Someone found a way to upgrade bios 2.1 on h11dsi with ZS based cpu ?

Someone found a way to boot ES cpu on latest bios for the h11dsi ? I know that it's possible to boot on latest bios version on other sm board by downgrading agesa ,I've tried here dowgrading agesa and NBIO pei related driver but without success... Also is it possible to lower P1_SOCRUN ? Mine...

I'm using some cheap 2133mhz dimm that can be easily overclocked to 2666mhz , however as soon as I enable the overclocking mode the IF automaticaly runs at 1:2 ratio, if I force 1:1 at 2666mhz it doesn't post. System hardly post and not stable at 2400mhz oced with 1:1.

All values are displayed in hexadecimal you have to convert HEX to decimal in order to set the requested timing values. Also disable "gear down mode" so the board should stop automaticaly adjusting the timing to a "safer" value

According to @ExecutableFix Pbo doesn't seem to do anything. [EDIT] Fixed cosmetic issues present on previous XFR unlocked bios. H11DSi 2.0 XFR Fixed

I unlocked some settings in AMD CBS concerning Infinity Fabric , changing one of these settings make my H11dsi post stuck at 94 or D2 which seems to be related to Pcie Enumeration. Here's my custom bios H11DSi 2.0 XFR H11DSi 2.0 XFR Fixed -The board automaticaly boot on a offboard gpu, IOMMU...

Here's my result on a h11dsi rev 1.01 with High multi core preset (Unstable for me) High multi core preset with max frequency of 3450 mhz seems to be more stable

Check in your network if there's something new

Try to get into the IPMI and check the POST code in "POST Snooping"

I didn't test it yet so I can't give you any feedback sorry... (I'm kinda busy these days)

"Can't be oced" go check the thread title genius The purpose of this block is mostly to cool the VRM

Finally got the WB

It's untested, we don't know if Rome custom pstates or custom cpb settings works, and about zenstates, it still hasn't be updated for Rome if I'm right

I didn't received yet and I plan to mount it in january

Memory overclocking work like a charm I went from 2133mhz 16-15-15-36 up to 2666mhz 18-15-15-32 Memory encryption and ECC bit still enabled Epyc Memory OC Details for Result ID AMD F17 (Ryzen/ThreadRipper) Host Bridge (8x NUMA); 16x 8Go SanMax M393A2G40DB0-CPB ECC Registrée DDR4 (1.25GHz...

I edited my previous post so you should be able to check the picture in full res Yes you should at least run 4 dimm per socket Here is some bench with mixed workload on a 16 core epyc ,on a 32 one it will be even worst...

That what i get with 2 7551 ES clocked at 3.4ghz and 1 dimm per ccx I was running 1 dimm per die before and the score almost the same for this workload. You should really consider running 1 dimm per die (at least 4 dimm per socket) [EDIT] I was running 14dimm out of 16

Well it seems that you're already running with the latest bios... did you set the VGA priority option to "Offboard" in the pcie submenu ?

Try to at least run with 1 dimm per die and for your gpu you need to update the Bios, unfortunately the latest bios aren't stable for what I experienced. If you disable cpu core boost performance with the latest bios you won't be able to post.
