I have this ram is doesn't say much of anything on typhoon burner other than hynix to lead me to A or M. I'm not cut in on this stuff as all of you but I can take a screenshot of something tomorrow if you need. I will say I believe it's pmic locked which sucks because I'm just shy of 6400 cl30 or 6200 cl28. It boots but fails karhu in 10-15min with 1.43vdd. I just run 6200 cl30. 30-37-37-49.

All speed ratings of Patriot Viper Venom DDR5 are unlocked PMIC and 10 layer boards.

I have owned 2 kits of them, used them on AM5, found them good.

Knock down tRFC, if it go past 160ns then is A Die.

Some motherboards have an option called High DRAM Voltage Mode which may need enabling to get greater then 1.435V VDD/VDDQ.

@scrappy_coco05 Your other thread, 6400C32 is pretty much same bin as 6000C30. One way of getting more MT/s out of RAM IC is to keep true latency same and just increase memory clock.

It's probably not pmic locked. U r not hitting those numbers could be because it's dual rank?
 
I have yes. All of them compatible including betas for 9800x3d. I should also add none of the expos worked. I think I got my first boot doing agesa and set frequency. I can't remember what was the timing it didn't like. It seems like good ram otherwise
