How influence high soc and other voltage o temp cpu, not cpu voltage, just wonder?
Oh good! So you are able to boot with 1900fclk in coupled mode with RAM! Great! Perhaps there was some other setting in your mobo that was affecting your memory oc
Yes, the calculator gives rather optimized timings for lowering the latency, making performance at the same speed even better.
So you should see better numbers when punching in the calc numbers. Remember to test for memory stability in between entering changes from the calculator. Like maybe 4 at a time and run an Easy pass of Memtest on the calculator itself of 50 loops of Memtest64 or what have you, just to give you a base line of stability. If it fails quickly go back one step to find out which value it didn’t like.
Once you get to all the numbers on the calculator, then do a looong pass. Like 200 loops of MemTest64. I’ve found that one to be rather effective. The new MemTest from the calculator is also good and it gives you bandwidth and latency numbers like AIDA.
Speaking of testing... for the sake of consistency and ensuring you are seeing improvements in your Memory tuning not being affected by anything else, set clock speed to a fixed value. Nothing crazy, like maybe all core 4.0 or 4.1 ghz. If the cpu is doing it’s auto clock fluctuations all the time, your bandwidth and latency numbers will be different every time and you want your numbers to only be affected by your RAM settings. Also go to Task Manager and on Startup Tab, disable any unnecessary software, this is for the same reason. Once you have memory where you like it, or you are done for that day, then enable CPU Auto Clock or PBO or however you had it before, and the rest, enjoy and continue later
This is going to be consuming for sure.
