pull 3 sticks and run

Things I've tried:
  • One stick of memory. Crashes both with my Corsair and G.Skill TridentZ.
  • Two different video cards.
  • Two different installations of Win10 on different devices. (SSD + HD)

The only parts I haven't changed are:
  • The CPU. (I only have one Ryzen CPU.)
  • The PSU. (I don't have any spare PSUs lying around and it's too much work to take apart my other builds.)
  • The motherboard. (I only have one AM4 motherboard.)

Temperatures are always below 80C. So I doubt it's a cooling issue.

can you take a picture of the bios voltages for me, namely dram dram termination and SOC

each zen thread is being registered as an individual core with its own L2 and L3 cache

I have a weird feeling that this and some other gremlins some are experiencing could be related......

OK the SOC voltage is preety damn low. It should be around 1.00 minimum and the range is 1.0-1.20 bump to gain stability.

The bottom voltage Dram termination voltage should be equal to 50%

The BIOS won't let me set an SOC voltage offset of more than 0.2. It puts a hard limit of 1.0 volts. Perhaps it can forced higher via the LLC settings. But I'm hesitant to put settings up the limit of what the BIOS allows.

I'll play around with that a bit tomorrow. But if what you say is true (SOC should be 1.0 - 1.2), and the BIOS number is correct, then perhaps ASUS is simply setting it too low to begin with?

I'm running high LLC and 1.00 SOC my board defaults at 1.1. I found in my case chasing highest clocks I can drop it .100 to drop heat.

For 4 dims populated yes that would be a tad to low by default imo.

My biggest concern is not your board but the report of the crosshair also exhibiting this issue. I'm under the understanding that they are working on updating mainstream boards second top tier first......but if ch6 has this issue..it should have latest agesa already.

you can try install win7 via iso with USB3 drivers inside (at web of Asus is in download section software to create bootable USB win7 with USB3 drivers)

Before I go through the trouble of trying out Win7. Have you guys tried running the benchmark? Did it crash?

(I'm desperately working to get the Zen tuning parameters for y-cruncher v0.7.2 in time for March 14. So I don't really have that much time to keep debugging this.)
