X370 Taichi PCIE freq

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   So, when I leave the 'OC Mode' setting to auto A-tuning shows my pcie freq as 273Mhz, if i set it to manual and put 100mhz, it shows 100mhz.
I thought auto would keep it to spec? Should i be manually setting it.

Stable in prime95 with it set to manual 100mhz.

Ryzen 7 1700 @ 3.8ghz, vcore 1.3, SOC 1.2

	mine stays stable at 100 mhz, to be honest at 273 i would expect it to crash , maybe its a false report ?

	I assumed that it was just an error but I wanted to check if anyone else was experiencing it. I reverted back to 2.40 bios and at auto it stays at 100mhz with the same overclock.

	THAT is an error in this BIOS rev/AGESA. What BIOS rev is this with please. I'll report it. My understanding of this is your memory is set using XMP, which set your BCLK to ~129 yet left the PCIe Lock "open" Please, PLEASE, PM me or reply here with the BIOS rev this is occurring. Sincerely, wardog

	lupercal15 Please reset your BIOS and look at and reply back what the BCLK is set to.
