[SOLVED] My 3600Mhz RAM runs at only 2666Mhz!?

[KurisC]

The first problem came when I noticed that my 3600Mhz RAM was actually running at 2666. I did some quick googling and found I had to enable something called XMP? I couldn't find XMP on my bios, so I checked again and enabled a pre ready DCOP profile that apparently is the AMD equivalent to XMP. This set my RAM speed to 3800.

All was good for awhile, as I did general not so demanding tasks. Eventually I played Smite, and about 10 minutes into my first match, the PC just rebooted. I thought nothing of it, but I noticed that this became a regular occurence.

At first I was told, its probably a temperature issue, so I made sure to start tracking temperatures as I was doing things, and even right up to the moment the computer crashes, temperatures are sitting pretty at around 60C.

Im not sure what else to do, I dont want my 3600 RAM to be running at 2666, and I am not experienced enough to manually set RAM speeds smartly, or to find out what is causing the issue, without any help, so I guess that is what I am here for.

Thanks in advance, and be wary, my computer knowledge is not the most advanced at all.

DOCP standard and set memory frequency to 3600. Leave the rest at auto. Did you try that? If you have a DOCP profile already at 3600 use that. Sorry I do not know your BIOS so I can't tell what your options are.

I changed memory speed to DDR4-3600Mhz and left everything else set to auto, the same thing happens. Ill grab you more BIOS information so you know what settings I have

Reviews show issues. Corsiar states Compatibility AMD X570 but review.

1.0 out of 5 stars Not DDR 43600. Likely counterfeit, look elsewhere.

I bought this for an ASUS TX570-Plus and it wouldn't clock above 2133 MHz. I tried to force 3600, and it actually refused to post requiring me to reset my bios entirely.

I figured it might be an incompatibility, so I swapped this with the RAM on another board in my studio. Sure enough, DDR 2133 it is in a DDR4 3600 package.

Could not find the RAM kit in https://dlcdnets.asus.com/pub/ASUS/...VL_3rd_Gen_AMD_Ryzen_Processors_X570_0722.pdf

If you set the RAM manually to DDR4 3600MT/s then you need to set the IF to 1800MHz and the DRAM voltage to 1.35 volts. The primary settings should be set to 18-22-22-42.

If you change the RAM to 3600MT/s then not set the voltage to 1.35 volts for the RAM, then expect a black screen and you may have to reset the CMOS.

Remember to use the correct slots. If both sticks don't work then try one at a time.

If you are lucky enough to get the RAM to work then you can test it with memtest86. Minimum 8 passes or each test done at once and 32 passes with test 7 also completed all at once https://www.memtest86.com/download.htm

If the RAM kit is faulty then just RMA it or get a refund.
