Hi folks! XMG Apex 15 - Shop Website: https://bit.ly/2EkRJ85 I already uploaded an early review about my Schenker XMG Apex 15 after just one week. Because I couldn't stop I made this followup tuning guides and investigation videos after another 8+ weeks of use, divided into multiple parts. This is part 2. Early Review 1: https://www.youtube.com/watch?v=Sb_8zXRDqRg Tuning Part 1 - new BIOS & CPU OC/UV: https://www.youtube.com/watch?v=FtLzR-i8XmA Tuning Part 2 - memory tuning #1: https://www.youtube.com/watch?v=qCkNcZ6WEQQ Tuning Part 2 - memory tuning #2: you are here Tuning Part 2 - memory tuning #3: upcoming Tuning Part 3 - ??? Hope the video can help all Clevo NH57AF / NH55AF / XMG Apex 15 / ... and all the rebrand owners out there.

Road to reach 3600MHz: Translate your 3200MHz timings to 3600MHz after you found tight ones. BUT also add +1 to tCL and adjust the other timings correspondingly for a safety margin. Use CAD drive strength 40-24-24-24 Worked for Samsung B-die and Hynix CJR. Don't forget to test all settings afterwards! Here are some settings for the tested modules (Corsair Vengeance 2666 18-19-19, G.Skill Ripjaws 3200 18-18-18) Disclaimer: Your mileage may vary. Each memory stick is different. If they do not work Reset BIOS and try with tCl+1 and adjusted timings as explained in the video. It's well possible that you can reach even tighter values. Memory overclocking is no exact science and there will always be differences in each memory stick, motherboard, cpu memory controller and thermals. The following settings are not fine-tuned. .
