Intel's 200s Boost help

[Sniper101]

Hi all,

 

Hi all,

First up i have a 285k and G.Skill 8800mhz CUDIMM 2 x 24gb - 1.45v with Asrock Z890i Nova itx mb.

 

This won't work as i tried with XMP profile 2 = 8800mhz. Boost states not higher then 1.4v. It booted after 2 tries but with a frequency penalty of around 4600mhz. XMP 1 = 6400mhz will work. with 200s boost.

According to what i gathered there is a work around.

 

Enable XMP 2 then...

By lowering manually the frequency to 8000mhz

And lowering the VDD and VDDQ to 1.4v

Is this correct ?

 

How should i proceed with the steps i have general knowledge about BIOS setting but i am not a expert.

 

Right now im running Asrocks "extreme power plan" + XMP profile 2 = 8800mhz - 1.45v. I run multiple tests ie Memtest86 = PASS, Windows memory diagnostics = PASS, Prime95 (stress the IMC and RAM 1 hour) = PASS, OCCT large dataset Extreme Preset = PASS. Cinebench23 = PASS

Latency now = around 77 - 78ns

 

Should i just enable "intels default power plan" then enable xmp 2 = 8800mhz but lower freq to 8000mhz and lower both VDD and VDDQ to 1.4v (from 1.45v) then ENABLE "intels 200s boost" If this is correct the intels 200s boost wil automatically adjust CAS timings to that for 8000mhz yes? Or are the steps completely wrong? In that case what steps do i need to take and pls explain it simply from a Asrock BIOS standpoint.

 

Thanks in advance.
