AM5 Overclocking Help

[ENTERPRISE]

Hey guys, 

 

So I am now sat down with my build AM5 system, now it is time to see what extra performance I can get out of it BUT AM5 is a new beast to me and I am sure much of what applied to AM4 is applicable, but safer to just start from scratch. So I am looking for help in both CPU Optimization and RAM OC. Right now I am just running PBO for the CPO and EXPO for the RAM. My details are as follows 

 

System Specs 

 

CPU: Ryzen 9 7950X3D 

Motherboard: MSI Meg ACE X670E  (BIOS:7D69v19 / AGESA ComboPI 1.0.0.7c updated)

RAM: 64GB Corsair Vengeance  PC5-48000C30 6000MHz / CMH32GX5M2B6000Z30 (4x16GB DIMMS) 

 

According to the net, my RAM has SK-HYNIX M-Die IC's. I would confirm with Thaiphoon Burner but it will not function as the kernel mode driver is blocked or my SPD EEPROM Device is not compatible. I have disabled all Windows based security, so I will just assume its not compatible yet.

 

Just so we are all on the same page to the current BIOS setup, everything is Auto, other than EXPO for RAM and adjusted PBO. But for clarity, see below 

 

OC Main Menu 

 

OC Main Menu 2 

 

AMD PBO Settings

(No Curve Optimizer Adjustments)

 

AMD CBS 

 

Digital All Power

 

Firstly, I understand there are limits in what can be achieved on the X3D variant of the AMD CPU's so far as actual overclocking, but would love some feedback from those who have tweaked their X3D's. 

 

Secondly, I know that OC mileage will vary with my RAM config as I have a 4x DIMM config which stability wise can be more of a challenge VS a 2x DIMM config. 

 

Have at it guys. help me optimize

 

Thanks in advance,

E

Do you have any particular question about setting up your mobo settings? Or just everything from scratch? 

First of all disable all CPU things like: 

spread spectrum, global c-states, virtual machine(vt-d), core performance boost, also disable PBO completely

all the voltages, frequencies, timings: for all of them, dont use auto settings but instead dial it in. i like to use the EXPO settings at first later you can tweak. 4x16GB Hynix M you can get 6200C30 in 1:1 mode but not Much more. That will be around 1,25v soc, maybe up to 1,55v vdd/vddq but chances are you can get away with lower voltages. For 1:2 mode, what is prefered with dual ccd chips, you can use 2x16GB and Maybe get 8000 to work but i have not tried Hynix M-die at those speeds yet.

If you have any particular questions pls feel free to ask!

Hey, 

 

Well I guess I left it up to interpretation but it was more of a "Whatever recommendations" people may have.  I am happy to dial in some settings manually but I do not think I will for everything. I will disable spread spectrum, global C States. I use VM's so I will keep VT-D enabled. Actually spread spectrum I do believe MSI have hidden from the BIOS....Annoyingly. I cannot locate it and after some googling, it is a common complaint. 

 

I am currently using PBO for managing the CPU performance, might look into overlocking it, even though overclocking from what I understand is fairly limited on the X3D chips.

 

I am currently tuning my RAM, I have enabled EXPO and now tuning the timings to see what I can get. I have no particular issues leaving it at 6000Mt/s but wanted to see if I could improve on the EXPO timings and reduce the latency. Once I have that down, I may see if I can go for 6200. I tried for 6400 but the latency was poor and fiddling with the timings did not yield much improvement. I will first see what I can get on 6000 with tuned timings and then may investigate further. 

 

I will look at reducing the SOC voltage as it is in Auto and by default is running at 1.3v, I will play with that once I know I reduce that as it will just throw in another factor to consider at this point.

very nice, do you have a zentimngs sctreenshot,

@ENTERPRISE ...I am still in the process of setting up my 7950X3D (X670E Aorus Master, different bios look than the MSI). 7950X3D are actually relatively easy to oc once all the foot work has been done....

1.) Tune your RAM for all it is worth. I have a set of 2x 24 GB GSkill 7200 (SK Hynix M-die) which overclock well past 8000 w/o much trouble or extra voltage and this RAM is best served using gear2, but your kit might be different. So first thing you might want to do is to dive into the rabbit hole of RAM tuning (bandwidth and timings).  Then 2.), go for the PBO options plus Curve Optimizer (CO) either for all-core or per-core...I normally would not recommend it, but Ryzen Master is actually a decent tool to check for best cores and curve optimizations. > This link (scroll down) helps with the CO using Ryzen Master.

 

Beyond that, familiarize yourself with XBox game bar or better yet Process Lasso, given the unique asymmetric CCDs (same Zen4 core which is fantastic, but  CCD 0 has the extra cache while CCD 1 has the extra speed.
