Hi guys, So I'm trying to get my new Ryzen build stable at anything over 3.8ghz and realized i cant do it due to my ram timings and speed changes never sticking after i change them.

I can stress the CPU no problem but will crash as soon a i do anything ram intensive.
By default my motherboard (gigabyte x370 gaming 5) set my ram to 2133mhz with 15,15,15,36 timings which is below my ram's rated 16,18,18,36 which i believe is causing my ram to be unstable.
The main issue is that i cant change them, Ill change the timings and speed in the bios and it'll boot but the changes don't stick, all programs including Ryzen master report them running at default 15,15,15,36.

any ideas ?

LOL I don't know how gigabyte can classify that bios as stable, even SIV shows you as being on Bios F3, something very strange is going on, not sure which software to believe, I would expect the bios to at least get it right, but you've just broken all world records if your CPU is really doing 6.7ghz lol.

2133mhz CL15 is spd of your ram, with the other timings you have listed I would say XMP of your ram is 3000mhz, exactly which ram do you have ?

when you manually set speed and timings, does the board power off and back on again multiple times before actually starting up ?

instead of doing that, load xmp profile, and dial down the speed to 2933mhz, leave timings and voltage alone, XMP profile will sort that, also add a tiny bit more voltage to the Dynamic SoC voltage, if it works like mine then +0.090v on top of stock voltage should be enough, never allow that voltage to go higher than 1.2v in total, this is north bridge voltage which includes the IMC, all built into the CPU.

also ive just noticed you are running 4 sticks, that puts a tonne more strain on the CPU, you may have to dial down to 2666mhz and if possible, just change command rate to 2T, AMD boards default to command rate 1T.

memory timing mode to auto
memory voltage mode to auto
as you've already set you CPU core voltage, set your Dynamic Vcore (DVID) to normal not auto.
did you set Vcore SoC to 1.2500 yourself ? says your stock voltage for this is 1.1v ? nothing higher than 1.2v for this max,I would bring this down to 1.15v myself, you don't need a lot more.
set Dynamic Vcore SoC (DVID) to normal not auto.

Auto voltages are bad for things, you never really know what the bios is throwing through things extra.

SoC voltage is a strange one, too much is just as bad as not enough.

once you save and exit, go back into the bios and post another pict of what your voltages now say please.

could you post a picture of CPU-z please, the memory section, I would say CPU-z is reporting it wrong, CPU-z wont even open on my Ryzen system as I'm using AM4 RAID, so its still very buggy, try AIDA64 extreme version https://www.aida64.com/downloads/ODlhYmU3NWE= see what that says for timings etc.

this may help a little, fast forward to 1min.30secs https://www.youtube.com/watch?v=bf3nsels8B0

It is very strange, does the bios show you if the ram is running at the speeds you've set, theres like a little flyout menu on the right of the screen, if you hover over it, it will show you cpu speed and ram speed etc.

The guy in the video just hard entered all of those sub voltages to normal, all your sub voltages are already running at those voltages, not quite sure why he's pushing 1.4v through his ram, you could give it a try, but I think its the software playing up, check first and see if the bios is reporting your memory speeds correctly in that fly out.

is your bios upto date ? also, what does the Gigabyte software say your ram speed is at, SIV, (system information viewer)

Here's the bio's and siv info.
Also the fly out menu is going nuts haha (second image) the bclk speed jumps all over the place. its only doing that in the bios and it dosnt happen after boot.

Yeah I've got f4 (newest stable bios) running. But I'm flashing the 2nd bios to f5g (beta bios) to see how it goes

Yeah i should submit it to overclockers haha.
I finally got a ram setting to stick with this new bios. looks like max is 2666mhz with 4 dimm's atm.
