B650 PG Lighting + 8500G memory questions

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

   Hi Asrock,

Curious to ask a few things about this motherboard and CPU combo. I?�m specifically interested in combining it with Gskill 2x32 kit, specifically the F5-6000J3636F32GX2-FX5. I?�m on the latest 3.25 bios.

Questions:

1. Per this post https://www.overclock.net/threads/expo-profile-doesnt-work.1816289/?post_id=29467023#post-29467023 I was unable to POST with EXPO settings as the board seems to set bad override impedance values for ProcODT and RTTs. To get it to POST I just had to set these values back to ?�Auto??after enabling EXPO. While this kit doesn?�t seem to be on the QVL (it?�s on the B650E QVL though I think), this is still odd behaviour isn?�t it. Why would enabling EXPO change impedance from Auto? Is this something that should be fixed, as I imagine it will catch others?

2. I?�m looking to tune this memory and can?�t see any setting for ?�Tcke??in the memory timings. Why isn?�t this exposed?

3. For some reason, ?�Tphyrdl??which I beleive is trained (not usually exposed to user to set) is training at a high value of ??6??with my CPU. Yet someone with the same kit and board is getting a much better ??6??(per the above post). Why is this? Shouldn?�t the 8500G be training the same kit on the same board at similar settings when simply turning on EXPO?
