X370 F. Pro Gaming vs X399 FPG -- worse RAM compat

one side of me says logic should dictate board maker to adopt the same lessons and code over to TR
and for it to be easier to get ram working

but
with the TR your now trying to get 4 channels working instead of 2

the old adage applies more strain on a memory controller less ability to get the speed up

i know its not helping but your problem isnt going to be a lone one ,everybody using TR will want to be using the 4 channels and have it working well

the old answer again ,it should improve with later bios

SoniC and datonyb, I opened TR BIOS 1.50 with a hex editor and was amazed to see the following:

AGESA!V9.ThreadRipperPI-SP3r2-1.0.0.3

I was wondering if it was 1.0.0.6a or b, but if I believe what I see, it is 1.0.0.3!  I do not know if TR is on the same counting scheme, but if this is truly 1.0.0.3, I think it fixes fma3 bug but does not have the memory fixes.  I hope some ASRock person will respond (ASRock_TSD??).  Enjoy, John.

EDIT:  I sent ASRock_TSD and PM - will see what happens.

Thanks, SoniC.  The TR BIOS page says this for BIOS 1.30:

Update "ThreadRipperPI-SPr3-1.0.0.3"

I guess this should not have been a surprise to me.  I PMed ASRock_TSD once before on a problem I had and never got a response.  Google also finds 1.0.0.3.  Enjoy, John.

I own two Systems -- - one with x1800 on AM4 socket + X370 Fatal1ty Pro Gaming + G.Skill Ripjaws 5 64GB (16GB x 4, CL14, F4-3200C14-GVR)  - the other - Threadripper x1950 + X399 Fatal1ty Pro Gaming + same G.Skill Ripjaws 5 64GB (16GB x 4, CL14, F4-3200C14-GVR) The problem: on AM4 platform after the first beta AGESA 1.0.0.6 the RAM is basically set XMP, 2T, Geardown disable and forget. Flawless. RAM works with CL14, 3200 2T. However on SR4/TR4  I am unable to reach past stable 2933 (and a very wonky & unstable 3066 (sometimes posts, sometimes not).  Tried all the tricks I know from AM4 (pre-AGESA 1.0.06) -- raising SOC a lil, raising RAM V a little, geardown, command rate, ProcODT.. Basically all the tricks described by Robert Hallock himself here: https://community.amd.com/community/gaming ------------ I know these tricks/settings can be a little bit off for Threadripper so I post this question here: does someone have a recommendation/idea what to tweak to reach the same level as on the x370/AM4 platform? P.S. I followed the manual and populated banks D2, C2, A2 and B2. P.S.2 I also swapped the modules between the platforms. P.S.3. No change after upgrading to 1.50 Bios (with clear CMOS). Thanks for all the valid input on this topic!

Sorry no help here, I am just... stunned, shocked, and baffled that you can use 64GB of Ripjaws V in an AM4 board at 3200!

Nothing but Intel in the G.SKILL QVL:

Plus, are you using two 32GB kits of this memory, for the 64GB total?
