hi i recently acquired 9500x idle speed never went below 4.0 but since i flashed my motherboard to the latest firmware it now sits around 1.6 to 1.7 is this normal for 9500x
 
idling at 1.6 would be fine IMO, as long as it boosts correctly. It'll save energy and keep things cooler when not being put to use.
 
might be ECO mode or something on the board? A Bios update will reset CMOS, so if you bought the chip / board in an overclocked set, that'd be wiped.

1.6ghz at idle doesn't seem right and not heard of anyone having such low idle speed.

i know google searching most the night with no real answers or any one else having this problem could be the new bios firmware not sure if i can flash it back to the old firmware was working great till then i run cinebench multi core test scales up to 4.2 at 76oc when i try single stays at 1.7 at 38oc :confused:

You can flash any version with bios flashback i think , what motherboard do you have ?
 
I remember the days when 800mhz was normal idle speed, if CnQ was enabled.
And as long as CPU picks up frequency under load, there is no need to worry about it. CPU frequency changes on any Ryzen is instant.
Also, having latest Windows build with latest chipset drivers helps the matter ;)
 
The lowest I've seen mine drop to is 2880Mhz, and that only seems to be for a split second. It's normally at 3600MHZ when idling, and that's with every power saving feature enabled and balanced power plan.
 
The funny thing is, Ryzen Master reports some cores even going to sleep.
As I said, Ryzen came out with some extremely sophisticated power saving features and software sensors cannot read the frequencies quick enough to portray what is really going on inside the CPU :D
 
Its fine , not very often will see it go that low and stay there , will either sleep or boost higher normally , but as long as cpu performance is where it should be then its fine
 
thanks for all your suggestion but after hours of googling and going thro every bios setting under the sun i finaly found the problem was nothing to do with my bios setting i recently had a windows 10 update and not realizing it changed my power balance to power saver and drops the cpu down to 1.7 and boost's to 4.2 when in use but on the plus side got to learn a little bit more about overclocking and pbo2 :)

In advanced power options under processor power management, set minimum processor state to something lower than 100%
And with balanced power plan slider to left. That allows my CPU to idle as low as 2200MHz.
Very little difference to 3600MHz as said above, cores actually go to sleep completely, then idle frequency doesn't matter.
