is easy to overclock ram on ryzen  is being dishonest.

The XMP profiles don't work correctly, you have to dial in the settings manually most of the time.

The OC process is simple.

yes but that is with ram that is rated for that high of speeds. even then it doesn't always work so telling them they can do it with ram meant to run at lower frequencies is kinda misleading. Do you have any experience with overclocking on Ryzen? because i do and i would argue that what you are saying is quite misleading.

I still don't understand what you mean exactly. Rated speeds are 2133MHz and 2400MHz, anything above that is OC profile that is not guaranteed to run even if the kit itself claims 3200MHz+.

On Intel it works almost always because XMP kits are optimized to run on Intel, usually only the high frequency 3600MHz+ don't run without playing with IMC voltages, etc...

On Ryzen most kits were stuck at 2666MHz-2933MHz because of bad BIOS, which is fixed on most motherboards now (not all). That's why I said to OP to do some research about this as I know only few boards that have this fixed and those are expensive boards.

if they are rated to run at a certain speed there has been some testing involved to make sure that they can reach those speeds otherwise why would anyone even buy them. all i am saying is that you telling them that they can reach 2933 with a 2400mhz kit when others are having trouble with reaching 2933 with kit a marketed speed of 3200mhz. you can get into semantics all you want about what they mean when they advertise a higher speed kit but bottom line is they are tested and are supposed to be able to reach those speeds while the lower speed kits are only tested for their respective speeds.

"On DDR4 the 2933MHz should be achievable with good enough timings on most 2400MHz kits." here is the quote of what i was saying is super misleading and I have a problem with. i would just like to make sure op isn't being mislead by your comments. I'm sure you are only trying to help but i would say what you are saying is way to optimistic.

The kit can achieve the speed it is rated for. If the IMC in CPU is not strong enough then you will not achieve the speeds....

If the BIOS has some fault in it, it can be more difficult or impossible to achieve the rated speeds...

The factor is not just the RAM kit. And this is not just Ryzen thing, you have to consider these things on Intel as well.

Remember when reviewers claimed that Haswell has difficulty to go above 2133MHz?

Well, it requires user to increase memory controller voltage, then you can sky rocket the frequencies.

It is not unreasonable to expect average 2400MHz DDR4 kit to achieve 2933MHz. Of course, it is overclocking and nothing is guaranteed.

That is not being misleading, that's the same thing as saying that most 7700k should be able to achieve 4.6GHz... because most of them really do.

saying that when you are talking about ryzen is super misleading. you take 10 2400mhz ram kits and oc them to 2933mhz on ryzen and see how many you are able to oc to that speed successfully. as someone with actual experience trying to get memory rated at 3000mhz to run at 2933mhz speed on ryzen it is not as easy as you make it seem. all i am saying is that as someone with experience with ryzen and trying to get the memory to run at 2933mhz i would never tell someone that they would most likely be able to get a 2400mhz kit to run at 2933mhz on ryzen. I am just trying to look out for op because if someone told me that i then i had my experience with ryzen memory that i have had i would be really mad. someone making it sound easy and that most kits would be able to do it then i find out it is quite hard and takes alot of work and the likeliness of it working isn't all that high.

also don't go putting in these types of caveats in your statements way after where they are said. that is the definition of misleading. either tell them with your original statement or don't say your original statement.

Ryzen has memory controller capable of achieving memory speeds greater than 3200MHz+

The problem lies in the AM4 motherboards mainly in BIOS.

 

I said it twice already, now I will say it third time.

I know only few expensive boards that have good BIOS on which most supported RAM kits are able to achieve high speeds.

Please, OP do your own research.

In gaming it does.

^{I think we're both arguing the same thing}

I was responding to OP asking if it affects video rendering so yes, I think we're arguing the same thing
