What is the PSU that you are using?And just be enabling performance you are getting a boost?
For the moment, I have not yet had time to test it, but from what I know two people I know have tested it and have no problems and it even solved some stability problems they had with RAM overclocking compared to versions "'4.03.MEM01", "4.04" and "4.06", for the moment you are the first to come and complain and to encounter performance problems, maybe you should review all your BIOS settings one by one and by doing a "CLEAR CMOS" beforehand for safety...
4.03 vs 4.08. there is massive performance drop...
I tried to find that. 4.03 that was enable by default. Probably cause some issues for those who had stock PSU. I got currently have Innergie 180W PSU. If someone here have any connection to ASRock team. That option should come back.
From what I remember on the DeskMini "X300", some options and features were intentionally "hidden" by ASRock, but could be made visible again by doing the "Ctrl+Q" key combination in the "OC Tweaker" or "Advanced" tab, so try it and see... I make no promises
No secret menu this time. When vodka is giving me some peace (tomorrow) i will put that 4.03 back and try 4.03 vs 4.08 both "stock only XPM". This is driving me crazy. It is not possible that basic bios update will drop 3dmark score 30%. Hardware is same.From what I remember on the DeskMini "X300", some options and features were intentionally "hidden" by ASRock, but could be made visible again by doing the "Ctrl+Q" key combination in the "OC Tweaker" or "Advanced" tab, so try it and see...

Try with "4.04" and/or "4.06", to see if there is a difference, this would allow to discriminate if the problem is inherent to "4.08" or to all BIOS having received the AGESA 1.2.0.2a update (4.04, 4.06 and 4.08). But personally I think rather that it comes from "4.08".
If the bios have that Performance Mode that will tell you must have 180W PSU that is the answer. What that mode is really enabling ASRock will know that.
AFAIK the performance 180W option was just increasing some current limits. You can achieve the same by increasing them manually under Advanced - AMD overclocking - PBO menu (can't remember exactly what was increased, but I think it was TDC to 120A which is sustained current limit; I don't know if it was also increasing PPT which is overall limit in watts).
I just noticed that your new result is running 2,832 MHz average memory frequency (which translates to 5664 MT/s on average). That explains the lower performance.
Memory VDD (main memory voltage) mainly affect primary timings, and they are not very important in DDR5 anyway (DDR5 strong point is increased amount of bank groups vs DDR4), so you can run low memory voltage at expense of loose primary timings without much performance hit. This also helps with memory temps which could be a problem in the Deskmini.To tell you the truth i would prefer not to touch voltages,maybe i will try something like 1.25 and maybe close to 1.3 max...I don't feel comfortable going past 1.3
This is my bench with 6400 as of yet...So far i working with the, like 2 whole days to try and make them better lol
By the way, if you're going to run 2:1 mode, you should be able to run VSOC at much lower voltages, specially at that frequency. I'd give 1.05v a try and see if our PSU and VRM can handle it, that way you have more power headroom and less idle consumption.To tell you the truth i would prefer not to touch voltages,maybe i will try something like 1.25 and maybe close to 1.3 max...I don't feel comfortable going past 1.3

I managed to gain some performance with tight timings and increased Fclk not 1:1 but i pushed it as much as i could without producing errors.
Just SOC voltage. I wouldn't touch any of the other voltages if they're stable since you won't save much power nor gain performance by adjusting them.I managed to gain some performance with tight timings and increased Fclk not 1:1 but i pushed it as much as i could without producing errors.
Should i change the whole lot to 1.1 or less or just VSOC?
PS:I do run with a -40mv undervolt set by the bios.And i have the IGPU oce'd to 3100.I also tightened the timings a bit more and the BW did go just a few points up.I'm doing that for 3 days now lol I don't think i can do much more without touching the voltages.So i will settle with this at least for now.
PS2:My disappointment tho is that even with IGPU/CPU and Mem OC. In AC syndicate the gain is only 6fps from the aggressive 5600 profile...without any CPU/IGPU oc.
