Hello Guys, after few days of having a couple of 3990x here are my thoughts and doubts that I want to share with you.
First here are the most important specs of the 2 builds in order to have an idea of the experience and performance.
Build 01
3990x
4 slot- HyperX 64GB KIT DDR4 3200MHz CL16 RGB FURY series (HX432C16FB3AK4 / 64)
Zenith extreme II alpha
ADATA XPG GAMMIX S50 1TB SSD
Build 02
3990x
8 slot -x4 G.SKILL 16GB KIT DDR4 3200MHz CL16 Trident From RGB (F4-3200C16D-16GTZR)
Zenith extreme II alpha
Samsung 970 PRO 1TB
1. first of all, the performance of this processor it's just amazing, solid 18 seconds in both in the corona benchmark, slightly faster in the Build 02
/1/ in the other hands when I do the cinebench r20 I am having 24-24.5 as a score and I have seen some guys here have reported 25k, build 02 is slightly faster
2. If I speak about memory here is the tricky part , after running several tests where I tried first the stock ram speeds, 2133 for build 2 and 2400 for build 1, it seems that in certain scenarios the stock speeds are just going faster than the 3200 MHz that both of the memory kits provided (3200 MHz)
-I have seen using stock memory speeds while doing rendering around 3500-3600mhz on all cores , looks weird right?
-when I switch to the 3200 mhz speed in both setups (and making sure the timing in both kits ends in 38) I am having while rendering around 3100-3300 mhz
3.Ryzen master Wierd behavior. this is really confusing since I see in the ryzen master a peak speed without doing anything around 800-1500 mhz , while in the task manager I see around 3.9-4.2 ghz, some of you are experiencing the same'?, I don't feel the builds slow or laggy just this is confusing and want to know why the ryzen master is behaving in that way.
4. Temps are just insanely amazing, never above 70 degrees while doing heavy renderings even in a pretty low airflow spot.
Let me know if you have experienced the same issues and also if you are using the same motherboard what are your speeds/Memory kits in order to see the differences and possible issues with the ram , also looking the best ram kit for this setup, (of course, as juraj suggested there are some really good ram kits coming to the market very soon)
Best regards
