[Overclock] Ryzen 7 1700 and ram

Alvaro003 · November 13, 2019

Hi, im new to the overclock world, and im trying to overclock my cpu, but i have some questions, i heard that ryzen gets benefits from faster ram, but i made some cinebench runs with my ram at 2600 and at 3000, and the scores didnt change.. i didnt saw a performance upgrade, maybe i need to lower the timings? is that easy? i have no idea about ram overcock, im just using the overcoclk option in my bios. im using this ram: 2 x Crucial DDR4 8GB 3000MHz Ballistix Sport LT Grey @ 1496MHz (16-16-16-35) dual channel. ( i think that 1496 its 3000 just showing the 1 cicle number)

for the cpu, im with the ryzen 7 1700, using an dual 120mm AIO, currently at 3.8 ghz at 1.375v i think.. getting between 70° to 78° depending on ambient temp, i get diferent numbers on cpuid hwmonitor i get max 1.35v, on aida64 i get max 1.415 and avg, 1.37.. on cpuid goes from 1.37 to 1.4,, i dont know whats the right number..

im using an Asus TUF B450-Plus Gaming motherboard, and the bios for overclock is not easy for me, too much options i dont know...

i would need some help to try to reach 4ghz, or 3.8ghz with the lowest voltage posible, to get the best temps, and the ram to the highest speed, lower clocks posibble, to check if i get some improvement.. its that "easy" to do? or normal for a overclocker, or too hard to try with my only theorical knowledge from linus and other youtubers videos?

Cinebench isn't a ram sensitive benchmark and big changes in ram only makes a hardly detectable difference. Since you have aida64, I'd suggest the photoworxx benchmark in that as I've found it seems to scale more with ram speed, at least on Intel CPUs. I don't think I did as much testing on AMD so it might or might not be same there. Or just use the ram bandwidth benchmarks in aida64.

IMO it isn't worth aiming for 4 GHz on a 1700 for regular use, as it will require silly volts and resulting heat. For lowest voltage at 3.8, there isn't really a shortcut other than to keep changing the voltage and testing for stability. Even when you think you have found the limit, I'd recommend you give yourself some extra safety margin.
