Unstable Memory Speed

[Cjz]

Hello everyone recently i bought 2 more stick of ram and install my motherboard all 4 of my rams are the same but i cant run all 4 of them at 3200mhz stable pc keep turning off and turning on until hit the bios with default 2400mhz speed but its stable at 3000mhz is it worth up the voltage to 1.35 from 1.4 if its gonna make the ram stable or should i leave it on 3000mhz i dont think 200mhz gonna make huge difference but im open on any information.I also try separately in case one of them was the problem its not even with 3 sticks cant run 3200mhz (Btw before i try new 2 stick pc was running 3200mhz fine with 2 sticks. btw all of my rams are the same and same latency down below i show you the ram) my cpu is ryzen 5 5600 and my motherboard is asus prime b450m-a II

This is likely the reason:  asus prime b450m-a II

 

Ill pull up the owners manual shortly here

The board doesnt state in the manual that i could find that using both channels can have a reduced frequency (example, my ASRock B450 with 4 sticks runs at a lower speed than in the A1/B1 config per the manual).  

 

Are you on the latest BIOS revision?  Each update adds more compatibility across brands etc (especially if you are mixing RAM modules of different bins etc)

it would be great its says it can support up to 4400 mhz but doesnt actually say how many ram can use that speed.

tbh i dont really know how i can check my mobos bios but i can say i didnt do any bios update for 5600 its came like that in factory i use the 4 same brand and model but i didnt buy them all in one i bought it separately but i make sure that all of them are the same model and same speed and latency.

Are you using the DOCP/XMP profile or are you setting timings manually? The profile is only optimized for running a single stick at 3200mhz. Normally you would buy a kit with 2 or 4 sticks. Try settings frequency manually to 3200mhz and setting primary timings to 16-18-18-36 like so, in BIOS:

If it doesn't work, try increasing voltage to the memory controller a little bit. (if you set to auto, it should up itself a bit, so I would try that first).

tbh when i try to select docp even doe its says 3200mhz doesnt set my ram to 3200mhz even before i run 4sticks. it was always sets 2400mhz i dont why but also i have 2 docp profiles one is 3200 one 3000mhz i usually choose 3200mhz docp and also manual set to 3200mhz

Turn off PC, press and hold F2, turn on PC, will go into ASUS bios.

 

But Im an idiot, that CPU is not gauranteed to run at 4400mhz.  3200mhz only

I dont if this help but on CPU-Z its like this

Alright, try setting this manually instead. Yes the kit comes with two profiles, and the profile will set sub timings aswell. Apart from being optimized for intel and not amd, it should work, but only guaranteed to work with one stick. Does it make sense? If you set the primary timings to 16-18-18-36 as well as manually setting voltage to 1.35v and 3200mhz, all other timings will be set by the motherboard.

i didnt touch any of the timing because i dont know anything about them but will give to try if i have to do it manually.

Yes set it manually and it might just work without you doing anything else.

primary timings to 16-18-18-36 as well as manually setting dram voltage to 1.35v and 3200mhz

just try it when switch to profile 3200mhz docp its automatically sets all of them 16-18-18-36 also voltage sets 1.35 automatically too

[Cjz]

My Bios version and also the ram settings in bios @DoctorNick @Tristerin

Yes, thats the point. But it doesn't work right? Thats why you'll have to do it manually.......

Put it were you had it, then highlight Dram voltage push the + once or twice

What I was getting at, and had forgotten, is that the CPU itself, has its own memory controller.

 

So does the motherboard

 

Motherboard can go up to 4400mhz per the manual

 

CPU can go up to 3200mhz per the manual

 

Lowest common denominator is spec, anything else is overclocking.  Id manually set it to 3200mhz if DOCP is having an issue (and make sure BIOS is up to date)

well i did disable doc and set everything myself manually and didnt work i guess cpu can run 3200mhz with only 2 sticks and not 4sticks. im fine with 3000mhz tbh i just wanted to know if i was doing something wrong. also my bios up to date

Swap the kits around to and try agian, should support 3200mhz, but could be the board as a B450 and they just dont have that listed in the specs (as well)

will give it to try in the future thank you all for inputs and suggestions
