Other new test today.

I finally updated the bios , test the ram at default xmp profile (3600), and again errors in memtest and bsod, nothing happend with the bios updated, all the same as the previous version.

But I put the ram in 3400 17-17-17-37, and everything run flawless, 0 errors in memtest, no bsod, and aida 64 stability test for 15 minutes no hardware errors.

For now i keep this settings, until new bios arrive.

Thanks for the help.

you should be aiming for lower timings than higher clocks 

which is why you see i'm on 3333 14 

so far sweet spot seems to be 3200 14 for others

XmanSE, did you set ALL timings manually in BIOS? Leaving them on AUTO may be the cause of errors. Use Ryzen DRAM Calculator.

Just to update my situation from previos, on X370 Taichi- raising DDRV (1.41V) & SoCV (1.625) like suggested and LLC 4 -  didn't help, another BSOD -  Memory management.

Just got to 3 days of uptime, it was all going smoothly and then in the middle of usage - boom.
I AM FURIOUS!!!

I am also afraid that new UEFI update (with 1.0.0.4) won't bring any improvement (hope in next 2 weeks, C'MON ASRock) reading others' experience with Agesa 1.0.0.4 UEFI on X470.

This is never ending nightmare!
Cx5 - UEFI screenshots, pretty please.

Sorry, I meant 1.1625VBig smile So mad I fried my board, not yet.
I just got beta 4.72 BIOS with AGESA 1.0.0.4 from jzelectronic.de, but I will wait 2-3 days until I try it (set tRFC, 2 & 4 to Auto now, also set ProcODT back to 60 Ohms from Auto in last try)...until next BSOD.
They (ASRock) will probably put unchanged version of beta on ASRock Support BIOS page.

Yeah, DRAM calculator didn't do much for me since last 2-3 versions of BIOS & 2700X.
I didn't have errors in Memtest before these BSODs, AIDA64 memory stress test for hours is also fine, OCCT too.

That's why I am crazy, it's all OK in tests, but after 3-4 days BSOD with Memory Management. I'm boring with this even to myself...

Yes i know, but my ram is not as good, because in 3400 cl 16 system won´t boot. The defaul values in xmp for my ram are 3600Cl 19-19-19-39, 1.35v

So i think for my ram, this is the best that i have for now.

I enabled the profile, then set the first timings manually 17-17-17-37, i did not change the others, only those.

Thanks for the help

You definitely don't have B-dies, so if your RAM is 3600 C19, then 3400 17-17-17-37 is really good.

As it was already mentioned here and in other threads - if RAM has 3600 or 4000 in XMP, does not mean that Ryzen will accept it ;) Besides your MB supports max. DDR4 3466, so 3600 is just unsupported ;)
