  1. very nice! With the 1,5 and 1,55v ram voltage you can set C30 or C28 pretty easy too, and you can tweak SCL's down to like 8 8 , then 5 5 then 4 4 then 2 2 if that works ! Also RRDS / RRDL tFAW you can try 4 8 16 and WTRL 16 or 14, Also VDDP voltage can go lower but not neccesary. I set it at 1 or 1,05v and it works with everything. Lower is better! Also MISC, really to 1,1v. mem VPP 1,8. 

    If you can find GDM set it to disabled for better latency, and somewhere in Training option you can find round trip latency , set that to enabled. If GDM doesnt work anymore leave RTL auto.

     

    Where do you tweak your RAM timings? tRFC has to be in the menu just below tWR and tPAGE

     

    oh and set MCLK:FCLK 1:1 mode

  2.  just installed a 7500F and loaded up a profile image.png.76beedf08d2ee532ad828e321aa8dc42.png  dont need those high voltages. can set 2200 fclk as well and go tighter with RCD etc. with same voltages. Also try to manually tune down drivestrenghts and procODT. Also set tRFC 165ns just to try out, because 120ns is very tighht

    1.35v Misc voltag

    no thats way too high? 1,1v Vmisc is always good. You need to give the VDDG's more voltage to get higher FCLK stable, ive set mine 1,050v and 0,950v (stock is 0,850v, you can set it up to 1,2v both)

  4. maybe you can scave off latecy by settings things like TSME diabled, GDM disabled, and Nitro training settings not on auto values, finetuning voltages and higher/lower fclk can help getting a few miliseconds of. tRFC to around 125ns i think with the M-dies?

  5. v misc at 1,35v?

    So much great info here and thanks so much for including ZenTimings in your screenshots.

     

    I have G.skill Flare X B-Die DDR5 and run it super stable at 6200MHz cas 30 1.435v, with the IFclk at 2100MHz. VDD_SOC is 1.25v and VDD_MISC is 1.35v. Mem controller voltage is on Auto but giving it 1.465v or something like that.

     

    It's passed 2 hours of Memtest86 and 4 hours of GSAT in a terminal in Linux Mint.

     

    You guys have given me a LOT to catch up on and attempt. I will probably start with Orion's timings posted a ways back for 7600MHz and see how it goes or if my machine will even post. DDR4 B-Die loved and scaled well with voltage, so I may need to go over the 1.435v limit.

     

    Also the system needs to be 120% stable as I run Linux for days on end, as a home server and as a folding box.

     

    I probably can't get an identical M-Die  kit as my wife just bought me the new EK Nucleus Dark AIO as well as a Crucial T700 1TB gen 5 m.2 drive. She was not thrilled with either purchase. Can't put them in yet as I just had a serious hip surgery and am only 3 days post op.

     

    Please keep up what you're doing though guys, rep all around as you are really pushing the limits of what's possible.

    samsung b-die is pretty decent, but anything beyond DDR5- 6600 is a pain! So if you really want such high speed DDR5 on AM5 you need a set of Hynix RAM, preferably 16Gbit A-die or 24gb M-die. If you cannot go passed 1,435v on your mobo i would just keep the Samsung kit, 6200C30 is nice, can you post a zentimings screenshot?

     

    How do you like the Nucleus AiO? I have one in my AMD rig its good far. sometimes the pump make a little rattle noise at a certain rpm, but its fixed now.

     

    image.png.1831779a95b62397434b8a9a81365b60.png this is what im running , with PBO -50MHz en CO 2 best cores -15 rest -35, for the hwbot teamcup. i cannot get 5000MHz otherwise

    I can't do much better on the Z690 Classified 😞

    How comes? indeed very weird i see another Z690 classified sub only at 125 bclk? My B760 board runs it at 145 bclk with DDR5-6800, is it the chipset?

  7. buildzoid videos are packed with info , really nice for a beginner!  The best source for DDR5 OC and stability information is ocn forum. 

    With 7800X3D and 8000C34 vs 6600C26 i have virtually the same fps, pyprime, other benchmarks etc , thats on a single CCD, i think the difference with dual ccd is even more, so i would personally go with 1:2 on every AM5 chip.

     

    Can you also use higher voltage on M-die modules? you only use 1,43v,  If you set 1,65v can you lower tCL and tRCD?

    would really love to see a max tight OC on 8000 with them! can it do 8100C32-45-40-32 at 1,65v for example? with tight subs? How low can you set RRD's? with 16GB M-die they do 4 4 

    and can you run yc or other RAM heavy benchmarks with it?

  8. Do you have any particular question about setting up your mobo settings? Or just everything from scratch? 

    First of all disable all CPU things like: 

    spread spectrum, global c-states, virtual machine(vt-d), core performance boost, also disable PBO completely

    all the voltages, frequencies, timings: for all of them, dont use auto settings but instead dial it in. i like to use the EXPO settings at first later you can tweak. 4x16GB Hynix M you can get 6200C30 in 1:1 mode but not Much more. That will be around 1,25v soc, maybe up to 1,55v vdd/vddq but chances are you can get away with lower voltages. For 1:2 mode, what is prefered with dual ccd chips, you can use 2x16GB and Maybe get 8000 to work but i have not tried Hynix M-die at those speeds yet.

    If you have any particular questions pls feel free to ask!
