Awesome , finally you have it up and running. Keep tweaking your Ram there is performance to be found in it , keep sharing your progress and findings that might help the new comers. Thanks for the update , i do not think they have release any Bios as of yet with the new Agesa microcode. Hopefully they will announce when that happens as it will include a whole bunch of fixes and better compatibility with Ram and higher clocks for it supported too. Awesome , finally Aida64 supports correctly Ryzen 7 CPUs , nice find. Samsung B-die memory tends to be low Cas latency with even numbers ( example DDR4-3200Mhz 14-14-14-34 or 15-15-15-34. ) Cas latency on DDR4-3000Mhz ~ 3200Mhz at 16 or higher tends to be Hynix Dual Rank memory ( example: DDR4-3200Mhz 16-18-18-36 or 17-18-18-36. ) Look here: Confirmed cheap Samsung B-die Single Rank memory kit - https://www.newegg.com/Product/Product.aspx?Item=N82E16820232229 Confirmed cheap Hynix Dual Rank memory Kit - https://www.newegg.com/Product/Product.aspx?Item=N82E16820233859 I'll see if i can make a list of the kits that are confirmed using Samsung memory and post the the findings on the first page :thumbup: Looking forward to your built , post some nice pictures and share your findings and overclocks. I was told from Charles ( extremesystems.com forum owner ) that Samsung E-die to be more or less as good as B-die , it was tested by him , extreme systems owner Charles ( Fugger ). Go with the Asrock Gaming K4 , bclk not needed to reach 4.0Ghz on cpu or higher. Higher memory clocks and more memory configuration are coming with the new Bios with the new Agesa code , hopefully to be released soon. As per the Kraken NZXT X62 go for it , i have heard good things about that AIO water cooler. Great to hear you are finally sorted out your problems. We all are learning the ins and outs of this new platform , will keep learning more and more as the days go by. MSI customer support has been great to me in the past too , highly recommended.
