DRAM Calculator for Ryzen v1.4.0 by 1usmus Released: Memory Settings Made Easy

[btarunr]

Ukrainian PC enthusiast and software developer 1usmus today released DRAM Calculator for Ryzen version 1.4.0. This utility was formerly known as "Ryzen DRAM Calculator," which has since been voluntarily renamed by the author in the interest of avoiding any future trademark conflict with AMD, or giving users the impression that the software has been made by AMD. The change in name doesn't change the fact this could be your go-to app to figure out the best memory settings for your AMD Ryzen-powered machine.

PC enthusiasts usually only remember 4 or 5 DRAM timing settings besides DRAM clock and voltage, letting the motherboard BIOS figure out the rest of the stable values, which could often be looser than needed. DRAM Calculator for Ryzen figures out nearly every under-the-hood timing, voltage, clock-speed, and other setting needed to make the most out of your memory overclock. You can also make the app work out "safe," "stable," and "extreme" variations of its own calculations. Version 1.4.0 isn't just a name-change for the application. It introduces a large number of critical updates to the app that improve accuracy and functionality.

The change-log follows.

• Initial support Threadripper gen 1 and gen 2
• Improved SOC voltage prediction for different processors and their generations
• Additional window that will tell what minimum DRAM voltage is needed by the system
• Additional windows that show a nanosecond delay for the current calculated profile. It will be especially useful for users who are reflashing SPD
• Improved prediction procODT + RTT + CAD_BUS for some memory (the block has endured many changes)
• Improved overclocking for Hynix CJR . Up to 3800 MHz inclusive. Big thanks @Reous for the help
• A switch has been added to define system tasks, BGS / BGSalt recommendations depend on it. Turning off BGS allows you to increase gaming performance by up to 5%
• The "Custom" profile will be based solely on the data that is placed in XMP. Its new name is "Debug". Mode designed from scratch, available for almost all chips (but still need some time for a more subtle configuration).I think this mode is needed for professionals who want to see all the changes relative to automatic overclocking or XMP profile. This will allow them to see some nuances that can not provide the profiles of "V1" and "V2".Also, this mode will be useful to owners of systems based on Intel processors.
• Some changes in procODT + RTT for systems in which 4 RAM SR modules
• Added support for Micron D-die
• Changes in the code that will help speed up the development of the calculator (future versions)
• Added some popup tips for key settings
• New picture in folder Configuring Ryzen Systems v5
• Other corrections/bug fixes

Thanks for posting this.

The problem is buying ram, its impossible (Unless you buy expensive ram) to know which die you get, are there other dies than samsung b-die that is recommend for Ryzen?

You can see from the frequency/timings what the chip is. For example all 3200Mhz CL14 are B-Die as are 3600Mhz CL15 (very rare) and CL16. Also anything above 4000Mhz are usually B-Die.

There is a new kit that popped up by Kingston that is using Hynix chps and is pretty good value. On the surface it's bog standard 2933Mhz CL15 but it overclocks very well to 3600Mhz or even 4000Mhz with decent timings. Also it's cheaper than G.Skill/Samsung stuff: https://geizhals.eu/kingston-hyperx....html?hloc=at&hloc=de&hloc=eu&hloc=pl&hloc=uk
and 16GB: https://geizhals.eu/kingston-hyperx-predator-rgb-dimm-kit-16gb-hx429c15pb3ak2-16-a1812967.html

I know the 3200CL14 is b-die, but all those are 1750DKK here in denmark while the cheapest 3200CL16 is 1150DKK so a pretty big difference, the kingston is 1450 which seems okay if it overclocks well, do you have a link to a test of that Kingston and overclocking of it?

It helped, but I still didn't managed to get my Hynix chips to 3200... 3133 seems stable though.

Edit: Unfortunately it's not stable enough for gaming

Check and be sure your Mobo BIOS is fully up to date. Mine would not run at rated speed on my ASRock Taichi until it had BIOS revision 3.00 or newer.

I was able to reach 3000 at 14-15-15-40-60 , Voltage : 1.33v , Hynix M- die ( DDR4 3200 Cl 16-18-18-38-56 , G skill F4-3200-C16-8GVKB) , Latency is now 77ns.

Sadly it is. Asus has been quite hit and miss for my RAM, despite it being on their list of certified modules.

 

[Schrodinger's Bodybag]

Didn't even know this existed, thanks for the post. Up until this point I was convinced to be condemned to 2666mhz on Ryzen.

 

[TheoneandonlyMrK]

Worked well for me to improve my timings, things are more stable and smoother , my Corsair vengeance rgb 3000 but is at cas14, still wouldn't hit 3000 but fast 2933@c14,16,16,16,28,38 will do, for now

Can someone get me a question?
I have a Msi motherboard x370 games pro carbon, and it seems to me that it uses memory routing (T-topology).
According to master 1usmus this topology and inferior to daysi chain for memory overclocking.
Well: I have memories 2x8gb gskill royal 4000 cl17 b-die, and I will get the new ryzen 3700x.
I would like to know if it will be possible to reach 3733mhz with this motherboard, in the BIOS of it has option until ddr4200.
Would this T topology limit me to 3733 sync with the 3700x?
Will I have to change my motherboard for an x570?

Yes i think you can achieve 3733 on that board. Ryzen memory overclocking is more dependant on the CPU and memory itself and less on the motherboard. Besides 3733 will be the highest speed where Infinity Fabric runs at 1:1 speed with RAM. You can get higher RAM speeds likely but that means 2:1 ratio and half the IF speed so not a good idea except for some memory bandwidth intensive benchmarks etc.
