Running TridentZ RGB as per below settings, on Gigabyte Aorus x570 Xtreme

I thought 3733MHz was the best speed for memory on Zen 2 as you still run at 1:1 on the infinity fab? I was expecting latency in line with this slide:

But it looks like mine might be running at 2:1 mode? As it's nearer 80ns.

Is there any way to actually check?

The way the x570 Xtreme BIOS works is that you set memory speed such as:

36.00 = 3600Mhz
37.33 = 3733Mhz

If I try and select 37.30, it changes it to 37.33 anyway

How should I change it?
 
Hehe, I did a quick search for previous interactions and that was the only thing of note that came up.

I said certain NPC's were immortal and that you couldn't kill David Sarif.

You uploaded pictures of you doing that very thing...I didn't realise you could kill him at the end of the game :)

Tbh mate I don't know.

Is it b-die? You can find out by doing an export from thaiphoon burner.

I think your results all look good now to be honest. I doubt you can go much further.

What are your volts for vdimm?

Right I've exported both of my Thaiphoon Burner reports to Complete HTML files and imported them to DRAM Calculator.

They are both the exact same and are indeed Samsung B Die.

So should the results for DRAM Calc now be more accurate?

I've no idea where the tRFC (alt) value goes in my Gigabyte/Aorus BIOS either, I only seem to have tRFC / tRFC2 / tRFC4
