[Help Reducing Memory Latency 4133 15-15-15-30 2T (can't break AIDA64 50 ns)]

Thank you for your response @wutske. Much appreciated.

It seems from my testing that my board won't allow 1T a this high of a frequency (4133). 

I did have 1T running previous with with following frequency and timing: 

Frequency: 3600 MHZ
Primary timings: 14-13-11-21

Perhaps I can revisit 1T and try going up from 3600 with looser timings. Thanks for that suggestion.

And thanks for catching that reduced BCLK. I hadn't researched that frequency before, and now I see that drop from the 100 MHZ set in bios.

And now I know what "spread spectrum" is and what it does. 

I tried increasing by .24 to make up for what was missing, but experienced instability. I did not however try disabling Spread Spectrum.

I did see a slight increase in RAM and CPU frequency from that increase. I guess that's how people are able to get those non-standard RAM frequencies I see online.

I did order a z790 Apex and some 8000 MHZ DDR5. I bet THAT board will allow me to play a little more with BCLK with better stability.

I just don't know what else my z690 Edge can give me.

Thanks again, and let me know if there's anything else you think I can try.

Hi all,

Long time gamer, first time poster.

I've been fiddling with my RAM timings for for days, and I don't know where to go from here. 

Thought I'd see if someone in the Rookies thread can help me out.

My goal is to get my latency (AIDA64 Extreme ) below 50 ns, I dream of 45-46 ns. But is that just what it is? A dream?

Current AIDA64 Latency ~ 51.8 ns
Stable at 4133 with 15-15-15-30 RFC 260

Specs and OC

 

(TestMem5 anta777 5 Cycles PASS)
(secondaries and Tertiaries are in the screenshot).

Kit: GSKILL Trident F4-4266C17D-32GTRSB

RTL : I thought I had tightened the RTLs, but it looks like I only have them at 73/73/73 | 81/81/81
(Can't find iO-L timings in my BIOS to fiddle with them) 

Board: z690 Edge DDR4
VCore: 1.325 v
DRAM Voltage: 1.5 v
SA Voltage: 1.42 v
VDDQ: 1.35 v

What can I do here to make an impact on my Latency?

Hope I've provided enough info, and hope someone can give a guiding hand.
