Ryzen 3600x memory OC problem

[Marh]

Hi all,

 

this is my first post on forum so welcome everyone

 

i'm having problems with RAM memory speeds on my new platform.

After enabling XMP, or changing memory speeds manually mobo is trying to boot up 3 times, and then posts with resetted bios settings. No post code in those 3 attemps. ( fans/rgb are up/down 3 times )

Weird thing is, this problem occurs only on cold power up. When i change bios settings hit 'save and reset', then pc is booting up normally with desired speeds. 

Have not seen any stability issues when booted into windows - occt, games, programs ect runs without any problems. 

 

I heard ryzen is picky about the ram, but what confuses me, is why its booting up and is stable later?

 

setup:

ryzen 3600x

aorus elite b450

Gskill 2x16GB 3200MHz CL16 [F4-3200C16D-32GVK]

aorus rtx 2060

aerocool 650W psg lux rgb

bios on mobo - F40

 

I'm wondering if i shall return RAM and get another set. 

 

Thanks in advance !

I cant answer the WHY but I can tell you my 3600mhz RAM (With R7 1700) is only unstable on cold boot after a night with the PC off.  It will not post the first attempt, but will post after that and every time after that with zero stability issues (OC on CPU on or off doesn't matter)...until like 12 hours turned off then it exhibits this again.

I have the same with my 1700, X370 Carbon and memory at 3200mhz. When i set the XMP profile to 2933 i have no issues.

And also like @Tristerin If i do clock them at 3200, when they are 'warm' they will function as normal.

Hi again,

 

update : ANY alteration to memory speeds other than mobo defined itself are giving same results.

i changed memory freq 1 tier lower than 2166 and same thing happened.

 

i'm starting to suspect faulty mobo or RAM.

 

i will cannibalize other pc for RAM and check if its same behaviour.

Wait for the new Agesa update, it's very unstable right now. Zen+ did the same thing but Zen2 seems to be worst, you guys need to realise YOU are the beta testers for Zen2 and there will be a couple updates before its stable as Zen+ was before the new CPU came in. Give it a couple months and you will see a huge improvement.

@Mathieu9836 you might be right - did put different ram stick ( 8GB iridium x 3000MHz ) and worked perfectly.

Other system has ryzen 2nd gen and G.skill are working there aswell on XMP 3200. funny thing is almost same mobo gigabyte b450 ds3h

so comatibility issue 100%

 

@Mathieu9836 there is new AGESA 1.0.0.3 AB bios on gigabyte site already - you think its worth updating bios?

[Mathieu9836]

Only trying it will tell you, i know they removed 1.0.0.3ABA because it was worst then the AB version. The AB version still not stable and there is some voltage settings not working and major glitches, so yeah..... i don't know what you should do. Give it a try and if it's worst then reinstall the older BIOS update, thats what i was doing with my DS3H when i update the Bios to F30 and i was not having sound then they released F40B which was very unstable so i reverted to F4.

 

I was able to run my 3000mhz memory at 3200mhz with tighter timings on the DS3H, now it's on a Crosshair VII with the lastest BIOS with a 2nd gen Ryzen and i can't make it run at 3200mhz with very loose timings, so i will install an older BIOS update and see how it goes.

Thanks for advice.

Update:

 

BIOS F41 works perfectly - no more problems.

maybe it will come in handy for anyone.
