is there any list of 100% compatible waterblocks for this board?
I found some cheap models: 
Barrow SKYLAKE-E-LGA3647 Server Block- Acrylic Barrow SKU LTYK-LGA3647-AC - $59.99
BYKSKI CPU-SKYLAKE-E-V3 - $44
BYKSKI CPU-SKYLAKE-E-V3 silver - $62
Has anyone used them?

The Phanteks and Bitspower ones both work fine, I don't think I've tried my watercool one on it though so can't say for certain.

Has anyone managed to install WinXP on the SR-3?

Did not find BCLK change options in BIOS? ASUS and Gigabyte has such feature, what about EVGA?

That look like a beast I am sure who ever buys it is going have fun building a system.

Сan someone tell me if this motherboard supports intel optane persistent memory? I see that it has only 6 slots, I have two 256gb optane modules, if I install them, I still have 4 slots for RAM left. Thanks!!!

Hello I’m hoping someone can help me.
I’ve been tinkering with this SR3 Dark and 3175X Combo now for a couple weeks and the onboard nvme drives are working flawlessly. I got myself an early Christmas present with the ASUS Hyper M.2 X16 Gen 4 Card and four Solidigm 2TB P44 Pro drives to go with it.
If I enable PCIE Card(Non-VROC) I can get two of the four drives to show up in bios(all four are showing as being present with the onboard LEDs of the Hyper card).
If I don’t enable the PCIE card selection in BIOS, it never shows up more than one nvme drive.
I don’t currently have a VROC key as I was hoping to avoid using one, but if that is what it’ll take for me to have all four drives enabled, then I’ll purchase one promptly.
I have tried the card in slots 3/4/5/6 and all show the same story. PCIE also never shows above x4 wherever the card is installed.
Thank you for any insight into this, sorry for the noobish questions, this is just my first foray into nvme raid.
