How to get the most out of my 7950X3D combo

[P.B]

Morning all, looking for some advice on my set up so what I currently have set up is.

7950X3D
Asus x670e none wifi
64gb (4×16gb) corsair vengeance 5600mhz cl36
3× 4tb nvme + 1× 2tb p3 plus NVME
4090 Strix oc
Ax1600i

Cooling has 4x 140mm noctua 3000rpm industrial fans in the cases

Cpu is cooled by ek velocity block with mx4 paste and hooked up to a alphacool 2x5.25 bay res and d5 pump with a monsta 540x180x86mm radiator with 3x silversone 180mm air penetrator.

This is all installed in my loft eves and draws air from out side through the rad and there is a extract out the gable wall same with the pc.

So my idle temps are between 23-28 on both cpu and gpu. I was messing about with r23 last night and at 1st was only hitting about 29k but a reset bumped me up to 36k which seems like where it wants to be.

Now the issue comes with I have never overclocked or underclocked a x3d part but I feel this set up should have a lot of potential but due to having 64gb of ram everything I restart it does some memory training I assume and takes about 1 minute before it hits the bios?

So to save lots of Time and also its a right pain to go and reset the bios what sort of settings will net me both good gaming performance and all core rendering, I've enabled PBO already and downloaded ryzen master. But personally I don't like changing bios settings in Windows (just call me old skool) lol.


Anyways thank you for reading my post any help would be appreciated

Step one would be to take a monitor and keyboard up to the eaves when you’re tweaking the system so you’re not up and down the ladder

Your system shouldn’t memory train every boot. Something not quite right there. Also weird that it takes 1 minute to hit bios. Probably more like trying to figure out your hard drives.

I would watch for bios codes on startup on the mobo and see if it is stalling at a certain point and note the code so you can find out what the code relates to

ASUS boards can be a pain with multiple NVMEs if you don’t get the configuration spot on in BIOS

Another double post…. Not sure what’s going on when replying from my iPad

I shared some advice on the basic setup required for dual CCD X3D here, might be worth a quick read.

In terms of tuning hardware, first thing to do is make sure you are on the latest BIOS for your board. Next use the latest Chipset driver from the AMD website. Third read my linked post above.

Start by tuning memory with either TM5 (25 runs 1usmusv4) or Karhu RAM test (with CPU Cache enabled minimum 8 hours run time overnight). During testing you should have a fan pointed at the DIMMS as a temporary measure while testing.

First find out if your memory is Hynix or Samsung, as that'll affect the timings you can use. Pray for Hynix. With 64GB, aim for 6000C30 timings as a starting point.

Once memory timings have been dialled in and confirmed stable using tools above, (happy to provide some suggested timings if you share a zen screenshot), you want to set FCLK as high as it'll go without causing instability or performance drop offs. Karhu is good for checking FCLK stability. When the test is running, if you hover the mouse over the % sign on the Karhu window, it'll show you the speed its running at. This can be used to verify that performance is where it should be. You'll need to wait till about 500% before the numbers become accurate and start to level out. Prior to that they can peak higher and lower a bit. Share a screenshot with me near the time and if you see the MB value dropping lower, you know it's performance throttling. You can check as you increase FCLK clock that it is scaling properly from 2067Mhz - 2100Mhz, etc.

See my post here for suggestions on how to tune curve optimiser. This helps increase CPU clock frequency by reducing the voltage applied to cores. It's time consuming but worth doing over time.
