And Tdie is just Tctl - 20 in HWinfo, has nothing to do with Sense Skew and is *not* a sensor.

It's a very easy to use editor. You can create your own XMP profiles or tune them for your Ryzen system.

Oh I understood that I needed the professional version to write to an SPD, my question was more a general one of why it might be an advantageous or desirable thing to do beyond fixing a corrupted SPD. I think dorbot gave a good answer to this;

I had a quick look about what he was on about but there were too many numbers and options I know nothing about. I'm sure its easy if you read up a bit on how it all works and what data you actually need to enter, how to enter it. I think you can take your 3200MHZ ram and stick a profile that works at 3600MHZ with 1.39v or whatever for your system for example.. That overclock might be optimistic but just an example.

So after the May update I may have my 3600Mhz RAM running natively on strap (ever hopeful!) but if I can run them at 3800 or 4000 with manual timings and voltage etc I could then save those directly to the spare (extreme) XMP profile on the DRAM module. This tweaked for your build set of timings would then be selectable in bios so you dont have to re-enter manually. I could do it now for 1.35v  14,14,14,14,34 @3200 but there, are like I say, many other timing data I know nothing about.

Thanks for the info, it is sort of what I assumed, but was not sure, the business of writing to an SPD is a new topic for me.

I just had a failed reboot again, after several successful ones (including cold boot). What was different? This time I rebooted right after stopping a IBT AVX run, which means that temps were still higher than normal.

It's possible that higher RAM temps combined with lower DRAM voltage are the source of the reboot training failures. It should be possible to reproduce this.

Currently I am testing BLCK higher than 103.2 using higher DRAM temp, though. So this will have to wait until later.

Oh i know that, i have that deleted i dont pay attention to it. I even use tctl in RTSS when in games so tdie for me is useless anyways. Tctl has always worked right for me with 902/1002 so hoping the next official BIOS it works the same.

Darn, had my fingers crossed that 0083 would stop my motherboard connected fans from fluctuating in speed (The sound of it changing really grinds my gears)

Other than that no issues with 0083.

I'm going to try and increase my RAM Speeds. Got Corsair LPX's, so let's see how they go

Hey guys, haven't been able to keep updated with this thread for a few days. Will try to go through it later this week. Ideally you'll report verified issues using the form linked in OP. Anyhow, here's the latest beta BIOS 1106. It's similar to 0081 (AGESA 1004a) but adds a couple of bug fixes like CHAFan 3 not being adjustable.

edit: Sub-par BIOS removed.

So this doesn't do the Asus EC flash / 90MHz ref clock thing? PState 0 VID increase work?

Does it have the 003 90mhz bclk fix in it as well or thats still being tested? I'm still waiting for an official one so even small bugs are ironed out. I can boot at 3200mhz with a reset button hit then its fine until i cold boot again.

Hrm so is there still not a real way to adjust for the x series offset to tctl for both load and idle temps? Do we just have to wait until AMD caves and removes it in one of their AGESA updates?

Thats not the issue, it can be done on a BIOS level as well. As I've stated for me on BIOS 1002 my temps are correct under tctl, idles at 28°C reaches 50°C under realbench load with a water temp of 28°C, considering my gpu at 215w reaches 40°C and i have a restrictive gpu block my cpu should run hotter and does.
