For us Ryzen boys
Ryzen DRAM Calculator 1.3.0
changelog:
* added initial support Hynix CFR (18nm), Micron E-die (16nm)
* substantially reworked most of the presets (timings, procODT, RTT, voltages)
* the "custom profile" now works a little differently, in most cases the XMP data is simply not compatible with Ryzen, so some timings are calculated according to a special algorithm. My opinion, importing a profile in most cases will not be successful anyway, AMD and Intel controllers have huge architectural differences and signal tolerances.
* combined Samsung e-die / d-die (v1 profile d-die, v2 - e-die)
* Extreme preset got a new life (I remind you that any memory requires additional cooling, if the memory heats above 52 degrees the system loses stability. AMD I have notified.)
* Overclocking potential DRAM is back for samsung b-die (for other chips, support will be added later)
* the combination for procODT + RTT now has more accurate recommendations for frequencies, with a change in frequency, these parameters change
* some items have been removed (for example, the recommendations have become smaller, DQS str + Data drive has been removed because most motherboards do not have these settings. These settings work only on ASUS CH6 / 7)
* new AGESA brought some changes in the power supply (PMU) for SOC / DRAM, the difference between generations of processors I did not see, because the choice of processor generation was removed
* appeared protection from stupid situations, when memory is not capable of working at the desired frequency, but the calculator gives suggestions
* added Help tab with 4 button (Overclocking Statistics + Information support)
* in the folder with the program now there is a picture, it is a methodical tool to help you set up the system

news and some important information:
A huge amount of time was spent on testing, because of this I had to delay the release of the new version. There is a problem you need to know about. Timing tFAW in most cases does not have a fixed time, the rule tFAW = tRRDS * 4 does not work, this timing must be selected manually. For example, 3666 I have stable only at tFAW = 27, and 3333 at tFAW = 17.
There is also a nuance, not all motherboards of the X470 generation received a new bus topology. The difference is in procODT, for example 3666, I can make it work with procODT 48, but some cards require procODT 60. In case of failure, you need to check the neighboring values of procODT.
AGESA 1.0.0.4c has an improvement in DRAM overclocking, at the moment AMD strives to ensure that most of the key settings work perfectly in automatic mode. First of all it concerns CAD_BUS. The values 24 24 24 24 are relevant for single rank. The release of the final bios is scheduled for the end of July.
At the moment, AMD has provided the developers of motherboards with a new AGESA 1.0.0.5. In addition to the Specter 2 patch, it is not known what it provides yet.
