My 5600x wont boot with 3600Mhz DOCP profile

[OnlyAxolotl]

Just installed my new motherboard and 5600x.

 

My 6700k ran fine with 3600mhz CAS 18 ram.

 

The board goes into safe mode after multiple boot attempts if I enable DOCP.

 

I updated the BIOS to the latest.

 

What's going on? The 5600x should easily be able to handle that speed.

KLEVV BOLT 16gb CAS 18 3600mhz

try if it runs on 3200 to make sure it's just a frequency problem, then try 3600 with 1.1v on soc voltage.

When I select 3200, do I enable the DOCP profile first or not?

enable it first, then change to 3200, if it boots on 3200 but not 3600, change the soc voltage to 1.1v and it should boot.

The system booted at 3200Mhz, but why?

 

People are easily pushing 4000Mhz on the 5600x. There must be some thing wrong here.

did u up the soc voltage? needs 1.1-1.125v to boot at 3600 for some chips.

 

And i wouldn't say zen 3 boots easily at 4000, it's been confirmed not all chips boot at 4000.

I am fairly new to OC'ing CPU's. I was hoping that 3600mhz would be easy for Zen 3 just using basic DOCP settings. 

 

Have been reading about how some Bio's are bugged and not accepting more than 3200Mhz. Is increasing the SOC fully safe?

I nailed down this issue here:

You need to figure out your bootable and WHEA error free SOC/IF voltages manually by isolating the IF and leaving the memory at 2133 and bumping the IF until you run into issues, then make adjustments to the SOC voltage first, then VDDG voltages if needed.

 

The stock SOC calculations for Zen 3 seem to be out of wack. Probably will be fixed in a BIOS update, but can be corrected manually.

In my testing with Zen 3, this is unwise.  It likes a voltage range, but will straight up not boot or give WHEA errors if you give it too much for the IF frequency you're trying to get.  1.1 would result in a no boot at 1600, WHEA errors at 1800, but was needed at 1866 IFs.  See linked post above

 

"Starting high and working backwards" with voltages is a shot in the dark with this setup.  Start at 1600 IF and work up one notch at a time.

Thanks very helpful. Was worried I had a problem CPU, any way I can rule out a cpu/mobo problem?

 

 So the problem seems to be widespread? May try and tinker, have limited knowledge however.

Hmm...pretty sure if you uncoupled IF from memory inversely (manually set IF low or at 2:1) it would make SOC and IF irrelevant.  Thus proving your issue is there.
