Don't think that includes SODIMM modules, since I can't see my 4000Mhz b-die kit on there. Single ranked modules are 8gb, dual ranked are 16gb.
Single ranked modules, from my experience, tend to be easier for IMC to push.

 

Single rank certainly is easier for the IMC to handle. Double ranking is a bit like dual Simms per channel in the extra noise and load.

 

I recall BuildZoid talking about memory ranks and topologies, where dual rank would always lag around 200Mhz behind it's single rank cousin.

 

Another split trace with more ringback and a higher load will do that.

 

I use 3000 MHz Corsair RAM, which was working in my old P775 and the P870TM-R out of the box smoothly. When ordering new modules, I'd go for 3200 CL16/18 as well.

The SSDs in the model sit below the keyboard. There is no ample space, and actually I have been using mine without an additional cooler so far, and didn't have issues.

The Obsidian control is a must with the P775 on Windows IMHO, for Linux there are several open source tools that do the same.
My P870TM-R performs much better in this respect, actually the stock fan settings already ran pretty quiet on Windows, and with the clevo control center, there is the possibility to control the fan curve to some extent.
Obsidian certainly has more options. You can also just try with the stock control and upgrade to Obsidian if needed.

 

3200 or 3000, depending on price and availability. Either works well.

 

A 3200Mhz CL16 is a nice kit. Especially, when it has that 3200Mhz XMP profile, for easy plug and play experience.

Contrary to the 4000Mhz kit that I have. It has only 1 XMP profile for 4000Mhz CL19. That is only certified for x99 boards. Meaning, I have to manually test and tune the primary, secondary and tertiary timings by hand. If I want to run anything close to decent timings instead of the JEDEC garbage at 2400 that it defaults to.

 

Only thing I wish I knew before was how to couple the paired sticks with the 4 dimms. Since they work in a funny way.

 

Nice it has that to at least boot I suppose

 

For x99 yes, I never had it boot with XMP on the p870. And I kinda have a feeling that it might also set the VCCSA/VCCIO to stupid high values with 4000mhz XMP.
