AMD Ryzen 5600x with PBO on and per core optimizer on. +100mhz on clock boost override and scaler set to x4. (holds 4725mhz all core boost for most of the run) 32gb 3600MHZ memory gigabyte X570 board BQuiet Darkrock pro 4 cpu air tower cooler CB23 score: 12122 points. stock out of the box without PBO or any settings it will score about 11000 points

Try running at 3600 and with gear down mode enabled.

Had the same issues in the past. You can enable xmp but at the same time you must manually enable gear down mode in advanced memory settings. If you leave it on auto it may not work. It should run xmp no issues

enable gear down mode in the advanced memory settings. my Vengence LPX 3600 kit would not run stable in T1 or T2 mode. been rock solid after that.

updated score. my previous best was 4032 with completely stock voltage and stock wraith prism cooler. only change i did was added a negative vcore offset voltage of -0.0850v to make the CPU run cooler and maintain higher stock boost clock longer. it's running about 7-10c cooler under full load and idle as well. running -0.1000v offset made little to no difference in temps and performance took a very slight hit? -0.1250v the system became unstable and crashed on the desktop. CB R20 score: 4196 AMD Ryzen 2700x (not overclocked) 32gb Teamgroup Dark Red pro c16 3000mhz memory MSI B450 gaming plus MAX board

might be time for a fan replacement.

cinibench r20 scored: 4032 Ryzen 7 2700x running stock clocks/voltage T-force Dark Pro 3000mhz 32gb memory

i know my original post is kinda old...but if i post this information i may help someone else's decision in the future about the Asus Prime Plus B450 so...after months of playing around with trying to correct this and many many BIOS updates which did nothing. i caved in and ended up buying a MSI Gaming Plus MAX B450 motherboard. XMP works right out of the box. was able to get 3000mhz@1.380v with no headache at all. ran 30min of prime95 blend test with no errors and been using it daily for over a week. the Asus board works perfectly fine at stock settings and is good if you have no intention of running your memory above JEDEC.

wrong edit

so after weeks of trying to figure out why idle cpu voltage is so high (and with no help from asus tech support)...i have come to the conclusion that the B450 chipset (from asus anyway not sure about others) just likes to over volt the processor by default and you have little to no control over this. i suspect because of the precision boost overdrive and xfr requires more voltage..... so rather than apply voltage as needed it just applies all the voltage as much as possible all the time (kinds ass backwards IMO) after many many hours playing with settings in BIOS i'm only allowed to apply a slight negative voltage offset and i managed to get it down to 1.35-1.4v with no load sitting in the BIOS screen. the only real world fix is to change the windows power plan from the AMD Ryzen balanced power plan to the windows balanced power plan. once i switched the power plan, windows is able to control the CPU voltage and clock speeds and this further reduces the CPU voltage to a reasonable level and temps drop instantly 10-15c at idle. under max load they are the same. precision boost/xfr still work and boost up to 4.2ghz and hold a solid 4.0ghz on all cores if temps are good. not sure why AMD or ASUS has this function cranked all the way up. i can't imagine the slight amount of performance is worth all the extra heat and CPU degradation overtime. i saw no difference in cinibench scores or any performance drop during regular use between the two power plans....it just makes no sense to me. anyway these are my findings...hope this may help someone else who cares.

I tried all different llc settings. Doesn't do anything as far as I can tell. Strange board....?

hey guys. i have a ryzen 2600x on a asus B450 prime plus board. i have zero interest in overclocking the processor(for now). i would rather have the processor and amd precision boost XFR or whatever it's called boost automatically to 4.2ghz when needed and it does reach 4.2ghz on all cores. ? i'm not sure why but the cpu voltage remains at 1.4v+ even at idle sitting inside the bios. sitting at idle it's running at 48-50c. i want to have the cpu run cooler with less voltage. asus has a option for the VDDCR CPU voltage which is around 1.18v but then i guess something is boosting the voltage to a constant 1.4v+. When i select manual voltage offset and subtract the voltage the VDDCR goes down slightly but the actual cpu voltage stays the same. if i keep subtracting the voltage even lower eventually the system wont boot. here's where it gets confusing (to me). if i select manual overclock the cpu to 3.7 or 3.8ghz THEN the CPU voltage comes down to about 1.2v and the temp drops almost 10c at idle but then the cpu is locked at that constant clock speed. is it not possible to have the processor idle at auto/stock settings with lower voltage and boost up when needed?? seems like amd wants you to overclock the cpu?

Good luck getting the memory to run at 3000+. I can't get my 3000mhz to run more than 2666 on a b450. Maybe the msi board is better than my asus but it seems to be a issue overall.

New BIOS available for the b450 prime plus. Will load and test later today.

Must be general Asus board issues. I bought a b540 prime plus and have pretty much the same observations and issues you have. Should have went with msi?
