Help overclocking Ballistix Sport 3000MHZ Cas 15

Hi All,

Fairly new to overclocking, need some assistance and guidance.
My Setup is below

Board: Gigabyte X470 Aorus Gaming Wifi 7
CPU: Ryzen 3700X
Graphics: MSI Ventus RTX 2080
Ram: Ballstix Sport 3000Mhz CL 15 (Micron E-die)

my issue is I can play around with the timings and all in advanced memory settings under BIOS except changing the Profile DDR Voltage which is greyed out. I can change the DRAM voltage under advanced voltage settings but then the Profile DDR voltage remains the same (1.35 if i choose XMP and 1.20 if XMP is disabled). I have contacted Gigabyte and they dont know. Disappointing really, this is amongst their top boards and yet it has these issues.

Am I missing anything? Is there any way to manipulate the Profile DDR voltage. I am trying to overclock my memory to around 3600MHz cas 16 (per the overclockability potential suggested by the Ryzen DRAM calculator).

Any and all help is greatly appreciated.

Thanks

Some BIOS could change v by typing a number or with the + - key but not by pressing enter to select a value, not sure if that is your issue?

Uhh, Profile Voltage means what voltage THE SPECIFIC XMP profile uses... Nothing more.

I cant even go to that line. Its greyed and is skipped.

So changing the DRAM voltage under advanced Voltage settings is the one then?
If i Disable XMP and change the DRAM voltage it still shows as 1.20v which is the Mobo default.

yeah I'm pretty sure it's under the advanced voltage settings. But Micron Rev E for the most part usually likes voltage and doesn't seem anywhere near as temp sensitive as B-die is and Rev E in general is much easier to drive than B-die just by the way it's made on the IMC/UMC side. Basically it doesn't like tight TRCD or TRFC other than that it's pretty similar to B-die and I'd suggest upto 1.5v for daily usage (since 1.5v is what JEDEC validate for as maximum). What you could perhaps try is auto the timings and up the frequency until you find the limit then tighten from there. Obviously if you get around 3600+ please be aware of the IF potentially becoming uncoupled unless you set it properly in bios, I'd recommend staying in 1:1 mode for the best latency/memory bandwidth. (Where the UCLK/FCLK/MEMCLK are all equal).

Thank you for these useful insights.
How would i be able to tell if I have uncoupled the infinity fabric clock versus my memory?


thanks again.


Edit: NVM, I think you have answered it. If say it is uncoupled, would increasing FCLK help?
