red5 That's the "EK-FC Radeon Vega - Acetal+Nickel" going on my Sapphire Radeon RX 64 (reference) card. The only other difference with the other current EK listings is the look. One is clear + nickel, clear + copper, and all black. Dimensions are all the same and should work on all current RX Vega 64 reference cards. As for the different chip arrangements (as reported by Tom's Hardware), those were engineering samples as far as I know. This weekend I'll work on a conversion video (going from stock cooler to EK water block).
Ok, now to just find one in stock. I still have a bunch of prep work to do on my case, so not a huge hurry. Was hoping to have it done by my LAN party in late October
Disregard ALL of my clock figures. The new version of the drivers have my clocks jumping all over the place and peaking at 1700 max but averaging around 1690, so I have no clue what it is actually doing.
It seems like the new drivers are maintaining some form of the chill function even when chill is disabled. It will no longer hold a set number as the clock.
I've only jumped into Global Wattman settings and changed my setting to "Turbo" (from balanced) which actually resulted in a lower Passmark score for my graphics. I guess I'll worry about it more once I watercool it when the NEOChanger arrives.
