Wonderful_Greg Hello everyone.
I have a couple problems with my setup. One is just strange, and another one is super weird.
Was hoping kind folks in this thread could share their wisdom and experience on the matter.

I have a CH6 mobo + 2700(non X) CPU and ever since i got it(about 6 month ago), i couldn't get my system to work stable at 3200Mhz memory settings and above.
First, I`ve been using Corsair 3200 kit (Hynix AFR chips). And system just crushed after a minute or so after boot with 3200 setting. I tried XMP, manual, timing tweaking, memory voltage boost. Nothing works. As soon as I set 3200 MHz - system starts crushing. 3133 and below - and everything is super stable.
At first, I thought I just got unlucky with memory kit.
Few days ago, i decided to switch to HyperX Predator HX436C17PB3/8 (2 sticks). It`s a samsung B-die chips(K4A8G085WB-BCRC), high speed, mediocre timings and good price for a b-die.
The thing is, with these sticks problem remains the same. Anything above 3133 - unstable within minutes. Difference is, on Corsair kit - system hang completely. With these new - only application crushes.
No matter what timings I use, what voltage, CPU overclocked or not - it will not work above 3133.
For now, using memory calculator, I set everything 14, 14, 14, 30, 44 with 3133Mhz (1,36 volt) and everything works fine. but still. It should work above 3200? Right?

What could cause this? Really unlucky memory controller? Maybe faulty motherboard? Have any one experienced something like that?
I do want to switch to 3700x eventualy. But desided to wait a litle for more feedback and stable bios.



And on top of that, got a really weird one too.
These new stick I use, have issue i have never heard before and could not even google something similar.

Whenever I set CAS to 15 or 17(manual or XMP, does not matter), after reboot it always sets to +1. 16 and 18 accordingly.

It only behaves like that with 15 and 17. With 14, for example, or any other number, everything is set correctly.
Is it a bios bug? Right now I`m using 6903. Still waiting for something stable above that.



Thank you in advance for your comments and replys.

Then i noticed that in Bios and in Windows with HWiNFO64 the voltage readings are off from the voltages i manually inputted. Is this normal? I searched the forum and the net but i found mixed answers.

CPU SOC Voltage Manual: 1.1 Reading: 1.11
DRAM Voltage Manual: 1.2 Reading: 1.22
1.8 PLL Voltage Manual: 1.8 Reading: 1.853
1.05V SB Voltage Manual: 1.05 Reading: 1.035
Perfectly normal, superio chip's ADC accuracy is just not that high. It has around 22-44mv stepping depending on the sensor

Guys, I'm afraid its never going to happen where you can brag about your CPU running on CH6 100% stable since this uncertified backward compatibility is not without problems.
The only issue with new cpu's (For me and my experience) is the boost and the cold boot issue (the reboots and etc), and even then the boost doesn't work correctly on the x570 for most people due to agesa or **** silicon, and yes it's placebo that your games feel smoother, and no zen 2 is not built on x570 chipset exclusively, and yes my cpu is running 100% stable on my CH6, sure the board has it's issues, but it's one of the best x370 motherboards and was overkill for it's time, you should have gotten a 3900x and keep the x370 tbh, but everyone's choice, I'm glad you now don't have any problems, enjoy your new rig

My cpu and memory runs perfectly stable. I never had any error codes or boot issues (or issues with this mainboard at all) It run smooth since the first bios with ryzen 3000 support. But sure, buy something new if it brings you peace of mind.

hwmonitor is not reliable on this platform. Your CPU never got to 6.8GHz



Use hwinfo, or ryzen master.

Nice! Which motherboard did you get.?

"Your mileage may vary." Glad you like your new X570. For me, there have been no issues to solve on my C6H, it has been a very smooth transition to my 3900X.

Addendum: I did have a weird problem with the Corsair Strafe keyboard refusing to let me into bios. It seemed clear that something in the keyboard was screwed up, so I replaced it with a Steelseries Apex 7 TKL. Problem solved and I was able to get rid of that darn iQUE software!
