XMP Profile returns Overclocking Fail?

[Kheoh]

Hi all.

 

I recently got a second kit of 2x8 3600 RAM to go with my first kit, and when I went to enable XMP profile, I received a overclocking fail asking me to re-setup the settings. How do I fix this?

Thanks.

What CPU? I'd guess that your CPU can't handle dual rank at 3600

Often going quad channel can introduce issues, especially at higher mem frequency. Are the part numbers identical on both kits?

 

I recommend first running MemTest86 and verifying that there is no issues with the memory kit(s) before moving forward, if anything this is a sanity check. Otherwise you may need to manual clock your RAM and up the voltage, unfortunately it also may not be stable at 3600Mhz. This step is realiveitly easy though. 

 

What CPU and motherboard do you have?

I have a Ryzen 5 3600 and a MSI B450 Tomahawk MAX.

I just checked on CPU-Z, and the part numbers are all the same

Yea, try running them at 3200

Or its as simple as i had, ordered a 2nd set of the complete same thing just for the manufacterer to put different chips (aka non Samsung B-die) and totaly screw the OC performance...

 

You can use software like Thaiphoon Burner to determine chip manufacturer.

^{Well tbh i dont know of any other software that has this in depth info.}

How do I know if they are of different die? I used Thaiphoon and 50 and 51 are the same while 52 and 53 are different, but that means that A2 and B2 and A1 and B1 are the same kit right?

Sorry, but is there any way for me to get the full performance out of the RAM sticks?

You'll probably have to tweak voltage and such, that's beyond me

 

It's technically an overclock and not guarantee to work, by the way

Fyi the full performance is DDR4 spec wich is 2933 Mhz i believe. (edit that might be wrong i jsut read it could very well be 3200Mhz instead)
Anything above that is OC and out of spec. But yes XMP DOOCP is essentialy overclocking.

First run MemTest86, make sure there are no issues with your memory kit, if you have the all clear do so as follows. 

 

Check for a Bios update, if there is an available update that pertains to memory stability etc then I would recommend doing so, if the update is not associated with memory then I would not bother at this time. 

Go into Bios and disable XMP, (excuse the Asus terminology, it is the only bios I know well), then go to advanced settings, then AI tweaker. From there you are going to want to adjust your memory frequency, I generally recommend single incremental jumps, so beginning from 2933MHz you would go to 3000Mhz, then go down to DRAM Voltage and set it to 1.3500V, and lastly set SOC voltage to 1.100V. Save and exit Bios. If you get caught in a boot loop and the settings reset to default you know the memory OC was not stable. 

 

If stable enough to post into Windows then run a quick stress test, I recommend Cinebench R15 (runs faster than R20) and if stable restart and post boot into Bios. Also, keep in mind stable in a quick stress test is not the same as stable during a gaming session. Windows stop codes related to memory will let you know that your memory OC is not stable. 

 

If you hit instability along the way start upping the DRAM voltage by increments of 0.010V (so 1.360V, 1.370V, 1.380V... etc) until stable, I would not recommend exceeding 1.450V though. 

 

So once stable at 3000MHz you can push further, 3066MHz, 3133MHz, 3200MHz, 3266MHz, 3333MHz, and so forth, each time testing stability, possibly adjusting voltage and this is how you OC your memory, eventually you will hit a wall.

Check the motherboard QVL whether that frequency and capacity has been validated as working on that motherboard.

For voltages soc and vddp affect ram overclocking, maxes are 1.2v and 1.1v respectively, I start with 1.15v and 1v. (if you see cldo_vddp its max is 1v, so be mindful)
vddg may also help, 1.15v max, due to technical reasons doesn't respond to settings greater than soc-.05v. I would start at 1.08v (there's 2 vddg settings, I don't know enough to tell you how setting them differently turns out, I just set them to the same value)
Set vdimm to whatever the xmp profile calls for until you can confirm the dies used to avoid potential degradation.
Start by just adjusting the ram frequency and leave the timings to auto, and test. If you can't reach 3600mhz play with voltages keeping aforementioned maximums in mind, if you can do 3600, lower soc and vddp incrementally until errors in testing or go straight to trying the xmp profile with soc, vddp, and vddg set manually.
Test with prime95 large ffts, occt large data set or memory test, tm5 with the 1usmus or anta777 profile, or hcimemtest (for the free version you have to open 1 window for each cpu thread and divvy your memory between them). 1 hr should be good for confirming the frequency will run fine, when tightening timings longer stress tests are recommended.

I've heard memtest86 is unreliable nowadays.

For other people in the future, this is my current situation and how I fixed it. I am not a professional, I just want to note down how I resolved my own issues just in case someone else needs it in the future. I used to have 2x8gb 3600 ram sticks and wanted to upgrade to 4x8gb, so I got the same kit again. My computer parts are:

Ryzen 5 3600

MSI B450 Tomahawk MAX

CORSAIR CS-CMK16GX4M2D3600C18 Vengeance LPX 16GB (2 x 8GB) DDR4 DRAM 3600MHz C18 Memory Kit, Black

 

I found that I was unable to use XMP as it would be unstable. So I upped my SOC Voltage to 1.15V, VDDP to 1.1V, and both VDDG Voltages to 1.1V, while setting the timings to auto, and my ram to 3533. Although I was unable to use my ram at 3600, I was able to confirm that it was stable with those settings at 3533. I then used Thaiphoon (click read, then report, scroll all the way down and click show delays in nanoseconds then export a complete HTML file, save it and use dram calculator to import that information) and dram calculator to calculate the timings for my ram (note apparently dram calculator does NOT give information based on your ram, it gives estimates. Then, I used the information from dram calculator, took a picture with my phone and using that, I changed the tCL, tRCDWR, tRCDRD, tRP, and tRAS. I have attached an image regarding that.
