Too many Ryzen MBs don't have BCLK adjustable. I had to trick mine just to stay at 100 otherwise it was fluctuating between 99.6 and 99.9.

 

Failing to understand what this has to do with me asking peeps who use BCLK to post their results ....

Of course some motherboards dont have such adjustments.

Dont know how you "trick it" usually you just disable "spread spectrum" if that option is available to you and BCLK will be at 100 mhz.

I don't have scores to post, but just wanted to say that with the system in my sig I can only get it to 101.2, maybe 101.4, but just leave it at 100. When I had a 1700x cpu, everything else the same, I had it up to 106.something. And it actually made my 970 m.2 scores improve as well. Not by much, but you could definitely see it, beyond normal deviation.

I had to limit PCIe to Gen2 and after that I could push BCLK upwards and onwards.

As I am using a 3600 its essentially super charged my CPU, get the best of both Worlds when combined with the EDC bug

does limiting the pcie to gen2 affect your m.2 scores?

 

Nope, performance increased due to the BCLK

 

I can get 108 BCLK on my board. I have to go to PCIE2 over 105 on the BLCK. Don't make fun of my A320 motherboard! LOL

 

Excellent!

Thanks for posting

 

Which Mobo is this and what ssd/m2 do u have active while using this BCLK?

BTW your CB15 is low if you run all cores at 4.500.
Mine is 1806 at 4.441mhz.

 

everything is in my sig

But I am not running all core at 4.5 Ghz, I am using BCLK with EDC bug and the score is fantastic for an everyday workstation rig, this is not a benching rig....

So my clocks auto adjust according to what is being demanded of it.

So if a "light" application needs to pull + 4.6 Ghz from a core it can do

 

I would like to increase the BCLK, but if i set it to, lets say, 101 than de cpu wont boost anymore. It just stay on 3600 MHz. I have an Asus PRIME X570-PRO with the latest bios and a Ryzen 5 3600.
I can't understand why he do that

 

Did you try disable/enable "C-States" & "Core Performance Boost"? Don't leave it on auto! I had to disable those setting for it to work or I get the same bug as you.

 

Here is my bclk overclock with Ryzen 3300X at 103.5 FSB. I use every day with these settings, have found it rock stable. SSD also performs awesome, seems bclk has some good effect for everything.

 

Very nice results.

PCIe is set at Gen3/4 ?

 

I loved BCLK overclocking with my 3900X, gave great multi and single scores. I remember getting 218 (219) on CB15 single score. Loved undervolting, PBO, and bclk combo with that chip. However my 3950X hates it, it had different boosting behavior. Once I enable PBO it would try to hit an all core of 4.2 with only 1.1 volts causing weird instabilities. I would raise vcore to fix the issue but then single core would boost to 4.7 to 4.75 at the expense of 1.5volts. Add bclk to the mix and a whole crap bag of issues.

However the 3950x is great for all core/per ccx overclock and settled for a 4.40/4.45/4.3/4.25 with only 1.25vcore (1.19 under load) and with the ryzen balanced plan the cores and voltage still downclock.

 

So with a higher BCLK you need to change PCIE to gen3 from 4 to get it to post? Gonna try that

 

Or Gen 3 to 2

It depends on your hardware, I think mainly the VGA ..

 

Nothing to show, but this 1700 has been running at 3.925 ghz with 103.3 bclk for three years now. Never bothered to push it farther.


In win10 I set the power plan to "performance" and then in advanced settings I think it is, there is the option to set the power states. 100% is standard but if the minimum is set to 40% or so the cpu downclocks just fine.


This is a pic I took after a gaming session on a hot day 6 days ago.

 

Dont know how much more headroom you have left on your 1700.

The great thing about BCLK on the newer batches of 3600 is that these CPUs can handle the higher clocks, its just that they have been limited to their current frequencies due to product segmentation.

Using BCLK is allowing these CPUs to stretch their cramped legs

 

Not much of a BCLK OC but not sure where I should post my max frequency validation.

Does playing with the BCLK effect M.2 drives?

 

It makes them faster

 

I no longer have the hardware but I did 131.0 BCLK on Ryzen 1700 + X470 motherboard when I was testing it out.
I have to say gen 1 Ryzen had no benefit from it, they just run hotter for no increase in performance, just do a regular OC instead.

X570 just doesn't allow it due to SATA issues. (you need to stay on only m.2 there)
I hear B550 does allow for SATA to be used even with BCLK.

X470 was limited to ports 4-5 SATA to be used, you could not use 1-4 as far as I knew. (you would be severely limited otherwise)
Your VGA will have limits on what they accept. My RX 480 just would not give a display above 131.0BCLK and that was my limit.

What motherboard was that for the 131 BCLK, that is a stupendous frequency, for sure the motherboard must have had dedicated clock generator for PCIe

 

Just a heads up with my experiments on the MSI X570 Unify.

The PCIe SATA card I purchased is running all my SATA devices with no issue with BCLK @ 107.60 mhz.

Only issue I had was that the PCIe device I bought is not compatible with UEFI so I am having to change the location of my OS as I cannot boot from any of the PCIe SATA device in UEFI mode.

Switching to CSM makes booting possible and this is what I will have to do if I ever need to boot from a DVD/CD which is very very rare.

So by using a PCIe SATA card I can use my 3600 in "steroid" mode

 

Sorry for the thread revive. But I would like to know which motherboards are good options for BCLK overclocking. Because I want to push my 5800X3D a little harder and the only way I can do that is with a BCLK OC.

 

Go to AMD Motherboard forum...might have more luck than Malema.
