Rampage VI Extreme Encore XMP Ram Profiles

So i am curious, is anyone using high frequency ram like 4000 or 4266 on there Encore motherboard that is not on the QVL list? I have tried 3 different sets of DDR4 memory. 2 Sets of 4000MHz and a set of 4266MHz Corsair and Gskill TridentZ and when they are set to XMP in the bios they all show the correct timings and voltages are set but the pc just wont boot at all. These are not on the QVL list but they all worked fine on the Rampage VI Extreme Omega if i set them at 4100MHz and they were not on that QVL list either. I could get all sets to work on the Encore board but only if i set them at 3400MHz or below. I'm using a 7980XE cpu on the board. I did end up finding a set of this ram Model F4-3866C18Q-32GTZR which is on the QVL list so i'm gonna try it when it gets here and see if that works. If not it seems to me there is an issue with my board.

the entire generation its not rly been successful with setting them manually, what you can do is find the lowest initial timing that works so it sets the rtls right every boot, for me I believe it is a value of 59 in the bios

Well, maybe I kicked them in the butt about it then because I opened a support ticket for the issue describing it in very good detail and they've been banging the ticket out responding back quickly escalating the issue.. It's at their engineering level right now.. I'll report back if they give me any good news.

The lowest I could go was 68. I got a response from support and they stated the following.

Here are the rules of thumb or tips to adjust RTL - Where the RTL initial value and IO latency Offset are manually accessible, the easiest way to tighten the RTL/IO numbers is to set the RTL Initial Value to the lowest number that allows the memory to POST, then, after the system has booted successfully, to set the IO Latency Offset value higher one cycle number at a time (iteratively) until the lowest RTL/IO values are found after a reboot.


I responded that I have already done that minus the iol part, that was new but again that's not fixing the issue of the rtl jumping around sometimes. I have the system stable when the rtl's lock at 59-61-59-61 which is what it boots most of the time but sometimes it will do 59-61-59-59 and that's when it goes unstable, a tiny bit. I requested that they setup another way to set these as the omega and apex can have them set manually right? Or at least other x299 motherboards can set them manually right? Just release a BIOS with a way to set them manually.

I know that the vccio and vccsa voltages help stabilize the rtl issues most of the way but that other 10% of the time part is aggravating and it would be easier to just be able to set them manually.

In my case with 3006 bios both 59-61-59-59 and 59-61-59-61 are totally stable under GSAT.
