can you open a new topic
and state the exact motherboard/cpu and ram speed and model

we can help you better with this info]]> Fri, 15 Jan 2021 21:41:13 +0000 https://forum.asrock.com/forum_posts.asp?TID=5312&PID=83114&title=ram-stuck-in-single-channel#83114 https://forum.asrock.com/forum_posts.asp?TID=5312&PID=83108&title=ram-stuck-in-single-channel#83108 Author: AINTPULNOUT

Did it run Dual Channel when doing as I suggested, using only two sticks, in slots A2 and B2?

If it did not, before you RMA to only have the same problem, pull the processor and look for bent/missing pins. This is very common with AMD when acting as you describe .

Have you tried dropping your memory speed down to 1866 and working your way up? Looking at the product webpage for your board it supports from 1866 up to 2400 if ure using all 4 slots. I know flarex is supposed to be 100% ryzen compatible but still worth a shot.]]> Wed, 14 Jun 2017 01:28:47 +0000 https://forum.asrock.com/forum_posts.asp?TID=5312&PID=31066&title=ram-stuck-in-single-channel#31066 https://forum.asrock.com/forum_posts.asp?TID=5312&PID=31065&title=ram-stuck-in-single-channel#31065 Author: TJefFreeze

The memory stick that ends in '01'(or whatever your lowest range stick is, place that in Channel A, Slot 2. The memory stick that ends in '02', place that in Channel B, Slot 2. Then the final two in Channel A/Slot 1 and in Channel B/Slot 1, perspectively('03 and 04' SN#'s). Attempt this and it may correct your situation. If you purchased 2 separate dual channel kits, find out the SN#'s and use the lowest ranged in the A2/B2 and the higher ranged in the A1/B1 channel/slots. Hope it helps, otherwise it is a separate issue that is causing your configuration dilemma.

To add to Kevins excellent post.

Note: DO NOT alter anything in the BIOS. Not setting/using XMP, no voltages, no speed,l nothing. This is for troubleshooting that I ask this.

Place two consecutively S/N'd sticks in A2 and B2, clear the CMOS(not BIOS but CMOS), reboot and do the Reset to UEFI Defaults TWICE.

It should start, don't let it enter the OS unless you know the BIOS defaults suit your need/purpose.

Power down and place the other two consecutively S/N'd sticks in A1 and B1 and hopefully power up.


Please reply back to Kevin and myself please.

Thanks. I am convinced it's a bios issue. All of my hardware is in perfect condition. I have been in contact with Asrock and they have given me a set of steps that they think will fix the issue. I am trying it today and will post the steps here if it works ]]> Tue, 06 Jun 2017 20:54:47 +0000 https://forum.asrock.com/forum_posts.asp?TID=5312&PID=30509&title=ram-stuck-in-single-channel#30509 https://forum.asrock.com/forum_posts.asp?TID=5312&PID=30503&title=ram-stuck-in-single-channel#30503 Author: pedre

Hey there, I think we are facing more or less the same problem, probably it won't help but thats the topic I opened a few weeks ago: 

http://forum.asrock.com/forum_posts.asp%3FTID=5053&KW=&title=bios-no-detecting-dualchannel-memory%20

After some testing they told me that it was caused because CPU pins are bended but i checked and they are alright so the problem its due to malfunction or a bios issue.
