I got X370-Pro replacement yesterday. My first board came with 0502 BIOS, 2nd one with 0504.
As I mentioned in other thread:
- 0502 was giving me lower CPU temps and I mean 5-10*C lower than 0504 under full load
- 0502 has additional memory timings but I don't know if they're working, most motherboards have only main timings
- There will be new BIOS if not 2 in next days. New microcode was already released and some boards like Gigabyte B350 already have it
- To run memory at higher frequency you need single rank/single sided memory modules ( no more than 2) and set higher VTT voltage what also requires higher memory voltage, in my case 3200 is fully stable at ~0.9V VTT what means that memory has to run at 1.40V even though it can make it at lower voltage
- As AMD said max real temps on 1700X/1800X are 20*C lower than what software is reading, so when you see 80*C then it's 60*C in real ( I have no idea why they set sensors like that as it's causing fans to run faster and make more noise )
- 3.9GHz on my 1700X requires 1.35V, 1.35V is stock voltage but stock is actually 1.25-1.40V on these chips
- LLC1 gives the best results ( voltage is close to what I set manually, about 1.35-1.37V when I set 1.35V in BIOS ), however when you set higher voltage then voltage difference is higher under load
That's all for now
