Mine on my 3900X is set to PPT=500 and TDC=210 which is what my VRM supposedly can do safely, and no the processor will never ever draw that much and will only draw what it needs and can handle. My EDC value I set to 16 and my 3900x can hit all core 4.275Ghz, up from 4.125Ghz on standard PBO. Single core it will hit 4.65Ghz on two seperate cores and the rest in CCD1 to 4.575Ghz or higher. This is up from one core hitting 4.525Ghz without the tweak. The 3950x has a different suggested EDC value, I think it is 25 but do not recall. When I set my values to 0 they basically defaulted to the AMD defaults which is the values you started with. If I was you I would just enable PBO and that should raise your EDC, TDC and PPT settings to what the board can do. Start there and set the Power Plan in Windows to the AMD Ryzen Balanced plan that comes with the latest AMD Chipset Drivers found on AMD's site. Then if you want more tweak away. But that should get you in the 10,200 pts R20 range.
Oh and see if you can push that ram up to 3600Mhz to keep the Infinity Fabric at 1800Mhz. To keep mine at 3800, I have 3600 ram, I had to set my voltage to 1.4V for the memory. Ryzen Calculator suggested that value so I used it.
Thank you for reply
Ok, i try to use new cl16 timings to reach 3600 @1.4v / XFR 1800 but i think is hard because this modules are 3200.
i have set the PBO to advanced and set the values to "Use motherboard" because i don't knwo the exact value for this 70a vrm and 3950x. You remember a thread about it ?.
i don't want to do the best extreme overclock on the planet .. just want to use it relatively safe for life span of the hardware but with a good "optimized" OC.
Any other suggestion are greatly appreciated.
i don't have understand "what is" the Soc core to be set to 1.1.. have a lot of Vcores in AMD. i think the one on the tweaker page, right ?.
i have to set the cpu vcore to auto ?.
for VRM's what is "the high value" you suggest between auto and ultra extreme ?. you can see the bios sxreens.
Just a little bit question:
In Ryzen timings... what is (Alt) ? stands for (Alternative) ?... because in CAD_bus_Blocks i don't have any (alt) fields.
Thank you to all
Yeah... works @ 3600cl16
... thank you
. the voltage stays at 1.35 with a little oscillations but i know it's normal. i think to do some tests to verify the stability.
take a look to this bench score
... it's massive... an upgrade in BW that is the double !.
