Question Viper Gaming 64GB DDR4 2x32GB PC4-28800 3600MHz doesn't run on proper MHz


May 6, 2023

my ram from you just arrived today. After I build it into my PC I noticed that my PC wasn't able to boot properly after raising the MHz in the Bios. I have been testing for the last 3 hours and the current results are that if I try to use 3600Mhz my PC gets stuck in bios. If i try 3400MHz i can barely boot but the screen turns black every few seconds and then comes back for a few seconds. 3333MHz can boot the system but after opening a new Tab in my browser the PC died. It is currently running on 3266 and everything seems to work. The thing is I want to get the power I paid for so I am seeking for your help. I had 16GBRam before which supported 3000MHz but I was even able to use it on 3400MHz so I'm figuring it has something to do with the ram.

Thank you for your help and attention

from who?

if you bought the kit used or "opened package" then it's likely that the reason it was being sold was this issue you are experiencing.
no i just copy pasted the answer I sent to the amazon seller because english is not my first language

You probably blocked the memory controller and DDR4 BUS. Byebye image or processes is from powering down VDRAM or raising VDDG. Best case.

Revert Ryzen 5 to not making it worse for now. Remove XMP.

Start by finding the Uncore SoC overclock setting and set it on. Disable global C states and set something about idle activity. Put that to regular, not low activity. Make sure the IF is set to your Fclck-Mclock(1800 for 3600 MHz). Set vddg cIOD to 1.07 V, vddg CCD to 1.12 V.

Wait what. Viper 3600c20?

Is this one of these packed kits. Dual everything. Youret out of bandwidth. probably already 8 ranks there.
