You can try upping the voltage to your memory .. first off, it should be at 1.35v from XMP settings.. if it's defaulting to 1.2v, then there is probably your problem .. but if it is staying at 1.35v, then up it to like 1.375 and see if that helps .. I've read in other forums about Corsair sometimes needing a little more juice to keep them stable..

something to try if you want ]]> Thu, 08 Oct 2020 09:28:18 +0000 https://forum.asrock.com/forum_posts.asp?TID=16416&PID=80422&title=x570-creator-memory-dropping-down-speed#80422 https://forum.asrock.com/forum_posts.asp?TID=16416&PID=80374&title=x570-creator-memory-dropping-down-speed#80374 Author: pr1970

Unfortunately its dropped back down the ram speed again today, so no difference in bios.
Could it be the ram being incompatible perhaps, or any settings i could tweak in the bios?
thanks]]> Wed, 07 Oct 2020 16:16:13 +0000 https://forum.asrock.com/forum_posts.asp?TID=16416&PID=80374&title=x570-creator-memory-dropping-down-speed#80374 https://forum.asrock.com/forum_posts.asp?TID=16416&PID=80039&title=x570-creator-memory-dropping-down-speed#80039 Author: pr1970

Thanks Both

I`m trying the latest bios v3.00, the cpu is AMD Ryzen 9 3950X.
Its only been a day so may take a week or so to show up if its made a difference. ]]> Thu, 01 Oct 2020 15:41:02 +0000 https://forum.asrock.com/forum_posts.asp?TID=16416&PID=80039&title=x570-creator-memory-dropping-down-speed#80039 https://forum.asrock.com/forum_posts.asp?TID=16416&PID=80025&title=x570-creator-memory-dropping-down-speed#80025 Author: datonyb

it does sound like your having an intermitant 'cold boot' fail

e.g. the system cant initilise the ram from a cold start with the lower voltages so resets bios to defaults (allthough im sure it sould reset to 2666 jedec or the older 2133 speeds depending on your ram)

whats actually happening in the background is ...........

the ram suggests its xmp profile to the bios say
3600mhz cl18/18/18 etc at 1.35 volts
the motherboard tries to 'guess' the secondary timings (there really is quite a few to set) and it all goes tits-up

the fix ?
maybe a later more polished bios
maybe manually entering the ram timings to be more suited to ryzen

or maybe both

32gb sticks are a pain in the butt to get running at 3600mhz
even more so with corsairs not so great ram sticks to be honest

you must have a third gen ryzen cpu im guessing as i highly doubt you would even get a boot on 2nd or first gen]]> Thu, 01 Oct 2020 01:57:47 +0000 https://forum.asrock.com/forum_posts.asp?TID=16416&PID=80025&title=x570-creator-memory-dropping-down-speed#80025 https://forum.asrock.com/forum_posts.asp?TID=16416&PID=79946&title=x570-creator-memory-dropping-down-speed#79946 Author: ThreeDee

what BIOS are you running .. What CPU?]]> Tue, 29 Sep 2020 10:37:02 +0000 https://forum.asrock.com/forum_posts.asp?TID=16416&PID=79946&title=x570-creator-memory-dropping-down-speed#79946 https://forum.asrock.com/forum_posts.asp?TID=16416&PID=79899&title=x570-creator-memory-dropping-down-speed#79899 Author: pr1970

Hey all


I have had this board for a few months and i notice every few weeks that it starts, the fans run high for a minute and then it drops fro 3600mhz down to 2800mhz ram.
I have Corsair Vengeance LPX CMK64GX4M2D3600C18 2x32GB

And have it set with the xmp profile in the bios to 3600mhz but occasionally its dropping its speed down.

Any ideas? I dont have any clue about memory timings, so wondering if there are any tweaks i can do.

Thanks
