Round Trip Latency Optimization on BIOS 036 was first suggested ON then now suggested OFF what's happen??

Hi to all,

on bios 036 was suggested to leave the Round Trip Latency Optimization ON to help fix memory problems on NUC6i3SYK/H and NUC6i5SYK/H (I have in front of me the web page downloaded a week ago)...I have checked again today and now it is suggested to leave the option OFF to help fix the memory problems.

You have written on the web support page a week ago this: "There is a known issue with early versions of DDR4 memory that are used in the Intel NUC6i3SYK/H and NUC6i5SYK/H".

Now because I don't think that this "know issue" can change alone, how it is possible to suggest first to leave it on and then the opposite?

Can someone from Intel please explain in detail what this function actually does? so we can better understand apart from only try to leave it ON or OFF...

I understand that at the moment there are some problems, however, say something and then the opposite within one week (also without even specify what this function actually does) it is like saying: "to help fix the memory problems try to switch on the NUC with the NUC itself upside down..."

Hello, Topix:

Let me double check this information with the engineering department. I will be updating this thread.

Hi Amy,

cvare posted already a first reply to this question here . He did a mistake with the document.

However if the engineering department have something more to add to his reply or other useful info about this function, I think that, if you add also here they reply, it could be useful for future users that will read the thread.

Thanks

I also want to get to the bottom of this. Amy_Intel, can you please, give any reference to the doc, explaining what Round Trip Latency Optimization means?

Hello

RTL is the length of time it takes for a signal to be sent to the memory plus the length of time it takes for an acknowledgment from memory of that signal to be received. The complete round trip time taken for a signal to be transmitted from point A to point B and then back to point A.

In BIOS setup, when RTL is enable, it will minimize RT time to improve system performance.

 

I hope this helps,

Ronny G
