Question Corsair vengeance lpx 3000mhz RAM overclock

[tm1996]

I have my ram at 3200mhz at 1.5v dram but whenever I go higher I crash can someone explain RAM oc ? I have a gigabyte ultra gaming mobo and ryzen 7 1700x oced to 4.0ghz

If the Ryzen builds I've worked on are any example, it would appear that the Ryzen memory controller doesn't like to run at much higher than 3000 MHz. I'm using that same RAM on the machine I'm on now (Asus TUF B350M Plus-Gaming) and it isn't stable above 3000 MHz either.

3200mhz seems rock solid, survived stress tests and 3 hours of gaming also boosted my cinebench score and FPS. Anything past 32 just crashes

Maybe the difference is you have a better board than I do.
I had mine at 3200 MHz for quite awhile, but had occasional freezeups. Went back to 3000 MHz and the freezeups went away.

Most likely due to the difference in the VRM

Make sure your SOC voltage is high enough if you are on ryzen.

Most Ryzen chips need around 1.30-1.55v on the SOC to run 3200mhz.

@ TechyInAZ
Thanks for the tip. I didn't know that. Maybe I'll put that bit of info to use and see if I can get to a stable 3200 MHz after all.
