5600x overclock

[The Ass Man]

I was curious about the effectiveness of overclocking a 5600x. To be honest, i dont imagine the return will be worth the time spent overclocking it in the first place but i was wondering if anyone else has had good results from doing so. Currently running a rog strix b550a mobo and viper ram overclocked at 3800 cl16 and i am running games at 1440p

At most you gain 100-200MHz all core but you lose 200-300MHz single core. Depending on what you do it might be worth it, but it's usually just a waste of time. 

 

If you wanna overclock, just stick to overclocking RAM. 3800C16 is a pretty good place to end up (make sure your subtimings are tightened up well, they affect performance more than CAS latency does most of the time).

I figured as much i appreciate the feedback. Also yes i have adjusted my sub timings to 16-16-16. I tried to go for 3600 cl 14 but to no avail

It's not the time that you waste, but the additional power the CPU is going to draw. The 5600x has a max boost clock of 4.6ghz. You can most likely reach 4.6ghz with an all core overclock resulting in a slim boost to all core workloads and no benefit for gaming whatsoever (you won't lose performance though).

How much vDIMM are you giving it? Odds are you can go to at least 16-15-15 if not lower if you raise the DRAM voltage to something more along the lines of 1.5V (most you want to run without active cooling with Samsung B Die, what you likely have in your memory if you can hit flat 16s). The worst B Die kit I've owned still did 3800MHz CL16-15-13-21 on my 5900X.

It should boost to 4650 out of the box. If you use PBO and CO you could potentially see an extra 200MHz for a bump up to 4850. 5600X is rated for 65w out of the box, but I have seen 150w PPT with it and an aggressive PBO OC. With a top end air cooler it does very well.

From my understanding, the amd platform will not recognize odd numbered timings, it will just round up to the even number. But i could be wrong about that and its only for specific timings. I do currently run my sticks at 1.5v i could play around more with the timings but tbh 3800 16-16-16 is pretty fantasic

Interesting ill look into it, but would the 200 mhz bump actually make a meaningful difference? or is it basically just squeezing everything you can out of the cpu

Only certain timings have to be even, tCL, tCWL, tRTP and a couple others. tRCDs, tRAS, and everything else can run at odd timings just fine with GDM enabled. Plus if you disable GDM you can run odd timings. These are the timings I'm currently running with GDM enabled with admittedly amazing B die, though 16-15-15 should be possible to run.

To me it’s worth it..

 

Squeezing it for everything you can would be running it at 4900-5000MHz

it's worth it, going +100 or 200 is just extra performance, might not even draw extra power since out of the box stock settings are suboptimal, but zen 3 is pretty close as far as cpu goes.

I have seen 5600X do 150w PPT using PBO and ,CO.. a little more with a static clock
