X570 Crosshair Viii Hero Memory Issue

[Robbie936]

I have just installed a Ryzen 9 5900X cpu and some gskill F4 3600C16D -32 GTZNC RAM - 4 sticks to give 64GB total.

If i try to use DCOP the computer will not start, it resets after a couple of tried and then reverts back to standard setting without DOCP.

From what i have read i need to increase the DRAM voltage but being new to all of this i can't find the correct settings i need.

Is there a guide on just what settings and where they are to get me going?

Thank you

Hi @Robbie936 

Unfortunately, you will need to evaluate what frequency is possible in that configuration. I would suggest attempting 3200MT and seeing if you can obtain stability there firstly. 4-DIMM overclocking requires a more than reasonable IMC on AM4.

Thank you Silent_Scone.

From what i have read i would have been better off going for 2 x 32 GB sticks rather than 4 x 16GB sticks.

Where do i adjust the 3200MT setting?

Cheers

Extreme Tweaker > DRAM Frequency. 

Recommend using Karhu Ramtest or HCI Memtest Pro to test stability.

Cheers, I'll have a look.

The only way i can use 64Gb of ram and not get a BSOD is to leave the bios as default settings and run the ram at 1065MHz.

Not ideal but it's all a bit too difficult.

Currently trying these setting and no luck at any speed...
