-40 across the board here with my 7800x3d on a gigabyte 670 elite ax. -50 is a bit temperamental.
tried the asus AI tweaker once on my old x470 rog board and it caused nothing but issues, usually the AMD bios options for tweaking are better if you can -
do you have the option of pbo enhancement?
so 80 126.96.36.199.5 90 188.8.131.52.5?
should be in the bios
set pbo to auto and try working your way down the enhancements if they are there,
on my board I use 90 level 4 - which is 90c target -40 CO outside of stress testing it rarely gets above 80c.
Found these mem timings also work fairly well for 6000 expo - rock solid.
Thanks for your input, I'll give it a go.
New bios update is out. It seems just a 8000 series support.
"Update AGESA version to Combo AM5 PI 184.108.40.206b"
Even though 5700x3d is a nice cpu you can clearly see v-cache isnt helping in games that like memory bandwidth performance do drop off compared to ddr5 zen4 cpus.
OK guys I need some help with my MB and overclocking. I can get my ram to 3200 and pass no problem without messing with the other voltages other than SOC and DRam voltage but anything higher it won't hold. I've got the Asus CH VII x470 & 5800x & Flare X B-Die CL14 Ram. If I were to try 3466 give me a ballpark of what these voltages should be. VDDIO Voltage Control / VTT Voltage Control or VTT Memory Value / VPP_Memory Voltage and VDDP Voltage / and anything I'm missing? I've been beating my head against the wall for days and can't seem to find info on the Web either. Thanks I appreciate anyone plz.
Post a pic of zentimings.
Do those voltages need to be messed with in order to get higher? Or is it just SOC and Ram and leave rest on auto?
the timings are no big I've tried very loose for 3466 and I see peeps getting 3600 and 3800 with b-die. And 3600 with 3200 timings.
I'd be thrilled with 3466 and a nice low latency hell I'd be happy at 58ns. Just going by what I see others getting.
Here is one I'm trying to get going with 3400. the SOC is actually 1.10 when running... lvl 3 and 120% 1.40 ram.
Here is what I'm running @ 3200 with 8000% pass @ SOC 1.10 lvl 3 @ 120% and Dram 1.35.
Really no help?
Start by setting the memory to 3800 and the IF to 1900. Set loose timings, basic JEDEC.
Just to see if your IF can support such speed. Most Zen3 do.
Your voltages are a bit high. But you can try to lower them later.
I have my memory at 3800 with 1.39v. But I don't know if yours will be able to do such speed with such low voltage. Use 1.40v to 1.45v then try to lower it.
I think you have samsung B-die, so it can take voltage very easily.
One thing you might want to do is set your ProcODT to 40. This improves signal integrity.
The conclusion is that core count does not really matter only cache capacity and core clock does.
