I have a gigabyte b450 and got ripjaws 2x8 ram at 3600 with a ryzen 3400g would I be able to overclock the ram and if so how
 
Solution
Not only is overclocking the RAM a bad idea, because it is already very fast and there is an EXTREMELY involved process for verifying stability after overclocking or changing memory timings, but even more than that is the fact that you can't go past 3600mhz on the Ryzen 3000 series platform anyhow without paying a penalty, as explained here:


Conclusion: Common RAM Mistakes with Ryzen

For anyone who isn’t interested in manually tightening timings and adjusting voltages, a 3600MHz XMP kit like this one or a high-quality 3200MHz kit is the obvious choice. 3600MHz is the clearly defined limit of easy performance gains from memory frequency on Ryzen, and we saw our 3200MHz CL14 TridentZ RGB kit perform at...

For anyone who isn’t interested in manually tightening timings and adjusting voltages, a 3600MHz XMP kit like this one or a high-quality 3200MHz kit is the obvious choice. 3600MHz is the clearly defined limit of easy performance gains from memory frequency on Ryzen, and we saw our 3200MHz CL14 TridentZ RGB kit perform at nearly the same level as G.Skill’s 3600MHz CL16 kits in most tests when using XMP--timings are important. For what it’s worth, we didn’t see glitches or huge performance losses past 3600MHz in any of the tests--performance just stops scaling or takes a minor hit.


On platforms where fclock can be pushed a little higher than 1800MHz, it may be worth considering a 3866MHz kit, although we gather that achieving 1900MHz fclock is relatively uncommon and pushing mclock isn’t really worth it if it means giving up the 1:1:1 ratio. AMD does indeed have decent plug n’ play support for kits >3600MHz, but making these kits actually perform better than their lower-frequency counterparts takes some manual tuning of timings and luck with components. Users will likely see far greater performance gains from buying a trusted 3600MHz CL16 kit and following the Ryzen DRAM Calculator’s recommendations than they would from trying to run a higher-frequency kit.

Besides which, your 3400G is not a Zen2 processor. It is a Zen+ model and as such, plus the limitations on B450 chipset motherboards except for the MSI Max models, you are probably going to be limited to 3200mhz maximum anyhow. IF, IF you can run them at their 3600mhz speed and not have to drop them to a lower speed, you will be very fortunate and should be happy with that and not try to take things any further. I'm not aware of any current Gigabyte B450 boards that support faster than 3200mhz in reality, regardless of what the product page might say.

After 3200mhz theres really not a point hes right. With ddr3 you can get nice gains with better timings and faster speed from 1333 to 1866 or from 1600 to 2133 mhz example. But after 3000mhz+ ddr4 gains are minimal.

EDIT: this is for gaming only

No, there are gains to be had all the way up to 3600mhz on Ryzen. However, it is simple math that tells us that those gains are outmatched by a slower 3200mhz kit that has a CAS 14 latency. If you get a 3600mhz kit with a CAS 14 latency, which is expensive, then you will remove any advantage the slower memory might have had.

3200mhz CL14 is just slightly faster than 3600mhz CL16. 3600mhz CL14 is moderately faster than 3200mhz CL14, but even so, the difference is probably NOT enough for the average person to even identify, except by way of synthetic benchmarks other than a slightly "feeling" of the system being a little bit "snappier".

For gaming, that probably doesn't translate to anything substantial.
