Thank you for your reply!
1) I live in Estonia (in EU) and I hope my English is good enough for most people to understand ;-)
2) I might put in Ryzen 5600X or even Ryzen 5600 if it will be available early Q1 2021. I also have another PC with ryzen 3600 which might go into this build to save costs. Ryzen 5600 is rumored to be costing around 220$. I also chose B550 for WiFi6 + Cooler VRM + Bios support for Ryzen 5000.
3) 32GB RAM in not really an absolute must but I was thinking it might give me some kind of future proofing. I also play some games using multiple account + windows open at the same time along with dozens of browser tabs. So 16GB might not be enough for me. It is also bit harder to OC higher RAM densities as far as I know.
I'm also waiting for some RTX 3060 TI itx or most likely RTX 3060 itx GPUs to come out because RTX 2070 itx cards are way too expensive if bought new and rtx 2060 with it's 6gb Vram looks lame to me.
I'm a bit sad to hear that you gave up on buying this ultra-rare RAM with mythical D9WFL chips but I can understand why. Also thank you for an advice about Toabao sellers. Could you please recommend some cheap and reliable agent for EU deliveries? So far I found TaoPal.
Another thing about the Chip Dies. I've searched some other forums a bit and some guy was saying :" B-die does timings better, while Rev E does frequency well." But when I go to Ryzen Dram Calculator it and click "calculate safe" it sets timing lower for E-die than this B-die.
Then I looked some things up in the Dram calculator and it also showed that there are Micron E/H die, Micron A die, Micron B die, Micron D die. I even wonder if server memory is even available with those. There are also Hynix and Samsung four types of Dies each ;-X I'll do some more research on what's available for VLP RAM and which Dies are the best for ryzen CPUs in terms of OC. But what I have understood so far is that Micron dies are best for Ryzen. Correct me if I'm wrong please!
