OC & Modding Post your overclocks !
- Thread starter bottle
- Start date
More of an optimisation rather than an overclock considering I am on a laptop with Ryzen 4800H and RTX2060. I have reduced the CPU TDP to get more out of the GPU and quite content with the gains. Screenshots below are from TimeSpy and FireStrike at 1080p with my settings on the left and stock on the right.

If you are running it at 1.4v don't!!! it will reduce your cpu life severely. I have mine 4.6 at 1.3v with llc 3 and anything above requires way more voltage.CPU : AMD Ryzen 5900X @ 4.7Ghz OC
Ram: Crucial Ballistix sports 3200mhz @ 3733mhz cl16 OC
AIO: Lian Li Galahad 360mm
Use the curve mode in bios with PBO+ instead of a hard oc like this.

Nah i tried curve oc but much happier with a fixed oc instead.
AMD processors are good with 1.4v as much I know. my phenom x II 1055t is still live and heathy. plus I think its totally depends on the temperature. right now they are fine and so no issue i suppose
correct me if I am wrong

No brother. Can't compare different generations and voltages matter as a lot with these newer cpus. Just Google ryzen 2nd/3rd gen safe voltage. If you are pumping 1.4v at 100% load believe me your cpu life will degrade very fast. Have read a lot about this as have had 3900x and now 5900x. Trust me those 100mhz are not worth the 1.4v

it depends on process node, phenom 2 were 45nm and many had 1.4v as stock voltage.AMD processors are good with 1.4v as much I know. my phenom x II 1055t is still live and heathy. plus I think its totally depends on the temperature. right now they are fine and so no issue i suppose
For smaller node the voltage have to be lower for longevity.
Some more tips
More important than the average core voltage is peak core voltage, if your cpu is idle ( running at lower clock and voltage to save power) and then you apply some load then the transient response will be worse and cause voltage to over shoot ( it can go 1.7v+ if you set 1.4v load voltage and if it idles down to say 1v ) for micro second which cause silent degrade or even dead cpu or board if vrm is bad. So i will recommend to turn off dynamic voltage ( that is voltage never idles down ) so that vrm doesn't need to overcompensate for the sudden load.
Also always use LLC to introduce intentional voltage droop, that is your max load voltage should always be lower than your idle voltage. ( eg 1.35v at idle, and 1.25v at 100% load ) this is to avoid spikes during transient, as those spikes will go much above your desired load voltage. These can only be seen via oscilloscope, AHOC ( buildzoid ) have several videos regarding these.
1.3v for 4600mhz recenty crashed my system
is this regardless of low temp ?
1.4v long term will fry your cpu irrespective of temperatures.1.3v for 4600mhz recenty crashed my system
is this regardless of low temp ?

yes, specially voltage spikes as temp won't increase due to those mili/microsecond spikes1.3v for 4600mhz recenty crashed my system
is this regardless of low temp ?

so did any one try newer version of clocktuner 2.1 , takes 4 to 6 cores of zen 3 slightly beyond 5ghz

Those clocks are meaningless tbh. Not one task will actually happen at that ghz. That is just idle boost.

At what voltage?
