x370 pro gaming memory issue

heres what im using
gskill f4-3200c15d-16gtz (its a 2 x 8gb kit = 16gb)
it is normal tridentz but heres the deal the c14 and c15 3200 kits are all samsung b die
NOT ALL THE C16 KITS ARE ! be warned .......
my actual installation is then as follows
two sticks of ram at 8gb each inserted into slot a2 and b2

now with version bios 2
i can either just click xmp and it loads them ok
or manually set them
either way
i show
15
15
15
35
but when the system boots it always loads 16/15/15/35 into windows (even still says 15/15/15/35 in bios)
no real problem i cant wait for later bios
the other settings i change are
SOC voltage to 1.00 volts and i set it fixed voltage and LLC level 2
vcore is set to fixed volts and llc level 2 also
but i use the p states to tune the cpu and the settings for that are
9c which equals 3900mhz
8
27 which equals 1.306 volts vcore

bryan at tech city (search tech city on you tube) has a very nice simple and easy to understand overclocking guide for the p states cpu on his you tube channel its well worth a watch (is based on taichi bios but should be similar to yours)

i think the main problem at the moment is the amd agesa code not really liking 4 sticks of ram or double sided ram both these together are forcing slower speeds
combined must be even harder

we can only guess or assume as to how good the difference will be with the may 1005 agesa

i think/hope it might be reasonable to hope for max 3600 on single sided pair of sticks eg 16gb max
it would be nice to assume/hope for 3000 on 4 sticks or double sided eg 16gbx2 or 8gbx4 sticks 32bg max

it should be (less strain on the cpu mem controller) but

it still is dealing with dual sided sticks in the above 16gb x 2 kit
at the moment the
proverbial 'rule of thumb' is
for best chance of 3200 speed
use single sided ram sticks (these can only be upto 8gb each)
with samsung b dies (once again these seem only to be 8gb sticks))
and only use two slots (a2 b2)

i think theres 32gb systems around for sure maybe 2666 and 2993 speeds but the timings seem to be high and the success low

were talking some 16gb x2 kits not even booting

i feel your asking for someone to come up with a magical suggestion for ram 32gb kit that just dosnt exist at the moment
its just early days for the brand new am4/ryzen platform very much like the early x99 intel systems with the same sort of ram choice/memory speed issues

to sum up
you can have hopefully have a good chance to get 3200 and some cl14 or cl15 timings but only on 16gb max ram

if you must use 32 gb then you will have to expect slower speeds and maybe higher latency

now on the upside its reasonable to expect a new agesa code bios to be around in two weeks maybe it will be a very good improvement
