Overclocking (ryzen)

[Hamsandwich283]

so i have had this confuse me for quite some time and never could find a hard answer to the question blow, any help is appreciated.

 

i would like to try overclocking my cpu but i don't know what i should do when it comes to the clock ratio,  so the cpu is base 3.6GHz and boost is 4.2GHz, now my question is is there any-point to overclocking if i set the clock ratio below the boost? the idea i was think of was to increase the base and the boost by 0.3 for example so 3.9 base and 4.5 boost or is this just not a thing and as soon as a OC is set the boost function is switched off and it sits at 3.9 at all times?

To overclock it without setting a static multiplier you can increase the BCLK.  Does your BIOS allow for BCLK changes?

 

Keep in mind that this will increase your RAM speed also.

Ryzen has super basic down clock and voltage function when you tweak the multiplier. When it's idle (no work + no mouse movement) it sits at idle clock and idle voltage (MSI runs full voltage, which is matching AMD specified behaviour). In other words it's highly board specific

 

If you raise the BCLK instead you'll get all the auto down clocks and voltage for saving power while getting higher performance. However this is highly not recommended for those with NVMe SSDs as there are people bricking theirs as low as 101MHz BCLK (stock is 100MHz, so merely 1% overclock). Also Asus boards seem to recognize this behaviour and actively drop the multiplier... ask @nick name for that since he has the board. Even without NVMe SSDs your BCLK range is about 105MHz before something else starts to crash if the board doesn't have a clock gen chip, which should be enough to hit your target clock. Not like many 2600X can hit 4.5GHz single core stable with safe voltages anyways

As @Jurrunio said an NVMe could be problematic.  The Samsung 970 Evo handles it like a champ though.

What cooler are you using? If it is decent, you should just run it at 4.3 GHz with a slight voltage increase. Being a first-time overclocker, you should be careful raising voltage.

corsair H60 V2, idle temps is about 28-34 degrees. under load it gets to about 55 degrees

so i am running a Ryzen 5 2600x, if a set a clock to 4.2 or 4.3 for example will it sit at that or will it only go to that under load, basically i want to unlock more head room for the cpu to use but not necessarily use it 24/7 . 

[Hamsandwich283]

i remember reading about global C-states control which will lower the frequency when it is not needed, will that still work with an OC in place?

Ok, sounds like you have some headroom. try setting a all-core multiplier of 36, and see if it's stable. If it is, you should be able to get a single core of 40, with the others all above 34. Remember that if it isn't stable, you can up the voltage a little and try again. Don't go more that +0.15 volts without doing research or asking someone with experience, though. Also, what board are you using?

Somewhere in your bios, there should be some sort of "dynamic" mode (it may be called something else on your motherboard.

isn't modifying the clock ratio adjusting the base clock or am i miss understanding something?

Base clock is your motherboard chipset.

Clock ratio (or multiplier) is your processor , which just multiplies the motherboard clock.

 

For example, the standard 100 MHz base clock with a multiplier of 35 gives a processor clock of 3.5 GHz.

oh, ok, i get it, i don't know if i can adjust that value

It will sit at that 4+GHz unless you're literally not doing anything and there's no tasks for it either.

As I said, only when it has zero things to do. Even playing cat videos will pin it to max frequency

Base clock here means BCLK. No idea why they give normal operating clock the name.base clock, but whatever

Ok, you should be able to do basic overclocking with that board, but don't go "overboard" 

 

...but seriously, if you're happy with what you get, don't push it.

the clock ratio is stock at 36

Oh, sorry. I had 3.4 in my mind. Try 3.8 GHz instead.

[Tristerin]

Just set to boost on all cores and see if that makes it through benches.  If it does you are good to go higher by 100mhz, run same tests.  If it doesn't pass benches drop by 100mhz at a time till it passes benches.  Increase MHz and voltage as needed. 

 

So for you it would be a multiplier of 42 then run a Cinebench R20 pass if it holds you got a good sample.  If it doesn't downclock by 100mhz (41) and see if it will pass a Cinebench run.  Keep going up (43) until it wont hold, and increase voltage - Id start at 1.375vcore with max 1.425 with tiny bumps until stable(this is my experience with my 1700s  but at diff multipliers and have a loop on the way to tame the voltage my 240mm AIO cant handle it)

I got 2700x OC'ed to 4.2 on MSI PC Mate B350 at 1.3875v on all cores.
