I wonder how your performance is.

Because it seems that in my case it's not so much about the clocks, but that this method is really slower then the manual oc of all cores.

I do in my Wife's PC. She has my old B350-F Strix with a 3600x in it. I used the exact settings I posted the first time and it gets 4.35ghz all core and 4.45 single threaded. Eventually I want to work on the ram OC but she uses it everyday haha. Maybe I will tell her to go on shopping trip one of these weekends

When you get the time, can you run a CB20 and geekbench 3?

could you share the link where you mentioned the settings you used?

So this is I believe the difference with the manual OC.
All core OCing at 4.4Ghz with your Ram timings should bring u a score around 4000.

Hi!

Im pretty sure that 4.4Ghz fixed CPU core frequencies are not going to equal '4.4Ghz' CB20 score achieved through PBO, even with the use of the EDC bug.

The EDC bug will raise the 'auto' all core frequency of the CPU, while at the same time providing higher single core boost speeds.

If you have work loads that use all you cores and are not bothered about the lower single core boost clocks then there is really no reason to be using the EDC PBO bug.

Now for those who dont mind slightly lower all core boost frequencies compared to static frequency overclock (EDC bug is definitely better compared to 'regular' PBO) but would like nice single core boost speeds this bug is great.

Though alot of work is needed to find a balance on achievable boost speeds as the cores all differ with regards to max frequencies .....

Myself personally, the highest ive hit in CB20 (using EDC bug) is 3927 and the all core frequency according to HWinfo64 was alternating between 4280-4300 mhz.

To confirm my theory, can you run a 4.3Ghz CB20 and post back you score.

Im guessing it will be more than the 3927 I achieved....

What settings do you use on your 3600x?

Exact setting in my sig, which does NOT use EDC bug.

For EDC bug testing, I used.

EDC: 3 or 4
TDC: Auto
PPT: Auto
C-States: Disabled
CnQ: Disabled
Spread Spectrum: Disabled
CPU Scaler: 4x
CPU max frequency boost: 75 mhz (edit, had a missing 7, not 5 mhz)
CPU Offset: +0.0250
CPU LLC: 5
BCLK: 100 mhz

But I could not get this stable under intense and long duration stress tests !

Also I run all test by changing CPU affinity for CB20 to realtime.

This make sure you get consistent scores without being effected by other processes.

It will look like it has frozen, but it has not
