Crosshair VIII 2501's for testing

[uplink]

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:

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

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.

My 2 cents...
This BETA BIOS gives me the same exact problems as the previous BETA 2402 and the 'official' 2311.
The last version that worked good for me is 2206.
My rig is 3700X - CrossHair VIII Formula - 2x8Gb G.Skill F4-4000C17-8GTZR and 2x8Gb G.Skill F4-4133C19-8GTZR.
CPU is @stock, my struggle is to set the RAM to 3600 CAS14 (as they worked with BIOS 2206).
The system is rock solid both under Windows (Kharu) and under DOS (PassMark MemTest), can pass a +12h of stress test, but as soon as I reboot, it hangs on a variety of errors like "TEST CMOS", "CHECK CPU" or "LOAD VGA BIOS". Have to press the case reset button to make it boot again.
Sometimes I have BSOD loading Windows.

Here are my settings:





Nothing else set in BIOS, just DRAM voltage to 1.37v instead of 1.36v and disabled SATA (I have only NvME drives), WiFi and Bluetooth.
In the Power Supply Section, where there are 2 values suggested, I always set the highest one (140% instead of 130% and so on).

Any suggestion before reverting to BIOS 2206 is very much appreciated, thanks.

EDIT:
Testing under Windows with 1.075v VSOC instead of 1.1v, seems stable:

Hi, i'm new here.
Becouse of system instability since i updated to bios 2311, i 'm searching for a solution to make my system stable with new bioses.
I got a Ryzen 3900X coupled with a VENGEANCE RGB PRO 32GB (2 x 16GB) DDR4 DRAM 3466MHz C16 Memory Kit.
My system was "rock solid" with all bioses. The last bios i used was 2206 and i got full stability with memory main timings set to 15-16-16-16-51 @ 3800Mhz / 1800Mhz and 1.35V Vram.
All other settings was at default.
Now, with all new bios versions (even with the latest 2701 beta, thanks to Shamino), my sistem is unable to mantain stability at all, with random resets using my pc.

Please have you some advices?

Thankyou very much.

The new bios's that are being released aren't being tuned for Zen2/3000 CPU's, The platform has now being optimized for Zen3/5000 series chips. You may consider flashback to an earlier version more optimized for your CPU.

I'm using a ryzen 5900x and even with the new bios on my xrosshait viii hero I'm getting random restart with 0d error code on post

Hi, Spook161 thankyou for your contribution.
I agree with you. My system problems started with new firmware that are suited to new Ryzen 5000 series.

Actually i reverted to 2206 firmware to gain system stability, but here you are what kind of performance my system could gain with new firmware:

This is a bench with 2206 firmware:

So you will understand that it would be desiderable to update to the latest firmware.

I had to lower my infinity fabric freqency to stabilize my system. I'm 2 days now without a random reboot. Was using 3800/1900, and took it down to 3600/1800 to stabilize the system. I've seen some are reporting that they have to take it down to 3200/1600. Just take it down and stabilize your system for now, and hope they get a newer bios out that we can get our IF Clocks higher again. At least that is my approach.

A little confuse, because you said the same bios twice... BUT I can assume you used two different BIOS versions there.

So, I have a 3900x as well, and I tinkered with the clocks as well, but the 1usmus ryzen tuner helped me get my clocks up to 4.3/4.2 Ghz... its worth a look.

Hi bud,
Have you tried using DRAM Calculator? I mean also setting the PSU Section values.
