Sorry for replying this late

Well i just installed zenstates and ran
Code:
python zenstates.py -p0 -f  20 -d 2  -v 3A --c6-disable
Code:
usage: zenstates.py [-h] [-l] [-p {0,1,2,3,4,5,6,7}] [--enable] [--disable] [-f FID] [-d DID] [-v VID]

Sets P-States for Ryzen processors

optional arguments:
  -h, --help            show this help message and exit
  -l, --list            List all P-States
  -p {0,1,2,3,4,5,6,7}, --pstate {0,1,2,3,4,5,6,7}
                       P-State to set
  --enable              Enable P-State
  --disable             Disable P-State
  -f FID, --fid FID     FID to set (in hex)
  -d DID, --did DID     DID to set (in hex)
  -v VID, --vid VID     VID to set (in hex)
  --c6-enable           Enable C-State C6
  --c6-disable          Disable C-State C6
In order to get 3.4Ghz@1.187V on P-sates 0 on both CPUs

Hi everybody.
Help me find the bios for h11dsi rev2 for 7b12 processors, it does not start with a turbo boost.
The links in the topic are dead.
Thank you very much!

Sorry for waking up any undead... but..
working towards getting this 16 core @4Ghz stable. im @ 3.95 stable for now. trick is less voltage, not more.. (maybe depends on motherboard, im using EPYCD8-2T)

testing on cp2077 and space marines two.. ill try cinabench at some point. and its not a golden chip. i have a batch of these from HPDL325 G10 and all get same clocks.. as i get high stable clocks i apply settings to other workstations with same chips.

Ok. Something quite odd is going on. I dont know if maybe someone can help me get in touch with Zen states dev or something.

I have stable 3.95Ghz on the 7351P on Asrock EPYCD8-2T as well as on HPe DL325 G10.

I use 1.356v for 3.95GHz and TDP goes anywhere between 215w o 250w depending on bench. Stable. I use CB, CPUz and some games to bench (GoW ragnarock, CP2077, Space Marines 2, Forza Horizon 5)

When I set it to 4Ghz. Normal tasks are fine but as soon as I try anything heavy, PC reboots. It just shoots up TDP to 300w+ even though its only a .05 increase in clock speed. Lowering or rasing voltages will give exact same result.

I set cTPD in bios at 285w and same thing happens. This is from a Stable 3.95Ghz. I'm so lost as to why TDP would shoot so high.

Anyone have an idea? My cooling is overkill. @3.95ghz my temps are 73c max (was lower days ago but I did a CPU swap and was too lazy to re apply fresh paste - I sometimes swap to a 64 core for work).

If we get across this, the 7351 could be a great 16 core performer at its dirt cheap price with simple OC
