Ram OC with DRAM Calc

[CombativeToaster]

Ok UPDATE***********

 

I now have 4 of the sticks below XMP still not working and ran through the setting below, not sure what the heck I am doing wrong

Use A-die mode then? It's generally the worse one.

tried that still not working =(

Gonna have to kick the memory & controller in the butt once.

 

Set Memory voltage to 1.410v

Set Cpu SOC to 1.175v 

Set Power Down mode to disabled.

Set XMP profile, but manually set speed to 3200mhz (or w/e it'll post at highest speed for you)

If it posts 16-19-19-19 at 3200, see if they all will do 3200mhz at 16-18-18-18. 

Set command rate to 2T CR.

 

The calculator is useless for running mixed matched memory. Unless your using one kit or the other, don't bother with it.

Don't worry, the Calculator doesn't work exactly that well with my setup either. It's pretty close, but it doesn't just "boot right up" with the settings it gives.

The reason you set XMP profile and then set the frequency lower is so that the XMP profile sets up the sub timings for higher frequencies for you. You shouldn't have to change anything at a lower speed while the sub timings should be relatively loose enough to do so. 

 

I train my memory sticks by starting low and working the way up frequencies and testing. lots of testing. Once passed to my liking, I'll increase the frequency.

 

Don't worry about the memory voltage. 1.410v is nothing short of a minor over-volt. You can do 1.445v if need by. My only advice is to actively cool the memory with a fan directly on them sticks. All for the better, running cool helps stability.

 

In the end, you may not see 3600mhz with those 2 kits of memory together. Don't let that shake you. If you can run the 3200mhz say Cas 16 or better yet Cas 14, you'll have lots of performance gains over that stock 2133mhz CL 20 for sure for sure.

 

Dig it? Trial and error, if 3200mhz still doesn't post, aim lower. But I think those kits might do 3200mhz. It really depends on the Ryzen memory controller. How picky is your going to be today?

I agree with the above post but you should be able to use the worst kit and apply those timings to the samsung die too. 

I'd also set the Dram to 1.4V and SOC to 1.15V to start make sure you set ALL the timings and what i have highlighted, if 3200mhz fails drop down frequency and keep these timings until its stable or increase voltage on memory to 1.425V

First things first.

Rule of thumb. Single stick OCs the highest.

Dual sticks 2 x 8 B-die high end clocks the best. (high frequency memory)

Quad sticks just gets the heavy on the already picky Ryzen memory controller.

Then the age old "Don't mix match memory" for a reason. Those sets of sticks are probably on different PCB layout, for example one maybe A1 PCB and the other A2.

 

Oh there's so much to memory and just getting it right...... The poor under-informed people in the world. (not you, just the Ryzen memory issues people have here, there are many)

Hey i agree i pretty much love tweaking memory in general and now a days that's where the gains are. 

 

I bought a high binned samsung B-die when Ryzen first came out as i plan on using it with each gen that comes out. So far i got 

 

3066mhz with 14 cas timings on my 1700

3466mhz with 14 cas timings on my 2700x

3800mhz with 14 cas timings on my 3700X 

 

All on the same X370 taichi too! Mainly thanks to that wonderful program i have to admit it taught me a lot and that's how i got started. I spent SOOO much money on this kit of memory though but i wanted something fun to play with haha. 

 

I haven't mixed different types of memory on a platform since the original Athlon 64 days

My 3600 B-Dies are running 1866mhz CL 16-16-16-36-56 2T 2700X

The Other B-Dies G.Skill 4266mhz @ 2150mhz CL-16-16-16 2T  (Benching stable) on Intel 8700K.

(Effective clocks)

There's a difference in Ryzen memory controller and Intel's Big difference.

oops double post

yea i didn't notice that there where made differently, i bought what i thought was the same RAM but i think i am gonna pickup a second of the same kit and make sure they match but ill try these out and see what i can come up with, thank you !
