My friend's DDR5 A die OC result on Unify itx

• 7800 cl32 44 44 30 2t
• vdd 1.66 / vddq 1.61 / sa 1.1 / vpp 1.875

Spoiler: 7800 CL32

So far 6 people I know have played with 18 a-die DDR5 sticks on 7 different systems, and here are some findings.
○ All sticks can boot up to 8000 (4 Apex and 3 Unify itx), Kingpin is locked at 1.435v.
(so it seems like a-die doesn't require really good imc since most of these cpu's imc couldn't boot even at 7200 with m-die)
○ Many sticks (in both slots) are likely oc possible to stable 7800 CL32 at 1.6v~1.66v.
○ Stable 8000 CL32/34-48-48 with some loose sub timings looks possible, but no one has passed TM5 extreme 10 cycles.
(Actually, most people are focusing on 7800 CL32 now)
○ Tras can't be tightened like m-die 310~320. Most likely 460+
○ Trefi max value 262143 gives errors in long session of TM5 or HCI.
○ No one has tried 1T yet, so don't know about 1T oc of a-die.

Evga released 1.15 earlier today says: “Adds support for DDR5 Renesas PMIC over 1.435V” but there’s a problem with the download file.

My daily gaming profile 8000 34-45-45-32 (46ns) with z690 Tachyon 13700K Gskills 6400z5 Adie air cooled

How safe is it to be running RAM at that voltage?

I have seen higher voltages for daily, I think you're good as long as you can cool them, the higher I have seen them is 47-49 Celsius, but I'm not an expert, its up to you to take the risk. I also have a safer profile 8000 36-46-46-52 , at a much lower voltage 1.46v / 1.45v vs 1.57v / 1.56v and I just lose about 1ns so around 47-48ns, this one the higher I have seen them is 41-43 Celsius.
