Imprezzion Quite simple. CL is purely the amount of clocks it takes to do a certain action. 3000/12 is 250, 4000/16 is also 250. So both actions take the same length of time (8 nanoseconds). This of course ignores all other timings except CL but it's a very rude but correct base calculation. If you cannot get at least CL16 on 4000 it isn't worth it latency wise compared to 3000 CL12.

How did you calculate this?

Are you saying that I can just flip primary timings, without any adjustments on other timings to make it work?

What I am looking for is something within 10% of 3000/12 latency if possible at higher speeds but I am not going to take higher speeds with such a big latency hit.

Do you have settings e.g. to make 3200/13 work?

Imprezzion 4000 CL16 is identical in base latency to 3000 CL12 not counting the secondaries. Try if the sticks will at least do CL16 at 4000 or even CL15 or 4200 CL16 as that would be an improvement.

As a quick and dirty test, Use Nizzens voltage settings but with 16-19-19-39-500-2T on 4000 or even 4200. If it doesn't go, DRAM voltage up to 1.5v, if it doesn't go, 1.55v, stop there, raise IO/SA to like, 1.30v, If that won't do it, it simply isn't going to run CL16 at a useful frequency.

If any of this does at least boot windows without BSOD or freeze, go down to 15-18-18-38-400-2T and try again.

Try to copy others results too. Just go back 5-6 pages and look for settings

Again, Gene and Apex boards... not even fun anymore.

If you follow a guide like the one in my sig first you can then tighten up tRFC and raise tREFI if desired to get better aida scores

Thanks munternet so started with your guide lowered a few things went from 43..7ns to 41.6ns which is a good start I think. I'm working slowly on secondary right now , passed memtest pro 1600% with memory temps not passing 43c. My vccio and vccsa still low some im running great temps. going to work on trrds and trrdl then tfaw
