FYI - The 7950X can pull this off but the 7950X3D seems to only be stable at 5600Mhz. Can only find 7950X users with the ability to run over 5600 without issues.
You had me lolling when you said overclock forums don't talk about resistance or ohms. Hope you start making video's showing how to properly overclock & tighten DDR5. tRFC & tREFI can be much lower than you have it now.
I’m trying to get my system stable but it’s driving me insane I have a 14900KS and 4 sticks of ddr5 ram @6400 and it won’t be stable with xmp on. It will BSOF whenever I launch a game. I also cannot find where I adjust the ohms or impedance with my asus z790 hero board in the bios
Forgive me for asking, I have never overclocked anything in my life. I have bought new system 7950x3D with 2x (2x 16GB) DDR5 6000MHz memory (4 sticks), believing that it means it will run at 6000 by default. Turns out I need to run some EXPO profile, but that profile does not work with 4 sticks in. The system simply does not POST, and I need to clear CMOS in order to get to BIOS again. If I understand correctly you are suggesting I should change ProcODT. What are recommended options? DOes this value regulate the impedance of the circuitry like adjustable resistor? MY system behaves as High Impedence from your video, should I go lower values? Is there are risk of breaking anything by using this setting alone?
4x 16gb should work without needing to change ProcODT. You need to be on the latest bios because the older bios may not know to change the voltages to match the memory profile. That being said, 4x 16 at 6000 is considered an overclock as isn't guaranteed. What does the memory currently post at? Is it 3600MT/s?
@@GameTechReviews Yeah, 3600MHz. And update of the BIOS was the firs thing I did. I have since lowered my expectations. I am currently trying 5000MHz at 30-36-36-76 @1.4V. It posts, but memtest86 shows errors and crashes...
@@jamerduroligelle91 Sorry mate, I have only partially managed to fix the issue. I have since discovered that I have other problems (BSODs) with my build and I don't think those are memory related. But if memtest is to believed I have managed to get to 5800MT's fairly easily by just loosening the timings to 44-44-44-90 and surprisingly lowering the voltage from EXPO 1.4V to 1.2V
This is really good information. Someone who seems to know the why to what he is doing.
This is the video making me subscribe to your channel. Keep this content up and have fun :)

Just rewatched your initial, hands on video and this one is a great follow up.l 👌
