Question 2nd Gen Ryzan RAM OC Issues

[MrThankUvryMuch]

I'm new to overclocking and have been doing some research. From videos and forum posts I've seen, I should have no problem bringing my RAM speed from the stock 2133 MHz to it's rated speed of 3600MHz. This is not the case for me. I've been through 3 sets of completely different RAM for reasons unrelated to OCing, and they've all given the same results. My system will post in safe mode or crash a LOT if I try to OC the memory past 2866 MHz. I have no issues OCing my 2700x.

I have my CPU OC'd to 4.1GHz for now, which is stable with 2866MHz RAM speed at 1.35V. I've tried running my RAM at 1.36V at 3600MHz to no avail. To get my RAM to 3600MHz stable, should I increase my RAM voltage more? Or what's my issue here?

The 2700x doesn't support 3600mhz memory...the official supported speed is 2933mhz...anything above that is silicone lottery luck. My 2700x would run all day at 3200mhz cas 14 or 3400mhz cas 16...anything above 3400 regardless of timings was not 100% stable. I was using expensive Samsung B die memory.

The 3000 series Ryzen chips have improved memory controllers and most will handle 3600mhz or more.

Not true, it's limited only by BIOS and memory itself. My 2700x run 3600MHz Cl 16 super fine. I even got it up to 4000MHz but with so high Cl that it actually lost performance.

Did you set DOCP ?

Then you won the silicone lottery plain and simple...the memory controller is located on the chip and the officially supported speed is 2933mhz. With the best Samsung B die money can buy mine wouldn't touch 3600mhz...3400 was it.

Then I better buy some real lottery, 1600x, 1700x, 2700x and 3700x on 2 MBs, all working with RAM way over that IMC barrier ?

Maybe you should grab some real lotto tickets 🆒...the 1600 and 1700's were both notoriously bad at memory OCing...granted that was mostly due to BIOS issues. I never bought a first gen Ryzen mostly due to those bios issues...i waited for the 2700x to roll out and I was pretty happy with it hitting 3400mhz although 3200 @ cas14 was faster than 3400 @ 16 so that's where I ran it.

Im planing to buy 3200mhz for ryzen3 2200g u say it wont run with docp mode ?

It's all about BIOS, AGESA and topography for memory on the MB. First 300 series MBs had different/ wrong topography and had problems with RAM over 2933/3200MHz which are both over purported IMC limit. Sure, it took Samsung b-die to get over 3200MHz but was doable by manual RAM OC.

Before i upgraded my cpu to the 3600x I had my 2600x and g.skill trident z royal gold 2x8 cl16 3600 16 16 16 16 36 running @ 1.45v
With docp 3600 freq 3600
Proc 60
Rtt nom off
Rtt wt dynamic off
Rtt park on auto
And the 4 cad buses set to auto.
This was on the Asus rog strix x470 f gaming bios version 5406, with a 4.1g Oc.

The 2000 series bios was way better for ram then the 3000 series running a 2000 series cpu.

Now I'm on the latest bios 5220 for my rog and 3600x with my royal gold rated for
16 16 16 16 36 @1.35v running
@ 3733 fclk 1866
Set @ 15 15 15 15 30 45 @1.35v

Hope the proc and rtt's help!!!
