Edit updated links to 2701
bios 2701, names in links
fixes some bugs and raises settable fmax offset.
this is still based on the same AGESA version as 250x so dont expect any difference in Fclockiness against that version.

With new 2701 still random freezes with restarts. Back to working 2402.......

Tonight 12+ hours of RAM testing with 2701, everything is fine... but I'm nolonger on 4x8Gb.

My system was absolutely fine till I went to 4 x 8gb. I get shut downs without any error as if the system suddenly loses power and restarts

[Riplex]

With 2402 i get also restarts with default settings. ^^

Going back to Agesa Patch B with 2311..... Hope that works......

Uefi 2701 still does not resolve the issues with 4 dual rank dimms.
Somehow, 3000mhz is the maximum speed I can get out of 3200C16 ram.
It's like hitting a wall, anything above that doesn't post at all, regardless of voltages or timings.
The board displays F9 as post code, pointing to unstable ram.

Cheers.

2701, running D.O.C.P. 4x RAM sticks [not 2x like b4] and working D.O.C.P. timings with 3200 MHz [eventhough RAM is 3800 MHz].

So, what was the key?

Left everything on auto/default regarding Extreme Tweaker, besides values mentioned later in this reply. Am running two F4-3800C14D-16GTZN 2 x 8GB [16GB] Kits from G.Skill, although, as I'm lookin' now I made a mistake. There's perfectly good set of 32GB [4 x 8 GB] 3200 MHz Ryzen Neo memory running at 3200 MHz natively, sigh.

So I'm running it at default D.O.C.P., changed the speed from 3800 MHz to 3200 MHz, changed FCLK to 1600 MHz and only tRC is off charts in auto, I'll changed that too and will benchmark the memory, and MemTest it.


there, I fixed the timing 🙂 manually:

[Dawidowski]

So basically my 3900x cant run Fmax PBO with scalar 10x and 125hz.

Without there is no issues.
Cant do any changes to ram either cause I get random bluescreens.

Also for some reason D.O.C.O lands on 3597 mhz instead of full 3600.
Any ideas? And yeah my sample is a joke... so waiting for a 5900x

Seems I cant run Fmax Pbo without LLC3.. if I go below I Bsod

[Jamesisonfire]

Tried all of the BIOS' and the only way I seem to have got my 5900x stable with my DOCP profile (GSkill Neo Cas16 3,600Mhz) is to just use PBO. If I try and get AutoOC on it just has random restarts and crashes on Cinebench R23 randomly. 2701 gave me also random restarts without AutoOC and just PBO.
