Question Restart loop when setting ram above 3200Mhz

[TashaD]

Hello! Likely this problem is stemming from me missing something simple in my overclocking homework but I haven't found it, so thanks in advance if you can help!

I previously had 16gb - 2666Mhz ram in my pc and just upgraded to 32gb - 3600Mhz. I checked that everything was compatible with 3600 and as far as I could tell it was. But the highest I can set the memory frequency to (Via D.O.C.P) is 3200 before it just goes on a restart loop. I had an old version of the BIOS so I thought maybe an update would help but that didn't resolve the issue either. I'm grateful for any suggestions

Cpu -> 1, 2, 3, 4 -> edge of motherboard. Numbers are ram slots.

Which ram slots are you using?

Do you have the ram in the correct slots on the mobo? A2/B2?
Also have you tried enabling XMP in the bios for the memory?

Also if you are manually setting a faster ram speed, you will most likely need to loosen the timings as well. Sometimes the gain from 3200 to 3600 is partly reduced by looser timings, so it can at times be non-productive.

CPU-world.com shows the 3700X is specified for operation up to DDR4-3200, so you may have to do a little work to get it to run at 3600MT/s.

Just because you bought fast RAM and the motherboard supports even faster XMP speeds, it doesn't mean your CPU is going to "play ball". That's the Silicon lottery.

As @KingLoki suggested, you should consider loosening the timings (after selecting an XMP speed faster than 3200MT/s).

This review implies your RAM's XMP primary timings will be 20-26-26-46 at 3600MT/s and 1.35V:

Enabling the XMP profile on the memory modules will get them to DDR4-3600 at 20-26-26-46. The DRAM voltage required for DDR4-3600 is 1.35V.

Try relaxing CL/CAS on both DIMMs from 20 (default) to 21 or 22 clock cycles. Save BIOS and reboot.

Sometimes the gain from 3200 to 3600 is partly reduced by looser timings, so it can at times be non-productive.

As @KingLoki says, configuring looser timings to obtain stability a higher speeds, may not give you any real performance gain.
