Adjusting settings for the 3800x and X570-e models
Adjusting settings for the 3800x and X570-e models
You’ve gained some insight from watching Gamer Nexus and hardware unboxing videos. It looks like optimizing for Ryzen 3000 isn’t providing much extra benefit, so you might skip PBO or PBO +200. I’ll leave it off or enable it with low expectations since it doesn’t seem to cause issues. The memory tweaking appears to be the main source of improvement. I’ve started using Taiphoon Burst and Dram Calc, but Taiphoon indicates my GSKILL memory is Hynix with a D die. In Dram Calc, there’s no Hynix D die listed, so what should I choose? Also, when DOCP suggests 1:1 for infinity fabric at 1800, the auto-setting seems accurate based on RAM speed—should I just let it decide? Your motherboard is an ASUS X570-E Strix AMD R7 3800X. You spent extra for a faster timing version, which performed well but I want to ensure it stays safe without pushing it into stress limits.
Yes, there are Hynix C die (CFR or CJR) profiles available. D die is intended to outperform C die in terms of timing and voltage scaling. The timing ratio mentioned depends on UCLK, not FCLK. FCLK (infinity fabric clock) is a distinct setting you should still configure at half the memory data rate, but you can adjust it finely for higher frequencies like 1866MHz.
Hynix C might be a close match. Determining which C is closest to D depends on the specific model. The default FCLK setting is usually set to auto, but it typically reflects the slowest RAM speed for Ryzen processors. Your FCLK likely matches the timing requirements of the chip you're using. For the DOCP values you mentioned (16,19,19,39), they are indeed quite fast. Regarding voltage, Asus mentions they can use lower voltages with the same RAM speeds and better timings, especially with tools like Gskill. The Strix X570 also supports this approach. You may need to check your BIOS for detailed timing info and consider using a tuning utility if available.
honestly if you aren't running Samsung B-Die and a few select other types then DRAM Calculator is underwhelming, in which case its just manual adjustment, alot of trial and error. Also, i'd contest manual OC with CPU isn't worth it, PBO and AutoOC can be kinda crap but if 6-10% performance increase in multi-threaded applications under sustained load is appealing then its worthwhile to attempt a manual OC with static voltage at about 1.325v, its quick and easy if you start by finding stable clocks in Ryzen Master while utilizing a few stability benchmarks
I tried the official OC utility from Asus and their automatic tool gave me 1.34v and 4350mhz, which earned the best scores during testing. However, I was puzzled by the fixed voltage setting and the locked clock speed. People noted that 1.34v is probably too high for regular use, and locking both voltage and clock seemed unnecessary when the system isn’t under heavy load. Coming from an OC experience with an i7-4790k where adaptive settings worked better, I preferred leaving boost and clock flexible. Now I’m using the newer r7 3800x on auto, which handles a wider range (3900–4400) and has more stable voltage control. My main concern is the FCLK value—can you check what it’s currently set to or how it behaves in auto mode?
If temps are fine i wouldn't worry about 1.34v tbh, but if it bugs you you could downclock it slightly, say 4250-4325 or something and try 1.325. Alternatively part of the reason i like Ryzen master is i can just save the profile and only use it when gaming, leave it on auto when its just idling, or doing light stuff like surfing web. For me atleast default ends up using like 1.35-1.36v under actual load but does so at 200-300mhz lower clock speed, with newer games especially ones running DX12 ends up running hotter but also slower then manual OC, so manual OC has a time and place imo. I would only worry about manual OC at 1.325v-1.35v if a program like HWMonitor indicates the cores are for some reason spiking to more then 1.5v while turboing up, but this only happens on certain motherboards/bioses when running a OC, usually lower end ones. I had this issue with OC applied via bios but workaround is applying OC in Ryzen Master and leaving it minimized but open in backround, somehow that locks down voltages for me given i don't have best BIOS for OC on this board (b450m pro4) FLCK should be automatically set to half your rated memory speed, its probably already setup up as such, almost always is automatically. You can check it in Ryzen Master i fyou want.
I just discovered that information. It seems it will automatically adjust to half up to 3600, which matches what I have. I’ll only need to change it manually if I want to test running at 3800/1900 OC, but right now it looks fine. BF 5 and the new COD are likely the most challenging games I’ve played, and they run extremely smoothly.
