dgoc18 2T is okay, 2T is for high memory clocks. There is nothing crazy about 1T at all. I have to accept 2T that works for me.

Mine ram 3800 IF 1900 2T 15-15-15-15-36-50-260 better than nothing, 1T won't post, I have to reset clear cmos every time.

Great information about Dram for main and sub timings. Link at below.

2 cents.

oreonutz I just re read the Rules and Realized I was supposed to use HCI MemTest and the Google Stress Test for this, not just Karhu Mem Test, so I now Realize this won't count, but I worked so long to get these results. So I am posting them anyway! LOL! I will run the other 2 tests while working today and post those later.

3900x - All Core OC 4225Mhz - Ram: 3800Mhz - IF: 1900Mhz - CL: 16 - tRRCD: 17 - tWRCD: 16 - tRP: 17 - tRAS: 34 - tRC: 56 - tRFC: 364 - CR1

Spoiler!

1T fail, 2T go...so I think it is clear

VPII 1T no go.... failed Karhu memtest at 2500% or there about so I'm back on 2T. Seriously it seems most people have this epiphany about 1T that they don't really see how to bypass it with other timings which works at 2T.

Because with my board I have no control over geardown and if enabled which I cannot see then I am sorry performance will be the same as 2T with geardown disabled. Okay, seen that Ryzen Timing Checker does not work I checked with AMD Ryzen Master and it is disabled so all good. Currently running Karhu Memtest and if okay for 5 to 7 hours then this will be my new settings.

my 3733 with 1T/GD enabled.


Especially for you.... 1T / 1N.... And tah dah.... it is exactly the same as with 2T.... I have now Geardown option in my mobo except that it is select able when choosing 1T or 2T it is a third option.

Indeed, AIDA memory benchmark is one thing but certain setting changes might increase your AIDA scores whilst reducing performance in some real-world scenarios.
