raMMM!!!

[cachowww]

guys alright, so apparently I just learnt that there are some types ram sticks that work better for intel and some types of sticks that work better with amd (I think they're Samsung B die?) however I have NO clue how to figure out if I'm buying b die ram sticks or not. any way I could find out? I heard you could in the serial/part number or in the timings but I have no clue which is which. help needed!!!

This sounds very interesting due to the AMD CPU RAM compatibility.

A rule of thumb is to look at timing sets.

Generally B-Die will run tight and even.

So 3600mhz sticks cl16-16-16 would likely be b-die.

If you see timings like cl16-18-18 or 18-22-22.... Those sticks are not b-die and probably wont play nice with Ryzen.

do you know which ram sticks would be b die for 3200 mhz?

also would b die ram matter much on the Ryzen 5 3600?

Generally G.Skill CL 14 are 3200mhz B-Die

It would depend on expectations.

B-Die is proven to be the most flexible cross-platform memory to use with either AMD or Intel.

Most 3600mhz sticks will overclock to 3800mhz stable and scale well with voltage increase.

but would it affect my system heavily if I do/don't get b die sticks? and would my system still run fine and my sticks at the advertised speed?

Generally most memory past 2133mhz (1066 effective) is an overclock. Nobody guarantees squat, you can view the Motherboard memory QVL list for this conformation while most QVL rated speeds do not exceed 2400mhz (1200mhz effective). 

 

System performance is heavily impacted by Memory speed. Not to mention CPU speed. 

The timing sets will vary and skew the performance depending on direct settings at X frequency.

 

Examples of "Heavily impacted performance"

 

Going from stock 2133mhz to 3200mhz is a pretty heavy performance increase.

Going from stock 2133mhz to 3600mhz is a heavier increase in performance.

 

The performance between 3200mhz and 3600mhz is less than the performance gains from 2133mhz. 

 

If you question next is: 

"What does this frequency increase really mean??""

I'll answer now just in case.

 

So when you increase memory speed, you decrease memory latency as well as increase memory Read and Write and Copy speeds.... THIS is where the performance comes from. The lower latency pretty much speaks for it'self, we don't want to wait for those reads and writes, lower latency is sought after and comes with speed and good timing sets.

thank you, couple more questions though. 1. if I do buy non Samsung B-die ram, how much would it affect my system? 2. does b-die really matter a lot for ryzen 5 3600 or would  Hynix still work fine. also I'm unable to find the qvl for the tomahawk max, any ideas where that'd be?

Yes support page here.

I cannot say that any SK Hynix Ram will post DOCP settings.

My B-Die won't even post first time DOCP settings (sig rig below)
