Today I tested with lower room ambient. The PBO+200MHz result I showed was thermally limited. So are most of my PBO+150MHz, as here is 1676 in CB R15

what was your ram voltage for 3733?
Not really tried 3733MHz much TBH. I fought a few days with gaining 3666MHz using The Stilt 3466MHz timings (1T GDMD), always just before ~3000% or after I'd get an issue. I tried lots of things. Then I spent nearly I day testing 3600MHz with higher % pass in tests. Then I tried say all [Auto] timings just to validate could I get 3800MHz. From there on profile fell in to place as I stopped targeting SCL 2. I believe I maybe able to go back to 1T GDMD on 3800MHz, even if I can't seems from benches I did tonight I'm not losing anything, but gaining stability.
TBH even the SOC/VDDG/VDIMM I use currently are some ball park figures which I felt would work from all the meddling I have done with this R5 3600 since 9th July.
I too like Nighthog had seen on certain targeted setting using too much voltage (may that be SOC/VDDG/VDIMM or all) made a profile fail then using more conservative approach.
For example VDDG: ~1.005V had worked well for 3666MHz any more used kill the profile quicker, dunno why. Now 3800MHz is ~1.012V, which is nuts when I look at it. Now from how I can use SOC: 1.031 VDDG: 0.956V for 3600MHz with SCL2, etc, perhaps I can tweak down them for 3800MHz.
Time will tell
Shocking how just ~2C lower room ambient got be nice scaling in CB R15 at same PBO+150MHz, also look at this WMV of RAM test
. Last 6 screenies of this album
are PBO+150MHz, 3800MHz v4.2, 1:1:1.
After so much time spent on this chip it still has had some more surprises

Im pretty done with 3800 profile. Tighten the timings down. Cant see major improvements vs only base timings + TRFC! Just slightly better.
Below screenshot while running. That particular run passed 8K before i stopped!
TRFC2 and TRFC4 are looking high. Is there any improvement if we "can" get them lower?
You also had good results
C14 too much voltage spend for little gain IMO.
TRFC2/4 not used as before.
