XMP Profile ignored on AORUS ULTRA x570 after power cycle

[Allan B]

I am running an 3700x on Gigabyte X570 Aorus Ultra (F5 bios).   I purchased the GSKILL TridentZ Neo 16-19-19-39 2x8GB kit (F4-3600C16D-16GTZNC) for RAM and installed in A2\B2 slots as the manual recommends.  If i go into the bios and enable XMP and reboot, the system runs as expected,  Memory and Fabric clock at 1800, memory timings show as expected and the system performs well.  I have run games, benchmarks etc without issue or crashing.  Using the provided cooler the CPU temps are in the high 60's under heavy load (ex Cinebench R20).  

 

My issue is whenever I power on the computer memory defaults to running at 2133 (or 1066MHz).  If i go into the bios again it still shows XMP enabled but the Memory frequency is  2133 (see screenshot)..  All I have to do to get it to go back up to 1800 is click "save and exit" in the bios.    That seems to trigger it to go back up to the correct speed.

 

Before you say QVL, I have checked and that specific RAM is not listed on the gigabyte QVL list from their website but G Skill site claims this memory is made for the X570 and is certified for this MB here https://www.gskill.com/qvl/165/326/1562840073/F4-3600C16D-16GTZNC-Qvl.

 

I have also tested turning PBO on and found a good performance boost with it.  I am not sure if it is related but i also figured out that if turn PBO on in Ryzen Master it gets turn off after every power off as well.    Is that normal behavior?    I am not sure what settings are suppose to survive reboots, but i am fairly sure the memory should remain at 1800mhz....

 

Any suggestions or thoughts on next steps?  Should i contact G Skill support?

What does CPU-Z say? 1800mhz or 1050mhz? Might also be a BIOS issue.

What if you do it manually then what ?

Download CPU-Z, open it and go under the Memory tab, you will see your REAL timings and memory speed in there. If its a UEFI glitch it will tell you it's different then CPU-Z, if both are the same then you don't have a BIOS glitch, it's a BIOS not putting your setting down. Note that CPU-Z will tell you that your memory is going half the speed you put into the bios since it's DDR memory, so 1800mhz is 3600, 1200mhz is 2400, etc.

CPU-Z matched what my screenshot shows frequency at 1066mhz.  Also running benchmarks showed a signification reduction in performance so i assume they are both correct and it is ignoring XMP on power on.   (Bios issue)

 

Interestingly enough, the next day after this post the system would not turn on.  The power button causes CPU LED on MB to blink twice.   No fans try to spin, nothing.  I tried another PSU, removed the cmos battery (and power).  So at this point i am going to return the board and see what happens with the next one.

Same Issue here! i got a 32 gb kit https://www.newegg.com/g-skill-32gb-288-pin-ddr4-sdram/p/N82E16820232867?Description=neo%2032%20gb&cm_re=neo_32_gb-_-20-232-867-_-Product runing a ryzen 7 3700x and a 5700xt. i have sent it back and got a new set and same issue.

Manually set DRAM voltage to 1.35v, there's a known issue that sometimes XMP gets stuck at stock voltages... >.<

Yep and,

Other know issues, picky Ryzen memory controller with oddball timings, really poor performing if capable of rated speeds memory with the 32gb of memory just a tad extra strain on the IMC....

 

Really seems to be a major issue, I've seen several threads here containing it. 

A combination of all the same issue on a different PC. 

It's tough, A lot of peeps KNOW 3600mhz memory is the deal, but haven't done a great deal of research perhaps. 

 

Even at 1.35v, it's probably only going to be stable at a lower frequency. 

Giving advice is tough though. So many different motherboards, most all the same SK Hynix chiplets of poor binning.

 

Absolutely no guarantee of stable OCs at any decent frequency with 18-22-22 timing specs.  That's how bad the chips are on these sticks quiznorf has.

1.35v is the default XMP setting so it should have no problems whatsoever.

Right well, go down the thread list. You'll see what I'm talking about. Besides I had just explained what the issue is.

 

Most boards default to the XMP voltage, you mentioned an issue with early bios's which could be the case.... but I doubt it.

 

From Original Post (other has "same exact issue") and even RMAed the memory.

My issue is whenever I power on the computer memory defaults to running at 2133 (or 1066MHz).  If i go into the bios again it still shows XMP enabled but the Memory frequency is  2133 (see screenshot)..

 

It posts in safe mode, because the Ram is bottom of the Barrel.

 

Any Decent memory kit You want to get 16-16-16 timings, and Ballers get 3800mhz just in case the IF might be able to do it on their chip. 

 

18-22-22...... uhg, so much performance loss....

I have the Aorus pro and the same ram.  What you have to do is manually set the entries even if you enable XMP. 

 

So after you enable the XMP profile go to "System Memory Multiplier" and enter "36". 

 

Then go to "Advanced Memory Settings" and manually enter the timing your ram is set for so you would enter from top to bottom (5 entries) of 16, 19, 19, 19, 39). 

 

Go back to main bios "tweaker" screen and set up DRAM voltage to 1.4 (1.35 doesn't really work at times). 

 

Go to "Vcore SOC and set "1.13125v"

 

You then want to go to the "Settings" tab and go to "AMD Overclocking" (accept agreement) and select "DR Infinity Fabric Frequency/Timings" and the to "Infinity Fabric Friquency Dividers" and set it between 1700-1833 (mine is set to 1800). 

 

From there you should be set for your ram...you can go back to main menu and overclock your CPU also if you want to (if you have proper cooling) to at least 4.1 ghz by setting (CPU clock Ration to "41" and setting "CPU Vcore" to "1.4".

 

Make sure you adjust the "CPU VRM Settings" as well to...check the video ink below!

 

I got all this from Timmy Joes's YouTube site and some other sites (i'm really not that smart lol)

I hope this helps, once I made these changes on my system My 3600x was running at 4.3ghz and my Ram was reading at 3100.  Good luck!!!
