CPU TEMPS

So I just finished my Threadripper build and it idles at 44-50. I see people saying to minus 20 or 27 from that to get the actual temperatures. Is this correct? I know the tDie thing was -20 for my Ryzen 1800x build. Threadripper i'm getting mixed answers through searches

CPU SPEED

Core temp reads out 3697.79mhz on all cores. I didn't OC anything in bios. Any reasoning to this? I'm totally fine with it but not sure what's causing this or if its possibly a false reading.

RAM SPEEDS - Using Corsair Vengeance 32gb 3400mhz

I just wanted a fresh clean install of Windows 10 and so I used the default 2133 speed for my ram. After the install I tried the XMP Profile (3200mhz) and failed. Didn't bother with Profile 2 as it was 3400. So I then bumped 1by1 tried 2400 and then up until 2933 is where I maxed out. Using the MSI Pro Carbon X399 mobo. Has anyone been able to reach higher?

The temp offset thing has largely been changed, but it depends on what you're reading temps with. +27 was the correct offset for threadripper previously. Whatever you're using to read 44-50(ryzen master perhaps?) then that's likely accurate.

3700Mhz is max all core boost on a 1950x, mine does precisely the same at stock settings.

I too chose Corsair Vengeance ram, mine is 3200Mhz LED model number CMU64GX4M4C3200C16R which is a 4x16(64GB kit) and also, like you, I'm stuck at 2933Mhz. This is what we're at with SK Hynix chips, which mine are and yours likely are. That said the bandwidth is jaw dropping even at this speed. I tightened timings to 14-14-14-14-34-1T @ 2933Mhz and 1.36v and bandwidth pushes close to 88k MB/s read/write/copy...

We'll just have to wait for moar AGESA updates to be implemented by the board makers to get higher speeds.
